Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and more specifically, to a feeding mechanism for casting automotive parts. Background Technology

[0002] The feeding mechanism for automotive parts casting is a core piece of equipment for accurately conveying materials such as molten metal and molding sand. It is widely used in casting production lines for key automotive parts such as cylinder blocks and crankshafts. This mechanism is compatible with both small-batch manual operation and large-scale production linkage, and is a key piece of equipment for balancing casting efficiency and economy.

[0003] For example, Chinese Patent Publication No. CN202323563703.9 discloses a feeding mechanism for casting automotive parts, which includes a base. A lower mold is mounted on the upper surface of the base, and an upper mold is mounted on the upper surface of the base. The upper mold is located above the lower mold, and a connecting seat is mounted on the upper surface of the upper mold. A feeding pipe is connected to the side wall of the lower mold. A preheating structure is provided inside the lower mold. The preheating structure includes a preheating cavity, which is opened in the side wall of the lower mold. An electric heating plate is slidably connected to the inner wall of the preheating cavity, and a transmission belt is fixedly connected to the surface of the electric heating plate. This utility model, by setting a preheating structure, can preheat the lower mold before injecting raw materials into it, thereby preventing the raw materials from cooling too quickly during the injection process and affecting the quality of the cast motor housing, thus improving the practicality of the casting mold.

[0004] However, in the above-mentioned technical solutions, the traditional feeding method is direct pouring or simple pipeline transportation. This method mostly adopts manual control or simple volume measurement. The feeding amount depends on the operator's experience and judgment, which makes it difficult to guarantee the measurement accuracy. There is a problem of inaccurate feeding amount control. Especially when producing multiple varieties and small batches of castings, the existing equipment lacks a compensation mechanism for the impact of pipeline volume, resulting in poor consistency between different batches of products.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 1 and Figure 2 As shown, a feeding mechanism for casting automotive parts includes a base 1 and a lower mold 2 disposed on the base 1. The side wall of the lower mold 2 is connected to a feeding pipe 3. The end of the feeding pipe 3 away from the lower mold 2 is connected to a transition pipe 4. A metering cylinder 5 is disposed on the transition pipe 4. The metering cylinder 5 and the transition pipe 4 are connected by a flange 6. The volume calibration of the metering cylinder 5 includes the volume factor of the transition pipe 4. A piston 7 is disposed inside the feeding pipe 3. A pusher 8 is disposed on one end of the piston 7. The pusher 8 and the feeding pipe 3 form a sealed sliding fit. A hydraulic rod 9 is fixedly disposed on the end of the pusher 8 away from the piston 7. A mounting plate 10 is fixedly disposed on one side of the base 1. A heating assembly 11 is disposed between the mounting plate 10 and the lower mold 2.

[0017] like Figure 3 As shown, in another embodiment of the present invention, the heating component 11 includes a component frame 1101, the component frame 1101 is fixedly connected to the base 1 by bolts 1102, a base plate 1103 is fixedly disposed on the component frame 1101, a through groove 1104 is provided on one side above the component frame 1101, and an electric heating wire 1105 is fixedly installed on one side above the base plate 1103; The metering cylinder 5 is heated by the heating wire 1105 to ensure that the metal raw material maintains a suitable temperature during the metering process, prevents the raw material from solidifying too early, and ensures the smoothness of the feeding process and the quality of the casting. At the same time, since the component frame 1101 is fixedly connected to the base 1 by bolts 1102, the heating component 11 can be removed when the metering cylinder 5 is replaced, making it convenient to replace the metering cylinder 5.

[0018] The working principle of a feeding mechanism for casting automotive parts: During operation, molten metal raw material first enters the metering cylinder 5. The hydraulic rod 9 drives the pusher 8 and piston 7 to move away from the lower mold 2, releasing the seal of piston 7 at the outlet of the transition pipe 4, allowing the metal raw material in the metering cylinder 5 to enter the feeding pipe 3 through the transition pipe 4. Subsequently, the hydraulic rod 9 pushes the pusher 8 and piston 7 towards the lower mold 2, pressing the precisely metered metal raw material into the cavity of the lower mold 2 through the feeding pipe 3. During this process, the metering cylinder 5 adopts a modular design, and it is detachably connected to the transition pipe 4 via flange 6. Metering cylinders of appropriate volume can be quickly replaced according to the specifications of different casting products. During manufacturing, metering cylinders of various specifications... The volume factor of the transition tube 4 has been taken into account and pre-calibrated to ensure that the amount of raw material entering the lower mold 2 is accurate. This greatly improves the equipment's adaptability to different production needs and its production efficiency. At the same time, the heating component 11 works continuously, and the heat generated by the heating wire 1105 heats the metering cylinder 5 evenly through the channel 1104. This ensures that the metal raw material maintains a suitable temperature during metering and conveying, prevents the raw material from solidifying too early, and ensures the smoothness of the feeding process and the quality of the casting. This achieves accurate and flexible control of the feeding amount in the casting process of automotive parts, and is particularly suitable for flexible production modes with multiple varieties and small batches, effectively improving the product qualification rate.

[0019] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
