Summary of the invention
In view of the deficiency that prior art exists, the purpose of this utility model is intended to provide a kind of and gathers the mould and the automatic locking die device of the EVA foaming machine of locked mode automatically, and can arbitrarily adjust the distance between moving, the cover half fixed head.
The utility model is finished as follows: it comprises the cover half fixed head that links to each other with support, be positioned at the dynamic mould fixing plate of cover half fixed head top, be located at moving, set of molds between the cover half fixed head, the column that passes the cover half fixed head and fuse with lower support plate, toggle formula automatic locking die body is set between described cover half fixed head and lower support plate, this toggle formula automatic locking die body comprises be hinged symmetrically arranged upper pendulum bar and draft link, be located at middle connecting plate and oil cylinder between upper pendulum bar, described upper pendulum bar upper end is connected with the cover half fixed head, described draft link lower end is connected with lower support plate, piston rod on the described oil cylinder is fixed on the cover half fixed head, its cylinder body links to each other with middle connecting plate, the connecting rod of symmetry is set on the upper pendulum bar of described symmetry, and described middle connecting plate is connected on the connecting rod of symmetry.
Above-mentioned dynamic mould fixing plate is connected with column by Adjusting bolt Adjusting screw, and described Adjusting bolt Adjusting screw is by thrust bearing, lock sleeve axial restraint, and by the reducing motor transmission.
Above-mentioned upper pendulum bar is hinged on the cover half fixed head through upper branching holder, and draft link is hinged on the lower support plate through the lower support seat.
The utility model compared with prior art, entire mechanism only need matched moulds and automatically locked mode, two actions of die sinking just can finish the required function of make-up machine, move simple and reliable and use, easy to maintenance.Can arbitrarily adjust simultaneously the distance between moving, the cover half fixed head, but reach set of molds space free adjustment, being applicable to the set of molds of any specification, and make set of molds in conjunction with closely.Entire mechanism has only an oil cylinder, and close look at the swing, oil circuit are simply smooth and easy, and locked mode is steadily reliable, and die sinking is rapid, and operating efficiency is high.
