Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy processing technology, and in particular to a mold for manufacturing aluminum alloy blocks. Background Technology

[0002] In the research and development of aluminum alloy materials, it is necessary to explore the material properties through performance tests such as tensile strength and hardness to develop new products suitable for aerospace, automotive manufacturing and other fields. In the quality inspection stage, the performance indicators of the samples are important standards for determining whether the products are qualified. However, the existing mold technology for manufacturing aluminum alloy block samples is limited, making it difficult to accurately control the forming process. This leads to problems such as dimensional deviations, internal porosity and surface roughness in the samples, which greatly affects the accuracy of test data and hinders the research and development progress and quality control. Optimizing the mold design is necessary to ensure the quality of aluminum alloy block samples.

[0003] In traditional mold design, after the aluminum alloy block is formed, the aluminum alloy material cools and shrinks, closely adhering to the mold wall. In addition, due to the unreasonable demolding structure design, the demolding resistance is relatively large. Manual demolding has become a common method. Operators need to use tools such as pry bars and ejector pins to find leverage points in the gaps of the mold cavity and repeatedly pry the aluminum alloy block. This process is not only time-consuming and labor-intensive, increasing labor intensity, but also causes damage to the product appearance and reduces product quality. Utility Model Content

[0004] This invention solves the problems mentioned in the background art by automating precise demolding, using a knife-shaped front end that automatically embeds into the bottom of the aluminum alloy block, completely replacing traditional pry bars, ejector pins, and manual demolding tools. This reduces the manual dependence in the demolding process to zero, significantly improving operational safety and product appearance qualification rate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mold for manufacturing aluminum alloy blocks, comprising a lower mold mechanism, wherein the top of the lower mold mechanism contacts an upper mold mechanism, and the bottom of the upper mold mechanism is fixedly connected to a punch mechanism; The punch mechanism includes a punch body. The punch body has two sets of embedded grooves inside. The inner surface of the two sets of embedded grooves is slidably embedded with embedded plates. An adjustment plate is fixedly connected to one side of the outer wall of each of the two embedded plates. A set of toothed grooves is opened inside the two adjustment plates. A linkage rod is fixedly connected to one side of the inner wall of each of the two adjustment plates. An L-shaped spade plate is fixedly connected to the bottom of each of the two linkage rods. A motor is fixedly connected inside the punch body, and a gear is fixedly connected to the rotating end of the motor. The gear is meshed inside two sets of tooth grooves.

[0006] Preferably, the punch body has two sets of L-shaped moving grooves pre-set inside, and two L-shaped shovels are respectively movably embedded inside the L-shaped moving grooves.

[0007] Preferably, the upper mold mechanism includes an upper mold body, and two telescopic coil springs are fixedly connected inside the upper mold body. The retracted ends of the two telescopic coil springs are respectively wound with a set of cables, and the outer walls of the two sets of cables are movably embedded inside the upper mold body.

[0008] Preferably, a lower molded boss is fixedly connected to the bottom of the upper mold body, and side blocks are fixedly connected to the bottom of the two sets of cables respectively. One side of the outer wall of the two side blocks is movably connected to the interior of the mold body. An electric telescopic rod is fixedly connected to the center of the bottom of the lower molded boss, and the telescopic end of the electric telescopic rod is fixedly connected to the top of the mold body.

[0009] Preferably, the lower mold mechanism includes a lower mold body, and the lower mold body has an injection groove inside.

[0010] Preferably, the inner surface wall of the lower mold body has two side grooves, and the side blocks are respectively placed inside the side grooves. A set of limiting rods is fixedly connected to the top of the lower mold body, and the set of limiting rods is movably embedded inside the upper mold body.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the product can automatically and accurately demold, eliminating the problems of human damage and safety hazards. Through the meshing transmission of the motor-driven gear and tooth groove in the punch mechanism, the L-shaped spatula is driven to automatically embed into the bottom of the aluminum alloy block with the blade-shaped front end, completely replacing the traditional manual demolding tools such as pry bars and ejector pins. This design eliminates quality defects such as scratches and deformation on the product surface caused by manual operation, while avoiding the safety risk of tools slipping and injuring people. It reduces the manual dependence of the demolding process to zero, significantly improving operational safety and product appearance qualification rate.

