Detailed Description
The technical scheme of the high-precision four-guide-post die set according to the present invention will be further described in detail with reference to the following embodiments.
As shown in fig. 1-2, the high-precision four-guide-post die set comprises a base 1, an upper die 2, a lower die 3, a pair of moving mechanisms, a first screw rod 4, a second screw rod 5, a third screw rod 6 and a fourth screw rod 7, wherein two ends of one of the moving mechanisms are respectively screwed on the first screw rod 4 and the second screw rod 5, two ends of the other moving mechanism are respectively screwed on the first screw rod 4 and the second screw rod 5, and the pair of moving mechanisms can move oppositely on a vertical plane; the third screw rod 6 and the fourth screw rod 7 are respectively connected with a telescopic mechanism in a threaded manner, a through hole 8 is formed in the telescopic end of the telescopic mechanism, first protrusions 9 are arranged on two side faces of the upper die 2, second protrusions 10 are arranged on two side faces of the lower die 3, and after the upper die 2 and the lower die 3 are assembled, the first protrusions 9 and the second protrusions 10 are combined into a protrusion which can be inserted into the through hole 8 for fixing.
During operation, rotate first lead screw 4 and second lead screw 5, make this pair of moving mechanism remove in opposite directions, thereby make last mould 2 and the compound die of bed die 3 on the moving mechanism, first arch 9 and the protruding 10 formation of second are protruding, rotate third lead screw 6 and fourth lead screw 7, make telescopic machanism reach suitable height, start telescopic machanism, telescopic machanism flexible end stretches out and draws back forward, make the arch can insert in the through-hole 8, reach the effect of fixed compound die back mould, prevent that the mould from taking place the deviation, and increased the stability of mould at the in-process of moulding plastics.
In this embodiment, the moving mechanism includes a first moving bar 11, a second moving bar 12, and a nut 13; two ends of the first moving rod 11 and the second moving rod 12 are respectively fixedly connected with a nut 13, the first moving rod 11 is connected with the upper die 2, and the second moving rod 12 is connected with the lower die 3; first movable rod 11 can dismantle with last mould 2 and be connected, second movable rod 12 can dismantle with bed die 3 and be connected.
Because the first movable rod is detachably connected with the upper die, and the second movable rod is detachably connected with the lower die, the dies in various shapes can be switched at will, and the die switching device is convenient and quick.
