Description

Technical Field

[0001] The utility model belongs to the technical field of casting molds, in particular to a processing mold for metal castings. Background Art

[0002] A casting mold is a mold that is preformed for casting metal parts in order to obtain the structural shape of the parts. The mold consists of at least two parts. The two parts of the mold are sealed and fitted together, and then liquid metal is injected through the casting port. After the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed;

[0003] Common castings are formed by a male mold and a female mold. Because it is a metal casting, the casting process temperature is relatively high. After the heated molten liquid metal is poured into the mold, it is cooled and formed, and then the mold is opened to take the formed parts out of the mold. During the casting process of solid parts, the center cannot directly contact the outside and cannot be cooled quickly, while the contact surface between the outside and the mold can be formed quickly. In order to improve efficiency in the actual processing process, the parts that are formed on the outside but not completely solidified on the inside will be taken out directly from the mold for secondary cooling. At this time, the mold can continue to cast, and the purpose of improving efficiency is achieved by shortening the die-casting time;

[0004] Since both the parts and the mold do not meet the cooling requirements, the parts can be cooled for a second time, while the mold will continue to work at a higher temperature. The mold temperature is high, the cooling time of the parts is also increased, and the die-casting time is increased. In this case, the mold is generally cooled by air cooling after the mold is opened, but due to the short time, the heat inside the mold cannot be effectively dissipated. If it continues to work, the high temperature will cause cracks and cracks on the mold surface, affecting the life and use of the mold. If it works intermittently, it will affect the efficiency;

[0005] In order to solve the above problems, the present application proposes a processing mold for metal castings. Utility Model Content

[0006] The purpose of the utility model is to provide a processing mold for metal castings, which solves the problems raised in the above background technology.

[0009] Furthermore, a guide sleeve is fixed on the support plate, a guide rod is fixed on the bottom of the lower die base, the guide rod penetrates and slides in the guide sleeve, and a limit block is provided at the bottom of the guide rod.

[0010] Furthermore, the support plate is fixed on the base through a vertical rod, and a lifting space for a guide rod is left, and the stripping plate is vertically fixed on the support plate.

[0011] Furthermore, a through hole for the stripper plate to move is provided inside the lower die base, and after the lower die base is located at the top, the top of the stripper plate is matched with the inner side of the lower die base.

[0012] Furthermore, the lower die seat is located directly above the support plate and is distributed parallel to the support plate, and a hydraulic cylinder is provided between the support plate and the lower die seat.

[0015] The utility model has the following beneficial effects:

[0016] The utility model provides two lower die seats to cooperate with a double-sided upper die seat. During the casting process, only one set of the lower die seat and one side of the upper die seat is in the die-casting state, while the other set is continuously cooled by the heat dissipation module. The continuous operation can not only ensure the die-casting efficiency, but also improve the die-casting efficiency and quality.

[0017] The utility model configures the lower die seat as a lifting structure and arranges a stripping plate inside the lower die seat, which can not only ensure the shape of the lower die seat but also facilitate the separation of the parts.

The guide rod 8 slides through the guide sleeve 7, and a limit block is provided at the bottom of the guide rod 8. In this embodiment, the guide sleeve 7 and the guide rod 8 not only guide but also play a role in structural reinforcement, thereby ensuring the structural stability.

[0030] Among them, the support plate 6 is fixed on the base 1 through the vertical rods, and the lifting space for the guide rod 8 is left, and the stripping plate 10 is vertically fixed on the support plate 6. In this embodiment, the vertical rods between the support plate 6 and the base 1 provide lifting space for the guide rod 8. There are multiple vertical rods to ensure the stability of the support plate 6 on the base 1.

[0031] Among them, a through hole is opened inside the lower die base 3 for the movement of the stripper plate 10. After the lower die base 3 is located at the top, the top of the stripper plate 10 coincides with the inner side of the lower die base 3. In this embodiment, when the top of the stripper plate 10 coincides with the lower die base 3, it is used for forming the parts. After the lower die base 3 descends, the parts are automatically ejected through the fixed stripper plate 10, which is convenient for removal.

[0032] Among them, the lower die base 3 is located directly above the support plate 6 and is distributed parallel to it. A hydraulic cylinder 9 is arranged between the support plate 6 and the lower die base 3. In this embodiment, the lower die base 3 is driven to rise and fall by the hydraulic cylinder 9.

After cooling and forming, the hydraulic cylinder 9 drives the lower die seat 3 to descend. In this process, the part is demoulded from the upper die seat 4 under its own weight. At this time, the demoulding plate 10 presses the part to demould from the lower die seat 3, and the material head is automatically cut off. The flip motor 12 is started to drive the upper die seat 4 to flip on the flip frame 11 to the position shown in FIG. Figure 2 In the state shown, the cooled side of the upper mold base 4 and the lower mold base 3 on the right continue to cast, and the heat dissipation module 2 works to dissipate heat for the mold that has just been opened. At the same time, the staff removes the parts from the opened mold. When the parts are cast again, the mold in the open state has met the cooling requirements, and the continuous work is repeated.
