[0002] Mold technology is one of the core processes in modern industrial manufacturing. It enables the efficient forming of materials through precisely designed molds and is widely used in the automotive, electronics, home appliance, and aerospace industries. Its core lies in utilizing the cavity structure of the mold to cause metal or non-metal materials to undergo plastic deformation under pressure, temperature, or injection molding, forming parts that meet design requirements. Mold technology covers the entire process of design, manufacturing, debugging, and maintenance. In the design stage, 3D modeling and simulation analysis are carried out using CAD / CAE software to optimize the structure and reduce defects. The manufacturing process relies on high-precision machining equipment such as CNC and EDM machines to ensure that the mold dimensional accuracy reaches the micron level. In the debugging stage, parameters are adjusted through trial molding to ensure product qualification rate. Later maintenance involves surface treatment to extend the mold life. Mold technology is evolving towards intelligence and high speed.

[0003] However, in existing technologies, molds with concave structures are inconvenient for demolding, which can lead to a complicated and time-consuming demolding process, and may also cause damage to the workpiece, affect the appearance quality of the product and production efficiency. Therefore, we need a mold for multi-hollow products. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for multi-hollow products, so as to solve the existing problems mentioned in the background art, which are that molds with concave structures are inconvenient to demold, which easily lead to a complicated and time-consuming demolding process, and may cause damage to the workpiece, affect the appearance quality of the product and production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for multi-hollow products, including a lower sealing plate, a rear template on the top of the lower sealing plate, a front template on the top of the rear template, an upper sealing plate on the top of the front template, an inwardly recessed component inside the front template, a fixing component inside the rear template, the inwardly recessed component including a positioning groove located on the top of the rear template, a slider at the bottom of the upper sealing plate, a first bolt inside the upper sealing plate, a fixing block at the bottom of the front template, a sliding groove on the top of the fixing block, a positioning block at the bottom of the front template, a second bolt inside the positioning block, a workpiece inside the front template, a groove on the outer wall of the workpiece, and a protrusion fixedly connected to one side of the fixing block.

[0006] Preferably, the fixing block forms a sliding structure with the upper sealing plate through a sliding groove, and the inner diameter of the sliding groove matches the outer diameter of the slider, and the inner wall of the sliding groove is fitted to the outer wall of the slider.

[0007] Preferably, the slider is detachable from the upper sealing plate by a first bolt, and the first bolt passes through the interior of the upper sealing plate and the slider for fixation.

[0008] Preferably, the fixing block forms a locking structure with the workpiece through the protrusion, and the inner diameter of the groove matches the outer diameter of the protrusion, and the inner wall of the groove fits against the outer wall of the protrusion.

[0009] Preferably, the fixing component includes a positioning cylinder, which is disposed inside the rear template, a positioning rod is fixedly connected inside the upper sealing plate, and a fixing cylinder is installed inside the front template.

[0010] Preferably, the rear template forms a locking structure with the upper sealing plate through the positioning cylinder, and the inner diameter of the positioning cylinder matches the outer diameter of the positioning rod, and the inner wall of the positioning cylinder is fitted to the outer wall of the protrusion.

[0011] Preferably, there are multiple positioning rods on the upper sealing plate, and the multiple positioning rods are evenly spaced inside the upper sealing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. To address the problem that existing molds with concave structures are inconvenient to demold, leading to complex and time-consuming demolding processes, and potentially causing workpiece damage, affecting product appearance quality and production efficiency, this application proposes a design where an upper sealing plate drives a slider to move. The slider slides down within a groove and abuts against a positioning groove, pushing a fixed block forward between two positioning blocks. This causes a protrusion to move forward, allowing the mold cavity to be recessed for injection molding. After injection molding, cooling, and mold opening, the upper sealing plate is moved again to drive the slider upward, causing the fixed block and protrusion to move backward. Finally, the workpiece is ejected by an ejector pin. This design achieves efficient and safe demolding of concave structure molds, improving product output quality and production efficiency. 2. To address the problems of poor mold closing accuracy, misalignment, mold damage, and poor workpiece quality caused by existing molds, which increase production failure rate and costs, this application proposes a positioning rod and a positioning cylinder. When the upper sealing plate moves, it drives the positioning rod to move, and the positioning rod accurately passes through the fixed cylinder. This process acts as a precise path for mold closing. Subsequently, the upper sealing plate drives the front template to move, and the positioning rod and positioning cylinder smoothly engage, providing double insurance for the merging of the front and rear templates. Ultimately, this achieves precise and stable merging of the front and rear templates, effectively improving the mold closing accuracy and ensuring the workpiece forming quality.

[0015] 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.

