Ejection forming device and its method

Abstract

An emission forming device is used to form an emission forming material to a finished product. It contains a die unit, an emission unit and a humidifying unit. The die unit has a die point. The emission unit has a nozzle. The nozzle locates on one side of the way pipe and connects it with the die point. The humidifying unit is adjacent to the die unit for providing moisture. The emission forming materials enter the nozzle through the way pipe to jet into the die point and form the finished products by cooling. The materials separate from the die unit to make the humidifying unit providing moisture for the finished products.

Description

technical field [0001] The present invention relates to an injection molding device and its method, in particular to an injection molding device and its method which can solve the problem of silver marks. Background technique [0002] With the development of human material civilization, the method of using molds to manufacture products has become an indispensable technology for life. At present, the methods of using molds to manufacture products are mainly divided into injection molding, compression molding, blow molding and foam molding, etc. Among them, injection molding has the advantages of short manufacturing time, complex shapes and low prices, and has gradually become an unavailable Alternative manufacturing techniques. [0003] Please refer to FIG. 1a and FIG. 1b . FIG. 1a and FIG. 1b are known injection molding devices 1 . The known injection molding method is described below using FIG. 1a and FIG. 1b . First, a plastic material is poured into a feed port 11 for d...

Problems solved by technology

[0004] However, since the traditional injection molding factory is usually a workplace with high relative humidity (70%RH~95%RH), and the injection environment of the traditional injection molding factory is often dusty, when the molded product after injection molding is dry and moisture-free, Molded products tend to absorb moisture and dust mixed in the air through capillary phenomenon, resulting in a lot of dirt and traces (commonly known as silver marks in the industry) in the molded products, which will affect the subsequent surface processing and lead to a decrease in product yield

[0005] This shows that above-mentioned existing injection molding device and method thereof obviously still have inconvenience and defect in structure and use, and urgently need to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
