Description

Special split type of USB Housing holds fever board Technical Field The application relates to the technical field of powder metallurgy, in particular to a split type setter plate special for USB (universal serial bus) Housing. Background With the development of technology, the consumer electronics industry has also entered an important period of rapid revolution and innovation, and the sales of smart phones, tablet computers, wearable devices, and other digital products have increased significantly in recent years. The USB Type C interface integrating high-power supply capability, high-speed data transmission, compatibility with various protocols and support of forward and reverse plug design becomes a main stream form of a consumer electronic product interface. USB Housing is a Housing for USB Type C interfaces, typically used to protect internal terminals, PCB boards, and cables, and to provide mechanical support, electromagnetic shielding, and plug durability. Meanwhile, consumer electronic products are developing towards a light and thin direction, and various USB Housing are also designed to be more and more miniaturized. The USB Housing is small in size, complex in structure, high in surface profile and limited in productivity due to the fact that the traditional CNC machining is adopted. The metal powder injection molding technology (MIM) has significant advantages in manufacturing USB Housing, and is particularly suitable for high-precision, complex-structure, mass-production scenarios. For metal powder injection molding techniques, the design of ceramic setter plates is very important. Firstly, during the sintering process of metal powder injection molding, the green body is contracted to a certain extent, and when the thin edges of the product contact the ceramic setter plates, the friction force generated during the contraction process can cause deformation of the thin edges. Meanwhile, in the shrinkage process, if the placing mode of the green body on the ceramic plate is unreasonable, the suspended part can be deformed under the action of gravity. In addition, internal stresses of the green body due to injection molding can lead to deformation of the product during sintering. Therefore, how to reduce the three deformation effects in the sintering process is an urgent problem to be solved when designing the setter plates. Disclosure of Invention In order to solve the existing technical problems, the embodiment of the application provides a split type setter plate special for USB Housing. The technical scheme is as follows: In a first aspect, a special split-type setter plate for USB (universal serial bus) Housing is provided, comprising a base and a bolt piece matched with the base; The four corners of the base are respectively provided with a support column, a first boss is arranged in the middle of the base, a groove is arranged in the center of the first boss, the first boss can be matched with the cavity of the USB Housing, a C-shaped groove is arranged on the base around the first boss, and a through groove is arranged on the opposite side of the C-shaped groove; The latch component is of a T-shaped double-layer boss structure, an upper-layer boss is matched with the groove of the first boss, and a lower-layer boss is matched with the USB holding fish mouth part.
