[0003] The patent with the publication number of CN216100185U discloses a small injection mold with a hot runner structure, including a mold body with a cavity. The bottom of the mold body is provided with an installation groove. The bottom of the installation groove is provided with an unclosed annular runner. The annular runner is provided with a plurality of blind hole inclined runners extending upwards at intervals along the circumferential direction. Each blind hole inclined runner is close to the cavity wall of the cavity and is arranged in a surrounding layout. The blind hole inclined runner at the starting end of the annular runner is communicated with a transverse water inlet hole, and the blind hole inclined runner at the end of the annular runner is communicated with a transverse water outlet hole; a sealing block is arranged in the installation groove, and the top of the sealing block is provided with a sealing surface which is hermetically connected with the bottom of the installation groove to seal the bottom of the annular runner. In the small injection mold designed by this patent, a hot runner structure is directly processed on the periphery of the cavity of the mold to quickly cool the formed product, thereby shortening the processing cycle of the product, accelerating the cooling and blanking after the product is formed, and effectively improving the processing efficiency of the product.

[0004] As shown in the above technology, when a common hot runner injection mold is working, the gating system of the injection mold generally adopts multi-tube uniform pouring. Multiple groups of pouring tubes need to be regularly maintained to ensure stable and uniform blanking. The disassembly and assembly of the common device are relatively complex and inconvenient to operate. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides an injection mold with a hot runner diversion and interconnection structure, which solves the problems that multiple groups of pouring tubes need to be regularly maintained to ensure stable and uniform blanking, and the disassembly and assembly of the common device are relatively complex and inconvenient to operate.

[0015] Preferably, a baffle is slidably connected to one side of the stabilizing plate, and a plug plate column is movably connected to one side of the baffle.

[0016] The present utility model provides an injection mold with a hot runner diversion and interconnection structure. Compared with the prior art, the following beneficial effects are achieved:

[0017] (1) For the injection mold with the hot runner diversion and interconnection structure, by using the setting of the pouring assembly, the device can quickly disassemble the dovetail plate and the injection pipe as a whole from the surface of the track plate through the movement of the dovetail plate in the dovetail groove. And during installation, only need to insert the plug plate column into the circular groove, and then move the baffle to make one side of the baffle closely fit the surface of the plug plate column, which is convenient for operation, and solves the problem that multiple pouring pipes need to be regularly maintained to ensure stable and uniform feeding, and the disassembly and assembly of ordinary devices are relatively complex and inconvenient for operation.

[0030] The moving module 6 has a limiting groove 7 opened on its surface, a top groove 8 opened at the bottom of the moving module 6, and a feeding port 9 communicated with the top of the moving module 6;

[0031] The pouring assembly 10, the two sides of the pouring assembly 10 are fixedly connected to the inner wall of the top groove 8. The pouring assembly 10 is used for uniformly feeding molten plastic. With the setting of the pouring assembly 10, the device can quickly disassemble the dovetail plate 103 and the injection pipe 106 as a whole from the surface of the track plate 101 by the movement of the dovetail plate 103 in the dovetail groove 102. And during installation, only need to insert the plug-in plate column 108 into the circular groove 109, and then move the baffle 107 to make one side of the baffle 107 closely fit the surface of the plug-in plate column 108, which is convenient for operation, and solves the problem that multiple pouring pipes need to be regularly maintained to ensure stable and uniform feeding, and the disassembly and assembly of ordinary devices are relatively complex and inconvenient to operate.

[0032] Embodiment 2, the main difference from Embodiment 1 is: an injection mold with a hot runner diversion and interconnection structure. The heating assembly 5 includes a threaded sleeve 51 fixedly connected to one side of the inner wall of the working groove 2. The inner wall of the threaded sleeve 51 is threadedly connected with a screw rod 52. The bottom end of the screw rod 52 is provided with an anti-slip handle. A positioning bottom plate 53 is movably sleeved on the surface of the screw rod 52 by threads. A heating rod 54 is fixedly connected to the top of the positioning bottom plate 53. The heating rod 54 is a resistance wire or an electric heating belt, which generates heat through current. The pouring assembly 10 includes a track plate 101 fixedly connected to the inner wall of the top groove 8. A removal groove is opened in the middle of the track plate 101, and the size of the removal groove is larger than the width of the dovetail plate 103. A circular groove 109 is opened on the surface of the track plate 101, and the inner wall of the circular groove 109 is adapted to the plug-in plate column 108. A dovetail groove 102 is opened on the surface of the track plate 101, and a dovetail plate 103 is movably connected to the inner wall of the dovetail groove 102. A stabilizing plate 104 is fixedly connected to one side of the dovetail plate 103. An installation sleeve plate 105 is rotatably connected to one side of the stabilizing plate 104. An injection pipe 106 is fixedly connected to the bottom of the installation sleeve plate 105. A baffle 107 is slidably connected to one side of the stabilizing plate 104. A plug-in plate column 108 is movably connected to one side of the baffle 107. Anti-slip patterns are provided on the surfaces of the baffle 107 and the plug-in plate column 108. One side of the plug-in plate column 108 is not connected to the stabilizing plate 104 in any form. Only during installation, it relies on itself to squeeze the baffle 107 on the surface of the stabilizing plate 104 to realize the limiting and fixing of the stabilizing plate 104. With the setting of the heating assembly 5, when disassembling the heating rod 54, only need to rotate the screw rod 52 to separate the screw rod 52 from the threaded sleeve 51, and the positioning bottom plate 53 and the heating rod 54 can be directly taken off as a whole. Through the setting of the interconnection flow channel 11, the interconnected flow channel design can better balance the pressure at each injection point, ensure the uniform flow of molten plastic in the mold, and reduce the risk of uneven filling.

[0033] The bottom end of the feed inlet 9 is communicated with the injection pipe 106 through a stainless steel hose.

[0034] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] During operation, turn on the heating rod 54 in the heating tank 3. The inner wall of the inter - communication flow channel 11 is heated. Move the moving module 6 downward along the limit column 4. After it fits with the top of the static module 1, the injection pipe 106 enters the inside of the static module 1. Pour molten plastic through the feed inlet 9. The molten plastic is injected into the inter - communication flow channel 11 through the injection pipe 106. The molten plastic enters the inner wall of the static module 1 through the inter - communication flow channel 11. After cooling and forming, move the moving module 6 upward to take out the formed product in the static module 1. When maintaining the heating rod 54, rotate the screw rod 52 to separate the screw rod 52 from the threaded sleeve 51, and then move the positioning bottom plate 53 and the heating rod 54 downward as a whole to take them out from the bottom of the static module 1. When maintaining and disassembling the injection pipe 106, move the baffle 107 on the surface of the stabilizing plate 104, pull out the plug - in plate column 108 externally to separate the plug - in plate column 108 from the circular groove 109, and then move the dovetail plate 103 in the dovetail groove 102 to remove the dovetail plate 103 and the whole injection pipe 106 from the moving module 6, and then maintain and restore it. When the device is completely used up, restore the device.
