Limiting device for injection mold processing

Abstract

The invention discloses a limiting device for injection mold processing. The device comprises a base ring arranged horizontally. The base ring is slidably provided with a plurality of frame plates. The frame plates are butted together to form a cylindrical structure. The cylindrical structure formed by the frame plates lacks an upper top surface. The inner wall of each frame plate is sealed and glued with a shaping capsule. The shaping capsule is a soft hollow capsule. A liquid storage cavity is arranged inside each frame. Sliding plates are sealed and slidably connected with the inside of theliquid storage cavities. The areas above the sliding plates in the liquid storage cavities and the inner of the shaping capsule are filled with magnetorheological fluid. The device has the advantagesthat after the shaping capsule is in good contact with a mold, a soft rod stops rotating and knocks on a slider, the internal pressure will push the slider to contact two electrical connection posts,a return spring and a solenoid coil are energized, the magnetorheological fluid becomes solid-like when feeling the magnetic field and cannot deform, thus the device can ensure a good clamping and limiting effect on the mold.

Description

technical field [0001] The invention relates to the technical field of interior decoration, in particular to a limiting device for injection mold processing. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. It is a method of injecting plastic materials into the mold cavity through high pressure at a certain temperature and cooling and solidifying to obtain molded products. It is widely used in shapes. The processing field of complex product forming. [0003] Injection mold is a tool for mass production of products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling, the molded product is obtained. ...

AI Technical Summary

Problems solved by technology

[0004] Injection molds are used for mass production of products, but the production of injection molds cannot rely on molds, and can only be processed by CNC machine tools or manual processing by staff. However, the price of injection molds in the prior art is difficult to limit, mainly because The shape of the mold varies greatly, and it is difficult to use any kind of fixture in the prior art to complete the limit. Therefore, we propose a limit device for injection mold processing that can be applied to various shapes
