Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying 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 fig. 1-4, the present invention provides a technical solution: the utility model provides an injection mold for household electrical appliances switch, includes

mount

1, 1 inboard both ends of mount are equipped with movable mould 2 and quiet mould 3 respectively, be equipped with injection moulding mouth 4 on the quiet mould 3, and be equipped with guide post 5 on the quiet mould 3, be equipped with the guiding hole on the movable mould 2, the guiding hole is passed on fixed mount 1 to the one end that quiet mould 3 was kept away from to guide post 5, and through guiding hole and guide post 5, carry out spacingly to movable mould 2, be fixed with pneumatic cylinder 6 on the movable mould 2, pneumatic cylinder 6 is fixed on mount 1, drives movable mould 2 through pneumatic cylinder 6 and removes, be equipped with the shedder 7 that is convenient for carry out the drawing of patterns with injection molding on the quiet mould 3.

The demolding device 7 comprises an upper contact plate 8, fixing grooves 9 are formed in the symmetrical sides of the static mold 3, the upper contact plate 8 and the fixing grooves 9 are identical in radius, and can be just clamped in the fixing grooves 9;

the axial section of the fixed groove 9 is convex, a first spring 10 is fixed on the bottom wall of the fixed groove 9, two moving blocks 11 are fixed on the first spring 10, the two upper contact plates 8 are respectively fixed on the two moving blocks 11, the cross sections of the moving blocks 11 and the upper contact plates 8 are both circular, the radius of the moving blocks 11 is smaller than that of the upper contact plates 8, the contact area between the moving blocks 11 and the fixed groove 9 is reduced, and the upper contact plates 8 can move conveniently;

after the injection molding product is molded, the movable mold 2 is driven to move back through the hydraulic cylinder 6, the first spring 10 loses the pressure applied by the movable mold 2 at the moment, the shape of the first spring is recovered, the upper contact plate 8 in contact with the injection molding product is driven to extend out of the fixed groove 9, and therefore the injection molding product is removed from the static mold 3.
