Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of clamping devices of die casting inner pre-buried steel sleeve. BACKGROUND

[0002] High-pressure casting technology is a kind of casting process that uses the cavity of a mold to apply high pressure to molten metal. It has the characteristics of high precision, high efficiency and high strength. High-pressure casting, also known as pressure casting, is a method of filling a mold cavity with liquid or semi-liquid metal at high speed and forming and solidifying under high pressure to obtain a casting. This process is suitable for mass production of small and medium-sized castings, especially for manufacturing complex and precise parts.

[0003] In recent years, with the development of new energy vehicles, high-pressure casting technology is increasingly used in electric vehicle motor housings, battery trays and other applications. Integrated die casting technology is a typical example, which reduces the number of parts, improves production efficiency and reduces costs.

[0004] In the future, the development trend of high-pressure casting technology will be towards higher precision, higher efficiency and more environmentally friendly. Integrated die casting technology is an important trend in the future, which reduces the number of parts and simplifies the assembly process, improves production efficiency and reduces costs. In addition, the emergence of new die casting materials and the development of new die casting equipment will also promote the progress of high-pressure casting technology. With the global economic development and the increasing demand for precision parts in manufacturing, high-pressure casting technology will be applied in more fields, especially in new energy vehicles and intelligent manufacturing.

[0005] Aluminum alloy die casting inner pre-buried steel sleeve is placed into the mold before mold closing, and then positioned axially by mold closing. Axial positioning usually uses three cylindrical pins to press the steel sleeve. The current product structure is prone to leakage at the three positioning holes, so the three positioning holes are considered to be cancelled to prevent leakage. At the same time, the steel sleeve loses axial positioning, and the aluminum liquid will impact the steel sleeve and move during high-pressure casting, which ultimately leads to product structure and size requirements not being met. To meet this requirement, the radial fit between the steel sleeve and the mold is currently changed to interference fit, and the steel sleeve is placed manually and knocked with a wooden hammer to use friction to prevent the steel sleeve from moving.

[0006] The stability of the steel sleeve placed by hand during production is poor, and a certain proportion of the steel sleeve still has movement defects, which makes the production rhythm longer and the production efficiency lower, increasing the labor cost.

[0007] In view of the above defects, the designer actively researches and innovates to create a new type of die casting inner pre-buried steel sleeve clamping device, which has more industrial value. INVENTION CONTENTS
