At present, the overall structure of the valve core seat is generally first injection molded through an injection mold, and then the inclined holes are manually punched through a punching device. This method of first injection molding and then punching inclined holes can meet certain production requirements, but it also has major defects. The step-by-step operation is inefficient, labor-intensive, and labor-intensive. The cost is high, the product is easily damaged, the yield rate is low, and it cannot effectively meet production requirements.

[0003] The technical problem to be solved by the utility model is to provide a valve core seat oblique withdrawal injection mold which can complete injection molding in one step without drilling, has high operation efficiency, low labor intensity, low labor cost, is not easy to damage the product, has a high yield rate, and effectively meets production requirements. Utility Model Content

[0004] In order to solve the problems of low efficiency, high labor intensity, high labor cost, easy damage to products, low yield rate, and inability to effectively meet production requirements in the above-mentioned prior art, the utility model adopts the following technical solutions:

[0005] The utility model provides a valve core seat oblique extraction injection mold, comprising an upper mold plate, an upper mold foot, an upper mold, a lower mold, a push plate, three oblique extraction cores, a top plate, an ejection spring and a lower mold plate, wherein the upper mold foot is arranged at the bottom of the upper mold plate, the upper mold is fixedly arranged at the bottom of the upper mold foot and is internally provided with a forming upper mold core, the lower mold is arranged directly below the upper mold and is internally provided with a forming lower mold core, the forming lower mold core is located directly below the forming upper mold core, the push plate is arranged at the bottom of the lower mold, the bottoms of the three oblique extraction cores are all fixed on the push plate and the tops are inclined forward and extend through the forming lower mold core to the lower end of the forming upper mold core, the two ends of the bottom of the push plate are fastened to the lower mold plate by bolts, the top plate is fixedly arranged on the lower mold plate, the bottom of the ejection spring is fixed to the top plate, and the top is hung on the push plate.

[0006] Preferably, a gate sleeve is provided in the middle of the upper template.

[0007] The beneficial effects of the utility model are: during processing, injection molding is completed in one step without the need for drilling, the operation efficiency is high, the labor intensity is low, the labor cost is low, it is not easy to damage the product, the yield rate is high, and the production requirements are effectively met. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 The utility model is a schematic structural diagram of an embodiment. Implementation

[0009] The preferred embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0010] See also Figure 1 A valve core seat oblique extraction injection mold, comprising an upper mold plate 1, an upper mold foot 2, an upper mold 3, a lower mold 4, a push plate 5, three oblique core pullers 6, a top plate 7, a material ejection spring 8 and a lower mold plate 9, wherein the upper mold foot 2 is arranged at the bottom of the upper mold plate 1, the upper mold 3 is fixedly arranged at the bottom of the upper mold foot 2 and is provided with a molding upper mold core 31 inside, the lower mold 4 is arranged directly below the upper mold 3 and is provided with a molding lower mold core 41 inside, the molding lower mold core 41 is located directly below the molding upper mold core 31, the push plate 5 is arranged at the bottom of the lower mold 4, the bottoms of the three oblique core pullers 6 are all fixed on the push plate 5 and the tops are tilted forward and extend through the molding lower mold core 4 1 to the lower end of the upper mold core 31, three oblique cores are evenly distributed in a circle, the two ends of the bottom of the push plate 5 are fastened to the lower mold plate 9 by bolts, the top plate 7 is fixed on the lower mold plate 9, the bottom of the ejection spring 8 is fixed on the top plate 7, and the top is hung on the push plate 5. When the mold is closed, the oblique core is pushed to the upper and lower mold cores, and an oblique hole is automatically formed during glue injection. Before opening the mold, the lower mold plate is pulled backward first, and the oblique core can be driven by the ejection spring and the push plate as a whole to move backward away from the upper and lower mold cores. After the oblique core is separated, the upper mold and the lower mold are completely separated and the product is taken out, and the injection molding is completed directly at one time without the need for subsequent drilling.

[0011] A sprue bushing 11 is provided in the middle of the upper mold plate 1, and the rubber material is injected into the upper and lower mold cores from the sprue bushing.

[0012] The beneficial effects of the utility model are: during processing, injection molding is completed in one step without the need for drilling, the operation efficiency is high, the labor intensity is low, the labor cost is low, it is not easy to damage the product, the yield rate is high, and the production requirements are effectively met.

[0013] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
