Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a die-casting mold capable of preventing material damage. Background Art

[0002] A die-casting mold is a tool used to cast metal parts, completing the die-casting process on a dedicated die-casting forging machine. The basic die-casting process involves molten metal being poured into the die cavity at either a low or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools. This eliminates shrinkage defects in the blank and achieves a forged, broken grain structure within the blank. This significantly improves the blank's overall mechanical properties.

[0030] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a die-casting mold that prevents material damage, including: a fixed plate 1, a blanking protection mechanism 8 is provided at the lower end of the fixed plate 1, a die-casting plate 6 is provided above the blanking protection mechanism 8, a telescopic cylinder 3 is provided at the upper end of the fixed plate 1, and a mold 4 is fixedly installed on the telescopic end of the telescopic cylinder 3. Flexible clamping mechanisms 5 are provided on the side walls of the mold 4 at the upper, left and right positions respectively. The processing part 9 is located inside the mold 4, and the mold 4 is fitted with the die-casting plate 6. The cooperation of the fixed plate 1, the flexible clamping mechanism 5 and the blanking protection mechanism 8 can provide good protection for the processing part 9 during the demolding operation.

[0031] The blanking protection mechanism 8 includes a No. 2 telescopic rod 81, the other end of the No. 2 telescopic rod 81 is movably connected to the No. 3 telescopic rod 82, and one side of the fixed plate 1 is movably connected to the blanking plate 83. The lower end of the blanking plate 83 is penetrated by a mounting hole 85, and the movable end of the No. 3 telescopic rod 82 passes through the blanking plate 83 through the mounting hole 85. The upper end of the No. 3 telescopic rod 82 is fixedly connected to a support block 84, and one side of the No. 2 telescopic rod 81 is movably connected to the lower end of the fixed plate 1. When the No. 2 telescopic rod 81 and the No. 3 telescopic rod 82 are started, the No. 2 telescopic rod 81 contracts, thereby driving the No. 3 telescopic rod 82 to move. Because of the limiting effect of the No. 3 telescopic rod 82 and the blanking plate 83, the blanking plate 83 rotates along the connecting axis of the fixed plate 1, thereby causing one end of the blanking plate 83 to tilt downward. At this time, the telescopic end of the No. 3 telescopic rod 82 contracts into the mounting hole 85, which plays a buffering role in the discharging of the processed parts 9.

[0032] The three groups of flexible clamping mechanisms 5 all include a support frame 51, and a No. 1 telescopic rod 52 is fixedly installed inside the support frame 51. The telescopic end of the No. 1 telescopic rod 52 is fixedly connected to a flexible partition 53. By starting the three groups of No. 1 telescopic rods 52, one end of the No. 1 telescopic rod 52 is contracted, thereby driving the three groups of flexible partitions 53 to be demoulded.

[0033] The side wall of the flexible partition 53 is slidably connected to the inside of the mold 4, one side of the support frame 51 is fixed to the outer surface of the mold 4, a liquid inlet hole 7 is opened through the inside of the die-casting plate 6, the lower end of the mold 4 is slidably connected to one side of the fixed plate 1, and the upper end of the fixed plate 1 is fixedly connected to the lower end of the side plate 2. One side of the three groups of flexible partitions 53 are in contact with the side wall of the processed part 9, the mold 4 and the die-casting plate 6 fit together, and the No. 3 telescopic rod 82 first contracts and then extends, forming a closed cavity with the protrusion inside the die-casting plate 6 and the mold 4. The die-casting melt can be poured into the closed cavity of the mold 4 and the die-casting plate 6 through the liquid inlet hole 7, thereby preventing the die-casting melt from flowing out.

[0034] The technical solution provided by the present invention is as follows: first, by starting the telescopic cylinder 3, the telescopic end of the telescopic cylinder 3 drives the mold 4 to move toward the direction close to the die-casting plate 6, so that the mold 4 and the die-casting plate 6 fit together, and the third telescopic rod 82 contracts and then extends to form a closed cavity with the protrusion inside the die-casting plate 6 and the mold 4 to prevent the die-casting melt from flowing out, and then the die-casting melt is poured into the closed cavity of the mold 4 and the die-casting plate 6 through the liquid inlet hole 7 on the die-casting plate 6. After the processed part 4 is formed, one end of the telescopic cylinder 3 is shortened to drive the processed part 4 to move toward the direction close to the side plate 2. At this time, by starting the three groups of No. 1 telescopic rods 52, one end of the No. 1 telescopic rod 52 is contracted, thereby driving the three groups of flexible partitions 53 to perform demoulding, so that the demoulding operation is simple. The second telescopic rod 81 and the third telescopic rod 82 are started at the same time, the second telescopic rod 81 contracts, thereby driving the third telescopic rod 82 to move. Because of the limiting effect of the third telescopic rod 82 and the blanking plate 83, the blanking plate 83 rotates along the connecting axis of the fixed plate 1, thereby causing one end of the blanking plate 83 to tilt downward. At this time, the telescopic end of the third telescopic rod 82 contracts into the mounting hole 85, and the processed part 9 can slide along the blanking plate 83, which has a buffering effect on the discharging process of the processed part 9. Therefore, the fixed plate 1, the flexible clamping mechanism 5 and the blanking protection mechanism 8 can cooperate with each other to protect the processed part 9 during the demolding operation, thereby preventing material damage, thereby increasing the production qualification rate of the product.

[0035] The present invention encompasses any substitutions, modifications, equivalent methods, and solutions that are not within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
