Abstract

The utility model discloses a forming die capable of molding soft thermoplastic plastic on bottom piece as well as compressing and thinning soft plastic. The forming die comprises a male die, a female die and a driving device, the male die comprises a male die fixing plate, a lower thimble plate, an upper thimble plate, a die support, a male die plate, a male die core and a sprue thimble, the female die comprises a female die core, a female die plate and a female die fixing plate, the male die core is arranged in the male die plate, the male die plate is fixed on the male die fixing plate through the die support, the upper thimble plate is arranged on the lower thimble plate, the lower thimble plate is arranged on the male die fixing plate, the top of the sprue thimble is capable of extending into a sprue cavity of the male die core after penetrating the male die plate and the male die core co as to block the sprue cavity, the bottom end of the sprue thimble is fixed on the upper thimble plate, the female die plate is fixed at the bottom surface of the female fixing plate, the female die core is arranged in the male die plate in fluctuation, when the molding is performed, the driving device is used for driving the female die core to move downward, the die can be used for molding the soft thermoplastic plastic having thickness not more than 0.6mm on the bottom piece, and the trend that the product is developed to light and thin is satisfied.

Description

A kind of on end part the soft thermoplastics type's plastic cement of injection moulding and can simultaneously soft plastic be compressed the mould of attenuation

Technical field

The utility model relates to a kind of mould, relate in particular to a kind of on end part the soft thermoplastics type's plastic cement of injection moulding and can simultaneously soft plastic be compressed the mould of attenuation.

Background technology

Existing metalwork is as the appearance part of product the time, and the metalwork surface easily scratches, and the spot etc. that easily gets rusty must carry out the surface at metalwork and handle,, sprays paint printing etc. as anode.The soft thermoplastics type's plastic cement of injection moulding on metalwork, metal surface anti-scratch and problem of rustiness had both been solved, can make product environmental protection more again, and can energy savings and save multiple advantage such as human cost, but plastic cement thickness must just can flow and solve problems such as joint line more than 0.6mm during because of the soft plastic injection mo(u)lding; So product is whole thick too thick after the moulding, product can't reach the trend to frivolous development.

The utility model content

The utility model purpose: the purpose of this utility model is at the deficiencies in the prior art, provide a kind of on end part the soft thermoplastics type's plastic cement of injection moulding and can simultaneously soft plastic be compressed the mould of attenuation, this mould can be on the end part injection moulding thickness be not more than soft thermoplastics type's plastic cement of 0.6mm, satisfy product to the trend of frivolous development.

Technical scheme: described in the utility model a kind of on end part the soft thermoplastics type's plastic cement of injection moulding and can simultaneously soft plastic be compressed the mould of attenuation, comprise male model and master mold, it is characterized in that, also comprise drive unit, described male model comprises the male model fixed head, following ejector retainner plate, last ejector retainner plate, the mould pin, the male model plate, male model benevolence and cast gate thimble, described master mold comprises mother module core, mother module core is gone into son, caster, die holder, described male model benevolence is arranged in the male model plate, described male model plate is fixed on the male model fixed head by the mould pin, the described ejector retainner plate of going up is arranged on down on the ejector retainner plate, described ejector retainner plate down is arranged on the male model fixed head, the male model plate is passed on described cast gate thimble top and male model benevolence stretches into watering in the oral cavity of male model benevolence, but the oral cavity is watered in shutoff, described cast gate thimble bottom is fixed on the ejector retainner plate, described caster is fixed on the bottom surface of die holder, described mother module core is arranged in the caster, described mother module core is gone into son and can be arranged on up or down in the mother module core, described mother module core is gone into the bottom surface of son and the upper surface of end part is complementary, when carrying out injection moulding, drive unit promotion mother module core is gone into son and is moved downward.

Further, the horn gate chamber is adopted in the described oral cavity of watering.

Above-mentioned on end part the soft thermoplastics type's plastic cement of injection moulding and the operating process that can simultaneously soft plastic be compressed the mould of attenuation be, end part is fixed on the male model benevolence, inject a certain amount of soft thermoplastic plastic of moulding by watering the oral cavity to the upper surface of end part, the oral cavity is watered in the shutoff of mobile cast gate thimble, go into son by drive unit promotion mother module core simultaneously and move downward, soft plastic is compressed attenuation.

The utility model compared with prior art, its beneficial effect is: described in the utility model on end part the soft thermoplastics type's plastic cement of injection moulding and can simultaneously soft plastic be compressed the mould of attenuation, can be on the end part injection moulding thickness be not more than soft thermoplastics type's plastic cement of 0.6mm, satisfy product to the trend of frivolous development.