[0012] 2. In this utility model, the product adhesion is reduced by the shaking action of the punch mechanism during the demolding stage. This mechanism not only solves the problem of high demolding resistance caused by cooling and shrinkage of traditional molds, but also greatly shortens the demolding time of a single demolding through the automation process, while ensuring the dimensional accuracy (error ≤ 0.1mm) and internal density of the aluminum alloy block, effectively avoiding defects caused by internal porosity and surface roughness.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: Refer to Figure 1 - Figure 7 As shown: A mold for manufacturing aluminum alloy blocks includes a lower mold mechanism 1, an upper mold mechanism 2 in contact with the top of the lower mold mechanism 1, and a punch mechanism 3 fixedly connected to the bottom of the upper mold mechanism 2. The punch mechanism 3 includes a punch body 31. The punch body 31 has two sets of embedded grooves 311 inside. The inner surface of the two sets of embedded grooves 311 is slidably embedded with embedded plates 32. An adjusting plate 33 is fixedly connected to one side of the outer wall of the two embedded plates 32. A set of toothed grooves 331 is opened inside the two adjusting plates 33. A linkage rod 34 is fixedly connected to one side of the inner wall of the two adjusting plates 33. An L-shaped spade plate 341 is fixedly connected to the bottom of the two linkage rods 34. A motor 35 is fixedly connected inside the punch body 31. A gear 351 is fixedly connected to the rotating end of the motor 35. The gear 351 is meshed inside two sets of tooth grooves 331. Two sets of L-shaped moving grooves 312 are pre-set inside the punch body 31, and two L-shaped shovels 341 are respectively movably embedded inside the L-shaped moving grooves 312.

[0018] In this embodiment, when the lower mold mechanism 1 and the upper mold mechanism 2 are in a closed state, the punch mechanism 3 can be effectively placed inside the injection molding tank 111 and form a cavity between them. Then, the molten raw material is injected into the cavity position by an external injection molding device. After the device is cooled, the injection-molded aluminum alloy block needs to be demolded. At this time, the motor 35 is started to drive the gear 351 to rotate with the generated power. It then meshes with the two sets of tooth grooves 331. With the cooperation of the two sets of insert plates 32 moving inside the inner insert groove 311, the two adjusting plates 33 are kept moving towards both ends. This movement is mediated by the linkage rod 34 to keep the L-shaped spade plate 341 embedded and moving inside the L-moving groove 312. The L-shaped spade plate 341 moves towards both ends. Because its front end is set in a knife-edge shape, it can easily embed itself into the bottom of the molded aluminum alloy block.

[0019] Example 2: According to Figure 1 - Figure 5 As shown: The upper mold mechanism 2 includes an upper mold body 21. Two telescopic coil springs 22 are fixedly connected inside the upper mold body 21. A set of cables 221 are wound around the retracted ends of the two telescopic coil springs 22 respectively. The outer walls of the two sets of cables 221 are movably embedded inside the upper mold body 21. A lower molded boss 23 is fixedly connected to the bottom of the upper mold body 21. Side blocks 231 are fixedly connected to the bottom of the two sets of cables 221 respectively. One side of the outer wall of the two side blocks 231 is movably connected to the inside of the punch body 31 respectively. An electric telescopic rod 24 is fixedly connected to the bottom center of the lower molded boss 23, and the telescopic end of the electric telescopic rod 24 is fixedly connected to the top of the punch body 31. The lower mold mechanism 1 includes a lower mold body 11, an injection groove 111 is provided inside the lower mold body 11, and two side grooves 113 are provided on the inner surface wall of the lower mold body 11. Side blocks 231 are respectively placed inside the side grooves 113. A set of limiting rods 12 are fixedly connected to the top of the lower mold body 11, and the set of limiting rods 12 are movably embedded inside the upper mold body 21.

