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 used to shape an article. Such tools are made up of various parts, with different molds made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother".

The mold is used in blanking, pressing powder metallurgy parts, pressure casting and the molding process of compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mould has a specific contour or inner cavity shape, the blank can be separated according to the contour shape by applying the contour shape with the cutting edge, and the blank can obtain a corresponding three-dimensional shape by applying the inner cavity shape. The mold generally comprises two parts, namely a movable mold and a fixed mold (or a male mold and a female mold), which can be separated and closed. When the blank is closed, the blank is injected into the inner cavity of the mould for forming.

Preferably, the fixing rod is engaged with the upper end surface of the upper mold when rotated to the horizontal position.

Due to the adoption of the technical scheme, compare with prior art, the utility model discloses following beneficial effect has:

when grouting materials are injected into the cavity groove of the lower die, the upper die is covered on the lower die, and then the rotating disc is manually rotated, so that the stud can move downwards and sequentially passes through the third screw hole, the second screw hole and the first screw hole. Due to the action of the fixing plate, when the stud moves downwards, the fixing rod and the upper die also move in the direction of the lower die. By rotating the rotating disc, the upper die and the lower die can be well clamped, so that the die is molded.

After the mould shaping, through pouring into the cooling water into to condenser tube, can reduce the temperature of mould fast to improve drawing of patterns speed, and then improve work efficiency.

The device has the characteristics of rapid cooling, high demoulding speed and low cost.
