Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing, and in particular to an adjustable casting mold for automotive parts production and processing. Background Technology

[0002] In the manufacturing and processing of automotive parts, casting technology is widely used to form metal or non-metal parts with complex structures and high precision requirements. As the core tooling in the forming process, the structural design and performance of casting molds directly determine the forming quality, production efficiency, and production cost of the parts.

[0003] Currently, common automotive component casting molds typically consist of an upper mold and a lower mold. When these two molds are closed, they form a molding cavity that matches the shape of the part. Molten metal, resin, or low-melting-point alloys are injected into the molding cavity, and after cooling and solidification, the mold is opened to remove the part. However, existing casting molds often suffer from several drawbacks in practical applications: inconvenient adjustment of movable blocks, poor adaptability, difficulty in accurately compensating for dimensions or wear; inaccurate molding temperature control, lack of multi-point independent temperature adjustment capabilities, easily leading to poor filling of the mold material and internal defects; independent operation of heating and cooling systems with insufficient coordination, affecting both part quality and reducing production efficiency; difficulty in demolding, with traditional ejection methods easily damaging parts or the mold; and insufficient mold closing accuracy and sealing, easily causing overflow or dimensional deviations after repeated use.

[0004] Therefore, developing an adjustable casting mold that can achieve adjustable block position, precise control of molding temperature, coordinated heating and cooling, smooth demolding, and high mold closing accuracy is of great significance for improving the production quality and efficiency of automotive parts.

[0025] like Figures 1 to 4 As shown in the figure, an adjustable casting mold for manufacturing and processing automotive parts provided by an embodiment of the present invention includes a first mold 100 and a second mold 200, a movable block assembly 400 and a heating assembly 500. A forming cavity 300 is formed between the first mold 100 and the second mold 200. The movable block assembly 400 is installed in the forming cavity 300 through the first mold 100 or the second mold 200, and the mold material is formed by cooperating with the forming cavity 300 through the movable block assembly 400. The heating assembly 500 is disposed on the first mold 100 and the second mold 200, and the heating assembly 500 heats the forming cavity 300, so that the mold material is heated and formed.

[0026] By incorporating detachable or adjustable movable block components 400, the mold can quickly adapt to the molding requirements of different parts, reducing mold change costs and improving production flexibility. Simultaneously, heating components 500 are installed on the first mold 100 and the second mold 200, enabling direct and active heating of the molding cavity 300. This ensures the mold material is filled and cured in a uniform and stable temperature field, effectively improving material flowability, reducing defects such as cold shuts and shrinkage cavities, and enhancing the internal quality and dimensional accuracy of the parts. Furthermore, the heating components 500 focus on the molding cavity 300, reducing heat loss and shortening the preheating and molding cycle, thus improving production efficiency while reducing energy consumption. The overall structure is compact, facilitating integration or modification on existing equipment, and possesses excellent industrial practicality and promotional value.

[0027] In this embodiment of the application, the first mold 100 and / or the second mold 200 are provided with a movable block mounting groove 310, the movable block assembly 400 is detachably embedded in the movable block mounting groove 310, and a shim 320 or a threaded adjustment member is provided between the movable block assembly 400 and the movable block mounting groove 310 for adjusting the axial position of the movable block assembly 400.

[0028] In the above structure, to adjust the axial extension length of the movable block assembly 400 within the molding cavity 300, multiple metal shims 320 of different thicknesses are provided between the movable block assembly 400 and the bottom surface of the movable block mounting groove 310. The axial position of the movable block assembly 400 can be changed by selecting different combinations of shims 320 thicknesses. Alternatively, a threaded adjusting component can be used. A threaded hole is provided at the bottom of the movable block mounting groove 310, and an adjusting bolt is used. Tightening the adjusting bolt causes its end to push against the bottom surface of the movable block assembly 400, thereby finely adjusting the extension amount of the movable block assembly 400. This design allows for quick compensation of dimensional deviations without replacing the entire movable block 430, improving the versatility and ease of adjustment of the mold.

[0029] In this embodiment, the movable block assembly 400 includes a pusher 410, a heating element 420, and a movable block 430. The pusher 410 is provided with a guide 411, and the pusher 410 is movably mounted on the first mold 100 or the second mold 200 through the guide 411. The heating element 420 is disposed on the pusher 410, and the heating element 420 enters the molding cavity 300 through the movable block mounting groove 310. The movable block 430 is sleeved outside the heating element 420, and the movable block 430 heats the molding cavity 300 through the heating element 420.

[0030] In the above structure, the heating element 420 is fixedly mounted on the pusher 410 and moves together with the pusher 410. When the movable block assembly 400 is embedded in the movable block mounting groove 310, the heating element 420 extends into the molding cavity 300 through the movable block mounting groove 310. The movable block 430 is sleeved on the outside of the heating element 420, and the outer surface of the movable block 430 forms part of the molding cavity 300. During operation, the heating element 420 is energized and generates heat, which is transferred to the mold material in the molding cavity 300 through the movable block 430, achieving localized heating. This structure integrates the heating function with the movable block 430, improving heat transfer efficiency. At the same time, the pusher 410 drives the heating element 420 and the movable block 430 to move as a whole, facilitating subsequent demolding operations.

[0031] The heating element 420 and the movable block 430 are either interference-fitted or filled with a heat-conducting medium to ensure heat transfer efficiency.

