Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, and in particular to a mold structure. Background Technology

[0002] Mold structure refers to the overall structure of a mold, which combines various functional parts in a certain way and with a certain relationship to achieve a specific molding process. SEB frying pans are made of highly thermally conductive materials, such as copper and aluminum, which are installed at the bottom of the pan to enhance the heat conduction efficiency of the pan. This allows heat to be transferred to the entire bottom of the pan more quickly and evenly, avoiding local overheating and improving the cooking effect. The accessories installed at the bottom of the SEB frying pan are formed by stamping with a mold.

[0003] A search revealed Chinese Patent Publication No. CN111844562A, which discloses a mold structure comprising: a lower fixed plate disposed on a horizontal plane; a male mold plate disposed above the lower fixed plate; a male mold core disposed on the male mold plate; a female mold plate disposed above the male mold plate; a female mold core disposed on the female mold plate; an upper fixed plate disposed above the female mold plate; a support plate disposed below the male mold plate; and a cavity. The cavity is located in the middle of the connection between the male mold core and the female mold core. The mold structure of this invention not only reduces the forming thickness of the mold cavity, but also improves the processing efficiency and yield of the product. However, in the existing mold structure, for some parts with extremely high requirements for dimensional accuracy and surface quality, the material will undergo elastic deformation and plastic deformation during the stamping process. The elastic recovery of the material will cause the dimensions of the stamped part to deviate from the dimensions of the mold, making it difficult to accurately control the stamping process. This will affect the assembly accuracy of subsequent parts and thus affect the overall performance of the frying pan. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mold structure, which aims to improve the existing technology for some parts with extremely high requirements for dimensional accuracy and surface quality. During the stamping process, the material will undergo elastic deformation and plastic deformation. The elastic recovery of the material will cause the dimensions of the stamped part to deviate from the dimensions of the mold. The stamping process is difficult to control precisely, which will affect the assembly accuracy of subsequent parts and thus affect the overall performance of the frying pan.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mold structure, including a support plate, a positioning plate fixedly connected to the bottom adjacent side of the support plate, an ejector pin fixedly connected to the top of the outer wall of the positioning plate, fixing columns fixedly connected to the front and rear sides of the outer wall of the positioning plate, an elastic reset member fixedly connected to the outer wall of the fixing column, a connecting column slidably connected to the middle of the inner wall of the positioning plate, a lower template fixedly connected to the top of the outer walls of the two support plates, a plurality of square grooves opened in the middle of the inner wall of the lower template, a circular groove opened in the middle of the inner wall of each of the square grooves, a stamping accessory fixedly connected to the middle of the inner wall of the circular groove, an upper template slidably connected to the top of the outer wall of the lower template, a feed channel opened in the middle of the inner wall of the upper template, a cooling water channel opened in the middle of the outer wall of the lower template, a base fixedly connected to the bottom of the outer wall of the support plate, a plurality of square holes opened in the middle of the inner wall of the base, a plurality of fixing holes opened in the outer wall of the base, and a buffer mechanism fixedly connected to the left and right sides of the outer wall of the support plate, the buffer mechanism being used to reduce and support the mold.

[0041] Reference Figure 1 , Figure 2 and Figure 5The buffer mechanism 2 includes a connecting plate 201. Two connecting plates 201 are fixedly connected to the left and right sides of the outer wall of the support plate 1. Adjusting rod 1 202 is rotatably connected to the bottom front and rear sides of the two connecting plates 201. The other end of the adjusting rod 1 202 is rotatably connected to a fixing block 203. A sliding rod 204 is slidably connected to the middle of the inner wall of the fixing block 203. A buffer spring 205 is fixedly connected to the outer wall of the sliding rod 204.

[0043] Reference Figure 1 , Figure 2 and Figure 3 Limiting plates 18 are fixedly connected to the left and right sides of the outer wall of the telescopic spring 17. A buffer pad 21 is fixedly connected to the top of the outer wall of the upper template 12. Bolts 22 are threadedly connected to the four corners of the top of the buffer pad 21.

[0044] Specifically, the telescopic spring 17 has its telescopic range limited by the limiting plate 18 to prevent excessive compression or stretching, ensuring the spring works safely and effectively and providing stable elastic support for the mold. During the mold opening and closing process, the spring assists the upward ejection mechanism and provides cushioning, while the limiting plate 18 ensures the spring works normally. A buffer pad 21 is fixed to the top of the upper template 12 to absorb impact force and protect the template and connected components. The buffer pad 21 is fixed by bolts 22 for easy installation and replacement.

