[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] As described in the background technology, during the manufacturing process of stainless steel VC, although laser welding technology solves the welding problem, the surface of the product is prone to unevenness after laser welding, which directly affects the appearance quality and performance stability of the product.

[0030] In order to solve this technical problem, the utility model provides a VC temperature equalizing plate shaping mold, which is used for leveling the skirt of the stainless steel VC temperature equalizing plate after laser welding.

[0031] Specifically, please refer to Figure 1-Figure 3 VC temperature plate shaping mold specifically includes:

[0032] The upper mold 1 has an upper contoured groove 101 on one side thereof which matches the shape of the VC temperature equalizing plate, and a plurality of raised ribs 102 are fixedly connected to a side of the upper mold 1 close to the upper contoured groove 101 , and the plurality of raised ribs 102 are arranged around the upper contoured groove 101 .

[0033] The VC temperature equalizing plate shaping mold provided by the utility model has raised ribs 102 arranged on the upper mold 1, so that when the upper mold 1 flattens the VC temperature equalizing plate under the action of pressure, a local depression can be produced on the skirt surface of the VC temperature equalizing plate, and the surface shell of the VC temperature equalizing plate is stretched toward the skirt, so as to achieve the effect of flattening the surface of the VC temperature equalizing plate. During this action, the VC temperature equalizing plate is avoided by the upper profiling groove 101 to avoid crushing the effective working area of ​​the product.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0037] Example 1, please refer to Figure 1-Figure 3The VC temperature equalizing plate shaping mold comprises an upper mold 1, one side of the upper mold 1 is provided with an upper profiling groove 101 adapted to the shape of the VC temperature equalizing plate, and a side of the upper mold 1 close to the upper profiling groove 101 is fixedly connected with a plurality of raised ribs 102, and the plurality of raised ribs 102 are arranged around the upper profiling groove 101. By means of the raised ribs 102 arranged on the upper mold 1, when the upper mold 1 flattens the VC temperature equalizing plate under pressure, a local depression can be generated on the skirt surface of the VC temperature equalizing plate, and the surface shell of the VC temperature equalizing plate is stretched toward the skirt to realize the flattening of the surface of the VC temperature equalizing plate. During this action, the VC temperature equalizing plate is avoided through the upper profiling groove 101 to avoid crushing of the effective working area of ​​the product.

[0038] Furthermore, the raised ribs 102 are used to make the surface of the VC temperature averaging board skirt concave, so that the surface shell of the VC temperature averaging board is stretched toward the skirt, so as to achieve the flattening of the surface of the VC temperature averaging board;

[0039] Specifically, the raised ribs 102 will produce local depressions on the surface of the skirt of the stainless steel VC temperature-averaging plate in the shaping mold, but this design is to achieve the effect of surface leveling; first of all, it should be understood that the design purpose of the shaping mold is to correct the unevenness of the surface of the stainless steel VC temperature-averaging plate by applying precise and controlled pressure. When the shaping mold applies pressure, the raised ribs 102 will apply greater force to specific areas of the surface of the skirt of the stainless steel VC temperature-averaging plate, thereby producing local depressions on the surface of the skirt; this local depression is not a side effect of shaping, but a key step in achieving surface leveling. Through the local depressions produced by the raised ribs 102, the shaping mold can stretch the shell of the surface of the stainless steel VC temperature-averaging plate toward the skirt. This stretching effect is actually correcting the unevenness of the surface of the stainless steel VC temperature-averaging plate, making it smoother.

[0040] Further, such as Figure 1-Figure 2 As shown, it also includes a lower mold 2 used in conjunction with the upper mold 1. The lower mold 2 is provided with a lower contoured groove 201 that is adapted to the shape of the VC temperature equalizing plate on one side close to the upper mold 1. The lower contoured groove 201 is used to cooperate with the upper contoured groove 101 to avoid crushing the effective working area of ​​the VC temperature equalizing plate.

[0041] Further, such as Figure 1-Figure 3 As shown, a plurality of positioning pins 4 are fixedly installed on one side of the lower mold 2 close to the upper mold 1, and the plurality of positioning pins 4 are arranged around the lower profiling groove 201, and a plurality of pin grooves 401 are opened on one side of the upper mold 1 close to the lower mold 2, and the plurality of pin grooves 401 are arranged around the upper profiling groove 101, and the positions of the plurality of pin grooves 401 correspond to the positions of the plurality of positioning pins 4 respectively. In the process of placing the VC temperature equalizing plate into the lower profiling groove 201, the VC temperature equalizing plate can be positioned by the positioning pins 4, so as to improve the accuracy of the placement of the VC temperature equalizing plate.

