Plug processing injection molding device

Abstract

This utility model relates to the field of plug processing technology and discloses a plug processing injection molding device, including a worktable and a bottom mold. By controlling the handle to rotate the rotating rod, and further benefiting from the limiting of the slide rail and slide block, while the position of the bottom mold changes due to the rotation of the rotating rod, it is ensured that the bottom mold is always in a horizontal state. By rotating the handle, the bottom mold and plug can be sent in or moved out from under the top mold, which can prevent the operator from pinching their fingers when picking up the plug. By setting a buffer spring, it plays a supporting role between the bottom mold and the top mold and the support. The plug components are embedded into the bottom mold and hot melt plastic particles are injected. Further, the hydraulic rod is controlled to drop the top mold to form the plug. When the hydraulic rod is controlled to separate the bottom mold and the top mold, the buffer spring pushes out the support, thereby leaving a gap between the tail of the plug and the bottom mold, which facilitates the picking up of the plug.

Description

Technical Field

[0001] This utility model relates to the field of plug processing technology, specifically a plug processing injection molding device. Background Technology

[0002] The plug processing injection molding device is a piece of equipment used to produce plug connector housings. Molten plastic is injected into a mold, and the mold is opened for injection molding, which can realize the mass production of plugs and significantly improve production efficiency.

[0003] Chinese patent CN221392059U discloses an injection molding apparatus for plug manufacturing, comprising an injection molding machine body, a sealing plate, and a mold. The injection molding machine body has an internal movable groove, inside which a push rod is fixedly connected. A movable plate is fixedly connected to the top of the push rod, and the movable plate has an internal mounting groove for mounting the mold. This invention facilitates mold installation through the cooperation between a fixing ring and a fixing block. After installation, the fixing block prevents mold shaking during operation. Through the cooperation between the push rod and the movable plate, the position of the injection port on the mold can be adjusted according to the height of the injection rod after changing molds of different heights, ensuring that the height of the injection port on the mold is consistent with the height of the injection rod.

[0004] The above-mentioned device has the effect of adjusting the position of the injection port. However, the existing device requires picking up the plug injection molded product between the upper and lower molds after injection molding is completed, which poses a risk of the mold pinching the hand. Moreover, after the plug is injection molded, it is tightly embedded in the mold, which greatly increases the difficulty of picking up the plug injection molded product. Therefore, there is a need to provide a plug processing injection molding device. Utility Model Content

[0005] The purpose of this invention is to provide a plug injection molding device to solve the problems of existing devices having the risk of mold clamping and the inconvenience of picking up the finished plug injection molded products.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plug processing injection molding device, comprising a worktable and a bottom mold, a hydraulic rod fixedly installed on the upper part of the worktable, a top mold fixedly installed at the output end of the hydraulic rod, and a mold feeding mechanism provided on the worktable; the mold feeding mechanism includes two rotating seats, which are respectively fixedly installed on the worktable and the bottom mold, and a rotating rod is rotatably installed between the two rotating seats, a handle is fixedly installed on one side of the rotating rod, two sliding rods are fixedly installed side by side on the lower part of the bottom mold, two support seats are fixedly installed side by side on the upper part of the worktable, and two slide rails are fixedly installed side by side in the middle of the worktable, two pulleys are slidably installed on the upper and lower sides of the two slide rails, and a sliding seat is fixedly installed between the two pulleys.

[0007] Preferably, both supports are located below the top mold, and the bottom mold is adapted to the two supports.

[0008] Preferably, the slide block has two slots arranged side by side, and the two slide rods are respectively embedded and slidably installed in the two slots.

[0009] Preferably, the bottom mold and the top mold are provided with a disassembly mechanism. The disassembly mechanism includes two supports, which are slidably installed on the bottom mold and the top mold respectively. Four limiting posts are fixedly installed on one side of each support. Four stops are fixedly installed on one side of each bottom mold and the top mold. Buffer springs are fixedly installed between the stops and the limiting posts.

[0010] Preferably, both the bottom mold and the top mold are provided with arc-shaped grooves, and the limiting posts are slidably installed through the bottom mold and the top mold.

[0011] Preferably, a baffle is fixedly installed at one end of both the limiting post and the stop, and the limiting post and the stop are located on the same vertical plane.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This injection molding device for plug processing uses a handle to rotate a lever. It further benefits from the limiting of the slide rail and slide block. While the position of the bottom mold changes as the lever rotates, it ensures that the bottom mold is always in a horizontal state. In use, the bottom mold and plug can be sent in or moved out from under the top mold by rotating the handle. This can bring the bottom mold closer to the operator and prevent the operator from pinching their fingers when picking up the plug.

