[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0018] Example: Figures 1-5 As shown, this embodiment proposes a mold blank with cooling clearance and return pin positioning, including: a mold base plate 1, a cooling component 2 for cooling the mold is bolted to the top of the mold base plate 1, and a positioning component 3 for positioning is provided on the cooling component 2. The cooling assembly 2 includes a module 201 bolted to the top of the mold base plate 1. The module 201 has a water pipe groove 202. An ejector plate 203 is bolted to the top of the mold base plate 1, and a rear horizontal guide frame 204 and a front horizontal guide frame 205 are also bolted to the top of the mold base plate 1. The water pipe groove 202 on the module 201 can be connected to a cooling water pipe. When the cooling water flows in the water pipe, it carries away the heat generated by the mold during operation, thereby cooling the mold. The ejector plate 203 plays a crucial role in the mold opening and closing and in ejecting the product; it can accurately eject the molded product from the mold according to the set actions.

[0019] like Figures 2-5 As shown, the positioning component 3 includes a guide sleeve 301 embedded in the guide hole of the rear transverse frame 204, and guide posts 302 at the bottom of the front transverse frame 205. Four sets of guide posts 302 correspond to the positions of the guide sleeve 301. A return pin 303 is provided at the bottom of the front transverse frame 205, extending downwards and passing through the rear transverse frame 204. During the mold opening and closing process, the front transverse frame 205 and the rear transverse frame 204 move relative to each other. The guide posts 302 perform precise linear movement within the guide sleeve 301, providing precise guidance for the relative movement of the front transverse frame 205 and the rear transverse frame 204, ensuring that they do not deviate during movement. When the mold opens, the return pin 303 functions as a positioning and limiting element, ensuring that the various parts of the mold separate according to predetermined positions and sequences. When the mold closes, the return pin 303 guides the various parts of the mold to accurately return to their original positions.

[0020] like Figures 2-5As shown, the front horizontal guide frame 205 is located on top of the rear horizontal guide frame 204, and a guide frame is formed between the opposite faces of the rear horizontal guide frame 204 and the front horizontal guide frame 205. When the mold is opened and closed, the front horizontal guide frame 205 moves relative to the rear horizontal guide frame 204 along a certain trajectory, ensuring that the various parts of the mold can be accurately matched, reducing errors caused by inaccurate movement of parts, thereby improving the molding quality of the product and making the produced product dimensions more accurate.

[0021] like Figures 2-5 As shown, there are two sets of modules 201 symmetrically arranged on both sides of the ejector plate 203. The inner contour of the guide sleeve 301 is adapted to the outer contour of the guide post 302, and the guide post 302 slides along the inside of the guide sleeve 301. During mold opening and closing operations, the inner contour of the guide sleeve 301 matches the outer contour of the guide pillar 302, allowing the guide pillar 302 to slide stably and precisely along the interior of the guide sleeve 301. The sliding of the guide pillar 302 within the guide sleeve 301 provides precise guidance for the relative movement of the front horizontal slide frame 205 and the rear horizontal slide frame 204, ensuring they move in a predetermined direction and trajectory. During mold closing, the sliding of the guide pillar 302 within the guide sleeve 301 also guides the front horizontal slide frame 205 and the rear horizontal slide frame 204 to accurately reset, ensuring that the front horizontal slide frame 205 and the rear horizontal slide frame 204 do not shift during movement. This reduces errors caused by inaccurate component movement, thereby improving the molding quality of the product and making the produced product dimensions more accurate. It also helps to improve the service life and stability of the mold.

[0022] like Figures 2-5 As shown, the top of the front horizontal frame 205 is provided with a front mold cable groove 4 and a nozzle 5, and the front mold cable groove 4 is located on one side of the nozzle 5. During the mold injection process, the molten plastic raw material will be injected into the mold cavity through the nozzle 5. The front mold cable groove 4 centrally collects various cables in the front mold area, avoiding messy cable distribution and preventing cables from getting tangled or stuck during mold opening and closing.

[0023] like Figures 3-5 As shown, the other end of the return pin 303 is located in the mounting groove on the ejector plate 203, and the return pin 303 is connected to the ejector plate 203 by bolts. The return pin 303 serves to limit and guide the movement trajectory of the ejector plate 203, ensuring that the ejector plate 203 moves smoothly in a specific direction. During mold closing, the return pin 303 can also guide the ejector plate 203 to accurately reset.

[0024] like Figures 2-5As shown, there are four sets of return pins 303, symmetrically arranged at the bottom of the rear horizontal guide frame 204 and inside the guide post 302. When the mold opens and closes, the rear horizontal guide frame 204 moves linearly under the guidance of the guide post 302, and the return pins 303 move together with the rear horizontal guide frame 204. During the mold movement, the guiding force on the rear horizontal guide frame 204 is uniform, effectively avoiding the offset phenomenon caused by uneven force, and further reducing the error caused by inaccurate component movement.

[0025] Working Principle: This utility model provides a mold blank with cooling venting and return pin positioning. The specific usage steps are as follows: Step 1: During the mold opening and closing process, the front horizontal slide frame 205 and the rear horizontal slide frame 204 will move relative to each other. The guide post 302 performs precise linear movement within the guide sleeve 301, providing precise guidance for the relative movement of the front horizontal slide frame 205 and the rear horizontal slide frame 204, ensuring that they do not deviate during movement. When the mold opens, the return pin 303 can play a positioning and limiting role, ensuring that the various parts of the mold separate according to the predetermined position and sequence; when the mold closes, the return pin 303... The pin 303 can guide the various parts of the mold to accurately reset; Step 2: The water pipe groove 202 opened on the module 201 can be connected to the cooling water pipe. When the cooling water flows in the water pipe, it will carry away the heat generated by the mold during operation, thereby cooling the mold. The ejector plate 203 plays a key role in the mold opening and closing and ejecting the product. It can accurately eject the molded product from the mold according to the set action, reduce the error caused by inaccurate movement of parts, thereby improving the molding quality of the product, making the produced product size more accurate, and also helping to improve the service life and stability of the mold.

[0026] All technical features in this embodiment can be freely combined according to actual needs.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
