Description

Technical Field

[0001] This utility model belongs to the technical field of demolding devices, specifically an automatic demolding device. Background Technology

[0002] In modern manufacturing, particularly in industries such as plastic molding, metal die casting, and rubber product manufacturing, demolding is a crucial step in the product production process. With the increasing variety of products, the continuous expansion of production scale, and the ever-increasing demands for production efficiency and product quality, traditional demolding methods face numerous challenges.

[0003] Meanwhile, the patent specification with application number CN218892222U discloses an automatic demolding and unloading device, which "includes a base plate, a placement plate on the upper surface of the base plate, and vertical columns at the corners. A first limiting plate passes through the columns and is fixedly connected to the middle part of the base plate. A second limiting plate passes through the columns and is fixedly connected to the first limiting plate. A cylinder is provided on the upper surface of the second limiting plate. A pressure plate is provided between the base plate and the first limiting plate and is fixedly connected to the cylinder."

[0004] In the current demolding process, most products are demolded manually. This not only consumes a lot of manpower and time, but also makes it difficult to ensure that the force and angle of demolding are consistent each time, which can easily lead to product damage during demolding and a high defect rate. Secondly, most existing equipment does not have a cooling device, and it is often necessary to wait for the molded product to cool to a suitable temperature before demolding, which greatly reduces production efficiency.

[0005] Therefore, an automatic demolding device is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an automatic demolding device, which effectively avoids product demolding damage caused by inconsistent demolding force and angle due to manual demolding, significantly reduces the defect rate, greatly improves production efficiency, and makes the entire production process more efficient and smooth.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic demolding device, comprising an operating table, four electric telescopic rods fixedly connected to the top of the operating table, a cover plate fixedly connected to the top of the four electric telescopic rods, a mold fixedly connected to the bottom of the cover plate, a demolding mechanism provided at the top of the operating table, the demolding mechanism comprising a cylinder fixedly connected to the operating table, a slider fixedly connected to the output end of the cylinder, four support blocks fixedly connected to the top of the operating table, a demolding frame fixedly connected to the top of the four support blocks, a rectangular groove opened at the top of the demolding frame, a shaping frame installed inside the rectangular groove, a through groove opened on the lower inner wall of the rectangular groove, a sliding rod slidably connected to the top of the slider, the top of the sliding rod penetrating the through groove and fixedly connected to a top plate, the outer surface of the top plate fitting against the inner surface of the shaping frame, and a cooling mechanism provided between the shaping frame and the rectangular groove.

[0010] Preferably, a slide rail is fixedly connected to the top of the operating table, and the slider is slidably connected to the operating table through the slide rail.

[0011] Preferably, the cooling mechanism includes two cooling pipes, which are wound around the outer surface of the shaping frame and the inner surface of the rectangular groove, and are connected by a pipe. A heat insulation frame is fixedly connected to the upper part between the inner surface of the rectangular groove and the outer surface of the shaping frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a demolding mechanism that, under the action of a cylinder, uses the interaction of inclined surfaces to make the slide bar rise smoothly, causing the top plate to separate from the molding frame. This ensures the accuracy and stability of the separation action between the mold and the product during the demolding process, effectively avoids product demolding damage caused by inconsistent demolding force and angle, and significantly reduces the defect rate.

[0016] 2. This utility model uses a cooling mechanism, under the action of a transfer pump, to rapidly circulate coolant in the cooling pipes, enabling the molding frame to cool down quickly and greatly shortening the cooling time of the molded products. Compared with the traditional situation where there is no cooling device and a long time is required to wait for the product to cool down before demolding, this greatly improves production efficiency and makes the entire production process more efficient and smooth.

[0027] 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.

[0028] like Figures 1 to 5 As shown, this utility model provides an automatic demolding device, including an operating table 1. Four electric telescopic rods 4 are fixedly connected to the top of the operating table 1. A cover plate 3 is fixedly connected to the top of the four electric telescopic rods 4. A mold 31 is fixedly connected to the bottom of the cover plate 3. A demolding mechanism 6 is provided at the top of the operating table 1.

[0029] The demolding mechanism 6 includes a cylinder 67, which is fixedly connected to the operating table 1. A slider 66 is fixedly connected to the output end of the cylinder 67. Four support blocks 2 are fixedly connected to the top of the operating table 1. A demolding frame 62 is fixedly connected to the top of the four support blocks 2. A rectangular groove 68 is opened at the top of the demolding frame 62. A molding frame 64 is installed inside the rectangular groove 68. A through groove is opened on the lower inner wall of the rectangular groove 68. A sliding rod 663 is slidably connected to the top of the slider 66. The bottom end of the sliding rod 663 and the top end of the slider 66 are both inclined at the same angle. The top end of the sliding rod 663 passes through the through groove and is fixedly connected to a top plate 65. The outer surface of the top plate 65 is flush with the molding frame 64. The inner surfaces are in contact with each other. Under the action of cylinder 67, the sliding rod 663 rises smoothly with the help of the interaction of the inclined surfaces, which drives the top plate 65 to separate from the molding frame 64. This ensures the accuracy and stability of the separation action between the mold 31 and the product during the demolding process, effectively avoiding product demolding damage caused by inconsistent demolding force and angle during manual demolding. This makes the demolding action highly accurate and stable, and can strictly follow the preset motion trajectory. It effectively avoids product demolding damage caused by the difficulty in accurately controlling the force and angle during manual demolding, and greatly improves the quality and yield of the product after demolding. A cooling mechanism 5 is provided between the molding frame 64 and the rectangular groove 68.

