Abstract

The utility model provides a pitched roof structure for obliquely ejecting a die, which is used for molding a product with the circumferential side provided with holes and the inner circumferential side provided with a horizontal concave-convex structure and a vertical concave-convex structure by one time, is high in processing efficiency and improves the product efficiency. The pitched roof structure for the obliquely ejecting the die comprises a front die, a rear die, an actuator, a drag plate and an insert structure, wherein a hollow cavity formed by the front die, the rear die and the insert structure is a cavity. The pitched roof structure is characterized in that the insert structure comprises an outer-side insert, an inner-side insert and an inner-side pitched roof, the inner side of the outer-side insert is attached on the circumferential outer side structure of a product to be molded, the upper end surface of the outer-side insert is tightly attached on the lower end surface of the front die, the outer-side inclined surface of the outer-side insert is embedded in an inclined straight guide rail of the acuator, the inner-side insert is attached on the vertical concave-convex surface at the circumferential inner side of the product to be molded, the inner side of pitched roof at the inner side is attached on the horizontal concave-convex surface at the circumferential inner side of the product to be molded, and the inner-side insert is installed in a mounting groove of the pitched roof at the inner side.

Description

A kind of mould tiltedly eject ramp-roof structure

Technical field

The utility model relates to the technical field of structures of product mold, and what be specially a kind of mould tiltedly ejects ramp-roof structure.

Background technology

The inboard that has hole and a circumference for periphery has the product of level, vertical two concaveconvex structures, and existing mould can't one-shot forming, need accomplish the production of product through secondary operations, and its production efficiency is low and produce low precision.

Summary of the invention

What the utility model provided a kind of mould tiltedly ejects ramp-roof structure, and its inboard that makes circumference have hole and circumference has the product of level, vertical two concaveconvex structures can one-shot forming, and high and precision product of working (machining) efficiency is improved.

A kind of mould tiltedly eject ramp-roof structure; Its technical scheme is such: it comprises front mould, back mould, row position, planker, mold insert structure, and the cavity that said front mould, back mould, mold insert structure form is a die cavity, it is characterized in that: said mold insert structure comprises outside mold insert, inboard mold insert, interior skew back top; The fit periphery structure of product to be formed of the inboard of said outside mold insert; The lower surface of said front mould is close in the upper surface of said outside mold insert, and the inclined-plane, the outside of said outside mold insert is flush-mounted in the inclined-plane line slideway of said row position, said inboard mold insert fit product inside circumference to be formed vertically to male and fomale(M&F); The level of inside circumference of said product to be formed is fitted to male and fomale(M&F) in the inboard on skew back top in said; Said inboard mold insert is installed in the mounting groove on said interior skew back top, and in the guide-track groove on the outer inclined-plane of mould, the bottom surface on said interior skew back top was supported on planker after the outer inclined-plane on said interior skew back top was flush-mounted in; Leave the gap between said back mould and the said planker; The mounting groove inside on skew back top has oblique slotted hole in said, and said inboard mold insert is equipped with bearing pin, the said bearing pin during matched moulds be loaded in the said slotted hole and the said slotted hole of fitting near back mould side; The inboard of said back mould has one section vertical plane, and one section vertical plane of the said back mould of fitting is faced in the outside of said inboard mold insert directly.

After adopting the structure of the utility model, during the demoulding, rise in the row position; Under the pressure of front mould, outside mold insert can only move horizontally along the inclined-plane line slideway of row position, until accomplishing the pore space structure that outside mold insert breaks away from periphery; Afterwards, back mould descends, because the bottom surface on interior skew back top is supported on planker; Interior skew back roof pendant is directly motionless to temporarily, its along the back guide-track groove on outer inclined-plane of mould do level and inwardly shrink, this moment slotted hole also level inwardly shrink; Because one section vertical plane of the back mould of fitting is faced in the outside of inboard mold insert directly, bearing pin can only drive inboard mold insert and move vertically upward vertically to moving up; Accomplish until the inboard mold insert demoulding, this moment bearing pin be close to slotted hole away from back mould side, afterwards in the moving inboard mold insert level of skew back heading tape to inside contraction; Accomplish until the demoulding of interior skew back top, this moment, the back mould was pressed on planker, and back mould drive, interior skew back top, inboard mold insert, planker move downward together accomplishes the whole demoulding; Its inboard that makes circumference have hole and circumference has the product of level, vertical two concaveconvex structures can one-shot forming, and high and precision product of working (machining) efficiency is improved.
