Abstract

The utility model discloses an air blowing de-molding jig. An accommodation groove is inwards formed in one lateral surface of a first jig block, and a second jig block is fixed on the lateral surface. A through groove communicated with the accommodation groove is formed in the side, opposite to the first jig block, of the second jig block. The working part of a mold core is inserted into the accommodation groove from the through groove. A circle of outwards-raised scraper is arranged on the inner wall of the through groove, and the point of the scraper faces the accommodation groove. An air inlet connected with the through groove is formed in the position, corresponding to the scraper, of one lateral surface of the second jig block. An air outlet communicated with the accommodation groove is formed in one lateral surface of the first jig block. A circle of air inlet groove is formed in the mold core. The jig is used after the opening of a mold, the mold core with a product is inserted into the accommodation groove, and is backwards pulled, the product is separated from the mold core through the point of the scraper, and is expanded by air blown from the air inlet groove to be completely separated from the mold core, and after the mold core is extracted, the jig can be opened to take out the product without damage to the product.

Description

A kind of air blowing mould release tool

Technical field

The utility model relates to silicon rubber mould technical field, particularly a kind of air blowing mould release tool.

Background technology

Shown in Fig. 1 is a kind of silastic product, and the A portion in its feature is bending folded structure, completes after sulfidization molding die sinking, adopts the mode of forced stripper mechanism that goods are taken off.Because this rubber has certain adhesiveness, and its folded structure is comparatively complicated, if forced stripper mechanism very easily damages goods, causes bad.

Utility model content

For solving the problems of the technologies described above, the utility model provides a kind of air blowing mould release tool, and auxiliary goods depart from from core, to realize the object that prevents demoulding damage goods.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of air blowing mould release tool, comprise tool piece one, tool piece two and core, a storage tank is inwardly offered in a side of described tool piece one, described tool piece two is fixed on this side, one side of the relatively described tool piece one of described tool piece two offers the groove being communicated with described storage tank, and the operate portions of described core injects described storage tank from described groove; The scraper that is provided with a circle outwardly convex on the inwall of described groove, the point of a knife of described scraper is towards described storage tank; The corresponding described scraper place, a side of described tool piece two is provided with the air admission hole being connected with described groove, on a side of described tool piece one, offers the venthole communicating with described storage tank; On described core, be provided with a circle air inlet duct.

Preferably, the side that the inwall of described groove is contrary with described scraper point of a knife is provided with the seal groove that sealing ring is installed.

Preferably, on described core, be provided with in a side of the relatively described operate portions of described air inlet duct the seal groove that a circle coordinates with described sealing ring.

Preferably, a side of described tool piece one fixing described tool piece two is provided with projection, and the corresponding described high spot of described tool piece two is provided with the groove mating with described projection.

Preferably, described tool piece one and tool piece two are spliced by two boards material.

Pass through technique scheme, the air blowing mould release tool that the utility model provides, after mould die sinking, use, inject in storage tank with the core of goods, white space in storage tank is the expansion area of goods, in from air admission hole to groove, blow, and core is toward post-tensioning, at this moment the point of a knife of scraper is chosen release core from the oral area of goods by goods, the gas now blowing into from air inlet duct will enter between goods and core, goods is expanded and depart from core completely, after core is extracted out, open tool and just goods can be taken out, can not damage goods.
