The front mould ramp-roof structure
The utility model relates to mould and tiltedly pushes up, and relates in particular to a kind of front mould ramp-roof structure.
In product structure, often run into the situation of button bit at front mould, the structure that at this moment must adopt the oblique top of front mould on the mould is to realize out button bit.Existing front mould ramp-roof structure is complicated, and the Mold Making cost is high, and fabrication cycle is long, and stability is bad, and operating process is loaded down with trivial details.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of front mould ramp-roof structure is provided.
For realizing above purpose, the technical scheme that the utility model adopts is:
A kind of front mould ramp-roof structure; Comprise top board, movable insert, guide finger and Xie Ding, also comprise the back mould mold insert that is connected with oblique top/bottom part, said guide finger is fixed in said top board; Said movable insert is socketed on the said guide finger slidably, and said Xie Ding top is connected with said movable insert.
Said oblique top/bottom part is fastened and connected mutually with back mould mold insert.
Be provided with two described guide fingers, be fixed in parallel to each other on the top board, said oblique top partly is connected with the movable insert that is between the two said guide fingers.
The beneficial effect of the utility model: simple in structure, cost is low, and the process-cycle is short, and stability is high; Operating process is simple, and production efficiency is high.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
Fig. 1 is the front view according to a kind of front mould ramp-roof structure matched moulds state of the utility model preferred embodiment.
Fig. 2 is the front view according to a kind of front mould ramp-roof structure die opening state of the utility model preferred embodiment.
The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of front mould ramp-roof structure is used for the go out button bit of button bit at front mould.Mould comprises upper mounted plate 11, solid plate 12, front mould 13, back mould 14, moving platen 15, thimble panel 16, Ejector Retainer Plate 17 and bottom plate 18.The front mould ramp-roof structure comprises top board 21, movable insert 22, two guide fingers 23, tiltedly pushes up 24 and back mould mold insert 25.Top board 21 is fixedly connected with solid plate 12.Two guide fingers 23 are fixed on the bottom of top board 21 parallel to each other.Movable insert 22 is socketed on two guide fingers 23, and can be along its upper and lower slip.Tiltedly top 24 is in front mould 13, and its upper end is connected with movable insert 22, and the lower end fastens mutually with back mould mold insert 25.
During die sinking, back mould mold insert 25 fastens oblique top 24 and moves downward, and tiltedly pushes up 24 and under gradient cooperates, moves to the dropout direction and take off button bit.The one section safe distance B that walks downward the again top 24 of retreading breaks away from back mould mold insert 25 fully.During matched moulds, tiltedly push up 24 and under mould 14 active forces of back, movable insert 22 up moved and reach the purpose that resets.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, make concrete change or change the protection domain that all belongs to the utility model.
