[0002] In the injection molding industry, the precise feeding and positioning of small metal parts (such as iron sheets) has always been a technical challenge. For example, when placing four groups of 56mm long and 36mm wide iron sheets in a mold into an injection molding machine, the iron sheets need to be inserted into two 2.5mm ejector pin holes. Generally, the iron sheets are placed manually by traditional methods. For scenarios where four groups of iron sheets need to be fed simultaneously, manual operation is difficult to ensure that each iron sheet can be accurately placed into the ejector pin hole of the injection molding machine. In addition, manual operation is easily affected by factors such as the working environment and employee fatigue, resulting in unstable product quality. In view of this, this application is specially filed. Utility Model Content

[0016] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] Please see attached Figure 1-3 , an auxiliary positioning loading rack for an injection molding jig, comprising a base 1, a positioning block 2, an electromagnet 3, an ejector pin 4, an ejector sheet 5, a cylinder 6 and a material taking device, wherein the number of the positioning blocks 2 is four, and the positioning blocks 2 are respectively arranged at the four corners of one side of the base 1, and an L-shaped limit plate 8 is arranged at the outer edge of the top of the positioning block 2, and the electromagnets 3 are arranged on the top of the positioning blocks 2, and two groups of electromagnets 3 are arranged on the top of each positioning block 2, and the ejector pins 4 are symmetrically arranged on one side of the top of the positioning block 2, and the diameter of the ejector pin 4 is 2.5 mm, and the cylinders 6 are symmetrically arranged on both sides of the top of the base 1, and the cylinders 6 on both sides are located between the two positioning blocks 2, and the ejector sheet 5 is arranged on the output ends of the cylinders 6 on both sides, and the bottom of the ejector sheet 5 is respectively in contact with the tops of the four positioning blocks 2, and the ejector sheet 5 is in an I-shape, and the material taking device is arranged in the middle of the base 1.

[0020] With the above technical solution, when the robot arm moves the loading rack to the top of the iron sheet pile, the electromagnet 3 is energized to generate a magnetic field to absorb the iron sheet. Two groups of electromagnets 3 are set on the top of each positioning block 2 to ensure that the iron sheet is stable and does not fall off during the suction process, and can cope with iron sheets of different shapes and weights; the top of the positioning block 2 is symmetrically arranged with a pin 4 whose diameter is consistent with the pin 4 hole in the injection molding machine to ensure that the iron sheet can be accurately aligned when placed. The design of the pin 4 is not only used for positioning, but also as a guide, so that the iron sheet can slide smoothly into the pin 4 hole of the injection molding machine; after receiving the signal, the cylinder 6 pushes the ejector sheet 5 to move in the direction away from the base 1, and the ejector sheet 5 drives the iron sheet to move together until the iron sheet completely enters the mold of the injection molding machine. The I-shaped ejector sheet 5 design helps to evenly distribute the force and ensure that the iron sheet is smoothly placed; the L-shaped limit plate 8 on the outer edge of the top of the positioning block 2 is used to prevent the iron sheet from shifting during movement, further ensuring the accuracy of positioning;

[0021] The auxiliary positioning loading rack for the injection molding jig in the present application cooperates with each other by integrating components such as a robotic arm, an electromagnet 3, a ejector pin 4, a cylinder 6 and a pneumatic nozzle clamp 7, thereby realizing efficient and accurate loading of small iron sheets and removal of finished products. The overall process includes the absorption, positioning, placement of the iron sheets into the injection molding machine, and removal of the finished products after the injection molding is completed. The entire process is automated, which significantly improves production efficiency and reduces the risks and labor intensity of manual operation.

[0022] In some embodiments, the material taking device includes a pneumatic nozzle clamp 7 , and the pneumatic nozzle clamp 7 is arranged in the middle of the base 1 .

[0023] By adopting the above technical solution, after the injection molding is completed, the robotic arm moves the loading rack to the top of the finished product. After receiving the signal, the pneumatic nozzle clamp 7 clamps the head of the finished product and takes it out of the injection molding machine, realizing the dual functions of loading and taking out, reducing the process and improving work efficiency.

[0024] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
