[0021] The following will be combined with the appendix Figure 1 To be continued Figure 4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0022] This utility model provides a device for detecting the processing dimensions of refrigerator injection molded parts, including a workbench 1 and a refrigerator drawer 9. A U-shaped frame 2 is fixedly installed on the top of the workbench 1. An injection molding assembly is provided on the top of the workbench 1 and the top of the inner side of the U-shaped frame 2. A detection assembly is provided on the top of the workbench 1 and on the outer side of the U-shaped frame 2. A self-springing assembly is provided inside the injection molding assembly. Condensation assemblies are provided inside the workbench 1 and on both sides of the injection molding assembly. By providing the injection molding assembly, it is convenient to inject the molten material into the mold. By providing the self-springing assembly, it is convenient to pop out the molded refrigerator drawer 9 from the lower mold groove 6, preventing manual prying out with tools. By providing the condensation assembly, it is convenient to detect the molded refrigerator drawer 9. The molded refrigerator drawer 9 undergoes condensation to enhance its hardness. A detection component is installed to facilitate locking and locking of the popped-out drawer 9. If the dimensions of the drawer 9 match the space formed by the first L-shaped side panel 20 and the second L-shaped side panel 21, causing the drawer 9 to lock, it indicates that the dimensions of the drawer 9 are properly manufactured. If the dimensions do not match the space formed by the first L-shaped side panel 20 and the second L-shaped side panel 21, the drawer 9 will wobble. This prevents workers from experiencing eye strain when using tools to measure the four sides of the refrigerator injection molded parts, improving work efficiency, increasing the practicality of the equipment, and facilitating practical application and operation.
[0023] Furthermore, the injection molding assembly includes a cylinder 3, a connecting plate 4, an upper mold 5, and a lower mold groove 6. The cylinder 3 is fixedly installed on the top of the inner side of the U-shaped frame 2, the connecting plate 4 is fixedly installed on the piston rod of the cylinder 3, the upper mold 5 is fixedly installed on the bottom of the connecting plate 4, and the lower mold groove 6 is opened on the top of the worktable 1. By driving the cylinder 3, the upper mold 5 at the bottom of the connecting plate 4 is slowly moved closer to the lower mold groove 6, and the liquid material is squeezed and injected.
[0024] Furthermore, the condensation assembly includes a circular groove 10 and a condenser 11. The circular groove 10 is opened on both sides of the inner wall of the lower mold groove 6, and the condenser 11 is fixedly installed inside the circular groove 10. By driving the condenser 11 inside the circular groove 10, the refrigerator drawer 9 is condensed.
[0025] Furthermore, the self-elastic assembly includes a U-shaped box 7 and a first spring 8. The U-shaped box 7 is slidably connected inside the lower mold groove 6, and the first spring 8 is fixedly connected between the bottom of the U-shaped box 7 and the bottom of the inner wall of the lower mold groove 6. When the upper mold 5 disengages from the inside of the U-shaped box 7, the refrigerator drawer 9 inside the U-shaped box 7 is disengaged from the inside of the lower mold groove 6 by means of the elastic force of the first spring 8.
