Abstract
The utility model relates to a forming and angled ejecting device comprising a die, a plastic part, a die cavity plate, an angled ejector pin and a supporting plate, wherein the plastic part is arranged in a die cavity of the die; the die cavity plate is arranged at the bottom of the die; the upper end of the angled ejector pin is arranged in the plastic part after passing through the die cavity plate, and the lower end of the angled ejector pin is fixed on the supporting plate; the lower end of the angled ejector pin is provided with an arc-shaped pendulum; the bottom of the die cavity plate is provided with a clamping slot for containing a spring; and the spring is arranged on the angled ejector pin located between the die cavity plate and the supporting plate. Due to the arrangement of structures such as the angled ejector pin, the spring, the clamping slot, the arc-shaped pendulum and the like in the scheme, the plastic part is ejected out of the die when the die is opened, so that the forming and angled ejecting device is convenient and rapid in demoulding, simple in structure and also capable of improving the dimensional precision of the plastic part and meeting an appearance requirement.
Description
Technical field
The utility model relates to a kind of moulding oblique pushing device, belongs to injection mold technical field.
Background technology
In injecting products, can often run into some products, inner surface sidewall has localized indentation tongue or segmented thread etc., because its stripper distance is from generally all shorter, can greatly increase mould and manufacturing cost as loosed core with Angle Pin, therefore, need one can reduce costs and manufacture simple mechanism and solve the problems referred to above.
Utility model content
The utility model object is the moulding oblique pushing device that a kind of simple in structure, reliable in action is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of moulding oblique pushing device, comprises mould, plastic, cavity plate, slanted pushing rod, gripper shoe; Described plastic is arranged in the die cavity of mould; Described cavity plate is arranged on mold bottom; Described slanted pushing rod upper end is arranged in plastic through cavity plate, and lower end is fixed in gripper shoe; Described slanted pushing rod lower end is provided with arc centering block; Described cavity plate bottom is provided with the draw-in groove for placing spring; Described spring is arranged on the slanted pushing rod between cavity plate and gripper shoe.
Preferably, the surface hardening degree HRC>50 of described slanted pushing rod.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of moulding oblique pushing device of the utility model scheme, by slanted pushing rod, spring, draw-in groove, the isostructural setting of arc centering block, realizes mould in the time of die sinking, plastic is ejected in mould, be convenient in demoulding fast, simple in structure, can improve the modest ability precision of plastic simultaneously and meet shape requirement.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of a kind of moulding oblique pushing device of the present utility model;
Wherein: 1, mould; 2, plastic; 3, cavity plate; 4, slanted pushing rod; 5, gripper shoe; 6, arc centering block; 7, spring; 8, draw-in groove.
detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is a kind of moulding oblique pushing device described in the utility model, comprises mould 1, plastic 2, cavity plate 3, slanted pushing rod 4, gripper shoe 5; Described plastic 2 is arranged in the die cavity of mould 1; Described cavity plate 3 is arranged on mould 1 bottom; Described slanted pushing rod 4 upper ends are arranged in plastic 2 through cavity plate 3, and lower end is fixed in gripper shoe 5; Described slanted pushing rod 4 lower ends are provided with arc centering block 6; Described cavity plate 3 bottoms are provided with the draw-in groove 8 for placing spring 7; Described spring 7 is arranged on the slanted pushing rod 4 between cavity plate 3 and gripper shoe 5; The surface hardening degree HRC>50 of described slanted pushing rod 4.
Mould 1 is in the time opening, slanted pushing rod 4 ejects plastic 2 under ejection system effect, in ejection process, slanted pushing rod 4 end faces are done transverse movement along plastic 2 inner surfaces, meanwhile, slanted pushing rod 4 is also deviate from the concavo-convex place of sidewall gradually, finally completes the demoulding and moves and plastic 2 is deviate from, complete side and twitch and do, and then can complete product Automatic-falling with secondary ejecting mechanism; Slanted pushing rod 4 holds out against all the time in the draw-in groove 8 on cavity plate 3 bottoms under the effect of spring 7, when slanted pushing rod 4 transverse movement, under the effect of spring 7 and arc centering block 6, to left movement, arc centering block 6 plays the effect of fulcrum and swing, makes slanted pushing rod 4 keep the support to plastic 2 in transverse movement.
The utility model scheme is by slanted pushing rod 4, spring 7, draw-in groove 8, the isostructural setting of arc centering block 6, realize mould in the time of die sinking, plastic 2 is ejected in mould 1, be convenient in demoulding quick, simple in structure, can improve the modest ability precision of plastic simultaneously and meet shape requirement.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
