Ejector pin assemblies, as an indispensable and important component in injection molds, play a crucial role in the demolding process of plastic products. Their performance directly affects product quality and production efficiency, and consequently, the smooth operation of the entire production process and the economic benefits of the enterprise.

[0003] However, the existing ejector pin assembly has limitations in its original design. The lack of a positioning structure between the ejector pin holder and the ejector pin cap means that it can only be used for single-pin operation and cannot meet the diverse chip processing needs.

[0004] Therefore, those skilled in the art have provided a novel ejector pin assembly structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel ejector pin assembly structure. This structure overcomes the limitations of using a single ejector pin in the D510 ejector pin assembly by adding positioning grooves and positioning pins to the ejector pin assembly base, ejector pin seat, and ejector pin cap, thereby achieving precise positioning and use of multiple ejector pins. This meets the processing needs of chips of various sizes, expands the application range of the Canon D510 chip mounting equipment, and improves the versatility of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A novel ejector pin assembly structure includes a base, an ejector pin seat, and an ejector pin cap. A base positioning pin is fixedly connected to one side of the base, and a base positioning groove is formed on one side of the base. An ejector pin seat positioning pin is fixedly connected to one side of the ejector pin seat, and multiple ejector pin cap positioning grooves are formed on one end face of the ejector pin cap.

[0008] Through the above technical solution, this structure solves the limitation of using a single pin in the D510 pin assembly by adding positioning grooves and positioning pins to the pin assembly base, pin seat, and pin cap, respectively. It realizes the precise positioning and use of multiple pins, thereby meeting the processing needs of chips of various sizes, expanding the application range of the Canon D510 chip mounting equipment, and improving the versatility of the equipment.

[0009] Furthermore, a plurality of first through holes are provided on the outer side of the ejector pin seat;

[0010] The above technical solutions can increase the heat dissipation area of ​​the ejector pin holder, which helps to quickly dissipate the heat generated by the ejector pin during high-temperature operation, avoid heat accumulation that could damage the ejector pin and surrounding components, and improve the thermal stability and service life of the ejector pin assembly.

[0011] Furthermore, a plurality of second through holes are provided in the middle of one end face of the ejector pin cap;

[0012] The above technical solution can enhance the heat dissipation performance of the ejector cap, form a good ventilation and heat dissipation channel with the first through hole on the ejector seat, and further optimize the heat dissipation effect of the entire ejector assembly.

[0013] Furthermore, the base positioning pin on the base is located inside the ejector cap positioning groove on the ejector cap;

[0014] Through the above technical solution, the base positioning pin on the base and the ejector cap positioning groove on the ejector cap are used together to achieve precise positioning between the base and the ejector cap. This can effectively prevent the ejector cap from shifting or rotating during installation and use, ensuring the assembly accuracy and stability of the ejector assembly, thereby ensuring the precise positioning and reliable contact of the ejector pin during chip processing, and improving processing quality and efficiency.

[0015] Furthermore, the ejector seat positioning pin on the ejector seat is located inside the base positioning groove on the base;

[0016] Through the above technical solution, the positioning pin on the ejector pin holder and the positioning groove on the base are used together to achieve precise positioning between the ejector pin holder and the base. This ensures that the ejector pin holder is installed in the base accurately and avoids loosening or displacement of the ejector pin holder during high temperature or long-term use. This ensures the overall stability and reliability of the ejector pin assembly and improves the precision and consistency of chip processing.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Reference Figure 1-3 The present invention provides a specific embodiment of a novel ejector assembly structure, comprising a base 1, an ejector seat 4, and an ejector cap 7. A base positioning pin 2 is fixedly connected to one side of the base 1, and a base positioning groove 3 is provided on one side of the base 1. A ejector seat positioning pin 5 is fixedly connected to one side of the ejector seat 4, and a plurality of ejector cap positioning grooves 8 are provided on one end face of the ejector cap 7.

[0026] This structure solves the limitation of using a single pin in the D510 pin assembly by adding positioning grooves and positioning pins to the pin assembly base 1, pin seat 4 and pin cap 7 respectively, and realizes the precise positioning and use of multiple pins, thereby meeting the processing needs of chips of various sizes, expanding the application range of the Canon D510 chip mounting equipment and improving the versatility of the equipment.

[0027] Multiple first through holes 6 are provided on the outer side of the ejector seat 4, which increases the heat dissipation area of ​​the ejector seat 4 and helps to quickly dissipate the heat generated by the ejector during high-temperature operation, avoiding heat accumulation that could damage the ejector and surrounding components, and improving the thermal stability and service life of the ejector assembly. Multiple second through holes 9 are provided in the middle of one end face of the ejector cap 7, which enhances the heat dissipation performance of the ejector cap 7 and forms a good ventilation and heat dissipation channel with the first through holes 6 on the ejector seat 4, further optimizing the heat dissipation effect of the entire ejector assembly. The base positioning pin 2 on the base 1 is located inside the ejector cap positioning groove 8 on the ejector cap 7. The base positioning pin 2 on the base 1 and the ejector cap positioning groove 8 on the ejector cap 7 work together to realize the connection between the base 1 and the ejector cap 7. Precise positioning effectively prevents the ejector cap 7 from shifting or rotating during installation and use, ensuring the assembly accuracy and stability of the ejector assembly. This guarantees the precise positioning and reliable contact of the ejector pins during chip processing, improving processing quality and efficiency. The ejector seat positioning pin 5 on the ejector seat 4 is located inside the base positioning groove 3 on the base 1. The ejector seat positioning pin 5 on the ejector seat 4 works in conjunction with the base positioning groove 3 on the base 1 to achieve precise positioning between the ejector seat 4 and the base 1. This ensures that the ejector seat 4 is installed accurately on the base 1, preventing the ejector seat 4 from loosening or shifting during high-temperature or long-term use. This ensures the overall stability and reliability of the ejector assembly, improving the accuracy and consistency of chip processing.

[0028] Working Principle: In use, the ejector pin seat 4 first slides into the base 1, and its upper ejector pin seat positioning pin 5 then slides into the base positioning groove 3, achieving initial positioning. Subsequently, the ejector pin cap 7 is fitted onto the outside of the base 1, and its ejector pin cap positioning groove 8 cooperates with the base positioning pin 2 for further precise positioning. Through the dual positioning mechanism of the ejector pin seat positioning pin 5 and the base positioning groove 3, and the base positioning pin 2 and the ejector pin cap positioning groove 8, the precise positioning of multiple ejector pins is ensured, avoiding the problem of machining accuracy and reliability being affected by positional shift or loosening of the ejector pins during high-temperature and long-term use. This allows the ejector pin assembly to work stably and reliably, thereby ensuring the quality and efficiency of chip processing.
