Take you to understand the structure and composition of the injection mold in one minute

Injection mold is a tool for the production of plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. At the same time, injection molds are the main equipment for injection molding production. In the entire injection molding production process, its quality is directly related to the quality of the product. inferior. Moreover, since the mold occupies a large proportion of the production cost of injection molding processing enterprises, its service life directly affects the cost of injection molded products. Therefore, improving the quality of injection molds, maintaining and maintaining them well, and extending their service life are the top priorities for cost reduction and efficiency enhancement in injection molding production. Today, the editor will take you to understand the structure and composition of the injection mold. If you are interested, come and take a look!

The injection mold is mainly composed of the following structures:

1. Molded parts The parts given the shape, structure and size of the molding material are usually composed of cores (punch molds), concave mold cavities, threaded cores, inserts, etc.

2. Pouring system It is a channel that leads the molten plastic from the nozzle of the injection machine to the closed cavity, usually composed of a main flow channel, a runner, a gate and a cold material well.

3. Guiding part The guiding part is set to ensure the precise alignment of the movable mold and the fixed mold when they are closed. It plays a role of guiding and positioning. It is composed of a guide post and a guide sleeve. Some molds are also set on the ejector plate. The guide parts ensure the smooth and reliable movement of the demoulding mechanism.

The inside is composed of a demolding mechanism, a core pulling mechanism, a mold adjustment system, and an exhaust system.

4. The demoulding mechanism is a device that realizes the demolding of plastic parts and the pouring system. There are many structural forms. Commonly used are ejector, pipe, top plate and pneumatic ejector. Generally, it consists of ejector, reset rod, slingshot, Mandrel fixing plate, top plate (top ring) and top

Combination of plate guide post/guide sleeve.
