Fixing structure of plastic mould

Abstract

The invention relates to the technical field of plastic moulds, in particular to a fixing structure of a plastic mould. The centers of the two sides of the upper end of a base are fixedly provided with supporting plates respectively, the centers of the corresponding sides of the two supporting plates are provided with hydraulic telescopic rods respectively, output shafts of the two hydraulic telescopic rods are connected with extrusion boxes respectively, the two extrusion boxes conduct limiting through sliding mechanisms, bearings penetrate through the two sides of the two extrusion boxes respectively, the inner sides of the two extrusion boxes are provided with screw rods respectively, the two ends of the screw rods penetrate through the bearings and extend to the outer sides of the extrusion boxes, the two ends of the two screw rods are provided with rotary knob respectively, the outer sides of the two ends of the two screw rods are provided with sliding blocks respectively, the corresponding sides of the sliding blocks are connected with connecting blocks respectively, the two ends of the corresponding sides of the two extrusion boxes are provided with sliding grooves respectively, the connecting blocks penetrate through the sliding grooves and extend to the outer sides of the extrusion boxes, and the other ends of the connecting blocks are fixedly provided with limiting plates respectively. The fixing structure of the plastic mould has the advantages that the structure is simple, the plastic moulds with different sizes can be fixed rapidly, the fixing effect is good, and the efficiency is quick.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to a fixing structure for plastic molds. Background technique [0002] Plastic mold, an abbreviation for a combined plastic mold for compression molding, extrusion molding, injection, blow molding and low foam molding. [0003] In the process of plastic mold processing, in order to prevent the mold from sliding and reduce the precision of processing, it is necessary to use a mold fixing structure to fix the mold to improve the stability of plastic mold processing. Therefore, the use of mold fixing structures is more common; existing The fixed structure has certain disadvantages in use. In order to meet different use requirements, the size of the plastic mold is different, and the fixed structure cannot be adjusted according to the size of the processing mold. The scope of use is limited, which causes the use of the fixed structure. To a certain extent, for this reason, we pro...

[0003] In the process of plastic mold processing, in order to prevent the mold from sliding and reduce the precision of processing, it is necessary to use a mold fixing structure to fix the mold to improve the stability of plastic mold processing. Therefore, the use of mold fixing structures is more common; existing The fixed structure has certain disadvantages in use. In order to meet different use requirements, the size of the plastic mold is different, and the fixed structure cannot be adjusted according to the size of the processing mold. The scope of use is limited, which causes the use of the fixed structure. To a certain extent, for this reason, we propose a fixed structure for plastic molds
