Because plastic products are usually produced in bulk or in large quantities, 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 processing based on the usage and molding performance of the molded product.

2. Considering the processability of the mold manufacturing process, the design scheme 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. Considering the productivity of injection mold processing, increasing the number of injections per unit time and shortening the molding cycle.

4. Show the required precision dimensions and structures such as holes, columns, protrusions, and indentations on the mold. That is to say, the molded product should not be processed or machined after molding.

5. The mold structure aims for simple application, stability, reliability, short cycle, low cost, and easy assembly, repair, and replacement of vulnerable parts.

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

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

The basic components 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, sprue, cold material well, drawing rod, etc.

2. Shaped parts: Parts that are processed into molded products using injection molds, such as cores, cavities, and other auxiliary parts.

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

4. Extrusion system for molded products: including side parting mechanism, secondary extrusion mechanism, and several sequential distance parting mechanisms such as reset mechanism.

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

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

7. Guide system: Ensure the precision of movement between the various components of the injection mold during processing.
