Above, the outside of side form and back side form before described location guide mechanism is arranged at is mainly used in the die sinking distance of side form and back side form before the control and drives ejecting mechanism, to eject the finished product in the die cavity.Ejecting mechanism is by ejecting element and drive unit is formed, and the described element that ejects comprises knock-pin and liftout plate.
Thereby pull bar moves back and forth in the middle of alignment pin, drives knock-pin and control die sinking distance thereby reach.In order to guarantee balance, can one group of described drag link mechanism be set respectively in the forward and backward side form outside; During die sinking, drive the pull bar motion by preceding side form, thereby alignment pin drives knock-pin, pushing-off product prevents that by stopping means liftout plate and back side form from bumping against, thereby has guaranteed the opening and closing of mould and ejected smooth and easy.
In the technique scheme, also be provided with heating arrangements and cooling body, described heating arrangements comprises a plurality of heating rods, evenly is arranged between die core and the die cavity; Described cooling body is located on the die core and is positioned at the front of heating rod.The setting of heating arrangements can better be controlled mold temperature, the outward appearance that makes finished product better, more attractive in appearance.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, die core of the present utility model and punch core cooperate a plurality of independently die cavitys of formation, cooperate flow passage system, can a shot generate many products, thereby improve production efficiency greatly, have reduced consumption, have reduced production cost.
2, location guide of the present utility model mechanism cooperates with ejecting mechanism, and the die sinking distance of side form and back side form before the control, not only is convenient to take out product, and can guarantees each surface quality of products and stability.
3, the heating arrangements of the utility model setting can better be controlled mold temperature, the outward appearance that makes finished product better, more attractive in appearance.
