Automatic die switching device for injection molding machine

Abstract

The invention discloses an automatic die switching device for an injection molding machine. The device structurally comprises a die switching main machine, a base, a cabinet, a propeller, a feeding bucket, a feeding pipe and a die closing main machine, wherein the lower surface of the die switching main machine is fixedly mounted at one end of the base, and the base is integrally structured with the cabinet; the propeller is mounted at the other end of the base, and the lower end of the feeding bucket is mounted on the propeller; and the propeller is in end-to-end connection with the feeding pipe. According to the device, a rotary die switching mechanism is driven to switch dies through a power mechanism; the device is simple in structure, and simple and convenient to operate; the four sides of the dies are reinforced through a reinforcing mechanism, and clamping force is supplied to the four sides of the dies, so that the dies cannot be highly deformed and abraded during working; after being switched, the die to be put into work is cleaned through a dust removing mechanism, and thus the injection molding is performed on the die without any dust, and as a result, a finished productobtained by injection molding is free from impurities; the die after using can be cooled through a cooling mechanism, so that the die can be prevented from damage due to working under high temperature, and as a result, the service life of the die is prolonged.

Description

technical field [0001] The invention relates to the field of automatic mold changing devices for injection molding machines, in particular to an automatic mold changing device for injection molding machines. Background technique [0002] Injection molding machine, also known as injection molding machine, is the main molding equipment for making thermoplastics or thermoplastics into various shapes of plastic products with plastic molding molds. There are many shapes of molding, so there is a mold changer inside the equipment. device. [0003] However, the current automatic mold changing device has no clamping force around the mold, and only clamps the center of the back of the mold. In this way, the mold is deformed and worn during work. After the mold is changed, the dust on the mold is not cleaned before injection molding. As a result, the injection molded finished product is not clean, and the temperature inside the mold after switching is still high. If it is not cooled ...

[0003] However, the current automatic mold changing device has no clamping force around the mold, and only clamps the center of the back of the mold. In this way, the mold is deformed and worn during work. After the mold is changed, the dust on the mold is not cleaned before injection molding. As a result, the finished product of injection molding is not clean, and the internal temperature of the mold after switching is still very high. If it is not cooled in time, the service life of the mold will be reduced
