Abstract
The invention relates to a plastic processing mold and discloses a plastic pouring core-pulling mold. The plastic pouring core-pulling mold comprises a fixed mold body and a movable mold body. The fixed mold body and the movable mold body are buckled to form a closed mold cavity. A core-pulling seat is further arranged between the fixed mold body and the movable mold body and clamped between the movable mold body and the fixed mold body. A boss for manufacturing a blind hole in a workpiece is arranged on the core-pulling seat and stretches into the mold cavity. The fixed mold body is provided with an oblique rod and a wedge block. The oblique rod penetrates the core-pulling seat. The wedge block is located at the end, away from the mold cavity, of the core-pulling seat and abuts against and makes contact with the end, and a wedge surface matched with the wedge block is arranged at the lower end of the core-pulling seat. A compression spring is arranged between the core-pulling seat and the fixed mold body. According to the scheme, through the structure, demolding and core pulling are completed at the same time, and the same power source (namely, demolding power for the movable mold body and the fixed mold body) is utilized; and the structure is simplified, no core-pulling operation needs to be independently conducted, and the demolding and core-pulling process is convenient and easy.
Description
Technical field
The present invention relates to a kind of plastic machining mold.
Background technology
Injection moulding is a kind of method of industrial products production moulding.Product uses rubber injection mold and plastics injection moulding usually.Injection moulding also can divide injection mould platen press and casting die.Injection (mo(u)lding) machine (being called for short injector or injection machine) utilizes mould for plastics to make the main former of the plastic products of various shape thermoplastic or thermosetting material, and injection moulding is realized by injection machine and mould.Product is widely used in: the industry such as mobile phone, laptop computer, multiple plastic shell, communication, micro machine, computer, electrical equipment, electronics, toy, clock and watch, lamp decoration, locomotive.Injection mold is the instrument producing plasthetics, is also the instrument giving plasthetics complete structure and accurate dimension.A kind of processing method used when injection mo(u)lding is some complex-shaped parts of batch production, specifically refers to the material melted that is heated to inject die cavity by high pressure, after cooling curing, obtains formed products.
Along with the day by day maturation of injection molding technology, increasing plastic cement products can be produced by injection moulding, simultaneously also more and more higher to the requirement of mould, at present for when there is poroid work pieces process, mostly be adopt operation of loosing core, extend in die cavity by plug, plug is extracted out after the plastic rubber shaping in die cavity, namely the workpiece with hole is obtained, but on original mould, add plug, can cause arranging core-pulling device in addition, thus also need to be equipped with other power source, this a series of device space hold that combines is high, and complex operation.
Summary of the invention
The invention is intended to provide a kind of structure simple, easy to operate plastic cement cast core-pulling die.
A kind of plastic cement cast core-pulling die in this programme, comprise fixed half and moving half, fixed half and moving half is interlocked and forms closed die cavity, also seat of loosing core is provided with between described fixed half and moving half, seat of loosing core is sandwiched between dynamic model and cover half, seat of loosing core is provided with the boss for making the blind hole on workpiece, and this boss extends in die cavity; Described cover half is provided with brace and wedge, and this brace runs through seat of loosing core, and wedge is positioned at seat of loosing core and contacts away from one end to offset with seat of loosing core of die cavity, and the lower end of seat of loosing core is the lozenges adapted with wedge, looses core between seat and cover half and is provided with stage clip.
Beneficial effect: dynamic model and cover half fit, make cavity closed, cast fused solution is deposited in curing molding in die cavity, then dynamic model and cover half are separated, when the relative cover half of dynamic model is moved apart, die cavity is while opening, seat of loosing core flicks under the elastic force of stage clip, seat of loosing core moves to the direction of dynamic model movement, loose core in seat and be also combined with the brace be fixed on cover half and the wedge being engaged in an end of loosing core, seat of loosing core is sandwiched between wedge and brace, the seat that causes loosing core can only move along the incline direction of brace, so die cavity is while opening, seat of loosing core also is doing oblique movement, the projection of loosing core on seat is caused to be extracted out from workpiece.The program by said structure, makes the demoulding and looses core to complete simultaneously, and make use of the same power source (i.e. the mould opening force of dynamic model and the cover half demoulding), simplify the structure, also need not carry out operation of loosing core separately, makes demoulding process of loosing core convenient and simple.
Further, also comprise cover half seat and dynamic model seat, described cover half is arranged on cover half seat, and dynamic model is arranged on dynamic model seat, is connect between cover half seat and dynamic model seat by cylinders.By air cylinder driven, be device automation more, save manpower, the setting party of dynamic model seat the installation of cylinder.
Further, on described dynamic model seat, the end of opposite wedge block is provided with cushion, and when avoiding dynamic model and cover half to close, wedge collides dynamic model inwall, slows down closure pressing speed simultaneously, increases the stability of mechanism.
Further, described dynamic model is provided with push rod, and this push rod extends to die cavity through dynamic model seat and dynamic model, promotes push rod, the workpiece be bonded on dynamic model can be released, laborsaving.
Further, the end of described push rod is provided with handle, facilitates holding of push rod.
Accompanying drawing explanation
Fig. 1 is the structural representation of plastic cement of the present invention cast core-pulling die embodiment.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: cover half 1, stage clip 11, brace 12, wedge 13, dynamic model 2, cushion 21, seat 3 of loosing core, boss 31, push rod 4.
Embodiment is substantially as shown in Figure 1:
Plastic cement cast core-pulling die in this programme, comprise cover half 1 and dynamic model 2, cover half 1 and dynamic model 2 are interlocked and form closed die cavity, seat 3 of loosing core also has been clamped between cover half 1 and dynamic model 2, seat 3 of loosing core is sandwiched between dynamic model 2 and cover half 1, loose core seat 3 upper end for making the boss 31 of the blind hole on workpiece, and this boss 31 extends in die cavity.
Cover half 1 is welded with brace 12 and wedge 13 from top to bottom, this brace 12 is through seat 3 of loosing core, wedge 13 is positioned at seat 3 of loosing core away from one end of die cavity and the contact that offsets, the loose core lower end of seat 3 is the lozenges adapted with wedge 13, this stage clip 11 is connected with screw, screw is screwed into looses core on seat 3, and welds with stage clip 11, and stage clip 11 other end is connected on cover half 1.
Cover half 1 is arranged on cover half 1, and dynamic model 2 is arranged on dynamic model 2, is connect between cover half 1 and dynamic model 2 by cylinders.By air cylinder driven, be device automation more, save manpower, the setting party that dynamic model is 2 the installation of cylinder.The end of the upper opposite wedge block 13 of dynamic model 2 is provided with cushion 21, and lid cushion 21 adopts sponge to make, and when avoiding dynamic model 2 and cover half 1 to close, wedge 13 collides dynamic model 2 inwall, slows down closure pressing speed simultaneously, increases the stability of mechanism.
