Description

Technical Field

[0001] The utility model relates to the technical field of die sets, in particular to a die set convenient for unloading workpieces. Background Technique

[0002] A die set is the support of a mold. For example, the part on a die-casting machine that combines and fixes each part of the mold according to certain rules and positions and enables the mold to be installed on the die-casting machine for work is called a die set, which is composed of a pushing mechanism, a guiding mechanism, a pre-resetting mechanism, die feet pads, and a base plate.

[0003] Chinese Patent Application No.: 201922475061.4 proposed "a die set convenient for unloading workpieces". It avoids workpieces sticking to the punch through the elastic force of a unloading spring, and then a hydraulic cylinder pushes a push plate to push the formed mold out of the die set. However, it has certain deficiencies. When unloading, it usually pushes the formed mold out from the top of the die set. Since some formed molds are closely attached and their surfaces are too smooth, applying a lateral external force from the top of the die set cannot take out the formed mold, and even may cause damage to the mold, having certain limitations. Content of the Utility Model

The exhaust pipe 10 is located between the air extraction pump and the connecting groove. A control valve is installed on the outer wall of the exhaust pipe 10. A power supply battery is installed on the top of the bottom plate 1. The air extraction pump is connected to the power supply battery through a wire. An installation frame 11 is welded to one end of the top outer wall of the bottom plate 1. The installation frame 11 is of an "L" - shaped structure. An electric telescopic rod 12 is installed on the bottom outer wall of the installation frame 11. The end of the electric telescopic rod 12 is connected to an installation disc. An upper mold base 13 is installed on the installation disc through bolts, and the upper mold base 13 is adapted to the lower mold base 3.

[0022] With the above - mentioned structure: During operation, the lower mold base 3 is fixed in the installation groove 2, and then the upper mold base 13 is connected to the installation disc. After the mold forming work is completed, the upper mold base 13 rises. At this time, air is inflated into the unloading groove 4 through the air inlet pipe 9.

At this time, the control block 15 advances under the elastic force of the fixing spring 17, and the limiting pin 16 is inserted into the limiting hole of the lower die holder 3 to fix the lower die holder 3, which is convenient for the installation and disassembly of the lower die holder 3.

[0024] The working principle of this utility model:

[0025] During work, the lower die holder 3 is fixed in the installation groove 2, and then the upper die holder 13 is connected to the installation disc. After the die forming work is completed, the upper die holder 13 rises. At this time, air is inflated into the discharge groove 4 through the air inlet pipe 9. As the gas in the discharge groove 4 increases, the discharge block 6 is gradually pushed up, thereby pushing up the material inside the lower die holder 3, which is convenient for discharging the lower die holder 3. After discharging is completed, the air pump is turned off, and the air inside the discharge groove 4 is discharged through the exhaust pipe 10. As the air is discharged, the support spring 7 gradually returns to its original state and pulls the discharge block 6 back to its original position.
