Description

Technical Field

[0001] This invention relates to the field of casting technology, specifically to a casting method and casting apparatus for automobile castings. Background Technology

[0002] Casting, also known as "casting," is the production process of melting metal and pouring it into a mold to form an object of a specific shape. The mold into which molten metal is poured is called a casting mold. After the molten metal solidifies in the cavity of the casting mold, it becomes a casting of a specific shape.

[0003] In the existing technology, the casting process of automobile castings requires melting metal, then pouring the molten metal into a prepared mold, and shaping the metal through the mold. After the metal solidifies, the shaped part can be obtained.

[0004] In the existing sand box used for molding, the operator needs to place the upper box on the lower box during use. This requires hoisting equipment to lift the upper box and place it on the lower box. Due to the large weight of the upper box, the operator cannot properly align the upper box with the lower box. Summary of the Invention

[0005] The purpose of this invention is to provide a casting method and casting apparatus for automobile castings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a casting method for automobile castings, comprising:

[0007] Step 1: Determine the position, lift the upper mold so that the extension rod is inserted into the insertion slot, and determine the basic position of the upper mold. When the upper mold descends, the extension rod pushes the adjusting rod, so that the adjusting rod pushes the insertion rod, so that the insertion rod enters the interior of the second fixed rod. The adjusting rod drives the connecting rod to move, and the connecting rod drives the cleaning block to move, so that the cleaning block moves on the surface of the limiting block. The cleaning block cleans the dust on the surface of the limiting block, and the cleaning strip is inserted into the interior of the limiting groove under the limit of the inclined plate, so that the cleaning strip cleans the interior of the limiting groove.

[0008] Step 2: Accurate positioning. After the cleaning strip is inserted into the limiting groove, the swing rod rotates around the pivot under the pull of the spring piece, so that the swing rod is inserted into the slot, so that the cleaning strip is away from the upper and lower molds. The limiting block is inserted into the limiting groove, and the position of the upper and lower molds is determined, ensuring that the top of the upper mold is facing the top of the lower mold. Molten metal is injected into the upper and lower molds through the injection port.

[0009] A casting apparatus for realizing a method of casting automobile castings has an injection port at the top of the upper mold, the interior of the upper mold is empty, a lower mold is provided at the bottom of the upper mold, the interior of the lower mold is empty, a second fixing rod is fixed on the surface of the upper mold, a connecting rod is inserted into the bottom of the second fixing rod, the connecting rod can move inside the second fixing rod, and a limit strip is provided on the surface of the connecting rod, the limit strip is inserted into the interior of the second fixing rod.

[0010] Preferably, a spring is fixed inside the second fixing rod. One end of the spring is connected to the inside of the second fixing rod, and the other end is connected to the end of the plug rod. An adjusting rod is plugged into the other end of the plug rod. A limit strip is provided on the surface of the adjusting rod. A spring is provided inside the plug rod. The other end of the spring is connected to the end of the adjusting rod. After the adjusting rod is pulled out from the inside of the plug rod, the limit strip moves with the adjusting rod, and the adjusting rod can rotate. The spring connects the inside of the plug rod and the end of the adjusting rod.

[0011] Preferably, a connecting rod is fixed to the end of the adjusting rod, and a cleaning block is fixed to the end of the connecting rod. The cleaning block and the connecting rod move with the adjusting rod. A limit block is fixed to the surface of the upper mold. The cleaning block is located on the surface of the limit block, and the surface of the cleaning block is in contact with the surface of the limit block.

[0012] Preferably, the bottom of the limiting block is hinged to a swing rod via a pivot, a support rod is fixed to the surface of the swing rod, a cleaning strip is fixed to the surface of the support rod, a spring is fixed to the surface of the swing rod, and the other end of the spring is connected to the surface of the limiting block.

[0013] Preferably, the surface of the lower mold is fixed with a limiting groove, and the surface of the limiting groove is fixed with an inclined plate. When the limiting block descends, the inclined plate supports the surface of the cleaning strip, and the cleaning strip is inserted into the interior of the limiting groove. The surface of the limiting groove is provided with a slot, the width of which is consistent with the diameter of the swing rod, and the swing rod can be inserted into the slot.

[0014] Preferably, the surface of the lower mold is fixed with a first fixing rod, and multiple sets of the first fixing rod are provided. An extension rod is fixed to the end of the first fixing rod, and the diameter of the extension rod is smaller than the diameter of the first fixing rod. The surface of the upper mold is fixed with an insertion groove, and the inner diameter of the insertion groove is the same as the diameter of the extension rod. The extension rod can be inserted into the inside of the insertion groove.

[0015] Preferably, the adjusting rod is located at the top of the insertion slot, and the extension rod is inserted into the insertion slot and held against the surface of the adjusting rod, so that the adjusting rod can move.

[0016] Preferably, the limiting block can be inserted into the inside of the limiting groove, and the shape of the limiting block is consistent with the shape inside the limiting groove. The diameter of the cleaning strip is larger than the diameter inside the limiting groove, and multiple sets of support rods are provided. The support rods are flexible and can be bent.

[0017] Preferably, there are two sets of limiting blocks and limiting grooves, with the two sets of limiting blocks and limiting grooves located at both ends of the upper mold and the lower mold, respectively.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The present invention proposes an upper mold lifting mechanism where an extension rod is inserted into the insertion slot to determine the basic position of the upper mold. When the upper mold descends, the extension rod pushes the adjusting rod, which in turn pushes the insertion rod, causing the insertion rod to enter the interior of the second fixing rod. The adjusting rod drives the connecting rod to move, which in turn drives the cleaning block to move. This causes the cleaning block to move on the surface of the limiting block, where it cleans the dust from the surface of the limiting block. The cleaning strip, under the limiting of the inclined plate, is inserted into the limiting groove, cleaning the interior of the limiting groove. After the cleaning strip is inserted into the limiting groove, the swing rod rotates around the pivot under the pull of the spring plate, inserting into the slot and moving the cleaning strip away from the upper and lower molds. The limiting block is then inserted into the limiting groove, determining the positions of the upper and lower molds and ensuring that the top of the upper mold faces the top of the lower mold. Molten metal is then injected into the interior of the upper and lower molds through the injection port. Attached Figure Description
