Description
Technical field
The utility model is related to auto parts mould applications, more particularly to a kind of bumper skew back roof construction.
Background technology
In the general largest contours line position in product of existing technology China and foreign countries division buffer bar mould trip positions, mould
Can directly it mold, in terms of mould structure simply processing.But can leave parting line in product die joint position.And at this position
It is product appearance viewing position, the appearance effects to vehicle are just very big, so if die joint can be made to be located at interior parting portion
Position can then greatly improve the good appearance degree of product, can in the die sinking of parting mould need the deformation of product to coordinate, therefore need
Design a Slanted ejecting component that when molding ejection product can be made to draw deformation.
In the prior art, Slanted ejecting component uses the guide rail that beryllium copper material is made, expensive, and guide rail takes the oblique top back of the body
Space of planes is big, influences the back-supported of oblique top, easily produces jacking block print, and high processing costs.
Utility model content
In order to solve problem of the prior art, the utility model provides a kind of bumper skew back roof construction, reduce cost,
Simplify structure, shorten the process-cycle, improve product surface quality.The technical scheme is as follows：
The utility model provides a kind of bumper skew back roof construction, including base push pedal, push rod, core, big oblique top, small
Oblique top and small oblique top slide bar, the base push pedal are provided with fixing groove, and the bottom of the push rod passes through fastening rib and base push pedal
Fixed, the top of the push rod is stretched into the core, and be connected with one end of the small oblique top slide bar, the push rod with it is small oblique
Top slide bar is vertically arranged, and the other end of the small oblique top slide bar is connected with small oblique top, and the big oblique top is arranged on the outside of small oblique top
And ejection synchronous with the generation of small oblique top, the top of the push rod is provided with guide ledges, the small oblique top along small oblique top slide bar to
Guide ledges direction is ejected, and the sectional area of the push rod is less than 3 cm2, the footprint of the guide ledges is less than 1cm2。
Preferably, push rod is made of SUJ2 materials.
Specifically, the top surface of the big oblique top is ramp structure.
Further, the cavity wall of the core is provided with least one guide link.
What the technical scheme that the utility model is provided was brought has the beneficial effect that：
a）Beryllium copper guide rail is changed to the common push rods of SUJ2, material cost is saved.
b）The space that the common push rods of SUJ2 take is more much smaller than beryllium copper guide rail, increases oblique top back-supported area, increases
The stability that oblique top coordinates, while the risk of less bumper jacking block print.
c）Processing is easier to, conveniently, and labor content is substantially reduced.
d）New departure operation principle：During mould ejection, push rod, big oblique top, small oblique top are ejected together, in ejection process,
Small lifter ejection direction is ejected by push rod boss, and small slant-top core-pulling direction is oriented to by push rod boss.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the utility model embodiment
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
