Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted tree transportation technology, specifically a casting device for a quarter-sized end cap. Background Technology

[0002] Large end caps are crucial components in tank equipment or mechanical equipment such as pumps, typically serving a sealing and securing function. The design and manufacture of end caps must consider the precision of their fit with the tank or pump, as well as factors such as the operating pressure and temperature they must withstand. There are three main production methods for large end caps: **Single Round End Cap:** This type of end cap is manufactured in a single molding process and is suitable for smaller sizes. While production efficiency is high, it is limited by the size and capacity of the manufacturing equipment. **Two-Half End Cap:** This type of end cap consists of two semi-circular components joined together by welding or bolting. Suitable for medium-sized end caps, it facilitates transportation and installation while also meeting larger size requirements. **Quarter End Cap:** This type of end cap consists of four equally divided sector-shaped components, also joined by welding or bolting. Suitable for large end cap production, it effectively reduces transportation and installation difficulties and facilitates quality control during manufacturing.

[0003] However, in these production methods, especially for end caps produced using the quarter-production model, deformation is a common problem during the casting process. This deformation directly affects the quality of the finished end cap, making it unable to meet the predetermined process requirements, thus impacting the performance and reliability of the entire equipment.

[0025] In the above embodiment, when casting the quarter-end cap, the upper molding dummy box 7 is moved upward by the lifting device 5, so that the upper molding dummy box 7 is separated from the lower molding dummy box 6. The second electric actuator 13 drives the molding scraper 18 to move above the lower molding dummy box 6. The third electric actuator 15 drives the molding scraper 18 downward to move above the lower molding dummy box 6. The motor 17 drives the molding scraper 18 to rotate.
