Multi-station framework switching structure of injection machine

Abstract

The invention belongs to an injector multiple-station mold plate exchange structure, which comprises a moving mold component and a hanging mold component, wherein the moving mold component comprises a moving mold bracket and a moving mold seat positioned on the moving mold bracket. A mold plate frame used for supporting a lower mold plate is arranged on the moving mold seat and a supporting plate used for the horizontal displacement of the lower mold plate and the mold plate frame is also connected to the mold plate frame. A moving mold seat lifting device capable of driving the moving mold seat to move up and down, a mold plate frame exchange device and a moving mold seat positioning device are arranged on the moving mold bracket. The hanging mold component comprises a static mold plate and a dynamic mold plate, wherein a hanging mold seat used for supporting the mold plate frame is arranged between the still mold plate and the dynamic mold plate. The mold plate frame which can be exchanged with the mold plate frame on the dynamic mold seat is arranged on the hanging mold seat and a hanging mold seat lifting device, a horizontal moving device making the hanging mold seat move back and forth and a hanging mold seat positioning device are arranged below the mold plate frame. The mold plate exchange structure has the advantages of compact structure, high butt joint precision, precise and stable repeated butt joint and positioning precision and safe and reliable use.

Description

technical field [0001] The invention relates to a rubber injection technology, in particular to a multi-station template exchange structure for a rubber injection machine. Background technique [0002] In the prior art, the multi-station template exchange structure of the injection machine includes the mold shifting assembly for conveying the template frame, and the mold molding parts for injection molding. Since rubber injection requires a certain clamping pressure, it is generally used for There is a high clamping pressure, and the lifting mold assembly is usually used to achieve the purpose of mold forming. [0003] But at present, the docking positioning of the mold shifting assembly and the formwork frame in the hanging mold assembly is mainly realized through the electrical control system composed of travel switches and displacement sensors. The disadvantage of this docking positioning is: the mold shifting assembly 1. It is difficult to achieve complete consistency i...

[0003] But at present, the docking positioning of the mold shifting assembly and the formwork frame in the hanging mold assembly is mainly realized through the electrical control system composed of travel switches and displacement sensors. The disadvantage of this docking positioning is: the mold shifting assembly 1. It is difficult to achieve complete consistency in the height of the hanging mold components. Repeated docking positioning accuracy is low, unstable and unsafe. It is often easy to cause mechanical damage and safety production accidents due to inaccurate docking positioning. When the control system fails It is also easy to cause damage to the guide rail of the machine due to inaccurate docking positioning and cause safety production accidents
