Quick changing device for vertical injection molding machine

Abstract

The invention discloses a quick changing device for a vertical injection molding machine. The quick changing device for the vertical injection molding machine comprises an injection molding machine body and a mold, wherein the mold is located on the injection molding machine body; a carrying table is connected to one side of the injection molding machine body; a motor fixing plate is connected tothe other side of the injection molding machine body; a first drawing die motor and a second drawing die motor are arranged on opposite positions of the motor fixing plate and the carrying table; winding rollers are connected onto the first drawing die motor and the second drawing die motor; and drawing die steel wire ropes wind on the two winding rollers and are connected with opposite vertical surfaces of the mold. The quick changing device for the vertical injection molding machine further comprises a switching assembly for controlling the mold to stop moving. The quick changing device is additionally arranged on the injection molding machine, and the electric motors are utilized for replacing manpower to move the mold, so that the manual operation can be reduced, and the changing efficiency is improved; the mold has no need to be lifted, so that the safety coefficient is high; and in addition, through additionally arranging the switching assembly, the mold can be ensured to accurately stop moving, so that the trouble of manual fine-adjusting is avoided.

Description

technical field [0001] The invention relates to the field of injection molding equipment, in particular to a quick type change device for a vertical injection molding machine. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. It is divided into vertical, horizontal or all-electric, and the injection molding function The plastic is heated and high pressure is applied to the molten plastic, causing it to shoot out and fill the mold cavity. [0003] The problems of traditional vertical injection molding machines when converting molds are: [0004] 1. The location of the injection molding machine is limited. During the production of the injection molding machine, the mold (each set of mold weighs about 300-600KG) needs to be hoisted to the front of the injection ...

AI Technical Summary

Problems solved by technology

[0004] 1. The location of the injection molding machine is limited. During the production of the injection molding machine, the mold (each set of mold weighs about 300-600KG) needs to be hoisted to the front of the injection molding machine, which has a high safety risk;

[0005] 2. The structural limitation of the injection molding machine. During the process of changing the type, the operator needs to use the hand and the crowbar to push the mold to the center of the injection molding machine bit by bit in an oblique manner, and the efficiency of the type change is too high. Low;

[0006] 3. The nozzle of the injection molding machine needs to be in parallel with the glue inlet of the mold. The technician needs to use the hand and the crowbar to adjust the mold by oblique shifting until it is adjusted to the correct position. If there is a position deviation It will lead to poor glue feeding and overflow problems in production, which cannot guarantee the normal production and product quality
