[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model discloses a base mold of a discharge valve, comprising a mold body 1, wherein the mold body 1 comprises a fixed mold cover plate 11, and a fixed mold plate 12, a movable mold plate 13 and a movable mold pad 15 are sequentially arranged at the bottom of the fixed mold cover plate 11, and a plurality of groups of slider assemblies 14 are arranged on the top of the movable mold plate 13, wherein the slider assembly 14 comprises two slider brackets 141, and a slider body 142 is movably arranged between the two slider brackets 141, and a core pulling block 143 is arranged at one end of the slider body 142, and an inclined guide column 18 with one end penetrating the interior of the slider body 142 is arranged inside the fixed mold plate 12, and a molding base 2 is arranged between the fixed mold plate 12 and the movable mold plate 13, and one end of the core pulling block 143 away from the slider body 142 extends to the interior of the molding base 2, and a slide groove for installing the slider bracket 141 is opened on the top of the movable mold plate 13, and the slide groove is opposite to and communicated with the avoidance groove 19, so that the inclined guide column 18 can be smoothly inserted into the interior of the avoidance groove 19.

[0024] Specifically, one end of the inclined guide column 18 is sleeved with the internal thread of the fixed mold plate 12. This design makes it easy to replace the inclined guide column 18. When in use, the molten material is injected between the fixed mold plate 12 and the movable mold plate 13 through the gate 121. After cooling and molding, the molding base 2 is obtained. The fixed mold plate 12 and the movable mold plate 13 are separated. Driven by the separation process, the movable mold plate 13 drives the slider assembly 14 to descend, and the slider body 142 is pulled by the inclined guide column 18 to drive the core pulling block 143 to separate from the interior of the molding base 2, thereby completing the core pulling.

[0025] Specifically, the molding base 2 is circular, and several groups of the slider assemblies 14 are distributed in a circular shape with equal spacing on the outside of the molding base 2. The movable template 13 and the movable mold pad 15 are provided with avoidance grooves 19 that are the same in number and opposite to the slider assemblies 14. The bottom end of the inclined guide column 18 passes through the slider body 142 and extends to the inside of the avoidance groove 19. The slider assemblies 14 are distributed in a circular shape with equal spacing, and the consistency is high, so that the core pulling action of all the slider assemblies 14 can be completed when the movable template 13 is separated from the fixed template 12, and the operation method is simpler. Each group of slider assemblies 14 has an independent avoidance groove 19 and a slide groove opposite to each other. This design method allows each group of slider assemblies 14 to be independently used as a water inlet and a water outlet, ensuring the temperature difference balance of the entire cooling system, thereby ensuring the consistent shrinkage of the molding base 2 product molding process, high dimensional accuracy, meeting the user's technical indicators, and no need for subsequent mechanical processing, reducing the processing difficulty and ensuring processing efficiency.

[0026] Specifically, a gate 121 is provided at the middle position of the fixed mold plate 12 .

[0027] Specifically, one end of the core pulling block 143 is clamped with one end of the slider body 142 through a T-block 144, two mold feet 151 are provided at the bottom of the movable mold pad 15, an ejector plate 16 is provided between the two mold feet 151, and a top plate pad 17 is provided at the bottom of the ejector plate 16.

[0028] Specifically, the material of the slider assembly 14 is H13 steel, which is wear-resistant and heat-resistant, reduces the friction between the slider body 142 and the slider bracket 141 and the top slide groove of the movable mold plate 13, and extends the service life of the mold.

[0029] To sum up, the base mold of the discharge valve has several groups of slider assemblies 14 distributed in a ring shape with equal spacing, with high consistency, so that when the movable mold plate 13 is separated from the fixed mold plate 12, the core pulling action of all slider assemblies 14 can be completed, and the operation method is simpler. Each group of slider assemblies 14 has an independent avoidance groove 19 and a slide groove relative to each other. This design method allows each group of slider assemblies 14 to be independently used as a water inlet and outlet, ensuring the temperature difference balance of the entire cooling system, thereby ensuring the consistent shrinkage of the molded base 2 product during the molding process, with high dimensional accuracy, meeting the user's technical indicators, and not requiring subsequent mechanical processing, thereby reducing the processing difficulty and ensuring processing efficiency.
