Abstract
The utility model provides a spiral ejection mold structure. According to the structure, four products can be molded in a mold at a time, the production efficiency is improved, the labor time of a worker is saved, and the time and labor are reduced. The spiral ejection mold structure comprises a front mold, a rear mold, rear mold inserts and a plate B, wherein the rear mold inserts are inserts with external threads; the spiral ejection mold structure is characterized in that four cavities are formed between the front mold and the rear mold; the corresponding rear mold inserts are respectively positioned in the four cavities; the tail parts of the rear mold inserts penetrate through the rear mold and the plate B and are supported in a supporting cavity formed by an upper supporting plate and a lower supporting plate; a cavity is reserved between the upper supporting plate and the plate B; the rear mold inserts are respectively limited in the plate B through an upper sleeve; the tail parts of the rear mold inserts are respectively supported in the supporting cavity formed by the upper supporting plate and the lower supporting plate through a lower sleeve; an ejector pin through hole is formed in the center of the rear mold inserts; a product ejector pin penetrates through the ejector pin through hole and is propped against the corresponding cavity; the lower part of the product ejector pin is fastened to a mounting cavity formed by a surface pin plate and a bottom pin plate; a motion cavity is reserved between the lower supporting plate and the surface pin plate; the lower part of the bottom pin plate is connected with a top roller.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of spiral top mould unloading structure.
Background technology
Existing inwall is with the product of helicitic texture, it all has a die cavity is only set in a mould, threaded mold insert is placed in die cavity, and when the needs demoulding, guide pillar drives threaded mold insert to rotate, make product helical rotation depart from threaded mold insert, owing to only having a die cavity in a mould, it makes when this kind of product of a large amount of production of needs, and its production efficiency is low, need workman's working time long, waste time and energy.
Summary of the invention
The utility model provides a kind of spiral top mould unloading structure, and it makes in a mould can four products of one-shot forming, have improved production efficiency, has saved working time, time saving and energy saving of workman.
A kind of spiral top mould unloading structure, its technical scheme is such: it comprises front mould, rear mold, rear mold mold insert, B plate, described rear mold mold insert is for being with externally threaded mold insert, it is characterized in that: described front mould, between rear mold, form four die cavities, corresponding described rear mold mold insert lays respectively in four described die cavities, the afterbody of described rear mold mold insert runs through described rear mold, B plate rear support is in upper bearing plate, in the supporting cavity that lower support plate forms, between described upper bearing plate and described B plate, leave cavity, described rear mold mold insert is limited in described B plate by upper bush respectively, the afterbody of described rear mold mold insert is supported on described upper bearing plate by lower sleeve respectively, in the supporting cavity that lower support plate forms, the center of described rear mold mold insert has thimble through hole, product thimble is mounted on corresponding described die cavity after running through described thimble through hole, the bottom of described product thimble is anchored on face needle plate, in the formed installation cavity of end needle plate, between described lower support plate and described needle plate, leave motion cavity, the bottom of needle plate, the described end is connected with top roller, described in each, the position that is positioned at described cavity of rear mold mold insert is provided with identical gear structure, between two adjacent described gear structures, by travelling gear, connect, described travelling gear is set in the corresponding biography axle that turns, power transmission shaft described in one of them is driving shaft, its lower end is through to the output shaft of connection of rotating motor behind base plate lower end.
Adopt after structure of the present utility model, when front mould, after after moulding/demoulding, product thimble ejecting product upwards under the effect of top roller, electric machine rotation simultaneously, drives driving shaft to rotate and then driven shaft, gear structure rotate, make with rear thread, travelling gear drives corresponding rear mold mold insert to rotate, thereby makes product and rear mold mold insert complete the demoulding, and it makes in a mould can four products of one-shot forming, improve production efficiency, saved working time, time saving and energy saving of workman.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
