Problems solved by technology

[0005] The feed port of the traditional injection head is directly connected to the discharge port of the horizontal pre-molding mechanism. The disadvantage is that the sealing performance of the connection surface, that is, the feed port, is not good, and material leakage is prone to occur.
In addition, the plasticized fluid material is easy to leak from the injection port, which brings unnecessary economic losses to the owner.

Abstract

The invention discloses an injection head for a horizontal plastic injection molding machine. The body of the injection head is provided with a feeding pore canal which is provided with a feeding port and an injection port; the body of the injection head is provided with a feeding connection part at the feeding port; the feeding connection part basically takes the shape of a semi-sphere groove with a concave sphere or a conical groove with a concave conical surface; the feeding port is arranged at the center of the feeding connection part at the feeding port. With good sealing function, the invention can prevent the leakage of the materials, thus the invention is widely applicable.

Description

technical field [0001] The invention belongs to the field of plastic injection molding machinery design, in particular to an injection nozzle and an injection head using the injection nozzle. Background technique [0002] Disc-type plastic injection molding machine is a kind of equipment specially used for manufacturing plastic soles. The discs used are often equipped with multiple sole molds of the same style and different sizes at the same time. Therefore, it is necessary to set the molds on the turntable for plastic The injection molding machine injects and molds molds with the same style and different code numbers in stages, and facilitates the process of opening the mold and taking out the molded sole. [0003] Disc plastic injection molding machines are generally divided into horizontal plastic injection molding machines and vertical plastic injection molding machines due to the different selection of pre-molding mechanisms. Horizontal plastic injection molding machine...
