Description

Technical Field

[0001] This utility model relates to a casting mold, specifically a wheel hub casting mold with a cooling device, belonging to the field of wheel hub casting technology. Background Technology

[0002] A wheel hub is the rotating part of the wheel, connected to the inner rim of the tire by a column. It's the metal component that supports the tire and is mounted on the axle. Wheel hubs come in many varieties depending on their diameter, width, forming method, and material. During production, wheel hubs are manufactured using casting molds to complete their shape. Aluminum alloy wheels stand out in the automotive industry due to their advantages such as light weight, rapid heat dissipation, good shock absorption, long lifespan, and good balance.

[0003] However, during the casting process of wheel hubs, the relatively complex external structure of the wheel hubs makes it difficult for the heat inside the mold to dissipate, resulting in a slow cooling rate of the wheel hub castings, which in turn hinders the improvement of the casting effect. Utility Model Content

[0004] The purpose of this utility model is to provide a wheel hub casting mold with a cooling device to solve the above problems. When the upper mold of the mold is engaged with the first lower mold and the second lower mold, water is discharged into the cooling tank through the liquid inlet pipe and then discharged through the liquid outlet pipe. This can cool the wheel hub casting part and circulate the water in the cooling tank at the same time, which is beneficial to improving the cooling effect.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a wheel hub casting mold with a cooling device, including an operating table, a fixing mechanism installed on the operating table, a casting mechanism and an ejection mechanism sliding on the fixing mechanism, the casting mechanism including a fixed seat and a first hydraulic rod, two fixed seats symmetrically fixedly connected to the operating table, the first hydraulic rods fixedly installed on the fixed seats, the telescopic ends of the two first hydraulic rods respectively fixedly connected to a first lower mold and a second lower mold, a drain pipe, an inlet pipe and a sealing plate fixedly installed on the first lower mold and a cooling groove provided on the first lower mold and the second lower mold.

[0007] Preferably, the fixed base is located at the top of the operating table, and the two first hydraulic rods are symmetrically arranged on the side wall of the fixed base.

[0008] Preferably, the first lower mold and the second lower mold are engaged and connected, and the sealing plate is arranged in an arc-shaped structure.

[0009] Preferably, the fixing mechanism includes a support rod and a bottom mold. Two sets of support rods are installed on the operating table. The bottom mold is engaged with the support rod, and a support seat is fixedly connected to the support rod.

[0010] Preferably, the support base is fixedly connected to the operating table, and the two sets of support bases are arranged symmetrically.

[0011] Preferably, the first lower mold, the second lower mold, and the sealing plate all slide at the top of the bottom mold, and the length of the bottom mold is greater than the lengths of the first lower mold and the second lower mold.

[0012] Preferably, the parts of the first lower mold and the second lower mold that contact the bottom mold are arranged with an arc surface structure, and the height of the first lower mold and the second lower mold is greater than the height of the bottom mold.

[0013] Preferably, the ejection mechanism includes protrusions and second hydraulic rods. Several protrusions are equidistantly and annularly engaged on the bottom mold. A fixed plate is fixedly connected to the operating table. Several second hydraulic rods are fixedly installed on the fixed plate. The telescopic ends of the second hydraulic rods are fixedly connected to protrusions. The bottom mold is provided with slots.

[0014] Preferably, a protrusion is engaged in the slot portion, and the telescopic end of the second hydraulic rod is slidably connected to the bottom mold.

[0015] The beneficial effects of this utility model are as follows: When casting the wheel hub, the operator can activate the control switch of the first hydraulic rod.

When activated, their telescopic ends can drive the first lower mold and the second lower mold to slide towards each other. When the first lower mold and the second lower mold are engaged together, the first lower mold and the second lower mold can be engaged with the fixing mechanism, thereby sealing the lower mold of the mold. Then, the upper mold of the mold is engaged inside the lower mold of the mold, and molten metal liquid can be poured into the mold. While waiting for the mold to cool and form, water can be discharged into the cooling tanks provided in the first lower mold and the second lower mold through the liquid inlet pipe. The setting of the cooling tank can accelerate the forming speed of the wheel hub. The side walls of the first lower mold and the second lower mold are also equipped with drain pipes. Through the drain pipes, the water in the cooling tank can be discharged, which facilitates water circulation and thus helps to improve the casting effect of the wheel hub.

The drain pipe 203 and the inlet pipe 206 are connected to the cooling tank 208. Water is drained into the interior of the first lower mold 204 and the second lower mold 205 through the inlet pipe 206, and finally the water can be drained out through the drain pipe 203.

