The correct maintenance of the Crate Mould(FURNITUREMOULD) definitely involves a much more versatile approach to the tool's removal from the production stage, with almost no organized crate mould. Regularly inspect, test and correct the method of crates. Typically, such inspections provided by crate mould are performed by unskilled persons. These people are not fully familiar with the principles and practices of the manufacture and manufacture of crates. If the crate mould appears to be in a reasonable state and does not give any serious trouble during the operation. Just rush to clean up, then set aside, instead of always in the appropriate place to store, waiting for the next production order.

As already explained, it is generally not necessary to provide a suitable storage location or equipment, which makes it more difficult for the maintenance engineer to effectively check the condition of the crate mould when not in actual use. It should be remembered that these features can be severely degraded unless careful when storing the mould. These features include:

Wet atmospheric conditions,

Failure to eliminate all moisture from the crates during production stoppage

Indiscriminate contact with the moulding workshop, or the box, other metal objects on the shelves, careless handling, etc.

Crate Mould(FURNITUREMOULD) tool ejection systems vary greatly in complexity and design. The primary function of any injector system must be to remove the molded part from the mold when opened, thereby allowing the press to be recirculated. Once exiting the crate mould, the assembly is free to fall into the molding area under gravity or otherwise removed, for example. Through the robot. Typically located in the core portion of the mold, the ejection system can be actuated by the opening act of the molding machine or mold.

Some of the most commonly encountered spray components are listed and described below.

(a) Ejector Prohibition: The spray bar mechanically connects the mold injection system to the mechanical interface of the molding machine. The rod can be attached to the mold (for example by means of a thread) or used as a door knocker without any mechanical connection between the mould or machine.

(b) Ejection plate: The ejection lever transmits the ejection force as a single point load to the center of the ejection plate. The applied load is distributed to various components that are attached or contained within the panel assembly. The spray plates must be rigid structures to withstand the relatively high cyclic loads imposed on them during use. If the plate is bent or bent under load, tool wear may occur, which may significantly shorten the life of the mold.

(c) Support column and parallel block: These components pass the clamping force through the die back plate and directly to the core plate around the ejector plate groove. The struts are also used as guides for positioning the ejector plate assembly. The amount of jet stroke available is primarily determined by the total height of the two components.

Thimble and blade: These head components are trapped between the ejector plates. The thimble and the blade are typically located within the core assembly, are located in the reaming hole and are grounded flush with the top plate, and the top plate is fully retracted. Due to the continuous friction within the core, components such as these are prone to wear during use. Most pins and blades mounted on modern molds are standard components, usually produced in large quantities, and catalogs are also ordered. Thimbles and inserts are good examples of standardized applications that reduce tool maintenance and construction costs.

Peeling plate: The use of the peeling plate enables the applied ejection force to be transmitted to the periphery of the molded part, thereby producing a more advantageous spraying method than the pin or the blade. They are often used in thin-walled molded parts to avoid damage. The release panel is located in front of the core panel, above the extended core, which is also used to position the panel, typically a tapered fit. The peeling plate is guided over the main position of the mold. The pop-up force can be applied to the board in a variety of ways, for example, (i) by the opening act of the press; (ii) directly by the jack; (iii) the top board is indirectly pushed through the putter.

It is sometimes found that the walls of the Daily Necessities Mould(FURNITUREMOULD) tend to bend inward and this effect can be mitigated by keeping the core cooler than the mold cavity.

This seems to contradict what has already been said, because bending always occurs where there is a thicker or hotter material. If you consider how the daily necessities mould is filled from the center gate of the base, you will find that the flow of material is radial at the bottom of the box and is almost straight on the wall, creating a large shear force.

Therefore, the main contraction will be in that direction, and the perimeter of the wall will eventually be larger than the size of the base. The binding effects of the base caused them to bend inward. If the core then cools more than the cavity, the material inside the wall will shrink less than the outer material, and the end result is that the wall straightens. If the core cools too much, the wall will bend outward.

Improper care is the main cause of damage to Crate Mould(FURNITUREMOULD). Using a metal screwdriver to remove the jammed parts can result in scratching the surface of the cavity. This scratching results in a cosmetic defect on the molded part, but may also affect a particular size and cause it to out of tolerance.

It may also act as an undercut and cause subsequent parts to hang without popping or at least breaking. Failure to lubricate moving parts (such as slides and cams or guide pin bushings) will cause the sliding parts to wear out, eventually causing the parts to get stuck.

Crate mould that use an improper rag to wipe the cavity surface can also cause minor, significant damage to highly polished surfaces. Improper processing can cause serious damage, such as when the technician uses too much injection pressure at the start-up and flashes the mold. The flash can be between the guide pin and the bushing, or between the pinholes of the ejector, or between vertical separations, and can force the side walls to move outward or around the sliding mechanism and cam. This locks the mold in place when trying to open it.

The so-called barrel temperature control refers to how the plastic in the barrel is uniformly heated from the raw material to the plastic viscous fluid, that is, how to configure the temperature of the barrel. The barrel temperature adjustment should ensure that the plastic is well plasticized and can be injected smoothly without causing decomposition. This requires that we do not consciously lower the plasticizing temperature because of the sensitivity of the plastic to temperature and forcibly filling the Crate Mould(FURNITUREMOULD) with injection pressure or injection speed. The melting temperature of plastics primarily affects processability, but also affects surface quality and color.

The control of the material temperature is related to the crate mould. The parts are large and simple, and the part weight and injection volume are close to each other, requiring higher baking temperatures, thin walls, complicated shapes, and high baking temperatures. For thick-walled parts, some of which require additional operations, such as mounting inserts, can be used to lower the temperature of the oven. To determine if the temperature of the plastic solution is appropriate, use a jog operation to observe the low pressure air and observe the appropriate temperature. The material should be sprayed vigorously, vigorously, without foam, without curling, and with continuous illumination.

The material temperature is generally configured in ascending order from the feed portion to the discharge portion, but the excessive exposure of the plastic to prevent decomposition and the change in the color of the part may also be slightly lower than the middle portion. The incorrectly configured material temperature may sometimes result in the card's screw. Fault, the screw will not rotate or idle. It is also possible that the injection pressure is too high or the screw check ring (meson) does not allow the thin molten material at the front of the cartridge to flow back into the feed zone.

1. The Daily Necessities Mould(FURNITUREMOULD) has large differences in the particle size of the raw materials, and it is difficult to uniformly plasticize and the gloss is poor. For this purpose, the raw materials should be sieved.

2. The recycled material or nozzle material in the raw material of the daily necessities mould is excessively added, which affects the uniform plasticization of the melt and has poor gloss. Therefore, the amount of recycled material or nozzle material added should be reduced.

3. When the temperature is adjusted, some of the raw materials will decompose and change color, resulting in poor gloss. For this purpose, raw materials with good temperature resistance should be used.

4. The content of moisture or volatile substances in the daily necessities mould raw materials is too high, volatilizes into a gas upon heating, and condenses in the cavity and the melt, resulting in poor gloss of the plastic parts. For this purpose, the raw materials should be dried beforehand.

5. The dispersibility of some additives is too poor, and the gloss of plastic parts is poor. For this purpose, additives with better fluidity should be used.

6. Raw materials are mixed with foreign materials, miscellaneous materials or incompatible materials. They do not mix uniformly with the raw materials, resulting in poor gloss. For this reason, these impurities should be strictly excluded in advance.

7. If the amount of the lubricant is too small, the fluidity of the melt is poor, and the surface of the plastic member is not dense, resulting in poor gloss. To this end, the amount of lubricant should be appropriately increased.
