Description

Technical Field

[0001] This utility model relates to the field of metal casting technology, and in particular to a heat preservation furnace for molten metal. Background Technology

[0002] Die casting is a metal casting process characterized by applying high pressure to molten metal within a mold cavity. The mold is typically made of a high-strength alloy, and the process is somewhat similar to injection molding. Most die castings are iron-free, containing elements such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, either a cold chamber die casting machine or a hot chamber die casting machine is required.

[0003] During die casting, the molten metal is first poured into a heat-insulating tank, then a forklift is used to transport the tank to the furnace body. The solution in the tank is then poured into the furnace body, and a scooping machine scoops the solution from the furnace body into the injection chamber for injection die casting. However, the furnace body's feed inlet is relatively small, and pouring the solution into the furnace body using a forklift requires a high level of skill. During the pouring process, the solution may spill out, resulting in material waste and safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a heat preservation furnace for molten metal, which has the advantage of preventing the molten metal from spilling out of the furnace when it is introduced into the furnace.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A heat preservation furnace for molten metal includes a furnace body with a stepped upper surface. A feed inlet is located on the lower side of the stepped surface. Vertical support bars are fixedly connected to both sides of the feed inlet. A horizontal stop bar is fixedly connected to the upper end of each support bar, with the two stop bars positioned between the two support bars. A support plate is fixedly connected to the upper surface of the furnace body near the feed inlet, extending to the outer side of the upper part of the furnace body. Side plates are integrally formed on both sides of the support plate, with one outer side of the support plate inclined upwards. A boat-shaped hopper is placed above the furnace body, with its bottom inclined. The hopper is located between the stop bar and the support plate, with both sides of the upper opening of the hopper contacting the stop bar and the bottom of the hopper contacting the support plate. One end of the hopper abuts against the side wall of the stepped surface of the furnace body. A discharge port is located at the bottom of the inclined surface of the hopper, aligned with the feed inlet of the furnace body.

[0007] Using the above technical solution, the forklift transports the insulated tank containing molten metal to the side of the furnace, lifts the insulated tank so that its opening is positioned appropriately above the hopper opening, and then rotates the insulated tank to pour the molten metal inside into the hopper. The molten metal flows along the inner wall of the hopper through the hopper outlet and the insulated tank inlet into the insulated tank. By expanding the area of ​​the furnace inlet through the hopper, it is possible to prevent spillage of the molten metal from the insulated tank when the forklift pours it into the furnace, thus avoiding waste and safety hazards.

[0008] Preferably, a chain conveyor is provided next to the furnace body, and the chain conveyor is located below the part of the furnace body where the hopper is located on the outer side.

[0009] Using the above technical solution, the forklift first places the insulation container on the chain conveyor, which then transports the container towards the furnace. When the container hits the hopper above the chain conveyor, it is blocked and stops moving forward. The forklift then moves to the container, lifts it up, and pours the solution into the hopper. This prevents the forklift from being affected by external factors while transporting the molten metal to the furnace, which could cause the solution to spill from the opening of the insulation container, thus avoiding waste and safety hazards.

[0010] Preferably, the chain conveyor is fixedly connected to vertical support frames on both sides, and also includes baffles. The baffles are horizontally located below the hopper and above the support frames, and are fixedly connected to the tops of the two support frames.

[0011] Using the above technical solution, the insulation tank stops when it hits the baffle, preventing the insulation pipe from directly hitting the hopper, causing the hopper to move and affecting the flow of the solution into the furnace.

[0012] Preferably, one end of the stop bar is fixedly connected to a stop block, the stop bar is threaded near the stop block, and the stop bar is threadedly connected to a nut. The stop bar passes through the support bar and is slidably connected to it. The nut and the stop block are respectively located on both sides of the support bar and in contact.

[0013] Using the above technical solution, the nut is turned off the stop bar, and then the stop bar is removed from the support bar, which facilitates the installation and disassembly of the hopper.

[0014] Preferably, the top edge of the baffle is integrally formed with a surrounding rim.

[0015] The above technical solution is used to block the molten metal that overflows and splashes from the hopper, preventing it from falling onto the chain conveyor. Attached Figure Description

Nuts and the stop block are respectively located on both sides of the support rod 2, and the stop rod 3 is threaded with nuts. A support plate 4 is fixedly connected to the upper surface of the furnace body 1 near the feed inlet. The support plate 4 extends to the outer side of the upper part of the furnace body 1. Side plates 5 are integrally formed on both sides of the support plate 4, with the outer side of the support plate 4 facing upwards. The furnace body 1 is tilted, and a boat-shaped hopper 6 is placed on top of it. The bottom of the hopper 6 is tilted and it is located between the baffle 3 and the support plate 4. The two sides of the upper opening of the hopper 6 are in contact with the baffle 3, and the bottom of the hopper 6 is in contact with the support plate 4. One end of the hopper 6 is against the side wall of the step of the furnace body 1. The bottom of the sloping surface of the hopper 6 is provided with a discharge port, which is aligned with the feed port of the furnace body 1. A chain conveyor 7 is provided next to the furnace body 1. The chain conveyor 7 is located below the outer part of the furnace body 1 where the hopper 6 is located. Vertical support frames 8 are fixedly connected to both sides of the chain conveyor 7. It also includes a baffle 9.

[0023] Working principle: The forklift first places the insulated tank containing molten metal on the chain conveyor 7. The chain conveyor 7 transports the insulated tank to the furnace body 1. The insulated tank hits the baffle 9 and is stopped by the baffle 9, stopping its forward movement. Then the forklift moves to the insulated tank, picks it up, and drives the insulated tank to rise. When the opening of the insulated tank rises to an appropriate position above the opening of the hopper 6, the insulated tank is rotated, and the solution inside is poured into the hopper 6. The solution flows along the inner wall of the hopper 6 through the discharge port of the hopper 6 and the inlet of the insulated tank into the insulated tank. The hopper 6 expands the area of ​​the inlet of the furnace body 1, which can prevent the molten metal in the insulated tank from spilling when the forklift pours it into the furnace body 1, thus preventing waste and safety hazards.
