Intelligent Production for Injection Molding

As time has passed, we have ushered in the Fourth Industrial Revolution. This revolution has driven the intelligentization and automation of production processes, greatly improving resource productivity and promoting the development of green energy.

I. Pain Points in Injection Molding Production

In the injection molding process, four sets of 56mm x 36mm metal sheets per mold need to be precisely placed into the injection molding machine and aligned with the two 2.5mm ejector pin holes.

Traditional manual operation is not only inefficient but also suffers from difficulties in operation, inaccurate placement, and safety hazards.

II. Technical Solution Analysis

Addressing the pain point of accurately feeding four sets of 56mm x 36mm metal sheets per mold in injection molding production, this design uses an injection fixture + dual-station automatic feeding rack + industrial robotic arm as the core combination to replace manual feeding. Starting from the three core needs of precise positioning, efficient operation, and safe production, it solves the problems of low efficiency, inaccurate positioning, and safety hazards associated with manual operation, achieving automated and standardized operation of feeding materials to the injection molding machine.

1.Injection Molding Fixture

This is a customized fixture specifically designed to precisely match the dimensions of four sets of 56mm x 36mm iron sheets per mold. It features pre-set positioning points that perfectly correspond to the 2.5mm ejector pin holes on the injection molding machine, enabling rapid engagement and precise positioning. This hardware-level design eliminates misalignment, ensuring accurate alignment with the ejector pin holes during material feeding and resolving positioning errors caused by manual material feeding.

2.Dual-Station Automatic Feeder

Serving as both a storage and feeding unit, this fixture can simultaneously perform two sets of storage and feeding operations, achieving continuous feeding without frequent manual replenishment or delivery. Combined with the operating cycle of the industrial robotic arm, it achieves seamless automatic feeding from the feeder and material retrieval by the robotic arm, significantly improving feeding efficiency.

3.Industrial Robotic Arm

As the core of the solution, it is equipped with a customized gripper that precisely grasps the metal sheets from the fixture and completes the precise transfer and unloading from the fixture to the injection molding machine according to a preset program. Its high-precision motion control ensures accurate alignment with the injection molding machine's ejector pin holes during unloading. Simultaneously, it can flexibly adjust its operating speed according to the production cycle, adapting to the batch feeding requirements of four sets of metal sheets per mold.

III. Core Value of the Solution

This technical solution, through a combination of customized hardware positioning and automated process operation, precisely solves the industry pain points of metal sheet feeding in injection molding. It replaces all core steps of traditional manual operation, achieving precise, efficient, and safe production of metal sheet feeding to the injection molding machine. It also improves the standardization level of injection molding production, reduces labor costs and defect rates, and lays the hardware and process foundation for subsequent automation upgrades of injection molding production lines. It possesses high practical value and feasibility.

After introducing this injection molding fixture and dual-station automatic feeder, manufacturing enterprises can increase production efficiency by more than 30%, significantly reduce the labor intensity of employees, and avoid the safety hazards associated with manual operation. Furthermore, by replacing the vibratory feeder with a dual-station automatic feeder, on-site noise is effectively controlled, improving work comfort and production efficiency. The successful application of this product has earned high recognition and praise from customers.
