Description

Technical Field

[0001] This utility model relates to the field of plastic product deformation correction technology, and in particular to a product deformation correction fixture for die-cut hardware parts. Background Technology

[0002] In the production process of plastic molds, especially for products involving the molding of metal parts, product deformation is a common problem. Figure 5 As shown, this is a plastic-coated copper busbar made of PPS+GF20. During injection molding, it requires the use of copper hardware, which is only 0.5mm thick. The material is thin and soft. After injection molding, and left to stand naturally for 24 hours, the maximum deformation can reach 1.0–1.1mm (specifically, the center sags while the left and right ends bulge upwards). The general requirement is to control the deformation to within 0.30mm. This level of deformation far exceeds the acceptable range, rendering the product unusable and severely impacting product quality and production efficiency. Utility Model Content

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figures 1 to 5 As shown, this utility model provides a product deformation correction fixture for die-cut hardware parts. In one embodiment, it includes a base 1; a placement position 11 is provided on each of the two sides of the top of the base 1, and an isolation groove 12 is also provided between the two placement positions 11 on the top of the base 1; an adjustment block 13 is provided at each end of the placement position 11 (three adjustment blocks 13 are provided at each end of the placement position 11, the number of which depends on the product), and a support block 14 is arranged in the middle of the placement position 11; the height of the support block 14 is higher than the height of the adjustment block 13; a clamping and pressing mechanism is also installed at each end of the top of the base 1; each clamping and pressing mechanism includes two clamping and pressing components 2, and a pressing seat 3 connected to the two clamping and pressing components 2; the two clamping and pressing components 2 of each clamping and pressing mechanism are respectively arranged close to one end of a placement position 11, and the pressing seat 3 is arranged above the adjustment block 13.

[0022] Continue to refer to Figure 5As shown, this utility model addresses a plastic-coated large copper busbar, which is made of plastic, specifically PPS+GF20. During injection molding, it requires the use of copper hardware (0.5mm thick). However, due to the thinness and softness of the hardware, after the product is injection molded and left to stand naturally for 24 hours, the maximum deformation is 1.0-1.1mm (mainly sagging in the middle and arching upwards at both ends), exceeding the predetermined requirement that "the deformation of the product should be controlled within 0.30mm", rendering the product unusable.

[0023] Therefore, this correction fixture was designed. The fixture includes a base 1 made of aluminum alloy. The base 1 has two placement positions 11, which can correct two products at the same time, improving work efficiency. The height of the support block 14 in the middle of the placement position 11 is higher than the height of the adjustment blocks 13 located at both ends of the placement position 11. In this embodiment, the support block 14 is 1.0mm higher than the adjustment block 13 (set according to the deformation of the product). A clamping and pressing mechanism is installed at each end of the base 1 to press down the two ends of the product that are bulging upward due to deformation. At the same time, under the influence of the reaction force of the support block 14, the middle part of the product that is slumped up bulges upward, thereby adjusting and correcting the product deformation.

[0024] Meanwhile, a support strip 15 is arranged at one end of the support block 14 in the middle of the placement position 11 to support the middle of the product. A positioning pin 16 is installed at each end of the placement position 11. The support strip 15 is located between the two positioning pins 16. The positioning pins 16 are adapted to the positioning holes on the product to facilitate product positioning. When the fixture is opened, the positioning holes of the product are first aligned with the positioning pins of the fixture and inserted into the placement position 11 so that the middle of the product is placed on the support block 14. Then, the two ends of the product are pressed by the clamping seat 3 and the pressure correction time is 2 minutes (which can be determined according to the actual correction situation). If the injection molding production cycle is exceeded, one or more sets of correction fixtures need to be added, or the pre-pressure amount of the left and right adjustment blocks 13 needs to be increased to ensure the normal progress of injection molding production.

[0025] In one embodiment, the clamping and pressing assembly 2 includes a mounting base plate 21, a rotating rod, a linkage pressing rod 22, and a pressing rod; the rotating rod includes a rotating handle 23, and the bottom of the rotating handle 23 is connected to two opposing rotating connecting arms 24; the mounting base plate 21 is mounted on the top of the base 1, and a mounting vertical plate 25 extends upward from the middle of the top of the mounting base plate 21; the top of the mounting vertical plate 25 is provided with an inclined surface that slopes downward from one end to the other, and a first rotating shaft 26 is mounted at the shorter end of the mounting vertical plate 25, and a second rotating shaft 27 is mounted at the taller end of the mounting vertical plate 25; the two rotating connecting arms 24 are connected to the mounting vertical plate via the first rotating shaft 26. 25 Rotary connection; the pressing rod includes a pressing block 28, and one end of the pressing block 28 is also connected to two opposing pressing rotating arms 29; the two pressing rotating arms 29 are rotatably connected to the mounting vertical plate 25 via a second rotating shaft 27; the upper part of the linkage pressing rod 22 is rotatably connected to the inner wall of the two rotating connecting arms 24 via a third rotating shaft, and the lower part of the linkage pressing rod 22 is rotatably connected to the inner wall of the two pressing rotating arms 29 via a fourth rotating shaft; a pressing protrusion 20 extends outward from the side of the linkage pressing rod 22 near the pressing block 28, and the pressing protrusion 20 contacts the top of the pressing rod in the middle; a pressing connector is also installed on the pressing block 28, and the top of the pressing seat 3 is connected to the pressing connector.

[0026] After the product is placed on the placement position 11, the rotating rod can be manually rotated clockwise. As the rotating rod rotates, it will drive the linkage pressure rod 22 to rotate. During the rotation of the linkage pressure rod 22, the downward pressure protrusion 20 on one side of the linkage pressure rod 22 will gradually apply downward pressure to the downward pressure rod, thereby driving the downward pressure rotating arm 29 to rotate. When the downward pressure rotating arm 29 rotates, it will drive the downward pressure block 28 and the pressing seat 3 to press down, thereby pressing down the product.

[0027] Meanwhile, a limiting protrusion 251 is inclinedly provided on one side of the mounting vertical plate 25 near the first rotating shaft 26. The limiting protrusion 251 limits the rotational stroke of the rotating rod. Simultaneously, a first through hole 201 extending to the bottom of the lower pressure block 28 is provided at its top. The lower pressure connector includes a connecting seat 202 and a connecting screw 203 installed vertically on the connecting seat 202. A slot is provided on each side of the connecting seat 202, and the connecting seat 202 is engaged with the lower pressure block 28 via the slots. The connecting screw 203 passes through the first through hole 201, and the top of the pressing seat 3 is connected to the connecting screw 203. The connecting seat 202, engaged with the lower pressure block 28 via the slots, can slide relative to the lower pressure block 28, thereby allowing the position of the pressing seat 3 to be adjusted according to the actual usage scenario, meeting different usage needs and demonstrating strong practicality.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
