Description

Technical Field

[0001] This utility model relates to the field of die-casting machine technology, specifically to an aluminum plate die-casting device. Background Technology

[0002] Aluminum alloy die casting technology, as one of the core processes in modern manufacturing, is widely used in the automotive, aerospace, electronics and communications, and construction industries. Its core principle involves injecting molten aluminum alloy at high speed into a steel mold cavity under high pressure, and then rapidly cooling and solidifying it under pressure. This process offers significant advantages such as high production efficiency, high casting precision, and excellent surface quality.

[0003] In the die-casting process of architectural aluminum, the cavity surface needs to be evenly covered with a release coating to prevent castings from sticking together, improve surface quality, and extend mold life. However, traditional processes relying on manual spraying or fixed spraying equipment still have many shortcomings:

[0004] (1) Uneven coverage: Manual spraying is easily affected by the operation method, resulting in local coating accumulation or absence in the cavity, causing surface defects of the casting (such as flow marks and cold shuts);

[0005] (2) Low efficiency: Fixed spraying devices cannot dynamically adjust the spraying position according to the cavity structure, requiring multiple operations to complete the coverage, which increases the production cycle;

[0006] (3) Material waste: Excessive spraying of paint will drip onto the outside of the mold, causing waste of raw materials and environmental pollution. Utility Model Content

[0007] The purpose of this utility model is to provide a technical solution for an aluminum plate die-casting device to address the shortcomings mentioned in the background art.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] An aluminum plate die casting device is provided, including a horizontal die casting machine. A set of cavity coating covering mechanism is provided on both the left and right side walls of the horizontal die casting machine. The horizontal die casting machine includes a base, a mold closing mechanism fixed at the middle position of the top of the base, and a hydraulic mechanism fixed at the front position of the top of the base. An injection mechanism is fixedly connected to the right side of the top surface of the base.

[0010] Each set of cavity coating covering mechanisms includes two support rods and an electric telescopic rod fixed to the outer end of the support rods. A support plate is connected to the telescopic end of the electric telescopic rod. A water pump is fixed to the rear side wall of the electric telescopic rod. A water tank is fixed to the outer side wall of the electric telescopic rod. The pump's suction end is connected to a suction pipe that penetrates into the water tank. The pump's delivery end is connected to a delivery pipe, and several atomizing nozzles are connected to the delivery pipe.

[0011] As a preferred embodiment of the aluminum plate die-casting device, the mold closing mechanism includes a movable half-mold at the front position and a fixed half-mold at the rear position, and the cavity coating covering mechanism is fixed to the left and right side walls of the movable half-mold and the fixed half-mold respectively.

[0012] As a preferred embodiment of the aluminum plate die-casting device, a fixing plate is fixedly connected to the inner end of each support rod, and the fixing plate is fixed to the left and right side walls of the movable half mold and the fixed half mold respectively by bolts.

[0013] As a preferred embodiment of the aluminum plate die-casting device, the extension stroke of the electric telescopic rod is 1 / 2 of the width of the movable half mold and the fixed half mold, and after the electric telescopic rod is fully retracted, the support plate and the atomizing nozzle are located on the left and right sides of the movable half mold and the fixed half mold, and there is no contact with the side walls of the movable half mold and the fixed half mold.

[0014] As a preferred embodiment of the aluminum plate die-casting device, the interior of the water tank is provided with a release coating, and a liquid level sensor is installed in the inner cavity of the water tank, with an inlet nozzle installed on the top surface of the water tank.

[0015] As a preferred embodiment of the aluminum plate die-casting device, the infusion tube is divided into two parts: a flexible tube and a rigid tube. The section of the infusion tube connected to the water pump is a flexible tube, and the section of the infusion tube connected to the atomizing nozzle is a rigid tube.

[0016] As a preferred embodiment of the aluminum plate die-casting device, the spraying end of the atomizing nozzle is inclined toward the cavity end face where the movable half mold and the fixed half mold are close to each other.

[0017] As a preferred embodiment of the aluminum plate die-casting device, a connecting rod is fixed on the section of the infusion pipe away from the water pump, and a plastic liner is connected to the end of the connecting rod. The support plate is fixed to the plastic liner with adhesive, and the telescopic shaft of the electric telescopic rod is fixedly connected to the outer sidewall of the plastic liner.

