Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a refrigerator door model stamping device. Background Technology

[0002] Refrigerator models are prototypes used by manufacturers to showcase or study the appearance or internal structure of refrigerators. When manufacturing the door shell of a refrigerator model, sheet metal parts need to be shaped using stamping dies. Existing stamping dies only have ejection devices in the upper or lower die, as disclosed in patent documents such as CN111054825A and CN210023484U. Since the edges of the door shell need to be flanged, and the flanged area contacts both the upper and lower dies, this die structure, with an ejection mechanism only on one side, easily leads to difficulty in demolding the other half of the die without an ejection mechanism. This causes the demolded door shell to deviate from the robot's pick-up position, requiring improvement. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a refrigerator door model stamping device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A refrigerator door model stamping device includes a stamping die, which includes an upper die base and a lower die base arranged vertically. Upper connecting blocks are connected to the bottom sides of the upper die base, and the bottoms of the two upper connecting blocks are connected to the upper die. A plurality of ejector rods are longitudinally threaded inside the upper die. Anti-detachment rings are fixedly sleeved on the upper parts of the ejector rods, and an elastic element abuts against the anti-detachment rings and the upper die base. Lower connecting blocks are connected to the top sides of the lower die base, and a support plate is connected to the top of the two lower connecting blocks. A lower die is fixedly connected to the top of the support plate. A receiving groove is formed on the top surface of the lower die, and a top block is fitted into the receiving groove. A connecting rod is fixedly connected to the bottom of the top block, and the connecting rod longitudinally penetrates the lower die and the support plate. A telescopic cylinder is longitudinally installed on the top of the lower die base, and the telescopic end of the telescopic cylinder is connected to the connecting rod.

[0006] Furthermore, the upper mold is a concave mold, the lower mold is a convex mold, the upper mold and the lower mold cooperate with each other, when the anti-detachment ring abuts against the top surface of the upper mold, the ejector rod protrudes from the bottom surface of the upper mold, and the telescopic cylinder can lift the top block upward.

[0007] Furthermore, the elastic element is a compression spring, and one end of the compression spring is sleeved on the top of the ejector rod.

[0008] Furthermore, it also includes a stamping machine, which includes a top plate and a mounting platform arranged vertically, the top plate and the mounting platform being fixed relative to each other, the lower die holder being fixed to the top of the mounting platform, a hydraulic cylinder being longitudinally mounted on the top plate, and the upper die holder being fixed to the telescopic end of the hydraulic cylinder.

[0009] The beneficial effects of this utility model are as follows: the upper mold and the lower mold move towards each other, which can stamp and shape the refrigerator door shell between them. After stamping, during the upward movement of the upper mold, the ejector rod, under the action of the elastic element, always presses the refrigerator door shell onto the lower mold, so that the refrigerator door shell can be smoothly removed from the upper mold. After the ejector rod leaves the refrigerator door shell, the ejector block is driven to move upward by the telescopic cylinder, so that the refrigerator door shell can be smoothly removed from the lower mold. This eliminates the problem of unsuccessful demolding and ensures that the demolded refrigerator door shell is located in the correct part removal position. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0013] like Figure 1As shown, a refrigerator door model stamping device includes a stamping die and a stamping machine. The stamping machine includes a top plate 1 and a mounting platform 2 arranged vertically. The top plate 1 and the mounting platform 2 are fixed relative to each other. A hydraulic cylinder 3 is longitudinally mounted on the top plate 1, with the telescopic end of the hydraulic cylinder 3 facing the ground. The stamping die includes an upper die base 4 and a lower die base 5 arranged vertically opposite to each other. The upper die base 4 is fixed to the telescopic end of the hydraulic cylinder 3, and the lower die base 5 is fixed to the top of the mounting platform 2. Upper connecting blocks 41 are connected to the left and right sides of the bottom of the upper die base 4. The bottom of the two upper connecting blocks 41 are connected to an upper mold 6. Two ejector rods 7 are longitudinally inserted inside the upper mold 6. An anti-detachment ring 71 is fixedly sleeved on the upper part of the ejector rod 7. An elastic element 8 is abutted between the anti-detachment ring 71 and the upper die base 4. Specifically, the elastic element 8 is a compression spring. The top end of the compression spring abuts against the upper die base 4, and the bottom end of the compression spring is sleeved on the top of the ejector rod 7 and abuts against the anti-detachment ring 71. The top left and right sides of the mold base 5 are connected to lower connecting blocks 51. The tops of the two lower connecting blocks 51 are connected to a support plate 9. The top of the support plate 9 is fixedly connected to a lower mold 10. The top surface of the lower mold 10 has a receiving groove 101. A top block 110 is installed in the receiving groove 101. A connecting rod 111 is fixedly connected to the bottom of the top block 110. The connecting rod 111 longitudinally passes through the lower mold 10 and the support plate 9. A telescopic joint is longitudinally installed on the top of the lower mold base 5. Cylinder 120, telescopic cylinder 120 is a pneumatic cylinder. The telescopic end of telescopic cylinder 120 is connected to connecting rod 111. The upper mold 6 is a concave mold and the lower mold 10 is a convex mold. The upper mold 6 and the lower mold 10 cooperate. When the anti-detachment ring 71 abuts against the top surface of the upper mold 6, the ejector rod 7 protrudes from the bottom surface of the upper mold 6. The ejector rod 7 can also move upward until the bottom of the ejector rod 7 is flush with the bottom surface of the upper mold 6. The telescopic cylinder 120 can lift the ejector block 110 upward.

[0014] In actual use, the door shell is placed on the lower mold 10 (this application is an improvement on the stamping die; the limiting device for the door shell is not an innovation of this application, so it will not be described in detail). The upper mold 6 is driven to move downward by the hydraulic cylinder 3. The upper mold 6 and the lower mold 10 can jointly stamp and shape the door shell between them. After stamping, the upper mold 6 is driven to move upward by the hydraulic cylinder 3. During the upward movement of the upper mold 6, the ejector rod 7, under the action of the elastic element 8, always presses the refrigerator door shell onto the lower mold 10, so that the refrigerator door shell can be smoothly removed from the upper mold 6. After the ejector rod 7 leaves the refrigerator door shell, the ejector block 110 is driven to move upward by the telescopic cylinder 120, so that the refrigerator door shell can be smoothly removed from the lower mold 10, eliminating the problem of unsuccessful demolding and ensuring that the demolded refrigerator door shell is located in the correct part removal position.
