Abstract
The invention provides a floating block compulsive demoulding structure. The floating block compulsive demoulding structure can be used for ensuring the simplicity of the demolding structure of a bottom edge inverse buckled product and reducing the cost of a mold. The floating block compulsive demoulding structure comprises a to-be-molded product, wherein the bottom edge of the product to be molded is of an inverse buckled structure, the height from the bottom end of the inverse buckled structure of the to-be-molded product to the vertical structure of a side transition structure of the to-be-molded product is L, a rear mold is arranged below the to-be-molded product, the bottom of an ejector rod is fastened on an integral structure of a face needle plate and a bottom needle plate, and the top of the ejector rod penetrates through the rear mold and is mounted on the to-be-molded product in an ejecting manner. The floating block compulsive demoulding structure is characterized in that the inner side of the floating block is adhered to the outer side of the rear mold, the inner side of the upper end of the floating block is clung to the end surface of the outer side of the inverse buckled structure, the floating block at a mold closing state is located in a mounting cavity formed by a plate A and a plate B and is supported on the plate B, and a spring mounting cavity is formed in a connecting part between the lower part of the floating block and the upper part of the plate B.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be specially a kind of rocker piece de-structure by force.
Background technology
Existing mold, for side direction back-off structure, generally adopts side slide block to carry out the demoulding, but for bottom margin torque product, adopts side slide block, the demoulding of Angle Pin structure, its complex structure, and the cost of mould is high.
Summary of the invention
The invention provides a kind of rocker piece de-structure by force, it makes the demolding structure of bottom margin torque product simple, has reduced the cost of mould.
A kind of rocker piece is de-structure by force, its technical scheme is such: it comprises product to be formed, the bottom margin of described product to be formed is back-off structure, the bottom of the back-off structure of described product to be formed is L to the height of the vertical stratification of its this side transition structure, the below of described product to be formed is rear mold, the bottom of push rod is anchored on face needle plate, the overall structure of end needle plate, the top of described push rod is mounted on described product to be formed after running through described rear mold, it is characterized in that: the fit outside of described rear mold, the inner side of rocker piece, the outside end face of back-off structure is close in the inner side, upper end of described rocker piece, described rocker piece under matched moulds state is positioned at A plate, in the installation cavity that B plate forms, described rocker piece is supported on described B plate, the bottom of described rocker piece, the link position on the top of B plate has spring fitting chamber, spring is positioned at described spring fitting chamber, described spring upper, lower end is mounted on respectively described rocker piece, B plate, the upper end of described rocker piece has vertically-guided groove, spacing guide rod runs through described vertically-guided groove from top to bottom, after rocker piece, be anchored on described B plate, the lower surface of the upper end head of described spacing guide rod and the lower surface of described vertically-guided groove distance are H, H > L wherein.
It is further characterized in that: described spacing guide rod runs through described spring fitting chamber, and described spring housing is loaded on described spacing guide rod.
Adopt after structure of the present invention, during mould die sinking, A plate, the separation of B plate, front mould, rear mold are simultaneously separated, and rocker piece is owing to being subject to the power of spring upwards moving, float to H apart from time, rocker piece is just motionless, due to H > L, give the strong de-space that stayed, push rod is top upwards, make back-off structure from completing separated with rocker piece, thereby completed product from mould whole action out, it makes the demolding structure of bottom margin torque product simple, has reduced the cost of mould.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises product 1 to be formed, the bottom margin of product 1 to be formed is back-off structure 2, the bottom of the back-off structure 2 of product 1 to be formed is L to the height of the vertical stratification of its this side transition structure, the below of product 1 to be formed is rear mold 3, the bottom of push rod 4 is anchored on face needle plate 5, the overall structure of end needle plate 6, the top of push rod 4 is mounted on product 1 to be formed after running through rear mold 3, the outside of the inner side laminating rear mold 3 of rocker piece 7, the outside end face of back-off structure 2 is close in the inner side, upper end of rocker piece 7, rocker piece 7 under matched moulds state is positioned at A plate 8, in the installation cavity that B plate 9 forms, rocker piece 7 is supported on B plate 9, the bottom of rocker piece 7, the link position on the top of B plate 9 has spring fitting chamber 10, spring 11 is positioned at spring fitting chamber 10, spring 11 upper, lower end is mounted on respectively rocker piece 7, B plate 9, the upper end of rocker piece 7 has vertically-guided groove 12, spacing guide rod 13 runs through vertically-guided groove 12 from top to bottom, after rocker piece 7, be anchored on B plate 9, the lower surface of the upper end head 14 of spacing guide rod 13 and the lower surface of vertically-guided groove 12 distance are H, H > L wherein.Spacing guide rod 13 runs through spring fitting chamber 10, and spring 11 is set in spacing guide rod 13.In figure, 14 is front mould.
