Automatic pouring PU (Polyurethane) earplug manufacturing device

Abstract

The invention discloses an automatic pouring PU (Polyurethane) earplug manufacturing device. The automatic pouring PU (Polyurethane) earplug manufacturing device comprises a rack, wherein X-axis guide rails and X-axis driving mechanisms are arranged on the rack, a cantilever which can move along the guide rails is arranged on the X-axis guide rails, Y-axis guide rails and Y-axis driving mechanisms are arranged on the cantilever, an automatic color matching and injection mixing device which can move along the guide rails is arranged on the Y-axis guide rails, an earplug mold permanent seat and an automatic line feed mold opening and closing actuator are arranged at one end of the rack, multiple earplug molds are arranged on the permanent seat at intervals, and a water heating circulating device with double pipelines, which is used for heating each earplug mold, is also arranged at one side of the rack. The automatic pouring PU (Polyurethane) earplug manufacturing device has a self-timing mold opening and closing function and can be used for ensuring that products reach physical property requirements within setting time; and by adopting the automatic pouring PU (Polyurethane) earplug manufacturing device, the product quality is ensured, after mold opening, the products are separately molded, and secondary machining is not needed, so that raw materials are saved, and the efficiency is high.

Description

technical field [0001] The invention relates to manufacturing equipment, in particular to an automatic perfusion PU earplug manufacturing device. Background technique [0002] In the prior art, there is a kind of equipment for producing PU earplugs, which uses preheating and then manually placed on the workbench for perfusion, manual perfusion is uneven, the weight and physical properties of the product cannot be guaranteed, and the efficiency and quality cannot be guaranteed. After pouring, the mold is manually closed and opened, and the mold is operated separately. The traditional discharge nozzle is one, and the product is formed into a whole piece. It needs secondary processing (cutting) to be the finished product, and the remaining material after cutting is scrapped. The production efficiency is low and the production cost is high. The color paste is added in the A raw material tank and mixed with the A raw material. To change the color, use a large amount of A raw mat...

Problems solved by technology

[0002] In the prior art, there is a kind of equipment for producing PU earplugs, which is preheated first and then manually placed on the workbench for perfusion. Manual perfusion is uneven, and the weight and physical properties of the product cannot be guaranteed, and the efficiency and quality cannot be guaranteed.

After pouring, manual mold closing, mold opening, and separate mold operation. The traditional discharge nozzle is one, and the product is formed into a whole piece. It needs secondary processing (cutting) to be the finished product, and the remaining material after cutting is scrapped.

Low production efficiency and high production cost

The color paste is added in the A raw material tank and mixed with the A raw material. To change the color, use a large amount of A material to clean the original color in the metering system and pipeline, which will waste the A material
