Abstract
The invention provides an internal line ejecting structure, which can release a buckle from a buckling position during die splitting, eject a product completely and realize convenient demolding of the product with a bayonet. The structure comprises a slide block, a taper pin, an upper die, a lower die and a push plate die, wherein the taper pin passes through the slide block through an inclined hole and is fixedly arranged on the lower die. The structure is characterized in that: a slide block insert is arranged in the slide block; the taper pin has a concave inclined surface; and the concave inclined surface on the taper pin is matched with the inclined surface of the inclined hole on the slide block.
Description
Technical field
The present invention relates to the technical field of row position design, be specially roof construction in the row position.
Background technology
The inboard of product is provided with buckle, and the buckle place can't take off by force when dividing mould, because other position distances of buckle and product are too near, also can't use oblique top to eject.
Summary of the invention
At the problems referred to above, the invention provides a roof construction in a kind of row position, can when minute mould, break away from button bit to buckle, product is intactly ejected.
Its technical scheme is such: roof construction in a kind of row position, it comprises slide block, taper pin, upper die and lower die and push pedal mould, described taper pin passes slide block by inclined hole and is fixedly mounted on the counterdie, it is characterized in that: described slide block is equipped with the slide block mold insert, described taper pin is concave slope, has the inclined-plane of the inclined hole on concave slope and the described slide block to cooperate on the described taper pin.
In the said structure of the present invention, there is the inclined-plane of the inclined hole on concave slope and the described slide block to cooperate on the taper pin owing to adopted, concave slope extruding slide block is arranged on the taper pin during slide block movement, thereby make slide block produce displacement, drive the slide block mold insert buckle place of product is broken away from button bit, continuation ejects product, realizes the conveniently stripped of band bayonet socket product.
Description of drawings
Fig. 1 is roof construction schematic diagram in the present invention's row position.
The specific embodiment
See Fig. 1, roof construction comprises patrix 8 in the present invention's row position, counterdie 6, push pedal mould 7 and slide block 9, taper pin 10 is fixedly mounted on the counterdie 6, slide block mold insert 2 is installed on the slide block 9, inclined hole 5 is arranged on the slide block 9, and taper pin 10 inserts in the inclined hole 5 on the slide blocks, has the inclined-plane of the inclined hole on concave slope 4 and the slide block to cooperate on the taper pin, after the die sinking, patrix 8 separately drives slide block 9 motions, because the effect of concave slope 4 is arranged on the taper pin, extruding slide block 9 moves inwards, the mold insert 2 that slide block 9 drives on the slide block moves inwards, and extruded product 1 is threaded off product buckle place by force, when continuing to divide mould product 1 is ejected, finish the back-off demoulding.
Claims (1)
1. a roof construction in the row position, it comprises slide block, taper pin, upper die and lower die and push pedal mould, described taper pin passes slide block by inclined hole and is fixedly mounted on the counterdie, it is characterized in that: described slide block is equipped with the slide block mold insert, described taper pin is concave slope, has the inclined-plane of the inclined hole on concave slope and the described slide block to cooperate on the described taper pin.
