Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy mold technology, specifically to an aluminum alloy mold with a temperature regulating structure. Background Technology

[0002] Aluminum alloy molds are tools made from aluminum alloy as the core material, used for forming and processing various products. They are widely used in industrial production. Through specific structural designs, they shape raw materials (such as metals, plastics, and rubber) into products that meet expected shapes and sizes under pressure, temperature, and other conditions. They combine the advantages of aluminum alloy, such as lightweight, good thermal conductivity, and ease of processing, with the structural strength and durability required for molds, making them one of the important forming equipment in modern manufacturing.

[0003] For example, Chinese utility model patent with publication number "CN219130696U" discloses an aluminum alloy cover plate mold. This utility model utilizes an adjustment component and a pushing component. The distance between the bottom of the upper mold base and the bottom of the lower mold base, as well as the distance between the inner sidewall of the upper mold base and the inner sidewall of the lower mold base, can be adjusted using a first electric telescopic rod and a second electric telescopic rod. It can manufacture aluminum alloy cover plates of various sizes according to actual needs. Under the action of the elastic properties of the spring, the push plate will be pushed to move, causing the aluminum alloy cover plate to fall off, which is convenient for the aluminum alloy cover plate to be unloaded and has high working efficiency.

[0004] The aforementioned existing technology has the following shortcomings in actual implementation: although it facilitates the cutting of aluminum alloy cover plates, it is impossible to cool the mold in a timely manner during use, making temperature regulation more difficult. Utility Model Content

[0005] One of the technical problems this application aims to solve is that although existing aluminum alloy molds have the advantage of being easy to cut materials, they lack a structure that can monitor the mold temperature in real time and efficiently dissipate heat during use. This makes it difficult to cool the mold in a timely manner, which in turn makes it difficult to regulate the mold temperature and affects production efficiency and product consistency.

[0006] To address the aforementioned technical problems, this application provides an aluminum alloy mold with a temperature-regulating structure, including a shell, wherein a temperature-regulating mechanism is disposed inside the shell, and the temperature-regulating mechanism includes:

[0007] The lower mold is fixedly connected to the inside of the outer shell;

[0008] A flow channel is formed between the outer shell and the lower mold;

[0009] An isolation cylinder is fixedly connected to the front and rear sides of the lower mold.

[0010] Temperature sensors are fixedly installed on the front and rear sides of the lower mold.

[0011] In some embodiments, the isolation cylinder is disposed inside the flow channel, and the temperature sensor is disposed inside the isolation cylinder.

[0012] In some embodiments, a flow guiding mechanism is provided on the outer side of the housing, the flow guiding mechanism comprising:

[0013] An inlet water pipe is fixedly connected to one side of the outer casing;

[0014] The first valve is installed inside the inlet water pipe;

[0015] Water outlet pipe, which is fixedly connected to the other side of the outer casing;

[0016] The second valve is installed inside the output water pipe.

[0017] In some embodiments, the housing is provided with a sealing mechanism, the sealing mechanism comprising:

[0018] The slot is formed on the upper surface of the outer shell and the lower mold;

[0019] A cover plate, which is fixedly connected to the inside of the slot by screws;

[0020] The first guide groove extends through the interior of the cover plate;

[0021] A guide post, wherein the guide post is disposed inside the first guide groove and is slidably connected to the first guide groove;

[0022] The upper mold is fixedly connected to the upper side of the guide post;

[0023] A sealing plate is fixedly connected to the lower side of the upper mold.

[0024] In some embodiments, a connecting mechanism is provided on the upper side of the sealing mechanism, the connecting mechanism comprising:

[0025] A fixed column is fixedly connected to the upper side of the upper mold;

[0026] A flange, which is fixedly connected to the upper side of the fixed column.

[0027] In some embodiments, stabilizing mechanisms are provided on both sides of the housing, the stabilizing mechanisms including:

[0028] A connecting plate, which is fixedly connected to both sides of the outer casing;

[0029] A mating groove, which extends through the interior of the connecting plate;

[0030] The docking post is disposed inside the docking groove and slidably connected to the docking groove, and the docking post is fixedly connected to the lower side of the upper mold.

[0031] In some embodiments, an anti-slip mechanism is provided on the lower side of the housing, the anti-slip mechanism comprising:

[0032] A rubber pad, which is fixedly connected to the lower side of the outer casing;

[0033] Anti-slip grooves are formed on the lower surface of the rubber pad.

[0034] This utility model has at least the following beneficial effects:

[0035] A flow channel is formed around the outer shell and the lower mold, creating a large-area heat exchange channel. The heat generated by the lower mold during the molding process can be quickly transferred to the flow channel, preventing heat from accumulating inside the mold and alleviating the problem of "untimely cooling" from the source. This lays the foundation for the subsequent cooling intervention of the flow guiding mechanism. The temperature control mechanism, through the combination of "sensor monitoring + flow channel heat conduction", can not only capture the temperature changes of the mold in real time, but also quickly dissipate heat. Together with the flow guiding mechanism, it can achieve dynamic adjustment of "rapid cooling when the temperature exceeds the standard and stable heat preservation when the temperature reaches the standard".

