Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a drying device for titanium alloy investment casting mold shells. Background Technology

[0002] Shell drying refers to the process of creating a model of the part using wax or other fusible materials to obtain a high-precision casting shape. Multiple layers of ceramic slurry are then coated onto the wax model to form a hard shell. The wax model is then removed through drying and firing, leaving a cavity within the shell that matches the dimensions of the part. Molten metal is poured into this cavity, and after it cools and solidifies, the shell is broken to obtain a casting that perfectly matches the shape and structure of the wax model. Shell drying is a crucial step in the investment casting process.

[0003] Current mold shell drying processes lack effective drying control methods, leading to uneven or insufficient drying. This can cause cracking and deformation during subsequent dewaxing, firing, or pouring processes, severely affecting the dimensional accuracy and surface quality of the castings. Furthermore, improper control of ambient humidity or temperature during drying can result in residual moisture or impurities inside the mold shell, causing defects such as porosity and inclusions during pouring, reducing the mechanical properties and service life of the castings. In addition, excessively long drying times or unstable processes can prolong the production cycle, reduce production efficiency, and increase production costs. Therefore, optimizing the mold shell drying process and improving drying uniformity and efficiency are crucial for improving the quality and production efficiency of investment casting. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for titanium alloy investment casting mold shells to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a titanium alloy investment casting mold shell drying device, comprising a mold shell drying platform, four casters at the bottom of the mold shell drying platform, a support structure at the top of the casters, two rows of four ducted fan brackets in the middle of the support structure, ducted fan brackets equipped with ducted fans, and a mold shell placement platform at the top of the support structure.

[0006] Preferably, the top of the caster wheel is provided with a support frame to ensure the mobility of the titanium alloy investment casting mold shell drying device.

[0007] Preferably, the ducted fan accelerates airflow.

[0008] Preferably, the mold shell placement platform is composed of several steel bars with a certain interval to ensure that the mold shell can be subjected to the action of the ducted fan.

[0009] Preferably, the anti-fall guardrail ensures that the mold shell placed on the mold shell placement platform will not fall.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Ducted fans, by generating high-speed, uniform airflow, effectively accelerate the evaporation of moisture from the mold shell surface, shortening the drying time of each coating layer. Simultaneously, uniform airflow prevents shell cracking or deformation caused by excessively rapid localized drying, thereby improving the overall quality and strength of the mold shell. This method not only significantly improves drying efficiency and shortens the production cycle but also reduces casting defects caused by insufficient drying, ultimately increasing the success rate and quality of investment casting.

[0012] 2. Ducted fans not only accelerate the drying process of the mold shells but also work in conjunction with the environmental control system to help maintain a constant temperature in the drying area. Through uniform airflow, ducted fans can disperse heat, reduce localized temperature fluctuations, and thus lower the operating load on the air conditioning system. This not only significantly reduces energy consumption but also extends equipment lifespan and lowers maintenance costs. For businesses, this highly efficient and energy-saving drying method not only improves production efficiency but also effectively controls energy consumption and production costs, achieving a dual optimization of economic and environmental benefits and providing strong support for sustainable production.

[0013] 3. Bottom ventilation effectively optimizes the mold drying process. By installing a ventilation system at the bottom of the drying area, airflow can evenly pass through the mold surface from bottom to top, ensuring simultaneous drying of all parts of the mold and avoiding the problem of needing to flip it over due to uneven drying on one side, as in traditional drying methods. This method not only reduces manual operation steps but also significantly reduces the risk of mold damage caused by flipping operations, thereby improving the overall quality and yield of the mold.
