Problems solved by technology

[0004] Die-casting molds in the prior art are often not easy to demould during die-casting. Secondly, if they are not used for a long time, they need to be heated by a given template through an external device. Therefore, a die-casting mold for cast aluminum rotor and its die-casting process are designed to optimize the above problems

Embodiment 1

[0031] Such as Figure 1-Figure 5 As shown, a cast aluminum rotor die-casting mold provided in this embodiment includes a base 11 and third buffer components 10 installed on the top of the base 11 and distributed at equal intervals. A U-shaped seat 19 is installed on the top of the third buffer component 10 . Limiting chute 13 is all opened at the bottom four corners of U-shaped seat 19 inner sides, and the inboard of limiting chute 13 is equipped with first cushioning assembly 31, and U-shaped seat 19 bottom middle positions are equipped with fixed block 22, and the first buffering assembly 31 is hinged with a hinged rod 21 away from the inside wall of the limit chute 13, and the end of the hinged rod 21 away from the first buffer assembly 31 is hinged with a sliding top block 20, and the top of the sliding top block 20 is equipped with a sliding limit plate 29, U-shaped The top of seat 19 inner side is equipped with limit slide rail 30, and the inboard of limit slide rail 30...

Embodiment 2

[0042] A die-casting process of a cast aluminum rotor die-casting mold, comprising the following steps:

[0043] Step 1: spraying release liquid through the inner side of the downward mold groove 8;

[0044] Step 2: heating the electric heating plate 27 by starting the electric heater 23, and preheating the fixed template 7 through the electric heating plate 27;

[0045] Step 3: Start the electro-hydraulic cylinder 9 to drive the movable template 1 to move downwards so that the upper mold groove 2 and the lower mold groove 8 are engaged;

[0046] Step 4: Press and hold the fixed template 7 by the movable template 1 to drive the compression of the second buffer assembly 28 and the third buffer assembly 10, and drive the sliding top block 20 to move downward;

[0047] Step 5: The hinged rod 21 is driven by the downward movement of the sliding top block 20 , and the first buffer component 31 is pushed by the hinged rod 21 for further buffering.

Abstract

The invention discloses a cast-aluminum rotor die-casting die and a die-casting process thereof and belongs to the technical field of die-casting dies. The mould is characterized in that demolding liquid is sprayed to the inner side of a lower mold groove, an electric heating plate is electrically heated by starting an electric heater, a fixed mold plate is preheated through the electric heating plate, an electric hydraulic cylinder is started to drive a movable mold plate to move downwards, so an upper mold groove is clamped with the lower mold groove, the fixed mold plate is pressed by the movable mold plate to drive a second buffer assembly and a third buffer assembly to compress, a sliding top block is driven to move downwards, the sliding top block moves downwards to drive a hinge rod, a first buffer assembly is pushed by the hinge rod to perform further buffer, so demolding is facilitated, the movable mold plate and the fixed mold plate are attached more firmly through multiple buffer assemblies during pressing, liquid leakage is avoided, better preheating can be achieved through the electric heating assembly, and better mold fixing is achieved through a semiconductor refrigerator.

Description

technical field [0001] The invention relates to a die-casting die, in particular to a die-casting die for a cast aluminum rotor and a die-casting process thereof, belonging to the technical field of die-casting dies. Background technique [0002] Die-casting mold is a method of casting liquid die forging, a process completed on a special die-casting die forging machine, its basic process is: the metal liquid is cast into the cavity of the mold at low or high speed, and the mold has The active cavity surface, which is pressurized with the cooling process of the molten metal, not only eliminates the shrinkage cavity and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state, and the comprehensive mechanical properties of the blank are significantly improved. improve. [0003] Die-casting molds are the three major elements of die-casting production, none of which can be dispensed with. The so-called die-ca...
