Displacement device for injection mold

Abstract

The utility model relates to a shifting device for an injection mold, which belongs to the technical field of injection molds and comprises a fixing frame, a slider and a telescopic mechanism. The sliding block slides in the long-strip-shaped sliding hole. The telescopic mechanism is fixed to the bottom end of the fixing frame, the telescopic end of the telescopic mechanism stretches out and draws back in the length direction of the long-strip-shaped sliding hole in a reciprocating mode, and the telescopic end of the telescopic mechanism is fixed to the sliding block so as to push the sliding block to slide in the length direction of the long-strip-shaped sliding hole in a reciprocating mode. The telescopic mechanism originally fixed at the rear end of the fixing frame is fixed at the bottom end of the fixing frame, so that the structural strength of the shifting device can be enhanced, the size of the shifting device can be reduced, and the application range of the injection mold can be expanded.

Description

TECHNICAL FIELD

[0001] The utility model relates to injection mold technical field, especially injection mold is with displacement device. BACKGROUND

[0002] Injection mold is a tool for producing plastic products, and is also a tool for giving plastic products complete structure and accurate size. Injection molding is a processing method used when mass producing some complex-shaped parts, specifically referring to injecting high-pressure molten plastic into a mold cavity by an injection molding machine, and obtaining a shaped product after cooling and solidification.

[0003] At present, the displacement device for injection mold mainly comprises a fixing frame, a sliding block and an oil cylinder, the fixing frame is provided with a long sliding hole and a through hole at the rear end thereof; the sliding block slides in the long sliding hole; the oil cylinder is fixed at the rear end of the fixing frame, and the piston rod of the oil cylinder reciprocates along the length direction of the long sliding hole through the through hole; the above structure can push the sliding block to reciprocate, but the oil cylinder is fixed at the rear end of the fixing frame, which greatly increases the volume of the whole device and limits the use scene of the injection mold.

[0004] Therefore, how to design a displacement device for injection mold, which is stable in operation, small in volume and high in structural strength, is a problem to be solved by those skilled in the art. CONTENT OF THE UTILITY MODEL

[0005] The utility model provides a displacement device for injection mold, which solves the technical problem of large volume of the existing displacement device for injection mold.

[0006] The technical scheme for solving the above technical problem is as follows: a displacement device for injection mold comprises a fixing frame, a sliding block and an extension mechanism,

[0007] The fixing frame is provided with a long sliding hole; the sliding block slides in the long sliding hole; the extension mechanism is fixed at the bottom end of the fixing frame and reciprocates along the length direction of the long sliding hole, and the extension end of the extension mechanism is fixed on the sliding block to push the sliding block to reciprocate along the length direction of the long sliding hole.

[0008] The utility model has the advantages that the structure of the traditional displacement device for injection mold is improved, the extension mechanism originally fixed at the rear end of the fixing frame is fixed at the bottom end of the fixing frame, the structural strength of the displacement device is enhanced, the volume of the displacement device is reduced, and the application range of the injection mold is expanded.

[0009] On the basis of the above technical scheme, the utility model can also be improved as follows.

[0010] Further, the bottom end of the fixing frame is provided with a mounting groove, and the extension mechanism is embedded in the mounting groove.

[0011] The further beneficial effect is that the telescopic mechanism is embedded in the mounting groove at the bottom end of the fixed frame, which can further reduce the volume of the displacement device and expand the application range of the injection mold.

[0012] Further, the telescopic mechanism is a pneumatic cylinder, an oil cylinder or an electric telescopic rod. BRIEF DESCRIPTION OF DRAWINGS