[0020] In this embodiment, with the cooperation of external equipment, the lower mold mechanism 1 and the upper mold mechanism 2 can be effectively kept in a separated state. During this process, the two L-shaped shovels 341 placed at the bottom of the aluminum alloy block can effectively carry out the cooled and formed product. After maintaining the moving height, the motor 35 rotates in the opposite direction, and then the two adjusting plates 33 are retracted, which drives the L-shaped shovels 341 to retract into the interior of the punch body 31. During this process, the electric telescopic rod 24 is energized and expands, which can push the punch mechanism 3 to move downward. During this process, the two side blocks 231 are in a movable connection with the punch body 31 and remain in a swaying state, which can improve the cooling product from falling off the outer wall of the punch mechanism 3. During this movement, the two sets of cables 221 can effectively keep the side blocks 231 and the bottom connected punch mechanism 3 moving up and down. When the electric telescopic rod 24 is retracted, the two telescopic spring coils 22 can effectively retract the two sets of cables 221.

[0021] Working principle: This mold mainly consists of a lower mold mechanism 1, an upper mold mechanism 2, and a punch mechanism 3. Through the coordinated operation of these mechanisms, the aluminum alloy block is formed and demolded. The top of the lower mold mechanism 1 contacts and closes with the upper mold mechanism 2. The punch mechanism 3 rests inside the injection groove 111 of the lower mold mechanism 1. At this time, a cavity for injection molding is formed between the upper mold mechanism 2, the punch mechanism 3, and the lower mold mechanism 1. The limiting rod 12 at the top of the lower mold mechanism 1 is movably embedded inside the upper mold mechanism 2 to ensure precise alignment when the upper and lower molds are closed. Molten aluminum alloy material is injected into the cavity formed above through external injection molding equipment. After the material cools, a solid aluminum alloy block is formed. When it is necessary to demold the cooled and formed aluminum alloy block, the motor 35 inside the punch mechanism 3 is activated. The rotating end of the motor 35 drives the gear 351 to rotate. The gear 351 meshes with the tooth groove 331 inside the adjusting plate 33, causing the two adjusting plates 33 to move in opposite directions to both ends within the embedded groove 311 of the punch body 31. The adjusting plates 33 drive the L-shaped spade 341 at the bottom to move synchronously to both ends within the L-shaped moving groove 312 of the punch body 31 via the linkage rod 34. Since the front end of the L-shaped spade 341 is knife-shaped, it can be easily embedded into the bottom of the formed aluminum alloy block, providing a support point for subsequent demolding. With the cooperation of external equipment The upper mold mechanism 2 and the lower mold mechanism 1 begin to separate. After the electric telescopic rod 24 in the upper mold mechanism 2 is energized, its telescopic end pushes the punch mechanism 3 to move downward. There may be some optimization in the description logic here. In combination with the context, it should actually be that the upper mold mechanism 2 drives the punch mechanism 3 to move upward to achieve separation from the lower mold. During the movement, the side block 231 of the upper mold mechanism 2 falls into the side groove 113 of the lower mold mechanism 1. As the upper and lower molds separate, the L-shaped spade 341 embedded in the bottom of the aluminum alloy block brings the cooled and formed product out of the injection groove 111 of the lower mold. When the upper and lower molds separate to a certain height, the motor 35 rotates in the reverse direction, causing the adjusting plate 33 to retract, driving the L-shaped spade 341 to move downward. The shovel plate 341 retracts into the punch body 31, disengaging from the bottom of the aluminum alloy block. Simultaneously, the electric telescopic rod 24 continues to operate or retracts, pushing the punch mechanism 3 to move up and down. Since the side block 231 is movably connected to the punch body 31, the punch mechanism 3 is in a wobbling state during movement, causing the aluminum alloy block attached to its outer wall to fall off smoothly. During this process, the telescopic wire spring coil 22 in the upper mold mechanism 2 effectively maintains the stability of the side block 231 and the punch mechanism 3 moving up and down through the wound cable 221. When the electric telescopic rod 24 retracts, the telescopic wire spring coil 22 retracts the cable 221, preparing for the next mold closing. By following the steps described above, you can complete the use of a mold for manufacturing aluminum alloy blocks.

[0022] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
