Description

Technical Field

[0001] The utility model relates to the technical field of die-casting equipment, in particular to die-casting equipment for hardware products. Background Art

[0002] Die casting is a precision casting method that uses high pressure to force molten metal into a complex-shaped metal mold. Its characteristic is that high pressure is applied to the molten metal in the mold cavity. The mold is usually made of higher-strength alloys. This process is somewhat similar to injection molding. Therefore, most die-cast castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, lead-tin alloys and their alloys.

[0003] In the prior art, application number CN202021353940.6 provides an aluminum alloy die-casting device, including a booster cylinder, a feed pipe is provided at the top of one side of the booster cylinder, and a push rod motor is fixedly connected to the top of the outer wall of one side of the booster cylinder, a piston rod is fixedly connected to one side of the top of the push rod motor, and the bottom end of the piston rod is inserted into the inside of the booster cylinder, a piston is fixedly connected to the bottom of the piston rod, and the outer diameter of the piston is adapted to the inner diameter of the booster cylinder, and an arc bucket is welded to the bottom of the booster cylinder, and the inner diameter of the bottom of the arc bucket is smaller than the inner diameter of the top of the booster cylinder. The utility model drives the piston downward through the push rod motor to inject the molten aluminum alloy inside the booster cylinder into the mold, the inner diameter of the arc bucket is gradually tightened from top to bottom, and the speed of the piston moving downward remains unchanged, so the pressure on the aluminum alloy in the process of leaving the arc bucket gradually increases, and the aluminum alloy is pressurized and pre-treated before entering the mold to improve the quality of the die-casting product.

[0004] In the above patent, the purpose of further pressurization is achieved mainly by connecting the upper discharge port on the die-casting mold and pressing the molten aluminum alloy into the die-casting mold through the push rod motor. However, this pressurization method, since the feed pipe and the piston are in a separate state, this will cause part of the molten aluminum alloy remaining in the feed pipe to flow to the top of the piston when the piston is squeezed downward, making it impossible for this part of the molten aluminum alloy to be squeezed downward again and will remain at the upper end of the piston, causing serious material waste.

[0024] The utility model provides a die-casting device for hardware products. A die-casting device for hardware products includes a booster device 1, a booster 11 is provided in the booster device 1, a housing 111 is installed in the booster 11, a motor 116 is installed in the housing 111, a flow port 113 is provided next to the motor 116, a booster ball 114 is connected to the flow port 113, a penetration ball 115 is installed next to the booster ball 114, an electric push rod 112 is provided next to the penetration ball 115, one side of the electric push rod 112 is connected to one side of the booster ball 114, a controller 4 is embedded in the booster device 1, a melting tank 3 is connected to the controller 4, a mold 2 is installed next to the controller 4, the lower end of the booster device 1 is matched with the upper end of the mold 2, the lower end of the mold 2 is connected to the upper end of the melting tank 3, and a plurality of hydraulic telescopic Rod 13, a pressing plate 14 is installed next to the hydraulic telescopic rod 13, a boosting port 15 is opened in the pressing plate 14, a telescope 12 is installed next to the boosting port 15, the outer side of the telescope 12 cooperates with the outer side of the hydraulic telescopic rod 13, a large sleeve 123 is installed next to the boosting port 15, a connecting key 124 is connected to the large sleeve 123, a fastening thread 121 is opened next to the connecting key 124, a small sleeve 122 is connected to the fastening thread 121, the inner side of the boosting port 15 is connected to the inner side of the large sleeve 123, the lower end of the small sleeve 122 is connected to the outer side of the connecting key 124, the outer side of the penetrating ball 115 cooperates with the outer side of the boosting ball 114, the outer side of the large sleeve 123 is engaged with the upper end of the supercharger 11, and one side of the motor 116 is embedded with one side of the penetrating ball 115.

[0025] The model used by the electric linear actuator 112 is XDHA24-500. With its advantages such as silent gears, stable base, and low-resistance metal casing, the electric linear actuator 112 can operate more stably and for a long time in the die-casting equipment of hardware products.

[0026] The model of the motor 116 is 5IK40W (speed ratio 20-36) ordinary type. With its advantages of high cost performance, stable speed, sensitive response, durability, etc., the motor 116 can rotate the penetrating ball 115 more stably.

[0027] The overall size of the penetrating ball 115 is consistent with the size of the pressurizing port 15, so that the penetrating ball 115 can directly block the flow of the pressurizing port 15 when it is closed.

[0028] The working principle of the present invention is explained below: the various mechanical structures inside the die-casting equipment for hardware products are all fixed by threads unless otherwise specified. In order to more intuitively observe the professional and technical features in the figure, the bolted connections are appropriately hidden. Before using the die-casting equipment for hardware products, the user needs to transport the molten hardware materials to be used into the melting tank 3. The melting tank 3 can transport the internal molten hardware materials into the mold 2. Since the die-casting technology in the die-casting equipment for hardware products is a mature existing technology, the present invention does not elaborate on it. The user can electrically control the entire die-casting equipment for hardware products through the controller 4. When the die-casting equipment for hardware products needs to increase the pressure in the mold, the user first allows the hydraulic telescopic rod 13 to move the entire pressing plate 14 downward to the top of the mold 2. Since a through hole is opened above the mold 2, the through hole on the mold 2 is inserted into the pressurizing port 15, and the pressing plate 14 is attached to the mold 2. The surface of the mold 2 can be closed. The hydraulic telescopic rod 13 will cause the small sleeve 122 to shrink downward in the large sleeve 123 during the extension and retraction process. At this time, the user will convey the molten hardware material downward through the uppermost end of the booster device 1. The molten hardware material will flow downward along the telescopic device 12, and then flow into the mold 2 through the flow port of the penetrating ball 115 and along the flow port 113. The rotation of the motor 116 can cause the penetrating ball 115 to rotate, so as to control the flow rate of the molten hardware material. The principle is similar to that of the ball valve. Then the user uses the electric push rod 112 to push the booster ball 114 downward. The booster ball 114 pushed downward will directly squeeze the molten hardware material under the booster port 15, so as to play the role of boosting the internal pressure of the mold 2. Since the molten hardware material is always in a state of circulation inside the die-casting equipment of the hardware products, it will not cause waste of raw materials, thereby improving practicality.

[0029] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the utility model is limited by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
