Platen Support Guide for Two-Platen Injection Molding Machines

Abstract

The invention discloses a formwork supporting and guiding device applied to a two-plate-type injection molding machine. The formwork supporting and guiding device applied to the two-plate-type injection molding machine is large in supporting load, adjustable in orientation and small in formwork moving resistance. According to the technical scheme, the formwork supporting and guiding device applied to the two-plate-type injection molding machine is characterized by comprising a machine frame track arranged horizontally and formwork supporting feet with grooves. The top surface and the lateral surfaces of the machine frame track are provided with supporting adjustment modules abutting against the grooves. Each supporting adjustment module comprises a first wedge block in sliding fit with the machine frame track and a second wedge block fixedly connected with the corresponding formwork supporting foot, wherein a middle block is arranged between the first wedge block and the second wedge block in an abutting mode. Each supporting adjustment module is further provided with an adjustment assembly used for adjusting the distance between the bottom surface of the corresponding first wedge block and the top surface of the corresponding second wedge block. A movable formwork can be adjusted in three directions through the supporting adjustment modules, thereby being stably and accurately arranged on the machine frame track. The requirements for the machining accuracy of a machine frame and the formwork are lowered. The cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to a template supporting and guiding device for a two-platen injection molding machine. Background technique [0002] The two-plate plastic injection molding machine abandons the twisted mechanical mold clamping structure, and adopts a high-pressure cylinder hydraulic mold clamping mechanism, which realizes rapid mold opening and closing and low-pressure mold protection through symmetrical mold shifting cylinders, and uses a brake mechanism to realize the fixing of the movable platen and tie rods. The four pistons in the fixed template drive the pull rod to generate a constant clamping force under the action of high-pressure oil, ensuring the stability and repeatability of product injection molding. High repeatability refers to the deviation of multiple products produced in the same batch. smaller. [0003] Two-plate plastic injection molding machine has a long ...

Problems solved by technology

The linear guide rail is used to support the guide, and the Gelin column only bears the clamping force, the overall length can be shortened, and the life of the seal of the clamping cylinder can be improved, but the linear guide rail bears a large load, the cost of components increases, and the processing accuracy of the frame and template is high; The structure of sliding block support and Gelin column guide is adopted, the height and center of gravity of the formwork can be adjusted, which improves the mold bearing capacity of the whole machine. As the column length increases, the self-weight deformation of the Corinthian column increases the friction coefficient between the mobile formwork and the Corinthian column, increases the resistance of the mold moving, and has a certain impact on the performance of the clamping cylinder seal, increasing hydraulic oil leakage risks of
