Description

Technical Field

[0001] This utility model relates to the field of rectifier mesh technology, specifically a rectifier mesh mold. Background Technology

[0002] Rectifier mesh molds are key tools used in manufacturing rectifier meshes. Their design must balance precision and durability. The mold typically consists of components such as a front mold, a rear mold, and slides. High-hardness alloy steel is used to ensure molding stability, and high-precision replication of complex mesh structures is achieved through precision machining. The mold design needs to optimize the flow channels to reduce material waste, while rounded corners and reinforcing ribs are set to improve the strength of the product. In the fields of electronics and power, the high-efficiency production capacity of rectifier mesh molds can significantly reduce manufacturing costs and meet the needs of large-scale industrialization.

[0003] In existing technologies, rectifier mesh molding has significant limitations. The most prominent problem is that it cannot produce multiple products at once. Traditional mold designs are simple in structure, and only a single rectifier mesh can be produced during injection molding or die casting. This not only leads to long production cycles and limited output per unit time, making it difficult to meet the needs of large-scale production, but also increases mold wear and failure risk due to frequent mold opening and closing operations, raising production costs, causing fluctuations in product quality, and affecting the consistency and stability of rectifier mesh performance. Therefore, we need a rectifier mesh mold. Utility Model Content

[0004] The purpose of this utility model is to provide a rectifier mesh mold to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rectifier mesh mold, including an injection port, an upper mold fixedly connected to the bottom of the injection port, a cooling water pipe provided on one side of the upper mold, a forming component provided at the bottom of the upper mold, a sliding rod fixedly connected to the bottom of the upper mold, a lower mold slidably connected to the outer wall of the sliding rod, a locking component fixedly connected to one side of the upper mold, the forming component including a channel opening located inside the upper mold, a flow channel provided at the bottom of the upper mold, sprue material provided inside the flow channel, and a mold cavity provided at the bottom of the upper mold, with a workpiece placed inside the mold cavity.

[0006] Preferably, the channel opening and the flow channel form a connected structure, and multiple channel openings are distributed at equal intervals on the flow channel.

[0007] Preferably, the flow channel is connected to the mold cavity through the channel opening, and the mold cavity is located on both sides of the flow channel and the channel opening.

[0008] Preferably, the engaging assembly includes a first fixed shell, which is fixed to one side of the upper mold. A support frame is fixedly connected to the inner wall of the first fixed shell. A protrusion is fixedly connected to the bottom of the support frame. A latch is engaged with the outer wall of the protrusion. A fixing block is fixedly connected to one side of the latch. A return spring is provided at the bottom of the fixing block. A connecting frame is fixedly connected to the bottom of the return spring. A second fixed shell is fixedly connected to the bottom of the connecting frame.

[0009] Preferably, the support frame forms an engaging structure with a protrusion and a latch, and the outer diameter of the protrusion matches the inner diameter of the latch, and the outer wall of the protrusion fits against the inner wall of the latch.

[0010] Preferably, the fixing block is elastically connected to the connecting frame via a reset spring, and the reset spring is disposed between the fixing block and the connecting frame.

[0011] Preferably, two return springs are provided on one side of the protrusion, and the two return springs are symmetrically arranged about the vertical line of the protrusion as the axis of symmetry.

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

[0013] In the scheme of this application:

[0014] 1. To address the problem that existing molds cannot produce multiple parts at once, this application sets up a system where, after the mold is closed, molding liquid is injected from the injection port. The liquid flows out through the channel and smoothly enters the mold cavity along the runner, filling it completely. This ensures uniform filling of the molding liquid, resulting in a complete and stable structure of the molded workpiece, reducing the production of defective products, and improving production efficiency. This mold can accurately mold sprue material and workpieces, facilitating subsequent separation and processing, reducing production costs, and bringing better economic benefits and product competitiveness to enterprises.

[0015] 2. To address the mold locking stability issue in existing technologies, this application proposes a design where, when the mold closes, the upper mold drives the sliding rod, the first fixed shell, and other components to move in an orderly manner. Automatic locking is achieved through the clever cooperation between the protrusion and the latch. The protrusion presses against the latch, stretching the return spring. Subsequently, the latch engages with the protrusion to complete the locking process. This process is smooth and requires no additional complex operations. After engagement, the return spring can precisely reset the latch, improving assembly efficiency, ensuring the stability and reliability of the locking mechanism, effectively preventing accidental loosening of the mold during subsequent use, ensuring product molding quality, saving costs for enterprises, and improving production efficiency.

[0023] 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.

