Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a plastic product processing mold with a sliding positioning structure. Background Art

[0002] Processing plastic products through molds is a common processing method. For the processing of snap positions or side concave positions on plastic products, a sliding processing structure needs to be designed. When the mold is closed, the sliding processing structure slides out to process the snap position or side concave position. When the mold is opened, the sliding processing structure should automatically retract to ensure the smooth demolding of the product. The sliding processing structure in the existing mold has no positioning device, and the stroke accuracy of the sliding processing structure cannot be guaranteed, resulting in the inability to guarantee the processing accuracy of the snap position or side concave position of the product.

[0003] A patent with the publication number of CN220242272U discloses a plastic product processing mold with a sliding positioning structure, belonging to the technical field of mold devices. A wear-resistant bottom plate is provided on the mold base of the lower mold. A spring is provided in the accommodating cavity of the mold base. A positioning pin is provided at the top of the spring. The top of the positioning pin penetrates through the wear-resistant bottom plate. The top end of the positioning pin is a triangular positioning end. The bottom of the slider seat is slidably connected to the wear-resistant bottom plate. Several triangular grooves cooperating with the triangular positioning end are provided on the lower surface of the slider seat. A processing part is provided on the side of the slider seat. An inclined driving long hole is formed on the slider seat. An inclined driving column is detachably inserted and matched with the driving long hole. The top of the driving column is fixed on the pressing block, and the pressing block is fixed on the upper mold. The beneficial effect of the utility model is that: through the cooperation of the positioning pin and the two triangular grooves, the moving stroke of the processing part is positioned to ensure that it moves in place, thereby ensuring the product processing quality.

[0004] Although the above device solves the problem that the sliding processing structure in the existing mold has no positioning device and the stroke accuracy of the sliding processing structure cannot be guaranteed, resulting in the inability to guarantee the processing accuracy of the snap position or side concave position of the product, the distance between the two triangular grooves of the above device is fixed and only suitable for processing one kind of processing part. When different processing parts need to be processed, the entire slider seat needs to be replaced, and the replacement cost is relatively high. Therefore, a plastic product processing mold with a sliding positioning structure is proposed for the above problems. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology and solve the problem that the distance between the two triangular grooves of the existing device is fixed and only suitable for processing one kind of processing part, and when different processing parts need to be processed, the entire slider seat needs to be replaced, and the replacement cost is relatively high, the utility model proposes a plastic product processing mold with a sliding positioning structure.

During use, the first block and the second block are combined together to form a complete slider seat through the connecting component. Additionally, multiple second blocks are reserved, and the positions of the two triangular positioning grooves at the bottom of the second block are different. When different workpieces need to be processed, the second block can be quickly disassembled through the connecting component to replace different second blocks. Since the positions of the two triangular positioning grooves at the bottom of the second block are different, accurate positioning can be achieved when processing different workpieces, and it is not necessary to replace the entire slider seat, thus saving costs.

[0017] 2. The utility model is provided with structures such as a baffle, a limiting guide rail, a movable block, an inserting block and a slot. During use, first slide the movable block and the inserting block upward, and then insert the limiting guide rail into the limiting groove until the second block abuts against the baffle.

The top of the connecting block 5 is fixedly connected with a positioning pin 6. The positioning pin 6 penetrates and extends outside the sliding cavity, and the top end of the positioning pin 6 is adapted to the positioning groove 7. The top ends of the positioning groove 7 and the positioning pin 6 are triangular; During work, such as Figure 2As shown in the figure, the triangular positioning groove 7 on the left is used to position the slider seat 2 after mold clamping. After mold clamping, the triangular top end of the positioning pin 6 is located at the triangular positioning groove 7 on the left, enabling the slider seat 2 to be accurately positioned after mold clamping. Furthermore, the position of the workpiece can be accurately determined, ensuring the qualification rate of the processing of the snap position or side concave position on the product. The triangular positioning groove 7 on the right is used to position the slider seat 2 after mold opening. After mold opening, the triangular top end of the positioning pin 6 is located in the triangular positioning groove 7 on the left, enabling the slider seat 2 to be accurately positioned after mold opening. In addition, by setting the connecting component, the block one 21 and the block two 22 are combined to form a complete slider seat 2. Additionally, multiple block twos 22 are reserved, and the positions of the two triangular positioning grooves 7 at the bottom of the block two 22 are different. When different workpieces need to be processed, the block two 22 can be quickly disassembled through the connecting component to replace different block twos 22.
