Description

Technical Field

[0001] The utility model relates to the field of automobile moulds, in particular to a four-cavity double-sequence mold-joining mould for flanging and side flanging shaping of left and right parts of a drainage trough. Background Art

[0002] The body drain groove is an important part of the body structure. It is mainly arranged on the lower side of the front section of the windshield in front of the engine compartment, including the symmetrically arranged left drain groove and right drain groove. The main function of the drain groove is to guide the rainwater on the body along the drain groove to the outside of the car, thereby preventing the water from entering the interior of the car body and the body sheet metal structure, which helps to keep the interior space dry and comfortable, and at the same time prevents the body sheet metal from rusting prematurely under the action of rain.

[0003] The drain gutter is made by punching out a stamping die, and usually requires flanging and side flanging processes to stamp it into a groove that can be connected to the car body. The current flanging and side flanging processes are usually separately set in two sets of dies, and it is stamped and flanging into shape through two sets of dies and two processes. In addition, one set of dies needs to be designed for the left drain gutter and another set of dies needs to be designed for the right drain gutter. The combination of these dies forms a stamping line to complete the stamping production of the drain gutter. This combination requires a large number of dies, high equipment costs, and more processes, which is not conducive to improving efficiency and needs to be improved. Utility Model Content

The two fixed flanging upper mold cores correspond to the two flanging lower mold cores respectively, and a sliding cavity is provided on the base outside the flanging upper mold core A 111, in which an upper sliding seat A 11 is installed, and a side flanging upper mold core A 131 is provided on the surface of the upper sliding seat A 11, and a sliding cavity is provided on the base outside the flanging upper mold core B 121, in which an upper sliding seat B 12 is installed, and a side flanging upper mold core B 132 is provided on the surface of the upper sliding seat B 12, and the two fixed flanging lower mold cores correspond to the two flanging upper mold cores respectively.

[0024] The ends of the flanging lower mold core A 211, the flanging lower mold core B 212, the side flanging lower mold core A 221 and the side flanging lower mold core B 222 are all provided with positioning pins 23. After the workpiece is placed on the lower mold core, the round hole at its end is inserted into the positioning pin 23 to ensure that the workpiece is in an accurate stamping position on the mold core.

[0025] A through hole 24 is provided in the mold core on one side of the locating pin 23, and a telescopic push rod is provided in the mold cavity below the through hole 24. A telescopic ejector rod 25 on the telescopic push rod extends into the through hole 24. The telescopic push rod drives the ejector rod to extend or retract in the through hole 24.

A slider 41 is provided on the outer side surface of the upper sliding seat, and a gas spring 42 is provided on the bottom surface of the upper sliding seat. The slider 41 provides sliding support for the side surface of the sliding seat to prevent the sliding friction from wearing the sliding seat. The slider 41 can be replaced after it is worn. The gas spring 42 provides buffer support for the sliding seat to absorb the impact force generated on the mold core when the mold is closed.

[0027] A limit plate 43 is provided at the sliding cavity port around the lower sliding seat 21, and a limit boss 44 is correspondingly provided on the outer side surface of the lower sliding seat 21. The limit boss 44 and the limit plate 43 are used to provide limitation for the lower mold core and control its sliding stroke.

A set of molds can be closed twice to realize the flanging and side flanging processes of the left and right parts of the drainage trough, which reduces the processing and manufacturing processes of the two workpieces and has higher processing efficiency. In the process of mold closing and stamping, the upper sliding seat in the upper mold seat and the lower sliding seat 21 in the lower mold seat slide synchronously to compress the gas spring 42, and a sliding buffer mechanism is formed in the middle and both sides of the mold to improve the overall force balance of the mold, so as to improve the stamping quality of the workpiece.
