The composition and function of injection mold

The injection mold consists of seven parts: molding parts, pouring system, guiding mechanism, ejecting device, lateral parting and core extraction mechanism, cooling and heating system and exhaust system, etc.

1. Injection mold molding parts

Injection mold molding parts are the parts that constitute the mold cavity, mainly including: convex mold, concave mold, core, molding rod, molding ring and insert and other parts.

2.Injection mold casting system

Injection mold pouring system is the plastic flow channel from the nozzle of injection molding machine to the cavity in the mold. The common pouring system is composed of main flow channel, diversion channel, gate, cold cavity, etc.

3. Injection mold guiding mechanism

The injection mold guiding mechanism mainly has the function of positioning, guiding and bearing certain lateral pressure to ensure the accurate closing of dynamic and fixed mold. Mold guiding mechanism consists of guide pillar, guide sleeve or guide hole (directly on the template), positioning cone, etc.

4. Injection mold ejector

The ejector device of injection mold mainly plays the role of ejecting the parts from the mold, which is composed of ejector rod or ejector tube or push plate, ejector plate, ejector fixing plate, reset rod and pulling rod, etc.

5. Injection mold lateral parting and core extraction mechanism

The role of lateral parting and core extraction mechanism is to release the lateral convex mold or extract the lateral core, usually including oblique guide pillar, bending pin, oblique guide groove, wedge tight block, oblique slider, oblique slot, gear rack and other parts.

6. Injection mold cooling and heating system

The role of injection mold cooling and heating system is to regulate the mold process temperature, composed of cooling system (cooling water hole, cooling water tank, copper pipe) or heating system.

7. Injection mold exhaust system

The role of the injection mold exhaust system is to remove the gas from the cavity, mainly composed of exhaust grooves, fit gaps and so on.

The injection mold consists of two parts: the moving mold and the fixed mold, the moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the mold is closed with the fixed mold to form the pouring system and cavity, and when the mold is opened, the mold is separated from the fixed mold to remove the plastic products. In order to reduce the heavy workload of mold design and manufacturing, most of the injection molds use standard mold frames.

To buy plastic molds, if you can choose a good injection molding supply company you can cut down a lot of shopping time, and the final product you choose will be very good. There are many companies in the market that you can choose from, but many customers directly choose Keyplast. A very good China plastic injection supplier, from the beginning of the planning to the final product, can end a one-stop service, can bring customers very much convenience.
