Abstract
The utility model provides a die structure of an inclined top with a centre, which enables that the push-out of thinner position of the side wall of a product and the contact surface between the product and the inclined top are independently performed, ensures that the thinner position of the side wall of the product is not easy to deform and strain, and further enhances the product yield. The die structure comprises a front die, a rear die and an inclined top, wherein a cavity is formed between the front die and the rear die; the product is formed in the cavity; the upper part of the inclined top penetrates through the rear die, and then one side surface of the inclined top is adhered to the thinner wall of the side wall of the product; the structure is characterized in that the centre and a centre spring are arranged inside the inclined top; the front part of centre penetrates through the inclined top and then is propped against the thinner position of the side wall; a spring mounting groove is formed in the inclined top; the centre spring is positioned in the spring mounting groove; two ends of the centre spring are respectively propped against the front end surface of a bulge part at the tail of the centre and one side of the spring mounting groove close to the thinner position of the side wall.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially the mould structure that adds thimble in a kind of oblique top.
Background technology
The existing product of producing with mould, much all adopt oblique top mould unloading structure, but some product is thinner with the sidewall of inclined top face contact, during the demoulding, because product ejects, product and oblique top contact-making surface depart from simultaneously and occur, the power that makes the sidewall thin location of product simultaneously bear two side directions, makes sidewall thin location easily deform, pull, and makes the defect rate of product high.
Summary of the invention
The utility model provides the mould structure that adds thimble in a kind of oblique top, it departs from the ejecting of sidewall thin location, product and the oblique top contact-making surface of product to carry out separately respectively, guarantee that product sidewall thin location is difficult for deforming, pulling, and then the yields of improving product.
The mould structure that adds thimble in a kind of oblique top, its technical scheme is such: it comprises front mould, rear mold, oblique top, described front mould, it between rear mold, is die cavity, in described die cavity, it is product, described oblique top top is run through after described rear mold, the fit sidewall thin location of described product of one side, it is characterized in that: the inside of described oblique top is provided with thimble, thimble spring, the front portion of described thimble is mounted on described sidewall thin location after running through described oblique top, in described oblique top, have spring fitting groove, thimble spring is positioned at described spring fitting groove, the two ends of described thimble spring are mounted on respectively the tail protrusion portion front end face of described thimble, one side of the close described sidewall thin location of spring fitting groove, between the side away from described sidewall thin location of the tail protrusion portion rear end face of the described thimble under matched moulds state and described spring fitting groove, leave gap, the top of oblique top gathering sill end face is the arc structure away from described sidewall thin location, the mid portion of described oblique top gathering sill end face is vertical plane, the tail end of described thimble exposes to the another side of described oblique top, described in when matched moulds state and the not complete demoulding, the tail end of thimble is close to the vertical plane of the mid portion of described oblique top gathering sill end face.
It is further characterized in that: described oblique top is provided with wear-resistant block corresponding to described oblique top gathering sill endface position, described wear-resistant block, oblique top coordinate fastening installation to form spring fitting groove, and the tail end of described thimble exposes to described wear-resistant block and is close to the vertical plane of mid portion of the oblique top gathering sill end face of described rear mold.
Adopt after structure of the present utility model, not completely during the demoulding, the tail end of thimble is close to the mid portion of described oblique top gathering sill end face, the mid portion of oblique top gathering sill end face is vertical plane, its front portion that makes thimble is the sidewall thin location of sticky and product all the time, until after the complete demoulding, the tail end of thimble is along arc structure outwards motion under the pressure-acting of thimble spring of the sidewall thin location away from product, between the side away from sidewall thin location due to tail protrusion portion rear end face and described spring fitting groove, leave gap, it is the anterior indentation of thimble, oblique top continues to rise afterwards, product and oblique top contact-making surface are departed from, it makes the ejecting of sidewall thin location of product, product and the disengaging of oblique top contact-making surface are carried out separately respectively, guarantee that product sidewall thin location is difficult for deforming, pull, and then the yields of improving product.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
