Abstract
The utility model provides a front mold demoulding structure which enables a product to be ejected automatically in a front mold demoulding process, so that automatic separation is finished and the production efficiency of a mold is high. The front mold demoulding process comprises a front mold, a rear mold, a rear mold insert, a plate A and a plate B, wherein a cavity is formed between the front mold, the rear mold and the rear mold insert. The front mold demoulding structure is characterized in that the front mold is located in a mounting cavity of the plate A and is in fastening connection with the plate A, an ejector plate mounting groove is formed in the upper part of the front mold, an ejector plate comprises an upper horizontal section and a lower vertical section and is supported in the ejector plate mounting groove in a corresponding shape, a gap is reserved between the lower end surface of the upper horizontal section of the ejector plate and a corresponding lower plane of the ejector plate mounting groove, the upper part of a guide post is top-mounted at the lower end of the upper horizontal section of the ejector plate, the lower part of the guide post penetrates through the front mold and top-mounted to the rear mold, the upper end surface of the upper horizontal section of the ejector plate is closely attached to the lower end surface of the plate A, a spring mounting groove is located between the upper horizontal section of the ejector plate and the plate A, a spring is mounted in the spring mounting groove, and upper and lower end surfaces of the spring are top-mounted to the plate A and the ejector plate.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of structure of de-front mould.
Background technology
Mode structure before existing mould de-, it completes after the demoulding generally all and product conglutinate, needs the extra separation of manually carrying out, and makes the production efficiency of mould low.
Summary of the invention
The utility model provides a kind of structure of de-front mould, and it makes can automatically product be ejected in front mould knockout course, completes automatic separation, makes the production efficiency of mould high.
A kind of structure of de-front mould, its technical scheme is such: it comprises front mould, rear mold, rear mold mold insert, A plate, B plate, described front mould, rear mold, between rear mold mold insert, form die cavity, it is characterized in that: described front mould is positioned at the installation cavity of described A plate, described front mould is fastenedly connected described A plate, the top of described front mould is provided with ejector retainner plate mounting groove, ejector retainner plate comprises upper level part, bottom vertical portion, ejector retainner plate is supported in the ejector retainner plate mounting groove of correspondingly-shaped, the lower surface of the upper level part of described ejector retainner plate and the corresponding lower flat of ejector retainner plate mounting groove leave gap, the top of guide pillar is mounted on the lower end of the upper level part of described ejector retainner plate, the bottom of described guide pillar is mounted on described rear mold after running through front mould, the lower surface of described A plate is close in the upper surface of the upper level part of described ejector retainner plate, spring fitting groove is positioned at the upper level part of described ejector retainner plate, between A plate, spring fitting is in described spring fitting groove, described spring upper, lower surface is mounted on respectively described A plate, ejector retainner plate.
Adopt after structure of the present utility model, during front moulding/demoulding, the moving front mould of A strip rises, now spring-force driven dual is in ejector retainner plate, and guide pillar is supported on rear mold, the lower surface of the upper level part of ejector retainner plate and the corresponding lower flat of ejector retainner plate mounting groove leave gap, ejector retainner plate does not rise, the bottom vertical portion of ejector retainner plate is withstood the product in die cavity, front mould and separation of products, afterwards when front mould is close to behind the lower surface of upper level part of ejector retainner plate, ejector retainner plate rises, make the lower vertical of ejector retainner plate partly depart from product, it makes can automatically product be ejected in front mould knockout course, complete automatic separation, make the production efficiency of mould high.
