BMC Bakelite injection molding machines for elastic movable platen

Date：2016-06-14 13:23:37

Existing common Bakelite injection molding machine, including the transom, stationary platen and the movable platen, tailgate and set the template to the rack, between the end plate and the connecting rod fixed templates, dynamic templates provided in the end plate and the stationary platen the lever between the stationary platen and the movable platen by gripping the mold, injection molding, the current dynamic template for the box-like movable platen, the front end surface of the mold mounting surface, which includes the main movable platen hinged ear, rod guide holes, mold fixing holes, the top of the hole, the movable platen hinged ear subject to a rectangular plate, symmetrical moving up and down in the middle ear template hinge body on the rear panel are provided 2-4 hinge ear, moving template hinge ear four corner portions of the main body has a rod guide holes respectively, in the central mold mounting surface of the movable platen hinged ear mold body provided with fixing holes and the top of the hole, the mold mounting hole for fixing a die mounted on the mounting surface of the mold, the top of the hole for the workpiece ejection from the mold, the downside is that due to the movable platen hinged ear body structure as a whole, in the mode-locking process, when the movable platen hinge hinge ear ear pushing the body moves, the movable platen action will be deformation resistance, with the clamping force continues to increase, so that the lever is elastically stretched, so that the movable platen hinged ear bending deformation of the body, resulting in a template mounting surface movable platen hinged ear body deformation, affecting products accuracy and die life.
The BMC injection molding machine contents of this utility model aims to  provide a simple structure, even by force, can be reduced in the process Dianmu injection molding machines for the elastic deformation of the movable platen force. In order to achieve the above object, the technical scheme of the utility model is used in injection molding machine Bakelite ELASTODYNAMIC templates, including hinge ear, ear hinge body movable platen, rod guide hole, the hole and the top of the mold fixing holes in the movable platen hinged ear central rear body panel are provided vertically symmetrically from 2-4 pivotal connection, the front end of the movable platen is hinged ear mold mounting surface of the body, the four corner portions of the movable platen are respectively provided with hinge ears rod body guide hole, in mold mounting surface of the movable platen hinged ear mold body is provided with the front end of the fixing holes and the top of the hole, characterized in that the central movable platen hinged ear body top and bottom walls are provided with deep grooves. The length of the utility model also implement the following measures by the groove is greater than the distance between the two outermost outer edge of the hinge between the ears. The utility model has the advantages that the structure is simple, even by force, in the process reducing the stress and deformation, to ensure the quality of injection molding.
