Detailed Description
The utility model, as shown in fig. 1-3, comprises a mold frame body 1 and a plurality of rectifier bridge modules 2 fixedly arranged in the mold frame body;
a pouring liquid inlet 11 is formed in the middle of the die frame body;
the rectifier bridge module 2 comprises a plurality of rectifier bridge die cavity monomers 3 which are fixedly connected in sequence;
a pouring inlet 31 is formed in the top of the rectifier bridge die cavity single body 3; the pouring inlet 31 is communicated with the pouring liquid pouring inlet 11 through a flow channel; and an exhaust groove 32 is formed in the side surface of the rectifier bridge die cavity single body 3.
According to the scheme, through the structural improvement of the rectifier bridge die cavity single body 3, a lead surface exhaust groove 32 at the bottom of the rectifier bridge die cavity single body 3 (the bottom position of the rectifier bridge die cavity single body 3 in the figure 3) is eliminated, and exhaust is performed by slotting the side edge of the rectifier bridge die cavity single body 3; increase lead wire side wire casing angle simultaneously, do benefit to the carminative smooth and easy of moulding plastics, avoid the lead wire surface black to glue simultaneously and spill over. And as the lead is finally welded at a client, the welding performance cannot be influenced by residual glue.
A connecting part is arranged between the adjacent rectifier bridge die cavity single bodies 3; the middle part of the connecting part is provided with an air vent which is communicated up and down; the exhaust groove 32 communicates with an exhaust hole.
Four exhaust grooves 32 are arranged on the rectifier bridge die cavity single body 3 and are uniformly distributed on two sides of the rectifier bridge die cavity single body 3.
The exhaust grooves 32 are respectively symmetrically arranged on two sides of the rectifier bridge die cavity single body 3, and one side is provided with two exhaust grooves.
As shown in fig. 3, the air discharge grooves 32 are respectively formed in the upper and lower portions between the adjacent rectifier bridge mold cavity units 3 at the first position in the drawing (the arrow direction in fig. 3 is the air discharge direction), and after the injection molding liquid enters the inner cavity of the rectifier bridge mold cavity unit 3 from the pouring inlet 31, the air in the rectifier bridge mold cavity unit 3 is rapidly discharged through the air discharge grooves 32 which are symmetrically formed in the upper and lower portions, so that the pouring liquid fully flows into the inner cavity of the rectifier bridge mold cavity unit 3, and the air residue is reduced.
