Mold capable of improving quality of main fin of cooling fin

Abstract

The invention discloses a mold capable of improving quality of a main fin of a cooling fin. The mold comprises a mold plate, wherein the top face of the mold plate is inwards concave to form a groove which penetrates through the mold plate, the lower portion of the mold plate is provided with a base plate, a plurality of elastic pieces are arranged in the groove, the bottom ends of the elastic pieces are fixed on the base plate, the top face of the mold plate is provided with a plurality of positioning blocks which are arranged outside the groove, and the positioning blocks are symmetrically distributed on the mold plate along the center of the mold plate. According to the mold, the positioning blocks are used for fixing workpieces so that displacement of the workpieces can be prevented, precision of workpiece forming is guaranteed, after flanging and forming of the workpieces, the workpieces are automatically pushed out, deformation of the workpieces cannot be caused, the flatness of the workpieces is thereby guaranteed, the flatness of the bottom of the manufactured main fin is stable, and accordingly the quality of a radiator behind the main fin is stable.

Description

technical field [0001] The invention relates to a mold, in particular to a mold capable of improving the quality of a heat sink main piece, which belongs to the field of automobile radiator forming. Background technique [0002] The radiator belongs to the automobile cooling system. The radiator in the engine water cooling system is composed of three parts: the water inlet chamber, the water outlet chamber, the main plate and the radiator core. The coolant flows inside the radiator core, and the air passes outside the radiator core. The hot coolant cools due to heat dissipation to the air, and the cold air heats up because it absorbs the heat emitted by the coolant, so the radiator is a heat exchange system. device. The car radiator is one of the key components of the engine cooling system. The main piece in the radiator is the key connecting part. The quality of the main piece directly affects the quality of the radiator. Nowadays, in the flanging forming process when man...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the easy displacement of the workpiece placed on the forming core block when the main sheet in the existing radiator is formed. After the positioning core block is flanged and formed each time, the staff needs to use utensils to pry the workpiece from the positioning core block. , which easily leads to the problem of workpiece deformation. A mold that can improve the quality of the main heat sink is designed. The mold uses positioning blocks to fix the workpiece to prevent the displacement of the workpiece and ensure the accuracy of the workpiece. Through the design of the elastic structure, it makes After the workpiece flanging is formed, the workpiece is automatically ejected without causing deformation of the workpiece, thereby ensuring the flatness of the workpiece, and the flatness of the bottom surface of the manufactured main piece is stable, thereby ensuring the stable quality of the radiator behind the main piece
