Raw material weighing device for bumper injection molding

Abstract

The invention relates to the technical field of weighing devices for injection molding, and discloses a raw material weighing device for bumper injection molding. The device comprises a device body, aweighing device body is fixedly mounted on the top of an inner cavity of the device body, the bottom end of the weighing device body is fixedly provided with supporting legs, the bottom ends of the supporting legs are fixedly provided with weighing sensors, a moving disc is arranged under the bottom end of the weighing device body, and a moving air cylinder is fixedly mounted on the right side ofthe moving disc. According to the raw material weighing device for bumper injection molding, an electric telescopic rod, a raw material (auxiliary material) telescopic pipe and a distance sensor on the bottom of a stop disc are arranged, it can be ensured that in the raw material discharging process, opening and closing can be controlled through the stop disc, through up and down motion of the electric telescopic rod, the stop disc is always located above the raw material by about 2 cm in the discharging process, the raw material shortest falling distance can be controlled, and the raw material weighing precision can be ensured.

Description

technical field [0001] The invention relates to the technical field of weighing equipment for injection molding, in particular to a raw material weighing equipment for injection molding of bumpers. Background technique [0002] Most of the existing automobile bumpers are produced by injection molding or blow molding. During the production process, the raw materials and auxiliary materials need to be weighed and proportioned to make the bumpers meet different usage requirements, so weighing equipment is required. . [0003] When the existing weighing equipment weighs the raw materials, the raw materials are directly transported to the weighing equipment through the pipeline, but because the height of the pipeline is set higher than the carrier of the weighing equipment, the weighing equipment has been Identify the weight and close the valve of the pipeline as quickly as possible, but there are still raw materials that fall naturally in the air into the weighing equipment, wh...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a raw material weighing equipment for bumper injection molding, equipped with telescopic tubes to automatically adjust the height to obtain the lowest delivery port, so as to ensure that the raw materials can be cut off in time, ensure accurate quality control, stir and preheat after mixing, and ensure the texture of processed parts The advantage of good uniform quality solves the problem that when the existing weighing equipment weighs the raw materials, the raw materials are directly transported to the weighing equipment through the pipeline, but the height of the pipeline is higher than the carrier of the weighing equipment. , so that the weighing equipment has recognized the weight and the valve of the pipeline is closed as quickly as possible, but there are still raw materials falling naturally in the air into the weighing equipment, which leads to the problem that the raw materials are heavier than the predetermined mass
