Abstract
The utility model discloses an S-shaped runner plastic package body of four groups of metal gauze packing (MGP) moulds. The S-shaped runner plastic package body of four groups of MGP moulds comprises a charging barrel (1) which is used for feeding, two sides of the charging barrel (1) are respectively connected with 2-5 rows of cavities through a strange-shaped runner, and glue inlets (8) are arranged in the joints of the cavities and strange-shaped runners. Strange-shaped runner sprues (2) are arranged in the strange-shaped runner between a first row of cavities and a second row of cavities, so fed materials are enabled to flow into the glue inlets (8) of the first row of cavities. The S-shaped runner plastic package body of the four groups of MGP moulds has the advantages that the S-shaped strange-shaped runner sprues are adopted to fill a plurality of products continuously, so the filling efficiency can be improved, and the production cost is lowered.
Description
Technical field
The utility model relates to the special-shaped flow passage plastic-sealed body, relates in particular to the S type runner plastic-sealed body for four groups of MGP moulds.
Background technology
Present increasingly development along with the semiconductor packages industry, compete also more and more fierce, the profit of product is then but in constantly compression minimizing, at present behind IC semiconductor in the road packaging process, because the structural design of lead frame is to the development of many rows multiple row, and the width widen of lead frame also has limitation, so just requiring band at original width to enable to encapsulate mostly is products, the single spacing of product is less, and is closeer.As shown in Figure 1, particularly outstanding especially as the product packaging efficiency problem of this quasi-tradition of DIP8L, once can only encapsulate two products, to die cavity 10 filling chargings, flow into next die cavity by line flowing channel 11 by cast gate 9 again.This just requires to encapsulate the cost of enterprise's reduce product.And traditional double DIP8L can't satisfying the market rival demand.
The utility model content
Problem to be solved in the utility model is that existing single or double DIP8L encapsulating products is limited, can not need by satisfying the market, provides the single spacing of a kind of product less, closeer many row DIP8L S shape special-shaped flow passage plastic-sealed bodies for this reason.
The technical solution of the utility model is: a kind of S type runner plastic-sealed body for four groups of MGP moulds, it comprises the barrel for charging, the barrel both sides are connected with 2-5 row die cavity by shaped flow channel respectively, described die cavity and shaped flow channel junction have glue-feeder, described shaped flow channel has the shaped flow channel cast gate between first row and second row die cavity, make charging flow into the glue-feeder of first row die cavity.
Die cavity in the such scheme has respectively five rows in the barrel both sides.
The improvement of this programme is that described shaped flow channel is the S type.
The beneficial effects of the utility model are by adopting a plurality of products of the S shape continuous filling of special-shaped flow passage cast gate, pack effectiveness is improved, having reduced production cost.
Description of drawings
Fig. 1 is existing single DIP8L schematic diagram;
Fig. 2 is the utility model schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 2, the utility model comprises the barrel 1 for charging, barrel 1 both sides are connected with 2-5 row die cavity by shaped flow channel respectively, described die cavity and shaped flow channel junction have glue-feeder 8, described shaped flow channel has S shape runner cast gate 2 between first row and second row die cavity, make charging flow into the glue-feeder 8 of first row die cavity.
Traditional two products of DIP8L straight line filling, position, a sprue cisoid chamber of the utility model intersect to form S shape and cross each product of continuous filling by glue-feeder 8 again.
Preference of the present utility model is that described die cavity has respectively five rows in barrel 1 both sides.The product that can encapsulate continuously like this is more, and the utility model is not limited to only have five row's die cavities certainly, can arrange as required more.
The utility model can also be designed to the S type to shaped flow channel, need like this filling material can shaped flow channel flow more smooth, flow into more efficiently the glue-feeder of every row's die cavity.
The utility model is like this work: filler such as resin are filled into the first row die cavity 3 of first row die cavity plastic-sealed body by cast gate, then enter the second row die cavity 4 of second row plastic-sealed body at the glue-feeder 8 of every row's die cavity by S shape runner, enter successively again the 3rd the 5th row's die cavity 7 of arranging die cavity 5, the 4th row's die cavity 6 and last row and be filled to the die cavity plastic-sealed body, realize five row's intersection S shape special-shaped flow passage cast gate filling encapsulation.
Claims (2)
1. S type runner plastic-sealed body that is used for four groups of MGP moulds, it is characterized in that it comprises barrel (1) for charging, barrel (1) both sides are connected with 2-5 row die cavity by S shape runner respectively, described die cavity and S shape runner junction have glue-feeder (8), described S shape runner has S shape runner cast gate (2) between first row and second row die cavity, make charging flow into the glue-feeder (8) of first row die cavity.
2. a kind of S type runner plastic-sealed body for four groups of MGP moulds as claimed in claim 1 is characterized in that described die cavity has respectively five rows in barrel (1) both sides.
