Problems solved by technology

[0002] At present, the molding molds of injection molding machines are generally equipped with vent holes to facilitate natural exhaust during mold closing and injection. After the injection molded parts in the molding mold are finalized, the air in the molding mold is small to form a negative pressure, which is not easy to open the molding mold.

Embodiment Construction

[0013] The features of the present invention and other relevant features are described in further detail below through the embodiments, so as to facilitate the understanding of those skilled in the art:

[0014] Such as figure 1 As shown, a control system for pumping and supplying air to the mold of an injection molding machine includes a control module 1, a pressure-resistant container 2 for buffering gas, and a three-port communication pipe 3 with one port connected to the air hole on the molding mold of the injection molding machine. Between the second port of the three-port communicating pipe 3 and the pressure-resistant container 2, a first electromagnetic valve 4, a vacuum generator 5 for evacuating the mold of the injection molding machine, and a second electromagnetic valve are arranged in sequence. Valve 6, a third solenoid valve 7 for controlling the gas in the pressure-resistant container 2 to be sent back to the mold of the injection molding machine is provided bet...

Abstract

The invention discloses an air suction and air supply control system for an injection molding machine molding die. According to the air suction and air supply control system for the injection moldingmachine molding die, a three-port communicating pipe is adopted to be connected with an air hole in the injection molding machine molding die, namely, the air suction and the air supply share the samethree-port communicating pipe, and the three-port communicating pipe is convenient to connect and use; a control module, through controlling a first electromagnetic valve, a vacuum generator, a second electromagnetic valve and a third electromagnetic valve, is used for temporarily storing air in the injection molding machine molding die in a pressure-resistant container during an air suction process and used for sending the air temporarily stored in the pressure-resistant container back into the injection molding machine molding die during an air supply process, and the control is convenient;and when the air temporarily stored in the pressure-resistant container is sent back into the injection molding machine molding die, the air pressure in the injection molding machine molding die cannot be too large, so that pressure maintaining, shaping and subsequent opening of the injection molding machine molding die are facilitated.

Description

[technical field] [0001] The invention relates to an air extraction control system for molding molds of injection molding machines. [Background technique] [0002] At present, the molding molds of injection molding machines are generally equipped with vent holes to facilitate natural exhaust during mold closing and injection. When the injection molded parts in the molding mold are finalized, the air in the molding mold is small to form a negative pressure, which is not easy to open the molding mold. [0003] Therefore, how to overcome the above existing defects has become an important issue to be solved urgently by those skilled in the art. [Content of the invention] [0004] The present invention overcomes the disadvantages of the above-mentioned technologies, and provides an air extraction and air supply control system for molding molds of injection molding machines, which is convenient for mold clamping and opening of molding molds for injection molding machines. [00...
