Description

Technical Field

[0001] This utility model relates to the field of jewelry processing technology, and in particular to a jewelry forming mold. Background Technology

[0002] In the jewelry manufacturing industry, stamping is a core process for producing precision parts such as rings and pendants. Jewelry forming molds are core equipment in precious metal processing, and their performance directly affects the precision, surface quality, and production efficiency of the jewelry. Especially in the mass production of complex shapes, molds need to combine high-precision forming with rapid demolding capabilities. As a key tool for forming, the demolding efficiency and ease of maintenance of the mold directly affect production efficiency and product quality. Traditional molds mostly adopt an integral structure, relying on manual prying or a single ejection mechanism for demolding, which can easily lead to product deformation and surface scratches.

[0003] Existing jewelry molding molds can cause burrs during demolding. Gold is relatively soft and the edges are easily deformed. Pneumatic demolding, which uses external power to drive the ejector pin assembly to achieve semi-automatic demolding, suffers from problems such as large size and complex maintenance. Therefore, a new jewelry molding mold is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a jewelry molding mold, which aims to improve the situation where tools can cause burrs, gold is relatively soft and the edges are easily deformed, and pneumatic demolding uses external power to drive the ejector pin assembly to achieve semi-automatic demolding, but this has the problems of large size and complex maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jewelry forming mold, comprising a machine body, a connecting block 1 fixedly connected to the lower part of the machine body, a support block fixedly connected to the lower part of the connecting block 1, a hydraulic cylinder disposed inside the machine body, an upper mold fixedly connected to the output end of the hydraulic cylinder, a lower mold slidably connected inside the connecting block 1, a connecting plate 2 slidably connected inside the lower mold, a connecting plate 1 fixedly connected to the lower part of the lower mold, and an ejection assembly disposed inside the connecting plate 1;

[0006] The ejection assembly includes a connecting rod 1, an ejection block, and a sliding rod. The outer wall of the connecting rod 1 is slidably connected to the inside of the lower mold. One side of the outer wall of the ejection block is fixedly connected to one end of the connecting rod 1. One end of the sliding rod is fixedly connected to the other side of the outer wall of the ejection block. A connecting rod 2 is slidably connected to the outer wall of the sliding rod. A tension spring 2 is provided inside the connecting rod 2. A fixing plate is fixedly connected to the outer wall of the tension spring 2. A clamping assembly is provided on the outer wall of the ejection block.

[0007] Furthermore, the clamping assembly includes clamping block one, clamping block two, clamping block three, and clamping block four. The outer wall of clamping block one is slidably connected to the outer wall of the ejector block. The outer wall of clamping block two is slidably connected to the inside of clamping block one. The inside of clamping block three is slidably connected to the outer wall of clamping block two. The outer wall of clamping block four is slidably connected to the inside of clamping blocks one and three. A tension spring one is fixedly connected to one side of the outer wall of clamping block one. One end of the tension spring one is fixedly connected to one side of the outer wall of clamping block three. The outer wall of clamping block two is slidably connected to the inside of clamping block three. A slide rod two is fixedly connected to the inside of clamping block two. A limit block one is slidably connected to the outer wall of slide rod two. The outer wall of slide rod two is slidably connected to the inside of clamping block four. A slide rod one is fixedly connected to the inside of clamping block four.

[0008] Furthermore, the outer wall of the slide rod is slidably connected to the inside of the clamping block, and the inside of the slide rod is fixedly connected to a limit rod.

[0009] Furthermore, a connecting plate three is slidably connected to the outer wall of the limiting rod one, and a support rod is rotatably connected inside the connecting plate three.

[0010] Furthermore, a support plate is fixedly connected to one end of the support rod, and one side of the outer wall of the support plate is fixedly connected to the outer wall of the connecting plate.

[0011] Furthermore, a limiting rod two is slidably connected inside the connecting plate three, and the outer wall of the limiting rod two is fixedly connected inside the sliding rod two.

[0012] Furthermore, a fourth connecting plate is fixedly connected to one side of the outer wall of the first connecting plate, and a second limiting block is slidably connected inside the fourth connecting plate.

[0013] Furthermore, a connecting block two is fixedly connected to one side of the outer wall of the limiting block two, and the outer wall of the connecting block two is slidably connected inside the connecting block one.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the ejector block loses the clamping of the clamping component. At this time, the connecting rod 1 is pushed out by the sliding rod below the ejector block. The sliding rod slides inside the connecting rod 2. The compressed tension spring 2 gives an upward force to push out. The fixing plate is used to fix the connecting rod 2 to prevent displacement. The connecting rod 1 drives the connecting plate 2 to push out upward, achieving the effect of rapid demolding, thereby improving the practicality of the device.

