Description

Technical Field

[0001] This utility model belongs to the field of wheel cover mold technology, and in particular relates to a pull-out locking wheel cover pressing mold. Background Technology

[0002] Wheel cover pressing molds are used to press metal sheets or blanks into the shape of wheel covers at room temperature. They belong to the category of cold stamping molds. In the pressing process, the metal sheet is first placed in the working area of ​​the lower mold. Then, the upper mold moves downward under the action of the press, contacts the lower mold and applies pressure to the sheet. The sheet undergoes plastic deformation under the action of the punch and die. Through deformation mechanisms such as shearing, bending and drawing, the required wheel cover shape is formed. After forming, the upper mold returns, and the unloading device and ejection device push the workpiece out of the mold, completing one stamping cycle.

[0003] When using wheel cover plate pressing molds, special clamps are used for fixation. By tightening the clamps on both sides, the mold is fixed. However, when using clamps to fix the mold, uneven force may occur. Uneven force during mold clamping and fixing can cause the mold to shift in position. Therefore, a pull-out locking wheel cover plate pressing mold is needed. This mold can be fixed through a fixing structure to avoid uneven force during mold clamping and fixing, thus ensuring the stability of the mold during fixing. Utility Model Content

[0004] The purpose of this invention is to provide a pull-out locking wheel cover plate pressing mold, which can be fixed by a fixing structure to avoid uneven force during mold clamping and fixation, and ensure the stability of the mold during fixation, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A pull-out locking wheel cover plate pressing mold includes slots opened on the front and back of the mold body. A mold base plate is provided at the bottom of the mold body. The mold base plate is located on the top of the press processing table. A mounting bracket is fixedly connected to the top of the mold base plate. The slots are adapted to the mounting bracket. Grooves are opened on both the front and back of the inner cavity of the mounting bracket. A limiting block is slidably connected to the inner cavity of the groove. The side of the limiting block near the mold body extends to the outside of the groove. A sliding rod is fixedly connected to the side of the limiting block away from the mold body. The end of the sliding rod away from the limiting block extends to the outside of the groove. A spring is sleeved on the surface of the sliding rod. A sliding groove is opened on the top of the mold base plate. A slider is provided in the inner cavity of the sliding groove. A threaded rod is rotatably connected to the inner cavity of the sliding groove. The threaded rod passes through the slider and is threadedly connected to the slider. One end of the threaded rod extends to the outside of the sliding groove and is fixedly connected to a torsion block. Two symmetrical openings are opened on both sides of the mold base plate.

[0006] Preferably, a fixing block is fixedly connected to the end of the slide bar away from the limiting block, and the fixing block is located outside the groove.

[0007] Preferably, the bottom of the mold body is in contact with the top of the mold base plate, and the side of the limiting block near the mold body is an inclined surface.

[0008] Preferably, one end of the spring is fixedly connected to the limiting block, and the other end of the spring is fixedly connected to the inner wall of the groove.

[0009] Preferably, the groove is an L-shaped groove, the slider is strip-shaped, and two symmetrical torsion bars are fixedly connected to the surface of the torsion block.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model involves placing the mold body into the inner cavity of the mounting frame, causing the limiting block to be squeezed into the inner cavity of the groove. At this time, the spring contracts. When the mold body is fully inserted into the inner cavity of the mounting frame, the spring expands, causing the limiting block to reach the right side of the mold body for limiting. By rotating the torsion block counterclockwise, the slider slides and fits against the right side of the mold body. This achieves the goal of fixing the mold through a fixed structure, avoiding uneven force during mold clamping and fixing, and ensuring the stability of the mold during fixing.

[0012] 2. By setting the inclined surface on the back of the limiting block, the limiting block will be squeezed into the inner cavity of the groove when the mold body extrudes the limiting block, thus avoiding the need for the user to pull the sliding rod to make the limiting block enter the inner cavity of the groove, and ensuring the fixed speed of the mold body.

[0024] Example 2:

[0025] Figure 1-5This invention illustrates a pull-out locking wheel cover pressing mold according to an embodiment of the present invention. It includes slots 4 formed on the front and back of a mold body 3. A mold base plate 2 is provided at the bottom of the mold body 3, located on the top of the processing table of a press 1. A mounting bracket 5 is fixedly connected to the top of the mold base plate 2. The slots 4 are adapted to the mounting bracket 5. Grooves 6 are formed on both the front and back of the inner cavity of the mounting bracket 5. A limiting block 7 is slidably connected to the inner cavity of the groove 6. The side of the limiting block 7 closest to the mold body 3 extends through to the outside of the groove 6. A sliding rod 8 is fixedly connected to the side of the limiting block 7 furthest from the mold body 3. The end of the sliding rod 8 furthest from the limiting block 7 extends through to... Outside the groove 6, a spring 9 is fitted on the surface of the slide bar 8. One end of the spring 9 is fixedly connected to the limiting block 7, and the other end of the spring 9 is fixedly connected to the inner wall of the groove 6.

Two symmetrical openings 14 are opened on both sides of the mold base plate 2.

[0026] Working principle: When using this utility model, the user places the mold body 3 into the inner cavity of the mounting bracket 5, causing the limiting block 7 to be squeezed into the inner cavity of the groove 6. At this time, the spring 9 will contract. When the mold body 3 is fully inside the inner cavity of the mounting bracket 5, the spring 9 will extend, causing the spring 9 to push the limiting block 7 to the outside of the groove 6, so that the limiting block 7 reaches the right side of the mold body 3 for limiting. Then, the torsion block 13 is rotated counterclockwise, causing the threaded rod 12 and the slider 11 to move threadedly. Through the limiting of the slide groove 10, the slider 11 slides and fits against the right side of the mold body 3 in the inner cavity of the slide groove 10 for limiting, avoiding uneven force when the mold is clamped and fixed, and ensuring the stability of the mold when fixed.

[0027] In summary: This pull-out locking wheel cover pressing mold, by placing the mold body 3 into the inner cavity of the mounting bracket 5, causes the limiting block 7 to be squeezed into the inner cavity of the groove 6. At this time, the spring 9 contracts. When the mold body 3 is fully inserted into the inner cavity of the mounting bracket 5, the spring 9 will expand, causing the limiting block 7 to reach the right side of the mold body 3 for limiting. By rotating the torsion block 13 counterclockwise, the slider 11 slides and fits against the right side of the mold body 3. This achieves the goal of fixing the mold through a fixing structure, avoiding uneven force during mold clamping and fixing, and ensuring the stability of the mold during fixing.
