Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

The first embodiment is as follows: as shown in fig. 1 to 4, the utility model discloses a mold for combined machining of a combined oil seal, which comprises a lower mold mechanism 1, an upper mold mechanism 2 and a material returning mechanism 3;

the lower die mechanism 1 comprises a base 4, a positioning shaft 7 and a positioning sleeve 9; the material returning mechanism 3 comprises a piece returning sleeve 13 and a spring 14; the upper die mechanism 2 comprises a pressing sleeve 10 and an upper cover 11; the middle of the upper end of the base 4 is provided with an installation groove, the middle of the installation groove is provided with a jack, the positioning shaft 7 is vertically arranged, the lower end of the positioning shaft is placed in the installation groove and is fixedly inserted into the jack, the spring 14, the withdrawing sleeve 13 and the positioning sleeve 9 are sequentially sleeved on the positioning shaft 7 from top to bottom, and the positioning sleeve 9 is placed on the base 4; the pressing sleeve 10 is sleeved outside the material returning mechanism 3 in a sleeved mode, the upper end of the pressing sleeve 10 is fixedly connected with the upper cover 11 through bolts, the lower end of the pressing sleeve 10 is connected with the piece returning sleeve 13 in a sliding limiting mode, a through hole is formed in the middle of the upper cover 11, the upper end of the positioning shaft 7 is tightly inserted into the through hole, and two ends of the spring 14 are abutted to the piece returning sleeve 13 and the upper cover 11 respectively.

The second embodiment is as follows: as shown in fig. 1 and 2, in the present embodiment, a threaded hole is formed in a lower end surface of the positioning shaft 7, and the positioning shaft 7 is fixedly connected to the base 4 through a nut 5 screwed into the threaded hole.

The third concrete implementation mode: as shown in fig. 1 and 2, in this embodiment, a placement groove is provided in the middle of the lower end of the base 4, the placement groove is communicated with the insertion hole, and the nut 5 is disposed in the placement groove.

The fourth concrete implementation mode: as shown in fig. 1 and 2, in this embodiment, a second embodiment or a third embodiment is further described, and a washer 6 is disposed between the nut 5 and the base 4.

The fifth concrete implementation mode: as shown in fig. 1 and 2, in the present embodiment, a gasket 8 is disposed between the positioning sleeve 9 and the base 4.

Use the utility model discloses the time, assemble upper die mechanism 2 and material returned mechanism 3 earlier. During production, the combined oil seal 15 is sleeved on the positioning shaft 7 of the lower die mechanism 1 and is placed in the positioning sleeve 9, then the upper die mechanism 2 and the material returning mechanism 3 assembly are sleeved on the outer side of the positioning shaft 7, and at the moment, the lower end of the material returning sleeve 13 is in contact with the combined oil seal 15.

Then will the utility model discloses place on stamping equipment, press through stamping equipment and move upper die mechanism 2, press hole department turn-ups structure and the 15 contacts of combination oil blanket of cover 10 lower extreme then, press to pressing the laminating of cover 10 bottom surfaces and 9 upper surfaces of position sleeve, accomplish turn-ups work. After the punching press is accomplished, will go up mold mechanism 2 and take off, owing to set up material returned mechanism 3, at the in-process that mold mechanism 2 taken off, the effort through spring 14 can make and move back a set 13 and promote combination oil blanket 15 always and be located position sleeve 9, avoids the in-process that upper mold mechanism 2 taken off, directly takes off combination oil blanket 15.

After the upper die mechanism 2 is taken down, the combined oil seal 15 is remained on the positioning shaft 7 or in the positioning sleeve 9 and is directly taken down or extruded.

From the viewpoint of optimized structure, the lower die mechanism 1 can be integrated, but this results in the product being left in the lower die mechanism 1 after being processed and inconvenient to take out. Therefore, the positioning sleeve 9 and the positioning shaft 7 are made to be separated, and the product can be smoothly taken out only by detaching the positioning sleeve 9 and the positioning shaft 7 after the product is left on the positioning sleeve 9.

The purpose of flanging is achieved by replacing the pressing sleeves 10 with different shapes, and the production of the combined leather cup is realized.