[0018] As a preferred embodiment of the aluminum plate die-casting device, when the electric telescopic rod extends, the end face of the support plate away from the plastic liner makes slight contact with the cavity end faces of the movable half mold and the fixed half mold, respectively, to scrape off excess paint.

[0019] The beneficial effects of this utility model are:

[0020] In this aluminum plate die-casting device, two sets of cavity coating covering mechanisms are respectively located on the left and right side walls of the movable half-mold and the fixed half-mold, which can comprehensively and evenly cover the cavity end face with release coating, facilitating subsequent demolding. The electric telescopic rod can drive the support plate and atomizing nozzle to move. When extended, it brings the atomizing nozzle closer to the cavity for precise spraying. When retracted, it does not occupy space and avoids interfering with operations such as mold closing. The slight contact between the support plate and the cavity end face can scrape off excess coating, ensuring appropriate coating thickness and improving die-casting quality. The water tank is equipped with a liquid level sensor to know the remaining coating in time, and the liquid inlet nozzle makes it easy to replenish. The atomizing nozzle is set at an angle, making the coating spray direction more reasonable and better covering the cavity, thus improving overall production efficiency and product quality.

[0031] Example 1:

[0032] like Figures 1 to 3As shown, this embodiment provides an aluminum plate die-casting device, including a horizontal die-casting machine 1 and two sets of cavity coating covering mechanisms 2. The base 11 of the horizontal die-casting machine 1 is placed horizontally, with a mold closing mechanism 12 fixed at the top middle section, a hydraulic mechanism 13 fixed at the front section, and an injection mechanism 14 fixed at the right side of the top surface. The mold closing mechanism 12 has a movable half-mold at the front and a fixed half-mold at the rear. The two sets of cavity coating covering mechanisms 2 are respectively fixed to the left and right side walls of the movable half-mold and the fixed half-mold. In each set of cavity coating covering mechanisms 2, the inner ends of two support rods 21 are fixedly connected to a fixing plate 29, and the fixing plate 29 is fixed to the left and right side walls of the movable half-mold or the fixed half-mold by bolts. An electric telescopic rod 210 is fixed to the outer end of the support rod 21. The telescopic end of the electric telescopic rod 210 is connected to the support plate 27. A water pump 24 is fixed to the rear side wall of the electric telescopic rod 210, and a water tank 23 is fixed to the outer side wall. The water tank 23 contains release coating, and a liquid level sensor is installed inside the water tank 23. An inlet nozzle is installed on the top surface. The pump 24's suction end is connected to a suction pipe 22 that penetrates into the water tank 23, and its delivery end is connected to a delivery pipe 25. The delivery pipe 25 is divided into two parts: a flexible section connected to the pump 24 and a rigid section connected to the atomizing nozzle 26. A connecting rod 28 is fixed to the delivery pipe 25, and a plastic liner is connected to the end of the connecting rod 28. The support plate 27 is fixed to the plastic liner with adhesive. The telescopic shaft of the electric telescopic rod 210 is fixedly connected to the outer side wall of the plastic liner.

[0033] The spray tip of the atomizing nozzle 26 is tilted towards the cavity end faces of the movable and fixed half molds that are close to each other. The extension stroke of the electric telescopic rod 210 is 1 / 2 of the width of the movable and fixed half molds. After the electric telescopic rod 210 is fully retracted, the support plate 27 and the atomizing nozzle 26 are located on the left and right sides of the movable and fixed half molds, and there is no contact with the side walls of the movable and fixed half molds. During operation, when release coating needs to be applied, the electric telescopic rod 210 extends, bringing the support plate 27 and the atomizing nozzle 26 closer to the cavity end face. The water pump 24 operates, delivering the release coating in the water tank 23 to the atomizing nozzle 26 through the extraction pipe 22 and the delivery pipe 25. The atomizing nozzle 26 sprays the coating onto the cavity end face. The end face of the support plate 27 away from the plastic liner makes slight contact with the cavity end faces of the movable half mold and the fixed half mold, scraping off excess coating. After application, the electric telescopic rod 210 retracts, returning the support plate 27 and the atomizing nozzle 26 to their original positions.

