Abstract

The invention discloses a kind of injection mold without twice-die-opening, including panel, cover half fixed plate, front cavity, dynamic mould fixing plate, rear cavity, thimble, top plate, support block, bottom plate, core-pulling mechanism.Described panel, cover half fixed plate, dynamic mould fixing plate are superimposed together successively, front cavity is arranged in cover half fixed plate, rear cavity 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 into one end of thimble, the other end of thimble is fixed on top plate, and top plate is arranged between dynamic mould fixing plate and bottom plate, and dynamic mould fixing plate is connected with bottom plate by support block.Core-pulling mechanism is arranged in cover half fixed plate.Because the present invention has the core-pulling mechanism being made up of parts such as core pulling oil cylinder, connector, self-locking block, front mold slides, before die sinking, front mold slide can be detached die cavity by core pulling oil cylinder; complete core pulling action; twice-die-opening action, formed product cycle time are saved, cost reduces.

Description

Injection mold without twice-die-opening
Technical field
The present invention relates to a kind of injection mold, more particularly to a kind of injection mold without twice-die-opening.
Background technology
The structure of plastic product on existing market becomes increasingly complex, and many plastic products all have inside groove, thus it requires Mould also has and can be molded the structure of this inside groove, this require with it is a kind of can be intact mould is taken out from inside groove The structure gone out, but this mould that can quickly and easily extract out has certain difficulty, and this respect is also always this area Technical staff's problem to be solved.Not Tongfang will be mostly in by the way of multiple die sinking, multiple core pulling in the prior art Core into groove is extracted out, with regard to the more of complexity so in technique and structure, is also unfavorable for producing in enormous quantities.
The content of the invention
It is an object of the invention to provide a kind of formed product cycle is short, reliable in action, simple in construction is opened without secondary The injection mold of mould.
To achieve the above object, technical solution of the invention is:
The present invention is a kind of injection mold without twice-die-opening, including panel, cover half fixed plate, front cavity, dynamic model are solid Fixed board, rear cavity, thimble, top plate, support block, bottom plate, core-pulling mechanism;Described panel, cover half fixed plate, dynamic mould fixing plate are successively It is superimposed together, the front cavity as a die cavity part is arranged in cover half fixed plate, the rear cavity peace as a die cavity part In dynamic mould fixing plate and rear cavity is relative with front cavity, and thimble activity is located in dynamic mould fixing plate and rear cavity, thimble One end stretch into die cavity, the other end of thimble is fixed on top plate, and top plate is arranged between dynamic mould fixing plate and bottom plate, and dynamic model is solid Fixed board is connected with bottom plate by support block;
Described core-pulling mechanism includes core pulling oil cylinder, connector, self-locking block, front mold slide;The cylinder of described core pulling oil cylinder Body is fixed in the side wall of cover half fixed plate, and the piston rod of core pulling oil cylinder stretches into cover half fixed plate, the piston rod of core pulling oil cylinder with Connector one end connection in cover half fixed plate is slipped, the connector other end is provided with slide rail and is fixed with self-locking block, and preceding mould is slided The chute of block one end is slipped on the slide rail of connector and the neck at the front mold slide end and self-locking block holding, front mold slide are another Die cavity is stretched at end.
After such scheme, because the present invention has by parts such as core pulling oil cylinder, connector, self-locking block, front mold slides The core-pulling mechanism of composition, before die sinking, core pulling oil cylinder can detach front mold slide die cavity, complete core pulling action, save secondary Die sinking acts, and formed product cycle time, reduces cost.In addition, the present invention is provided with sliding block self-locking mechanism(Self-locking block), avoid Because formed product is bad caused by briquetting pressure retreats sliding block the defects of so that present invention action is relatively reliable.With reference to The present invention is further illustrated for the drawings and specific embodiments.

Embodiment
As shown in figure 1, the present invention is a kind of injection mold without twice-die-opening, including it is panel 1, cover half fixed plate 2, preceding Die 3, dynamic mould fixing plate 4, rear cavity 5, core-pulling mechanism 6, thimble 7, top plate 8, support block 9, bottom plate 10.
Described panel 1, cover half fixed plate 2, dynamic mould fixing plate 4 are superimposed together successively, before a die cavity part Die 3 is arranged in cover half fixed plate 2, and the rear cavity 5 as a die cavity part is arranged in dynamic mould fixing plate 4 and rear cavity 5 Relative with front cavity 3, the activity of thimble 7 is located in dynamic mould fixing plate 4 and rear cavity 5, and die cavity, thimble 7 are stretched into one end of thimble 7 The other end be fixed on top plate 8, top plate 8 is arranged between dynamic mould fixing plate 4 and bottom plate 10, dynamic mould fixing plate 4 and bottom plate 10 Connected by support block 9.
With reference to shown in Fig. 2, described core-pulling mechanism 6 includes core pulling oil cylinder 61, connector 62, self-locking block 63, front mold slide 64.The cylinder body of described core pulling oil cylinder 61 is fixed in the side wall of cover half fixed plate 2, and the piston rod of core pulling oil cylinder 61 stretches into cover half Fixed plate 2, the piston rod of core pulling oil cylinder 61 are connected with the one end of connector 62 slipped in cover half fixed plate 2, and connector 62 is another One end is provided with slide rail 621 and is fixed with self-locking block 63, and the chute 641 of the one end of front mold slide 64 slips the slide rail in connector 62 On 621 and the neck 642 at the end of front mold slide 64 and the holding of self-locking block 63, the other end of front mold slide 64 stretch into die cavity.
The operation principle of the present invention:
1st, as shown in figure 3, the piston rod of core pulling oil cylinder 61 shrinks on core-pulling mechanism 6, drive self-locking block 63 to depart from preceding mould and slide Neck 642 on block 64, as shown in figure 4, simultaneously, the slide rail 621 on connector 62(As shown in Figure 2)Driven by chute 641 Front mold slide 64 departs from die cavity, completes core pulling.
