Description

Technical Field

[0001] This utility model relates to the technical field of aluminum casting production equipment, and in particular to a structure for temperature control of aluminum casting molds. Background Technology

[0002] In the production of aluminum castings, mold temperature control is a crucial step. The stability and uniformity of the mold temperature directly affect the forming quality, dimensional accuracy, and surface finish of the castings. Traditional mold temperature control methods often employ a single heating or cooling method, making it difficult to achieve precise temperature regulation. Furthermore, unreasonable layouts of heating and cooling systems can lead to uneven heating or cooling of the mold, thus affecting the quality of the castings.

[0003] In the prior art, Chinese patent document CN108044082A discloses a low-pressure casting mold, which consists of an upper mold, a middle mold, and a lower mold. A crucible is located at the bottom of the lower mold. An air inlet is located on the upper left side of the crucible, connected to an air inlet pipe on its left end. A liquid inlet is located on the upper right side of the crucible, connected to a liquid inlet pipe on its right end. A riser pipe is located inside the crucible, and its top end is connected to the lower mold via a gating sleeve installed at the center of the lower mold. A middle mold is located at the top of the lower mold. A cooling chamber is located in the side wall of the middle mold, surrounded by cooling pipes. A water inlet pipe is located on the upper left side of the middle mold, and a water outlet pipe is located on the lower right side of the middle mold. However, consistent with conventional techniques, the top-to-bottom cooling method makes it difficult to ensure temperature uniformity across the mold. The upper part of the mold may reach the set temperature before the lower part, or the cooling rates may be inconsistent, resulting in a temperature gradient within the mold. This uneven temperature distribution directly affects the molding quality of the casting, making it prone to defects such as deformation and cracks during the molding process, resulting in poor practicality. Therefore, this utility model discloses a structure for temperature control of aluminum casting molds to solve the problem of inconsistent mold temperature cooling rates, which leads to temperature gradients inside the mold.

[0023] This utility model provides, for example Figures 1 to 4The structure shown is for temperature control of aluminum casting molds, comprising: a mounting frame 1, a fixing frame 2 mounted on the lower middle part of the mounting frame 1, a support rod 13 mounted on the inner wall of the fixing frame 2, and a mounting rod 4 mounted on the upper inner wall of the mounting frame 1. A mold cylinder 3 is mounted on the other end of the mounting rod 4. Temperature control components are mounted on the mounting frame 1 and the support rod 13. The temperature control components include a heating system and a cooling system. The heating system is used to bring the mold to a specified high temperature, and the cooling system is used to rapidly cool the mold when the temperature is too high. This invention achieves temperature control of the mold by uniformly arraying heating and cooling pipes on the side wall of the mold cylinder. This layout ensures the uniformity of heating and cooling of various parts of the mold, effectively avoiding defects such as deformation and cracks caused by uneven temperature during the casting process.

[0024] Furthermore, in this example, such as Figure 3 and Figure 4As shown, the heating system includes a PLC controller 8, which is mounted on a fixed frame 2. A wiring harness mounting tube 9 is installed on the back side wall of the PLC controller 8, and a first heating tube 10 is installed at the other end of the wiring harness mounting tube 9. A heating tube power supply is installed on the PLC controller 8, and the wiring harness of the heating tube power supply is installed on the first heating tube 10 through the wiring harness mounting tube 9. The PLC controller 8 controls the heating tube power supply, and the PLC controller 8 and the heating tube power supply are electrically connected. Multiple sets of second heating tubes 5 are evenly arrayed on the upper end face of the first heating tube 10. The sidewall of each set of second heating tubes 5 is attached to the sidewall of the mold cylinder 3. The second heating tubes 5 are evenly arrayed on the sidewall of the mold cylinder 3. The cooling system includes a circulating water pump 11, which is mounted around a support rod 1. The circulating water pump 11 is equipped with a coolant delivery pipe 12 at its top. Multiple sets of cooling pipes 6 are installed at the top of the coolant delivery pipe 12. The middle section of each set of cooling pipes 6 is fitted against the side wall of the mold cylinder 3, and a connecting pipe 7 is installed at the top of each set of cooling pipes 6. A coolant injection pipe is installed at the other end of the circulating water pump 11, and a coolant discharge pipe is installed on one side of the connecting pipe 7. Multiple sets of heat dissipation fins are evenly arrayed on the coolant discharge pipe, and the end of the coolant discharge pipe is connected to the coolant injection pipe. A coolant tank is connected to one side of the coolant injection pipe, and a solenoid valve is installed on the coolant injection pipe. The PLC controller 8 is electrically connected to the solenoid valve and the circulating water pump 11. Before production begins, both the PLC controller 8 and the circulating water pump 11 are in standby mode. The system continuously monitors the current temperature of the mold cylinder 3 using a built-in temperature sensor and compares it with a preset target temperature range. When the mold temperature is below the preset target range, the PLC controller 8 receives a signal and activates the heating element power supply. The first heating element 10 and multiple sets of second heating elements 5 are heated via the wiring harness mounting pipe 9, and the heat is evenly distributed to the outer wall of the mold cylinder 3. The second heating elements 5 are tightly fitted to the side wall of the mold cylinder 3, rapidly transferring heat to the mold and raising its temperature to the target range. When the mold temperature reaches or exceeds the preset target range, the cooling system is activated. The PLC controller 8 controls the circulating water pump 11 and the solenoid valve to open, injecting coolant into multiple sets of cooling pipes 6 through the coolant delivery pipe 12. The cooling pipes 6 are also tightly fitted to the side wall of the mold cylinder 3, rapidly reducing the mold temperature through heat exchange. Used coolant is collected through the connecting pipe 7 and discharged through the coolant discharge pipe. During discharge, the coolant dissipates heat through multiple sets of heat dissipation fins, further improving cooling efficiency. The end of the coolant discharge pipe is connected to the coolant injection pipe, forming a closed-loop cooling system and realizing the recycling of coolant. Throughout the production process, the system continuously monitors the mold temperature and dynamically adjusts the working status of the heating and cooling systems based on the deviation between the actual temperature and the target temperature.By controlling the heating and cooling processes, the mold temperature is ensured to remain within the specified constant temperature range, thereby meeting the quality requirements for aluminum casting production.
