[0024] Example:

[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0026] A catheter seat forming mold which is easy to disassemble and assemble comprises an upper mold base 1 and a lower mold base 2, a feed plate 3 is fixedly mounted on the top of the upper mold base 1, an upper mold 4 is fixedly mounted on the bottom of the upper mold base 1, a base 5 is fixedly mounted on the bottom of the lower mold base 2, guide seats 6 are fixedly mounted on the left and right ends of the top of the lower mold base 2, a lower mold 7 is clamped inside the lower mold base 2 and located between two groups of guide seats 6, a plurality of groups of injection molded products 8 are arranged on the inner side of the lower mold 7, demolding seats 9 are slidably connected to the inner sides of the two groups of guide seats 6, and a plurality of groups of demolding rods 10 are fixedly mounted on the left and right ends of the bottom of the upper mold base 1.

[0027] First, guide rods 201 are fixedly installed at the four corners on the top of the lower mold base 2, and the four corners on the bottom of the upper mold base 1 are slidably connected to the guide rods 201 through connecting sleeves 202. When the upper mold base 1 and the lower mold base 2 are closed, the guide rods 201 are inserted into the inner side of the connecting sleeves 202 for positioning and guiding, ensuring that the upper mold base 1 and the lower mold base 2 can be accurately molded.

[0028] Furthermore, multiple groups of injection holes 301 are opened inside the feed plate 3, and multiple groups of molding cavities 401 are opened on the inner sides of the upper mold 4 and the lower mold 7, and the multiple groups of injection holes 301 are connected with the inner sides of the molding cavities 401. When producing the catheter seat, the raw material is injected through the injection holes 301 and then introduced into the molding cavity 401 for injection molding.

[0029] Then, a mounting groove 402 adapted for use with the upper mold 4 is opened on the inner side of the upper mold base 1, and the front and rear ends of the upper mold 4 are fixedly connected to the upper mold base 1 by a first mounting bolt 403. When installing the upper mold 4, the upper mold 4 is placed into the inner side of the mounting groove 402, and the upper mold 4 is fixed by the first mounting bolt 403 to complete the installation. When replacing the upper mold 4, it only needs to unscrew the first mounting bolt 403 to remove it.

[0030] Secondly, the front and rear ends of the two groups of guide seats 6 are fixedly connected to the lower mold base 2 by the second fixing bolts 601, and the interiors of the two groups of demolding seats 9 are fixedly installed with multiple groups of mold cores 901, and the multiple groups of mold cores 901 extend to the interior of the injection molded product 8. The multiple groups of mold cores 901 are fixedly connected to the guide seats 6 by the third fixing bolts 902. When installing the lower mold 7, after the lower mold 7 is placed on the top of the lower mold base 2, the two groups of guide seats 6 are placed on the left and right sides of the lower mold 7 respectively, and then the guide seats 6 are installed and fixed by the second fixing bolts 601, so that the lower mold 7 is clamped and fixed between the two groups of guide seats 6. When replacing the lower mold 7, the demolding seat 9 can be removed after being fixed. During injection molding production, the multiple groups of mold cores 901 are located on the inner side of the molding cavity 401, so that the interior of the molded catheter seat is hollow. At the same time, after replacing the mold, the mold core 901 can be disassembled by the third fixing bolts 902, and the corresponding mold core 901 can be replaced.

[0031] Finally, the front and rear ends of the two groups of demolding seats 9 are fixedly connected with sliding columns 903, and the two groups of sliding columns 903 are slidably connected to the guide seats 6 through guide grooves 904. The interiors of the left and right ends of the lower mold base 2 are provided with through grooves 1001 adapted to the demolding rods 10. The interiors of the two groups of demolding seats 9 are provided with multiple groups of oblique slots 1002 adapted to the demolding rods 10. During injection molding, when the upper mold base 1 and the lower mold base 2 are closed, the multiple groups of demolding rods 10 are sequentially inserted into the oblique slots 1002 and the inner sides of the through grooves 1001, so that the two groups The mold core 901 on the opposite side of the demolding seat 9 is inserted into the interior of the molding cavity 401 to cooperate with injection molding. After the injection molded product 8 is produced, the upper mold seat 1 is separated from the lower mold seat 2. As the separation demolding rod 10 of the upper mold seat 1 moves upward, under the guidance of the sliding column 903 and the guide groove 904, the two groups of demolding seats 9 are driven to slide on the inner side of the guide seat 6, so that the two groups of demolding seats 9 move relative to each other to move the mold core 901 out of the inner side of the molding cavity 401, thereby automatically completing the demolding, which does not affect the disassembly and assembly of the lower mold 7 while improving the production efficiency.

[0032] In this embodiment, the implementation scenario is specifically as follows: when installing the upper mold 4, after placing the upper mold 4 into the inner side of the installation groove 402, the upper mold 4 can be fixed by the first installation bolt 403 to complete the installation. When replacing the upper mold 4, it is only necessary to unscrew the first installation bolt 403 to remove it. When installing the lower mold 7, after placing the lower mold 7 on the top of the lower mold base 2, the two groups of guide seats 6 are respectively placed on the left and right sides of the lower mold 7, and then the guide seats 6 are installed and fixed by the second fixing bolts 601, so that the lower mold 7 is clamped and fixed between the two groups of guide seats 6. When replacing the lower mold 7, the demolding seat 9 can be removed after the fixation. When performing injection molding production, when the upper mold base 1 and the lower mold base 2 are closed, multiple groups of demolding rods 10 is inserted into the inner side of the inclined slot 1002 and the through slot 1001 in sequence, so that the mold core 901 on the opposite side of the two groups of demolding seats 9 is inserted into the interior of the molding cavity 401 for injection molding. After the injection molded product 8 is produced, the upper mold base 1 is separated from the lower mold base 2. As the separation demolding rod 10 of the upper mold base 1 moves upward, under the guidance of the sliding column 903 and the guide groove 904, the two groups of demolding seats 9 are driven to slide on the inner side of the guide seat 6, so that the two groups of demolding seats 9 move relative to each other to move the mold core 901 out of the inner side of the molding cavity 401, thereby automatically completing the demolding, while not affecting the disassembly and assembly of the lower mold 7, the production efficiency is improved, and the entire operation process is simple and convenient. Compared with the existing catheter seat molding mold, the utility model improves the convenience of mold disassembly and assembly through design, and at the same time improves the production efficiency.
