Embodiment 1

[0039] Such as figure 1 As shown, the present invention provides a rectifying square bridge manufacturing mold, which includes two first mold 1 and second mold 2 that are installed in cooperation with each other.

[0040] Such as Figure 2 to Figure 5 As shown, the top surface of the first mold 1 is evenly distributed with a frame mechanism 11, and the frame mechanism 11 includes a square positioning rod 12 and a first pin hole 13, a second pin hole 14, and a symmetrical distribution centered on the square positioning rod 12. The third pin hole 15 and the fourth pin hole 16, the first lead frame 131 is clamped in the first pin hole 13, the second lead frame 141 is clamped in the second pin hole 14, and the third lead frame 141 is clamped in the second pin hole 14. A third lead frame 151 is clamped in the pin hole 15, and a fourth lead frame 161 is clamped in the fourth pin hole 16;

[0041] There is a connecting hole 121 matched with the connecting shaft 22 inside the square...

Embodiment 2

[0053] The invention provides a manufacturing method using the manufacturing mold to manufacture a rectifying square bridge, the manufacturing method comprising the following steps:

[0054] Step 1: Insert the pin piece 1312 into the q-shaped hole 1311, the b-shaped hole 1511 and the inverted b-shaped hole 1611 respectively;

[0055] Step 2: Place the second mold 2 on the glue dispenser, and use the glue dispenser to dispense glue on the first glue dispensing station 241 and the second glue dispensing station 2311;

[0056] Step 3: Remove the second mold 2 from the dispenser, match the second mold 2 with the first mold 1, insert the connecting shaft 22 into the connecting hole 121, and screw the positioning column 18 into the second positioning hole 27 to obtain a complete mold ;

[0057] Step 4: Put the complete mold into the welding furnace, keep the welding temperature at 320°C, and the welding time for 3 minutes, so that the lead pieces 1312 are respectively welded to the...

Abstract

The invention discloses a mold for manufacturing a rectifying square bridge. The mold comprises two first molds and second molds which are installed in cooperation with each other. The present invention sets two identical welding pieces through the setting of the first L-shaped mounting piece and the third L-shaped mounting piece. While saving resources, it effectively solves the problem of easy occurrence of mold clamping and glue dispensing during the production of rectifying square bridges. Dislocation of welding points and inconvenient welding; through the setting of the connecting shaft and connecting hole, the first positioning hole, the second positioning hole and the positioning column, the accuracy of the positioning of the upper frame and the welding frame during the mold clamping process is ensured; the present invention The designed rectifying square bridge manufactured by the manufacturing mold saves resources, has precise positioning, and can effectively improve the rate of good products.

Description

technical field [0001] The invention belongs to the field of rectifier bridges, and in particular relates to a rectifier square bridge manufacturing mold and a manufacturing method thereof. Background technique [0002] The rectifier bridge is to seal the rectifier tube in a shell. Its main function is to rectify and adjust the direction of the current. It is usually connected by two or four rectifier silicon chips. Two are called half bridges, and four are called bridges. It is a full bridge, and the exterior is encapsulated with insulating plastic. The high-power rectifier bridge is encapsulated with a zinc metal shell outside the insulation layer to enhance heat dissipation performance. There are many types of rectifier bridges, including flat, round, and square bench shapes and patch), etc., in the preparation of the rectifier square bridge, it is mainly to place a suitable welding frame on the upper frame, put the lead sheet in the welding frame, and place the welding s...
