Automatic fetching device of injection molding machine

Abstract

The invention relates to an automatic fetching device of an injection molding machine, which comprises an injection molding machine frame, wherein the machine frame is provided with an injection device; a fixed die plate on the machine frame is connected with a movable die plate and a back die plate through guide posts; the fixed die plate and the movable die plate are respectively provided with an injection die; a die cavity is arranged in the injection die; a fetching plate is arranged in the machine frame; a material absorption device and a push-out device are arranged in the fetching plate; the fetching plate is driven by an elevating gear; and the elevating gear is installed on a steady rest. The invention is characterized in that the elevating gear comprises a fixed rack arranged inthe fixed rack and an elevating guide rail, the fetching plate is connected with the elevating guide rail, one side of the fetching plate is provided with a movable rack, and the movable rack and thefixed rack mesh with the elevating gear driven by power. In the scheme of the invention, the elevation of the fetching plate is controlled by a multiple-path mechanism, which is formed by that the movable rack and the fixed rack mesh with the elevating gear, and the stroke of the fetching plate can be multiplied by twice or more than twice; and thus, the invention reduces the occupation space, decreases the height of the machine frame, has a high elevation speed, shortens the time and enhances the work efficiency.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to an automatic feeding device for an injection molding machine, and belongs to the field of plastic machinery. Background technique [0002] When the injection molding machine is processing products, it is necessary to take out the molded products (materials, including plastic bottles, daily plastic parts, etc.) Mineral water bottles, tubes, and other plastic products. The existing methods of taking out the material from the injection mold include manual retrieving and mechanical retrieving, which are manually taken out from the mold. The disadvantages are slow speed, low work efficiency, high manual labor intensity, and easy to cause industrial accidents. Mechanical retrieving is to eject directly from the injection mold (there is an ejection mechanism in the mold) so that the material (product) falls freely, but it is directly ejected from the injection mold, the falling position ...

AI Technical Summary

Problems solved by technology

However, its disadvantage is that the reciprocating lifting motion is directly driven by the oil cylinder, and the piston stroke of the oil cylinder needs to be very long, so a large oil cylinder is required, which increases the cost, especially the machine has a large volume, a long stroke, and a slow reciprocating speed.

In addition, there is no suction device on the take-off plate, and the material is easy to fall off after being transferred from the injection mold to the take-off plate

In addition, there is no cooling device in the pick-up plate, the material after injection is soft, easily deformed after being dropped, and piled together
