A static disc precision forming die structure for new energy vehicle air-conditioning compressors

Abstract

The invention discloses an accurate forming die structure for a stator disc of an air conditioner compressor of a new energy automobile. The die structure comprises a convex die, a concave die and a backpressure structure, wherein the backpressure structure comprises a spiral backpressure body, an outer ring backpressure body, ejection rods, an ejection rod supporting plate, a spring and a cushion plate; the outer ring backpressure body is located at the periphery of the spiral backpressure body; the spiral backpressure body corresponds to a spiral bulge of the stator disc; the outer ring backpressure body corresponds to an outer ring bulge of the stator disc; the ejection rods are arranged at the lower ends of the spiral backpressure body and the outer ring backpressure body; the ejection rod supporting plate is arranged at the lower ends of the ejection rods; the cushion plate is located below the ejection rod supporting plate; the spring is arranged between the ejection rod supporting plate and the cushion plate; and the ejection rod supporting plate in the backpressure mechanism is located below the concave die. Compared with the prior art, the die structure disclosed by the invention has the following advantages: accurate forming for the stator disc can be realized, destroy for a metal fibre flow line due to the subsequent machining is avoided, the utilization rate of materials and the mechanical property of the stator disc are increased, and the cost is reduced.

Description

technical field [0001] The invention relates to a molding die for new energy automobile parts, in particular to a static disk precision forming mold structure for an air conditioner compressor of a new energy automobile. Background technique [0002] The static disk is a key part of the air conditioner of new energy vehicles. As the world's largest new energy vehicle market, according to the "13th Five-Year Plan", the new energy vehicle market will further expand in the future, and the demand for static disks will also continue to increase. At the same time, the static disk, as a key part of the automobile air-conditioning compressor, needs to meet the long-term and stable work, so the requirements for the performance of the static disk are getting higher and higher. Since there are many types of scroll disks, there are many types of static disks, and the structure is complex. For general static disk structures, please refer to figure 1 , the height of the outer ring protru...

Problems solved by technology

Combined with practical experience, method 1 not only has a low material utilization rate, but also cuts off the fiber streamline of the metal structure during processing, which reduces performance; method 2 is prone to internal defects such as pores; method 3 has inconsistent metal flow rates during conventional extrusion, which is difficult Ensure that the height of the protrusions 22 of the outer ring is consistent, and the height of the end face of the spiral protrusions 24 cannot be guaranteed, and a large amount of machining is still required in the follow-up, which reduces the utilization rate of materials
