A product with a horizontal inward protrusion on the inner side of the front part can be subjected to one-step injection molding, the production efficiency of the product is improved, and the processing precision of the product is high. The core-pulling structure comprises a front die and a rear die, wherein a cavity is formed between the front die and the rear die; the product is arranged in the cavity; a horizontal inward protrusion is arranged on the front inner side of the product; the core-pulling structure is characterized by comprising a front die slide block insert, wherein the outer side of the lower end of the front die slide block insert stretches into the inner side of the horizontal inward protrusion of the product; a lower end face of the front die slide block insert is tightly attached to the cavity; the outer side of the upper end of the front die slide block insert is supported to the front die; an upper end face of the front die slide block insert is tightly attached to a lower end face of a plate A; an inner side face of the front die slide block insert is an inner side inclined surface which is inclined outwards from bottom to top; a shoveling machine is positioned in a mounting cavity of the front die.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of pulled core structure of front mode slider mold insert.
Background technology
Before the front mould slipper block loose core of existing mold all drives by shovel structure, mode slider is done horizontal demoulding campaign; it is all that front mode slider level is away from the motion of die cavity; but for anterior inner side with level to projecting inward product; existing front mould slipper block loose core cannot meet the one-time formed requirement of product; it makes product needed carry out secondary operations; reduce the production efficiency of product, and due to secondary location, made the machining accuracy of product low.
Summary of the invention
The utility model provides a kind of pulled core structure of front mode slider mold insert, and it makes the anterior inner side can single injection-molded to projecting inward product with level, has improved the production efficiency of product, and has made the machining accuracy of product high.
A kind of pulled core structure of front mode slider mold insert, its technical scheme is such: it comprises front mould, rear mold, described front mould, between rear mold, form die cavity, in described die cavity, it is product, the anterior inner side of described product with level to projecting inward, it is characterized in that: it also comprises front mode slider mold insert, the level that described product is goed deep in the outside, lower end of described front mode slider mold insert is to projecting inward inner side, described die cavity is close in the lower surface of described front mode slider mold insert, the outside, upper end of described front mode slider mold insert is supported on described front mould, the lower surface of A plate is close in the upper surface of described front mode slider mold insert, the medial surface of described front mode slider mold insert is from bottom to top outward-dipping inclined-plane, inner side, shovel is positioned at the installation cavity of described front mould, the inclined-plane, inner side of described front mode slider mold insert is close on the inclined-plane, outside of described shovel, inclined-plane, described inner side is by the described shovel of the spacing connection of T-shaped groove structure, the lower surface of described A plate has stopper slot corresponding to described shovel position, the top of described shovel is positioned at the lower position of described stopper slot, between the upper surface of described shovel and the upper surface of described stopper slot, leave distance D, water gap plate press-fits in described A plate, on described water gap plate, have installing hole, stop screw runs through described installing hole from top to bottom successively, A plate, after stopper slot, be fastenedly connected described shovel, longitudinal spring is set in described stop screw, described longitudinal spring upper, lower end is mounted on respectively the head lower surface of described stop screw, the upper surface of A plate, described longitudinal spring is positioned at described installing hole, the upper surface of the head of the described stop screw under matched moulds state is mounted on panel.
It is further characterized in that: between longitudinal contact-making surface of described front mode slider mold insert and described front mould, be provided with crossed strip.
Adopt after structure of the present utility model, panel rises, under longitudinal spring effect, stop screw rises, drive shovel to rise simultaneously, because inclined-plane, inner side is close on the inclined-plane, outside of shovel, the inclined-plane, inner side of front mode slider mold insert is by the spacing connection shovel of T-shaped groove structure, the inside horizontal movement of mode slider mold insert before shovel drives, make front mode slider mold insert and die cavity complete the demoulding, afterwards, after complete the demoulding, product is ejected by thimble, it makes the anterior inner side can single injection-molded to projecting inward product with level, improved the production efficiency of product, and make the machining accuracy of product high.
