Clamping device of injection molding machine mould

Abstract

The invention provides a clamping device of an injection molding machine mould, and the clamping device can be used for realizing quick, safe and reliable clamping of the mould, so that the clamping efficiency of the mould can be effectively improved, tool reserve can be reduced, and the production cost can be reduced. The clamping device comprises a compaction bolt, a clamping block and a cushion block, wherein the thickness of the cushion block is same to the thickness of flange of a mould installing end, and the cushion block is installed between the clamping block and an injection molding machine installing surface in a cushioning manner; the compaction bolt penetrates through the clamping block and compacts the clamping block on the mould and the cushion block, thereby clamping the mould on the injection molding machine installing surface. The clamping device provided by the invention is characterized in that the cushion block is connected with the clamping block through a side connecting block, and the clamping block and the cushion block are respectively connected with the side connecting block through a shaft pin I and a shaft pin II.

Description

technical field [0001] The invention relates to the technical field of clamping tools for injection molding machine moulds, in particular to a clamping device for injection molding machine molds. Background technique [0002] The two sides of the mold of the injection molding machine are fixed on two opposite installation surfaces 11 in the axial direction of the injection molding machine. When clamping, the clamp block 24 is pressed tightly on the flange part 10 of the mold clamping end surface by the bolt 22 to press the mold on the mold. On the mounting surface 11, a spacer 23 with the same thickness d' and the thickness d of the flange part 10 is placed between the clamp block 24 and the mounting surface 11 to ensure that the mold is evenly stressed so as to realize reliable clamping of the mold. See Figure 6 , its disadvantage is that: because the spacer 23 and the clamping block 24 are split structures, the clamping is inconvenient and the clamping efficien...

Problems solved by technology

[0002] The two sides of the mold of the injection molding machine are fixed on two opposite installation surfaces 11 in the axial direction of the injection molding machine. When clamping, the clamp block 24 is pressed tightly on the flange part 10 of the mold clamping end surface by the bolt 22 to press the mold on the mold. On the mounting surface 11, a spacer 23 with the same thickness d' and the thickness d of the flange part 10 is placed between the clamp block 24 and the mounting surface 11 to ensure that the mold is evenly stressed so as to realize reliable clamping of the mold. See Image 6 , its disadvantage is that: because the spacer 23 and the clamping block 24 are split structures, the clamping is inconvenient and the clamping efficiency is low. 22 tightening, since most of the injection molds are vertically installed and fixed, and the volume and quality of the fixed block 23 are relatively large, it is easy to injure people due to the fall of the cushion block 23 during clamping, and there is a greater potential safety hazard; At the same time, it is easy to appear that the cushion block 23 is not in place during the installation process, thereby causing the problem of unreliable clamping; in addition, the thickness d of the flange part 10 of different molds is different, and the cushion block 23 of the corresponding thickness is required. , thus increasing tooling reserves and high production costs
