AI Technical Summary
In existing die-casting machines, the cooling water inlet and outlet are located at the bottom, which causes the temperature of the cooling water to rise after exchanging heat with the inner mold, reducing the heat exchange capacity of the cooling water at the bottom and affecting work efficiency.
An inverted funnel-shaped cooling shell is fitted on the outside of the inner mold, and multiple water inlets are set on the cooling shell. Cooling water first contacts the upper part of the inner mold and then enters. Combined with a semiconductor cooling chip and a temperature sensor, uniform heat exchange and temperature control are achieved.
The cooling capacity of the lower part of the cooling shell is improved, ensuring uniform heat exchange and increasing the molding speed and working efficiency of die castings.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware accessories processing, and in particular to a die-casting machine for hardware accessories production. Background Technology
[0002] Die casting machines are machines used for pressure casting, including both hot and cold chamber types, and are further divided into vertical and horizontal types. Under pressure, the die casting machine injects molten metal into a mold to cool and solidify. After the mold is opened, a solid metal casting can be obtained. It was initially used for die casting lead type. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and home appliances, die casting technology has developed extremely rapidly.
[0003] According to application number "CN202020416443.X", the die-casting machine for producing hardware accessories achieves rapid molding by setting up water channels, sealing rings, and water inlet pipes. Liquid metal is injected into the inner barrel mold and then basically formed by the extrusion of the die-casting plate. At this time, the entire component has low structural strength due to high temperature. Cooling water is injected into the water channels through the water inlet pipe. At the same time, the water channels are ring-shaped and wrap around the bottom of the inner barrel, so the parts cool down quickly. At the same time, a drain pipe is set up to ensure that the cooling water temperature is relatively low, which greatly improves the molding speed of the parts and improves the work efficiency.
[0004] In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been well resolved: the inlet and outlet of the cooling water are both located at the bottom, which means that when the cooling water enters, it will first exchange heat with the inner mold, causing the temperature of the cooling water flowing to the bottom of the cooling chamber to rise, resulting in a decrease in the heat exchange capacity of the cooling water at the bottom, thereby reducing the working efficiency. Utility Model Content
[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.
[0006] A die-casting machine for producing hardware accessories, including a base;
[0007] The upper part of the base is provided with an outer shell, the inside of which is provided with an inner mold, and a cooling shell is fitted on the outside of the inner mold in the middle of the outer shell;
[0008] The cooling shell has an inverted funnel-shaped structure. Multiple water inlets are arranged in a circular array at the top of the cooling shell. A water inlet pipe is provided on one side of the upper end of the cooling shell, and the water inlet pipe is connected to the water inlets. A water outlet pipe is provided on the other side of the lower end of the cooling shell.
[0009] As a further embodiment of this utility model: a hydraulic cylinder is provided in the middle of the lower end of the base, the telescopic end of the hydraulic cylinder passes upward through the base and is located in the inner bottom of the inner mold, and a push plate is installed thereon, with the push plate and the inner mold slidingly engaging with each other.
[0010] As a further embodiment of this utility model: the middle part of the bottom of the outer shell and the middle part of the base are respectively provided with clearance grooves for the movement of the extension and retraction end of the hydraulic cylinder.
[0011] As a further embodiment of this utility model: the bottom of the base is provided with multiple support columns on the outside of the hydraulic cylinder.
[0012] As a further embodiment of this utility model: a plurality of semiconductor cooling chips are provided on the outer side of the cooling shell, with the cold end of the semiconductor cooling chip located inside the cooling shell and the hot end of the semiconductor cooling chip located on the outer side of the cooling shell.
[0013] As a further embodiment of this utility model: a temperature sensor is provided on the outer side of the base, and the monitoring end of the temperature sensor is located inside the cooling shell.
[0014] Compared with the prior art, the beneficial effects of this utility model are: by providing a cooling shell with an inverted funnel-shaped structure on the outside of the inner mold, and providing multiple water inlets at the upper end of the cooling shell, when the water inlet pipe enters the cooling shell through the water inlet, the cooling water will first come into contact with the inner mold for heat exchange. At the same time, the space in the lower part of the cooling shell is larger than that in the upper part, which improves the cooling capacity of the lower part of the cooling shell and achieves a uniform heat exchange effect.
