Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a positioning fixture for mold processing. Background Technology

[0002] Mold processing refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. Positioning fixtures are often used in mold processing. When machining molds on machine tools, in order to ensure that the mold meets the technical requirements of dimensions, geometry, and relative positional accuracy with other surfaces specified in the drawings, the workpiece must be positioned and clamped before processing.

[0003] For example, Chinese utility model patent CN217702494U discloses a positioning fixture suitable for mold processing. Through the coordinated arrangement of an X-axis fixed positioning mechanism, an X-axis movable positioning mechanism, and a Y-axis movable positioning mechanism, it can be used to process molds of the same type but different sizes, improving the applicability of the fixture, saving time on fixture changes, increasing work efficiency, and improving labor productivity. However, this patent also has the following shortcomings: its applicability is limited; this positioning fixture is suitable for molds of the same type but different sizes, and its adaptability is low if the mold type is changed. Summary of the Invention

[0004] The present invention aims to address the shortcomings of the prior art by providing a positioning fixture for mold processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a positioning fixture for mold processing, comprising a base, a first annular groove on the top edge of the base, a sliding seat slidably mounted on the groove, a vertical slide table on the top of the sliding seat, an L-shaped support plate fixed on the slide plate of the slide table, an electric cylinder mounted on the support plate, a universal ball joint mounted on the piston rod end of the electric cylinder, a positioning push plate mounted on the universal ball joint, and a locking mechanism for locking the sliding seat on the top of the base.

[0006] Specifically, the horizontal edge of the support plate is provided with a pair of fixing blocks, which are fixedly connected to the electric cylinder.

[0007] In particular, the positioning push plate has an anti-slip pad on the side away from the electric cylinder.

[0008] Specifically, the bottom of the sliding seat is provided with a slider corresponding to the first sliding groove, and the slider is slidably disposed in the first sliding groove.

[0009] Specifically, the locking mechanism includes locking blocks on both sides of the sliding seat, with a clamping bolt threaded onto the locking block. A pressure plate is provided at the bottom of the clamping bolt, and a second sliding groove corresponding to the screw part of the clamping bolt and the pressure plate is provided at the top of the base. The screw part of the clamping bolt and the pressure plate are slidably disposed in the second sliding groove, and an anti-slip sleeve is provided on the nut of the clamping bolt.

[0010] The beneficial effects of this utility model are: by setting a circumferential sliding seat, locking mechanism, slide table, electric cylinder, universal ball head, and positioning push plate, this utility model facilitates the positioning and clamping of molds of different types and sizes, making the positioning operation convenient, highly flexible in use, and widely applicable.

[0016] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figures 1-4 As shown, a positioning fixture for mold processing includes a base 1. The top edge of the base 1 is provided with a first annular groove 2. A sliding seat 3 is slidably disposed on the groove 2. The bottom of the sliding seat 3 is provided with a slider 10 corresponding to the first groove 2. The slider 10 is slidably disposed in the first groove 2. The top of the base 1 is provided with a locking mechanism for locking the sliding seat 3. The locking mechanism includes locking blocks 11 disposed on both sides of the sliding seat 3. A clamping bolt 12 is threadedly connected to the locking block 11. A pressure plate 13 is provided at the bottom of the clamping bolt 12. The top of the base 1 is provided with a second groove 14 corresponding to the screw part of the clamping bolt 12 and the pressure plate 13. The screw part of the clamping bolt 12 and the pressure plate 13 are slidably disposed in the second groove 14. An anti-slip sleeve is provided on the nut of the clamping bolt 12.

[0019] The sliding seat 3 has a vertical slide table 4 at its top. An L-shaped support plate 5 is fixed on the slide plate of the slide table 4. An electric cylinder 6 is mounted on the support plate 5. A pair of fixing blocks 9 are provided on the horizontal edge of the support plate 5. The fixing blocks 9 are fixedly connected to the electric cylinder 6. A universal ball joint 7 is installed at the end of the piston rod of the electric cylinder 6. A positioning push plate 8 is provided on the universal ball joint 7. An anti-slip pad is provided on the side of the positioning push plate 8 away from the electric cylinder 6. The universal ball joint 7 allows the positioning push plate 8 to rotate freely within a certain range, thereby automatically adjusting the angle to fit the irregular surface of the mold. The structure is simple and flexible.

[0020] When this utility model is in operation, the mold to be processed is placed on the top of the base 1. The position of the sliding seat 3 is adjusted according to the mold type and specifications. Then, the clamping bolt 12 is rotated, the pressure plate 13 presses the second slide groove 14, the sliding seat 3 is locked, the slide table 4 is started, the electric cylinder 6 is adjusted to a suitable position, the electric cylinder 6 is started, and the positioning push plate 8 moves until it is in close contact with the mold. The universal ball head 7 is set so that the angle of the positioning push plate 8 can be adjusted to facilitate full contact with the mold. After the mold is positioned and clamped, subsequent processing can be carried out.

[0021] This utility model, by setting up a circumferential sliding seat, locking mechanism, slide table, electric cylinder, universal ball joint, and positioning push plate, facilitates the positioning and clamping of molds of different types and sizes. The positioning operation is convenient, the use is highly flexible, and the application range is wide.
