Abstract
Disclosed in the utility model is a packaging die for a triode. The packaging die comprises an upper die body and a lower die body; top exhaust slots and bottom exhaust slots are arranged on separation ribs forming all mold cavities of the lower die body; and base pin exhaust slots corresponding to two base pin gaps one by one among three base pins of the triode are arranged on a press pin of the upper die body. According to the utility model, because the exhaust slots are additionally arranged on the die, air bubbles generated during the packaging can be effectively discharged.
Description
Technical field
The utility model relates to the triode encapsulating mould, relates in particular to the air discharge duct of triode die.
Background technology
The triode encapsulating mould comprises upper and lower mould, the lead frame of triode places the die cavity of upper and lower mould to carry out the injecting glue encapsulation, as illustrated in fig. 1 and 2, the separation rib in each coffin pit of formation of bed die is provided with air discharge duct 11 in the position of closing on the top, but when lead frame of triode is placed die cavity, lead frame meeting shield portions air discharge duct, cause the area of air discharge duct not enough, the gas that produces in the encapsulation can't effectively be discharged, cause the plastic shell of the product after the encapsulation to have bubble, do not reach the requirement of product quality.In addition, as shown in Figure 3, pressure pipe pin 3 positions of mold do not have air discharge duct, are unfavorable for the discharge of bubble yet.
The utility model content
The purpose of this utility model is in order to address the aforementioned drawbacks, a kind of effective triode encapsulating mould of discharging of the bubble that produces in the encapsulation process that makes to be provided.
The technical solution adopted in the utility model is: a kind of triode encapsulating mould, comprise upper and lower mould, and be provided with top air discharge duct and bottom air discharge duct on the separation rib in each coffin pit of formation of described bed die; Be provided with on the pressure pipe pin of mold and three pins of triode between two pin gaps pin air discharge duct one to one.
The beneficial effects of the utility model are: triode encapsulating mould of the present utility model has been set up air discharge duct, therefore, the bubble that produces in the encapsulation effectively can be discharged, in addition, in the situation of the width widen that makes former lower top air discharge duct, even also will have enough leaving areas after lead frame blocks, this will further strengthen exhaust effect.