[0024] This utility model embodiment provides a rectifier mesh mold, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes an injection port 1, an upper mold 2 fixedly connected to the bottom of the injection port 1, a cooling water pipe 3 provided on one side of the upper mold 2, a molding component 4 provided at the bottom of the upper mold 2, a sliding rod 5 fixedly connected to the bottom of the upper mold 2, a lower mold 6 slidably connected to the outer wall of the sliding rod 5, and a locking component 7 fixedly connected to one side of the upper mold 2. The molding component 4 includes a channel opening 401, which is located inside the upper mold 2. A flow channel 402 is provided at the bottom of the upper mold 2. The mold 2 has a sprue 403 inside and a mold cavity 404 at the bottom. The mold cavity 404 contains a workpiece 405. After closing, the molding liquid is injected into the injection port 1, allowing the molding liquid to flow out from the channel port 401 and enter the mold cavity 404 along the flow channel 402, filling the mold cavity 404. This allows the boxed parts mold to be formed inside the upper mold 2 and the lower mold 6, finally obtaining the sprue 403 and the workpiece 405.

[0025] Furthermore, such as Figure 3 and Figure 4 As shown, the channel opening 401 and the flow channel 402 form a connected structure, and multiple channel openings 401 are distributed at equal intervals on the flow channel 402. Through the multiple through openings 401, the molding liquid can flow out along multiple channel openings, accelerating the entry of the molding liquid into the mold cavity 404.

[0026] Furthermore, such as Figure 3 and Figure 4 As shown, the flow channel 402 is connected to the mold cavity 404 through the channel opening 401, and the mold cavity 404 is located on both sides of the flow channel 402 and the channel opening 401. Through the flow channel 402 and the channel opening 401, and the channel opening 401 is connected to the mold cavity 404 through the flow channel 402, the channel opening 401 can transport the molding liquid to the mold cavity 404 through the flow channel 402.

[0027] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 5 and Figure 6As shown, the engaging assembly 7 includes a first fixed shell 701, which is fixed to one side of the upper mold 2. A support frame 702 is fixedly connected to the inner wall of the first fixed shell 701. A protrusion 703 is fixedly connected to the bottom of the support frame 702. A latch 704 is engaged with the outer wall of the protrusion 703. A fixing block 705 is fixedly connected to one side of the latch 704. A return spring 706 is provided at the bottom of the fixing block 705. A connecting frame 707 is fixedly connected to the bottom of the return spring 706. A second fixed shell 708 is fixedly connected to the bottom of the connecting frame 707. First, the upper mold 2 and the lower mold 6 are closed. During the closing process, it is possible to... The upper mold 2 moves the sliding rod 5, which slides inside the lower mold 6. The upper mold 2 moves the first fixed shell 701, which in turn moves the support frame 702. The support frame 702 moves the protrusion 703, which presses against the latch 704. The latch 704 moves the fixing block 705, which stretches the return spring 706. The latch 704 engages with the protrusion 703. After engagement, the return spring 706 resets the latch 704.

[0028] Furthermore, such as Figure 6 As shown, the support frame 702 forms a locking structure with the latch 704 through the protrusion 703, and the outer diameter of the protrusion 703 matches the inner diameter of the latch 704. The outer wall of the protrusion 703 is fitted to the inner wall of the latch 704. Through the protrusion 703, the protrusion 703 can lock the latch 704 by being pushed by the support frame 702.

[0029] Furthermore, such as Figure 6 As shown, the fixed block 705 forms an elastic structure with the connecting frame 707 through the return spring 706, and the return spring 706 is disposed between the fixed block 705 and the connecting frame 707. Through the provided return spring 706, the fixed block 705 can drive the return spring 706 to stretch, and the return spring 706 can rebound and reset under the support of the connecting frame 707.

[0030] Furthermore, such as Figure 6 As shown, there are two return springs 706 on one side of the protrusion 703, and the two return springs 706 are symmetrically arranged with the vertical line of the protrusion 703 as the axis of symmetry. The two return springs 706 can both spring back and reset the latch 704.

[0031] Working principle: First, the upper mold 2 and the lower mold 6 are closed. During the closing process, the upper mold 2 moves the sliding rod 5, which slides inside the lower mold 6. This causes the upper mold 2 to move the first fixed shell 701, which in turn moves the support frame 702. The support frame 702 then moves the protrusion 703, which presses against the latch 704. This latch 704 then moves the fixing block 705, allowing the fixing block 705 to move. 05 drives the return spring 706 to stretch, which allows the latch 704 to engage with the protrusion 703. After engagement, the return spring 706 drives the latch 704 to reset. After closing, by injecting molding liquid into the injection port 1, the molding liquid can flow out from the channel port 401 and enter the mold cavity 404 along the flow channel 402, filling the mold cavity 404. This allows the boxed parts mold to be formed inside the upper mold 2 and the lower mold 6, finally obtaining the sprue 403 and the workpiece 405.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