[0014] 2) This plug injection molding device uses a buffer spring to support the bottom mold, top mold and support. In use, plug components are embedded into the bottom mold and hot melt plastic granules are injected. The hydraulic rod is then controlled to drop the top mold to form the plug. When the hydraulic rod is controlled to separate the bottom mold and the top mold, the buffer spring pushes the support out, thus leaving a gap between the plug tail and the bottom mold for easy plug pickup.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-5 A plug injection molding device includes a worktable 1 and a bottom mold 2. A hydraulic rod 3 is fixedly installed on the upper part of the worktable 1, and a top mold 4 is fixedly installed at the output end of the hydraulic rod 3. A mold feeding mechanism 5 is provided on the worktable 1. The mold feeding mechanism 5 includes two rotating seats 501, which are respectively fixedly installed on the worktable 1 and the bottom mold 2. A rotating rod 502 is rotatably installed between the two rotating seats 501. A handle 503 is fixedly installed on one side of the rotating rod 502. Two sliding rods 504 are fixedly installed side by side on the lower part of the bottom mold 2. Two support seats 505 are fixedly installed side by side on the upper part of the worktable 1. Two slide rails 506 are fixedly installed side by side in the middle of the worktable 1. Two pulleys 507 are slidably installed on the upper and lower sides of the two slide rails 506. A sliding seat 508 is fixedly installed between the two pulleys 507.

[0024] See Figure 2 and Figure 3 Furthermore, it is found that both support bases 505 are located below the top mold 4, the bottom mold 2 is adapted to the two support bases 505, and two slots are opened side by side on the slide base 508, and the two slide rods 504 are respectively embedded and slidably installed in the two slots.

[0025] Specifically, by controlling the handle 503, the rotating rod 502 is rotated around the rotating base 501. One end of the rotating rod 502 is connected to the worktable 1 through the rotating base 501, and the other end of the rotating rod 502 is connected to the bottom mold 2 through the rotating base 501. When the rotating rod 502 changes from horizontal to vertical, the bottom mold 2 will be supported. When the bottom mold 2 moves, the sliding rod 504 moves inside the sliding base 508, and the sliding base 508 moves on the slide rail 506 through the pulley 507, which can ensure that the bottom mold 2 is always in a horizontal state when moving.

[0026] Example 2

[0027] Combination Figure 1 and Figure 4 The bottom mold 2 and the top mold 4 are provided with a disassembly mechanism 6. The disassembly mechanism 6 includes two supports 601, which are slidably installed on the bottom mold 2 and the top mold 4 respectively. Four limiting posts 602 are fixedly installed on one side of the support 601. Four stops 603 are fixedly installed on one side of both the bottom mold 2 and the top mold 4. A buffer spring 604 is fixedly installed between the stop 603 and the limiting posts 602.

[0028] See Figure 4 Furthermore, based on Embodiment 1, both the bottom mold 2 and the top mold 4 are provided with arc-shaped grooves, and the limiting posts 602 are slidably installed on the bottom mold 2 and the top mold 4. One end of the limiting post 602 and the stop 603 is fixedly installed with a baffle plate, and the limiting post 602 and the stop 603 are located on the same vertical plane.

[0029] Specifically, when the hydraulic rod 3 separates the bottom mold 2 from the top mold 4, the support 601 will move outward along the bottom mold 2 and the top mold 4 under the action of the buffer spring 604. In use, the plug components are embedded into the bottom mold 2 and hot melt plastic granules are injected. The hydraulic rod 3 is then controlled to drop the top mold 4 to form the plug. After the hydraulic rod 3 separates the bottom mold 2 from the top mold 4, the buffer spring 604 pushes the support 601 out, thereby leaving a gap between the tail of the plug and the bottom mold 2 to facilitate the picking up of the plug.

[0030] In actual operation, the handle 503 is controlled to make the rotating rod 502 rotate around the rotating seat 501. One end of the rotating rod 502 is connected to the worktable 1 through the rotating seat 501, and the other end of the rotating rod 502 is connected to the bottom mold 2 through the rotating seat 501. When the rotating rod 502 turns from horizontal to vertical, the bottom mold 2 will be supported. When the bottom mold 2 moves, the sliding rod 504 moves inside the sliding seat 508, and the sliding seat 508 moves on the slide rail 506 through the pulley 507, which can ensure that the bottom mold 2 is always in a horizontal state when it moves.

[0031] When the hydraulic rod 3 separates the bottom mold 2 from the top mold 4, the support 601 will move outward along the bottom mold 2 and the top mold 4 under the action of the buffer spring 604. In use, the plug components are embedded into the bottom mold 2 and hot melt plastic granules are injected. The hydraulic rod 3 is then controlled to drop the top mold 4 to form the plug. After the hydraulic rod 3 separates the bottom mold 2 from the top mold 4, the buffer spring 604 pushes the support 601 out, thereby leaving a gap between the tail of the plug and the bottom mold 2 to facilitate the picking up of the plug.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
