Abstract
The utility model provides a rib cutting and discharging structure which includes a discharging plate. The lower side of the discharging plate is provided with a discharging mold insert. The inside of the discharging mold insert is fixed with a positioning needle. The rib cutting and discharging structure is characterized in that the discharging mold insert is provided with a discharging nail fixing hole at a position which is close to the positioning needle. The inside of the discharging nail fixing hole is provided with a discharging nail. The discharging plate is provided with a through hole at a position which is above the discharging nail fixing hole. The inside of the through hole is provided with a plug screw, and a spring is arranged between the discharging nail and the plug screw. Through arranging the discharging nail at the position which is close to the positioning needle, a product can be pushed out of the positioning needle under the reaction force of the spring in die opening, so the product at a positioning place can not be blocked on the positioning needle, and consequently the discharging becomes smooth, and the product quality is also improved.
Description
Technical field
The utility model relates to a kind of muscle discharging structure of cutting, and is used for the location, useless framework excision back of semiconductor plastic package product (like 220 series of products) product is smooth and easy coming off, and belongs to technical field of mold.
Background technology
In cutting the muscle process, elder generation is by pilot pin implementation framework fine positioning before the mould matched moulds.As depicted in figs. 1 and 2; Be traditional muscle discharging matched moulds and die opening state figure of cutting, said traditional cut the muscle discharging structure by discharging block 1, pilot pin 2, unloading block 3, discharging mold insert 4, stripper 5, die socket 6, the cutter 7 of cutting edge down, cut under the muscle cutter 8 and following cutter block 10 and form.Described die socket 6 upsides are provided with cutter 7 under the side cut, cut cutter 8 and following cutter block 10 under the muscle; Plastic packaging product 9 be located at cut edge down cutter 7 with cut under the muscle on the cutter 8, the downside of stripper 5 is provided with discharging block 1, unloading block 4 and discharging mold insert 3, discharging mold insert 3 internal fixation have pilot pin 2; The product encapsulation all is a mould preparation later; Take out the mould preparation product by stock shelf,, cut the muscle cross cutting then and remove frame waste again by remove running channel and cast gate towards mold.Owing to adorn feeding pipe after mould product need be cut muscle; So can not be installed in counterdie to the mold position pin; When requiring to locate and going into pipe, select pilot pin to be installed in patrix, promptly can not influence product orientation again can smooth and easy tubulature; It is not smooth that patrix location shortcoming is to produce discharging sometimes between the pilot pin and place, location product. and pilot pin can produce the influence of pulling to the place, a product aperture of location, and such quality to product has certain influence.At this moment just need a kind ofly can in accurate positioning, reach discharging structure smoothly, to reach the purpose that discharging is smooth and easy, improve the quality of products.
Summary of the invention
The purpose of the utility model provides a kind of discharging and cuts the muscle discharging structure smoothly.
In order to achieve the above object, the utility model provides a kind of muscle discharging structure of cutting, and comprises stripper; The downside of stripper is provided with the discharging mold insert, and discharging mold insert internal fixation has pilot pin, it is characterized in that; Described discharging mold insert is positioned at the other position of pilot pin and is provided with discharging nail fixing hole, is provided with the discharging nail in the discharging nail fixing hole, and the position that stripper is positioned at discharging nail fixing hole top is provided with through hole; Be provided with plug screw in the through hole, be provided with spring between discharging nail and the plug screw.
Preferably, the beeline between described discharging nail fixing hole inwall and the pilot pin outer wall is 6.0mm～7.0mm.
Preferably, the distance between described discharging screw top portion's outer wall and the discharging nail fixing hole inwall is 0.03mm.
Preferably, the described muscle discharging structure of cutting also comprises die socket, and the upside of die socket is provided with the cutter of cutting edge down, cuts cutter and following cutter block under the muscle, and the plastic packaging product is located at the cutter and cutting under the muscle on the cutter of cutting edge down.
Preferably, the downside of described stripper also is provided with discharging block and unloading block.
The utility model increases a discharging nail at the other relative position of pilot pin; The discharging nail ejects pilot pin to product under the situation of spring reaction power when the mould die sinking; Place, location product can be stuck on the pilot pin, thereby it is smooth and easy to reach discharging, the purpose of improving the quality of products simultaneously.

Fig. 2 is traditional muscle discharging structure die opening state figure that cuts;
Fig. 3 cuts the state diagram of muscle discharging structure matched moulds for the utility model;
Fig. 4 cuts muscle discharging structure die opening state figure for the utility model.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
Like Fig. 3 and shown in Figure 4; For the utility model cut muscle discharging structure matched moulds and die opening state figure, described cut the muscle discharging structure by discharging block 1, pilot pin 2, unloading block 3, discharging mold insert 4, stripper 5, die socket 6, the cutter 7 of cutting edge down, cut cutter 8 under the muscle, cutter block 10 and discharging nail 11 are formed down.The downside of stripper 5 is provided with discharging mold insert 3; Discharging mold insert 3 internal fixation have pilot pin 2, it is characterized in that, described discharging mold insert 3 is positioned at pilot pin 2 other positions and is provided with discharging nail fixing hole; Be provided with discharging nail 11 in the discharging nail fixing hole; The position that stripper 5 is positioned at discharging nail fixing hole top is provided with through hole, is provided with plug screw in the through hole, is provided with spring between discharging nail 11 and the plug screw.Beeline between described discharging nail fixing hole inwall and pilot pin 2 outer walls is 6.5mm.The distance that described discharging is followed closely between 11 top exterior walls and the discharging nail fixing hole inwall is 0.03mm.The described muscle discharging structure of cutting also comprises die socket 6, and the upside of die socket 6 is provided with the cutter 7 of cutting edge down, cuts cutter 8 and following cutter block 10 under the muscle, and plastic packaging product 9 is located at the cutter 7 and cutting under the muscle on the cutter 8 of cutting edge down.The downside of described stripper 5 also is provided with discharging block 1 and unloading block 4.
During use, pilot pin 2 plays positioning action when pilot pin 2 imports the framework of plastic packaging product 9, reaches through the mould matched moulds and precisely cuts the muscle purpose.Pilot pin 2 is up moved with patrix when the mould die sinking; Pilot pin 2 product of locating might drive product and up move; Pilot pin 2 is monolateral 0.02mm with location hole gap value, and plastic packaging product 9 can up move with pilot pin 2 under some uncertain factors. get stuck with regard to formation like this and discharging not smooth.Thereby influence the useful life of mould and the quality of product.The utility model mould is in matched moulds; Discharging nail 11 has been pressed in above the plastic packaging product 9; Discharging nail 11 ejects pilot pin 2 at following plastic packaging product 9 of the situation of spring reaction power when the mould die sinking, thereby plastic packaging product 9 can not move with pilot pin 2. to reach discharging purpose smoothly.This structure adds a discharging nail 11 on pilot pin 2 next doors, cost is not high, and discharging is smooth and easy, has strengthened the quality of product greatly.