[0045] Working principle: The positioning plate 3 is fixed to the bottom adjacent side of the support plate 1. Its function is to provide a foundation for positioning and support of the mold. During the working process of the mold, the positioning plate 3 helps to ensure the position accuracy of the ejector pin 4 connected to it, avoiding the impact of positional deviation on the accuracy of subsequent holes. The ejector pin 4 is fixed to the top of the outer wall of the positioning plate 3 and is usually used to eject the molded workpiece from the mold. After the mold completes one molding operation, the ejector pin 4 will move upward to eject the molded product from the mold. In the injection mold, the product will fit tightly with the mold cavity after molding. The ejector pin 4 can separate the product from the mold for easy removal. The fixing post 5 is connected to the front and rear sides of the outer wall of the positioning plate 3, providing a secure anchor for the elastic reset part 6. The elastic reset member 6 provides restoring force. After the ejector pin 4 completes its ejection action, the elastic reset member 6 can pull the ejector pin 4 back to its initial position for the next molding operation. After ejecting the product, the elastic reset member 6 uses its own elasticity to reset the ejector pin 4, preparing it for the next ejection action. The connecting column 7 slides in the middle of the inner wall of the positioning plate 3, serving to connect different mold components and guide the mold movement. During the mold opening and closing process, the sliding of the connecting column 7 ensures the accuracy of the relative movement trajectory between mold components, ensuring the stability and reliability of the mold movement. The lower mold plate 8 is supported by two support plates 1. The multiple square grooves 9 and circular grooves 10 on the lower mold plate 8 are the cavity structure of the mold, used to accommodate... The shape of the stamping part 11 and the circular groove 10 is designed according to the shape and structure of the product to be formed. The stamping part 11 is installed in the middle of the inner wall of the circular groove 10. During the stamping process, the stamping part 11 cooperates with the upper template 12 to process the material placed in the mold. The upper template 12 is slidably connected to the top of the outer wall of the lower template 8. The inner wall of the upper template 12 has an inlet channel 13, which is a channel for introducing the processing material. During the stamping process, the upper template 12 moves downward and cooperates with the lower template 8 to stamp the material input by the inlet channel 13 to achieve the forming operation. The relative movement of the upper template 12 and the lower template 8 is the key to mold forming, and the fitting accuracy between the two directly affects the quality of the product. Cooling channels 14 are located in the middle of the outer wall of the lower mold plate 8. During the molding process, especially in thermoforming, the coolant flows in the cooling channels 14, carrying away the heat in the mold and allowing the product to cool and solidify quickly. In the injection mold, the molten material injected into the mold is formed inside the mold. The coolant circulates through the cooling channels 14, carrying away the heat and accelerating the cooling speed of the product, thereby improving production efficiency and product quality. The base 15 is fixed to the bottom of the outer wall of the support plate 1, providing a stable support foundation for the entire mold. The inner wall of the base 15 has multiple square holes 16 and fixing holes 23. These holes are used to install and fix the mold, making it easy to connect with other equipment and ensuring the stability and safety of the mold during operation.

[0046] Two connecting plates 201 are fixedly connected to the left and right sides of the outer wall of the support plate 1. Their main function is to provide connection and support points for the adjusting rod 202. The connecting plates 201 connect the support plate 1 with other adjusting components, so that the whole structure forms a buffer mechanism 2, and can act as a medium for force and motion transmission, ensuring the integrity and stability of the structure. The adjusting rod 202 is rotatably connected to the bottom front and rear sides of the connecting plate 201 respectively, and its other end is rotatably connected to the fixed block 203. This rotary connection allows the adjusting rod 202 to rotate within a certain angle range, which is used to reduce the force and angle during the spatial stamping of the entire mechanism. When external force is applied to the adjusting rod 202, due to the characteristics of the rotary connection, it flexibly changes its position and angle, thereby driving the connected parts to move. The slide rod 204 is slidably connected to the middle of the inner wall of the fixed block 203. This sliding connection allows the slide rod 204 to move linearly within the fixed block 203. During the operation of the mold or mechanical equipment, forces and displacements in various directions will occur. The sliding of the slide rod 204 can adapt to these changes, ensuring that the entire structure can maintain a certain degree of freedom when subjected to force. For flexibility, the buffer spring 205 is fixed to the outer wall of the slide rod 204, serving as a buffer and shock absorber. When impact or external force acts on the mechanism, the buffer spring 205 undergoes elastic deformation, absorbing some energy and preventing it from being directly transmitted to other components, protecting the entire mechanism from excessive impact. It also makes the movement smoother. During mold opening and closing and equipment operation, if impact or vibration occurs, the buffer spring 205 will absorb energy through expansion and contraction, making the movement of the entire mechanism smoother and more stable. Adjusting rod two 206: One end of adjusting rod two 206 is fixedly connected to the bottom of the outer wall of the fixed block 203, and the other end is rotatably connected to the fixed plate 207. Adjusting rod two 206 works in conjunction with adjusting rod one 202, using rotation and length adjustment to adapt to different working requirements, allowing the mechanism to better adapt to different working conditions. The fixed plate 207, as the support and fixing part of the entire mechanism, provides a support point for the rotatable connection of adjusting rod two 206, fixing the mechanism to the corresponding equipment and frame, ensuring the stability of the entire structure.