[0034] Example 2:

[0035] The aluminum plate die-casting device in this embodiment is basically the same as that in Embodiment 1. The main difference is that the initial position of the electric telescopic rod 210 is slightly adjusted during installation in this embodiment. In its fully retracted state, the distance between the support plate 27 and the atomizing nozzle 26 and the side walls of the movable and fixed half-molds is slightly greater than in Embodiment 1, but still ensures no contact. The initial liquid level of the release coating in the water tank 23 is adjusted according to actual production needs. In actual use, when applying the release coating, the electric telescopic rod 210 extends, bringing related components closer to the cavity end face. The water pump 24 starts to extract the coating and deliver it to the atomizing nozzle 26 for spraying. When the support plate 27 contacts the cavity end face, due to the different initial position, the pressure distribution on the cavity end face is slightly different from that in Embodiment 1 when scraping off excess coating, but it still achieves the purpose of scraping off excess coating. After application, the electric telescopic rod 210 retracts and resets.

[0036] Example 3:

[0037] The aluminum plate die-casting device in this embodiment is basically the same as that in Embodiment 1. The main difference is that the length ratio of the flexible tube and the rigid tube of the infusion tube 25 has been adjusted in this embodiment, with the flexible tube being relatively longer. During the application of the release coating, when the electric telescopic rod 210 extends and moves the atomizing nozzle 26 closer to the cavity end face, the longer flexible tube allows the atomizing nozzle 26 to move more flexibly and adapt to minor positional deviations.

[0038] A filter device is installed at the inlet nozzle on the top of the water tank 23 to prevent impurities from entering the water tank 23 and affecting the quality of the release coating. During operation, the electric telescopic rod 210 extends, the water pump 24 operates, and the release coating enters the water tank 23 through the inlet nozzle with the filter device. It then reaches the atomizing nozzle 26 for spraying through the suction pipe 22 and the delivery pipe 25. The support plate 27 scrapes off excess coating from the cavity end face. After the coating is completed, the electric telescopic rod 210 retracts, and all components return to their initial positions.

[0039] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0040] When it is necessary to apply release coating to the cavity of the die-cast aluminum plate, first activate the electric telescopic rod 210. The telescopic shaft of the electric telescopic rod 210 extends, driving the plastic liner to move. This, in turn, moves the support plate 27, the infusion pipe 25 fixed on the plastic liner, and the atomizing nozzle 26 closer to the cavity end faces of the movable and fixed half molds. When the electric telescopic rod 210 extends to the appropriate position, positioning the atomizing nozzle 26 to effectively spray the release coating onto the cavity end face, activate the water pump 24. The water pump 24 draws release coating from the water tank 23 through the extraction pipe 22. The release coating passes through the flexible and rigid parts of the delivery pipe 25 and reaches the atomizing nozzle 26. The atomizing nozzle 26 sprays the release coating in a mist form onto the cavity end faces of the movable half mold and the fixed half mold that are close to each other. During the spraying process, as the electric telescopic rod 210 continues to extend or remains in place for a certain period of time, the cavity end faces can be evenly covered with the release coating. At the same time, the end face of the support plate 27 away from the plastic liner will interact with the movable half mold. The cavity end faces of the half mold and the fixed half mold are in slight contact. During the movement or holding of the electric telescopic rod 210, the support plate 27 will scrape off the excess paint on the cavity end face. After the release paint is applied to the cavity end face, the water pump 24 is turned off to stop the extraction and spraying of the release paint. Then, the electric telescopic rod 210 is controlled to retract. The telescopic shaft of the electric telescopic rod 210 drives the plastic liner, support plate 27, infusion pipe 25 and atomizing nozzle 26 to move away from the cavity end face. When the electric telescopic rod 210 is fully retracted, the support plate 27 and atomizing nozzle 26 are located on the left and right sides of the movable half mold and the fixed half mold and are not in contact with the side walls of the movable half mold and the fixed half mold. At this time, the application of the release paint to the cavity is completed, and the subsequent aluminum plate die casting operation can be carried out. During the operation of the device, the liquid level sensor in the water tank 23 will monitor the liquid level of the release paint in real time. When the liquid level is lower than a certain level, the release paint can be added to the water tank 23 through the liquid inlet at the top of the water tank 23.

[0041] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
