Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile parts mould. Background Art

[0002] A mold is a tool that, under the action of external force, transforms a blank into a part with a specific shape and size. In the process of processing automotive sheet metal parts, injection molding, blow molding, extrusion, die-casting and stamping are usually used to process them with the help of molds. The sheet metal processing technology is one of the automotive parts processing technologies.

[0003] After the automobile sheet metal parts are processed and formed, the workpiece is sunken inside the die due to the stamping process. It is usually taken out manually using tools. However, since the workpiece is embedded in the die, it is very easy to damage the workpiece during the removal process, and even cause deformation to the workpiece, affecting the processing qualification rate of the workpiece. Utility Model Content

[0004] The utility model aims to provide an automobile parts mold to solve the problem in the background art that the workpiece is easily damaged or even deformed during the removal process due to the engagement between the workpiece and the concave mold, thereby affecting the processing qualification rate of the workpiece.

[0006] Preferably, a protective frame is fixedly connected to the upper surface of the operating table, a support rod is fixedly connected to the upper surface of the protective frame, a connecting frame is fixedly connected to the upper surface of the support rod, a bracket is fixedly connected to the upper surface of the operating table on the side close to the protective frame, a hydraulic cylinder is fixedly connected to the upper surface of the bracket, a hydraulic rod is connected to the output shaft of the hydraulic cylinder, a buffer spring is fixedly connected to the inner side of the hydraulic rod, a connecting rod is fixedly connected to the lower surface of the buffer spring, a connecting rod is fixedly connected to the lower surface of the connecting rod, a connecting plate is fixedly connected to the lower surface of the connecting plate, and a lower pressure plate is fixedly connected to the lower surface of the connecting plate.

[0007] Preferably, the connecting groove is a rectangular groove, the retaining block is a wedge-shaped block, cylindrical grooves are opened on both sides of the operating table, and the fixing rod is slidably connected to the inner side of the groove. Its function is to press the two sets of fixing rods so that the retaining block slides on the inner side of the connecting groove into the die, thereby pushing the workpiece out of the die, making it convenient to remove the workpiece from the die.

[0008] Preferably, the slide groove is a rectangular groove, and the slider is slidably connected to the inner side of the slide groove. Its function is that when the two sets of fixing rods are pressed, the slider slides synchronously on the inner side of the slide groove to lengthen the compression spring.

[0009] Preferably, the compression spring is in a spiral shape, and the compression spring is fixedly connected between the inner side of the slide groove and the slider. The connecting groove, the stop block, the fixing rod, the slider, the slide groove and the compression spring are all in two groups. Their function is to stretch the compression spring and then release the fixing rod so that the stop block, the fixing rod and the slider are reset under the elastic action of the compression spring.

[0010] Preferably, the hydraulic rod and the connecting rod are both rod-shaped, the inner side of the lower end of the hydraulic rod is hollow, and the connecting rod is slidably connected to the inner side of the hydraulic rod. Its function is to start the hydraulic cylinder to press the hydraulic rod downward, thereby driving the connecting rod, the connecting plate and the lower pressure plate to press down, thereby pressurizing the workpiece.

[0011] Preferably, the buffer spring is in a spiral shape and is fixedly connected between the connecting rod and the inner side of the hydraulic rod. Its function is that when the workpiece is pressurized, since the buffer spring is fixedly connected between the inner side of the hydraulic rod and the connecting rod, when pressurized, the buffer spring will shrink due to excessive pressure, thereby buffering the downward pressure and preventing excessive pressure from damaging the workpiece and the device.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The push block is slidably connected to the inner side of the connecting groove. When the workpiece is engaged with the die, the two sets of fixing rods are pressed to make the slider slide on the inner side of the slide groove, thereby stretching the compression spring. At the same time, the push block slides on the inner side of the connecting groove into the die, so that the workpiece can be pushed up from the bottom of the die, so that the workpiece can be separated from the die, thereby facilitating the removal of the workpiece after processing and forming. When the two sets of fixing rods are released, the slider is reset under the elastic action of the compression spring, thereby driving the push block to reset, so that the next set of workpieces can be processed.

[0014] By starting the hydraulic cylinder, the hydraulic rod is pressed down, thereby driving the connecting rod, the connecting plate and the lower pressure plate to be pressed down, and the workpiece is pressurized. Since the buffer spring is fixedly connected between the inner side of the hydraulic rod and the connecting rod, when the pressure is applied, the buffer spring will shrink due to excessive pressure, thereby buffering the downward pressure and preventing excessive pressure from damaging the workpiece and the device.
