DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] Please refer to Figures 1-3 , the present invention provides a technical solution: an injection mold with a seal, including an upper mold body 101, a lower mold body 106 and a lower template 103. The top of the upper mold body 101 is fixedly provided with an upper template 100. An injection port 108 is opened inside the upper template 100. During use, the injection port 108 communicates with the cavity. A gate ring 107 is fixedly provided on the upper template 100. Cavities are opened inside both the upper mold body 101 and the lower mold body 106. A sealing mechanism is provided on the upper template 100. The sealing mechanism includes a seal and two sets of connecting components. The seal includes a circular plate 200 and a rubber sealing ring 201. The rubber sealing ring 201 is fixed outside the circular plate 200. During use, the rubber sealing ring 201 can achieve a sealing effect. The bottoms of the circular plate 200 and the rubber sealing ring 201 both penetrate into the inside of the gate ring 107. The connecting component includes an extension plate 211. One end of the extension plate 211 is fixed on the circular plate 200. During use, the extension plate 211 is fixed to the circular plate 200. The other end of the extension plate 211 is fixedly provided with a vertical plate 215. During use, the vertical plate 215 connects the extension plate 211 and a magnet 212 together. A magnet 212 is fixedly provided at the bottom of the vertical plate 215. Two sets of iron blocks 214 are provided on the top of the upper template 100. The magnet 212 and the iron block 214 are connected by adsorption. During use, the seal can be conveniently disassembled and assembled through adsorption connection. A side plate 213 is fixedly provided on the side of the iron block 214. The side plate 213 and the upper template 100 are fixedly connected by screws.

[0023] In summary, insert the seal into the inside of the gate ring 107. At this time, the bottoms of the circular plate 200 and the rubber sealing ring 201 on the gate ring 107 are inserted into the inside of the gate ring 107. At this time, the rubber sealing ring 201 makes the circular plate 200 and the gate ring 107 have a sealing effect. Then, make the bottom of the magnet 212 contact the upper surface of the iron block 214. At this time, the magnet 212 and the iron block 214 are adsorbed together. At this time, the seal can be installed, and external impurities can be prevented from entering the inside of the gate ring 107 and the injection port 108. When in use, operate according to the reverse principle above to pull out the seal. Unscrew the screws on the side plate 213 to remove the iron block 214, and tighten the screws to install the iron block 214.

[0024] Embodiment 2

[0025] Please refer to Figures 1 to 4 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, and the difference is as follows.

[0026] In this embodiment, preferably, two groups of fixing members 102 are provided on both side surfaces of the lower template 103. When in use, the fixing member 102 is a U-shaped block, and the fixing device is used through the U-shaped block to fix it on the injection molding machine, and then the lower template 103 is fixed on the injection molding machine. Two sets of disassembly and assembly mechanisms are provided between the fixing member 102 and the lower template 103. The disassembly and assembly mechanism includes a fixing block 300. The fixing block 300 is fixed on the side surface of the lower template 103, and the fixing block 300 and the lower template 103 are fixedly connected by bolts. When in use, through the disassembly and assembly mechanism, it is convenient to separately replace the damaged fixing member 102 when the fixing member 102 is damaged during use, which is convenient for subsequent use of the injection mold.

[0027] In this embodiment, preferably, a bearing plate 105 is fixedly provided at the bottom of the lower die body 106, and two spacer plates 104 are fixedly provided at the bottom of the bearing plate 105.

[0028] In this embodiment, preferably, the lower template 103 is fixed at the bottom of the spacer plate 104.

[0029] In summary, when the fixing member 102 is damaged, the bolt on the fixing block 300 can be unscrewed to remove the fixing member 102, and then a new fixing member 102 can be taken out and replaced by operating according to the reverse principle described above.

[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
