Description

Without the need to the injection mold of twice-die-opening

Technical field

The utility model relates to a kind of injection mold, particularly relates to a kind of injection mold without the need to twice-die-opening.

Background technology

The structure of the plastic product on existing market becomes increasingly complex, many plastic products all have inside groove, thus require that mould also has can the structure of this inside groove of injection moulding, this just requires has a kind of structure that mould is extracted out from inside groove that can be intact, but this mould of can extracting out quickly and easily has certain difficulty, and this respect is also those skilled in the art's problem to be solved always.Mostly adopt repeatedly die sinking in prior art, core that the mode of repeatedly loosing core will be in different directions groove extracts out, just complicated many in technique and structure like this, be also unfavorable for producing in enormous quantities.

Summary of the invention

The purpose of this utility model is to provide short, reliable in action, structure of a kind of formed product cycle simply without the need to the injection mold of twice-die-opening.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of injection mold without the need to twice-die-opening, comprises panel, cover half fixed head, front cavity, dynamic mould fixing plate, rear cavity, thimble, top board, mould pin, base plate, core-pulling mechanism; Described panel, cover half fixed head, dynamic mould fixing plate are superimposed together successively, front cavity as a die cavity part is arranged in cover half fixed head, rear cavity as a die cavity part is arranged in dynamic mould fixing plate and rear cavity is relative with front cavity, thimble activity is located in dynamic mould fixing plate and rear cavity, die cavity is stretched in one end of thimble, the other end of thimble is fixed on top board, and top board is arranged between dynamic mould fixing plate and base plate, and dynamic mould fixing plate is connected by mould pin with base plate;

Described core-pulling mechanism comprises oil cylinder of loosing core, connector, self-locking block, front mold slide; The cylinder body of described oil cylinder of loosing core is fixed on the sidewall of cover half fixed head; the piston rod of oil cylinder of loosing core stretches into cover half fixed head; the piston rod of oil cylinder of loosing core is connected with the connector one end of slipping in cover half fixed head; the connector other end is provided with slide rail and is fixed with self-locking block; the chute of front mold slide one end to slip on the slide rail of connector and the draw-in groove of this end of front mold slide and self-locking block holding, and the front mold slide other end stretches into die cavity.

After adopting such scheme; because the utility model has the core-pulling mechanism be made up of parts such as oil cylinder of loosing core, connector, self-locking block, front mold slide; before die sinking; front mold slide can be detached die cavity by oil cylinder of loosing core; complete action of loosing core; save twice-die-opening action, formed product cycle time, reduces cost.In addition, the utility model is provided with slide block self-locking mechanism (self-locking block), avoids because briquetting pressure makes slide block retreat defects such as causing formed product bad, makes the utility model action more reliable.Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Detailed description of the invention

As shown in Figure 1, the utility model is a kind of injection mold without the need to twice-die-opening, comprises panel 1, cover half fixed head 2, front cavity 3, dynamic mould fixing plate 4, rear cavity 5, core-pulling mechanism 6, thimble 7, top board 8, mould pin 9, base plate 10.

Described panel 1, cover half fixed head 2, dynamic mould fixing plate 4 are superimposed together successively, front cavity 3 as a die cavity part is arranged in cover half fixed head 2, rear cavity 5 as a die cavity part is arranged in dynamic mould fixing plate 4 and rear cavity 5 is relative with front cavity 3, thimble 7 activity is located in dynamic mould fixing plate 4 and rear cavity 5, die cavity is stretched in one end of thimble 7, the other end of thimble 7 is fixed on top board 8, top board 8 is arranged between dynamic mould fixing plate 4 and base plate 10, and dynamic mould fixing plate 4 is connected by mould pin 9 with base plate 10.

Shown in composition graphs 2, described core-pulling mechanism 6 comprises oil cylinder 61 of loosing core, connector 62, self-locking block 63, front mold slide 64.The cylinder body of described oil cylinder 61 of loosing core is fixed on the sidewall of cover half fixed head 2; the piston rod of oil cylinder 61 of loosing core stretches into cover half fixed head 2; the piston rod of oil cylinder 61 of loosing core is connected with connector 62 one end of slipping in cover half fixed head 2; connector 62 other end is provided with slide rail 621 and is fixed with self-locking block 63; the chute 641 of front mold slide 64 one end to slip on the slide rail 621 of connector 62 and the draw-in groove 642 of this end of front mold slide 64 and self-locking block 63 holding, and front mold slide 64 other end stretches into die cavity.

Operation principle of the present utility model:

1, as shown in Figure 3, the piston rod of oil cylinder 61 that core-pulling mechanism 6 is loosed core shrinks, and drive self-locking block 63 departs from the draw-in groove 642 on front mold slide 64; as shown in Figure 4; meanwhile, the slide rail 621(on connector 62 is as shown in Figure 2) drive front mold slide 64 to depart from die cavity by chute 641, complete and loose core.

2, as shown in Figure 5, die sinking, cover half fixed head 2 is separated with dynamic mould fixing plate 4.
