Double-color hot runner die and using method thereof

Abstract

The invention discloses a double-color hot runner die and a using method thereof. The double-color hot runner die comprises thimbles, a positioning round pin, a rear die insert, a rear die, a guide sleeve, an upper guide post, a front die, a front die insert, a hot runner, a pouring gate, a movable die and a cylinder. A double-color die product is generated by one-time stripping in the hot runner die. After the die is closed for casting in use, the die is opened, the runner rest in a semi-finished product is ejected, then the movable die rotates for 180 degrees, the die is closed again for casting, the die is opened, the runner rest and the finished product in the semi-finished product are ejected by the left and right thimbles respectively, and then the die is closed for processing the products of next batch. The double-color hot runner die has the advantages of high automation degree, high production efficiency, low requirement for operators and simplicity in processing; and the cost is reduced due to large production batch, the appearance of the produced product is attractive, the reject rate is reduced, the quality of the product is improved, the plastic raw material is saved, and subsequent processes are not needed.

Description

technical field [0001] The invention relates to a two-color hot runner mold and a use method thereof, which can meet the processing requirements of one-time ejection of the two-color mold. Background technique [0002] In the production process of injection molded products, injection molds are currently widely used. Due to technical limitations, most of the previous mold products were produced in one color, that is, only one plastic material could be used for injection molding, so the appearance of the products produced in this way was not rich enough in terms of material and color. With the development of the times, people now have higher and higher requirements for the appearance of products, and the pursuit of more exquisite, fashionable and personalized mold products has become a current trend. [0003] At present, two-color molds are becoming more and more popular in the market, but there are also disadvantages of complex molds and high processing costs. For two-colo...

AI Technical Summary

Problems solved by technology

Therefore, the whole production process is more complicated, and there are many processes, which leads to the reduction of mold precision.

Moreover, the two-color mold generally has the phenomenon that the product is loose or peeled off from the staying side of the mold after the first molding, resulting in defective products or mold damage caused by the second molding
