Description

Technical Field

[0001] The utility model relates to the technical field of mold preheating devices, in particular to a continuous mold preheating device. Background Art

[0002] In the manufacturing process of zinc-aluminum anodes, casting molds are used for casting and molding. The casting molds need to be preheated before use. Preheating the mold can, on the one hand, prevent the high-temperature liquid metal from causing "thermal shock" to the mold and causing premature thermal fatigue failure, thereby extending the service life of the die-casting mold; on the other hand, it can prevent the liquid metal from losing fluidity quickly due to quenching in the mold, so that the casting cannot be filled smoothly, resulting in defects such as insufficient casting, cold shut, and "freezing", or even if it is formed, the linear shrinkage due to quenching increases, causing defects such as cracks in the casting or increased surface roughness.

[0003] When using some existing mold preheating devices, the molds need to be stacked on a disc, and after the preheating is completed, the molds need to be taken out one by one manually, which is time-consuming and labor-intensive to operate and is not conducive to continuous operation.

[0004] For example, a mold preheating device that is easy to operate is disclosed with the announcement number CN219449905U. This patent is capable of placing molds through a disc by providing a rotating component. The discs are of different sizes and can hold molds of different sizes. Multiple groups of molds can be placed at the same time, which can increase the functionality of the device. The bottom is set as a hollow frame to ensure all-round preheating of the mold, so that it is heated evenly and improves the preheating effect of the device.

[0005] However, when the mold preheating device of the patent is used, the molds need to be stacked on a disc, and after the preheating is completed, the molds need to be taken out one by one manually, which is time-consuming and labor-intensive to operate and is not conducive to continuous operation.

[0006] Therefore, it is necessary to invent a continuous mold preheating device to solve the above problems. Utility Model Content

[0014] Preferably, the bottom end of the shielding door curtain is close to the plate chain conveyor and does not contact the plate chain conveyor, and the shielding door curtain is made of heat-resistant rubber material.

[0015] The shielding curtain can not only seal the two ends of the U-shaped heating furnace to a certain extent to prevent heat loss, but also will not hinder the transportation of the mold.
