Injection molding machine with safety device

Abstract

The invention discloses an injection molding machine with a safety device. The injection molding machine comprises a metal case, wherein support feet are arranged at four end corners of the bottom surface of the metal case; a rubber suction disc is arranged at the bottom end of each support foot; a hydraulic machine box is arranged above the metal case; a metal butting post is arranged at one sideof the hydraulic machine box; a safe material unloading device is arranged at the other side of the metal butting post; a cargo discharging cabin is arranged under the safe material unloading device;a buffer sponge pad is arranged at the inner wall of the cargo discharging cabin; a discharging opening is formed in the bottom end of the cargo discharging cabin; the discharging opening penetratesthrough the metal case and extends to the front end surface of the metal case; a female mold is arranged at the other side of the safe material unloading device; a cooling liquid pipeline is arrangedinside the female mold. A certain safe position limiting mechanism is installed; when a hydraulic rod is placed for a long time, the hydraulic rod exceeds the displacement, and accidents occur; the safety of the device is effectively improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to an injection molding machine with a safety device. Background technique [0002] With the rapid development of social economy, the use of plastic products has always been an indispensable product in people's lives. Injection molding machines are also known as injection molding machines or injection machines. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and make it inject and fill the mold cavity. The working principle of the injection molding machine is similar to that of a syringe for injection. It uses the thrust of the screw (or plunger) to push the plasticized plastic The process of injecting ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an injection molding machine with a safety device, to solve the problem that the existing injection molding machine proposed in the above background technology does not have a certain safety protection mechanism when the hydraulic cylinder is used for a long time and the hydraulic stepping degree is inaccurate.
