Plastic mold processing is basically divided into static mold and movable mold. The one with sprue sleeve on the side of the injection head processed by the plastic injection mold is a static mold. The static mold generally consists of a sprue sleeve, a backing plate, and a template. A simple mold can also use a thicker template instead of a backing plate. Up. Plastic mold processing sprue sleeves are generally standard parts, and it is not recommended to cancel unless there are special reasons. The use of sprue sleeves for plastic mold processing is conducive to mold installation and easy replacement, without self-polishing. Plastic mold processing Some special mold sprue sleeves can be drilled out or cut by taper line cutting. When part of the mold must be demolded from the static mold, the static mold release mechanism must be added. The structure of the movable mold for plastic mold processing is generally a movable template, a movable mold backing plate, a demolding mechanism, and a mold foot and a fixed plate for the installation.
In addition to the stripping rod, there is also a return rod in the demolding mechanism. In the injection molding part of the plastic shell, a spring must be added to realize functions such as automatic demolding. The basic structure of the mold is also indispensable for plastic shell injection processing, as well as guide posts, cooling water holes, and runners. Of course, the inclined guide mold also has inclined guide boxes, inclined guide posts, etc. When designing a mold for a product, the plastic shell injection molding process must first set the basic structural dimensions of the mold to prepare materials to speed up the mold manufacturing. Plastic shell injection molding complex products should first draw the product picture, and then determine the size of the mold.
The gate is directly related to the beauty of the plastic part. If the gate design is not good, defects are likely to occur. It is easy to produce snake-like flow when the plastic shell is sprayed without any obstruction. Plastic shell spraying should also be designed for overflow and exhaust for products with high requirements. The ejector pin can be used at the overflow, and there should be no overflow flash on the template, so as not to affect the life of the mold. There are also more and more software for plastic shell spraying design molds, and most of them rarely use pencils to draw mold drawings.

Plastic injection molding is one of the most common methods for mass production of plastic products. Examples include chairs, disposable tableware, crates, toys, consumer electronics housings, Lego blocks, etc.
The injection molding machine consists of three main parts-injection unit, plastic injection mold and fixture. The barrel heats the plastic particles. These molten plastics will move forward in the barrel through the screw system. Once completely melted, it will be "injected" into the mold cavity and formed. It will cool and harden to form a plastic part.
Injection molding automates the mass production process. One injection may result in the production of many parts, depending on your mold design. There are many types of molds that can further increase the productivity of a single injection of molten plastic, such as laminated molds, tandem molds, and multiple cavitation molds.
When we choose mass production, we will definitely support predictability, efficiency and less troubleshooting. Plastic injection molding is undoubtedly an established manufacturing method. High-precision engineering plastic materials can be bought on the market to advanced injection molding machines to meet different manufacturing requirements.
Mass production using injection molds is very useful for achieving higher efficiency. Once the design is designed for a specific purpose according to the customer's choice, the molding process will not take long. This makes it more effective in mass production and also more effective in terms of yield.
It has enhanced strength.
It is very common to use additives such as glass fibers in plastic materials. These highly engineered composite plastic materials have the durability of their raw materials. And, there are thousands of different types of materials on the market to meet different needs.
Most importantly, the density of the plastic when it is just molded makes it stronger. There is a great need for durable parts in the market, and plastic injection molding provides you with a lot of flexibility that other molding processes cannot provide.

1. Cavity layout. Determine the number of cavities and their arrangement according to the geometric structure characteristics of the plastic parts, dimensional accuracy requirements, batch size, mold manufacturing difficulty, mold cost, etc.
2. Determine the parting surface. The position of the Plastic furniture mould parting surface should be conducive to mold processing, venting, demolding and molding operations, and the surface quality of plastic parts.
3. Determine the pouring system (the shape, location and size of the main runner, sub-runner and gate) and exhaust system (exhaust method, exhaust slot location, size).
4. Select the ejection method (ejector, pipe, push plate, combined ejector), determine the undercut treatment method and core pulling method.
5. Determine the cooling and heating method, the shape and location of the heating and cooling groove, and the installation location of the heating element.
6. According to mold material, strength calculation or empirical data, determine the thickness and dimensions of mold parts, shape structure and all connections, positioning, and guide positions.
7. Determine the structural form of the main forming parts and structural parts.
8. Consider the strength of each part of the mold and calculate the working size of the molded part.
If these problems are solved, the structure of the mold will naturally be solved. At this time, you should start to draw the mold structure sketch to prepare for the formal drawing.
Plastic trash can molds have very high requirements. Generally, environmental protection PP materials are mostly used, which can produce a bright surface and then do film printing and other treatments. It becomes a high-end trash can, but it is not necessary to make a good trash can. Easy. First of all, the quality of the mold must be controlled, including mold design, mold assembly, hot runner and cold runner selection, etc. As the saying goes, laymen watch the excitement, and experts watch the doorway. Annoy mold tells you how to better control plastic Problems in the mold processing process?
Mold asseFactory Custom newly design Plastic Injection dustbin Mould (JTP-A0119)mbly is just like assembling a machine. Every component and every screw cannot be wrong, otherwise the consequences will be very serious, from the slightest to the product defect, affecting the production, and the other to completely damaging the mold and causing scrap. Therefore, the assembly work must be very meticulous. During the assembly process, pay attention to the cleaning of the mold, especially the waterway and screw holes. The iron filings must be blown out, otherwise the customer will be very angry and the consequences will be very serious.
