The injection mold is a part that gives the plastic shape and size during the molding process. It is a high-temperature injection molding of the plastic raw material through the injection mold processed by the plastic product factory. Our common cosmetic packaging materials are also processed by cosmetic injection molding. Therefore, we have obtained different cosmetic packaging materials, such as lipstick tubes, lip gloss tubes, eye shadow boxes, powder boxes, mascara tubes, etc. In addition to cosmetic packaging materials, there are also plastic appliances, etc. Wait for the injection molded parts of our daily life manufacturers. Next, let’s analyze the introduction and composition of injection molds processed by plastic products factory

 

Precautions for mold design of plastic product factory's introduction to processing injection molds:

1. Determine the parting surface and gate location according to the use performance and molding performance of the plastic part.

2. Consider the manufacturability of the mold manufacturing project, determine the design plan according to the equipment status and technical strength, to ensure that the mold is easy to process from the whole to the parts, and it is easy to ensure the dimensional accuracy.

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

4. The size and structure of holes, pillars, convexities and concaves with precision requirements are displayed in the mold, that is, the plastic parts are not processed or processed less after being formed.

5. The mold structure strives to be simple and applicable, stable and reliable, with a short cycle and low cost, which is convenient for assembly, maintenance and replacement of wearing parts.

6. Selection and processing of mold materials.

7. Standardized production of molds: try to use standard mold bases, commonly used ejector pins, guide parts, sprue sleeves, positioning rings and other standard parts.

 

 

Basic composition of injection mold

1. Pouring system: the channel through which the molten material flows from the nozzle of the injection machine into the cavity, including the main flow channel, the runner channel, the gate, the cold slug well, the draw rod, etc.

2. Molded parts: parts of molded plastic parts, such as cores, cavities and other auxiliary parts.

3. Temperature control system: used to adjust the temperature of the mold.

4. Plastic parts ejection system: including side parting mechanism, secondary ejection mechanism, first reset mechanism and fixed distance parting mechanism.

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

6. Connection system: the connection system that combines the various structural parts into a whole.

7. Guiding system: to ensure the accuracy of the movement of each structural member, such as guide posts, guide chutes, etc.
