Description

Technical Field

[0001] The invention discloses a casting mould for automobile parts which is convenient for ejecting finished products and belongs to the technical field of casting moulds. Background Art

[0002] Casting molds are widely used in the manufacturing industry, and many prefabricated products can be formed in one go. Casting molds usually include inner molds and outer molds, which can form a closed space to inject casting materials. After being fixed, the mold is opened to form a prefabricated product. During the mold forming process, it is necessary to ensure its appropriate internal space, so a positioning plate is clamped between the inner mold and the outer mold for positioning.

[0003] The casting of automobile parts is basically mass-produced, but the existing casting molds often have bubbles in the corners during the molding process, resulting in unqualified parts that can only be scrapped, which is a great waste of raw materials and workers' time. For this reason, we propose an automobile parts casting mold that is easy to eject the finished product. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automotive parts casting mold that is easy to eject finished products, so as to solve the problem that in the existing casting molds, bubbles in the corners often occur during the molding process, resulting in unqualified parts that can only be scrapped, which greatly wastes raw materials and workers' time.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a casting mold for automobile parts that is convenient for ejecting finished products, and its structure includes a base, the bottom of the base is fixedly connected with a support foot and a mounting shell, the top of the base is fixedly connected with a support rod, the side of the support rod is fixedly connected with a connecting rod, the other end of the connecting rod is fixedly connected with a limiting ring, the inner wall of the limiting ring is installed with a buffer spring, the other end of the buffer spring is fixedly connected with a cooling groove, the top of the cooling groove is installed with a mold cover, the outer side wall of the mold cover is fixedly connected with a fixing block, the top of the fixing block is installed with a screw, and the mold cover is fixedly connected with a fixing block. An injection port is provided on the top, a coolant outlet is provided on the side of the cooling groove, a coolant inlet is provided on the other side of the cooling groove, a receiving block is provided at the bottom of the coolant inlet, a motor is fixedly installed on the inner bottom surface of the mounting shell, a rotating disk is fixedly installed on the output end of the motor, a connecting rod is movably connected to the side of the rotating disk, a push-pull rod is movably connected to the other end of the connecting rod, a torsion ball is fixedly connected to the top of the push-pull rod, a movable ball is movably connected between the cooling groove and the base, a mold core is installed inside the cooling groove, and a hanging ear is provided on the side of the cooling groove, and the mold core is fixed by the hanging ear.

[0006] Furthermore, a groove is provided on the bottom surface of the receiving block, and the groove and the torsion ball are matched with each other with a clearance fit. The cooling groove is movably connected to the receiving block through the torsion ball. A through hole matching the cooling groove is provided on the top surface of the base, and the casting liquid is injected through the injection port set on the top of the mold cover.

[0007] Furthermore, the rotating disk and the connecting rod are eccentrically connected, and the connection point between the rotating disk and the connecting rod is located on the side of the rotating disk. The rotating disk is movably connected through the connecting rod and the push-pull rod. The push-pull rod completely penetrates the base. The rotating disk drives the push-pull rod to move up and down through the connecting rod, and the push-pull rod drives the cooling groove to swing left and right around the movable ball through the supporting block.

[0008] Furthermore, the movable ball is located between the cooling groove and the base, the bottom end of the cooling groove is conical, the bottom end of the cooling groove is provided with a groove that fits with the movable ball, the top surface of the base is provided with a fitting groove that fits with the movable ball, the cooling groove is movably connected to the base through the movable ball, and the mold is cooled through the cooling groove.

[0009] Furthermore, the sides of the mold cover and the cooling groove are fixedly connected with fixing blocks, the top surface of the fixing block is provided with a penetrating threaded groove, the screws and the threaded groove fit together, the mold cover and the cooling groove are fixedly connected by screws, and the screws and nuts play a fixing role.

[0010] Furthermore, the injection port completely penetrates the mold cover, and the bottom end of the injection port is located directly above the cooling groove. By connecting a water pump to the coolant inlet and the coolant outlet, the coolant can flow inside the cooling groove, ensuring that the coolant continuously wraps the mold core.

[0011] Furthermore, the hanging ears are fixedly installed on the side of the mold core, and the hanging ears are fixedly connected between the mold cover and the cooling groove by screws. The mold core can be lifted by the hanging ears for easy transportation.

[0012] Furthermore, the two ends of the buffer spring are respectively fixedly connected to the mold cover and the limit ring, and the limit ring is movably connected to the mold cover through the buffer spring. The buffer spring is evenly distributed on the side wall of the mold cover. When the motor is working, the cooling groove swings left and right. Under the action of the buffer spring, the swing amplitude of the cooling groove is limited to buffer the swinging motion.

[0013] Beneficial Effects

[0014] First, the rotating disk is driven by the motor to rotate, and the rotating disk drives the push-pull rod to move up and down through the connecting rod. The push-pull rod drives the cooling trough to swing left and right around the movable ball through the receiving block, so that the molten metal poured from the injection port is evenly distributed inside the mold core, avoiding bubbles in the corners and waste caused by uneven pouring, improving the product yield, reducing the waste of raw materials, and avoiding wasted working time as much as possible;

[0015] Second, the mold core is fixedly installed between the mold cover and the cooling trough through the hanging ears. When pouring, the pouring liquid is injected through the injection port set on the top of the mold cover and flows into the mold core for molding. After molding, the mold core can be taken out by removing the screws, and a new mold core can be replaced to continue pouring. The finished product can be taken out directly by inverting the taken out mold core, which is simpler and more convenient.

[0016] Third, the limit ring is supported by the support rod, and a buffer spring is arranged between the limit ring and the cooling groove. When the motor is working, the cooling groove swings left and right. Under the action of the buffer spring, the swing amplitude of the cooling groove is limited, and the swing action is buffered to avoid the internal pouring liquid splashing out due to the large amplitude, causing danger, thereby improving safety;

[0017] Fourth, by connecting a water pump to the coolant inlet and the coolant outlet, the coolant can flow inside the cooling tank, ensuring that the coolant continuously wraps the mold core, thereby achieving the effect of increasing the cooling rate and increasing efficiency.
