Description

Technical Field

[0001] The utility model belongs to the technical field of stamping dies, and in particular relates to a stamping die for a damping hinge of a display cabinet. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] Display cabinets are widely used nowadays. Damping hinges are needed to connect the display cabinets when they are installed. Damping hinges are a kind of hydraulic buffer hinges that utilize the buffering properties of liquid and have ideal buffering effects. The door starts to close slowly at 60°, reducing the impact force and forming a comfortable damping hinge effect when closing.

[0004] Damping hinges are generally stamped by stamping dies. When in use, the bottom die of the stamping die generally needs to be fixed to the die base with bolts. Due to the differences in specifications of damping hinges, the shapes of the bottom die are also different. Therefore, the bottom die usually needs to be installed on a matching die base, which increases the cost of use. Utility Model Content

[0005] The utility model aims to provide a display cabinet damping hinge stamping die to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a display cabinet damping hinge stamping die, comprising a bottom die and a die base, wherein the four corners of the bottom die are provided with first connecting holes, and two mounting rods are slidably installed inside the die base, the two mounting rods are symmetrically distributed, and mounting blocks are slidably installed on the two mounting rods, and the top of the mounting blocks is provided with second connecting holes;

[0007] Slide grooves are provided on both sides of the bottom mold, and both ends of the mounting rods are slidably connected in the slide grooves. A bidirectional screw is rotatably installed in one of the slide grooves, and one end of the two mounting rods is sleeved on the bidirectional screw and threadedly connected with the bidirectional screw. A positioning bolt is inserted into one side of the mounting block, and the positioning bolt abuts against the surface of the mounting rod.

[0008] As a preferred embodiment, there are at least two mounting blocks on each mounting rod.

[0009] As a preferred embodiment, a knob is provided at one end of the mold base, and the knob is fixedly connected to one end of the bidirectional screw.

[0010] As a preferred embodiment, a limiting rod is fixedly installed in another of the sliding grooves, and the other end of the installation rod is slidably sleeved on the limiting rod.

[0011] As a preferred embodiment, a dovetail slide rail is provided on the top surface of the mounting rod, and a dovetail groove matched with the dovetail slide rail is provided on the bottom of the mounting block.

[0012] As a preferred embodiment, grooves are provided at the four corners of the mold base, and mounting holes are provided at the bottom of the grooves.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The damping hinge stamping die of the display cabinet is provided with a slide groove, a bidirectional screw, a positioning bolt, a knob and a limit rod. When facing bottom molds of different specifications, since the positions of the first connecting holes of the bottom molds are different, the knob can be rotated first to make the knob drive the bidirectional screw to rotate, so that the bidirectional screw drives the two mounting rods to move closer to or away from each other, and the spacing between the two mounting rods is adjusted. Then, the positioning bolt is loosened, and the mounting block is slid on the mounting rod until it is suitable, so that the second connecting hole of the mounting block is aligned with the first connecting hole, and then the positioning bolt is tightened to fix the mounting block. The position of the second connecting hole can be adjusted, and bottom molds of different specifications can be fixed conveniently without replacing the mold base, thereby reducing the use cost.

[0015] The display cabinet damping hinge stamping die is provided with a mounting rod, a mounting block and a second connecting hole. When installing a bottom die, the bottom die only needs to be placed on a die base, and after the first connecting hole on the bottom die is aligned with the second connecting hole, bolts can be inserted into the first connecting hole and the second connecting hole to install and fix the bottom die.