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please see Figures 1-5 This utility model provides a technical solution: an aluminum alloy mold with a temperature regulating structure, including a shell 1, and a temperature regulating mechanism is provided inside the shell 1. The temperature regulating mechanism includes:

[0044] The lower mold 101 is fixedly connected to the inside of the outer shell 1;

[0045] A flow channel 102 is formed between the outer shell 1 and the lower mold 101;

[0046] The isolation cylinder 103 is fixedly connected to the front and rear sides of the lower mold 101;

[0047] Temperature sensor 104 is fixedly installed on the front and rear sides of the lower mold 101; isolation cylinder 103 is disposed inside the flow channel 102, and temperature sensor 104 is disposed inside the isolation cylinder 103.

[0048] Through the above technical solution, the lower mold 101, as the molding core, is in direct contact with the high-temperature raw materials, and the heat generated by it can be quickly diffused through the flow groove 102 between it and the outer shell 1. The isolation cylinder 103 is located inside the flow groove 102, which not only avoids the monitoring error caused by the direct impact of the cooling medium such as cooling water on the temperature sensor 104, but also allows the sensor to be close to the surface of the lower mold 101 to ensure the accuracy of the collected temperature data. The temperature sensor 104 provides real-time feedback of temperature signals, providing a basis for the start and stop of the subsequent flow guiding mechanism, forming a pre-temperature control foundation of "temperature monitoring-heat conduction", and avoiding the accumulation of heat inside the mold.

[0049] Please see Figures 1-5 The outer side of the outer casing 1 is provided with a flow guiding mechanism, which includes: an inlet water pipe 201, which is fixedly connected to one side of the outer casing 1; a first valve 202, which is installed inside the inlet water pipe 201; an outlet water pipe 203, which is fixedly connected to the other side of the outer casing 1; and a second valve 204, which is installed inside the outlet water pipe 203.

[0050] Through the above technical solution, a controllable cooling medium circulation system is constructed, which, together with the temperature control mechanism, achieves precise cooling: the input water pipe 201 is connected to external cooling equipment (such as a chiller) to stably deliver the cooling medium; the first valve 202 can be adjusted manually or electrically (e.g., the flow rate can reach 50L / min when fully open and drop to 25L / min when half open) to achieve precise control of the medium inflow rate and avoid excessively rapid cooling that could lead to excessive temperature difference in the mold; the output water pipe 203 promptly discharges the high-temperature medium after absorbing heat, forming a closed-loop circulation of "water inlet-heat absorption-drainage"; the second valve 204 is linked with the first valve 202 and can adjust the residence time of the medium in the flow channel 102 (e.g., closing the second valve to extend the residence time and improve heat absorption efficiency), ultimately achieving dynamic balance of mold temperature and solving the problem of "uncontrollable cooling" in existing technologies.

[0051] Please see Figures 1-5 The outer shell 1 is provided with a sealing mechanism, which includes: a slot 301, which is formed on the upper surface of the outer shell 1 and the lower mold 101; a cover plate 302, which is fixedly connected to the inside of the slot 301 by screws; a first guide groove 303, which is formed through the inside of the cover plate 302; a guide post 304, which is disposed inside the first guide groove 303 and slidably connected to the first guide groove 303; an upper mold 305, which is fixedly connected to the upper side of the guide post 304; and a sealing plate 306, which is fixedly connected to the lower side of the upper mold 305.

[0052] The above technical solutions ensure the accuracy and sealing of the mold during closure, thereby improving the product molding quality: the slot 301 provides a positioning reference for the cover plate 302, and the screw fixing method ensures that the cover plate is firmly installed (strong vibration resistance, avoiding loosening during molding) and facilitates disassembly and maintenance later; the first guide groove 303 and the guide post 304 form a sliding guide structure, which restricts the movement trajectory of the upper mold 305 and avoids deviation during closure (the alignment accuracy can reach ±0.02mm); the sealing plate 306 is made of high-temperature resistant rubber material (capable of withstanding temperatures above 200℃), and after being attached to the lower mold 101, it can seal the edge of the cavity, prevent the leakage of raw materials (such as molten aluminum alloy), and at the same time reduce the loss of heat from the cavity gaps, help maintain temperature stability, and solve the product defects caused by the existing mold's "misalignment during closure and poor sealing".

[0053] Please see Figures 1-5 The upper side of the sealing mechanism is provided with a connecting mechanism, which includes: a fixed column 401, which is fixedly connected to the upper side of the upper mold 305; and a flange 402, which is fixedly connected to the upper side of the fixed column 401.

