Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to a molding die for an automotive engine oil pan. Background Technology

[0002] The oil pan of a car engine is located at the bottom of the engine and is usually made of metal. Its main purpose is to store engine lubricating oil, providing stable lubrication for the engine. At the same time, the oil pan helps to dissipate heat from the lubricating oil and settle impurities. Through its tight connection with the engine block and its cooperation with the oil pump, it ensures that the lubricating oil flows smoothly in the engine. The oil pan is an important component of the car engine and plays a key role in the reliable operation of the engine.

[0003] Automotive engine oil pan forming mold is a special tool used to manufacture automotive engine oil pans. It is usually made of high-strength materials and has a precise cavity and structure. The oil pan of the required shape is formed by processing inside the mold. The mold is precisely designed to ensure that the oil pan is dimensionally accurate and has a smooth surface, thereby improving product quality and production efficiency. It is an indispensable and important piece of equipment in automobile manufacturing.

[0004] Traditional molds typically employ an integral structure, allowing ejection only from a single direction during demolding. This can easily lead to the oil pan getting stuck inside the mold. The lack of an effective separation structure results in significant friction between the parts and the mold during demolding, causing surface scratches, deformation, and other quality issues, thus reducing the product yield. To address these problems, a new automotive engine oil pan molding mold is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a molding die for an automotive engine oil pan, which aims to improve the problem of the lack of an effective separation structure in traditional molds in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A molding die for forming an oil pan for an automobile engine includes a control console. A lower die is slidably connected to the top of the control console, and an upper die is slidably connected to the top of the lower die. A control mechanism is provided inside the control console. An ejection assembly is provided on the top of the control mechanism. Limiting assemblies are provided on both the front and rear sides of the control mechanism. A cooling mechanism is provided on the outer periphery of the lower die and the upper die. Two disassembly assemblies are provided on both the front and rear sides of the cooling mechanism.

The tops of the two movable blocks are respectively fixedly connected to the bottom left and right sides of the lower mold.

[0009] As a further description of the above technical solution:

The lower mold 2 is composed of left and right parts that can be separated and merged. The lower mold 2 and the upper mold 3 are used for extrusion molding. Positioning rods 4 are fixedly connected to the left and right sides of the top of the lower mold 2. The two positioning rods 4 are slidably connected to the left and right sides inside the upper mold 3, respectively. The positioning rods 4 are used to determine the accuracy of the merging of the lower mold 2 and the upper mold 3, so that the lower mold 2 and the upper mold 3 can be guaranteed not to deviate from the merging.

[0035] The control mechanism 5 includes an electric push rod 501, which is fixedly connected to the bottom of the control console 1. A slider 502 is fixedly connected to the top of the electric push rod 501. The electric push rod 501 is connected to the slider 502. The slider 502 is moved by activating the electric push rod 501. The electric push rod 501 is a short-stroke electric push rod, model La12. Moving blocks 503 are fixedly connected to both sides of the slider 502. Rotating rods 504 are connected to the inside of the two moving blocks 503. Movable blocks 505 are rotatably connected to the ends of the two rotating rods 504 away from the two moving blocks 503. The rotating rods 504 are used to connect the moving blocks 503 and the movable blocks 505. When the moving blocks 503 move, the rotating rods 504 can rotate, thereby controlling the movement of the movable blocks 505. The tops of the two movable blocks 505 are fixedly connected to the bottom left and right sides of the lower mold 2, respectively. The two movable blocks 505 are connected to the left and right sides of the lower mold 2, thereby allowing the lower mold 2 to separate left and right.

[0036] Reference Figure 1 and Figure 4The cooling mechanism 8 includes a protective frame 805, which is slidably connected to the outer periphery of the lower mold 2 and the upper mold 3. A cooler 801 is fixedly connected to the left side of the protective frame 805. The cooler 801 is composed of a stainless steel water circulation pump with a cooling capacity of 2.85 kW. Cooling pipes 802 are fixedly connected to both ends of the cooler 801. The cooling pipes 802 contain coolant for providing circulating cooling. Fans 803 are fixedly connected to both the front and rear sides of the protective frame 805. Filter plates 804 are slidably connected to opposite sides of the two fans 803. The fans 803 are used to control the generation of airflow. The airflow can form a cold airflow after passing through the cooling pipes 802. The filter plates 804 are used to prevent impurities from entering the protective frame 805.

