Description

Three-drawer type heel mould

Technical Field

The utility model relates to the technical field of mold, more specifically say, it relates to a three-drawer heel mould.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production; in short, a mold is a tool for making a molded article, which mainly implements the processing of the shape of the article by the change of the physical state of the molded material; the mold directly affects the product manufacturing level.

The existing three-drawer heel mould is manufactured by cutting a mould iron into a mould frame by an electric spark linear cutting machine according to a fixed angle, and then performing secondary cutting on a mould core cut out from the mould frame to form a first mould core, a second mould core and a third mould core; after the molybdenum wire of the electrospark wire-electrode cutting machine cuts the die core, a gap exists between the matching surfaces of the first die core and the second die core and between the first die core and the third die core, and a gap exists between the matching surfaces of the second die core and the third die core (the gap is the diameter of the molybdenum wire); when the first mold core, the second mold core and the third mold core are locked in place by the mold frame, gaps still exist among the first mold core, the second mold core and the third mold core; the product produced by the die has obvious joint line, and the attractiveness and quality of the product are influenced.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The three-drawer heel mold of the present invention will be described in further detail with reference to fig. 1 to 8.

A three-drawing type heel mould comprises a mould frame 1 and a mould core 2 which are cut out from a mould iron, wherein the mould core 2 is cut into a first mould core 21, a second mould core 22 and a third mould core 23 which are matched with each other, and a first cavity for placing the first mould core 21 and a second cavity for placing the second mould core 22 and the third mould core 23 are arranged in the mould frame 1; the inner side wall of the first cavity is obliquely provided with a front matching surface 11, a first left matching surface 13 and a first right matching surface 14, and the inner side wall of the second cavity is obliquely provided with a back matching surface 12, a second left matching surface 15 and a second right matching surface 16; the front side surface, the left side surface and the right side surface of the first die core 21 are correspondingly matched with the front matching surface 11, the first left matching surface 13 and the first right matching surface 14 of the first cavity one by one; the rear side surfaces of the second die core 22 and the third die core 23, the left side surface of the second die core 22 and the right side surface of the third die core 23 are correspondingly matched with the rear matching surface 12, the second left matching surface 15 and the second right matching surface 16 of the second cavity one by one; an included angle between the front matching surface 11 and the rear matching surface 12 is a, an included angle between the first left matching surface 13 and the first right matching surface 14 is b, an included angle between the second left matching surface 15 and the second right matching surface 16 is c, wherein the included angle a is larger than the included angle b, and the included angle c is larger than the included angle b;

when the heel mould is used for forming a heel, a lower pressing mould frame 1 is sleeved on a first mould core 21, a second mould core 22 and a third mould core 23 with cutting gaps, when the mould frame 1 is continuously pressed downwards for final mould locking, because the included angle a between a front matching surface 11 and a rear matching surface 12 is larger than the included angle b between a first left matching surface 13 and a first right matching surface 14, and the included angle c between a second left matching surface 15 and a second right matching surface 16 is larger than the included angle b between the first left matching surface 13 and the first right matching surface 14; when the mold frame 1 is pressed down to the same height, the front matching surface 11 and the back matching surface 12 of the mold frame 1 push the first mold core 21, the second mold core 22 and the third mold core 23 to move closer to each other, and the displacement distance is slightly larger than the displacement distance of the first left matching surface 13 and the first right matching surface 14 pushing the first mold core 21; the displacement distance for pushing the second die core 22 and the third die core 23 to approach each other by the second left matching surface 15 and the second right matching surface 16 is slightly greater than the displacement distance for pushing the first die core 21 by the first left matching surface 13 and the first right matching surface 14; the displacement distance at which the first mold core 21, the second mold core 22 and the third mold core 23 are closed together, and the displacement distance at which the second mold core 22 and the third mold core 23 are closed together; most of cutting gaps generated when the die core 2 is cut by the molybdenum wire for the second time can be eliminated, so that the first die core 21, the second die core 22 and the third die core 23 can be better attached together, a die assembly line does not exist on a product produced by the die, burrs are avoided, the produced product is more attractive, and the product quality is improved; and the user need not to polish the mould of repairing the mould to join in marriage the mould repeatedly to 2 lateral walls on the mould benevolence, reduces the degree of difficulty of mould preparation.
