Description

Technical Field

[0001] This utility model relates to the field of tooling and mold processing technology, specifically to a mold for improving the roundness of a stepped mold. Background Technology

[0002] In the field of electromechanical product manufacturing, insufficient roundness of the inner diameter of the casing has long been a technical problem. Traditional processing techniques are prone to causing excessive ellipticity due to stress deformation, resulting in a certain proportion of assembly interference problems during stator press-fitting. Therefore, there is an urgent need for an innovative method to control roundness from the source of processing in order to solve the problem of poor assembly. Utility Model Content

[0003] In view of the above-mentioned technical problems in related technologies, this utility model proposes a mold to improve the roundness of stepped molds, which can overcome the above-mentioned shortcomings of the prior art.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: A mold for improving the roundness of a stepped mold includes a frame. An oil cylinder is fixedly connected to the frame. The top of the oil cylinder is movably connected to a central rod via a piston rod. A workbench is located on the upper part of the frame. A fixed base is located in the middle of the workbench. The central rod passes through the fixed base and is connected to a petal mold. The petal mold is fitted onto the central rod. The petal mold includes a fixing part and a petal shape. The fixing part of the petal mold is fixedly connected to the fixed base. A stop is located at the top of the central rod that interacts with the top of the petal mold.

[0005] Furthermore, the side of the frame is provided with two-hand buttons for starting or stopping the hydraulic cylinder.

[0006] Furthermore, in use, the outer shell product is fitted onto the petal mold.

[0007] Furthermore, when the hydraulic cylinder drives the piston rod to move the central rod downward, the petal mold opens towards the inner wall of the opening of the outer shell product.

[0008] Furthermore, when the hydraulic cylinder drives the piston rod to move the central rod upward, the petal mold retracts towards the central rod.

[0009] Furthermore, the petal mold is matched with the outer shell product.

[0010] The beneficial effects of this utility model are as follows: By fitting a petal mold onto the central rod, the outer shell product is placed on the petal mold during use. The piston rod of the hydraulic cylinder drives the central rod to move upward, thereby causing the petal mold to open and making the opening of the outer shell product slightly larger. The overall structure is simple and easy to operate. It improves the roundness of the product from the processing source and has great practical value. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0014] like Figure 1-2 As shown, a mold for improving the roundness of a stepped mold according to an embodiment of the present invention includes a frame. An oil cylinder 8 is fixedly connected to the frame. The top of the oil cylinder 8 is movably connected to a central rod 1 via a piston rod 7. An equipment workbench 5 is provided on the upper part of the frame. A fixed base 4 is provided in the middle of the equipment workbench 5. The central rod 1 passes through the fixed base 4 and is connected to a petal mold 3. The petal mold 3 is fitted onto the central rod 1. The petal mold 3 includes a fixing part and a petal mold. The fixing part of the petal mold 3 is fixedly connected to the fixed base 4. A stop is provided on the top of the central rod 1 that interacts with the top of the petal mold.

[0015] In this embodiment, the side of the frame is provided with two-hand buttons 6 for starting or stopping the hydraulic cylinder 8.

[0016] In this embodiment, when in use, the outer shell product 2 is fitted onto the petal mold 3.

[0017] In this embodiment, when the hydraulic cylinder 8 drives the hydraulic cylinder piston rod 7 to move the central rod 1 downward, the petal mold opens towards the inner sidewall of the opening of the outer shell product 2.

[0018] In this embodiment, when the hydraulic cylinder 8 drives the hydraulic cylinder piston rod 7 to move the central rod 1 upward, the petal mold retracts towards the central rod 1.
