The slider pouring assembly can increase the connection area between the glue inlet channel and the molding cavity during product injection molding, thereby improving the injection molding efficiency, and can automatically separate from the product when the mold is opened. The translational core pulling assembly can realize automatic core pulling when the mold is opened. The middle inclined top assembly cooperates with the large inclined top ejection assembly to apply thrust to the product during demolding, thereby ejecting the product from the lower template.

[0028] Specifically, the slider casting assembly 6 includes a glue feeding slider 7 corresponding to the large inclined ejection assembly 3 and a slider core pulling structure connected to the glue feeding slider 7. The lower mold 1 is provided with a glue feeding flow channel 8 at one end close to the glue feeding slider 7. The inner end of the glue feeding flow channel 8 is connected to the molding cavity 2, and the connection between the glue feeding slider 7 and the molding cavity 2 is also provided with a connecting flow channel 9 connected to the glue feeding slider 7. When the glue is fed into the molding cavity through the glue feeding flow channel 8, the connection flow channel between the glue feeding slider 7 and the molding cavity 2 can increase the connection area between the molding cavity and the glue feeding flow channel, thereby improving the glue feeding efficiency.

[0029] Specifically, the slider core-pulling structure includes a slider core-pulling seat 10 fixedly connected to the glue-feeding slider 7 and a No. 1 core-pulling rod 11 obliquely fixed on the upper mold plate, and the No. 1 core-pulling rod 11 is obliquely inserted into the slider core-pulling seat 10 and slidably cooperates with the slider core-pulling seat 10. When the mold is opened, the upper mold plate moves upward to drive the No. 1 core-pulling rod to move vertically upward, and the No. 1 core-pulling rod moves vertically upward to drive the slider core-pulling seat and the glue-feeding slider connected to the slider core-pulling seat to move horizontally away from the molding cavity, thereby realizing the separation of the glue-feeding slider and the product.

[0030] Specifically, the translation core-pulling assembly 5 includes a core-pulling insert 12 whose inner end is connected to the large inclined ejection assembly 3 and an insert core-pulling structure connected to the core-pulling insert 12.

When the mold is opened, the upper mold plate moves upward to drive the No. 2 core-pulling rod to move vertically upward. The No. 2 core-pulling rod moves vertically upward to drive the insert core-pulling seat 13 and the core-pulling insert 12 connected to the insert core-pulling seat 13 to move horizontally to the side away from the molding cavity, thereby realizing the core-pulling of the core-pulling insert 12.

[0031] Specifically, the large inclined ejector assembly 3 includes a large inclined ejector 15, which extends from one end of the molding cavity 2 to the other end, and a plurality of inclined ejector rods are fixedly connected to the top of the large inclined ejector 15.