[0016] 2. In this utility model, when it is necessary to replace the connecting plate one, push the connecting block two so that the connecting block two slides inside the connecting block one, causing the limiting block two to leave the groove in the connecting plate four, and then slide the connecting plate one away from the connecting block one, so as to achieve the effect of quickly disassembling the mold, thereby improving the practicality of the device.

[0028] The ejection assembly includes a connecting rod 21, an ejection block 22, and a sliding rod 29. The outer wall of the connecting rod 21 is slidably connected to the inside of the lower mold 6. One side of the outer wall of the ejection block 22 is fixedly connected to one end of the connecting rod 21, and one end of the sliding rod 29 is fixedly connected to the other side of the outer wall of the ejection block 22. The sliding rod 29, in conjunction with the internal tension spring 30, provides a rebound effect, ejecting the ejection block 22, which has lost its clamping assembly, and driving the connecting rod 21. The outer wall of the sliding rod 29 is slidably connected to a connecting rod 27, which contains a tension spring 30. The outer wall of the tension spring 30 is fixedly connected to a fixing plate 28.

The outer wall of clamping block four 24 is slidably connected to the inside of clamping block one 18 and clamping block three 23. A tension spring one 20 is fixedly connected to one side of the outer wall of clamping block one 18. The tension spring one 20 can be used as a clamping block. 18 and 23 provide a certain elastic restoring force to make it more stable during sliding.

[0029] Reference Figures 1-5 The outer wall of slide rod 12 is slidably connected to the inside of clamping block 2 19. Slide rod 12, in conjunction with slide rod 2 16, slides on both sides, which in turn drives clamping block 2 19 and clamping block 4 24 to slide. A limiting rod 13 is fixedly connected inside slide rod 12. The limiting rod 13 is used to fix and connect slide rod 12, preventing unnecessary displacement of slide rod 12. A connecting plate 3 14 is slidably connected to the outer wall of the limiting rod 13. The connecting plate 3 14 drives slide rod 12 and slide rod 2 16 to slide, sliding inwards and outwards simultaneously. A support rod 8 is rotatably connected inside the connecting plate 3 14.

The outer wall of the limit rod 2 15 is fixedly connected to the inside of the sliding rod 2 16. A connecting plate 4 26 is fixedly connected to one side of the outer wall of the connecting plate 1 7. A limit block 2 25 is slidably connected inside the connecting plate 4 26. A connecting block 2 11 is fixedly connected to one side of the outer wall of the limit block 2 25. The connecting block 2 11 slides in conjunction with the limit block 2 25 to achieve the effect of quickly sliding and removing the connecting plate 1 7. The outer wall of the connecting block 2 11 is slidably connected to the inside of the connecting block 1 2.

[0030] Working Principle: When using jewelry forming molds, molten metal is placed in the lower mold 6. The upper mold 5 is pushed by the hydraulic cylinder 4 inside the machine body 1 to squeeze the molten metal. After the molten metal cools, it moves in a circular motion around the support rod 8 via the sliding connecting plate 3 14. The support plate 9 supports the rotation of the support rod 8. The limiting rods 2 15 and 1 13 drive the sliding rods 2 16 and 1 12 to slide within the connecting plate 1 7. The sliding rod 2 16 drives the clamping block 4 24 to slide inside the clamping blocks 1 18 and 3 23. The sliding rod 1 12 drives the clamping block 2 19 to slide inside the clamping blocks 1 18 and 3 23. The clamping block 2 19 is fixed on the sliding rod 2 16, and the clamping block 4 24 is fixed on the sliding rod 1 12. The tension spring 1 20 connects the clamping blocks 1 18 and 3 23. 3. For protection, limit block 17 is used to restrict slide bar 26 from sliding out. Ejector block 22 loses the clamping of the clamping component. At this time, connecting rod 21 will be pushed out by sliding rod 29 below ejector block 22. Sliding rod 29 slides inside connecting rod 27. The compressed tension spring 20 gives an upward force to push it out. Fixing plate 28 is used to fix connecting rod 27 to prevent displacement. Connecting rod 21 drives connecting plate 20 to push upward, achieving the effect of quick demolding. When connecting plate 17 needs to be replaced, connecting block 21 will be pushed, so that connecting block 21 drives limit block 25 to leave the groove in connecting plate 4 26. Then, by sliding connecting plate 17, it leaves connecting block 2, thus achieving the effect of quick mold disassembly. Support block 3 is used to support and fix connecting block 12.
