Description

One easily changes formula taper pin device
Technical field
The utility model relates to mechanical-moulded field, refers in particular to one and easily changes 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.
Utility model content
The utility model object provides 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 adopted in the utility model 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 utility model compared with prior art has following advantages:
The formula taper pin device that easily changes described in the utility model, 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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the sectional view easily changing formula taper pin device described in the utility model;
Accompanying drawing 2 is the schematic diagram easily changing taper pin body and taper pin pull bar in formula taper pin device described in the utility model;
Accompanying drawing 3 is the partial enlarged drawing easily changing taper pin rod head in formula taper pin device described in the utility model;
Wherein: 1, male template; 2, male die core; 3, plastic; 4, taper pin body; 41, T-slot; 42, gib block; 5, taper pin pull bar; 51, fan-shaped boss; 52, rectangular boss; 6, return pin; 61, screwed hole; 7, back-moving spring; 8, locating piece; 9, screw; 10, upper ejector plate; 11, gripper shoe; 12, lower liftout plate; 13, lower bolster.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1-3 described in the utility modelly easily changes formula taper pin device, comprises the taper pin body 4 be inclined in male die core 2, head all successively through taper pin pull bar 5 and the return pin 6 of upper ejector plate 10, gripper shoe 11, male template 1; Side adjacent with forming surface on described taper pin body 4 is provided with gib block 42, and taper pin body 4 can be moved along gib block 42 direction, and be convenient to and plastic 3 demoulding, lower end is provided with T-slot 41; The head of described taper pin pull bar 5 is provided with two ends and is circular arc and is arranged on the rectangular boss 52 in T-slot 41, by 90-degree rotation in T-slot 41, can connect fast with taper pin body 4 and be separated; The head of described return pin 6 is provided with screwed hole 61, taper pin pull bar 5 for convenience detach; The afterbody of described taper pin pull bar 5 and return pin 6 is respectively arranged with fan-shaped boss 51; Described fan-shaped boss 51 is arranged in upper ejector plate 10, prevents taper pin pull bar 5 and return pin 6 from rotating; Described return pin 6 is arranged with back-moving spring 7 between upper ejector plate 10 and gripper shoe 11; The upper surface of described upper ejector plate 10 is provided with the locating piece 8 that 2 block gaps are placed, prevents from making because ejection stroke is oversize taper pin body 4 depart from from male die core 2; Described locating piece 8 is fixed on upper ejector plate 10 by screw 9.
During dismounting taper pin: first the lower liftout plate 12 below the caster above male template 1, cope match-plate pattern and upper ejector plate 10, mould pin and lower bolster 13 are taken off; Be screwed into by special instrument again in the screwed hole 61 of return pin 6 head, the elastic force making return pin 6 overcome back-moving spring 7 drives upper ejector plate 10 to move upward, the fan-shaped boss 51 of taper pin pull bar 5 afterbody is exposed in upper ejector plate 10, now taper pin pull bar 5 90-degree rotation just can be departed from taper pin body 4, carry out changing or keeping in repair.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The formula taper pin device that easily changes described in the utility model, 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.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
