Feeding device of open-type injection molding machine

Abstract

The invention relates to a feeding device of an open-type injection molding machine, comprising a template and an injection molding device, wherein the template is provided with a mould; a feeding hole is arranged in the template and is matched with an injection molding head of the injection molding device; the injection molding head is connected with a storage cylinder; a prepush device and the injection molding device are arranged in the storage cylinder; and the storage cylinder is connected with a charging barrel. The feeding device is characterized in that the mouth of the storage cylinder is provided with an opening connected with a feeding hopper; the inlet of the feeding hopper is in contact with the outlet of the charging barrel; the bottom surface of the feeding hopper is provided with an electronic scale, or the inner wall of the feeding hopper is provided with an optoelectronic switch; and the feeding hopper is provided with a blanking device. With technical scheme, the invention has the advantages that the charging barrel continuously works and blanks, and the feeding device has high feeding speed, high production efficiency, simple structure and easy connection.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to an open feeding device for an injection molding machine, which is mainly suitable for producing thin products such as wood-plastic boards. Background technique [0002] When the existing injection molding machine is working, the power drives the screw to rotate in the barrel, and at the same time heats the material, extrudes the material from the barrel into the mold, and finally injects it into the mold. Otherwise, there is no place for the material to be stored, so the processing speed is slow; and the screw must be retreated, resulting in a long distance between the two ends of the barrel, a large volume, a large space occupation, and an increase in cost. Therefore, the inventor once designed a kind of "injection molding material storage device for injection molding machine", which mainly includes connecting a storage tank on the injection molding head. The pre-push device and ...

Problems solved by technology

[0002] When the existing injection molding machine is working, the power drives the screw to rotate in the barrel, and at the same time heats the material, extrudes the material from the barrel into the mold, and finally injects it into the mold. Otherwise, there is no place for the material to be stored, so the processing speed is slow; and the screw must be moved back, resulting in a long distance between the two ends of the barrel, a large volume, a large space occupation, and an increase in cost

However, in actual production, since the material inlet is made on the side wall of the storage tank, the size of the material inlet is limited, so that the material in the material barrel cannot quickly enter the storage tank, which affects the processing speed. And the barrel is connected on the wall of the barrel, the installation is troublesome and the structure is complicated
