Abstract
The invention relates to an easy-to-replace oblique pin device. The easy-to-replace oblique pin device comprises an oblique pin body, an oblique pin pull rod and a reset pin, wherein the oblique pin body is arranged in a male die core in an oblique mode, and the heads of the oblique pin pull rod and the reset pin sequentially penetrate through an upper ejector plate, a supporting plate and a male die plate; a T-shaped groove is designed in the lower end of the oblique pin body; a long strip boss arranged in the T-shaped groove is arranged at the head of the oblique pin pull rod; a threaded hole is designed in the head of the reset pin, and tails, with sectorial bosses, of the oblique pin pull rod and the reset pin are arranged in the upper ejector plate respectively; a reset spring is arranged between the upper ejector plate and the supporting plate on the reset pin in a sleeve mode. According to the easy-to-replace oblique pin device, rapid assembly and disassembly of an oblique pin can be achieved by 90-degree rotation of the oblique pin pull rod in the oblique pin body. Therefore, the die assembly-disassembly period is shortened, the workload of a bench worker is reduced, and the production efficiency is increased.
Description
Technical field
The present invention relates to mechanical-moulded field, refer in particular to one and easily change formula taper pin device.
Background technology
During injection moulding, when inner sides different from folding mould direction on plastic or outside have hole, depression or boss time, on mould, the part of this feature shaping must be designed to the slide block mechanism that can be displaced sideways or Slanting pin mechanism; In Slanting pin mechanism, common form has taper pin A seating taper pin and mother plate inclined pin etc., wherein key seat formula taper pin stable movement, but is fixed on upper ejector plate due to oblique pin base, and oblique pin base accounts for liftout plate space, and the occasion more for taper pin in mould is not too applicable; Generally mother plate inclined pin is adopted when there is overhead kick plastic master mold side and not easily adopts during slide block, but when adopting mother plate inclined pin, generally to increase shutter or the large structure such as pull bar, lower link bar, during to ensure die sinking, master mold seat board first separates with caster, then feature die separates again, cause the corresponding complexity of mould structure, for this reason, we have developed a kind of formula of easily changing taper pin device, by the 90-degree rotation of taper pin pull bar in taper pin body, quick-detachment and the assembling of taper pin can be realized, thus shorten the mold attaching/detaching cycle, reduce bench work amount, improve production efficiency.
Summary of the invention
The present invention seeks to provide one easily to change formula taper pin device to overcome the deficiencies in the prior art, by the 90-degree rotation of taper pin pull bar in taper pin body, quick-detachment and the assembling of taper pin can be realized, thus shorten the mold attaching/detaching cycle, reduce bench work amount, improve production efficiency.
For achieving the above object, the technical solution used in the present invention is: one easily changes formula taper pin device, comprises the taper pin body be inclined in male die core, head all successively through taper pin pull bar and the return pin of upper ejector plate, gripper shoe, male template; The lower end of described taper pin body is provided with T-slot; The head of described taper pin pull bar is provided with the rectangular boss be arranged in T-slot, by 90-degree rotation in T-slot, can connect fast with taper pin body and be separated; The head of described return pin is provided with screwed hole, and the afterbody that described taper pin pull bar and return pin are provided with fan-shaped boss is separately positioned in upper ejector plate; Described return pin is arranged with back-moving spring between upper ejector plate and gripper shoe.
Preferably, described upper ejector plate is provided with between upper ejector plate and gripper shoe the locating piece that at least 2 block gaps are placed.
Preferably, described locating piece is fixed by screws on upper ejector plate.
Preferably, on described taper pin body, the side adjacent with forming surface is provided with gib block.
Preferably, the two ends of described rectangular boss are circular arc.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The formula taper pin device that easily changes of the present invention, by the 90-degree rotation of taper pin pull bar in taper pin body, can realize quick-detachment and the assembling of taper pin, thus shorten the mold attaching/detaching cycle, reduce bench work amount, improve production efficiency.
