Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to the attached drawing 1 of the specification, an embodiment of the present invention provides a die casting mold, which includes a material cylinder body 1, a fixed mold plate 2 and a movable mold plate 3 that are matched with each other, wherein the fixed mold plate 2 and the movable mold plate 3 are provided with a front mold core 21 and a rear mold core 31 that are matched with each other to form a product cavity. An inlet gate 1a is arranged on the upper side of the feeding end of the charging barrel body 1, an annular bulge 1b is convexly arranged on the peripheral edge of the discharging end of the charging barrel body, and the annular bulge 1 is abutted against the outer side surface of the fixed die plate 2. The end of the discharging end of the charging barrel body 1 extends outwards along the axial direction of the charging barrel body 1 to form an extension part 1 c.
The rear mold core 31 is provided with a shunting part 31a in a protruding mode, the fixed mold plate 2 and the front mold core 21 are provided with openings for the extension parts 1c to pass through, and the extension parts 1c pass through the openings of the fixed mold plate 2 and the front mold core 21 and are sleeved on the shunting part 31a of the rear mold core 31. The upper side wall of the flow splitting portion 31a and the upper side inner wall of the elongated portion 1c are spaced apart from each other by a predetermined distance to form the inlet gate 1 a.
Before die casting, pouring material liquid into a pressure chamber of the charging barrel body 1 from a pouring gate 1 a; in the die casting process, the injection punch 4 is driven to punch the material liquid to the die side, so that the material liquid is converged in the elongated part 1 c; then the injection punch 4 is driven to further act, and the material liquid is pressed into a product cavity formed by the front die core 21 and the rear die core 31.