[0030] Specifically, a limiting groove 661 is provided at the top of the slide bar 663, and a limiting block 662 that works with the limiting groove 661 is fixedly connected to the bottom of the slider 66. The limiting groove 661 at the top of the slide bar 663 and the limiting block 662 at the bottom of the slider 66 cooperate to precisely limit the position of the slide bar 663, prevent it from shifting or shaking during movement, ensure accurate demolding action, ensure stable and reliable demolding process, and maintain the normal operation of the entire demolding mechanism 6.

[0031] like Figures 1 to 5As shown, a slide rail 61 is fixedly connected to the top of the operating table 1. The slider 66 is slidably connected to the operating table 1 through the slide rail 61 to avoid deviating from the predetermined trajectory, ensure that the slide rod 663 drives the top plate 65 to accurately perform the demolding operation, improve the accuracy and stability of the demolding mechanism 6, and ensure the smooth demolding process.

[0032] Furthermore, the cooling mechanism 5 includes two cooling pipes 54, which are wound around the outer surface of the molding frame 64 and the inner surface of the rectangular groove 68, and are connected to each other. A heat insulation frame 63 is fixedly connected to the upper part between the inner surface of the rectangular groove 68 and the outer surface of the molding frame 64. Thermally conductive silicone grease is applied to the contact areas between the cooling pipes 54 and the inner surfaces of the molding frame 64 and the rectangular groove 68. A transfer pump 53 is fixedly connected to the inlet of the cooling pipes 54. The other end of the pump 53 is fixedly connected to a cooling water tank 55 via a pipe. The bottom end of the cooling water tank 55 is fixedly connected to the top end of the operating table 1. The outlet of the cooling pipe 54 is fixedly connected to the cooling water tank 55. A heat dissipation mechanism 7 is installed on the outer surface of the cooling water tank 55. The cooling pipe 54 is wound between the inner surface of the molding frame 64 and the rectangular groove 68. With the help of thermal grease, it can efficiently remove the heat from the molding frame 64, quickly cool and solidify the demolded product, facilitate the product to be removed from the mold 31 and ensure the shape accuracy and quality stability.

[0033] like Figures 1 to 5 As shown, the heat dissipation mechanism 7 includes a cooling fan 51 and a cooling fin assembly 52. ​​One end of the cooling fin assembly 52 is fixedly connected to one end of the cooling water tank 55, and the other end of the cooling fin assembly 52 is fixedly connected to the cooling fan 51. The cooling fan 51 and the cooling fin assembly 52 work together to accelerate the airflow on the surface of the cooling water tank 55, enhance the heat dissipation efficiency, ensure that the coolant temperature in the cooling water tank 55 is suitable, continuously provide low-temperature coolant to the cooling pipe 54, and ensure the normal and stable operation of the cooling mechanism 5.

[0034] It is worth noting that both the molding frame 64 and the cooling water tank 55 are made of aluminum alloy. The good thermal conductivity of aluminum alloy facilitates heat transfer from the molding frame 64 and heat dissipation from the cooling water tank 55, which helps with demolding and product cooling and shaping.

[0035] The transfer pump 53 and cylinder 67 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0036] Working principle and process: The raw material is placed in the molding frame 64, at which time the electric telescopic rod 4 is in the retracted state. Then, the raw material is injected into the molding frame 64. After that, the electric telescopic rod 4 is activated to drive the cover plate 3 to descend, so that the raw material is formed into the desired shape in the molding frame 64. Then, the transfer pump 53 is started to draw out the coolant from the cooling water tank 55 and deliver it to the cooling pipe 54. The coolant circulates in the cooling pipe 54, which is spirally connected between the outer surface of the molding frame 64 and the inner surface of the rectangular groove 68, thereby accelerating the cooling of the product. At the same time, the heat dissipation mechanism 7 installed on the outer surface of the cooling water tank 55 is also operating, and the cooling fan 51 cools the heat dissipation fin assembly 52. A blower is used to dissipate the heat absorbed by the coolant in the cooling water tank 55 into the surrounding environment to maintain the coolant's low temperature. Once the product has cooled to a suitable temperature, the electric telescopic rod 4 is restarted to raise the cover plate 3. Then, the cylinder 67 is activated to push the slider 66 to slide on the slide rail 61. Since the bottom end of the slider 663 and the top end of the slider 66 are both inclined and cooperate with the limiting groove 661 and the limiting block 662, the movement of the slider 66 will cause the slider 663 to slide upward. The slider 663 will drive the top plate 65 to rise, and the top plate 65 will gradually separate from the molding frame 64, thereby separating the mold 31 from the cooled and formed product inside the molding frame 64, completing the demolding operation.
