Description

An injection mold for rapid demoulding and removal of surface nozzle material

technical field

The utility model belongs to the technical field of injection moulds, and in particular relates to an injection mould, which can quickly demould and remove surface nozzle material.

Background technique

Mold: various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to shape an object. 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 article through the change of the physical state of the formed material. Known as the "Mother of Industry".

Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into the mold cavity to form when they are closed. The mold is a precision tool with a complex shape and bears the bulging force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing.

In the prior art, doll toys mainly use plastics as raw materials. During the demoulding operation, there are defects such as difficult demoulding, unbalanced demoulding, and easy damage to plastic products. The treatment of surface nozzle materials, these nozzle materials are used to inject liquid plastic seals during the injection molding process, and are formed by cooling after injection molding. For products made of plastic that are usually seen, the water outlet is usually cut manually. Manual operation is not only time-consuming, but also prone to fatigue, which will increase the cost of manpower; especially for mass production and processing, the efficiency of manual production If it is too low, it will eventually affect the progress of the entire production. In addition, the difference in manual processing is large, and the surface quality is difficult to maintain. Although it does not affect the overall appearance, it will reduce the consistency of the product as a whole, and The sharp tools used by manual handling can easily scratch the plastic products.
