Description

An auxiliary structure for die casting of aluminum alloy Technical Field

[0001] This utility model relates to the field of aluminum alloy die casting technology, and in particular to an auxiliary structure for aluminum alloy die casting. Background Technology

[0002] The temperature control module is an important auxiliary structure for aluminum alloy die casting. This module consists of a coolant circulation system and a temperature sensor. The coolant pump, coolant tank and temperature regulating device in the coolant circulation system work together to deliver coolant to the coolant channel of the mold body as needed to cool the mold, playing a key role in aluminum alloy die casting.

[0003] However, in the existing technology, the temperature control of die casting molds usually adopts a fixed cooling water channel layout, which is difficult to adjust flexibly according to different die casting processes and mold structures. This results in uneven cooling effect, which affects the solidification speed and microstructure of aluminum alloys. It can also lead to increased local thermal fatigue of the mold, shorten its lifespan, increase maintenance and replacement costs, and cause defects such as dimensional deviations, deformation, or even cracks in die castings due to inconsistent shrinkage. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an auxiliary structure for aluminum alloy die casting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary structure for aluminum alloy die casting, including a die casting mold mechanism, which consists of a fixed mold assembly and a moving mold assembly. Both the fixed mold assembly and the moving mold assembly are equipped with a temperature control mechanism. The temperature control mechanism includes a liquid inlet main pipe, an adjusting branch pipe fixedly connected to the bottom of the liquid inlet main pipe, a liquid outlet main pipe fixedly connected to the bottom of the adjusting branch pipe, a control valve fixedly connected to the upper part of the adjusting branch pipe, and a temperature sensor fixedly connected to the lower part of the adjusting branch pipe. A water-cooling unit is externally connected to the temperature control mechanism.

[0006] Preferably, multiple regulating branches are fixedly connected to the bottom of the main liquid inlet pipe, and the multiple regulating branches are evenly distributed at the bottom of the main liquid inlet pipe.

[0007] Preferably, the outlet end of the water-cooled unit is fixedly connected to a No. 1 connecting pipe, which is fixedly connected to the main inlet pipe.

[0008] Preferably, the inlet end of the water-cooled unit is fixedly connected to a No. 2 connecting pipe, which is fixedly connected to the outlet main pipe.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] 1. In this utility model, the coolant inlet flow rate is flexibly adjusted based on the detection data of the temperature sensor. The temperature sensor is installed at the lower part of the regulating branch pipe and can monitor the coolant temperature in real time after heat absorption. When the local temperature of the die-casting mold mechanism is too high, the coolant temperature in the corresponding regulating branch pipe increases, the temperature sensor feeds back the data, and the valve controls the valve to reduce the inlet flow rate; conversely, the inlet flow rate increases. This ensures that the cooling rate and temperature of the fixed mold assembly, the moving mold assembly, and the raw materials inside them remain uniform, effectively avoiding the problem of inconsistent solidification speed and poor microstructure properties of aluminum alloy caused by uneven mold temperature. It reduces the probability of defects such as shrinkage cavities and deformation in die-cast parts, improves the forming quality and dimensional accuracy of die-cast parts, extends the service life of die-casting molds, reduces production losses and costs caused by improper mold temperature control, and significantly improves the efficiency and benefits of aluminum alloy die-casting production.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example: As shown in Figures 1-4, this utility model provides an auxiliary structure for aluminum alloy die casting, including a die casting mold mechanism 1. The die casting mold mechanism 1 consists of a fixed mold assembly 11 and a moving mold assembly 12. Both the fixed mold assembly 11 and the moving mold assembly 12 are equipped with a temperature control mechanism 2. The temperature control mechanism 2 includes a liquid inlet main pipe 21, an adjusting branch pipe 22 fixedly connected to the bottom of the liquid inlet main pipe 21, a liquid outlet main pipe 23 fixedly connected to the bottom of the adjusting branch pipe 22, and a control valve fixedly connected to the upper part of the adjusting branch pipe 22. A temperature sensor 25 is fixedly connected to the lower part of the valve 24 and the regulating branch pipe 22. The temperature control mechanism 2 is externally connected to the water-cooled unit 3. Multiple regulating branch pipes 22 are fixedly connected to the bottom of the liquid inlet main pipe 21. The multiple regulating branch pipes 22 are evenly distributed at the bottom of the liquid inlet main pipe 21. The liquid outlet end of the water-cooled unit 3 is fixedly connected to the No. 1 connecting pipe 4, which is fixedly connected to the liquid inlet main pipe 21. The liquid inlet end of the water-cooled unit 3 is fixedly connected to the No. 2 connecting pipe 5, which is fixedly connected to the liquid outlet main pipe 23.

[0019] The specific setup and function of this embodiment are described below. The die-casting mold mechanism 1, as the core forming component, consists of a fixed mold assembly 11 and a moving mold assembly 12. These two components work together to form a die-casting cavity for die-casting aluminum alloy materials. The temperature control mechanism 2 plays a crucial role within the fixed mold assembly 11 and the moving mold assembly 12. Its main inlet pipe 21 receives coolant from the water-cooled unit 3 and is connected via a first connecting pipe 4. Multiple regulating branch pipes 22, evenly distributed at the bottom of the main inlet pipe 21, precisely deliver the coolant to various parts of the mold. The main outlet pipe 23 at the bottom of the regulating branch pipe 22 returns the cooled coolant, after heat absorption, to the water-cooled unit 3 via a second connecting pipe 5, forming a circulation. The control valve 24 at the top of the regulating branch pipe 22 can flexibly adjust the coolant flow rate based on the detection data from the temperature sensor 25. The temperature sensor 25, installed at the bottom of the regulating branch pipe 22, can monitor the temperature of the cooled coolant after heat absorption in real time. When the local temperature of the mold is too high, the temperature of the coolant in the corresponding regulating branch pipe 22 increases, the temperature sensor 25 feeds back data, and the control valve 24 reduces the coolant flow rate; conversely, it increases the coolant flow rate. This ensures that the cooling rate and temperature of the fixed mold assembly 11, the moving mold assembly 12, and the raw materials inside them remain uniform. Through the coordinated operation of each component, this structure effectively avoids the problems of inconsistent solidification speed and poor microstructure of aluminum alloy caused by uneven mold temperature. It reduces the probability of defects such as shrinkage cavities and deformation in die castings, improves the forming quality and dimensional accuracy of die castings, extends the service life of die casting molds, reduces production losses and costs caused by improper mold temperature control, and significantly improves the efficiency and benefits of aluminum alloy die casting production.

[0020] The device is used as follows: aluminum alloy material is die-cast using the die-casting mold mechanism 1. Coolant is supplied to the regulating branch pipe 22 via the water-cooling unit 3 through the first connecting pipe 4 and the main liquid inlet pipe 21. The coolant cools the die-casting mold mechanism 1 and the material inside it. The temperature of the coolant in the regulating branch pipe 22 after heat absorption is detected by the temperature sensor 25. When the temperature of the coolant in different regulating branch pipes 22 is not uniform, the flow rate of coolant in the regulating branch pipe 22 is controlled by the control valve 24, so that the cooling rate and temperature of the fixed mold assembly 11 and the raw material inside it are kept uniform.

[0021] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
