The rear-die slide block time-lapse core pulling mould structure comprises an A board, a B board, the front die and a rear die, a mould cavity is formed between the front die and the rear die, the product is in the mould cavity, the side part of the product is provided with the inner concave structure, the inner side of the side slide block goes deep into the inner concave structure, the outer side of the side slide block is fixedly connected with a slide block seat, the slide block seat is supported by the B board, the rear-die slide block time-lapse core pulling mould structure is characterized in that: a guide groove is arranged on a position of the slide block seat, and the position of the slide block seat is far away from the position of the slide block, the lower part of the guide groove is a top-down outward inclined plane with the slope of alpha, a guide post passes through the guide groove, and the guide post comprises an upper vertical part and a lower inclined guide part.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be specially a kind of rear mode slider time-delay drawing core mold structure.
Background technology
Large and its sidepiece of the upper surface area of some goods is provided with concave inward structure, existing mould structure it drive sidepiece slide block to move in front moulding/demoulding, because the contact area of front mould and goods is larger, and sidepiece slide block is separated with concave inward structure time, make easily sticky front mould of goods, and then it is separated to make goods need surcharge manpower, time and front mould to complete, make the production efficiency of mould low.
Summary of the invention
The invention provides a kind of rear mode slider time-delay drawing core mold structure; when large and its sidepiece of its upper surface area that makes goods is provided with concave inward structure; the front mould of mould, sidepiece slide block and goods complete the phenomenon that sticky front mould can not occur when separated; the demoulding is rapid, guarantees the production efficiency of mould.
A kind of rear mode slider time-delay drawing core mold structure, its technical scheme is such: it comprises A plate, B plate, front mould, rear mold, described front mould, between rear mold, form die cavity, in described die cavity, be goods, the sidepiece of described goods is provided with concave inward structure, described concave inward structure is goed deep in the inner side of sidepiece slide block, the outside of described sidepiece slide block is fastenedly connected take-up housing, described take-up housing is supported on described B plate, it is characterized in that: described take-up housing away from described sidepiece slide position, have gathering sill, the outer lower portion of described gathering sill is inclined-plane, described inclined-plane is specially outside inclined-plane from top to bottom, its gradient is α, in described gathering sill, be penetrated with lead, described lead comprises that upper vertical is to part, bottom inclined conducting divides, described bottom inclined conducting is divided into outward-dipping structure from top to bottom, its gradient is α, describedly vertically to part, be fastenedly connected described A plate, leaving apart from S between the inclined-plane, outside that the described inclined-plane under matched moulds state, bottom inclined conducting divide.
It is further characterized in that: described B plate is provided with spring groove, spring bead is positioned at described spring groove, the bottom face of the described take-up housing under matched moulds state is close to described spring bead, one side of the close described die cavity of described take-up housing is provided with spacing draw-in groove, and the described spring bead under demoulding state is mounted in described spacing draw-in groove completely;
Lower end, the outside buckle of described sidepiece slide block is in described take-up housing cladding embedding-and-buckling-structured, and the outer rear flank that bolt runs through described sidepiece slide block is from top to bottom anchored on described take-up housing;
Latch segment is fastenedly connected described A plate, and the outer upper inclined-plane of described take-up housing is close on the inclined-plane, inner side of described latch segment;
Described bottom inclined conducting divides and runs through the positioning chamber that is positioned at described B plate after described gathering sill.
Adopt after structure of the present invention, front mould, during rear moulding/demoulding, A plate, front mould rises, Angle Pin vertical lifting now, due to described inclined-plane under matched moulds state, leaving apart from S between the inclined-plane, outside that bottom inclined conducting divides, after distance H=S/Sin α that Angle Pin rises, after being front mould rising H, take-up housing just can horizontally outward drive the demoulding of sidepiece slide block under the drive of Angle Pin, when the initial demoulding of front mould, because the concave inward structure of goods is goed deep in sidepiece slide block inner side, it makes goods can not glue front mould in knockout course, and then the front mould of mould, sidepiece slide block and goods complete the phenomenon that sticky front mould can not occur when separated, the demoulding is rapid, guarantee the production efficiency of mould.
