Abstract
The utility model relates to a kind of screw thread core pulling spline location structure, mainly comprises oil motor, rotating missile block and rotating core; The driving shaft of described oil motor is fixed with the first pinion, be engaged mutually by chain between this first pinion with second pinion, the second described pinion is engaged mutually with the first gear be symmetric, second largest gear, this first gear, second largest gear are individually fixed on two rotating cores, what contact respectively with these two rotating cores has rotating missile block, and these two pieces of rotating missile blocks are diagonal angle distribution; Described rotating missile block is limited on mould by alignment pin, is provided with spring between this rotating missile block and spring anchor block; Described rotating core is provided with right angle draw-in groove, this right angle draw-in groove pushes up with rotating missile block mutually when rotating core turns clockwise; The beneficial effects of the utility model are: by this structure, and shortening injection molding cycle 35%, that product screw thread plays tooth positional stability is high.
Description
Technical field
The utility model belongs to location structure technical field, particularly relates to a kind of screw thread core pulling spline location structure.
Background technology
The position that existing product screw thread tooth position is located through tooth bar controls, during mould matched moulds oil cylinder 12 left work strip carry-over bar 13 move to diagram 1 position, the occlusion of this hour rack 13 secures core gear 14, the tooth position of rising of product screw thread has uniqueness, plastics mould filling enter the die sinking of die cavity rear mold put in place after oil cylinder 12 move right band carry-over bar 13 move to diagram 2 position, tooth bar 13 motion rotating core gear 14 product stripping completes, product injection cycle completes, mould again mold-closing injection carries out next one circulation, such screw thread plays tooth position and is engaged fixed core gear 14 as diagram 1 position by oil cylinder 12 tooth bar 13 during mould matched moulds, product screw thread plays tooth and has uniqueness all the time, but its cycle that there is injection moulding is long, the defect that stability is not high.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides the screw thread core pulling spline location structure that a kind of injection cycle is short, stability is high.
The purpose of this utility model has been come by following technical solution.This screw thread core pulling spline location structure, mainly comprises oil motor, rotating missile block and rotating core; The driving shaft of described oil motor is fixed with the first pinion, be engaged mutually by chain between this first pinion with second pinion, the second described pinion is engaged mutually with the first gear be symmetric, second largest gear, this first gear, second largest gear are individually fixed on two rotating cores, what contact respectively with these two rotating cores has rotating missile block, and these two pieces of rotating missile blocks are diagonal angle distribution.
As preferably, described rotating missile block is limited on mould by alignment pin, is provided with spring between this rotating missile block and spring anchor block.
As preferably, described rotating core is provided with right angle draw-in groove, this right angle draw-in groove pushes up with rotating missile block mutually when rotating core turns clockwise.
The beneficial effects of the utility model are: by this structure, product screw thread tooth position is located through oil motor and drives chain occlusion rotating core to withstand by the right angle draw-in groove of rotating core and rotating missile block to control screw thread and play tooth position, screw thread plays tooth position and has normal place uniqueness, thus shortening injection molding cycle 35%, that product screw thread plays tooth positional stability is high.

Detailed description of the invention
Do detailed introduction below in conjunction with accompanying drawing to the utility model: as shown in accompanying drawing 3,4, the utility model mainly comprises oil motor 1, rotating missile block 4 and rotating core 9; The driving shaft of described oil motor 1 is fixed with the first pinion 10, be engaged mutually by chain 2 between this first pinion 10 with the second pinion 7, the second described pinion 7 is engaged mutually with the first gear 8 be symmetric, second largest gear 11, this first gear 8, second largest gear 11 are individually fixed on two rotating cores 9, what contact respectively with these two rotating cores 9 has rotating missile block 4, the distribution in diagonal angle of these two pieces of rotating missile blocks 4; Described rotating missile block 4 is limited on mould by alignment pin 5, is provided with spring 6 between this rotating missile block 4 and spring anchor block 3.
As shown in Figure 5, described rotating core 9 is provided with right angle draw-in groove 91, this right angle draw-in groove 91 when rotating core turns clockwise with rotating missile block 4 phase top.
Operation principle of the present utility model is: product screw thread tooth position is located through oil motor 1 and drives chain 2 to be engaged rotating core 9 to allow the right angle draw-in groove 91 of rotating core 9 and rotating missile block 4 withstand to control.During mould matched moulds, oil motor 1 is rotated counterclockwise driven rotary core 9 and turns clockwise, rotating missile block 4 under the effect of spring 6 power with the center of alignment pin 5 for the center of circle moves upward, when behind the A position moving to diagram 3, rotating missile block 4 withstands the right angle draw-in groove 91 of rotating core 9, now product screw thread plays the uniqueness that toilet article have standard; After after plastics mould filling enters die cavity, die sinking puts in place, oil motor 1 rotarily drives first gear 8, second largest gear 11 on the first pinion 10, second pinion 7 and rotating core 9, as diagram 4 product strippings after after rotating core 9 is counterclockwise, rotating missile block 4 moves downward 1.5 degree to B position, an injection cycle end cycle enters next and circulates.
The utility model is not limited to above-mentioned embodiment; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection domain.