[0016] This utility model embodiment provides a mold for multi-hollow products, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the assembly includes a lower sealing plate 1, a rear template 2 on top of the lower sealing plate 1, a front template 3 on top of the rear template 2, an upper sealing plate 4 on top of the front template 3, a recessed component 5 inside the front template 3, a fixing component 6 inside the rear template 2, the recessed component 5 including a positioning groove 501 located on top of the rear template 2, a slider 502 at the bottom of the upper sealing plate 4, a first bolt 503 inside the upper sealing plate 4, a fixing block 504 at the bottom of the front template 3 with a sliding groove 505 on top, a positioning block 506 at the bottom of the front template 3 with a second bolt 507 inside the positioning block 506, and a workpiece 508 inside the front template 3 with a groove 5 on its outer wall. 09. A protrusion 510 is fixedly connected to one side of the fixed block 504. The upper sealing plate 4 drives the slider 502 to move, so that the slider 502 slides down inside the slide groove 505, so that the slider 502 abuts against the positioning groove 501, so that the fixed block 504 moves forward between the two positioning blocks 506, so that the fixed block 504 drives the protrusion 510 to move forward, so that the mold cavity is concave, thereby completing the concavity of the workpiece 508. Then injection molding is performed. After injection molding is completed and cooling is performed, the mold is opened after cooling. The upper sealing plate 4 is moved, so that the upper sealing plate 4 drives the slider 502 to move upward, so that the slider 502 slides upward in the slide groove 505, so that the fixed block 504 moves backward, so that the fixed block 504 drives the protrusion 510 to move backward, and then the ejector pin pushes out the workpiece 508, thereby completing the production of the workpiece 508.

[0017] Further such as Figure 3 , Figure 5 and Figure 6 As shown, the fixed block 504 forms a sliding structure with the upper sealing plate 4 through the slide groove 505, and the inner diameter of the slide groove 505 matches the outer diameter of the slider 502. The inner wall of the slide groove 505 is fitted to the outer wall of the slider 502. Through the slide groove 505, the slider 502 can slide inside the slide groove 505, which causes the upper sealing plate 4 to move the slider 502. The slider 502 slides inside the slide groove 505, which causes the fixed block 504 to move, realizing the linkage between the components. This provides basic support for the flexible operation and functional realization of the overall structure and is conducive to demolding.

[0018] Further such as Figure 4 As shown, the slider 502 is detachable from the upper sealing plate 4 by means of the first bolt 503. The first bolt 503 passes through the upper sealing plate 4 and the interior of the slider 502 for fixation. The first bolt 503 can fix the slider 502 to the bottom of the upper sealing plate 4, ensuring the stability of the connection between the slider 502 and the upper sealing plate 4, avoiding loosening or displacement during use, ensuring the reliability and accuracy of the overall structure during operation, and facilitating stable operation of the equipment.

[0019] Further, such as Figure 6 , Figure 7 and Figure 8 As shown, the fixing block 504 forms a locking structure with the workpiece 508 through the protrusion 510, and the inner diameter of the groove 509 matches the outer diameter of the protrusion 510. The inner wall of the groove 509 is fitted to the outer wall of the protrusion 510. Through the protrusion 510, the protrusion 510 can be locked with the groove 509 by the action of the fixing block 504, so that the manufacturing mold is concave and the outer wall of the workpiece 508 is concave.

[0020] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the fixing component 6 includes a positioning cylinder 601, which is located inside the rear template 2. A positioning rod 602 is fixedly connected inside the upper sealing plate 4, and a fixing cylinder 603 is installed inside the front template 3. By moving the upper sealing plate 4, the upper sealing plate 4 drives the positioning rod 602 to move, so that the positioning rod 602 passes through the fixing cylinder 603, and the upper sealing plate 4 drives the front template 3 to move, so that the positioning rod 602 engages with the positioning cylinder 601, and the front template 3 merges with the rear template 2, thereby completing precise mold closing.

[0021] Further, such as Figure 2 and Figure 3 As shown, the rear template 2 forms a locking structure with the upper sealing plate 4 through the positioning cylinder 601, and the inner diameter of the positioning cylinder 601 matches the outer diameter of the positioning rod 602. The inner wall of the positioning cylinder 601 is fitted to the outer wall of the protrusion 510. Through the positioning cylinder 601, the positioning cylinder 601 can lock with the positioning rod 602 under the support of the rear template 2, effectively ensuring the positioning accuracy of the rear template 2 and the front template 3, preventing offset or misalignment during operation, improving the mold demolding accuracy, and providing a reliable guarantee for high-quality product production.

[0022] Further, such as Figure 3 As shown, there are multiple positioning rods 602 on the upper sealing plate 4, and the multiple positioning rods 602 are evenly spaced inside the upper sealing plate 4. Through the positioning rods 602, the positioning cylinder 601 can be locked by the upper sealing plate 4, making the opening and closing of the mold more precise and facilitating the demolding of the workpiece 508.

[0023] Working principle: During use, when mold closing is required, the upper sealing plate 4 can be moved, causing the positioning rod 602 to move and pass through the fixed cylinder 603. This causes the upper sealing plate 4 to move the front mold plate 3, making the positioning rod 602 engage with the positioning cylinder 601, thus merging the front mold plate 3 with the rear mold plate 2, thereby completing precise mold closing. The upper sealing plate 4 also causes the slider 502 to move, sliding down inside the slide groove 505. This causes the slider 502 to abut against the positioning groove 501, thus merging the fixed block 50. 4. Move forward between the two positioning blocks 506, so that the fixing block 504 drives the protrusion 510 to move forward, so that the mold cavity is recessed, thereby completing the recess of the workpiece 508. Then, injection molding is performed. After injection molding is completed and cooling is performed, the mold is opened and the upper sealing plate 4 is moved, so that the upper sealing plate 4 drives the slider 502 to move upward, so that the slider 502 slides upward in the slide groove 505, so that the fixing block 504 moves backward, so that the fixing block 504 drives the protrusion 510 to move backward, and then the workpiece 508 is ejected by the ejector pin, thereby completing the production of the workpiece 508.
