Embodiment Construction

[0061] Hereinafter, embodiments of the present invention will be described based on the drawings. In addition, it is assumed that the drawings are viewed in the orientation of the reference numerals.

[0062] [Example]

[0063] Such as figure 1 As shown, the injection molding device 10 is composed of a machine platform 11 (the machine platform 11 is composed of legs 12 and an upper plate 13), a rotary table 14 rotatably arranged on the upper plate 13, and a rotating shaft of the rotary table 14 15 is the first mold clamping mechanism 20 and the second mold clamping mechanism 30 for clamping the molds 16 and 17 which are centrally arranged at symmetrical positions, and the first injection which is attached to the first mold clamping mechanism 20 and injects the resin material into the mold 16. The machine 40 and the second injection machine 55 attached to the second mold clamping mechanism 30 and injecting the resin material into the mold 17 are constituted.

Abstract

An injection molding apparatus includes, as its drive sources, an electric power supply source, compressed air source and hydraulic pressure supply source. A hydraulic-pressure-supply-destination selection section supplies hydraulic pressure from the hydraulic pressure supply source to a selected one of first and second mold clamping cylinders. Necessary capacity of the hydraulic pressure supply source can be lowered as compared to a case where all of the mold clamping mechanisms and injecting machines are driven by hydraulic pressure. Because only a selected one of the mold clamping mechanisms is driven at a time, the necessary capacity of the hydraulic pressure supply source can be halved as compared to a case where the mold clamping mechanisms are driven simultaneously.

Description

technical field [0001] The present invention relates to an injection molding apparatus provided with a plurality of mold clamping mechanisms. Background technique [0002] Many injection molding devices are composed of a mold clamping mechanism and an injection machine, and a resin material is injected into a mold closed by the mold clamping mechanism to obtain a molded product. However, there are limitations in terms of productivity. [0003] Therefore, an injection molding device composed of a plurality of clamping mechanisms and a plurality of injection machines has been proposed (for example, refer to Patent Document 1 ( figure 1 , figure 2 )). [0004] As in Patent Document 1 figure 1 and figure 2 As shown, the injection molding apparatus (M) (numbers in parentheses indicate reference numerals described in Patent Document 1, the same applies hereinafter) includes an injection machine (Mix), a mold clamping mechanism (Mcx), an injection machine (Miy), Clamping me...
