[0002] There are multiple button holes on the game console handle panel products, among which there are specified holes. After assembling functional parts such as operating levers, it is necessary to retain the pattern or design of the diaphragm. For this reason, the side of these specified holes requires the coating depth of the diaphragm to meet the requirements of the drawings.

[0003] Conventional hot pressing molds usually need to apply a layer of PU glue (generally designed to be 3.0mm thick) on the steel material on one side of the diaphragm surface to protect the diaphragm surface and prevent hard objects from squeezing the surface and causing adverse deformation. This can achieve good results when used in places without grooves. However, for the sides of several countersunk holes with special requirements, since it requires the sides of the countersunk holes to maintain a certain coating depth, and because the PU glue has elasticity, it will rebound on the diaphragm when covering the bottom of the groove, and the stretched depth value of the side of the countersunk hole cannot be solidified. It is easy to cause the side coating depth of the countersunk holes of the manufactured diaphragm products to be inconsistent, which does not meet the production requirements of customers.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 6 In an embodiment of the utility model, a hot pressing mold for improving the forming accuracy of diaphragm countersinks includes an upper mold group 10, a lower mold group 20, a molding mold group 30, a positioning mold group 40 and an insert mold group 50. The upper mold group 10 and the lower mold group 20 cooperate with each other through the positioning of the positioning mold group 40 to form a hot pressing operation on the diaphragm 70. The molding mold group 30 is installed between the upper mold group 10 and the lower mold group 20, and molds the diaphragm 70 into a preset shape. The insert mold group 50 is installed in the molding mold group 30, and cooperates with the molding mold group 30 to mold the diaphragm 70; the insert mold group 50 is provided with a hole insert 51 and a feature insert 52. The hole insert 51 is used to mold the countersink of the diaphragm 70, and the feature insert 52 is sleeved on the hole insert 51, so that the side of the countersink formed by the hole insert 51 forms a preset feature. When the feature insert 52 is sleeved on the hole insert 51 , an inclined side wall 53 with a certain depth is formed between the feature insert 52 and the hole insert 51 , so that the counterbore of the diaphragm 70 forms a side surface with a uniform covering depth.

[0031] Specifically, for the hot pressing operation of some special diaphragms 70, due to the special requirements for the countersunk holes, the molding module 30 needs to be specially designed. In particular, when the side of the countersunk hole needs to be coated to a certain depth, the traditional groove design is prone to inconsistent coating depth due to the elasticity of the PU glue, resulting in defective products. The countersunk hole insert is wrapped by the characteristic insert 52, and the shape design of the characteristic insert 52 is used to form an inclined side wall 53 with a certain depth on the outside of the countersunk hole insert, thereby forming a side coating of a certain depth on the side of the countersunk hole of the diaphragm 70, thereby meeting the production needs. The depth of the side coating can also be kept consistent, reducing the occurrence of defective products and improving production efficiency.

[0032] Secondly, the positioning module 40 is provided with a guide column 41 and a guide sleeve 42, the guide column 41 is fixedly connected to the upper clamping plate 13, the guide sleeve 42 is fixedly connected to the lower template 21, and the guide column 41 and the guide sleeve 42 cooperate with each other, so that the upper clamping plate 13 and the lower clamping plate 23 form a positioning connection. The guide column 41 and the guide sleeve 42 can be existing structures in the prior art, which facilitates the operation of the hot pressing mold and will not be repeated here. In addition, a pin 43 can also be provided to facilitate the docking of the upper and lower templates 21.

[0034] Specifically, the first countersunk hole 71 of the diaphragm 70 has special shape requirements on its side, so it needs to be processed in conjunction with the characteristic insert 52. The first insert hole 33 can guide and limit the characteristic insert 52, so that it can accurately perform hot pressing on the first countersunk hole 71 and form a characteristic shape of corresponding depth covering the side of the first countersunk hole 71.

[0035] like Figure 4 and Figure 5 As shown, preferably, the lower molding core 32 is further provided with a second insert hole 34 , and the insert module 50 is further provided with a second insert 54 , which is installed in the second insert hole 34 and performs molding processing on the second countersunk hole 72 on the diaphragm 70 .

[0036] Specifically, the second countersunk hole 72 is a conventional countersunk hole requirement, so it is not necessary to set a feature insert 52 on the outside of the second insert 54 , and only a conventional countersunk hole insert is required. The corresponding second insert hole 34 also guides and limits the second insert 54 .

[0037] like Figure 6 As shown, preferably, the insert module 50 is also provided with a cup head screw 55 and a depth adjustment gasket 56, and the hole insert 51 and the depth adjustment gasket 56 are respectively and adjustably fixedly connected to the cup head screw 55, and one end of the hole insert 51 abuts against the depth adjustment gasket 56, and the other end thereof extends into the molding module 30.

[0038] Specifically, in order to adapt to diaphragms 70 or countersunk holes of various specifications, a depth adjustment gasket 56 can also be set. By adjusting the depth adjustment gasket 56 using the cup head screw 55, the length of the hole insert 51 relative to the molding module 30 can be adjusted, thereby adjusting the depth of the countersunk hole.

[0039] like Figure 1 and Figure 2 As shown, preferably, the upper die set 10 is provided with an upper die plate 11, and the upper die plate 11 is provided with an upper die hole 12, and the upper die hole 12 is used to pass through and stabilize the upper molding core 31; the lower die set 20 is provided with a lower die plate 21, and the lower die plate 21 is provided with a lower die hole 22, and the lower die hole 22 is used to pass through and stabilize the lower molding core 32. The upper die set 10 is also provided with an upper clamping plate 13, and the upper clamping plate 13 is used to install the upper molding core 31 and the upper die plate 11; the lower die set 20 is also provided with a lower clamping plate 23, and the lower clamping plate 23 is used to install the lower molding core 32 and the lower die plate 21. The upper clamping plate 13 is also provided with a push plate spring 14 and a limit bolt 15, one end of the push plate spring 14 is fixedly connected to the upper clamping plate 13, and the other end thereof abuts against the upper mold plate 11; the limit bolt 15 is fixedly connected to the upper clamping plate 13.

[0040] Specifically, in order to make the hot pressing mold form a complete mold, the upper and lower templates 21 and the corresponding upper and lower clamping plates 23 in the existing structure can also be set. It can be understood that the push plate spring 14 and the limit bolt 15 can also be set to better enable the hot pressing mold to operate. In addition, a heat insulation plate 61 can be set on the upper clamping plate 13, and a foot pad 62 can be set on the lower clamping plate 23. They are all existing structures and will not be repeated here.
