Abstract
The invention provides a front-mould pin retraction structure of a three-plate mould. By means of the front-mould pin retraction structure, a product can not stick to a front mould during demoulding, and fewer burrs are generated on pore spaces of the product, so that the precision and the aesthetic property of the product are ensured. The front-mould pin retraction structure comprises a panel, a water gap plate, a plate A, a plate B, a front mould, a rear mould and an insert, wherein a mould cavity is formed among the front mould, the rear mould and the insert. The front-mould pin retraction structure is characterized in that a base plate and a carriage plate are arranged between the water gap plate and the front mould, the carriage plate is supported on the base plate, the insert is specifically an insert pin, the upper end of the insert pin is connected with the bottom end of the carriage plate in a fastening manner, the lower end of the insert pin penetrates through a through hole inside the base plate and then is arranged on a parting surface formed between the front mould and the rear mould in an ejection manner, the base plate is provided with a spring mounting through hole, a spring is mounted inside the spring mounting through hole, two ends of the spring are respectively arranged on the carriage plate and the front mould in an ejection manner, and the spring is sleeved on a connection bolt.
Description
Technical field
The present invention relates to the technical field of structures of stephanoporate product mold, be specially the 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 burr phenomenon at the hole place of product is obvious, causes the precision of product, aesthetics to descend.
Summary of the invention
The invention provides the front mould shortening structure of three template dies, product can not glue front mould during its demoulding, and the burr phenomenon at product hole place is few, guarantees precision, the aesthetics of product.
The front mould shortening structure of three template dies, it comprises panel, mouth of a river plate, the A plate, the B plate, front mould, back mould, mold insert, described front mould, back mould, form die cavity between the mold insert, it is characterized in that: described mouth of a river plate, backing plate is installed between the front mould, planker, described planker is supported on described backing plate, described mold insert is specially pin, described pin upper end is fastenedly connected the bottom of described planker, the lower end of described pin is mounted on described front mould after running through the through hole of described backing plate inside, the die joint that forms between the back mould, described backing plate has spring through hole is installed, spring is installed on described spring and installs in the through hole, the two ends of described spring are pushed up respectively and are adorned described planker, front mould, described spring housing is loaded on connecting bolt, the bolt head of described connecting bolt is positioned at the bottom mounting groove of described mouth of a river plate, the threaded portion of described connecting bolt runs through described planker successively, be anchored on described front mould behind the backing plate, have the gap between the bolt head bottom of the described connecting bolt during matched moulds and the end face of described planker.
After adopting structure of the present invention, during the demoulding, mouth of a river plate rises, because there is the gap in the end face of the bolt head of the described connecting bolt during matched moulds bottom and described planker, bolt can not drive backing plate rapidly, planker rises, make mouth of a river plate, there is the gap between 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, drives planker, backing plate, front mould, the A plate rises together, finishes the demoulding, because the pin elder generation demoulding, product can not glue front mould when making the demoulding, and the burr phenomenon at product hole place is few, guarantees the precision of product, aesthetics.
Description of drawings
Fig. 1 is a structural representation of the present invention.
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, front mould 5, back mould 6, form die cavity between the mold insert, in the die cavity is product 7, mouth of a river plate 2, backing plate 8 is installed between the front mould 5, planker 9, 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, the lower end of pin 10 is mounted on front mould 5 after running through the through hole of backing plate 8 inside, the die joint that forms between the back mould 6, backing plate 8 has spring through hole 11 is installed, spring 12 is installed on spring and installs in the through hole 11, dress planker 9 is pushed up at the two ends of spring 12 respectively, front mould 5, spring 12 is set in connecting bolt 13, the bolt head of connecting bolt 13 is positioned at the bottom mounting groove 14 of mouth of a river plate 2, and the threaded portion of connecting bolt 13 runs through planker 9 successively, be anchored on front mould 5 behind the backing plate 8, have the gap between the bolt head bottom of the connecting bolt 13 during matched moulds and the end face of planker 9.
