Abstract
An improved mould forming insert convenient for glue removal comprises an insert body and an insert matching body. The lateral surface of the insert matching body is closely matched with the lateral surface of a base pin, and a glue containing area is arranged between the top surface of the insert matching body and the bottom surface of the base pin. The improved mould forming insert has the advantages that by the aid of the structure, the lateral surface of the insert matching body is closely matched with the lateral surface of the base pin, so that residual waste glue on the lateral surface of the base pin after glue sealing is smaller in amount, the glue containing area is arranged between the top surface of the insert matching body and the bottom surface of the base pin, so that final residual waste glue on the bottom surface of the base pin entering from a matching seam when the insert is formed is larger in amount, waste glue on the bottom surface of the base pin is cut off simultaneously while the base pin is cut off and separated during follow-up glue removal, and the waste glue on the lateral surface of the base pin is extremely small in amount and accordingly can be removed quite easily together with the waste glue on the bottom surface of the base pin.
Description
Technical field
The utility model relates to a kind of mould molding mold insert, is a kind of modified form mould molding mold insert of being convenient to remove glue specifically.
Background technology
In the assembling production process of semiconductor components and devices, remove glue when again the pin that connects together being cut off after need carrying out sealing and handle pin usually, at last pin is carried out tin plating technique.When utilizing existing mould molding mold insert that pin is carried out the sealing operation, owing to inevitably have the gap between mould molding mold insert and pin, thereby cause all having unnecessary scrap rubber in the bottom surface and the side of pin, in removing the glue process, separate except the pin that connects together being cut off, can also excise in the lump along the scrap rubber of band, but can't remove the scrap rubber of pin side the pin bottom surface.Owing to the existence of pin side scrap rubber, in the time of will being unfavorable for follow-up the plating tin is plated in the side of pin, and then the quality of product is caused harmful effect.
Summary of the invention
At the weak point of existing mold moulding mold insert, the purpose of this utility model provides a kind of modified form mould molding mold insert of being convenient to remove glue, utilize it that pin is carried out sealing after, be convenient to follow-up glue and the operation such as zinc-plated removed.
For achieving the above object, technical solution adopted in the utility model is: a kind of modified form mould molding mold insert of being convenient to remove glue, comprise mold insert main body and mold insert ligand, and the side of mold insert ligand and the side of pin closely cooperate; Be provided with between the end face of mold insert ligand and the bottom surface of pin and hold Jiao Qu.
The beneficial effects of the utility model are: owing to adopt said structure, the side of mold insert ligand and the side of pin closely cooperate, make residue in the pin side after the sealing the scrap rubber amount seldom; Be provided with between the end face of mold insert ligand and the bottom surface of pin and hold Jiao Qu, more in the scrap rubber amount of pin bottom surface when making moulding by cooperating the slit to enter final residue; Remove in the glue process follow-up, cut off the scrap rubber that cuts off the pin bottom surface when separating pin,, therefore be easy to be eliminated together by the scrap rubber amount of pin bottom surface is related because the scrap rubber amount of pin side is few.The utility model modern design, rational in infrastructure, the pin after the sealing extremely is convenient to follow-up remove glue work, and then tin is plated in when being very beneficial for follow-up the plating side of pin, guarantees to have excellent generalization values thereby provide a to the quality of product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is respectively among the figure: (1) mold insert main body, and (2) mold insert ligand, (3) hold Jiao Qu, (4) pin, (5) scrap rubber.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, a kind of modified form mould molding mold insert of being convenient to remove glue of the utility model comprises mold insert main body 1 and mold insert ligand 2, and the side of the side of mold insert ligand 2 and pin 4 closely cooperates; Be provided with between the bottom surface of the end face of mold insert ligand 2 and pin 4 and hold glue district 3.
The above, it only is a kind of preferred embodiment of the utility model, be not that technical scope of the present utility model is imposed any restrictions, every foundation technical spirit of the present utility model all still belongs in the scope of the utility model technology any trickle modification, equivalent variations and modification that top embodiment did.
