Hydraulic circuit change feature of hydraulic head amount mold release tool

摘要

(57) Abstract Objective Opposing to the fixed dies, the operational dies the reciprocateThe hydraulic head amount mold release tool smell of having the piston which it can pointCorresponding to the hydraulic Drive source where the te and capacity differ, it stabilizes setting pressure,As the te it can maintain, without enlarging the tool itself structureThe relief valve which it tries to be able to simplify structure it finishes to be attached,Offer of changing valve gear is designated as purpose. Constitution Input port and printout portWith the change with external manipulation means in the oilway with the pistonsDoing the supply change of the pressure oil with manipulation, the reciprocate of the pistonThe change-over valve by the abbreviation tubular Simultaneous Peripheral Operation On-Line valve which it makes do facilitiesInside ke and the said change-over valve receiving pressure oil of input port sideThe pressure relief valve by the poppet valve which possesses the ru pressure receiving aspect taking inThe equipment to do, the excessive pressure oil of the input port side oilway aforementioned ririDirectly in the printout port side oilway via the hu valve with returningIn order to finish, it features that it constitutes.
