Injection molding machine convenient for mold replacement

Abstract

The invention discloses an injection molding machine convenient for mold replacement. The injection molding machine comprises a workbench, a protective cover and a movable cover. A rectangular through groove is formed between the two sides of one end of the workbench in a penetrating mode, a sliding groove is fixedly formed in the bottom face of the rectangular through groove, a motor placing plate is fixedly installed on the outer side of the sliding groove, a first motor is arranged on the upper surface of the motor placing plate, a screw is fixedly connected with one side of the first motor, the surface of the screw is in threaded connection with a sliding block, a movable plate is fixedly connected to the upper end face of the sliding block, the movable plate is fixedly connected to one end of the bottom of the protective cover, installation grooves are formed in the upper end and the lower end of the inner walls of the two sides of the protective cover, the movable cover is slidably connected with the installation grooves through installation sliding blocks arranged at the upper ends and the lower ends of the outer walls of the two sides. A pushing block is pushed and pulled through an air cylinder, the inserting position of a positioning bolt is adjusted under the cooperation of the sliding blocks and the sliding grooves, the effect of conveniently replacing a mold is achieved, molds of different sizes can be installed on the device, and the practicability of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to an injection molding machine for easy mold replacement. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. According to the arrangement of injection devices and clamping devices, it can be divided into vertical type, horizontal type and vertical-horizontal compound type. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and make it inject and fill the mold cavity. It usually consists of an injection system, a mold clamping system, a hydraulic transmission system, an electrical control system, a lubrication system, a heating and cooling system, and a safety monitoring system. composition. Among them, ...
