Description

Technical Field

[0001] This utility model belongs to the field of differential pressure casting technology, specifically relating to a siphon-blowing type receiving tray. Background Technology

[0002] Differential pressure casting is an advanced anti-gravity forming technology that produces high-quality, high-performance, and high-strength aluminum alloy castings. The forming temperature of the workpieces is typically above 500℃ or even higher. Currently, when materials are received on pallets and cooled in a water bath before being re-entered into the differential pressure casting machine, residual water droplets can fall into the mold cavity or onto the equipment and surrounding area, significantly impacting product quality, production stability, equipment performance, and costs.

[0003] Impact on product quality: When water droplets fall from the tray into the mold cavity, it causes localized low temperatures and uneven temperature distribution in the mold. This leads to incomplete solidification in some areas during molding, resulting in shrinkage defects within the workpiece or surface defects such as incomplete filling and cold shuts. Simultaneously, water vapor evaporation can be drawn into the workpiece during the next mold cavity molding process, forming circular, smooth-walled pores inside or on the surface of the casting. These defects are explicitly unacceptable according to product standards, fail X-ray and fluorescent flaw detection, and must be scrapped. Such defects severely affect the mechanical properties of the workpiece (especially fatigue strength and elongation), making it unable to withstand the design load. If they leak out, they can compromise the safety of the entire vehicle.

[0004] Impact on Production Stability: Casting mold production maintains a precise and stable temperature field (mold temperature typically between 200-400℃) to ensure that molten metal fills and solidifies according to a preset sequence and speed. Water dripping onto the mold surface creates localized "cold spots." Defects caused by water are random and localized, making it difficult for process engineers to accurately analyze and resolve the problems. They might adjust the injection speed, mold temperature, or cooling channels, but the root cause (water dripping from the tray) is often overlooked, leading to recurring issues and wasting significant debugging time and resources. Besides causing product scrap and resource waste, water contacting high-temperature metal can produce a violent "boiling over" phenomenon, causing molten metal to splash, posing a safety hazard to equipment and operators.

[0005] Impact on equipment, molds, and costs: Frequent rapid heating and cooling of the mold surface will exacerbate the thermal fatigue of the mold steel, causing cracks to appear on the mold surface and reducing the service life of the mold.

[0006] Water vapor can permeate the area around the equipment, and water droplets can cause rust on non-working surfaces of the mold, mold frame, ejector pins, sliders, and other precision components such as surrounding auxiliary equipment, increasing the equipment's failure rate and maintenance costs.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0023] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this invention. Example

[0024] Please see Figure 1 As shown, a siphon-blowing receiving tray includes a tray body 2, a receiving part 3, a water tank 4, and a water blowing mechanism 5.

[0025] The pallet body 2 is fixed to the ground, the receiving part 3 is fixed to the pallet body 2, the soaking tank is connected to the pallet body, and the blowing mechanism is connected to the soaking tank.

[0026] The tray body 2 includes a hydraulic cylinder lifting mechanism, a motor reducer rotation mechanism, a multi-link mechanism, etc., to realize lifting, swinging in and out actions during the material picking and wetting process, and to remove the casting from the differential pressure casting machine 1 to the water tank 4 for cooling of the casting 6. Figure 2 , 3 As shown in Figures 4 and 5.

[0027] like Figure 6 , Figure 7 As shown, the receiving part 3 includes an extension arm structure 301, a receiving tray 302, a water receiving tray 303, a tray connector 304, and a Teflon sleeve 305 for impact protection. The receiving tray 302 is fixed to the tray connector 304 with bolts. The tray connector 304 is inserted into the central hole of the extension arm structure 301. During use, the receiving tray 302 can rotate. The water receiving tray 303 is fixed to the receiving tray 302 with U-bolts and is responsible for collecting water. The Teflon sleeve 305 is fitted onto the receiving tray 302 before welding. The receiving tray mainly supports the casting 6 and is connected to the extension arm structure through the tray connector. The Teflon sleeve 305 protects the casting from impact damage.

[0028] like Figure 8 As shown, the extendable arm structure 301 is assembled and welded from an extendable arm 3011, a water collection tray 3012, a siphon pipe 3013, and a water-blocking edge 3014. The extendable arm 3011 is connected to the water collection tray 3012, the siphon pipe 3013 is disposed inside the water collection tray 3012, and the water-blocking edge 3014 is disposed on the inner wall of the water collection tray 3012.

[0029] After the entire pallet rises from the cooling water, the water in the water tray and the water collected in the water collection tray 3012 can be discharged into the soaking tank 4 through the siphon pipe 3013. Some water can remain in the water collection tray 3012, which has a certain depth to ensure that the water does not overflow during the material receiving process. In addition, the water-blocking edge plays a role in preventing the water in the water collection tray 3012 from splashing out during the pallet material receiving process.

[0030] When casting 6 is cooled by water, the tray receiving part 3 is immersed in the water tank 4 together with casting 6. When it is raised after cooling, the water in the receiving tray 302 and the water collected in the water receiving tray 303 are discharged into the water tank 4 through the siphon structure (a siphon is a physical phenomenon that uses the difference in liquid level and atmospheric pressure to allow liquid to flow automatically from a container at a higher position to a container at a lower position through a pipe filled with liquid). The residual water in the receiving tray 302, the anti-smashing Teflon sleeve 305, etc. will drip into the water collection tray 3012. When waiting for the position, the bottom of the water collection tray 3012 is blown. When the tray receiving part 3 enters the differential pressure casting machine 1 to receive materials again, it can be ensured that no water drips into the high temperature mold cavity.

[0031] In one specific embodiment, the hydraulic cylinder lifting mechanism is fixed on the slider seat of the base of the pallet body part 2. The lifting action is completed by the pull rod type hydraulic cylinder. The hydraulic cylinder has a large output force and a stable structure. The lifting process is guided by the linear guide rail and the slider, which has high precision, stability and reliability.

[0032] In one specific embodiment, the motor reducer rotation mechanism is driven by a servo motor to provide rotational power output. The entire mechanism is fixed on the hydraulic cylinder lifting mechanism. The motor structure is stable and reliable, with servo control, high precision, and convenient setup.

[0033] In one specific embodiment, the multi-link mechanism is fixed to the rotating mechanism via couplings, bearings, etc. The multi-link mechanism has a fixed path, small rotation space, and is easy and quick to adjust. The main body primarily realizes stable lifting, lowering, and swinging-in / out actions during material handling and wetting processes, removing the casting from inside the differential pressure press to the soaking tank for casting cooling.

[0034] In one specific embodiment, the water blowing mechanism 5 is composed of a pneumatic angle seat valve, connector fittings, etc. When the receiving tray 302 is waiting to receive materials, it automatically controls the small water droplets that accumulate at the bottom of the water collection tray through electrical program control. The overall structure can ensure that no water droplets fall into the mold cavity when the parts are picked up.

[0035] This invention improves product quality, increases production efficiency, and ensures on-site safety. It significantly enhances production continuity and provides strong support for achieving less-manned and automated differential pressure casting production. The extension arm structure 301 is an integrally welded structure, ensuring overall structural strength, compact space, and a sealed water tray.

[0036] This invention employs a simple siphon principle to ensure that no water droplets fall into the mold cavity when the pallet receives the material, thereby improving product quality and mold life, increasing production efficiency, and ensuring on-site safety. It is highly efficient and stable, low in cost, and has a robust and durable structure, making it suitable for complex production environments in differential pressure casting.

Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
