Embodiment 1

[0030] Such as figure 1 and figure 2 As shown, a quick mold opening and closing device in an injection molding machine includes a frame 1, an upper mold body 2, a lower mold body 3 and a driver 4, and the upper mold body 2 and the lower mold body 3 are connected to the frame 1. The upper and lower mold bodies 3 are located at the lower part of the upper mold body 2. After the upper mold body 2 and the lower mold body 3 are fastened, a molding cavity 5 with a cavity inside is formed between the two. The top of the frame 1 has a plate-shaped Connecting plate 6, on the connecting plate 6, there is a vertically arranged guide bar 7, the upper mold body 2 is connected on the guide bar 7, there is also a transition plate 8 between the upper mold body 2 and the driver one 4, and the driver one 4 is connected On the upper side of the transition plate 8, the transition plate 8 is fixedly connected with the drive part 2 9 and the drive part 9 is connected with the upper template. The ...

Embodiment 2

[0039] Such as image 3 The present embodiment shown is roughly the same as Embodiment 1, except that the driving part 2 9 is an oil cylinder, and the buffer structure is an air spring 16, the inner end of the air spring 16 is fixedly connected with the piston rod of the oil cylinder, and the outer end of the air spring 16 The end is fixedly connected with the upper mold body 2. Gas spring 16 is a kind of industrial accessory that can play functions such as support, cushioning, braking, height adjustment and angle adjustment, and can be purchased on the market, and it is more convenient and easy to replace.

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...
