AI Technical Summary
During the thermal degreasing process, existing degreasing fixtures are prone to deformation of the molded body due to heat conduction, which in turn affects the quality of the product and may cause cracks.
A degreasing fixture structure is designed, including a support frame assembly and a barrier assembly. The barrier assembly reduces the probability of thermal deformation by blocking partial conduction and convection, and allows a certain amount of fluid to flow and quickly dissipate heat through holes and long holes.
It effectively reduces the probability of thermal deformation during degreasing, improves product quality, and reduces the risk of cracks in subsequent sintering processes through rapid heat dissipation.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of degreasing clamps, in particular to a degreasing clamp structure. Background Art
[0002] The existing degreasing jigs can stack 5 products on each jig. They are designed to minimize structural deformation. The X-shape on the top is to prevent thermal deformation of the structure during the thermal decomposition and degreasing process. The advantage of this jig is that the fluid flows smoothly inside the structure, but during the heating process of the thermal decomposition and degreasing process, there is a problem of deformation of the molded body caused by heat conduction. The deformation of the molded body remains the same during the sintering process after degreasing, and it may cause cracks in the product. In order to minimize this thermal deformation, there is a method of controlling the heating rate, but it will correspondingly extend the process time and increase the cost of the product.

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] Attached Figure 1-4 The degreasing fixture structure described in the utility model comprises a rectangular support frame assembly for carrying a number of products that need to be degreased, and a rectangular barrier assembly that is sleeved on the outer wall of the frame assembly to completely cover the upper and lower material ports of the frame body; the barrier assembly can block part of the conduction and convection, and a certain amount of fluid can flow through the inside; the barrier assembly comprises a number of barrier plates attached to the outer wall of the support frame assembly and welded to each other, holes for a certain amount of fluid to flow are respectively arranged on the several barrier plates, and long strip holes for rapid cooling are arranged in the middle above the barrier plates on the outer walls on both sides of the upper and lower material ports of the support frame assembly; the support frame assembly comprises a support frame body, and a number of support rods arranged on both sides of the inner wall of the support frame body for supporting products; the several support rods on both sides of the inner wall of the support frame body are arranged in sequence from top to bottom.

During the degreasing process, due to the blocking of the barrier plates, part of the conduction and convection can be effectively controlled, and a certain amount of fluid can flow through the holes, thereby reducing the probability of thermal deformation during degreasing. When the degreasing is completed, the long holes can effectively and quickly dissipate heat.

Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
