Preferably, the injection mold further comprises an upper mold plate and a lower mold plate, a first mounting groove is formed in the bottom of the upper mold plate, the upper mold core is embedded in the first mounting groove, a second mounting groove is formed in the top of the lower mold plate, and the lower mold core is embedded in the second mounting groove.
Preferably, the injection mold further comprises a fixed bottom plate, and the fixed bottom plate is connected below the lower die plate.
Preferably, the injection mold further comprises an ejection mechanism, the ejection mechanism comprises an ejection plate and an ejector pin, the ejection plate is arranged between the lower die plate and the fixed bottom plate in a lifting mode, the bottom end of the ejector pin is connected with the ejection plate, and the top end of the ejector pin extends into the cavity.
The utility model has the advantages and beneficial effects that: the utility model provides an injection mold glue feeding structure which is reasonable in structure, and the glue feeding insert is adopted to replace a ox horn glue feeding structure formed by splicing two ox horn inserts, so that no insert line is arranged on the surface of a product after injection molding, and the appearance quality of the product is ensured.
Drawings
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is an enlarged view at a in fig. 1.
Description of the embodiments
The following describes the embodiments of the present utility model further with reference to the drawings and examples. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.
The technical scheme of the utility model is as follows:
as shown in fig. 1 and 2, an injection mold glue feeding structure comprises an injection upper mold, an injection lower mold and a pouring system; the injection upper die comprises an upper die core 1, the injection lower die comprises a lower die core 2 matched with the upper die core 1, a cavity is formed by closing the upper die core 1 and the lower die core 2, and an insert mounting cavity is arranged at the outer side of the bottom of the cavity in the lower die core 2;
the glue feeding structure comprises a glue feeding insert 3, the glue feeding insert 3 is arranged in an insert mounting cavity, the top surface of the glue feeding insert 3 is of a concave arc surface structure, a glue guiding groove 31 is formed in the top surface of the glue feeding insert 3, the glue guiding groove 31 extends along the arc direction of the top surface of the glue feeding insert 3, one end of the glue guiding groove 31 is communicated with the cavity, and the other end of the glue guiding groove 31 is communicated with a pouring system.
Further, the injection mold further comprises an upper mold plate 4 and a lower mold plate 5, a first mounting groove is formed in the bottom of the upper mold plate 4, the upper mold core 1 is embedded in the first mounting groove, a second mounting groove is formed in the top of the lower mold plate 5, and the lower mold core 2 is embedded in the second mounting groove.
Further, the injection mold further comprises a fixed bottom plate 6, and the fixed bottom plate 6 is connected below the lower die plate 5.
Further, injection mold still includes ejection mechanism, ejection mechanism includes ejector plate 7 and thimble, ejector plate 7 liftable setting is between lower bolster 5 and fixed bottom plate 6, the bottom and the ejector plate 7 of thimble are connected, and the top of this thimble extends to in the die cavity.
The working principle of the injection mold of the utility model is as follows: when the injection molding die is used, the injection upper die and the injection lower die are matched, the upper die core 1 and the lower die core 2 are closed, and molten plastic is injected into the cavity through the glue guide groove 31 of the glue inlet insert 3 by the pouring system to form a product. When the upper and lower injection molds are opened, the upper mold core 1 and the lower mold core 2 are separated, and the ejector plate 7 drives the ejector pin to move and ejects the product in the cavity. In addition, by adopting the glue feeding insert 3, no insert line is arranged on the surface of the product after injection molding, so that the appearance quality of the product is ensured.