[0028] As a technical optimization of this utility model, the fixed base 201 is located at the top of the operating table 1, and the two first hydraulic rods 202 are symmetrically arranged on the side wall of the fixed base 201. The fixed base 201 supports the first hydraulic rods 202, so that the first lower mold 204 and the second lower mold 205 can be driven to slide through the first hydraulic rods 202.

[0029] As a technical optimization of this utility model, the first lower mold 204 and the second lower mold 205 are engaged and connected, and the sealing plate 207 is set with an arc surface structure. The sealing plate 207 seals the cooling groove 208, so that water can be retained inside the first lower mold 204 and the second lower mold 205.

[0030] As a technical optimization of this utility model, the fixing mechanism 4 includes a support rod 402 and a bottom mold 403. Two sets of support rods 402 are installed on the operating table 1. The bottom mold 403 is engaged with the support rod 402. A support seat 401 is fixedly connected to the support rod 402. The support seat 401 positions the support rod 402, which facilitates fixing the bottom mold 403 to the top of the operating table 1.

[0031] As a technical optimization of this utility model, the support base 401 is fixedly connected to the operating table 1, and the two sets of support bases 401 are symmetrically arranged. The support base 401 is installed on the operating table 1 by fixing bolts, which can position the mold.

[0032] As a technical optimization of this utility model, the first lower mold 204, the second lower mold 205 and the sealing plate 207 all slide at the top of the bottom mold 403. The length of the bottom mold 403 is greater than the length of the first lower mold 204 and the second lower mold 205. When the first lower mold 204 and the second lower mold 205 slide along the top of the bottom mold 403, it is convenient to disassemble the cast wheel hub.

[0033] As a technical optimization of this utility model, the parts of the first lower mold 204 and the second lower mold 205 that contact the bottom mold 403 are arranged with an arc surface structure. The height of the first lower mold 204 and the second lower mold 205 is greater than the height of the bottom mold 403. When the first lower mold 204 and the second lower mold 205 are engaged with the bottom mold 403, it is convenient to position the upper mold.

[0034] As a technical optimization of this utility model, the ejection mechanism 3 includes a protrusion 302 and a second hydraulic rod 303. A plurality of protrusions 302 are equidistantly engaged in a ring on the bottom mold 403. A fixing plate 301 is fixedly connected to the operating table 1. A plurality of second hydraulic rods 303 are fixedly installed on the fixing plate 301. The telescopic end of the second hydraulic rod 303 is fixedly connected to the protrusion 302. The bottom mold 403 is provided with a slot 304. The second hydraulic rods 303 drive the protrusions 302 to move upward, so that the protrusions 302 can eject the cast wheel hub.

[0035] As a technical optimization of this utility model, a protrusion 302 is engaged and installed in the slot 304 part, and the telescopic end of the second hydraulic rod 303 is slidably connected to the bottom mold 403. When the protrusion 302 pushes the wheel hub out of the first lower mold 204 and the second lower mold 205, it is convenient for the operator to take out the wheel hub.

[0036] In use, when casting the wheel hub, the operator can activate the control switch of the first hydraulic rod 202. Two sets of first hydraulic rods 202 are respectively installed on the side walls of two fixed seats 201. When activated, their telescopic ends drive the first lower mold 204 and the second lower mold 205 to slide towards each other. When the first lower mold 204 and the second lower mold 205 are engaged, they can engage with the bottom mold 403, thus sealing the lower mold. Then, the upper mold is engaged inside the lower mold, and molten metal can be poured into the mold. While waiting for the mold to cool and solidify, water can be drained through the inlet pipe 206 into the cooling tanks 208 provided in the first lower mold 204 and the second lower mold 205. The cooling tanks 208 accelerate the wheel hub forming speed. Drain pipes 203 are also installed on the side walls of the first lower mold 204 and the second lower mold 205, allowing water to flow through... Water in the cooling tank 208 can be drained through the drain pipe 203, facilitating water circulation and improving the casting effect of the wheel hub. After the wheel hub is formed, the first hydraulic rod 202 is activated, and its telescopic end drives the first lower mold 204 and the second lower mold 205 to slide, thereby separating the first lower mold 204 from the second lower mold 205. At this time, the control switch of the second hydraulic rod 303 is activated, allowing its telescopic end to slide within the first lower mold 204 and the second lower mold 205. The telescopic end of the second hydraulic rod 303 is fixedly connected to a protrusion 302. The protrusion 302 slides out of the slot 304 with the telescopic end of the second hydraulic rod 303, thereby causing the protrusion 302 to abut against the formed wheel hub. Several protrusions 302 are arranged in a ring at equal intervals. After the protrusions 302 push the wheel hub out of the first lower mold 204 and the second lower mold 205, it is easy for the operator to use tools to remove the formed wheel hub, thereby improving the material removal effect of the wheel hub.
