Abstract

The invention provides a mold opening and closing oil circuit of an injection molding machine. The mold opening and closing oil circuit comprises an oil circuit body, wherein the oil circuit body comprises a mold opening and closing oil cylinder, a first reversing valve, a second reversing valve, a damper and an oil tank; the mold opening and closing oil cylinder is arranged at the top end of the oil circuit body, and connected with the first reversing valve and the second reversing valve; the first reversing valve is connected with the damper; and the oil tank is arranged at the bottom of the oil circuit body. According to the mold opening and closing oil circuit provided by the invention, various functions of rapid mold closing (differential motion), mold closing, low pressure mold closing, high-pressure mold locking, slow mold opening, rapid mold opening and the like can be realized by only two two-station three-way reversing valves, so that operation procedures are reduced, the working efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of injection molding machine oil passages, in particular to an injection molding machine mold opening and closing oil passage. Background technique [0002] The existing standard model mold opening and closing oil circuit is generally composed of mold opening and closing valves, internal (external) differential valves, and back pressure valves. The above configuration requires 4 to 5 valves, a large number of reversing valves, and complex valve block design , need to have forming tool processing, high processing cost and long processing cycle. Therefore, in order to save costs, it is necessary to design and develop a new mold opening and closing oil circuit for small injection molding machines. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a method that only needs two two-position three-way reversing valves to realize f...
