Description

Technical Field

[0001] The utility model belongs to the technical field of evaporator angle frame production and relates to an injection mold, in particular to an evaporator angle frame injection mold. Background Art

[0002] The evaporator angle bracket is a component used in air conditioning systems. It consists of a bracket body, a mounting slot, and a snap-on mechanism. The mounting slot, located on the bracket body, accommodates the evaporator's heat exchange tubes. The snap-on mechanism, located on the sidewalls of the mounting slot, secures the tubes in place. This structure ensures the secure attachment of the evaporator angle bracket and the tubes, preventing them from falling off the bracket. The evaporator angle bracket is designed to improve the efficiency and reliability of air conditioning systems. Through its specialized structure and functionality, it ensures the effective securing and use of the heat exchange tubes, thereby optimizing overall system performance.

[0003] A search revealed a Chinese patent document that discloses an injection mold capable of quickly demolding an object [Application Number: 202120999379.7; Publication Number: CN 215472851 U]. This injection mold capable of quickly demolding an object comprises a workbench, a first mold, and a second mold. An evaporator is bolted to the interior of the workbench. Fans are mounted on mounting brackets at both ends of the bottom of the evaporator. An air pump is mounted on one end of the workbench via a mounting bracket. The air outlet of the air pump is connected to a multi-way valve via a threaded groove. A first side panel is bolted to one end of the workbench. A cylinder is mounted on one side of the first side panel via a mounting bracket. An output shaft on one side of the cylinder is bolted to the first mold. This utility model uses a fan to blow cold air from the evaporator to cool the mold, accelerating the molding of the material inside and preventing cracking of the finished product due to large temperature differences. Furthermore, a push block pushes the finished product, enabling rapid demolding.

[0004] The fan disclosed in this patent blows out the cold air produced by the evaporator to cool the mold, which can accelerate the molding of the internal material and avoid cracking of the finished product due to large temperature differences. At the same time, the finished product can be pushed by the push block to achieve rapid demoulding. However, if the mold is not used for a long time, it is easy to be covered with dust and needs to be lubricated and protected to prevent internal rust and adhesion. Utility Model Content
