What is the automotive plastic mold

There are many ways to classify automotive plastic molds, according to the different methods of plastic parts molding and processing can be divided into the following specific categories. There are injection molds, compression molds, transfer molds, and extrusion molds, in addition to these, there are vacuum molding molds, compressed air molds, etc. Today I will take you to understand the automotive plastic mold in the two classifications:

1、Injection mold

Injection mold is also called injection mold, its molding process is characterized by the plastic raw material is added to the injection molding machine heated barrel after high-temperature hot melt, after the screw or plug is pushed, through the nozzle and mold pouring system into the mold cavity, plastic raw materials in the cavity pressure, cooling and finally curing molding process.

2. Compression mold

The compression molding process is characterized by the direct addition of plastic raw materials in the open mold cavity, and then the closing step, the plastic material in the dual role of heating and pressure melt, and then the injection molding machine to a certain pressure, through the pressure of the hot molten plastic raw materials will be filled to the cavity. At this time, the molecular structure of the plastic material will produce a chemical cross-linking reaction, slowly hardening and shaping.

The difference between diagonal top and flight position in automotive molds

The slant top is one of the components of our auto mold design, before the design of the auto mold, the design will take a series of structural analyses of the product structure to the 3D drawing provided by the customer, then, according to the demand of the product structure, a mechanism will be designed to deal with some barbs.

Also, deal with the inverted hook of the mechanism and the navigation position, so what is the difference between the slant top and the line position in the automotive mold? Today I will take you to understand one or two.

The condition of the existence of the line and the inclined top in the automobile mold is to change the direction of movement from vertical to horizontal when the mold is opened. But the biggest difference between the two is that they are different in the object of the driving force of the movement: the movement of the line position is by the movement of the front and rear mold opening and closing, and the slanting top is dependent on the movement of the ejector plate and movement, thus, it can be seen that the design of the slanting top is associated with the stroke of the ejector plate.

The above is the biggest difference between the design of the slant top and the design of the line position in the automotive mold.

How to maintain the automotive plastic mold

 Any item needs to be maintained to prolong its service life, and the auto plastic mold is so expensive that it needs to be maintained.

A responsible mold manufacturer should first understand the basic situation of the auto plastic mold, and can first equip each set of the mold with a resume card, which should be recorded in detail, as well as statistics on its use and care (lubrication, cleaning, rust prevention) and damage. In this way, it will be possible to find out which parts and components of the automotive plastic mold are damaged and to what extent, and to find solutions based on this information. It should also be necessary to have information about the parameters of the molding process and the materials used for the product, which can shorten the mold trial time as well as improve production efficiency.

At the same time, our manufacturers should test the performance of the automotive plastic mold under the normal operation of the injection molding machine and mold, and measure the size of the injection molded parts with professional machines, which can help to determine the existing state of the automotive plastic mold and identify the damage of the cavity, core, cooling system, and parting surface. The information on the plastic parts can also help to determine the degree of damage to the automotive precision injection mold and find more suitable repair solutions.

This shows the importance of the maintenance of automotive plastic molds.
