Description

Technical Field

[0001] The utility model relates to the technical field of mold injection molding, and more specifically, it relates to an injection molding device for producing an aviation alarm shell. Background Art

[0002] In the existing technology, firstly, some devices do not have a mold transportation mechanism, and the movement and positioning of the mold may need to be done manually, which increases labor intensity and reduces production efficiency. Manual operation may cause inaccurate mold positioning, affecting the accuracy and consistency of the product. The mold replacement and positioning time is increased, which reduces the speed and output of the production line.

[0003] Secondly, lack of lubrication in some devices may lead to increased friction between moving parts, accelerated wear, and shortened equipment life. Equipment wear may lead to instability in the production process, such as increased temperature, decreased precision, and other problems. Due to increased wear, more frequent maintenance and parts replacement may be required, increasing maintenance costs. Finally, some devices may cause uneven lubrication, affecting the lubrication effect of the equipment. Insufficient lubrication may cause equipment overheating or failure, affecting the safety of operators. Lubrication auxiliary mechanisms are usually coordinated with automation systems. The lack of this mechanism may lead to a reduced level of automation, affecting production efficiency and product quality. Utility Model Content
