Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a mold with an easily detachable center support structure. Background Art

[0002] A mold is various molds and tools used in industrial production to obtain required products by methods such as injection molding, blow molding, extrusion, die casting, or forging, smelting, stamping, etc. In short, a mold is a tool for making shaped articles. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the outer shape of articles by changing the physical state of the formed material, and is known as the "mother of industry".

[0003] In the mold industry, the center support usually refers to the guiding and supporting components used in the mold ejection system. For molds with complex ejection structures, such as molds containing small ejector pins, angled ejectors, ejector sleeves (push rods), flat ejector pins, etc., center supports are usually required. According to the characteristics of die-casting production, the product ejector pins are vulnerable parts and need to be frequently replaced. Since the guide bush, ejector pin panel, and ejector pin base plate in the currently used center support of the mold need to be tightly fitted, tools are required to knock them open when removing the ejector pin panel and base plate. This not only has low efficiency but also easily causes accidents.

[0004] Therefore, it is urgent to solve the problem of reforming the structure of the center support for the above technical problems. Content of the Utility Model

[0005] Based on this, it is necessary to provide a mold with an easily detachable center support structure for the above technical problems.

[0022] In this embodiment, as Figures 1 - 3 shown, a mold 20 with an easily detachable center lifter 10 structure is provided, including: an ejection mechanism, a B plate 210 (in a two-plate mold, the B plate refers to the fixed mold part, that is, the fixed side of the mold), and mold feet 110;

[0023] The ejection mechanism includes an ejector plate 220 and a plurality of center lifters 10. The ejector plate 220 is fixedly arranged on the outer wall of the mold base 110.

[0024] Each center lifter 10 includes a guide post 130 and a guide bushing 140. One end of the guide post 130 is fixedly connected to the B plate 210. A guide bushing 140 that mates with the guide post 130 is fixedly arranged on the ejector plate 220. The other end of the guide post 130 passes through the guide bushing 140.

[0025] The guide bushing 140 is slidably sleeved on the guide post 130. The guide bushing 140 includes a first guide bushing 141 and a second guide bushing 142.

[0026] In this embodiment, the center lifter 10 includes a guide post 130 and a guide bushing 140. The guide bushing 140 is fixedly arranged on the ejector plate 220. The guide bushing 140 includes a first guide bushing 141 and a second guide bushing 142. The first guide bushing 141 is fixedly connected to the first ejector plate 230, and the second guide bushing 142 is fixedly connected to the second ejector plate 240. When disassembly and assembly are required, since the first guide bushing 141 and the second guide bushing 142 are movably connected, the first ejector plate 230 and the second ejector plate 240 can be easily separated, which can not only improve work efficiency but also reduce accidents.

[0027] As Figure 1 and Figure 2 shown, in order to make the first ejector plate 230 and the second ejector plate 240 easy to separate, in one embodiment, the first guide bushing 141 and the second guide bushing 142 are movably connected. In this embodiment, a first groove 151 is provided on the first ejector plate 230, a second groove 161 is provided on the second ejector plate 240, a first supporting portion 152 that mates therewith is provided on the first guide bushing 141, and a second supporting portion 162 that mates therewith is provided on the second guide bushing 142. The first guide bushing 141 is nested in the first groove 151 through the first supporting portion 152, the first guide bushing 141 is fixedly connected to the first ejector plate 230, the second guide bushing 142 is nested in the second groove 161 through the second supporting portion 162, the second guide bushing 142 is fixedly connected to the second ejector plate 240, and the outer surface of one end of the first guide bushing 141 abuts against the outer surface of one end of the second guide bushing 142, that is, at least one outer surface of the first ejector plate 230 abuts against the second ejector plate 240, and the first guide bushing 141 and the second guide bushing 142 are movably connected.

[0028] As Figure 1 and Figure 3 shown, in one embodiment, the ejector plate 220 includes a first ejector plate 230 and a second ejector plate 240.

[0029] As Figure 1 shown, in order to keep the first thimble plate 230 stable and not deviate during movement, in one embodiment, the first guide sleeve 141 is fixedly arranged on the first thimble plate 230. In this embodiment, the guide post 130 is fixed, the first guide sleeve 141 is slidably sleeved on the guide post 130, and the inner surface of the first guide sleeve 141 abuts against the outer surface of the column body of the guide post 130. Therefore, when the first guide sleeve 141 slides on the guide post 130, its trajectory will not deviate. And since the first guide sleeve 141 is fixedly connected to the first thimble plate 230, the first thimble plate 230 will keep a stable direction and not deviate during movement.

[0030] As Figure 1 shown, in order to keep the second thimble plate 240 stable and not deviate during movement, in one embodiment, the second guide sleeve 142 is fixedly arranged on the second thimble plate 240. In this embodiment, the guide post 130 is fixed, the second guide sleeve 142 is slidably sleeved on the guide post 130, and the inner surface of the second guide sleeve 142 abuts against the outer surface of the column body of the guide post 130. Therefore, when the second guide sleeve 142 slides on the guide post 130, its trajectory will not deviate. And since the second guide sleeve 142 is fixedly connected to the second thimble plate 240, the second thimble plate 240 will keep a stable direction and not deviate during movement.

[0031] As Figure 1 shown, in one embodiment, the cross-sectional shape of the guide post 130 in the direction perpendicular to its length is circular.

[0032] As Figure 1 shown, in order to reduce the resistance when the guide sleeve 140 slides on the guide post 130, in one embodiment, the guide post 130 is a smooth rod. In this embodiment, setting the guide post 130 as a smooth rod effectively reduces the resistance when the guide sleeve 140 slides on the guide post 130 and prolongs the working life of the component.
