The specific embodiment

As shown in Figure 1; The utility model four station injection moulding machines comprise cope match-plate pattern 7, lower bolster 5, rotating disk 10, base plate 14, and cope match-plate pattern 7, lower bolster 5, base plate 14 are arranged at respectively on the guide pillar 13; Cope match-plate pattern 7 is arranged at the top of lower bolster 5, and the below of lower bolster 5 is provided with base plate 14;

The bottom of cope match-plate pattern 7 is provided with rotating mechanism 8, and the output of rotating mechanism 8 connects rotating disk 10, and rotating mechanism 8 is realized rotatablely moving of rotating disk 10 through driven by servomotor; Rotating disk 10 connects elevating mechanism through turntable mounting 6, realizes the elevating movement of rotating disk 10;

As shown in Figure 2, rotating disk 10 is provided with blow molding station 31, the station 32 of heating, injection moulding station 33, move back 34, four stations in die worker position and evenly distribute along the circumferencial direction of rotating disk 10;

Rotating disk 10 is equiped with four patrixes 11 successively on the relevant position of four stations, the position of corresponding four patrixes 11 is provided with four rotating disk circulation positioners 9 on the rotating disk 10; On the lower bolster 5 corresponding to being set with four counterdies 12 on the relevant position of four stations successively;

Elevating mechanism can drive rotating disk l0 and four patrixes 11 are done elevating movement, thereby accomplishes the action of folding mould;

Blow molding station 31 comprises metering motor 1, injection cylinder 2, seat oil-feed cylinder 3, injection screw 4, and blow molding station 31 is used to make-up machine the colloidal sol raw material is provided.

The operation principle of the utility model is following:

Lower bolster 5 and counterdie 12 are fixed; Elevating mechanism drives rotating disk 10 and moves up, and realizes the die sinking action; When rotating disk 10 moved to certain position and needs matched moulds, elevating mechanism promoted rotating disk 10 and moves downward, and rotating disk 10 drives patrixes 11 and moves downward together, when patrix 11 is run into counterdie 12, realizes locking, thereby realizes the locked mode action.

First patrix 11 is corresponding with first counterdie 12 on injection moulding station 33, realizes injection moulding bottle embryo; After injection moulding is accomplished; Elevating mechanism drive patrix 11 moves upward and accomplishes the die sinking action, and rotating mechanism 8 drive rotating disk l0 revolve and turn 90 degrees (clockwise), and it is corresponding with second counterdie 12 that first patrix 11 is gone to; The bottle embryo arrives the station 32 of heating, and realizes the location through rotating disk circulation positioner 9; Elevating mechanism drives patrix 11 and moves downward the action of completion locked mode;

On the station 32 of heating, realize heating; After heating is accomplished; Elevating mechanism drive patrix 11 moves upward and accomplishes the die sinking action; Rotating mechanism 8 drive rotating disk l0 equidirectional (clockwise) revolve and turn 90 degrees; It is corresponding with the 3rd counterdie 12 that first patrix 11 is gone to, and the bottle embryo arrives blow molding station 31, realizes the location through rotating disk circulation positioner 9; Elevating mechanism drives patrix 11 and moves downward the action of completion locked mode;

On blow molding station 31, bottle embryo stretching pressure-air is blown in bottle embryo, realizes the blow molding operation, form required container shapes; After the blow molding operation is accomplished; Elevating mechanism drive patrix 11 moves upward and accomplishes the die sinking action; Rotating mechanism 8 drive rotating disk l0 equidirectional (clockwise) revolve and turn 90 degrees; It is corresponding with the 4th counterdie 12 that first patrix 11 is gone to, and product arrives and moves back die worker position 34, realizes the location through rotating disk circulation positioner 9;

Product stripping is taken out moving back on the die worker position 34; Take out after the product; Elevating mechanism drive patrix 11 moves upward and accomplishes the die sinking action; Rotating mechanism 8 drive rotating disk l0 equidirectional (clockwise) revolve and turn 90 degrees, and it is corresponding with first counterdie 12 that first patrix 11 is gone to, and gets back to injection moulding station 33; Realize the location through rotating disk circulation positioner 9, can carry out another time injection molding process.

The utility model makes plastic melt get into injection moulding station 33 through injection screw and carries out injection moulding in product product process, through the heating of the station 32 of heating, again through the blow molding of blow molding station 31, product is taken out moving back on the die worker position 34 at last.Because when mould the inside moulding (like plastic bottle), the thickness of each surperficial plastics of bottle is to be difficult to control, behind first injection mould of experience after the plastic melt; Rotating disk 10 is to rising, and rotating disk 10 rotates when moving on to blow molding die again, and middle process is because of variation of temperature; The bottle base that thickness before differs has certain typing; After blowing, the thickness of the plastic housing of producing by boasting is conspicuous again, and the defect rate of product is very good.

The utility model is provided with the station 32 of heating between injection moulding station 33 and blow molding station 31; Rotating disk 10 revolutions angle once is 90 degree, and four patrix 11 corresponding four counterdies 12 are like this after this mould heating; The thickness that can solve product differs, and the finished product rate of coming out at last is high.