[0042] Further, such as Figure 1-Figure 3 As shown, a plurality of positioning posts 3 are fixedly installed on one side of the lower mold 2 close to the upper mold 1, and a plurality of positioning grooves 301 for inserting the positioning posts 3 are opened on the upper mold 1. The positioning posts 3 and the positioning grooves 301 are used together for positioning during the mold closing process of the upper mold 1 and the lower mold 2, thereby improving the accuracy of the mold closing between the upper mold 1 and the lower mold 2.

[0043] Further, such as Figure 4 As shown, a hydraulic mechanism 5 is provided between the upper mold 1 and the lower mold 2. The hydraulic mechanism 5 is used to drive the upper mold 1 and the lower mold 2 to close and separate the molds. The hydraulic mechanism 5 can provide pressure to the upper mold 1 during closing the molds, so as to achieve the leveling of the surface of the VC temperature equalizing plate by the upper mold 1.

[0044] Example 2, the VC temperature plate shaping mold provided in Example 1 is further optimized, specifically, as follows Figure 4 As shown, the hydraulic mechanism 5 includes a base 501, a plurality of columns 502 are fixedly installed on the top of the base 501, a fixed platform 503 is fixedly connected between the plurality of columns 502, a first hydraulic cylinder 504 is fixedly installed on the top of the fixed platform 503, the telescopic end of the first hydraulic cylinder 504 passes through the fixed platform 503 and is fixedly connected with a lifting plate 505, the upper mold 1 is installed at the bottom of the lifting plate 505, the lifting plate 505 is connected with the outer surface of the column 502, the first hydraulic cylinder 504 can drive the lifting plate 505 to move up and down through the lifting plate 505, and the upper mold 1 can be driven to move up and down through the lifting plate 505, so as to realize mold closing and mold separation;

[0045] Limit rods 506 are fixedly connected to both sides of the top of the lifting plate 505. The top of the limit rods 506 passes through the fixed platform 503 and extends above the fixed platform 503. The limit rods 506 can limit the lifting process of the lifting plate 505 to improve the stability of the lifting process of the lifting plate 505.

[0046] Further, such as Figure 4 As shown, two slide rails 507 are fixedly installed on the top of the base 501, and the surfaces of the two slide rails 507 are slidably connected with a plurality of slide seats 508. The lower mold 2 is installed between the tops of the plurality of slide seats 508. The slide seats 508 and the slide rails 507 cooperate with each other to support the lower mold 2 and enable the lower mold 2 to move horizontally. After the lower mold 2 is removed from under the upper mold 1 and then the VC temperature equalizing plate is driven, the safety of the process of taking and placing the VC temperature equalizing plate can be improved, and the operating space can be increased, which is convenient for operation.

[0047] Further, such as Figure 4As shown, a second hydraulic cylinder 509 is fixedly installed on the top of the base 501 , and the telescopic end of the second hydraulic cylinder 509 is connected to the lower mold 2 , and the lower mold 2 can be driven to move horizontally through the second hydraulic cylinder 509 .

[0048] Example 3, the VC temperature plate shaping mold provided in Example 2 is further optimized, specifically, as follows Figure 5 As shown, an air hole 604 is provided through the bottom of the inner cavity of the lower profiling groove 201, a sleeve 6 is fixedly installed on the top of the base 501, an air cavity 601 is provided in the sleeve 6, a hollow piston 602 is slidably connected in the air cavity 601, a middle hole tube 603 is fixedly connected to one side of the hollow piston 602, and one end of the middle hole tube 603 away from the hollow piston 602 is fixedly connected to the bottom of the upper mold 1 and communicated with the air hole 604. After the VC temperature averaging plate is placed in the lower profiling groove 201, when the lower mold 2 moves to the bottom of the upper mold 1, the middle hole tube 603, the hollow piston 602 and the air cavity 601 can cooperate to generate negative pressure between the air hole 604 and the lower mold 2 to suck the VC temperature averaging plate, thereby fixing the VC temperature averaging plate, and further improving the stability of the VC temperature averaging plate processing process. When the lower mold 2 is moved away from the bottom of the upper mold 1, the air pressure between 604 and the lower mold 2 is restored, thereby releasing the fixation of the VC temperature averaging plate.

[0049] The use process of the VC temperature plate shaping mold provided by the utility model is as follows:

[0050] The second hydraulic cylinder 509 pushes the lower mold 2 to move toward the sleeve 6, so that the lower mold 2 moves away from directly below the upper mold 1, and the VC temperature-averaging plate is placed in the lower contoured groove 201. The second hydraulic cylinder 509 pushes the lower mold 2 to move away from the sleeve 6. At this time, the middle hole tube 603, the hollow piston 602 and the air cavity 601 cooperate to generate negative pressure between the air hole 604 and the lower mold 2 to suck the VC temperature-averaging plate tightly, thereby fixing the VC temperature-averaging plate. The first hydraulic cylinder 504 pushes the upper mold 1 down through the lifting plate 505 so that the upper mold 1, the raised ribs 102 and the lower mold 2 level the VC temperature-averaging plate.
