Abstract
The utility model discloses an inclined ejection block mechanism, which comprises a convex die with an inclined slot, an inclined ejection block with a concave buckle, a swing rod, a base and an ejection system. The inclined ejection block is arranged in the inclined slot of the convex die, the upper end of the swing rod is connected with the bottom of the inclined ejection block in a rotating way, the lower end of the swing rod is connected with the upper end of the base in a rotating way, and the ejection system is used for ejecting the base upwards. The utility model has the advantages that the die structure only occupies small space, and the weight of the die is greatly reduced.
Description
Technical field
The utility model relates to a kind of slanted kicking block mechanism.
Background technology
See Fig. 1 and Fig. 2, in a lot of plastic products and Al-alloy products, often there is the structure of back-off the inboard of product.For product is successfully separated from the model of mould, generally adopt the structure of slanted kicking block.At first the punch of mould is made the structure of band skewed slot, goods are after moulding in the mould, and moving, cover half separates, and the ejection system of injection machine or die casting machine pushes the push pedal of mould, and at this moment, the tilted footstock of the band chute in the push pedal can promote slanted kicking block and move forward.Because the effect of skewed slot, slanted kicking block can move along the direction of skewed slot, ejects product, and the moving of the level of generation, make back-off on the product and the recessed deduction of points on the slanted kicking block from.There are some inevitable defectives in this structure: the space that 1, accounts in mould is big, and when having the many places back-off simultaneously on the product, it is very big that mould can be done.Or interfere mutually between a plurality of slanted kicking blocks, the designer be forced to slanted kicking block do very thin, cause the intensity of slanted kicking block to reduce, have a strong impact on the service life of mould; 2, because the moving horizontally of slanted kicking block, the faying face of slanted kicking block and the tilted footstock of band chute makes the maintenance load of mould increase because the plucking phenomenon appears in friction easily.
The utility model content
The purpose of this utility model is to provide a kind of slanted kicking block mechanism, and is simple in structure, effectively reduces the weight and the occupation space of mould, thoroughly avoids the appearance of plucking phenomenon.
The technical scheme that realizes the utility model purpose is: a kind of slanted kicking block mechanism, comprise punch that is provided with skewed slot and the slanted kicking block that is provided with recessed button, also comprise fork, base and ejection system, slanted kicking block is positioned at the skewed slot of punch, the upper end of fork and the bottom of slanted kicking block are rotationally connected, the lower end of fork and the upper end of base are rotationally connected, and ejection system is used for upwards pushing base.
The top and bottom of described fork all are rotationally connected with the bottom of slanted kicking block and the upper end of base respectively by rotating shaft.
The utlity model has following beneficial effect: the upper end of (1) the utility model fork and the bottom of slanted kicking block are rotationally connected, the lower end of fork and the upper end of base are rotationally connected, the space that this structure makes the utility model occupy in mould structure is less, has significantly reduced the weight of mould.
(2) ejection system of the present utility model is used for upwards pushing base, owing to there is not frictional force, therefore this structure has thoroughly avoided slanted kicking block and base friction the plucking phenomenon to occur.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the structural representation of existing slanted kicking block mechanism.
Structural representation when Fig. 2 ejects for existing slanted kicking block mechanism.
Fig. 3 is a structural representation of the present utility model.
Structural representation when Fig. 4 ejects for the utility model.
Label is in the accompanying drawing:
Punch 1, skewed slot 11, slanted kicking block 2, recessed button 21, fork 3, rotating shaft 31, base 4.
The specific embodiment
(embodiment 1)
See Fig. 3 and Fig. 4, present embodiment comprises punch 1, slanted kicking block 2, fork 3, base 4 and ejection system.
Punch 1 is provided with skewed slot 11, slanted kicking block 2 is provided with recessed button 21, and slanted kicking block 2 is positioned at the skewed slot 11 of punch 1, and the upper end of fork 3 is rotationally connected by the bottom of rotating shaft 31 with slanted kicking block 2, the lower end of fork 3 is rotationally connected by the upper end of rotating shaft 31 with base 4, and ejection system is used for upwards pushing base 4.
When the ejection system of injection machine or die casting machine pushes base 4, base 4 promotes fork 3 and slanted kicking block 2, make slanted kicking block 2 move forward along the skewed slot 11 of punch 1, at this moment fork 3 is that the center of circle turns over an angle with rotating shaft 31 in the neutral of the skewed slot 11 of punch 1, and make slanted kicking block 2 produce one and move horizontally, make product separate smoothly with model.
Should be appreciated that specific embodiment described above only is used to explain the utility model, and be not used in qualification the utility model.Conspicuous variation of being extended out by spirit of the present utility model or change still are among the protection domain of the present utility model.
