Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a mold structure for achieving stable production. Background Technology

[0002] In modern electronic equipment and power transmission systems, plugs are key components connecting power sources and equipment, and their quality and performance directly affect the normal operation and safety of the equipment. Plug molds, as the core tool for plug production, play a decisive role in the dimensional accuracy, appearance quality, and production efficiency of plugs; however, existing mold structures still encounter some problems in actual use.

[0003] For example, patent application number CN202322672222.5 discloses a wire harness plug injection mold, including a fixed mold base plate and a moving mold base plate. A rectangular fixed module is fixedly installed under the fixed mold base plate, and an injection nozzle extending downward through the fixed module is fixedly installed on the fixed mold base plate. Two parallel side plates are fixedly installed on the upper side of the moving mold base plate, and a support plate is fixedly installed on the side plates. A rectangular moving module is fixedly installed on the support plate. This design is beneficial for improving production efficiency. Existing mold structures are relatively simple. During use, since the copper pins are punched, there is a certain tolerance range. However, the height dimensions of the ejector pins and inserts are fixed within the mold. If the length dimensions of the plug copper pins cannot be guaranteed to be consistent in each batch, then the dimensions of the injection molded products will be defective.

[0004] To address the aforementioned problems, a mold structure for achieving stable production is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a mold structure that enables stable production. By using this device, the problem of existing mold structures being relatively simple and having a certain tolerance range during use is solved. Since the copper feet are punched, the height dimensions of the ejector pins and inserts are fixed within the mold. If the length dimensions of the copper feet of the plug cannot be guaranteed to be consistent in each batch, then the dimensions of the injection molded products will have defects.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold structure for stable production, comprising a fixed mold and a movable mold disposed on top of the fixed mold, wherein a water inlet pipe is fixedly connected to one side of the fixed mold, and two sets of the water inlet pipe are provided, and a return pipe is fixedly connected to one end of the water inlet pipe, a heat dissipation vent is provided on one side of the fixed mold, and an electric push rod is fixedly connected inside the heat dissipation vent, wherein multiple sets of the electric push rod are provided, and a connecting plate is fixedly connected to the bottom of the movable mold.

[0007] Preferably, the mold has a placement cavity inside, the return pipe is located inside the placement cavity, and a heat-conducting sheet is fixedly connected inside the placement cavity.

[0008] By adopting the above-mentioned structural design, a highly efficient active cooling system is constructed by opening a placement cavity inside the fixed mold and embedding the return pipe inside it, along with a heat-conducting plate. The placement cavity provides a stable installation space for the return pipe and the heat-conducting plate, ensuring that their positions are accurate and do not interfere with other core components of the mold.

[0009] Preferably, the heat-conducting sheet is matched with the connecting plate, and the output end of the electric push rod is fixedly connected to a sliding plate.

[0010] The design employing the above-described structure, with precise matching between the heat-conducting plate and the connecting plate, ensures highly efficient heat transfer. The connecting plate, serving as the connecting carrier between the moving mold and the insert body, directly contacts the high-temperature injection molten metal. The heat-conducting plate's close fit minimizes heat transfer loss, rapidly channeling heat into the cooling system and further optimizing the cooling effect.

[0011] Preferably, the sliding plate is slidably connected inside the fixed mold, and a spring rod is fixedly connected to the top of the sliding plate.

[0012] The design of the above structure, with the sliding connection between the sliding plate and the fixed mold, limits the movement trajectory of the sliding plate, ensuring that it can only move in a fixed direction under the drive of the electric push rod, avoiding lateral deviation, and providing stable support for the subsequent vertical ejection of the ejector body.

[0013] Preferably, the spring rod is provided in two sets, and a connecting block is fixedly connected to the top of the spring rod.

[0014] The above-described structure connects the two sets of spring rods to the ejector pin body as a whole via a connecting block, achieving uniform force transmission. The connecting block also prevents localized stress concentration caused by direct contact between the spring rods and the ejector pin body, protecting the structural integrity of both the ejector pin body and the spring rods, and extending their service life.

[0015] Preferably, the top of the connecting block is fixedly connected to an ejector pin body, and the ejector pin body is slidably connected inside the fixed mold.

[0016] The design of the above structure, with the connecting block and the ejector body fixedly connected, allows the ejector body to move synchronously with the connecting block, ensuring a smooth and precise ejection action.

[0017] Preferably, the bottom of the connecting plate is fixedly connected to an insert body, which matches the ejector pin body.

