Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically relating to an injection mold with adjustable gating channel direction. Background Technology

[0002] Injection molds are tools for producing plastic products and are also important equipment for giving plastic products a complete structure and precise dimensions. They inject molten plastic under high pressure into the mold cavity, and after cooling and solidification, the molded product is obtained. They play a vital role in the production of plastic products. In ordinary molds, the nozzle is locked to the fixed mold panel by screws, and it is impossible to rotate the nozzle or adjust the injection channel, which makes it inconvenient to perform injection molding on different products.

[0003] Existing technology CN207206972U discloses an injection mold with adjustable gating runner direction, including a locating ring lock, a nozzle, a head, a fixed mold panel, a ring portion, a bottom surface, a mold core, a multi-pass runner, two sub-runners, cavities, an end face, a mold core, a recessed runner opening, and a second through hole. The locating ring lock is attached to the fixed mold panel around the nozzle head, and the bottom surface of the inner edge of the ring portion presses against the outer edge of the nozzle head to restrict the axial movement of the nozzle. The mold core corresponds to the mold core combination of another mold (lower mold), making the multi-pass runner, two sub-runners, and each cavity a closed channel, which can guide the injection fluid to flow along each runner. Each cavity (22a, 22b) is a product with a different shape. The end face of the nozzle tube is flush with or protrudes from the surface of the mold core where the sub-runners are set. The multiple sub-runners are two (sub-runners 2) located in a straight line. 3a, 23b), the recessed runner openings (4211a, 4211b, 4211c) of the multi-pass runner are three channels with an angle of 90° between them, while the rotation angle positioning grooves are four channels with an angle of 90° between them. When the multi-pass runner 422 (three-way runner) is rotated for positioning, the recessed runner openings (4211a, 4211b) of the multi-pass runner 422 (three-way runner) are simultaneously connected to the branch runners (23a, 23b), and the other recessed runner opening is blocked by the wall of the second through hole of the mold core. When the nozzle rotates 90 degrees clockwise, the recessed runner opening of the multi-pass runner 422 (three-way runner) is only connected to the branch runner, and the other two recessed runner openings (4211a, 4211b) are blocked by the wall of the second through hole of the mold core 20, thus facilitating injection molding of different products.

[0004] In normal use, the positioning ring locks onto the fixed mold panel around the nozzle head, and the bottom surface of the inner edge of the ring presses against the outer edge of the nozzle head to restrict the axial movement of the nozzle. The existing technology is time-consuming and laborious in the process of disassembling and installing the nozzle, making it inconvenient to replace the nozzle. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the positioning ring is locked to the fixed mold panel on the periphery of the nozzle head, and the bottom surface of the inner edge of the ring abuts against the outer edge of the nozzle head to restrict the axial movement of the nozzle. In the existing technology, the disassembly and installation of the nozzle is time-consuming and laborious, making it inconvenient to replace the nozzle.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides an injection mold with adjustable gating channel direction, including a lower mold and a structural device; the structural device includes an upper mold, a positioning pin, a mold core, a nozzle, a fixed block, a cylinder, a first spring, a moving component, and an adjusting component. The positioning pin is fixedly installed on one side of the lower mold. The upper mold is detachably connected to the positioning pin and located on the side of the positioning pin closer to the lower mold. The cylinder is fixedly connected to the upper mold and located on the side of the upper mold away from the lower mold. The moving component is connected to the cylinder. The fixed block is slidably connected to the cylinder and connected to the moving component. One end of the first spring is connected to the fixed block, and the other end of the first spring is connected to the cylinder. The nozzle is detachably connected to the upper mold and detachably connected to the fixed block. The adjusting component is connected to the upper mold. The mold core is detachably connected to the lower mold and detachably connected to the nozzle.

[0008] The adjustment component includes an adjustment block and a driving component. The adjustment block is slidably connected to the upper mold and is located on the side of the upper mold near the nozzle. The driving component is connected to the upper mold and to the adjustment block.

[0009] The driving component includes a driving block and a power component. The driving block is fixedly connected to the adjusting block and slidably connected to the upper mold. The power component is connected to the upper mold and slidably connected to the driving block.

[0010] The power component includes a second spring and a frame. The frame is fixedly connected to the drive block and slidably connected to the upper mold. One end of the second spring is connected to the upper mold, and the other end of the second spring is connected to the drive block.

The movable block is fixedly connected to the movable rod and is located on the side of the movable rod away from the fixed block.

[0012] This utility model discloses an injection mold with an adjustable pouring channel direction. When adjusting the pouring channel, the nozzle is rotated. After rotation to the correct position, the second spring drives the drive block to move. The drive block drives the adjustment block to move on the upper mold, so that the adjustment block abuts against the positioning hole of the nozzle, positioning the rotation angle of the nozzle. When replacing the nozzle, the nozzle is placed on the mounting cavity of the upper mold, and the moving block is released. The first spring drives the fixed block and the moving rod to move on the cylinder. At the same time, the fixed block abuts against the fixing groove of the nozzle, thereby installing the nozzle on the upper mold. Conversely, disassembly is performed, thus facilitating the replacement of the nozzle. Attached Figure Description
