[0024] See also Figures 1 to 3 In order to address the technical problem that improper handling of the splicing gap during the mold splicing process caused by the split mold design affects the installation process and use process of the split mold, the utility model provides a split mold splicing structure; the split mold splicing structure of the utility model uses a sealing layer to seal the splicing gap of the splicing mold, thereby increasing the splicing connection strength, and a positioning sleeve to adjust the splicing gap, thereby improving the mold installation efficiency.

[0025] To achieve the above and other related purposes, please refer to Figures 1 to 3 The present invention provides a split mold splicing structure, including a first splicing module 100, a second splicing module 200, a sealing layer 300 and a positioning sleeve 400, wherein the first splicing module 100 is provided with a mold cavity partially used for product production; similarly, the second splicing module 200 is provided with a mold cavity partially used for product production, and the second splicing module 200 is spliced ​​and connected to the first splicing module 100. When the first splicing module 100 and the second splicing module 200 are spliced ​​and connected, the mold cavities on their respective splicing modules are combined to form a complete mold cavity. The shape of the mold cavity is not limited and is designed according to the shape of the product to be manufactured. The splicing connection method of the first splicing module 100 and the second splicing module 200 is not limited and can be any suitable type of method that meets the connection strength of the first splicing module 100 and the second splicing module 200 and meets the use requirements, such as flange bolt connection, clamp connection or welding connection.

[0026] A joint gap is formed at the joint between the first and second joint modules 100, 200; the joint gap is located at the joint surface between the first and second joint modules 100, 200. A sealing layer 300 is disposed within the joint gap. The sealing layer 300 adhesively connects the first and second joint modules 100, 200, sealing and filling the joint gap. This prevents air leakage from the joint gap caused by vacuuming during mold production, thereby ensuring mold performance and product quality. The adhesive connection of the sealing layer 300 also increases the connection strength between the first and second joint modules 100, 200, further ensuring the stability of the joint structure.

[0027] Positioning holes for assembly positioning are respectively provided on the first splicing module 100 and the second splicing module 200. The positioning holes are positioned and matched with the positioning sleeves 400 so that the positioning sleeves 400 are sandwiched between the first splicing module 100 and the second splicing module 200. When the first splicing module 100 and the second splicing module 200 are installed, rapid installation and positioning are achieved. At least part of the positioning sleeves 400 is located in the splicing gap, that is, part of the positioning sleeves 400 is located in the sealing layer 300 between the first splicing module 100 and the second splicing module 200. By replacing different types of positioning sleeves 400, the length of the positioning sleeves 400 located in the splicing gap is changed, thereby adjusting the width of the splicing gap. This helps to ensure that the size of the molded product meets the design requirements, ensures the stability and integrity of the product during the product molding process, improves the appearance quality of the product, and can extend the service life of the mold and reduce maintenance costs.

During the manufacturing process of the first splicing module 100, the first positioning reinforcement plate 120 is first installed and positioned, and then the first split mold 110 is injection-molded; the first positioning reinforcement plate 120 can evenly distribute the pressure borne by the mold during the injection molding process of the first split mold 110 to prevent the mold from deformation or damage. At the same time, the first positioning reinforcement plate 120 has a positioning hole structure for being engaged with the positioning sleeve 400, thereby facilitating the splicing and positioning of the first splicing module 100 and the second splicing module 200 and improving assembly efficiency.

[0029] Furthermore, the manufacturing process and structure of the second splicing module 200 are similar to those of the first splicing module 100. Specifically, the second splicing module 200 includes a second split mold 210 and a second positioning reinforcement plate 220. The second split mold 210 is an injection molding structure. The second positioning reinforcement plate 220 is located in the second split mold 210 and is used to distribute the pressure during the injection molding process of the second split mold 210. The second positioning reinforcement plate 220 is engaged with the other end of the positioning sleeve 400, thereby realizing the splicing positioning of the first splicing module 100 and the second splicing module 200 and improving the assembly efficiency.

[0030] See also Figure 2 and Figure 3 In one embodiment of the split mold splicing structure of the present invention, the positioning sleeve 400 includes a first embedded portion 410, a second embedded portion 420 and a clamping ring 430, wherein the first embedded portion 410, the second embedded portion 420 and the clamping ring 430 are an integrated structure, and the clamping ring 430 is located between the first embedded portion 410 and the second embedded portion 420, and is located on the outside of the first embedded portion 410 and the second embedded portion 420. When installed and positioned, the first embedded portion 410 is embedded and connected to the first splicing module 100; the second embedded portion 420 is embedded and connected to the second splicing module 200, and the clamping ring 430 is clamped between the first splicing module 100 and the second splicing module 200, and is located in the splicing gap. By changing the model of the positioning sleeve 400, that is, changing the axial size of the clamping ring 430, the size of the splicing gap can be adjusted to achieve adjustment of the splicing gap. Specifically, in this embodiment, the first embedded portion 410 is embedded in the positioning hole connected to the first positioning reinforcement plate 120; the second embedded portion 420 is embedded in the positioning hole connected to the second positioning reinforcement plate 220, and the clamping ring 430 is clamped between the first embedded portion 410 and the second embedded portion 420 to form a splicing gap, and the positioning sleeve 400 not only realizes positioning cooperation, but also the positioning sleeve 400 is used to seal the sealing layer 300 to prevent leakage of the sealant.

[0031] See also Figure 2In one embodiment of the split mold splicing structure of the present invention, the sealing layer 300 includes a sealing strip 310 and a sealing layer 320. The sealing strip 310 is arranged at the edge of the splicing gap away from the cavity; that is, the sealing strip 310 is clamped and installed at the outer edge of the first split mold 110 and the second split mold 210 to prevent leakage of the sealant. The sealing layer 320 is coated in the splicing gap between the sealing strip 310 and the cavity. The sealing layer 320 is used to bond the first split mold 110 and the second split mold 210. The sealing layer 320 is formed by coating the sealant; the sealant is applied after the positioning sleeve 400 is positioned, so as to ensure that the vacuum of the split splicing mold during use will not cause air leakage at the splicing gap; the type of sealant can be acrylic sealant, so as to achieve rapid curing and high-strength bonding.

[0032] See also Figure 1 In one embodiment of the split mold splicing structure of the present invention, the first splicing module 100 and the second splicing module 200 are provided with a skin layer 600, which is located in the mold cavity.

The prefabricated surface skin 620 is formed on the positive mold and adapted to the shape of the mold cavity on the negative mold.

The locking assembly 500 sequentially penetrates and connects the first splicing module 100, the positioning sleeve 400 and the second splicing module 200, thereby locking and fixing the first splicing module 100 and the second splicing module 200. Specifically, in this embodiment, the locking assembly 500 includes a locking bolt 510, a locking nut 520, a first gasket 530 and a second gasket 540.
