Abstract

The invention relates to a force expansion type dual-template mould clamping mechanism using four boosting cylinders. Two mould closing oil cylinders are arranged on mould closing cylinder seats; a head plate is connected with a fixed mould; the mould closing oil cylinders are in drive connection with movable seat plates which are connected with moving moulds; a boosting mould clamping oil cylinder is arranged on the moving mould seat plate; the body of the boosting mould clamping oil cylinder is integrated with the moving seat plate; the boosting cylinder is divided into a first group of boosting cylinder and a second group of boosting cylinder by a piston of the boosting mould clamping oil cylinder; a nut mounting plate is arranged on the piston of the boosting mould clamping oil cylinder; a split nut is arranged on the nut mounting plate; the body of a split oil cylinder is in drive connection with half of the split nut; a piston of the split oil cylinder is in drive connection with the other half of the split nut; and the body of the split oil cylinder is divided into a third group of boosting cylinder and a fourth group of boosting cylinder by the piston of the split oil cylinder. In the invention, the mould closing can be realized by adopting two mould closing oil cylinders to drive the moving seat plates and the force expansion and the mould clamping can be realized by adopting four boosting oil cylinders. The mould closing and clamping mechanism has simple structure and high mould locking action and is stable and reliable.

Description

technical field [0001] The invention relates to a mold clamping mechanism, in particular to a four-pressurized-cylinder expansion type double-platen mold clamping mechanism. Background technique [0002] With the intensification of energy crisis and environmental pollution, the concept of low-carbon economy has been put forward, and lightweight and low energy consumption have attracted more and more attention from all countries in the world, becoming the development direction of the future manufacturing industry. It is an inevitable trend in the development of the manufacturing industry that light alloy parts gradually replace some ferrous metal parts. Therefore, the market demand for die casting machines and squeeze casting machines has gradually increased in recent years. [0003] Early die-casting machines had clamping mechanisms driven by a single oil cylinder. This mechanism was simple in structure and reliable in action. However, due to the large diameter of the oil cy...
