Introduction and Composition of Injection Mold

Because plastic products are usually mass-produced or mass-produced, the use of molds requires high efficiency, high quality, and minimal or no processing after forming. These must be considered comprehensively when processing injection molds.

1. Determine the parting surface and gate position of the injection mold based on the usability and molding performance of the molded product.

2. Considering the craftsmanship of the mold manufacturing process, the design plan is determined based on the equipment condition and technical strength to ensure that the mold is easy to process from the whole to the parts and to ensure dimensional accuracy.

3. Consider the productivity of injection mold processing, increase the number of injections per unit time, and shorten the molding cycle.

4. Show dimensions and structures such as holes, columns, protrusions, and recesses that require precision on the mold. That is to say, do not process or process the formed product after forming.

5. The mold structure aims for simple applications, is stable and reliable, has a short cycle and low cost, and is easy to assemble, repair, and replace vulnerable parts.

6. Selection and processing of injection mold processing mold materials.

7. Standardized production of molds: Try to choose standard templates, commonly used top rods, guide parts, gate bushings, positioning rings, and other standard products.

Basic composition of injection mold processing

1. Pouring system: The pathway through which molten material flows from the injection machine nozzle into the mold cavity, including the main flow path, diversion path, gate, cold well, drawing rod, etc.

2. Formed parts: parts of injection molded products, such as cores, cavities, and other auxiliary parts.

3. Temperature control system: used for temperature regulation of molds.

4. Formed product extrusion system: including side parting mechanism, secondary extrusion mechanism, several sequentially fixed distance parting mechanisms with first reset mechanism, etc.

5. Installation part: The part where the mold is reliably installed on the injection molding machine.

6. Connection system: A connection system that integrates various structures.

7. Guide system: Ensure the movement accuracy between the components of injection mold processing.
