Description
Technical field
The utility model relates to a kind of mould structure of the secondary demoulding.
Background technology
Injection mold is produced similar round plastic part, such as lid, plate etc., on such working of plastics outer wall, be shaped with bulge loop or bead, after to working of plastics injection mo(u)lding, conventionally need stripper plate that working of plastics is released to de-material, but working of plastics by stripper plate after core is released, the bulge loop of working of plastics or bead are but still stuck on stripper plate, need to be taken off by workman, can not reach automatic demoulding.Such mould emptier, when mould is produced, not only loses time, and also can increase operative employee's labour intensity.And working of plastics easily produces distortion, breakage, cause working of plastics to scrap.
Existing secondary demolding structure adopts spring secondary demolding mechanism conventionally.In Fig. 1,1 is spring, and 2 is ejector pin retaining plate, and 3 and 5 is push rod, and 4 is core, and 6 is backing plate, and 7 is injector push rod, and the distance between backing plate 6 and ejector pin retaining plate 2 should be greater than the distance of releasing for the second time.During die sinking, after fixed and moving mould separates, injector push rod 7, backing plate 6 pass through push rod 5 by die cavity jack-up, plastic, by deviating from core 4, completes the demoulding for the first time, after this, the elastic force of spring 1 promotes ejector pin retaining plate 2, by push rod 3 by plastic by ejecting in die cavity, plastic is from free dropping in mould.The method is simple in structure, shortcoming be move not firm, the poor stability of frame for movement.
Utility model content
The utility model is the shortcoming that overcomes above-mentioned existing mold structure, provides a kind of stability better two push pedal secondary demolding structures.
The technical scheme that the utility model is realized goal of the invention employing is, a kind of pair of push pedal secondary demolding structure, comprise injector push rod, fixed die and dynamic model, described fixed die and dynamic model form product die cavity, described dynamic model comprises the first push pedal, the second push pedal, fixed head, portable plate, the first push rod, the second push rod and two swing hook parts, described the first push pedal and described fixed die matched moulds form product die cavity, described injector push rod is connected with described portable plate through described the second push pedal, one end of described the first push rod is fixed in the second push pedal, the other end is successively through described portable plate, described fixed head is connected to described the first push pedal, described second push rod one end is fixed on described portable plate, the other end is connected to product die cavity through described fixed head and described the first push pedal successively, the middle part of two described swing hooks is all fixed on described portable plate by rotating shaft, one end of described swing hook is circle hook portion, the other end is wedge-shaped part, the wedge-shaped part of two described swing hooks connects by spring, in described the second push pedal, the round hook portion of corresponding described two swing hooks is provided with two hook posts, on described fixed head, be provided with clapboard, the wedge-shaped part of corresponding described two swing hooks of described clapboard is provided with two inclined-planes.
Particularly, two described swing hooks are arranged on the side of described portable plate, and described clapboard correspondence is arranged on the side of fixed head.
The beneficial effects of the utility model are: the utility model provides a kind of pair of push pedal secondary demolding structure, and the design by two push pedals and swing hook realizes the secondary demoulding, have overcome the not shortcoming of firm poor stability of existing secondary demolding structure action.
Accompanying drawing explanation
Fig. 1, the structure cutaway view of existing secondary demolding structure.
Fig. 2, structure cutaway view during embodiment matched moulds.
Fig. 3, the section of structure after the embodiment demoulding for the first time.
Fig. 4, the section of structure after the embodiment demoulding for the second time.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Structure cutaway view when accompanying drawing 2 is the present embodiment matched moulds, comprise injector push rod 7, fixed die (not shown) and dynamic model, fixed die and dynamic model form product die cavity, after matched moulds, product mould intracavitary administration forms product 8, dynamic model comprises the first push pedal 9, the second push pedal 10, fixed head 11, portable plate 12, the first push rod 13, the second push rod 14 and two swing hook parts 15, the first push pedal 9 forms product die cavity with fixed die matched moulds, injector push rod 7 is connected with portable plate 12 through the second push pedal 10, one end of the first push rod 13 is fixed in the second push pedal 10, the other end is successively through portable plate 12, fixed head 11 is connected to the first push pedal 9, second push rod 14 one end are fixed on portable plate 12, the other end is connected to product die cavity through fixed head 11 and the first push pedal 9 successively, the middle part of two swing hooks 15 is all fixed on portable plate 12 by rotating shaft 16, one end of swing hook is circle hook portion 15a, the other end is wedge-shaped part 15b, the wedge-shaped part 15b of two swing hooks 15 connects by spring 1, in the second push pedal 10, the round hook portion 15a of corresponding two swing hooks 15 is provided with two hook posts 17, on fixed head 11, be provided with clapboard 18, the wedge-shaped part 15b of clapboard 18 corresponding two swing hooks 15 is provided with two inclined-plane 18a.
