The back-off device of a kind of anti-demoulding deformation as above, it is characterised in that be provided with connecting salient points in described back-off boss front end, on rear side of product back-off with connecting salient points relative to position on be provided with link slot, described connecting salient points is arranged in link slot.

The back-off device of a kind of anti-demoulding deformation as above, it is characterized in that described rear mold includes rear pattern plate and rear baffle plate, being respectively provided on two sides with square iron in the rear between template and rear baffle plate, described thimble panel and supporting plate are arranged between rear pattern plate and rear baffle plate.

The back-off device of a kind of anti-demoulding deformation as above, it is characterised in that described front mould is included front template and front mould panel, described front template and front mould panel and is mutually permanently connected by screw.

The back-off device of a kind of anti-demoulding deformation as above, it is characterised in that be provided with guiding mechanism between described front mould and rear mold.

The back-off device of a kind of anti-demoulding deformation as above, it is characterised in that described guiding mechanism includes the guide pin bushing being arranged in front mould template, is provided with guide pillar in the rear in template, described guide pillar is arranged in guide pin bushing.

The back-off device of a kind of anti-demoulding deformation as above, it is characterized in that being provided with several positioning ring grooves on described guide pillar outer wall, graphite circle it is provided with in described positioning ring groove, being provided with ventilative groove in axial direction at described guide pillar, described ventilative groove is connected with the guide pillar of the upper and lower both sides of positioning ring groove.

In sum, relative to prior art, it provides the benefit that this utility model:

In this utility model back-off adopt two lifter ejections, be effectively ensured deform when product tips upside down on the demoulding little, it is prevented that back-off is broken, simple in construction.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.
