Description
Technical Field
The invention relates to the technical field of water cooling of injection molds, in particular to a cooling device for efficient injection mold production.
Background
Injection molding is a method for producing and molding industrial products. The products are generally produced by rubber injection molding and plastic injection molding. The injection molding can be classified into injection molding and die casting.
The main types of injection molding include:
1. rubber injection molding: rubber injection molding is a production method in which rubber is directly injected from a cylinder into a mold for vulcanization. The rubber injection molding has the advantages that: although the method is intermittent, the forming period is short, the production efficiency is high, the blank preparation procedure is cancelled, the labor intensity is low, and the product quality is excellent;
2, plastic injection molding: plastic injection molding is a method of producing plastic products by injecting molten plastic into a plastic product mold under pressure, and cooling and molding the plastic product to obtain various plastic parts. There are mechanical injection molding machines that are specifically used for injection molding.
The most commonly used plastics today are polyethylene, polypropylene, ABS, PA, polystyrene, etc.
3, molding and injection molding: the resulting shape is often the final product and no further processing is required prior to installation or use as the final product. Many details, such as bosses, ribs, threads, can be formed in a single injection molding operation.
Injection molding is accomplished by an injection molding machine and a mold. The mold mentioned therein is a tool for making shaped articles, which tool is composed of various parts, and different molds are composed of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material.
The die has a specific contour or cavity shape, and the blank can be separated (punched) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming. The die is a precise tool, has a complex shape, bears the expansion force of a blank, and has higher requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision.
When the mold is produced, the mold needs to be cooled to harden. But the moulds with a certain number occupy a certain area, and in the water cooling device, the cooling water is mostly sprayed at fixed points, so that the covered area is small; and for different amount of moulds, the heat quantity is different, thus the supply amount and the supply speed of cooling water are different, and the existing cooling liquid supply is inconvenient to control and cannot achieve better use effect.
Therefore, the inventor designs a cooling device for producing an efficient injection mold, which is used for solving the problems.
