[0003] The valve core gasket is an important component of the valve core. Its main function is to be used on the water valve to adjust the temperature of various parts of the vehicle body by adjusting the flow direction and flow of the coolant. The sealing ring contains a number of densely packed sealing ribs. The valve core gasket is made by mold pressing, which can conveniently allow the sealing ribs of the valve core gasket to be formed at one time.

[0004] The tool for manufacturing the valve core sealing gasket is a molded structure, including an upper mold plate and a lower mold plate, and a cavity is formed between the upper and lower mold plates. However, in the prior art, the mold with the cavity has a mold seam that is horizontal to the cavity, and the angles between the two ends of the mold seam and the edge of the mold cavity are 90 degrees, and the two sides of the mold seam are beveled edges. Then, the mold seam is cut with a rotating cutter head with a certain bevel angle. When cutting to the edge of the mold seam and the cavity, the tool and the edge of the cavity will have a certain angle, resulting in an inability to be perpendicular. Then, the mold seam and the edge of the cavity cannot be perpendicular, and a second careful cutting with a tool is required, which causes inconvenience and increased difficulty in mold manufacturing.

[0006] Based on the technical problems existing in the background technology, the utility model proposes a valve core sealing gasket mold structure, including two concave molds and convex molds pressed into a valve core sealing gasket cavity, a plurality of sealing rib grooves are arranged in the concave mold, and a first spacing between the sealing rib grooves on the side of the concave mold and the side wall of the concave mold is greater than the second spacing between the sealing rib on the valve core sealing gasket and the edge of the valve core sealing gasket.

[0007] Preferably, the included angle between the end of the sealing rib groove and the inner wall of the female mold is an arbitrary angle.

[0008] Preferably, a spacer is provided between the sealing rib groove and the inner side wall of the concave mold, and the minimum distance between the two spacers is greater than the standard width of the valve core sealing gasket.

[0009] Preferably, the female mold is provided with a guide column, and the male mold is provided with a slot corresponding to the installation of the guide column.

[0010] Preferably, the valve core sealing gasket is cut into a standard size on both sides.

[0011] Compared with the prior art, the valve core sealing gasket mold structure proposed by the utility model adopts the above technical solution and achieves the following technical effects:

[0012] The utility model extends the mold to lengthen the distance between the sealing rib groove on the side and the edge of the concave mold cavity, so that the pressed mold can exceed the conventional size before cutting, avoiding the situation that it is difficult to groove the sealing rib groove on the edge of the mold, and reducing the cost required for mold opening by cutting.

[0020] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0022] Example

[0023] Please refer to Figure 1-Figure 6 The utility model proposes a valve core sealing gasket mold structure, including two concave molds 1 and convex molds 2 pressed into a valve core sealing gasket 7 cavity, a plurality of sealing ribs 71 grooves 11 are arranged in the concave mold 1, and a first interval 3 between the sealing ribs 71 grooves 11 on the side of the concave mold 1 and the side wall of the concave mold 1 is larger than a second interval 4 between the sealing ribs 71 on the valve core sealing gasket 7 and the edge of the valve core sealing gasket 7. In the utility model, the groove width in the concave mold 1 is larger than the width of the valve core sealing gasket 7 produced, and the two sides of the produced valve core sealing gasket 7 can be adjusted by cutting or grinding. A plurality of transverse sealing ribs 71 grooves 11 need to be arranged in the concave mold 1, and the two ends of the sealing ribs 71 grooves 11 need to fit the edges of the sealing ribs 71 grooves 11. When producing the concave mold 1, the tool for producing the concave mold 1 is generally a high-speed rotating tool head. When the tool cuts the sealing ribs 71 grooves 11 on the concave mold 1, in a top view, there will be arc-shaped uncut areas at both ends, and in a front view, there will be arc-shaped uncut areas at both ends. There will be spacers 12, that is, the two ends of the sealing rib 71 groove 11 cannot be cut completely, and need to be continuously cut by a tool to complete. At the same time, the cutting size of the spacer 12 is difficult to adjust. After the spacer 12 is cut, the bottom connecting part of the spacer 12 will have certain burrs, and it is necessary to grind it to complete the production of a concave mold 1. Therefore, in the utility model, by widening the size of the concave mold 1 and lengthening the length of the sealing rib 71 groove 11, the valve core sealing gasket 7 is ground or cut to avoid the grinding process of the spacers 12 on both sides during the production of the concave mold 1.

[0024] In a specific implementation manner, refer to Figure 4 , Figure 5 The angle 5 between the end of the groove 11 of the sealing rib 71 and the inner side wall of the female mold 1 is an arbitrary angle. The angle 5 on the groove 11 of the sealing rib 71 corresponds to the inclination angle of the tool when the slotting tool of different molds rotates, which is usually between 90 degrees and 180 degrees. The smaller the inclination angle, the smaller the bottom width of the spacer 12 will be, and the width of the groove of the female mold 1 that needs to be increased can be reduced.

[0025] In a specific implementation manner, refer to Figure 5 There is a spacer 12 between the sealing rib groove 11 and the inner side wall of the female mold 1, and the minimum spacing 13 between the two spacers 12 is greater than the standard width 14 of the valve core sealing gasket 7. In the present utility model, the minimum spacing 13 between the two spacers 12 needs to be equal to or greater than the width of the product, so that the extra part can be used for cutting the spacer 12 part, providing sufficient cutting space for the spacer 12, while affecting the width of the product.

[0026] In a specific implementation manner, refer to Figure 1 , Figure 2 The female mold 1 is provided with a guide post 21, and the male mold 2 is provided with a slot 15 corresponding to the installation of the guide post 21. The matching of the guide post 21 and the slot 15 can allow the male mold 2 and the female mold 1 to be matched and engaged with each other in a perfect fit.

[0027] In a specific implementation manner, refer to Figure 4 , Figure 5 , Figure 6 , the valve core sealing gasket 7 is formed into a standard size by cutting on both sides. In the utility model, the valve core sealing gasket 7 produced by the female mold 1 and the male mold 2 will be larger than the standard size on both sides, and then cut to make the valve core sealing gasket 7 meet the standard, avoiding the problem of difficulty in manufacturing the female mold 1.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
