The movable blocks (1) and the bottom plate (2) are arranged between the upper mold (3) and the lower mold (4), the movable blocks (1) are radially and slidingly fitted in a radial slot (2.1) on the bottom plate (2), a synchronous movable block-drawing device is arranged in the bottom plate (2) and is respectively connected with the movable blocks (1), and an operating handle (5) is arranged on the synchronous movable block-drawing device. The mold-opening mechanism has high working efficiency and high accuracy.
Description
Technical field
The utility model relates to a kind of die opening mechanism, specifically is a kind of synchronous die opening mechanism of impeller class.
Background technology
The die opening mechanism of prior art comprises patrix, a plurality of loose piece, base plate and counterdie, and described a plurality of loose pieces and base plate are located between the upper die and lower die; Described a plurality of loose piece surrounds a week, forms the mould of an impeller class; Described a plurality of loose piece is radially in the groove of sliding fit on base plate.There is following defective in the die opening mechanism of above-mentioned this structure:
1, above-mentioned die opening mechanism is to be made of a plurality of loose pieces, and the manual mode multidirectional, pull loose piece one by one of many at work employings is carried out die sinking, so the efficient of above-mentioned die opening mechanism is lower.
2, because above-mentioned a plurality of loose pieces all are to put in place by manual pull, the problem that differs in this a plurality of loose pieces position that just will inevitably cause being caused in the manual pull, the ratio of precision of the die opening mechanism of said said structure is lower, thus the defect rate of producing product is than higher.
In sum, the die opening mechanism of prior art exists inefficiency and the low defective of precision.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of high efficiency and precision high synchronous die opening mechanism.
The technical solution of the utility model is, a kind of synchronous die opening mechanism is provided, and comprises a plurality of loose pieces, base plate, upper die and lower die, and described a plurality of loose pieces and base plate are located between the upper die and lower die; Described a plurality of loose piece is radially in the radial slot of sliding fit on base plate; Be provided with a synchronous loose piece in the described base plate and twitch device, described synchronous loose piece is twitched device and all is connected with a plurality of loose pieces; Described synchronous loose piece is twitched device and is provided with an operating grip.
After adopting above structure, the utility model compared with prior art has the following advantages:
1, the synchronous die opening mechanism of the utility model is provided with a synchronous loose piece and twitches device, only used needs directly axially pull operating grip a plurality of loose pieces are operated simultaneously, so operating efficiency of the present utility model is than higher.
2, owing to be to operate by operating grip, so the problem that does not exist a plurality of loose pieces position to differ in operating process, therefore, the ratio of precision of the synchronous die opening mechanism of the utility model is higher, and the defect rate of producing product is lower.
As improvement, the bottom of axle of the present utility model is provided with a rolling bearing, axle and being slidingly matched of arc groove is become roll to cooperate, thereby make the user more laborsaving when operation.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of synchronous die opening mechanism of the utility model comprises a plurality of loose pieces 1, base plate 2, patrix 3 and counterdie 4, and described a plurality of loose pieces 1 and base plate 2 are located between patrix 3 and the counterdie 4; Described radial slot 2.1 is made of two blocks of parallel-plates that are fixed on the base plate 2; Described a plurality of loose piece 1 is radially in the radial slot 2.1 of sliding fit on base plate 2; Be provided with a synchronous loose piece in the described base plate 2 and twitch device, described synchronous loose piece is twitched device and all is connected with a plurality of loose pieces 1; Described synchronous loose piece is twitched device and is provided with an operating grip 5.
The concrete structure of described synchronous twitch loose piece device is: comprise circular bottom plate 6 and axle 7, described operating grip 5 is located at the sidepiece of circular bottom plate 6; Described circular bottom plate 6 is located on the counterdie 4 and with counterdie 4 and is rotatably assorted; Described circular bottom plate 6 is provided with the arc groove 8 that equates with loose piece 1 quantity, and the minimum angle α of spot diameter is greater than 0 ° and less than 90 ° in described arc groove 8 corresponding strings and the described string of mistake; Described axle 7 is located between described loose piece 1 and the arc groove 8, and the top of described axle 7 is fixedly connected on the loose piece 1, and its bottom is inserted in arc groove 8.
The bottom of described axle 7 is provided with a rolling bearing 9, and the inner headed face of rolling bearing 9 is bonding with the periphery of axle 7, and described rolling bearing 9 rolls and is engaged in the arc groove 8.
Operation principle: pull operation 5 handles and rotate in a circumferential direction, axle 7 moves along arc groove 8, because the minimum angle α of spot diameter is greater than 0 ° and less than 90 ° in arc groove 8 corresponding strings and the described string of mistake, so can change the radial motion of loose piece 1 into by the axially-movable of operating grip 5, simultaneously owing to be to rotate together by whole circular bottom plate 6, move together so can drive a plurality of loose pieces 1, reach synchronous effect.
