Description

Metal powder injection moulding slide caliper rule body plastic frock

The technical field is as follows:

the utility model belongs to the technical field of the frock of part shaping usefulness and specifically relates to just a metal powder injection moulding slide caliper rule body plastic frock.

The background art comprises the following steps:

calipers are measuring tools, and the main types are vernier calipers, calipers with meters and digital display calipers. The main parts of the calipers are a caliper body and a caliper frame. The ruler body and the ruler frame are complex in shape and appearance, and the size requirement is high. Therefore, the processing efficiency is low and the cost is high. Because the caliper has a large annual demand, a processing technology which can meet the quality requirement, has high processing efficiency and low cost is urgently needed.

The main raw materials of present slide caliper rule are carbon steel, can take place to rust the condition that influences slide caliper rule measurement accuracy in the use. Due to the characteristic that stainless steel is difficult to process, the caliper made of the stainless steel material has the characteristics that the caliper body and the caliper frame are large in appearance, so that the machining amount is large, the condition that the deformation size of parts does not meet the requirement easily occurs, and the precision and the service life of the caliper are affected.

As a near-net forming process, the metal injection forming process can meet the requirement of forming a product at one time to a greater extent, and the obtained product can meet the product requirement only by a small amount of machining, so that the raw materials and the production cost can be greatly saved, and the processing and manufacturing requirements of the caliper part, namely the caliper body and the caliper frame are very met. However, a product obtained by sintering in a metal injection molding process is deformed, the larger the size specification is, the larger the deformation of the product is, and the length direction of the caliper body is longer, so that the sintered caliper has larger deformation, and the deformed size cannot meet the requirement of subsequent slightly-machined lean production.
