Linear guide rail-guided mold clamping mechanism compatible with various power combinations

Abstract

The invention discloses a linear guide rail-guided mold clamping mechanism compatible with various power combinations. The mold clamping mechanism comprises a mold clamping fixed plate, a mold clamping movable plate and a mold clamping tail plate, wherein pull rods are fixedly arranged at four corners of the mold clamping fixed plate, the pull rods penetrate through the mold clamping movable plate and are fixedly arranged on the mold clamping tail plate, and a mold is placed between the mold clamping movable plate and the mold clamping fixed plate; and a first mounting interface and a second mounting interface are formed in the mold clamping tail plate, the first mounting interface and the second mounting interface are used for mounting a hydraulic power assembly and an electric power assembly separately, and the output end of the hydraulic power assembly and the output end of the electric power assembly are connected with the left end and the right end of a cross head separately. Through novel structure layout, the linear guide rail-guided mold clamping mechanism can be compatible with various power combinations, and can be compatible with hydraulic power or electric power under the condition that the main body structure is not changed. Therefore, any power combination is achieved, and the requirements of different products are met. A full-hydraulic mold clamping mechanism, a hybrid power mold clamping mechanism or a full-electric mold clamping mechanism is achieved.

Description

technical field [0001] The invention belongs to the technical field of mold clamping mechanisms for injection molding machines, and in particular relates to a mold clamping mechanism guided by linear guide rails compatible with various power combinations. Background technique [0002] The existing clamping mechanism can only use hydraulic power, or hybrid power, or one of all electric power. In order to meet customer needs, if these products are produced, different clamping modules need to be produced correspondingly, which increases the types of parts, prolongs the delivery cycle, and wastes production. [0003] In the existing mold locking mechanism, when the mold locking movable plate is guided by a linear guide rail, the slider of the linear guide rail is directly connected with the mold locking movable plate, causing the upper and lower asymmetry of the mold locking movable plate. Moreover, the mold locking movable plate will definitely deform during the process of gen...

In order to meet the needs of customers, if these products are produced, different clamping modules need to be produced correspondingly, which increases the types of parts, prolongs the delivery cycle, and wastes production

[0003] In the existing mold locking mechanism, when the moving plate of the mold locking is guided by a linear guide rail, the slider of the linear guide rail is directly connected with the moving plate of the mold locking, which causes the upper and lower asymmetry of the moving plate of the mold locking

Moreover, the mold locking movable plate will definitely deform during the process of generating clamping force with the mold locking fixed plate, and because the mold locking movable plate is directly connected with the linear guide rail, the deformation of the mold locking movable plate will inevitably be transmitted to the linear guide rail, resulting in The linear guide rail bears not only the gravity of the clamping movable plate and the mold, but also the huge eccentric load generated by the clamping force

This will lead to a decrease in the life of the linear guide, or in order to meet the demand, a larger specification of the linear guide must be selected, resulting in an increase in cost
