Abstract
The utility model relates to an improved structure of a diode plastic injection mold. The improved structure comprises a lower mold, a main plastic injection channel and a plurality of branch plastic injection channels are arranged on the lower mold, the branch plastic injection channels are respectively communicated with the main plastic injection channel, a check block is further arranged at one side of the lower mold, inserted in the main plastic injection mold and provided with an exhaust duct which is communicated with the main plastic injection channel. According to the improved structure, vent holes are prevented from being formed on the surface of a diode in plastic injection.
Description
Technical field
The utility model relates to the gel-injection mould of diode, particularly a kind of improvement structure of diode gel-injection mould.
Background technology
After the diode body is made, usually need to carry out at its outer surface the operation of injecting glue operation.The injecting glue operation is that diode is placed on the counterdie, and counterdie is provided with a main injecting glue road and a plurality of injecting glues shunting, and these injecting glue shuntings are communicated with main injecting glue road respectively, also is provided with a block in a side of counterdie, and main injecting glue road is carried out shutoff.During injecting glue, each diode is separately fixed in each injecting glue shunting, flow into epoxy resin in the main injecting glue glue road is attached to diode from each injecting glue shunting surface, can finish injecting glue.But because block seals at the matched moulds state, gas can't be discharged during injecting glue, and these gases have to flow near the injecting glue shunting the close block, thereby accumulate near in near the injecting glue shunting the block, thereby can cause product surface that pore is arranged, its quality and yield rate do not reach ideal effect.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of improvement structure of diode gel-injection mould, and the utility model can avoid diode surface when injecting glue to produce pore.
The technical scheme that realizes goal of the invention of the present utility model is as follows:
A kind of improvement structure of diode gel-injection mould, comprise counterdie, counterdie is provided with a main injecting glue road and a plurality of injecting glues shunting, these injecting glue shuntings are communicated with main injecting glue road respectively, side at counterdie also is provided with a block, block is inserted in the main injecting glue road, and described block is provided with the exhaust passage, and this exhaust passage is communicated with main injecting glue road.
The height of described exhaust passage is 0.01mm-0.03mm.
Adopted such scheme, owing to being provided with the exhaust passage that is communicated with main injecting glue road on the block, in to diode injecting glue process, the air that is arranged in main injecting glue road can be discharged by the exhaust passage, avoid these gases to discharge and accumulate near the injecting glue shunting that is positioned at the block, thereby after the utility model injecting glue is finished, do not have gas accumulation on the surface of diode, be not have pore on the diode to exist, improved the qualification rate of product.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1 is counterdie, and 2 is main injecting glue road, and 3 is the injecting glue shunting, and 4 is block, and 5 is the exhaust passage.
The specific embodiment
With reference to Fig. 1, the improvement structure of diode gel-injection mould of the present utility model, comprise counterdie 1, counterdie is provided with a main injecting glue road 2 and a plurality of injecting glues shunting 3, these injecting glue shuntings 3 are communicated with main injecting glue road 2 respectively, also are provided with a block 4 in a side of counterdie, and block is inserted in the main injecting glue road, described block is provided with exhaust passage 5, and this exhaust passage is communicated with main injecting glue road.The height of described exhaust passage is 0.01mm-0.03mm, and the height of exhaust passage is preferably 0.01mm.
Claims (2)
1. the improvement structure of a diode gel-injection mould, comprise counterdie, counterdie is provided with a main injecting glue road and a plurality of injecting glues shunting, these injecting glue shuntings are communicated with main injecting glue road respectively, side at counterdie also is provided with a block, block is inserted in the main injecting glue road, it is characterized in that: described block is provided with the exhaust passage, and this exhaust passage is communicated with main injecting glue road.
2. the improvement structure of diode gel-injection mould according to claim 1, it is characterized in that: the height of described exhaust passage is 0.01mm-0.03mm.
