Inner sliding block contraction mould

Abstract

Disclosed is an inner sliding block contraction mould. The inner sliding block contraction mould comprises a bottom plate, a plurality of guiding blocks evenly distributed on the bottom plate in the circumferential direction of the center of the bottom plate and an upper cover plate fixed to the guiding blocks. A plurality of first sliding blocks, second sliding blocks used for driving the first sliding blocks to slide towards the outer side and tapered wedges used for driving the second sliding blocks to slide towards the outer side are arranged between the bottom plate and the upper cover plate. The first sliding blocks and the second sliding blocks are located at the peripheries of the tapered wedges. Each first sliding block is mounted on the corresponding guiding block in a sleeving mode. Each second sliding block is located between the two adjacent first sliding blocks. The inner side faces of the first sliding blocks and the second sliding blocks are connected with reset mechanisms used for driving the first sliding blocks and the second sliding blocks to slide towards the center. The inner sliding block contraction mould has the distraction and contraction functions, in theworkpiece forming process, a workpiece is supported and abutted against through the distracted first sliding blocks and the distracted second sliding blocks; and after workpiece forming, the first sliding blocks and the second sliding blocks are contracted, the workpiece is taken out, and machining of inward folding or the pressure level of a round barrel body part is facilitated.

Description

technical field [0001] The invention relates to an inner slider shrinkage mold. Background technique [0002] In the existing technology, such as Figure 9-14 As shown in , most of the circular drum body workpieces need to be folded inward or pressed inwards at both ends of the workpiece due to assembly. When folding or pressing, the workpiece must be supported by a structure (core) in order to be formed. However, the problem is that when the size of the mold core inside the workpiece matches the size of the workpiece, the workpiece cannot be removed after molding; the size of the mold core is too small, and the mold core and the workpiece are rotated during production on the equipment , The mold core cannot completely position the workpiece, which will cause the workpiece to shake, left and right, resulting in unstable dimensions of the workpiece after processing, out-of-round deformation, displacement, unclear outline, and high scrap rate. [0003] Therefore, further imp...

However, the problem is that when the size of the mold core inside the workpiece matches the size of the workpiece, the workpiece cannot be removed after molding; the size of the mold core is too small, and the mold core and the workpiece are rotated during production on the equipment , the mold core cannot completely position the workpiece, which will cause the workpiece to shake, suddenly left and right, resulting in unstable dimensions of the workpiece after processing, out-of-round deformation, displacement, unclear outline, and high scrap rate.