[0054] The above technical solutions improve the compatibility of molds with external equipment and simplify the installation process: the fixed column 401 is made of high-strength alloy material (tensile strength ≥600MPa), which can stably bear the weight of the upper mold 305 and the pressure during molding (e.g., no deformation under 10MPa molding pressure); the flange 402 follows standard industrial interface dimensions (e.g., DN50 flange), which can be quickly connected to external drive equipment (e.g., hydraulic cylinder, servo motor) without the need for additional customized connectors, reducing equipment adaptation costs; at the same time, the rigid connection method of the flange (fastened with bolts) can transmit stable driving force, ensuring uniform pressure when the upper mold 305 moves down, avoiding mold damage due to uneven force, and solving the problem of "complex docking between existing molds and external equipment".

[0055] Please see Figures 1-5 The outer shell 1 is provided with stabilizing mechanisms on both sides. The stabilizing mechanisms include: a connecting plate 501, which is fixedly connected to both sides of the outer shell 1; a docking groove 502, which is opened through the inside of the connecting plate 501; and a docking post 503, which is disposed inside the docking groove 502 and slidably connected to the docking groove 502. The docking post 503 is fixedly connected to the lower side of the upper mold 305.

[0056] The above technical solutions enhance the stability of the mold during operation and avoid precision deviations caused by vibration: the connecting plate 501 and the outer shell 1 are welded together to form a symmetrical support structure, dispersing the lateral force when the upper mold 305 moves downward; the docking groove 502 and the docking column 503 form a secondary guide (in coordination with the guide structure of the sealing mechanism), further limiting the lateral displacement of the upper mold; the docking column 503 and the upper mold 305 are integrally formed, with high rigidity and no assembly gap, which can synchronously transmit the force of the upper mold, avoid component damage caused by local stress concentration, solve the problem of "poor stability during operation" of existing molds, and ensure product consistency during mass production.

[0057] Please see Figures 1-5 The lower side of the outer casing 1 is provided with an anti-slip mechanism, which includes: a rubber pad 601, which is fixedly connected to the lower side of the outer casing 1; and an anti-slip groove 602, which is formed on the lower surface of the rubber pad 601.

[0058] The above technical solutions improve the anti-slip performance of the mold during placement and ensure operational safety: the rubber pad 601 is made of a high-friction coefficient material, which increases the friction between the mold and the placement surface (such as a workbench), preventing mold displacement due to equipment vibration during molding (it can withstand horizontal thrust below 500N without slipping); the anti-slip groove 602 has a diamond pattern design (groove depth 2mm, spacing 5mm), which not only enhances the drainage of the rubber pad (preventing water accumulation on the table from causing slippage), but also further increases the frictional resistance; at the same time, the elastic properties of the rubber pad can buffer the vibration of the mold during operation (such as reducing the vibration frequency from 50Hz to below 20Hz), reducing damage to the placement table and solving the problem of existing molds being "easy to slip and vibrate greatly".

[0059] All electrical devices in this invention are powered by an external power source;

[0060] Working principle and usage process: First, the flange 402 of the connecting mechanism is connected to an external driving device such as a hydraulic cylinder, which drives the fixed column 401 to move the upper mold 305 downward. During the downward movement, the docking column 503 of the stabilizing mechanism slides along the docking groove 502 of the connecting plate 501, while the guide column 304 of the sealing mechanism slides along the first guide groove 303 of the cover plate 302. The double guidance ensures that the upper mold 305 and the lower mold 101 are accurately aligned until the sealing plate 306 on the lower side of the upper mold 305 fits against the lower mold 101 to form a sealed cavity and complete the mold closure.

[0061] Subsequently, raw materials such as molten aluminum alloy and plastic are injected into the sealed cavity for molding. During the process, the temperature sensor 104 of the temperature control mechanism is placed inside the isolation cylinder 103 to avoid interference from the cooling medium and monitor the temperature of the lower mold 101 in real time, and transmit the data to the control system. If the temperature exceeds the process set value, the control system triggers the flow guiding mechanism: the first valve 202 of the input water pipe 201 is opened, allowing the external cooling medium, such as cooling water, to flow into the flow channel 102 between the outer shell 1 and the lower mold 101 through the input water pipe 201. When the medium flows in the flow channel 102, it absorbs the heat of the lower mold 101 and then discharges it through the second valve 204 of the output water pipe 203, forming a "water inlet-heat absorption-drainage" cycle of cooling until the mold temperature drops to the target range. If the temperature reaches the target, the valve opening is adjusted to reduce the medium flow rate and maintain a constant temperature environment.

[0062] After molding is completed, the external drive device moves the upper mold 305 upward to reset and removes the molded product. Throughout the process, the rubber pad 601 and anti-slip groove 602 of the anti-slip mechanism on the lower side of the outer shell 1 enhance the friction between the mold and the placement surface, prevent mold displacement, and ensure stable operation.
