Auxiliary rotary table for forming multi-color mold by single-color machine

Abstract

The invention discloses an auxiliary rotary table for forming a multi-color mold by a single-color machine. The rotary table comprises a base, a horizontally arranged rotary table is arranged at the upper end of the base, a central rotating shaft is arranged at the upper end of the rotary table, teeth are arranged at the lower end of the peripheral edge of the rotary table, the teeth are meshed with a correspondingly matched driving gear set, and the driving gear set is fixedly arranged at the upper end of the base. The driving gear set is connected with a driving motor, a plurality of concave positioning concave blocks and sensor contact blocks are arranged at the upper end of the edge of the periphery of the rotary table, positioning convex blocks correspondingly matched with the positioning concave blocks are arranged at the upper end of the base, the positioning convex blocks are connected with positioning air cylinders, and sensors corresponding to the sensor contact blocks are arranged at the upper end of the base. A plurality of pressing wheels are arranged at the side end of the periphery of the rotary table, arranged on the upper end faces of the teeth and arranged at the upper end of the base through pressing wheel fixing seats. The auxiliary rotary table has the advantages of being novel in design, simple in structure, accurate in positioning, capable of being used for multi-color mold injection molding, low in cost and good in injection molding effect.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an auxiliary turntable for forming multi-color molds by a single-color machine. Background technique [0002] With the development of society, injection molding machines are used more and more widely. Even in the continuous updating of injection molding machines, some new problems will appear. Existing injection molding machines have hydraulically driven turntables that rotate slowly, which affects the production cycle of injection molding products, and During the rotation process, the acceleration and deceleration are not stable, and there is a large impact. In addition, the existing turntable generally can only rotate 180 degrees back and forth, and the positioning is not accurate, so only two-color injection molding can be realized, and three-color or multi-color injection molding cannot be realized. Contents of the invention [0003] The object of the present invention is t...

Problems solved by technology

[0002] With the development of society, injection molding machines are used more and more widely. Even in the continuous update of injection molding machines, some new problems will appear. The existing hydraulic drive turntable of existing injection molding machines rotates slowly, which affects the production cycle of injection molding products, and Acceleration and deceleration are not stable during the rotation process, and there is a large impact

In addition, the existing turntable generally can only rotate 180 degrees back and forth, and the positioning is not accurate, so only two-color injection molding can be realized, and three-color or multi-color injection molding cannot be realized
