Abstract
The utility model provides a front end cover of a working cylinder for opening and closing a mould locking device of a plastic bottle blowing machine, which comprises a piston rod hole, an air inlet passage and an air outlet passage which are communicated with the piston rod hole and are arranged the lateral wall of the front end cover, and a one-way valve which is communicated with the air inlet passage and the air outlet passage and is arranged on the back wall of the front end cover. The utility model has simple structure. When a mould is closed, air can be smoothly exhausted by the air inlet passage and the air outlet passage which are communicated with the piston rod hole. When the mould is opened, compressed air simultaneously enters a cylinder body by the one-way valve and directly acts on a piston from the back wall of the front end cover, and the mould opening process is easy and fast. The one-way valve comprises an air inlet nozzle part which is arranged in the front end cover, and a valve seat which is communicated with the air inlet passage and the air outlet passage, wherein the valve seat is provided with a valve core which is matched with the air inlet nozzle part; an end head which is elastically connected with the valve core, is connected with the valve seat and is provided with a through hole is arranged on the back of the valve core.
Description
Technical field
The utility model relates to blower for plastic bottle opening-closing lock die device field, the particularly drive end bearing bracket of working cylinder wherein.
Background technology
At present, have in the blower for plastic bottle opening-closing lock die device with air pressure and combine the working cylinder that carries out die sinking, matched moulds, locked mode as power with hydraulic pressure.During matched moulds, the gas between piston and the drive end bearing bracket is extruded from the turnover gas passage that is communicated with working cylinder drive end bearing bracket piston rod hole by piston, and during die sinking, Compressed Gas enters cylinder body by this passage and promotes piston and retreat die sinking.This structure tends to the problem that die sinking is slow or pause takes place, and influences the speed of service of whole device.In order to address this is that, the employing that has increases the way of compression pressure, perhaps, reduce the slipper seal degree of piston and working cylinder and dwindle diameter of cylinder, but three's effect is all not obvious, and afterwards both are easier causes problems such as leakage of oil and clamp force are not enough.
Summary of the invention
Technical problem to be solved in the utility model provides the drive end bearing bracket of the blower for plastic bottle opening-closing lock die device working cylinder of architecture advances, and it can make working cylinder overcome above-mentioned defective.For this reason, the utility model by the following technical solutions: it comprises the piston rod hole, and the drive end bearing bracket sidewall has the turnover gas passage that communicates with the piston rod hole, has the check valve that communicates with turnover gas passage in the drive end bearing bracket rear wall.The inventor thinks, the reason that produces the problems referred to above is the moment in die sinking, has produced vacuum between piston end surface and the drive end bearing bracket rear wall, has influenced opening speed thus, owing to adopt above technical scheme, the utility model is simple in structure, and during matched moulds, air is discharged from the turnover gas passage that is communicated with the piston rod hole, exhaust is unobstructed, during die sinking, compressed air enters cylinder body by check valve simultaneously and directly acts on piston from the drive end bearing bracket rear wall, and the die sinking process is easily quick.
Described check valve comprises the air inlet mouth that is opened in the drive end bearing bracket and passes in and out the valve seat that the gas passage communicates, and is provided with the spool that cooperates with the air inlet mouth in the valve seat, is provided with the termination that is connected with valve seat that is connected with its elasticity behind the spool, and the termination has through hole.The utility model adopts this check valve, and is simple in structure easy for installation.
The termination is threaded with valve seat.Convenient for assembly like this and the dismounting.
The perisporium in piston rod hole has annular groove, and turnover gas passage communicates everywhere in annular groove with the piston rod hole.Like this, can help exhaust.

Fig. 2 is assembled to schematic diagram in the working cylinder for the utility model.
The specific embodiment
With reference to accompanying drawing 1.The utility model comprises piston rod hole 1, and drive end bearing bracket sidewall 2 has the turnover gas passage 3 that communicates with the piston rod hole, has the check valve 4 that communicates with turnover gas passage in the drive end bearing bracket rear wall 19.
Check valve 4 comprises the air inlet mouth 5 that is opened in the drive end bearing bracket and passes in and out the valve seat 6 that the gas passage communicates, and is provided with the spool 7 that cooperates with the air inlet mouth in the valve seat, is provided with the termination that is connected with valve seat 8 that is connected with its elasticity behind the spool, and the termination has through hole 9.Drawing reference numeral 10 is a spring.
The termination is threaded with valve seat.
The perisporium in piston rod hole has annular groove 11, and turnover gas passage communicates everywhere in annular groove with the piston rod hole.
With reference to accompanying drawing 2.Drawing reference numeral 12 is the power cylinder of blower for plastic bottle opening-closing lock die device, drawing reference numeral 13 drive end bearing brackets, end cap in the drawing reference numeral 14, has piston 15 in the cylinder body between drive end bearing bracket and the middle end cap, piston 15 promotes to advance by the hydraulic oil between middle end cap and the piston 15, piston rod 16 cooperates with front piston rod hole wall 17 slipper seals of drive end bearing bracket, and turnover gas passage is communicated with cylinder body by rear piston bar hole 18.
