Rapid die opening and closing device in injection molding machine

Abstract

The invention provides a rapid die opening and closing device in an injection molding machine, belonging to the technical field of injection molding machines. The rapid die opening and closing device comprises a rack, an upper die body, a lower die body and a driving part I, wherein the upper die body and the lower die body are connected on the rack; the lower die body is arranged at the lower part of the upper die body; after the upper die body and the lower die body are fastened, a molding cavity with a cavity inside is formed between the upper die body and the lower die body; a connecting plate is arranged at the top of the rack; vertical guide rods are arranged on the connecting plate; the upper die body is connected on the guide rods; a transition plate is also arranged between the upper die body and the driving part I; the driving part I is connected with the upper side of the transition plate; a driving part II is fixedly connected on the transition plate and is connected with the upper die body; an injection molding opening communicated with the molding cavity is formed in the upper die body; and buffer structures are arranged between the driving part II and the upper die body. The rapid die opening and closing device not only is rapid in opening and closing and has high precision but also has the characteristics of reduction of the impact force and prolonging of service lives of parts.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an injection molding machine, in particular to a quick mold opening and closing device in the injection molding machine. Background technique [0002] With the development of industrial technology, high-end industrial production has gradually entered people's lives. The production and design of various designed products need to go through several steps such as drawing design, mold shaping and manufacturing. Injection mold is one of the most widely used molds in current industrial production, and it is a processing method used in mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. The injection mold consists of a moving mold and a fixed mold. The moving mold is installed on the movable template of the injection mo...

Problems solved by technology

However, this kind of existing injection mold has a slow speed when opening and closing the mold, which affects the output, and the speed is fast, the impact is large, the damage to the parts is large, the accuracy of the closing of the movable mold and the fixed mold is not high, and when the demoulding process Most of them require manual demoulding, which is not only labor-intensive, but also slow in production