[0018] With the above-mentioned structural design, the insert body is fixed at the bottom of the connecting plate, so that the insert body can open and close synchronously with the moving mold, ensuring that the insert body and the fixed mold cavity are precisely connected during the injection molding process, forming a complete injection space, and ensuring that the molded shape of the plastic part meets the design requirements.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This application, through the setting of electric push rod, sliding plate, ejector pin body and spring rod, realizes the effect of convenient injection molding of different copper feet by the staff, improves the use effect, and solves the problem that the existing mold structure is relatively simple. In the process of use, since the plug copper feet are punched, there is a certain tolerance range. However, the height of the ejector pin and insert is fixed in the mold. If the length of the plug copper feet cannot be guaranteed to be consistent in each batch, then the dimensional problems of the injection molded products will exist.

[0021] 2. This application, through the setting of water inlet pipe, return pipe and heat conduction plate, enables workers to quickly and easily remove the workpiece, improves work efficiency, and solves the problem that the existing mold structure often achieves cooling through natural cooling, which is inefficient and cannot quickly demold.

[0028] 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.

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0030] Combination Figures 1-3 A mold structure for achieving stable production includes a fixed mold 1 and a movable mold 2 disposed on top of the fixed mold 1. A water inlet pipe 11 is fixedly connected to one side of the fixed mold 1. Two sets of water inlet pipes 11 are provided. A return pipe 111 is fixedly connected to one end of the water inlet pipe 11. A heat dissipation vent 12 is opened on one side of the fixed mold 1. An electric push rod 121 is fixedly connected inside the heat dissipation vent 12. Multiple sets of electric push rods 121 are provided. A connecting plate 21 is fixedly connected to the bottom of the movable mold 2.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the issue of existing mold structures being relatively simple, and the fact that the plug copper pins are punched and have a certain tolerance range, while the height of the ejector pins and inserts is fixed within the mold, if the length of the plug copper pins cannot be guaranteed to be consistent from batch to batch, then the dimensional defects of the injection-molded products will occur. This embodiment discloses the following technical solution, specifically as follows: Figures 1-5As shown, the output end of the electric push rod 121 is fixedly connected to a sliding plate 122, which is slidably connected inside the fixed mold 1. A spring rod 123 is fixedly connected to the top of the sliding plate 122. Two sets of spring rods 123 are provided. A connecting block 124 is fixedly connected to the top of the spring rod 123, and an ejector pin body 125 is fixedly connected to the top of the connecting block 124. The ejector pin body 125 is slidably connected inside the fixed mold 1. An insert body 211 is fixedly connected to the bottom of the connecting plate 21, and the insert body 211 matches the ejector pin body 125. In use, the plug copper pin is placed on top of the fixed mold 1, and then the moving mold 2 can be started. After the moving mold 2 moves down, the ejector pin body 125 can be moved through the top of the moving mold 2. The injection port injects into the interior of the moving mold 2. When the copper plug pins are placed inside the fixed mold 1, the spring rod 123 and the ejector pin body 125 inside the fixed mold 1 ensure that the copper plug pins are at the same height. The spring rod 123 lifts the copper plug pins, ensuring that they are at the same height even if the copper plug pins are not the same size, thus ensuring stable injection molding production. After molding is completed, the moving mold 2 can be started, and then the electric push rod 121 can be started. The electric push rod 121 drives the sliding plate 122 to move, which in turn moves the ejector pin body 125. The ejector pin body 125 pushes the plug pin out from inside the fixed mold 1, which realizes the effect of convenient injection molding of different copper plug pins by the operator and improves the use effect.

[0034] Example 2:

[0035] To address the issue that existing mold structures often rely on natural cooling, which is inefficient and hinders rapid demolding, this embodiment discloses the following technical solution, specifically as follows: Figure 2 and Figure 4 As shown, the fixed mold 1 has a placement cavity 112 inside, and the return pipe 111 is located inside the placement cavity 112. A heat-conducting plate 113 is also fixedly connected inside the placement cavity 112. The heat-conducting plate 113 matches the connecting plate 21. After injection molding is completed, the operator can pass water into the return pipe 111 through the water pipe 11 on one side of the fixed mold 1. Under the action of the heat-conducting plate 113 inside the placement cavity 112, the heat generated by injection molding is absorbed, and the return pipe 111 can also play a cooling role, which further improves the demolding efficiency of the fixed mold 1 and enables the operator to quickly remove the workpiece, thereby improving work efficiency.
