specific Embodiment approach

[0010] First put the front cover 3 into the movable template 2, then put the front cylinder 4 into it, then the front cover 3 can be stuck, put the Gelin pillar, that is, the piston rod 5, and then install the front piston 6 on the Gelin Then install the middle cover 8 and the rear oil cylinder piston 10 in sequence, and finally screw on the nut 11 to lock the parts loaded in the front, and finally install the rear oil cylinder body 9 and the rear cover 12 with the pull rod 13 And the nut is fixed on the moving template.

[0011] During operation, one pressure oil enters the front chamber of the front cylinder through the oil port of the middle cover 8, and one road of hydraulic oil enters the front chamber of the rear cylinder through the other oil port of the middle cover 8, and the pressure oil passes through the piston 10, piston rod 5, The oil passage (1) of the front piston 6 reaches the front chamber of the front oil cylinder.

[0012] There are two functions of series...

Abstract

The invention discloses a serial adjusting film and locking film oil cylinder, which pertains to a hydraulic oil cylinder device and solves steel waste, large size of seals and high price caused by huge volume and large occupied area of the oil cylinders with relatively large pressure as well as the problem of inconvenient maintenance. The invention comprises a movable template (2), a prepositive oil cylinder and a postposing oil cylinder, wherein, a cylinder body (4) of the prepositive oil cylinder is fixedly arranged inside the movable template (2) and a piston bar (5) thereof extends out of the oil cylinder through a front cover (3) of the prepositive oil cylinder; however, the postposing oil cylinder is connected with the prepositive oil cylinder through a middle cover (8) in series; meanwhile, a piston bar of the postposing oil cylinder enters a rear cavity of the prepositive oil cylinder through the middle cover (8) and the head part thereof is fixedly connected with a piston (6) of the prepositive oil cylinder, an oil line (1) is arranged on the piston bar of the postposing oil cylinder, and a front cavity of the prepositive oil cylinder is communicated with a rear cavity of the postposing oil cylinder through the oil line. The invention is especially applicable for locking film mechanisms of large and super large injecting machines.

Description

Technical field: [0001] The invention relates to a hydraulic oil cylinder, in particular to a series-connected mold adjustment and clamping oil cylinder of a two-platen injection molding machine. Background technique [0002] At present, the main types of injection molding machines are toggle-link type, and there are very few two-platen injection molding machines; but in terms of overall superior performance, two-platen injection molding machines have become more and more popular, and will represent injection molding machines. direction of development. However, the output pressure of the hydraulic cylinder on the injection molding machine is directly proportional to the bore size of the cylinder body. A cylinder with a higher pressure will be bulky, occupy a large area and consume steel, inconvenient maintenance, short service life, and poor system rigidity. Contents of the invention [0003] The tandem mold adjustment and clamping oil cylinder provided by the invention o...
