the upper end face of the glue position insert 2 is provided with a forming part 203 for forming a product, and the glue inlet 202 is communicated with the forming part 203 so as to inject an injection molding raw material into the forming part 203.

Referring to fig. 1-3, the present embodiment provides an injection mold gate structure disposed in a male mold of an injection mold. The injection mold comprises a male mold and a female mold. The male die is provided with a die core fixing frame. The core of the male die is formed by fixing an insert with a forming end surface on a die core fixing frame, and the glue position insert 2 is the insert arranged at the glue position of the product.

The glue feeding structure of the injection mold comprises a glue feeding insert 1 and a glue position insert 2.

The glue inlet insert 1 is fixed in the male die. The glue inlet 1 is internally provided with a first sprue 101 and a runner 102. The branch channels 102 of the glue inlet 1 are communicated with the main channel in the mold, so that the injection molding raw material in the main channel can flow into the branch channels 102. The input end of the first gate 101 is arranged near the upper end of the glue inlet 1, and the input end of the first gate 101 is communicated with the sub-runner 102, so that the injection molding raw material in the sub-runner 102 can flow into the first gate 101. The output end of the first gate 101 penetrates through the side wall of the glue inlet 1, and the first gate 101 is arc-shaped.

The upper end surface of the glue position insert 2 is provided with a forming part 203 for forming a product, and the glue position insert 2 is arranged in the male die through the die core fixing frame to form a die core part of the male die. The glue position insert 2 is arranged on one side of the glue inlet 1 and connected with the glue inlet 1, so that the glue inlet 1 can input injection molding raw materials into the glue position insert 2.

A second gate 201 is provided inside the glue site insert 2, and the second gate 201 has a curved cone shape. The input end of second runner 201 runs through the lateral wall of gluey position income son 2 to when gluey position income son 2 with advance gluey income son 1 and be connected, glue the second runner 201 that position income son 2 is interior can with advance gluey first runner 101 intercommunication that goes into son 1, thereby make the raw materials of moulding plastics in first runner 101 can flow into in the second runner 201. The output end of the second gate 201 extends toward the upper end surface of the glue level insert 2 and penetrates through the upper end surface of the glue level insert 2, so that a glue inlet 202 is formed on the upper end surface of the glue level insert 2. The glue inlet 202 is arranged on the forming part 203 of the glue level insert 2 and is communicated with the forming part 203, so that the injection molding raw material in the second gate 201 can flow into the forming part 203 of the glue level insert 2 through the glue inlet 202, and the injection molding raw material is cured and formed into a product in the forming part 203.

The diameter of the opening at the output end of the first gate 101 is the same as the diameter of the opening at the input end of the second gate 201, so that the first gate 101 and the second gate 201 can be completely aligned and engaged, the installation between the first gate 101 and the second gate 201 is facilitated, and the injection molding material is prevented from overflowing from the connection of the first gate 101 and the second gate 201. The diameter of the first gate 101 gradually decreases from the input end to the output end thereof, that is, the caliber of the input end of the first gate 101 is larger, so that the injection molding raw material can be rapidly injected into the first gate 101, and the flow rate of the injection molding raw material in the mold is ensured. The diameter of the output end of the first gate 101 is smaller to match the diameter of the input end of the second gate 201. This structure allows the first gate 101 and the second gate 201 to constitute a horn gate.

Referring to fig. 4, for a conventional glue-in structure. The horn gate is integrally arranged in the glue inlet insert 1, and the horn gate is formed by splicing two halves of insert which are mirror images due to the special structure of the horn gate. During processing, each half insert is subjected to discharge processing by adopting an electrode so as to form a half horn gate on each half insert, and after the processing is finished, the two half inserts are combined, so that a complete horn gate is formed between the two half inserts. This kind of processing mode, because of the part of every half ox horn structure discharges, can be different because of board equipment and manual operation, and the perfect concatenation of two halves income son and zero clearance after hardly reaching discharging in its precision, the existence of advancing jiao kou 202 department clearance can make the entering point department of product can produce deckle edge, needs artifical postprocessing, extravagant cost of labor, influences productivity and yield.

Referring to fig. 4, for the conventional glue inlet structure, since the gate is disposed in the glue inlet 1, at least a portion of the end surface of the glue inlet 1 contacts with the product, so that the glue inlet 202 of the glue inlet 1 can inject the injection molding material into the cavity of the mold. This arrangement method can cause the glue inlet insert 1 to leave a large trace of the inlet line on the surface of the product, thereby causing the aesthetic degree of the product to be reduced.
