Description

  The present invention relates to a plastic molding apparatus, and more particularly to a one-step injection-drawing blown plastic bottle machine.

  Conventional PET (thermoplastic polyester) one-step injection draw blowers can only mold 4 bottles at a time for 5 liter bottles. In the conventional model, since bottle manufacturing processes are all arranged in a line, when four 5 liter bottles are arranged in a line, it is sufficiently long and the length cannot be increased further. . This is because as the number of bottles increases, the width of the equipment increases, and the manufacturing cost and installation area of the apparatus also increase. The most important cause is that it is too far from the mold of the bottle material, and the intimateness injected from the screw causes insufficient injection into the mold of the bottle material, resulting in a rejected product.

  An object of the present invention is to provide a one-step injection / pull-out plastic bottle machine capable of forming eight bottles at a time for a 5-liter PET bottle, which is highly efficient, energy-saving and practical.

  In order to solve the above-described problems, a one-step injection-drawing blown plastic bottle machine of the present invention includes a machine base, an injection module for molding a work-in-process bottle material mounted on the machine base, and a work-in-process. A drawing blow module for forming a finished bottle from the bottle material and a moving template assembly. The injection module includes an injection head device and an injection fastening module provided together with the injection head device. The drawing blow module includes a drawing module and a blow molding fastening mechanism assembly provided together with the drawing module. The moving template assembly includes a moving template and a power mechanism connected to the moving template. The moving template is provided at the lower part of the injection fastening module and the drawing module and at the upper part of the blow molding fastening mechanism assembly, and rotates by driving a hydraulic motor as a power mechanism. A set of bottle material molds is left at the bottom of the injection fastening module, and the bottle material molds are used to form a bottle material mold arranged by a two-row sample arrangement method and a screw bottle opening part. It consists of a tooth plate. The upper part of the bottle material mold and the tooth plate are fixed to the lower surface of the moving template assembly, and a set of drawing blow molds arranged by the two-row sample arrangement method is accommodated in the blow molding fastening mechanism assembly. In the injection module, a bottle material of work in progress is injection-molded in a bottle material mold. The moving template is rotated by driving the power mechanism so that the bottle material of the work in progress enters the drawing blow mold, and is drawn and blow-molded into the finished product bottle by the drawing blow module.

  As described above, the one-step injection / pull-out plastic bottle machine of the present invention can be circulated and manufactured as a single machine, and can be molded into 8 bottles of 5 liters at a time, thereby increasing the production efficiency of PET bottles.

The drawing air cylinder 41 is inserted with a drawing rod corresponding thereto, blown after the bottle material is drawn vertically, blown to the shape required by the mold, cooled, and then supplied from the rear end of the mold opening / closing oil cylinder 53. . After mold opening, air is supplied from the upper end of the separation tooth release air cylinder 46 and descends to open the two molded plates of the tooth plate 71. After the molded bottle body has fallen, it is refueled from the lower part of the moving frame oil cylinder 48 to raise the extraction frame 43, and the sealing air cylinder 44 and the extraction air cylinder 41 are simultaneously raised and reset for the next circulation. I will wait.

After the other one-round bottle material is formed, the power mechanism 65, which is a servo motor or a hydraulic motor, is reversed, and the moving template assembly 6 is rotated 180 degrees to the drawing / blowing operation position, and the forward / reverse circulation is repeated. Perform the action. That is, the bottle material is molded, and the other operation positions are also subjected to the drawing and blowing process to mold the finished product bottle.
(Second Embodiment)
As shown in FIG. 3, in the second embodiment of the present invention, the blow molding fastening mechanism assembly 5 includes a mold opening / closing oil cylinder 53 ′, and the mold opening / closing oil cylinder 53 ′ is blow molding. In the fastening mechanism assembly 5, it is located in the middle of the lower part.

(Third embodiment)
As shown in FIG. 4, the third embodiment of the present invention is different from the first embodiment in that the blow molding fastening mechanism assembly 5 includes two mold opening / closing oil cylinders 53 ″. The oil cylinder 53 ″ is positioned in the vicinity of the lower portions on both the left and right sides inside the blow molding fastening mechanism assembly 5.
In summary, the one-step injection / pull-out plastic bottle machine according to the present invention has a bottle material mold arranged by a two-row sample arrangement method, and the upper part of the bottle material mold and the tooth plate are the lower surfaces of the moving template assembly. The injection module includes an injection head device and an injection fastening module, and injection-molds the work-in-process bottle material. Furthermore, the work-in-process bottle material is rotated and moved to the drawing blow module by moving template assembly. The drawing blow module includes a drawing air cylinder and a corresponding drawing rod, is provided on a side surface of the injection fastening module, and is located at an upper part of the moving template assembly and is movable up and down. The blow molding clamping mechanism assembly completes the mold opening / closing operation by controlling the mold opening / closing oil cylinder. In this way, by displacing the drawing module and blow molding fastening mechanism assembly up and down, both molds are blown together, and the in-process bottle material arranged by the two-row sample arrangement method is drawn into the finished bottle. Blow molding. Thereby, the purpose of molding eight 5-liter PET bottles at a time can be achieved, and the production efficiency is remarkably increased. Next, manufacturing needs can be satisfied by selecting the mold opening and closing oil cylinders left in different positions based on the molds of the bottle material according to various different requirements. Moreover, if the drawing blow is not selected after the bottle material is molded, the bottle material becomes a work-in-process bottle material, but the bottle material can also be manufactured independently.
