Injection mold design structure

1, mold temperature control system 

Injection molding process in order to meet the requirements of the mold temperature, mold temperature control system needed (such as: cooling water, hot water, MASTER mould maker‍ oil and electric heating systems, etc.) on the mold temperature regulating devices. 

2, the exhaust system 

In order to successfully discharge cavity gas exhaust ducts often open in the mold parting surface, putting a lot of mold or other moving parts: the MASTER book mould‍ (eg sliders) between the exhaust may also play a role. 

3, the other structural parts 

Means to meet the requirements of the mold structure and set up on parts (such as: fixed plate, moving / fixed template, supporting the head, bearing plates and connecting screws, etc.).

Composition injection mold design

1, molded parts

Given the shape of the molding material, the structure, the size of the parts, usually consists of core (punch), concave cavity and threaded core, inserts and other accessories.

2, gating system

It is the molten plastic injection MASTER injection mold maker‍ nozzle toward passage by the closed mold cavity, usually by the sprue, runner, gate and cold slug well composed.

3, the guide member

In order to ensure the guide member when the movable mold and the mold is closed can be accurately aligned and set, from the positioning guide action by the guide column and which is composed of the guide sleeve, the top of the panel there is also provided a mold of the guide member, to ensure ejection mechanism is smooth and reliable movement.

4, stripping mechanism

Realization of plastic MASTER plastic drawer mold‍ and mold gating system device, a lot of its structure, the most commonly used plunger, pipe jacking, such as the top of the roof and pneumatic ejection mechanism, generally by the mandrel, reset lever, slingshots, ejector fixing plate roof (top ring) and roof pillar / bushings and other components.

5, core-pulling mechanism

For concave side holes or side plastic parts, was the top before stripping must be separated laterally Pulling or slider (lateral type) in order to successfully mold.

injection mould design of the thermostat system

In order to meet the mold injection process MASTER flower pot mold requirements, the need for temperature control system for injection mould design temperature can be adjusted. For thermoplastics injection mold, the cooling system is primarily designed to cool the mold. The common MASTER injection moulder is to create a cooling mold cooling water passage in the mold, the use of circulating the cooling water heat of the mold; heating a mold in addition to the cooling water passage of hot water or steam, but can also be installed in and around the mold power heating element.

injection mould design of molded parts

injection mould design of the molded part from the core and die components. The core is formed in the surface of the article, to form the outer surface of the MASTER plastic drawer mold shape of the article. After the mold core and cavity will form the mold cavity. According to MASTER milk crate mold and manufacturing requirements, core and sometimes die by the combination of several pieces, sometimes made ​​whole, only fragile, difficult to machine parts using inserts.
