[0022] like Figures 1 to 3 As shown, a mold for integral molding of a pouring cup and a mold head includes a base 1. The base 1 has a central hole in the middle and a boss 12 on the inner side wall of the central hole. The large diameter end of the pouring cup 7 can be placed on the boss 12 of the central hole with its large diameter end facing down. Preferably, a buffer pad 13 is provided on the boss 12 to prevent the ceramic pouring cup 7 from making hard contact with the boss 12.

[0023] A lifting cylinder 2 is provided below the central hole. The end of the cylinder rod of the lifting cylinder 2 is connected to a frustum 10. The size and taper of the frustum 10 match the size and taper of the inner side of the pouring cup 7. The lifting cylinder 2 drives the frustum 10 to rise, which can seal the pouring cup 7 on the boss 12.

[0024] The present invention has a moving mold 4 and a fixed mold 3 on one side of the upper part of the base 1. The fixed mold 3 is fixed on the base 1 by the gate fixed mold 6. The moving mold 4 is connected to the gate moving mold 5 below.

[0026] The top circumferential sidewall of the frustum component 10 is provided with a mounting groove, in which an annular sealing ring 11 is installed. The outer dimensions and taper of the annular sealing ring 11 are consistent with the outer dimensions and taper of the frustum component 10. This structure ensures that wax will not overflow through the sprue cup 7 during the production of the mold wax part, thereby guaranteeing product quality.

[0027] The truncated cone part 10 of this utility model has a mold head screw mounting hole at its center. The mold head screw 9 can be placed in the mold head screw mounting hole. The mold head screw 9 is also integrally formed in the mold head wax part. The end of the mold head screw mounting hole is provided with a screw sealing ring to prevent wax from entering the mold head screw mounting hole and affecting the subsequent placement of the mold head screw 9.

[0028] The fixed mold 6 of this utility model can be detachably installed on the fixed mold 3 of the mold head, and the movable mold 5 can be detachably installed on the movable mold 4 of the mold head. Due to the diversity of wax products, this utility model does not require modification of the original mold head wax cavity. It only needs to set a detachable fixed mold 6 and movable mold 5 above the base 1 for positioning and sealing the sprue cup 7. When faced with different mold heads, it is only necessary to replace the mold head on the fixed mold 6 and movable mold 5.

[0029] The upper surface of the base 1 is preferably provided with a positioning and mounting groove.

[0030] Specific production steps of this utility model: In the initial position, the frustum part 10 is located below the boss 12 of the center hole. First, place the sprue cup 7 with its large diameter end facing down on the boss 12, and at the same time, the sprue cup 7 is inserted into the conical hole of the sprue mold 6. Then insert the die head screw 9 into the die head screw mounting hole; The moving mold 5 at the gate and the moving mold 4 at the mold head move to perform the mold closing action; The lifting cylinder 2 drives the truncated cone 10 to rise, sealing the inside of the sprue cup 7. The rising of the truncated cone 10 also causes the sprue cup 7 to fit tightly with the conical hole between the sprue cup 7 and the fixed mold 6 and the moving mold 5. Perform the wax injection process, and then wait for it to cool. After cooling, the gate moving mold 5 and the mold head moving mold 4 move, and the mold can be opened to remove the one-piece molded gate cup 7 and mold head.

[0031] In the process of making mold head wax parts, since the sprue cup 7 in the fixed mold 6 and the moving mold 5 can be integrally molded onto the mold head wax parts, the manual pasting process is eliminated. Moreover, the integrally molded sprue cup 7 and mold head result in stable product quality and a high degree of automation.