[0032] In this embodiment of the application, the pusher 410 is provided with a push rod 440 at one end away from the movable block 430. The push rod 440 is connected to a linear drive mechanism, which is used to drive the pusher 410 to move into the molding cavity 300 after the mold material is formed.

[0033] In the above structure, the push rod 440 passes through the mold body and is connected to a linear drive mechanism. After the mold material is heated and cooled to a demoldable state, the linear drive mechanism is activated, driving the push rod 440 to move forward. The push rod 440 drives the pusher 410, the heating element 420 and the movable block 430 to move together into the molding cavity 300.

[0034] In this embodiment, the linear drive mechanism is a servo electric cylinder or a hydraulic cylinder. The linear drive mechanism is interlocked with the controller of the heating element 420 so that the ejection action is automatically started after the heating element 420 stops heating and the mold material cools down to a preset temperature.

[0035] Furthermore, in order to ensure the smooth movement of the push rod 440 during reciprocating motion and to prevent the mold material or external impurities from entering the mold and affecting the molding accuracy, a sealing element and a guide sleeve are provided between the push rod 440 and the mating hole of the first mold 100 or the second mold 200.

[0036] In the above structure, the linear drive mechanism and the controller of the heating component 500 are interlocked through a PLC or microcontroller. The controller monitors the temperature of the molded material inside the molding cavity 300 in real time through a temperature sensor. When the heating element 420 stops heating and the molded material temperature cools naturally or is forced to cool to the preset safe demolding temperature, the controller automatically sends a start signal to the linear drive mechanism, driving the pusher 410 to eject the part. This interlocking setting avoids deformation or sticking of parts due to forced ejection when the temperature is too high, and also prevents the production cycle from being extended due to premature cessation of cooling, thus realizing fully automatic cycle control of molding-cooling-demolding.

[0037] In this embodiment, the heating assembly 500 includes multiple independently controlled heating rods 510, which are respectively arranged inside the first mold 100 and the second mold 200 and distributed along the contour of the molding cavity 300. The first mold 100 and the second mold 200 also include at least one temperature sensor and a controller. The temperature sensor is used to detect the temperature in different areas of the molding cavity 300, and the controller receives the signal from the temperature sensor and adjusts the power of each group of heating rods 510 to keep the temperature field in the molding cavity 300 uniform.

[0038] In the above structure, multiple heating rods 510 are densely distributed along the contour of the molding cavity 300. Multiple temperature sensors within the first mold 100 and the second mold 200 are respectively arranged in different areas of the molding cavity 300. All temperature sensor signals are connected to a controller. The controller compares the temperature values ​​fed back by each sensor with the target value and adjusts the output power of each group of heating rods 510 accordingly, so that the temperature in different areas of the molding cavity 300 tends to be uniform. For example, when the temperature in a certain area is too low, the duty cycle of the corresponding heating rod 510 is increased; when the temperature is too high, the power is reduced.

[0039] In this embodiment of the application, the heating assembly 500 further includes a heating distribution component 520, which connects to a plurality of heating rods 510, and the heating rods 510 adjust their respective temperatures through the heating distribution component 520.

[0040] In the above structure, the heating distribution component 520 has multiple independent channels or circuits, each corresponding to a heating rod 510. The controller delivers current of different power to each heating rod 510 through the heating distribution component 520, thereby realizing independent temperature adjustment of each heating rod 510. This structure concentrates the complex power distribution circuitry into one component, reducing external wiring and facilitating maintenance and replacement.

[0041] In this embodiment, the heating distribution component 520 includes a distribution block 521, which contains a plurality of mutually isolated heating circuits. Each heating circuit is connected to a heating rod 510. Each heating circuit is connected in series with an independent proportional regulating valve 530, which is electrically connected to the controller and is used to independently adjust the heating power of the corresponding heating rod 510 according to the signal from the temperature sensor.

[0042] The proportional regulating valve 530 adjusts the input current of the corresponding heating circuit according to the control signal output by the controller, so as to achieve precise power control of a single heating rod 510, avoid temperature differences in different areas of the molding cavity 300, ensure uniform filling and flow of the mold material, and reduce defects such as shrinkage cavities and deformation caused by uneven temperature in the parts.

[0043] In this embodiment, both the first mold 100 and the second mold 200 are provided with cooling channels. An electrically controlled shut-off valve is provided at the inlet of the cooling channel. The electrically controlled shut-off valve is linked to the controller of the heating component 500. During the mold preheating and molding stage, the controller keeps the electrically controlled shut-off valve closed. When the mold material is molded and demolding is required, the controller opens the electrically controlled shut-off valve and introduces the cooling medium.

[0044] This structure can flexibly adjust the cooling rhythm according to the actual forming stage of the casting mold. During the heating and forming stage, it avoids the cooling medium from continuously carrying away heat, ensuring that the temperature within the forming cavity 300 is kept stable within the preset range, which is conducive to improving the forming quality of the casting. After forming, the cooling medium is quickly introduced to carry away the overall heat, shortening the cooling and setting time of the casting and improving the production efficiency.

[0045] In this embodiment of the application, the outer surfaces of both the first mold 100 and the second mold 200 are covered with a heat insulation layer.

[0046] In the above structure, the heat insulation layer can be made of aerogel felt, ceramic fiber cloth, or microporous calcium silicate board, with a thickness of 5-20 mm. The heat insulation layer is fixed to the outer surface of the mold by high-temperature resistant adhesive or metal strapping. The above-disclosed embodiments are only a few specific examples of the present invention; however, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