[0037] Reference Figure 3 The ejector assembly 6 includes an ejector rod 601, which is fixedly connected to the top of the slider 502. A top plate 602 is fixedly connected to the top of the ejector rod 601, and the top plate 602 is slidably connected to the bottom of the lower mold 2. The ejector rod 601 is used to connect the top plate 602 and the slider 502. When the slider 502 moves, it can drive the top plate 602 to move together, thereby ejecting the oil pan.

[0038] Reference Figure 5 The disassembly assembly 9 includes a lever 901, which is slidably connected to the front side of the cooling mechanism 8. A rod 902 is fixedly connected to one side of the lever 901. The lever 901 is connected to the rod 902, and when the lever 901 moves, it can drive the rod 902 to move together. A spring 904 is fixedly connected to the end of the lever 901 away from the rod 902. A slide rod 903 is slidably connected between the rod 902 and the inside of the lever 901. The slide rod 903 is used to guide the rod 902 to move. The spring 904 provides elastic support and reaction force. The control panel 1 has a sliding groove 905 inside, and the filter plate 804 has a slot 906 inside. The lever 901 is slidably connected inside the sliding groove 905. The sliding groove 905 provides movement space for the lever 901. The insertion rod 902 is slidably connected inside the slot 906. The slot 906 is used to cooperate with the insertion rod 902. By inserting the insertion rod 902 into the slot 906, the filter plate 804 can be limited.

[0039] Reference Figure 3 The limiting component 7 includes a limiting block 701, which is fixedly connected to one side of the movable block 505. Limiting grooves 702 are provided on both the front and rear sides of the control console 1. The limiting block 701 is slidably connected inside one of the limiting grooves 702. The limiting groove 702 is used to cooperate with the limiting block 701. By allowing the limiting block 701 to slide in the limiting groove 702, the movable block 505 can always maintain horizontal movement.

[0040] Working principle: When processing the oil pan, the electric push rod 501 is started first. The electric push rod 501 controls the slider 502 to move upward. When the slider 502 moves upward, the push rod 601 and the top plate 602 move accordingly, and the rotating rods 504 inside the two moving blocks 503 rotate in opposite directions, thereby controlling the two movable blocks 505 to move in opposite directions. The limiting block 701 will move along the limiting groove 702 when the movable block 505 moves, thereby causing the left and right parts of the lower mold 2 to move in opposite directions. Then the oil pan is placed on the top plate 602. After that, the electric push rod 501 is started, which controls the slider 502 to move downward. When the slider 502 moves, the two rotating rods 504 rotate relative to each other, thereby causing the two movable blocks 505 to move towards each other. Then the left and right parts of the lower mold 2 are merged, and the ejector assembly 6 moves downward, so that the oil pan is located inside the lower mold 2.

[0041] Then, the upper mold 3 descends and merges with the lower mold 2 to complete the mold processing. After the mold processing, the protective frame 805 descends, and then the cooler 801 is started. The cooler 801 begins to cool the refrigerant in the cooling pipe 802. Then the fan 803 is started to make the air flow. After passing through the cooling pipe 802, cold air is formed, which can quickly cool the oil pan.

[0042] After cooling is complete, the lower mold 2 is separated from the upper mold 3. The electric push rod 501 can then be restarted to control the slider 502 to move upward. The separation movement at both ends of the lower mold 2 causes the push rod 601 to drive the top plate 602 to move upward, thereby causing the oil pan to rise out of the lower mold 2 and the mold to be removed.

[0043] After the work is completed, the filter plate 804 needs to be cleaned. By moving the lever 903 to the lever 901, the lever 901 moves the insert rod 902 together. When the lever 901 moves, it can squeeze the spring 904. After the insert rod 902 slides out of the slot 906 opened inside the filter plate 804, the filter plate 804 can be taken out from the protective frame 805.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
