[0001] The utility model relates to the technical field of forming molds, in particular to a special-shaped valve plate forming mold. Background Art

[0002] The special-shaped valve plate forming mold is a special mold used to manufacture special-shaped valve plates; the special-shaped valve plate is a valve part with a special shape and size, which is used to control the flow of fluid. Due to its complex shape and functional requirements, conventional valve forming molds cannot meet its processing needs, so it is necessary to design and manufacture special-shaped valve plate forming molds.

[0003] Existing special-shaped valve plate forming molds are usually composed of an upper mold and a lower mold, which have a cavity and a channel inside that match the shape of the special-shaped valve plate. In the mold, heat-softened plastic or metal material is injected into the mold cavity by heating and applying pressure. After cooling and solidification, a special-shaped valve plate with a predetermined shape and size is obtained.

[0004] However, in actual use, traditional special-shaped valve plate forming dies lack means for limiting the two sides of the valve plate. Due to the special shape and size of the special-shaped valve plate, without proper positioning during the stamping process of the die, the special-shaped valve plate cannot be accurately placed in the correct position, which in turn causes offset or misalignment during the stamping process, affecting the quality and consistency of the stamping of the special-shaped valve plate.

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0024] First embodiment:

[0025] like Figure 1-4As shown, the special-shaped valve plate forming mold provided by the utility model includes: a forming mold body 100 and a limiting assembly 200, the forming mold body 100 includes an upper mold and a lower mold, the limiting assembly 200 is two groups and are respectively arranged on the side of the lower mold of the forming mold body 100, the limiting assembly 200 includes a connecting shaft 203, the connecting shaft 203 is horizontally arranged and one side is connected to a connecting plate 204, two positioning shafts 205 are slidably arranged on the connecting plate 204, the two positioning shafts 205 are both sleeved with compression springs 206 on the outside, and the other ends of the compression springs 206 are jointly sleeved with a positioning plate 207. In actual use, the user can place the special-shaped valve plate on the lower mold of the forming mold body 100 for bearing, so as to use the upper mold to perform stamping and forming operations on the special-shaped valve plate. During the pressing operation, the guide rod cylinder 202 is connected to the air source and drives the connecting shaft 203 to move, and then the connecting plate 204 can be driven to move linearly and horizontally through the connecting shaft 203. At this time, the connecting plate 204 is connected to the positioning shaft 205, and the positioning shaft 205 is installed with the positioning plate 207, until the positioning end shaft 208 set on the positioning plate 207 can contact the side wall of the special-shaped valve plate, and the positioning plate 207 can slide on the outside of the positioning shaft 205. At the same time, when the positioning plate 207 slides, the two compression springs 206 can be compressed. When the positioning end shaft 208 contacts the special-shaped valve plate on the molding mold body 100, the two compression springs 206 set at this time will be reset, thereby pushing the positioning end shaft 208 again to always be tightly against the side of the special-shaped valve plate.

[0026] By means of the sliding installation between the compression spring 206 and the positioning shaft 205, and the sliding installation between the positioning shaft 205 and the positioning plate 207, the positioning end shaft 208 can be reset by the compression spring 206 and thus always pressed against the side of the special-shaped valve plate, and can then always press against the special-shaped valve plate according to different shapes and sizes, so as to ensure the position accuracy and stability of the special-shaped valve plate during the stamping process.

[0027] Second embodiment:

[0028] like Figure 2-3 As shown, a positioning end shaft 208 is assembled on the side of the positioning plate 207, and a rubber head 213 is sleeved inside the positioning end shaft 208, and two groups of two rubber heads 213 are horizontally arranged opposite to each other; during movement, when the special-shaped valve plate is placed on the lower mold of the molding mold body 100, the positioning end shaft 208 moves horizontally, and the rubber head 213 arranged at the end of the positioning end shaft 208 will first contact the side of the special-shaped valve plate.

[0029] The rubber head 213 provided can provide soft support, so that the special-shaped valve plate can obtain uniform force distribution during the limiting stamping process, which helps to reduce impact and stress concentration, thereby protecting the surface of the valve plate from damage; at the same time, the rubber head 213 provided can play a role in buffering impact force, reducing the impact force on the special-shaped valve plate during the stamping process, and the rubber head 213 provided can absorb part of the impact energy, reducing the risk of deformation and damage of the valve plate.

[0030] Third embodiment:

[0031] like Figure 2-4 As shown, a plurality of holes are opened on the outside of the positioning plate 207 around its center, and positioning bolts 214 are threadedly connected in the plurality of holes. The ends of the positioning bolts 214 pass through the positioning end shaft 208 and abut against the rubber head 213. In actual installation, when the user needs to install the rubber head 213, the rubber head 213 can be placed in the installation hole of the positioning end shaft 208, and then the plurality of positioning bolts 214 are tightened so that the ends of the positioning bolts 214 are tightly abutted against the rubber head 213, thereby achieving the limitation of the rubber head 213.

