[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0030] Example 1
[0031] Reference Figures 1 to 4 As an embodiment of the utility model, an injection mold ox-horn glue injection insert mechanism 10 is provided, including a first insert 11 and a second insert 12 embedded in a mold core 30, the first insert 11 is located outside the contour of the mold core 30, the second insert 12 is located inside the contour of the mold core 30 and constitutes a local part of the mold core 30, a first flow channel 13 is formed on the joint surface of the first insert 11 and the mold core 30, one end of the first flow channel 13 is connected to a glue injection runner 22 opened in the mold core 30, a second flow channel 14 is opened in the second insert 12, the second flow channel 14 is connected to the other end of the flow channel, and the other end of the second flow channel 14 is a glue inlet 141 for the product.
[0032] Compared with the prior art, the overall insert is divided into the first insert 11 and the second insert 12. The first insert 11 is located outside the mold core 30 and is not a component of the mold core 30, while the second insert 12 is located inside the mold core 30 and constitutes a partial part of the mold core 30. In this way, the splicing line of the first insert 11 will not contact the appearance of the product, which can effectively avoid the appearance of insert clamping marks or flash caused by the splicing line on the molded product, thereby ensuring product quality and facilitating the processing of the horn glue inlet flow channel.
[0033] Specifically, the mold core 30 is provided with a through hole 31 and a blind hole 32, the second insert 12 is plugged into the through hole 31 and constitutes a partial part of the mold core 30, and the first insert 11 is plugged into the blind hole 32. The top of the first insert 11 is provided with a first arc groove 111, and the bottom of the blind hole 32 is provided with a second arc groove 321. After the second insert 12 is plugged into the blind hole 32, the first arc groove 111 and the second arc groove 321 enclose the first flow channel 13. In order to facilitate the uniform flow rate of the molten glue in the first flow channel 13, the cross-sectional area of the first flow channel 13 gradually decreases from one end connected to the glue injection runner 22 to the other end. In order to ensure a certain glue injection speed of the glue inlet 141 and avoid glue shortage, the cross-sectional area of the second flow channel 14 gradually decreases from one end connected to the first flow channel 13 to the other end and is set in a conical shape.
[0034] Furthermore, in this embodiment, the top width of the first insert 11 is smaller than the bottom width, and the through hole 31 is adapted to the first insert 11. The top width of the second insert 12 is smaller than the bottom width, and the blind hole 32 is adapted to the second insert 12. The above structure can achieve a limiting effect on the installation of the first insert 11 and the second insert 12.
[0035] As a variable embodiment, a limiting structure may be provided to limit the installation positions of the first insert 11 and the second insert 12 . In this case, the specific structures of the first insert 11 and the second insert 12 may not be limited.
[0036] Furthermore, the second insert 12 includes a first splicing block 121 and a second splicing block 122, a first splicing groove 123 is provided on the side of the first splicing block 121, and a second splicing groove 124 is provided on the side of the second splicing block 122. After the first splicing block 121 and the second splicing block 122 are combined, the first splicing groove 123 and the second splicing groove 124 enclose the second flow channel 14. Since the second flow channel 14 is an arc-shaped channel, it is difficult to directly process it. With the above-mentioned structural form, the groove-shaped structure is easy to process, and the second flow channel 14 can be formed after splicing.
[0037] Furthermore, the side wall of the through hole 31 is connected to the side wall of the blind hole 32, and the first insert 11 and the second insert 12 can be assembled into an overall insert. The side wall of the through hole 31 is connected to the side wall of the blind hole 32, and during installation, the first insert 11 and the second insert 12 can be assembled into an overall insert externally, and then the overall insert can be directly installed, thereby improving installation efficiency.
[0038] Example 2
[0039] Reference Figures 1 to 4 , as an injection mold provided by an embodiment of the utility model, includes the injection mold ox-horn glue insert mechanism 10 described in Example 1.
[0040] Specifically, the injection mold further includes a mold body 20 and a mold core 30. The mold core 30 is arranged on the mold body 20. The mold core 30 is provided with a through hole 31 and a blind hole 32. The second insert 12 is plugged into the through hole 31 and constitutes a partial part of the mold core 30. The first insert 11 is plugged into the blind hole 32. The injection runner 22 is arranged on the mold body 20. Compared with the prior art, the overall insert is split into the first insert 11 and the second insert 12. The first insert 11 is located outside the mold core 30 contour and is not a component of the mold core 30. The second insert 12 is located inside the mold core 30 contour and constitutes a partial part of the mold core 30. In this way, the splicing line of the first insert 11 will not contact the appearance surface of the product, so that the insert clamping line mark or the flash generated by the splicing line on the molded product can be effectively avoided, thereby ensuring product quality and facilitating the processing of the horn injection runner.
[0041] Furthermore, the mold body 20 is provided with a plurality of mold cores 30, each mold core 30 is provided with an injection mold horn glue insert mechanism 10, and the mold body 20 is provided with a glue injection port 21, which is connected to each glue injection runner 22.
