Description

Technical Field

[0001] The utility model relates to the technical field of processing molds, in particular to a secondary ejection mechanism of a processing mold for a washing machine frame. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is a tool that makes the blank into a part with a specific shape and size under the action of external force. It is widely used in the forming process of blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape. The use of a contour shape with a cutting edge can make the blank separate (punch out) according to the contour shape. The use of an inner cavity shape can make the blank obtain a corresponding three-dimensional shape. The mold generally consists of two parts: a movable mold and a fixed mold (or a convex mold and a concave mold), which can be separated or combined. When separated, the part is taken out, and when closed, the blank is injected into the mold cavity for forming.

[0003] After searching, the patent application number is (201721024746.1), which discloses a "secondary ejection mold", which solves the problem that the secondary ejection device itself is difficult to process and has high processing costs, resulting in high costs for the secondary ejection mold; moreover, in some secondary ejection molds, there is also the problem of low control accuracy of the two ejection distances of the secondary ejection device;

[0004] However, the above device has the following problems: Generally, when taking out the finished product from the mold, whether a single or multi-component ejection mechanism is used, the ejection action is completed once. However, due to the special shape of the finished product or the requirements of mass production, if the finished product is still in the mold cavity after one ejection or cannot fall off automatically, it is necessary to add another ejection action. Such an ejection action design is called secondary ejection. The secondary ejection mechanism of the existing plastic product processing mold has a complex structure, is inconvenient to use, and has a high mold manufacturing cost. For this reason, we propose a secondary ejection mechanism for a washing machine frame processing mold to solve the above problems. Utility Model Content