[0032] The detachable assembly between the positioning bolt 214 and the rubber head 213 makes the rubber head 213 more convenient to assemble and disassemble. When using the positioning bolt 214 to detachably assemble the rubber head 213, the user needs to select a rubber head 213 of appropriate hardness and thickness to ensure that it provides suitable support and cushioning effects to avoid poor cushioning effect of the rubber head 213.

[0033] Fourth embodiment:

[0034] like Figure 2-4 As shown, the limiting assembly 200 also includes a bottom base 201 arranged on the side of the molding mold body 100, the bottom base 201 is L-shaped and formed with a parallel portion and a vertical portion, and a guide rod cylinder 202 is assembled on the vertical portion, and the output end of the guide rod cylinder 202 extends radially and is connected to the connecting shaft 203; during the movement, the user connects the guide rod cylinder 202 to an external air source, and then connects the air source controller, so that the guide rod cylinder 202 drives the connecting shaft 203 to be pushed out to one side, and at this time, through the connection between the connecting shaft 203 and the connecting plate 204, the set connecting plate 204 can drive the positioning shaft 205 and the compression spring 206 to extend synchronously.

[0035] The stroke of the connecting plate 204 can be controlled by the provided connecting shaft 203. Considering the different sizes of the two sides of the special-shaped valve plate, in a preferred embodiment, the clamping interval of the positioning end shaft 208 is radially adjusted by the guide rod cylinder 202. The linear push of the connecting shaft 203 by the provided guide rod cylinder 202 allows the positioning end shaft 208 to be pushed in different strokes in the horizontal direction, thereby tightly limiting the special-shaped valve plates of different lengths. At the same time, by accurately adjusting the moving stroke of the positioning end shaft 208, the size of the limiting force can be controlled to ensure the accurate position of the special-shaped valve plate during the stamping process.

[0036] Fifth embodiment:

[0037] like Figure 2-4 As shown, two bearing seats 209 are provided on the bottom base 201, and the upper end surfaces of the two bearing seats 209 jointly support a bearing plate 210, and a linear slide rail 211 is slidably provided on the bearing plate 210; during movement, the linear slide rail 211 can be detachably assembled on the bearing plate 210, and the bearing seats 209 can be replaced according to actual conditions to provide vertical support of different heights for the linear slide rail 211.

[0038] The linear guide rail 211 can be supported by the support plate 210. In a preferred embodiment, the linear guide rail 211 is detachably mounted on the support plate 210 by bolts, so that the stroke length of the linear guide rail 211 can be replaced and adjusted according to actual usage.

[0039] Sixth embodiment:

[0040] like Figure 2-4 As shown, a linear slider 212 is slidably assembled on the linear guide rail 211, and the connecting plate 204 is overall L-shaped and detachably assembled on the linear slider 212 by bolts. During movement, when the guide rod cylinder 202 is connected to the air source and drives the connecting shaft 203 to move, the linear slider 212 arranged on the linear guide rail 211 can drive the connecting plate 204 to perform smooth linear movement, thereby avoiding the connecting plate 204 from tilting or lateral deviation.

[0041] The linear limiting of the positioning bolt 214 between the linear slider 212 and the linear guide rail 211 and the limiting of the linear slider 212 allow the limiting position to be adjusted according to specific needs, which means that the positioning adjustment can be performed according to the special-shaped valve plate with different edge sizes to ensure the position accuracy and stability of the special-shaped valve plate during the stamping process.

[0042] Working principle: In actual use, when the user needs to perform stamping operation on the special-shaped valve plate, the special-shaped valve plate is placed on the lower die of the forming mold body 100, and then the two sets of limit components 200 are driven to clamp and limit the special-shaped valve plate. Then, the user connects the guide rod cylinder 202 in the two sets of limit components 200 to the external air source, and then connects the air source controller to make the guide rod cylinder 202 drive the connecting shaft 203 to be pushed out to one side. At this time, through the connection between the connecting shaft 203 and the connecting plate 204, the linear limit between the linear slider 212 and the linear guide rail 211 is coordinated to make The connecting plate 204 can drive the positioning shaft 205 and the compression spring 206 to extend synchronously, through the connection between the positioning plate 207 and the compression spring 206, until the positioning end shaft 208 set at the other end of the positioning plate 207 contacts the side of the special-shaped valve plate. Considering the dimensions of both sides of the special-shaped valve plate, the user can drive the positioning end shaft 208 to control the movement of different strokes. When the two positioning end shafts 208 complete the clamping and limiting of the special-shaped valve plate, the user can drive the upper mold of the molding mold body 100 to press down until the stamping of the special-shaped valve plate is completed in cooperation with the lower mold.

[0043] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
