The invention relates to the technical field of dies, in particular to an overlapped sliding block structure.

[ background of the invention ]

Some products require two adjacent barb structures on the side edge, as shown in fig. 1 and fig. 2, fig. 1 is a schematic diagram of the product, and fig. 2 is a side view of the product. Fig. 2 shows that the two barb structures 11 and 12 of the product 10 are close to each other and have different forming movement directions, so that the product cannot be formed by the same slider. The existing sliding block structure cannot be molded aiming at the double-barb structure.

The former molding method is to increase the thickness of the meat at a pre-processing barb part and then mill the barb structure through CNC processing. However, the thick part of the casting will generate thermal junctions during condensation, which results in the occurrence of defects such as shrinkage cavity and air hole.

In another mode, an insert is additionally arranged at a pre-processing barb, and the insert and a workpiece are ejected together when the mold is opened. However, the insert is removed from the workpiece in the subsequent process, and the operation is required to be performed once each forming, so that the process of removing the insert wastes labor and time and has certain danger.

In view of the above, it is necessary to develop an overlapped slider structure to solve the above problems.

[ summary of the invention ]

Accordingly, it is an object of the present invention to provide an overlapping slider structure. The overlapped slide block structure can be used for forming two adjacent barb structures at one time, is efficient and labor-saving, and does not need subsequent process treatment.

In order to achieve the above object, an overlapped slider structure of the present invention comprises:

the first sliding block body is internally provided with a plurality of accommodating grooves, a first forming part is arranged at one end of the first sliding block body, which is in contact with a product, and the first sliding block body can be connected with a first oil hydraulic cylinder;

the second sliding block bodies are just arranged in the accommodating grooves, a second forming part is arranged at one end, which is in contact with the product, of the second sliding block body, and the second sliding block bodies can be connected with a second oil hydraulic cylinder;

the guide block is inserted in the middle of the first sliding block body;

wherein the second molding part overlaps with the first molding part; when in molding, the first molding part and the second molding part simultaneously mold two adjacent structures with different directions on the product.

Preferably, the first slider body and the second slider body are respectively provided with a slider opening plate in a clamping manner on two sides.

Preferably, the overlapped slider structure further comprises a slider block inserted into the first slider body.

Preferably, one end of each second sliding block body is connected to the connecting seat; when the die is opened, the second oil hydraulic cylinder drives the second sliding block body to move by dragging the connecting seat.

Preferably, the first hydraulic cylinder and the second hydraulic cylinder each include a hydraulic cylinder side plate and a pad plate.

Preferably, the product has a structure of barbs, and the two barbs are adjacent and have different directions.

Compared with the prior art, the overlapped sliding block structure has the advantages that the smaller second sliding block body is arranged in the first sliding block body with larger volume, and the first forming part and the second forming part are overlapped, so that two adjacent barb structures on a product are formed simultaneously. The overlapped slide block structure can form two adjacent barb structures at one time, is efficient and labor-saving, and does not need subsequent other procedures.

The invention is used for forming two adjacent barbs 11 and 12 on a product, and the structure of the invention comprises:

a first slider body 100, which is internally provided with two accommodating grooves, wherein one end of the first slider body 100, which is in contact with a product 10, is provided with two first forming parts 101, and the first slider body 100 can be connected with a first oil pressure cylinder (not shown); the first molding part 101 molds the barbs 11;

the guide block 300 is inserted in the middle of the first slider body 100, connected to the template, and drives the first slider body 100 to move along a fixed direction when the template is opened and closed;

wherein the second molding part 201 overlaps with the first molding part 101; during molding, the first molding portion 101 and the second molding portion 201 simultaneously mold two adjacent barb structures on the product 10.

Preferably, a first slider stretching plate 102 is clamped at two sides of the first slider body 100, and a second slider stretching plate 202 is clamped at two sides of the second slider body 200; the slider in the middle of the slider stretching plate is clamped to the left and the right so as to ensure that the slider is demoulded along a preset track during forming and a formed product cannot be scrapped due to deviation.

Preferably, the overlapped slider structure further includes a slider block 400 inserted into the first slider body 100 for fixing the first slider body 100.

Preferably, one end of each of the two second slider bodies 200 is connected to the connecting seat 500; when the die is opened, the second oil hydraulic cylinder drives the second slider body 200 to move by dragging the connecting seat 500; the connecting seat 500 is connected to the two second slider bodies 200 at the same time, so that the two second slider bodies 200 can be driven to be simultaneously released when the mold is opened.
