Technical Field

[0001] This utility model relates to the field of molding technology, specifically to a molding device. Background Technology

[0002] Household appliances refer to various electrical and electronic appliances used in homes and similar places. They liberate people from heavy, tedious, and time-consuming housework, creating a more comfortable, beautiful, and healthier living and working environment for humankind, and providing a rich variety of cultural and entertainment conditions. They have become necessities for modern family life. The production process of household appliances generally involves manufacturing various components of the appliance and then assembling them to complete the production. Some of the components are made of metal or stampable materials. During their production, they need to be stamped into shape using stamping dies to create usable components. Therefore, stamping dies for household appliance components are required for this purpose.

[0003] The stamping dies used in the stamping process of existing household appliances still have certain shortcomings in actual use: existing dies usually use ejectors to lift the stamped parts during demolding. However, when dealing with stamped parts with thin inner walls, the pressure of the ejector pins may cause convex damage to the thin wall of the finished product, affecting its output quality. Based on the shortcomings of existing technology, this utility model designs a stamping device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a molding device that has the advantage of preventing damage during demolding.

[0005] This utility model provides the following technical solution: a molding device, including a base, a molding structure fixedly installed on the top of the base, the molding structure including a first mold, the first mold having a stamping groove inside, a bottom groove having a bottom groove, and a demolding structure installed on a fixed rod inside the bottom groove; the demolding structure including a support plate, a moving rail, and a second wedge block, a threaded rod being installed on the internal thread of the support plate, a first wedge block being rotatably installed at the end of the threaded rod, the first wedge block being slidably connected to the moving rail, a fixed frame being fixedly installed on the top of the second wedge block, a plurality of uprights being fixedly installed on the top of the fixed frame, and a demolding template being fixedly installed on the top of the plurality of uprights.

[0006] As a preferred embodiment of this utility model, the stamping groove has an internal cavity that matches the size of the template.

[0007] As a preferred embodiment of this utility model, abutment plates are fixedly installed on both sides of the hollow groove, and the two abutment plates have holes and slots inside.

[0008] As a preferred technical solution of this utility model, the two holes and slots are movably connected to the uprights on both sides.

[0009] As a preferred embodiment of this utility model, side rods are fixedly installed on both sides of the outer surface of the base, and a top plate is fixedly installed on the top of the two side rods.

[0010] As a preferred embodiment of this utility model, a stamping cylinder is fixedly installed on the top of the top plate, and a stamping die is fixedly installed on one end of the telescopic rod of the stamping cylinder.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This molding device, through a demolding structure, allows for demolding by rotating a threaded rod, which rotates and moves forward within a support plate. This, in turn, pushes a first wedge block horizontally forward within a moving rail. Since the inclined surfaces of the first and second wedge blocks are in contact, the movement of the first wedge block pushes the second wedge block, causing the fixed frame to rise. This allows the ejector plate to push the finished product inside the stamping groove upward via a vertical rod. Due to the increased contact area between the ejector plate and the finished product, and the support from the bottom vertical rod, the ejector plate reduces pressure on the finished product and improves demolding stability compared to traditional ejector pin demolding.

[0020] Please see Figure 1-5 A molding device includes a base 1, a molding structure 2 fixedly installed on the top of the base 1, the molding structure 2 including a first mold 21, a stamping groove 22 opened inside the first mold 21, a bottom groove 23 opened at the bottom of the first mold 21, and a demolding structure 10 installed on a fixed rod inside the bottom groove 23; the demolding structure 10 includes a support plate 101, a moving rail 104, and a second wedge block 105, a threaded rod 102 is threaded inside the support plate 101, a first wedge block 103 is rotatably installed at the end of the threaded rod 102, the first wedge block 103 is slidably connected to the moving rail 104, a fixed frame 106 is fixedly installed on the top of the second wedge block 105, a plurality of uprights 107 are fixedly installed on the top of the fixed frame 106, and a demolding template 108 is fixedly installed on the top of the plurality of uprights 107.

[0021] Please see Figure 1-3 The stamping groove 22 has an internal slot 24 that matches the size of the release template 108. Support plates 25 are fixedly installed on both sides of the slot 24, and the two support plates 25 have internal holes 26. The two holes 26 are movably connected to the two side uprights 107. Side rods 3 are fixedly installed on both sides of the outer surface of the base 1, and a top plate 4 is fixedly installed on the top of the two side rods 3. A stamping cylinder 5 is fixedly installed on the top of the top plate 4, and a stamping die 6 is fixedly installed at one end of the telescopic rod of the stamping cylinder 5.

[0022] The ejector plate 108 can be limited by two abutment plates 25. The uprights 107 on both sides are movably connected to the slots 26, which can also limit the ejector plate 108. The stamping cylinder 5 drives its telescopic rod to drive the stamping die 6 to perform the stamping operation. The stamping die 6 can be flexibly replaced by bolts according to the stamped product.

[0023] Please see Figure 1-4 First slide rails 7 are fixedly installed on both sides of the outer surface of the first mold 21, and the two sides of the first slide rails 7 are slidably connected to the base 1. Second mold 8 is fixedly installed on one side of the outer surface of the first mold 21, and second mold 9 is fixedly installed on both sides of the outer surface of the second mold 8.

[0024] The first slide rail 7 and the second mold 9 are slidably connected to the base 1, allowing for flexible replacement between the base 1 and the second mold 8, thereby improving the molding efficiency of the device.

[0025] Working principle: When a stamping device is used, the stamping part is first placed on top of the first mold 21. Then, the stamping cylinder 5 drives the telescopic rod to drive the stamping mold 6 to stamp. After stamping, the threaded rod 102 is rotated to rotate and move forward inside the support plate 101. This pushes the first wedge block 103 to move horizontally forward inside the moving rail 104. Since the inclined surface of the first wedge block 103 is in contact with the inclined surface of the second wedge block 105, the movement of the first wedge block 103 can push the second wedge block 105 to drive the fixed frame 106 to rise. This allows the ejector plate 108 to push the finished product inside the stamping groove 22 upward through the upright rod 107. Since the contact area between the ejector plate 108 and the finished product is increased, and the bottom is supported by the upright rod 107, the ejector plate 108 can reduce the pressure on the finished product and improve the stability of the ejection process compared to traditional ejector pin ejection.
