Abstract

The utility model provides a front mould shortening structure of a three-plate mould. A product cannot be adhered to a front mould when demoulding, so that the phenomenon of rough edges at a hole of the product is reduced, and the accuracy and appearance degree of the product can be guaranteed. The front mould shortening structure of the three-plate mould comprises a panel, a top clamp plate, an A plate, a B plate, a front mould, a rear mould and an insert; the front mould, the rear mould and the insert form a cavity; the front mould shortening structure of the three-plate mould is characterized in that a cushion plate and a carriage are arrange between the top clamp plate and the front mould; the carriage is supported on the cushion plate; the insert is specifically an insert pin; the upper end of the insert pin is connected with the bottom end of the carriage in a fastening way; the lower end of the insert pin penetrates through a through hole inside the cushion plate to be jacked in a mould joint formed between the front mould and the rear mould; the cushion plate is provided with a spring installation through hole; a spring is arranged in the spring installation through hole; the two ends of the spring respectively jack the carriage and the front mould; and the spring is sheathed in a connecting bolt.

Description

A kind of front mould shortening structure of three template dies

Technical field

The utility model relates to the technical field of structures of stephanoporate product mold, is specially a kind of front mould shortening structure of three template dies.

Background technology

Existing porous surface product mold when the demoulding, produces the phenomenon of gluing front mould through regular meeting, and the blurred at the hole place of product is obvious, causes the precision of product, aesthetics to descend.

Summary of the invention

The utility model provides a kind of front mould shortening structure of three template dies, and product can not glue front mould during its demoulding, and the blurred at product hole place is few, guarantees precision, the aesthetics of product.

A kind of front mould shortening structure of three template dies, it comprises panel, mouth of a river plate, A plate, B plate, front mould, back mould, mold insert, forms die cavity between said front mould, back mould, the mold insert; It is characterized in that: between said mouth of a river plate, the front mould backing plate, planker are installed; Said planker is supported on said backing plate, and said mold insert is specially pin, and said pin upper end is fastenedly connected the bottom of said planker; The lower end of said pin is mounted on the die joint that forms between said front mould, the back mould after running through the inner through hole of said backing plate; Said backing plate has the spring installation through holes, and spring is installed in the said spring installation through holes, and the two ends of said spring are pushed up respectively and adorned said planker, front mould; Said spring housing is loaded on connecting bolt; The bolt head of said connecting bolt is positioned at the bottom mounting groove of said mouth of a river plate, and the threaded portion of said connecting bolt is anchored on said front mould after running through said planker, backing plate successively, has the gap between the bolt head bottom of the said connecting bolt during matched moulds and the end face of said planker.

After adopting the structure of the utility model, during the demoulding, mouth of a river plate rises; Because there is the gap in the end face of the bolt head of the said connecting bolt during matched moulds bottom and said planker, bolt can not drive backing plate rapidly, planker rises, and makes to have the gap between mouth of a river plate, the planker; The elastic force of spring makes planker rise, because the pin upper end is fastenedly connected the bottom of planker, the lower end of pin breaks away from the product of die joint after breaking away from moulding; At this moment the end face of planker is close in the bolt head of connecting bolt bottom, and drive planker, backing plate, front mould, A plate rise together, accomplish the demoulding; Because the pin elder generation demoulding; Product can not glue front mould when making the demoulding, and the blurred at product hole place is few, guarantees precision, the aesthetics of product.

Fig. 1 is the structural representation of the utility model.

The specific embodiment

See Fig. 1, it comprises panel 1, mouth of a river plate 2, A plate 3, B plate 4, front mould 5, back mould 6, mold insert, forms die cavity between front mould 5, back mould 6, the mold insert; In the die cavity is product 7, and backing plate 8, planker 9 are installed between mouth of a river plate 2, the front mould 5, and planker 9 is supported on backing plate 8; Mold insert is specially pin 10; Pin 10 upper ends are fastenedly connected the bottom of planker 9, and the die joint that is mounted on front mould 5, afterwards forms between the mould 6 behind the through hole of backing plate 8 inside is run through in the lower end of pin 10, and backing plate 8 has spring installation through holes 11; Spring 12 is installed in the spring installation through holes 11; The two ends of spring 12 are pushed up dress planker 9, front mould 5 respectively, and spring 12 is set in connecting bolt 13, and the bolt head of connecting bolt 13 is positioned at the bottom mounting groove 14 of mouth of a river plate 2; The threaded portion of connecting bolt 13 is anchored on front mould 5 after running through planker 9, backing plate 8 successively, has the gap between the bolt head bottom of the connecting bolt 13 during matched moulds and the end face of planker 9.
