Abstract
The utility model provides a front mold structure capable of closing up from two sides and demolding inwards. A product which is provided with an inner hole at the upper part can be formed in the mold once, so that the precision of the product is improved and the production efficiency of the product is improved, wherein the inner cavity of the inner hole is greater than the diameter of the inner hole. The front mold structure comprises a front mold, a rear mold, mold inserts at two sides and a front mold insert, wherein a cavity is formed among the front mold, the rear mold, the mold inserts at two sides and the front mold insert; the product is arranged in the cavity; the front mold structure is characterized in that the front mold insert comprises a center insert and a side insert, the bottom of the center insert is closely attached on the lower inner wall of the inner cavity of the cavity, two sides of the center insert are inclined surfaces which are closed up inwards from top to bottom, the inner sides of the two side inserts are transitional inclined surfaces, and the transitional inclined surfaces of the side inserts are correspondingly attached to the inclined surfaces of the center insert respectively.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of front mould both sides inside demolding structure that closes up.
Background technology
The inner chamber that existing mould has endoporus and an endoporus for top is greater than the product in endoporus aperture, need to add inner-cavity structure by post forming, because post forming needs secondary location, it makes the low precision of product, and post-forming process makes the production efficiency of product low.
Summary of the invention
The utility model provides a kind of front mould both sides inside demolding structure that closes up, and its inner chamber that makes top have endoporus and endoporus is greater than the product in endoporus aperture can one-shot forming in mould, has improved the precision of product, and has promoted the production efficiency of product.
Inside demolding structure closes up in a kind of front mould both sides, its technical scheme is such: it comprises front mould, rear mold, both sides mold insert, front mould mold insert, described front mould, rear mold, both sides mold insert, between front mould mold insert, form die cavity, in described die cavity, it is product, the top of described product has endoporus, and the inner chamber of endoporus is greater than endoporus aperture, it is characterized in that: described front mould mold insert comprises center mold insert, sidepiece mold insert, the lower inwall of the inner chamber of described die cavity is close in the bottom of described center mold insert, the both sides of described center mold insert are the inclined-plane inwardly closing up from top to bottom, the inner side of two described sidepiece mold inserts is transition inclined-plane, fit the respectively corresponding inclined-plane of described center mold insert, the transition inclined-plane of described sidepiece mold insert, the corresponding sidewall of described inner chamber is close to respectively in the outside of described sidepiece mold insert, the lower surface, top of described sidepiece mold insert is supported on respectively the respective side of the upper end of described front mould, between the upper surface, top of every described sidepiece mold insert and described backing plate, be provided with spring structure, the top of the sidepiece mold insert described in every is provided with intilted inclined guide groove from top to bottom, panel is fastenedly connected the upper end of described center mold insert, described panel is supported on described backing plate, described backing plate is supported on described A plate, two outsides of mold insert upper end, described center are respectively arranged with guide plate, the top of every described guide plate is fastenedly connected respectively described panel, the bottom of every described guide plate is Angle Pin, described Angle Pin slopes inwardly from top to bottom, the Angle Pin correspondence of described guide plate is positioned in the top locating slot of described front mould after being plugged in the inclined guide groove of the described sidepiece mold insert under it.
Adopt after structure of the present utility model, panel, backing plate rises, drive center mold insert, guide pad rises, due to the existence of spring structure, sidepiece mold insert temporarily cannot on move, the Angle Pin of guide pad drives respectively corresponding sidepiece mold insert to move inward, until the part of being close to respective sides of sidepiece mold insert move to endoporus under, now the active force of spring structure is less than the upwards tractive force of lead for sidepiece mold insert, the demoulding of having risen of sidepiece mold insert, it makes top have endoporus, and the inner chamber of endoporus is greater than the product in endoporus aperture can one-shot forming in mould, improve the precision of product, and promote the production efficiency of product.
