Description

Technical Field

[0001] This utility model relates to the field of aluminum nickel cobalt magnet casting technology, and in particular to an aluminum nickel cobalt magnet casting equipment for permanent magnet chucks. Background Technology

[0002] Molding equipment for AlNiCo magnets is mainly used to produce magnet components required for permanent magnet chucks. Common molding equipment is casting equipment, which can process and produce different sizes and shapes. Molten AlNiCo alloy is poured into a mold to cool and solidify, and then heat treatment is used to optimize the crystal structure and magnetic properties.

[0003] Currently, because the magnet components of permanent magnet chucks are sheet-like structures with a central opening, the sheet-like AlNiCo magnets tend to adhere to the molding mold during the casting process, making demolding difficult. Furthermore, AlNiCo magnets need to cool naturally to room temperature after casting before they can be demolded, and the slow cooling rate at room temperature results in low molding efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an aluminum-nickel-cobalt magnet forming device for permanent magnet chucks. This device achieves cooling and demolding of the aluminum-nickel-cobalt magnets through a metal cooling pipe structure combined with a demolding template structure, thus solving the problems of slow cooling speed and difficulty in demolding of aluminum-nickel-cobalt magnets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a molding device for aluminum-nickel-cobalt magnets for permanent magnet chucks, comprising a lower mold and an upper mold fixed to the top of the lower mold. An inner mold is embedded in both the lower and upper molds. The top of the inner mold has a casting groove arranged in a rectangular array. The bottom wall of the casting groove has a recessed hole, in which a release template is inserted. A cooling metal tube is embedded in the bottom of the lower mold. The inner mold is a resin-bonded sand mold, capable of withstanding the high temperature of the nickel-cobalt magnet.

[0006] Preferably, the bottom end of the lower mold is equipped with a rectangular array of multiple bolts, and the top of each bolt passes through the upper mold and is threaded with a nut.

[0007] Preferably, the top of the upper mold has a funnel-shaped pouring hole, which is connected to a plurality of pouring grooves.

[0008] Preferably, a water storage tank is provided on one side of the lower mold, and a water inlet pipe is fixedly installed at the bottom of the side wall of the water storage tank.

[0009] Preferably, the cooling metal pipe and the water inlet pipe are fixed with interconnected water pipe joints, and the water storage tank is equipped with a water pump connected to the water inlet pipe.

[0010] Preferably, both sides of the bottom end face of the lower mold are fixed with protrusions, and the top of the inner mold is provided with a connecting groove for connecting multiple casting grooves.

[0011] Preferably, a protruding rod is fixed to the top of the demolding template, and the top of the protruding rod is inserted into the upper mold.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) This utility model has multiple casting grooves on the top of the inner mold in the lower mold, and a demolding template is inserted into the recessed hole on the bottom wall of the casting groove. After the aluminum nickel cobalt magnet is formed in the casting groove, the upper mold and the lower mold are separated. The top of the protruding rod protrudes from the top of the aluminum nickel cobalt magnet. By pulling the top of the protruding rod, the demolding template drives the aluminum nickel cobalt magnet to be demolded from the casting groove, which improves the convenience of demolding the aluminum nickel cobalt magnet.

[0014] (2) This utility model provides a water storage tank on one side of the lower mold. After the aluminum nickel cobalt magnet is cast, the water inlet pipe is fixed to the cooling metal pipe through the water pipe joint.

[0023] Example 1

[0024] like Figure 1 and Figure 3 As shown, this embodiment provides a molding device for AlNiCo magnets for permanent magnet chucks, including a lower mold 1 and an upper mold 4 fixed to the top of the lower mold 1. An inner mold 8 is embedded in both the lower mold 1 and the upper mold 4. The top of the inner mold 8 has a casting groove 16 arranged in a rectangular array. The bottom wall of the casting groove 16 has a recessed hole 12. A release template 13 is inserted into the recessed hole 12. A cooling metal tube 10 is embedded in the bottom of the lower mold 1. The inner mold 8 is a resin-bonded sand mold that can withstand the high temperature of the nickel-cobalt magnet.

[0025] The bottom of the lower mold 1 is equipped with a rectangular array of bolts 3. The top of the bolts 3 passes through the upper mold 4 and is threaded with nuts 6. The top of the upper mold 4 is provided with a funnel-shaped pouring hole 5, which is connected to a plurality of pouring grooves 16. A water storage tank 7 is provided on one side of the lower mold 1. A water inlet pipe 2 is fixedly installed on the bottom of the side wall of the water storage tank 7. A water pipe connector 11 is fixedly connected to the cooling metal pipe 10 and the water inlet pipe 2. A water pump connected to the water inlet pipe 2 is embedded in the water storage tank 7. The water pipe connector 11 fixes the water inlet pipe 2 to the cooling metal pipe 10. The water pump in the water storage tank 7 causes cooling water to enter the cooling metal pipe 10 along the water inlet pipe 2, and after cooling the lower mold 1 and the inner mold 8, it is discharged from the cooling metal pipe 10. The cooling metal pipe 10 improves the cooling efficiency of the aluminum nickel cobalt magnet in the mold.

[0026] Example 2

[0027] like Figure 2 and Figure 4 As shown, the components that are the same as or corresponding to those in Embodiment 1 are referred to by the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that: both sides of the bottom end face of the lower mold 1 are fixed with protrusions 9, the top of the inner mold 8 is provided with a connecting groove 15 for connecting multiple casting grooves 16, the top of the demolding template 13 is fixed with a protruding rod 14, and the top of the protruding rod 14 fits into the upper mold 4. After the AlNiCo magnet is formed in the casting groove 16, the upper mold 4 is separated from the lower mold 1. The top of the protruding rod 14 protrudes from the top of the AlNiCo magnet. By pulling the protruding tops of the multiple protruding rods 14, the demolding template 13 causes the AlNiCo magnet to be demolded from the casting groove 16.

[0028] Work steps

[0029] Step 1: During use, the bolt 3 at the bottom of the lower mold 1 passes through the threaded sleeve nut 6 of the upper mold 4, fixing the upper mold 4 and the lower mold 1 together. The protruding rod 14 is inserted into the upper mold 4. Molten AlNiCo magnets are poured into the casting hole 5, which has a perforated structure. After the AlNiCo magnets are cast, the water inlet pipe 2 is fixed to the cooling metal pipe 10 through the water pipe connector 11. The water pump in the water tank 7 drives the cooling water along the water inlet pipe 2 into the cooling metal pipe 10, cooling the lower mold 1 and the inner mold 8 before draining it out of the cooling metal pipe 10. The cooling efficiency of the AlNiCo magnet in the mold is improved by the cooling metal pipe 10. After the AlNiCo magnet is formed in the casting tank 16, the nut 6 is unscrewed to separate the upper mold 4 from the lower mold 1. The top of the protruding rod 14 protrudes from the top of the AlNiCo magnet. Pulling the top of the protruding rod 14 causes the demolding plate 13 to demold the AlNiCo magnet from the casting tank 16. After demolding, the protrusions formed in the connecting groove 15 with the AlNiCo magnet are cut off, and the AlNiCo magnet is polished so that it can be processed in subsequent steps.