[0026] Furthermore, the detection assembly includes a slot 12, an L-shaped plate 13, a first push block 14, a second push block 15, a connecting rod 19, a first L-shaped side plate 20, a second L-shaped side plate 21, a slide 16, a second spring 17, and a slider 18. The slots 12 are all located on both sides of the inner wall of the U-shaped frame 2. The L-shaped plates 13 are all located on both sides of the injection molding assembly. The ends of the L-shaped plates 13 furthest from the injection molding assembly pass through the interior of the slots 12 and extend to the outside of the U-shaped frame 2. The second push blocks 15 are all slidably connected to the top of the workbench 1 and located on both sides of the U-shaped frame 2. The first push blocks 14 are all fixedly mounted. The first push block 14 and the second push block 15 are slidably connected, with the first push block 14 and the second push block 15 slidably connected. The connecting rods 19 are all fixedly installed on the inner side of the second push block 15. The end of the connecting rod 19 away from the second push block 15 passes through the interior of the U-shaped frame 2 and extends to the inner side of the U-shaped frame 2. The first L-shaped side plate 20 is fixedly installed on one end of one of the connecting rods 19, and the second L-shaped side plate 21 is fixedly installed on one end of the other connecting rod 19. The L-shaped plates 13 are all fixedly installed on both sides of the connecting plate 4. The sliding grooves 16 are all opened on the top of the workbench 1 and located on the second... Below the push block 15, the sliders 18 are slidably connected inside the slide groove 16. The second springs 17 are fixedly connected between one side of the inner wall of the slide groove 16 and one side of the inner wall of the slider 18. The bottom of the second push block 15 is fixedly connected to the top of the slider 18. When the connecting plate 4 moves upward from bottom to top, it drives the L-shaped plate 13 to move upward from inside the slot 12, thereby driving the first push block 14 to move upward. Utilizing the elasticity of the slide groove 16, it drives the slider 18 inside the slide groove 16 to slide, and drives the second push block 15 to move towards each other on the top of the worktable 1. The first L-shaped side plate 20 and the second L-shaped side plate 21 on the connecting rod 19 move towards each other, so that the inner sides of the second L-shaped side plate 21 and the first L-shaped side plate 20 come into contact with the perimeter of the refrigerator drawer 9. If the size of the refrigerator drawer 9 matches the space formed by the first L-shaped side plate 20 and the second L-shaped side plate 21, causing the refrigerator drawer 9 to be stuck, it indicates that the size of the refrigerator drawer 9 is qualified. If the refrigerator drawer 9 does not match the space formed by the first L-shaped side plate 20 and the second L-shaped side plate 21, the refrigerator drawer 9 will shake, thus achieving the detection effect.
[0027] Furthermore, the workbench 1 has a storage tank 22 inside, and the cylinder 3 and condenser 11 are electrically connected to the external control panel. By setting up the storage tank 22, it is convenient to store the processed refrigerator drawer 9. By setting up the electrical connection, the equipment can be driven more quickly.
[0028] The working principle of this utility model is as follows: First, the liquid material is injected into the U-shaped box 7. Then, the cylinder 3 is driven to slowly bring the upper mold 5 at the bottom of the connecting plate 4 closer to the U-shaped box 7 in the lower mold groove 6, and to squeeze and inject the liquid material, so that the U-shaped box 7 is squeezed into the lower mold groove 6, causing the first spring 8 to deform. Then, the condenser 11 in the circular groove 10 is driven to condense the refrigerator drawer 9. After the refrigerator drawer 9 has condensed, the cylinder 3 is driven to disengage the upper mold 5 at the bottom of the connecting plate 4 from the inside of the U-shaped box 7. At the same time, the elastic force of the first spring 8 is used to drive the U-shaped box 7 to slide upward in the lower mold groove 6, so that the refrigerator drawer 9 disengages from the lower mold groove 6. At the same time, when the connecting plate 4 moves from bottom to top, it drives the L-shaped plate 13 to move upward from the inside of the groove 12, thereby driving the first push block 14 to move upward. And the elastic force of the sliding groove 16 is used to drive the sliding groove 16 to move upward. The slider 18 inside slides, causing the second push block 15 to move towards each other on the top of the workbench 1. At the same time, it causes the first L-shaped side plate 20 and the second L-shaped side plate 21 on the connecting rod 19 to move towards each other, so that the inner sides of the second L-shaped side plate 21 and the first L-shaped side plate 20 contact the perimeter of the refrigerator drawer 9. If the size of the refrigerator drawer 9 matches the space formed by the first L-shaped side plate 20 and the second L-shaped side plate 21, causing the refrigerator drawer 9 to be stuck, it indicates that the size of the refrigerator drawer 9 is qualified. If the refrigerator drawer 9 does not match the space formed by the first L-shaped side plate 20 and the second L-shaped side plate 21, causing the refrigerator drawer 9 to shake, the detection is completed. Then, the cylinder 3 drives the connecting plate 4 to move down halfway, so that the second L-shaped side plate 21 and the first L-shaped side plate 20 no longer squeeze the perimeter of the refrigerator drawer 9. The worker can then take it out to complete the work.
