As a kind of improvement, described push-pull device at fixed is the leading screw that is provided with along the ram direction, is provided with contiguous block between leading screw and the dies holder.

As further improvement, described front template is provided with pull bar, template was connected with rear pattern plate during pull bar passed, front template is installed with hydraulic jack on the center, the output of hydraulic jack is connected with middle template, and being respectively equipped with on front template, middle template and the rear pattern plate can be along the wheel of sliding rail slip.

As further improvement, between the discharging opening of described machine barrel and the storage cavity of die head the transition backing plate is installed.

Owing to adopted technique scheme; described double full-automatic plastic hollow machine; by ram and push-pull device at fixed being installed in the dies holder bottom; dies holder can be moved around on ram, be about to that two cover clasp mould mechanisms take turns be positioned at die head under, make machine have two stations; saved the time; improve operating efficiency, because the realization of the control device of each system of machine is full-automatic, reduced working strength of workers simultaneously.

Description of drawings

Fig. 1 is the structural representation of a kind of embodiment of the utility model;

Fig. 2 is the left view of clasp mould mechanism among Fig. 1.

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.Double full-automatic plastic hollow machine comprises frame 1, is installed in the machine barrel 2 on the frame 1, and an end of machine barrel 2 is connected with decelerator 3, and decelerator 3 is connected with the material extrusion frequency control motor, thereby it can accurately control the rotating speed control material extrusion speed of screw rod 5.Machine barrel 2 is installed with hopper 4 near an end of decelerator 3, screw rod 5 is installed in the machine barrel 2, machine barrel 2 is connected with heater, heater can be heated to molten condition with the plastics in the machine barrel 2, raw material is passed through heating and pushes mixing, under the turning effort of screw rod 5, will be fed forward and compacting the final plasticizing material embryo uniformly that forms from the plastics that hopper 4 enters machine barrel 2.

Be fixedly mounted on the die head 6 on the frame 1, die head 6 is connected with cooling system, be provided with storage cavity and nozzle 61 in the die head 6, storing is arranged on the interior direct die head feed that is of runner of die head, storage cavity is communicated with the discharging opening of machine barrel 2, guarantee molten plastic when shooting material, the molten plastic that is introduced into storage cavity at first penetrates in die head.Between discharging opening and the storage cavity transition backing plate can be installed, perhaps make the transition backing plate into screen pack as required.The die head oral area is provided with radial clearance and adjusts bolt, to adjust the axiality of inside and outside die orifice, makes the radial thickness in type embryo cross section even.

The below of die head 6 is provided with clasp mould mechanism 7; clasp mould mechanism 7 comprises dies holder 71; be fixedly mounted on the polished rod 72 on the dies holder 71; also be provided with transversely movable rail plate 73 on the dies holder 71; front template 74 is installed on the rail plate 73; middle template 75 and rear pattern plate 76; four angles of described front template 74 are provided with pull bar 77; template 75 was connected with rear pattern plate 76 during pull bar 77 passed; front template is installed with hydraulic jack 78 on 74 centers; the output of hydraulic jack 78 is connected front template 74 with middle template 75; being respectively equipped with on middle template 75 and the rear pattern plate 76 can be along the wheel of sliding rail 73 slips.This mechanism is used for installation mold and allows mould have the parts of reliably closing, unlatching, must possess the smooth inflation that enough clamp forces guarantee goods, and clamp force derives from hydraulic jack.When the folding mould, speed-change process is arranged, be generally: slow and---soon---slowly, make the mould safe operation and improve the speed of folding mould.
