A core 14 is provided inside the lower mold 4. A molding cavity 19 corresponding to the core 14 is opened inside the upper mold 3.

[0030] Insert rods 10 are provided at the corners around the bottom of the upper mold 3, and No. 1 sealing gaskets 11 are provided at the upper ends of the outer peripheries of the insert rods 10. Insert holes 12 are provided at the corners around the top of the lower mold 4, and No. 2 sealing gaskets 16 are provided on the inner sides of the insert holes 12. A reserved groove 13 is provided at the top of the lower mold 4 and located on the outside of the core 14. A No. 3 sealing gasket 20 is provided at the bottom of the upper mold 3 and located on the outside of the molding cavity 19.

[0031] During use, when the upper mold 3 and the lower mold 4 are fitted together, the insertion rod 10 at the bottom of the upper mold 3 can be inserted into the insertion hole 12 at the top of the lower mold 4. When the insertion rod 10 is plugged into the insertion hole 12, the No. 1 sealing gasket 11 on the outer periphery of the insertion hole 12 can fit with the No. 2 sealing gasket 16 on the inner side of the insertion hole 12. Thus, the tightness of the connection between the upper mold 3 and the lower mold 4 can be enhanced by the cooperation of the insertion rod 10, the No. 1 sealing gasket 11, the insertion hole 12 and the No. 2 sealing gasket 16.

[0032] When the upper mold 3 and the lower mold 4 are fitted together, the No. 3 sealing gasket 20 between the upper mold 3 and the lower mold 4 can fill the small gap between the upper mold 3 and the lower mold 4 to further enhance the sealing effect when the upper mold 3 and the lower mold 4 are connected;

[0033] Through the cooperation of the slider 9 and the slide groove 18, when the upper mold 3 moves, the upper mold 3 can slide steadily and smoothly when driven, which is beneficial to improving the accuracy of die-casting.

[0043] When in use, the through hole 17 facilitates the top of the connecting rod 7 to pass through the mounting frame 1 and connect with the output end of the electric push rod 2.

[0044] When the utility model is used, the personnel removes the sealing plug 15 from the injection port 5, and then the raw material of the trailer hook can be injected into the interior of the lower mold 4 through the injection port 5;

[0045] Furthermore, the electric push rod 2 can drive the upper mold 3 to move downward through the connecting rod 7, so that the upper mold 3 can be fitted with the lower mold 4. When the upper mold 3 and the lower mold 4 are fitted together, the insertion rod 10 at the bottom of the upper mold 3 can be inserted into the socket 12 at the top of the lower mold 4. When the insertion rod 10 is plugged into the socket 12, the No. 1 sealing gasket 11 on the outer periphery of the socket 12 can be fitted with the No. 2 sealing gasket 16 on the inner side of the socket 12. Thus, the tightness of the connection between the upper mold 3 and the lower mold 4 can be enhanced by the cooperation of the insertion rod 10, the No. 1 sealing gasket 11, the socket 12 and the No. 2 sealing gasket 16.

[0046] Furthermore, when the upper mold 3 and the lower mold 4 are fitted together, the No. 3 sealing gasket 20 between the upper mold 3 and the lower mold 4 can fill the small gap between the upper mold 3 and the lower mold 4, thereby further enhancing the sealing effect when the upper mold 3 and the lower mold 4 are connected;

[0047] Furthermore, through the cooperation between the slider 9 and the slide groove 18, when the upper mold 3 moves, the upper mold 3 can slide steadily and smoothly when driven, which is beneficial to improving the accuracy of die-casting.
