Back elevation clamp of initial die

Abstract

The invention discloses a back elevation clamp of an initial die. The back elevation clamp comprises a turntable tailstock bridge plate structure, self-centering locating and clamping mechanisms and lateral locating mechanisms. A main board of the turntable tailstock bridge plate structure is provided with two sets of self-centering locating and clamping mechanisms, and the lateral locating mechanisms are arranged in front of the self-centering locating and clamping mechanisms. The back elevation clamp has the beneficial effects that one cylinder drives one mechanism, four pressing plates are controlled simultaneously, the die is compressed, and the centering effect is realized, so that the production precision is guaranteed, and the processing yield is improved; operation of processing parts is convenient, adjusting while remodeling is convenient, and the work time is saved; furthermore, the clamp is a double-station clamp, two parts can be processed at a time, processing contents on two faces can be processed at a time through the turntable tailstock bridge plate structure, the cost is reduced, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of mold fixtures, in particular to a fixture for the back elevation of a mold forming a blank. Background technique [0002] The initial mold is a mold for producing various bottles. The production and processing of this kind of mold needs to process the keyway and hole on one end a of the mold and the outer surface b of the mold according to the outer circle positioning of the mold itself. The mold is a series of semicircular parts with different diameters and lengths. Before processing the parts, the outer circle of the parts has been finely turned. [0003] In the past, this process was performed with a vise clamped in the machining center, and the process size and accuracy requirements were met through multiple calibrations. The disadvantages of this kind of processing are: to process the above content, the parts need to be clamped twice, the repeated positioning is not good, and the outer circle cannot be self-c...

AI Technical Summary

Problems solved by technology

The disadvantages of this kind of processing are: to process the above content, the parts need to be clamped twice, the repeated positioning is not good, and the outer circle cannot be self-centered, resulting in deviation of the outer circle when the concave and convex molds are combined, there is no precise positioning, and the tool needs to be adjusted every time , the size of the parts is unstable, and the production efficiency is low, and it is troublesome to replace the parts
