Abstract
The utility model discloses a connector cold welding die for large transfusion soft bags, which comprises an upper cold welding plate and a lower cold welding plate. Two opposite welding end faces are respectively arranged on the upper cold welding plate and the lower cold welding plate, a cut groove is arranged at least on one of the cold welding plates, and an elastic part is formed between the cut groove and the welding end face of the corresponding cold welding plate. The connector cold welding die for the large transfusion soft bags is simple in structure, low in cost and high in adaptability.
Description
Technical field
The utility model relates to food, field of pharmaceutical machinery, relates in particular to a kind of big infusion soft bag interface cold-welding mold.
Background technology
Current, connect in the mould at large-volume infusion soft bag interface cold welding, by the following cold welding fishplate bar seam interface in last cold welding fishplate bar in the patrix and the counterdie, and interface is pressed on the film bag.Yet the above-mentioned cold welding fishplate bar of going up generally adopts metal material to make with following cold welding fishplate bar, and the elastic deformation amount is little, and adaptivity is poor, if the interface size has deviation slightly, occurs rosin joint possibly or crosses weldering, and the quality that influence is welded has reduced the joint weld qualification rate.
The utility model content
The technical problems to be solved in the utility model is: the technical problem at prior art exists provides a kind of big infusion soft bag interface cold-welding mold simple in structure, with low cost, that adaptivity is strong.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of big infusion soft bag interface cold-welding mold, comprise cold welding fishplate bar and following cold welding fishplate bar, the described cold welding fishplate bar of going up is equipped with a welding end surface with following cold welding fishplate bar, two welding end surface are oppositely arranged, offer grooving on described one of go up in cold welding fishplate bar and the following cold welding fishplate bar at least, be formed with elastic portion between the welding end surface of described grooving and corresponding welded plate.
As further improvement of the utility model:
Described grooving is the through slot with the welding end surface profiling of corresponding welded plate.
Distance between the welding end surface of described grooving and corresponding welded plate is 2 to 3 millimeters.
On the plane vertical with the matched moulds direction, the projection of welding region is positioned at the projection inside of described grooving in the described welding end surface.
Compared with prior art, advantage of the present utility model is: the utility model big infusion soft bag connects mould with the interface cold welding, simple and compact for structure, with low cost, by in last cold welding fishplate bar and following cold welding fishplate bar, offering grooving on one of at least, make between welding end surface and the grooving and form elastic portion, when matched moulds welds, can absorb the dimensional discrepancy of interface, adaptivity is strong, has guaranteed welding quality, has improved solder yield.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 be among Fig. 1 A-A to cutaway view.
Marginal data:
1, goes up the cold welding fishplate bar; 2, following cold welding fishplate bar; 3, grooving; 4, welding end surface; 5, elastic portion.
The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model big infusion soft bag interface cold-welding mold, comprise cold welding fishplate bar 1 and following cold welding fishplate bar 2, last cold welding fishplate bar 1 and following cold welding fishplate bar 2 are equipped with a welding end surface 4, two welding end surface 4 are oppositely arranged, all offer grooving 3 on last cold welding fishplate bar 1 and the following cold welding fishplate bar 2, be formed with elastic portion 5 between the welding end surface 4 of each grooving 3 and corresponding welded plate.When welding, elastic portion 5 can absorb the interface dimensional discrepancy, makes the cold-welding mold adaptivity strong, guarantees welding quality, improves solder yield.
In the present embodiment, grooving 3 is and the through slot of welding end surface 4 profilings of corresponding welded plate, makes the thickness of elastic portion 5 each several parts even, and elastic portion 5 stress deformation unanimities have further improved welding quality in the time of can guaranteeing to weld.Simultaneously, distance between the welding end surface 4 of each grooving 3 and corresponding welded plate is set to 2 to 3 millimeters, in the present embodiment, the distance between the welding end surface 4 of each grooving 3 and corresponding welded plate is set to 2.5 millimeters, and thin thickness makes elastic portion 5 have elastic deformability preferably.
In the present embodiment, on the plane vertical with the matched moulds direction, the projection of welding region is positioned at the projection inside of grooving 3 in the welding end surface 4.Last cold welding fishplate bar 1 that the matched moulds direction also promptly is oppositely arranged and following cold welding fishplate bar 2 are mutually near the direction of welding, in the present embodiment, the plane vertical with the matched moulds direction is plane shown in Figure 2, the view field of welding region in the C region representation welding end surface 4 among Fig. 2, the view field of B region representation grooving 3, the C zone is positioned at the inside in B zone, and the weld zone is positioned on the elastic portion 5 fully like this, can adapt to the deviation of soldered each spot size of thing in the time of can guaranteeing to weld.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should propose, for those skilled in the art, in the improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
