Description

Technical Field

In addition, the processing precision of automotive parts is high, and the requirements for automotive molds are also relatively higher.

[0003] Existing automobile molds are prone to deviation during operation, causing errors between the upper and lower molds during the mold closing process, thereby affecting the quality of automobile parts after molding. Therefore, we propose a positioning device for automobile molds to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a positioning device for an automobile mold, which is used to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, the multiple inclined grooves in the positioning groove are respectively located on the inner walls of the four sides, and the inclined grooves are arranged at an angle to facilitate the rollers on the positioning block to abut against the corresponding inclined grooves, thereby achieving position correction of the positioning block that has produced positional displacement.

[0008] Preferably, the multiple wheel grooves in the positioning groove are respectively located on the inner walls of the four sides, and the wheel grooves are located directly below the corresponding inclined grooves, so that the multiple rollers on the positioning block can slide into the corresponding wheel grooves respectively.

[0009] Preferably, the upper die is located above the lower die, and the upper die is matched with the lower die.

[0010] Preferably, the two positioning blocks on the bottom side of the upper mold are symmetrically arranged, and the positioning blocks are adapted to the positioning grooves, so that the two positioning blocks can be inserted downward into the corresponding positioning grooves to achieve the clamping of the upper mold and the lower mold.

[0011] Preferably, the rolling mechanism includes a mounting groove and a roller. A mounting groove is opened on one side wall of the slope. A roller is rotatably installed in the mounting groove. The roller is adapted to the wheel groove. When the corresponding roller on the positioning block overlaps the corresponding inclined groove, as the upper mold and the two positioning blocks continue to move downward, the position of the positioning block that has been offset is corrected.

[0012] Preferably, the bottom side of the roller is level with the bottom side of the positioning block, and one side of the roller slightly exceeds the side of the positioning block, so that when the upper mold is offset during the downward movement, the corresponding roller on the positioning block can overlap the corresponding inclined groove.

[0013] The beneficial effect of the utility model is that the positioning device for automobile mold drives the upper mold and the two positioning blocks to move downward by opening the hydraulic rod. When the upper mold is offset during the downward movement, the rollers in the installation grooves on the corresponding slope side will overlap the corresponding inclined grooves. As the upper mold and the two positioning blocks continue to move downward, the positions of the positioning blocks with position offset are corrected, so that the multiple rollers on the two positioning blocks slide into the corresponding wheel grooves respectively, so that the two positioning blocks are smoothly inserted into the corresponding positioning grooves, and auxiliary positioning is realized, which reduces the offset generated in the process of closing the upper mold and the lower mold, thereby ensuring the stable molding of automobile parts.

There are two positioning blocks 10, and a plurality of slopes 11 are respectively provided on the bottom sides of the positioning blocks 10. A rolling mechanism for the wheel groove 5 is arranged on the slope 11. The rolling mechanism includes a mounting groove 12 and a roller 13. A mounting groove 12 is provided on one side wall of the slope 11. A roller 13 is rotatably installed in the mounting groove 12. The roller 13 is adapted to the wheel groove 5. When the corresponding roller 13 on the positioning block 10 overlaps the corresponding inclined groove 4, as the upper mold 9 and the two positioning blocks 10 continue to move downward, the position of the positioning block 10 that has produced a position shift is corrected.

[0020] Furthermore, the multiple inclined grooves 4 in the positioning groove 3 are respectively located on the inner walls of the four sides, and the inclined grooves 4 are arranged at an angle to facilitate the rollers 13 on the positioning block 10 to abut against the corresponding inclined grooves 4, thereby realizing position correction of the positioning block 10 that has produced positional displacement.

[0021] Furthermore, the multiple wheel grooves 5 in the positioning groove 3 are respectively located on the inner walls of the four sides, and the wheel grooves 5 are located directly below the corresponding inclined grooves 4, so that the multiple rollers 13 on the positioning block 10 can slide into the corresponding wheel grooves 5 respectively.

[0022] Furthermore, the upper die 9 is located above the lower die 2 , and the upper die 9 is matched with the lower die 2 .

[0023] Furthermore, the two positioning blocks 10 on the bottom side of the upper mold 9 are symmetrically arranged, and the positioning blocks 10 are adapted to the positioning grooves 3, so that the two positioning blocks 10 can be inserted downward into the corresponding positioning grooves 3 to achieve the clamping of the upper mold 9 and the lower mold 2.

[0024] Furthermore, the bottom side of the roller 13 is kept level with the bottom side of the positioning block 10, and one side of the roller 13 slightly exceeds the side of the positioning block 10. When the upper mold 9 is offset during the downward movement, the corresponding roller 13 on the positioning block 10 will overlap the corresponding inclined groove 4.

[0025] During use: by opening the hydraulic rod 8, the upper mold 9 and the two positioning blocks 10 are driven to move downward. When the upper mold 9 is offset during the downward movement, the roller 13 in the mounting groove 12 on the side of the corresponding slope 11 will overlap the corresponding inclined groove 4. As the upper mold 9 and the two positioning blocks 10 continue to move downward, the position of the positioning block 10 with position offset is corrected, so that the multiple rollers 13 on the two positioning blocks 10 slide into the corresponding wheel grooves 5 respectively, so that the two positioning blocks 10 are smoothly inserted into the corresponding positioning grooves 3, to achieve auxiliary positioning, reduce the offset generated during the clamping process of the upper mold 9 and the lower mold 2, and thus ensure the stable molding of automobile parts.
