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 obtain the workpiece with hole, but add plug on original mould, be mostly to take extraction action, during owing to manually extracting out, speed is difficult to control, or causes plug to offset, and just shaping workpiece is very easily out of shape and even damages.
Summary of the invention
The invention is intended to provide one to loose core stable, avoid the plastic cement of defective work piece to pour into a mould screw rod and to loose core mould.
Plastic cement cast screw rod in this programme is loosed core mould, 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 seat of loosing core is connected with screw rod away from one end of die cavity, seat of loosing core is provided with circular groove, bolt on seat of loosing core is connected with the cover plate blocked by circular groove, this cover plate has the through hole that bore is less than circular groove diameter, the end of screw rod is provided with the round platform with circular groove matched in clearance, the end of screw rod is through the through hole on cover plate and round platform is sandwiched in circular groove and cover plate, and screw rod can rotate relative to seat of loosing core, and screw flight is connected to is located at stretching out on step on cover half.
Beneficial effect: dynamic model and cover half fit, rotary screw, screw rod does axial screw, and because the end of screw rod and the circular groove of loosing core on seat are matched in clearance, screw rod rotates relative to seat of loosing core, and promotion is loosed core, seat is that boss inserts die cavity, make die cavity seal for cast, cast fused solution is deposited in die cavity after curing molding, contra rotating screw, pull seat of loosing core to move away from die cavity, boss is extracted die cavity and is completed action of loosing core; When boss shifts out die cavity completely, separated by fixed half and moving half, workpiece exposes, and takes off workpiece.Adopt the program, carry out loosing core action by the cooperation of gear and tooth bar, extraction action is compared in the operation that gear rotates, and controllability is stronger, so ensure that the stable of the process of loosing core, avoids occurring workpiece deformation or damaged condition.
Further, also comprise cover half seat and dynamic model seat, described cover half is arranged on cover half seat, dynamic model is arranged on dynamic model seat, is connect, pass through air cylinder driven between cover half seat and dynamic model seat by cylinders, be device automation more, save manpower, the setting party of dynamic model seat the installation of cylinder.
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.
Further, described screw rod is provided with handwheel away from the one end of seat of loosing core, and handwheel facilitates artificial turn screw rod, laborsaving.
Accompanying drawing explanation
Fig. 1 is that plastic cement of the present invention cast screw rod is loosed core the structural representation of mould 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, dynamic model 2, seat 3 of loosing core, boss 31, cover plate 32, screw rod 4, handwheel 41, push rod 5.
Embodiment is substantially as shown in Figure 1:
Plastic cement cast screw rod in this programme is loosed core mould, 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, seat 3 upper end of loosing core is processed with boss 31 for making the blind hole on workpiece, and this boss 31 extends in die cavity;
Seat 3 of loosing core is connected with screw rod 4 away from one end of die cavity, seat 3 lower end of loosing core also has circular groove, this terminal bolt of seat 3 of loosing core is connected with the cover plate 32 blocked by circular groove, this cover plate 32 has the through hole that bore is less than circular groove diameter, the welding edges of screw rod 4 has the round platform with circular groove matched in clearance, the end of screw rod 4 is through the through hole on cover plate 32 and round platform is sandwiched in circular groove and cover plate 32, and screw rod 4 can rotate relative to seat 3 of loosing core, and screw rod 4 is threaded in is located at stretching out on step on cover half 1.
