Description

Technical Field

[0001] This utility model relates to the field of die-casting equipment technology, and more specifically, to a material injection mechanism with a liquid cooling structure. Background Technology

[0002] Currently, most die-casting machines on the market are equipped with a furnace, a material pot, and an injection drive device. The material pot is installed inside the furnace, and the injection drive device is mounted directly above the material pot via an injection support frame. The injection drive device can inject the material from the material pot into the mold cavity of the die-casting machine. For example, the injection mechanism of a high-speed die-casting machine with patent application number 202222488704.0 has its material pot inlet located at the bottom of the material pot body, and the material pot uses a ball valve to control the opening and closing of the inlet. This structure is novel, has a good injection effect, and can extract material located at the lower end of the furnace, reducing the frequency of material feeding and making it convenient to use. However, in practical applications, in order to push the die-casting machine mold frame so that the mold on the mold frame can separate from the nozzle of the material pot, it is often necessary to add push-die cylinders at both ends of the injection support frame. The output rod of the push-die cylinder can be connected to the mold frame to push the mold frame away from the nozzle of the material pot. However, during operation, the heat generated by the furnace is transferred through the material pot to the left and right ends of the injection support frame, and then to the ejector cylinder. This will affect the operation and service life of the ejector cylinder. To solve this problem, the common practice is to use a cylinder with internal cooling function, but the purchase cost of such cylinders is high. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide an injection mechanism with a liquid cooling structure, which can avoid the impact of high temperature on the operation of the ejector cylinder, improve the service life of the ejector cylinder, and eliminate the need for a special cylinder with internal cooling function, only a regular cylinder is needed, thereby reducing the manufacturing cost of die casting equipment.

[0004] To achieve the above objectives, this utility model provides an injection mechanism with a liquid-cooled cooling structure, including a furnace, a material pot, and an injection drive device. The injection drive device is mounted above the furnace via a tripod. The material pot is installed inside the furnace, and its upper end is fixedly connected to the bottom middle part of the tripod. The pressing part of the injection drive device can move up and down within the material cavity of the material pot. At least one liquid-cooled flow channel and a push-die cylinder for pushing the die frame of the die-casting machine are provided at both ends of the tripod. The liquid-cooled flow channel is located between the push-die cylinder and the material pot, and extends along the thickness direction of the tripod and runs through the tripod from front to back.

[0005] Preferably, the left and right ends of the tripod are provided with hollowed-out grooves extending in the left and right direction of the tripod, so that the left and right ends of the tripod form a U-shaped end structure. The push-molding cylinder is installed between the front plate and the rear plate of the U-shaped end structure and passes through the hollowed-out groove laterally. The liquid cooling channel is located between the inner end of the hollowed-out groove and the material pot.

[0006] Preferably, the furnace is configured as an electrically heated furnace.

[0007] Preferably, the injection drive device includes an injection drive cylinder and a pressing hammer. The injection drive cylinder is installed at the top center of the tripod, and the pressing hammer is connected to the output rod of the injection drive cylinder. The injection drive cylinder can drive the pressing hammer to move up and down inside the material container.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model has liquid cooling channels at both ends of the tripod, located between the material pot and the die-casting cylinder. These liquid cooling channels are located on the heat transmission path, which can reduce heat transfer, prevent high temperature from affecting the operation of the die-casting cylinder, improve the service life of the die-casting cylinder, and eliminate the need for special cylinders with internal cooling function. Ordinary cylinders can be used, thus reducing the manufacturing cost of die-casting equipment.

[0011] 2. The present invention also provides hollowed-out grooves extending in the left and right directions of the tripod at the ends of the left and right ends of the tripod. The hollowed-out grooves can reduce the heat transfer area, so that the heat must pass through the liquid cooling channel, thereby better reducing the heat transfer to the push mold cylinder.

The material injection drive cylinder 31 is installed at the top center of the tripod 4. The pressing hammer 32 is connected to the output rod of the material injection drive cylinder 31. The material injection drive cylinder 31 can drive the pressing hammer 32 to move up and down in the material cavity of the material pot 2.

[0021] It should be noted that this embodiment does not involve structural improvements to the material container 2. It can be the material container from the injection mechanism of a high-speed die-casting machine as described in the applicant's earlier patent application (patent number 202222488704.0), or any commonly available die-casting machine material container. The material container 2 can extract material from the furnace 1 and inject it into the die-casting machine's mold.

The inlet and outlet of the liquid cooling channel 5 can be connected to a water source or other coolant through water pipes. Water or other coolant can flow through the liquid cooling channel 5.

[0023] In this embodiment, the liquid cooling channel is located on the heat transmission path, which can reduce heat transfer, avoid high temperature affecting the operation of the die-casting cylinder, improve the service life of the die-casting cylinder, and eliminate the need for a special cylinder with internal cooling function; only an ordinary cylinder is needed, thus reducing the manufacturing cost of the die-casting equipment.

[0024] As a further improvement of this embodiment, the ends of both the left and right ends of the tripod 4 can be provided with hollowed-out grooves 7 extending in the left and right directions of the tripod 4, so that the ends of the left and right ends of the tripod 4 form a U-shaped end structure. The push-molding cylinder 6 is installed between the front plate 8 and the rear plate 9 of the U-shaped end structure and passes through the hollowed-out groove 7 laterally. The liquid cooling channel 5 is located between the inner end of the hollowed-out groove 7 and the material pot 2.

[0025] In this embodiment, the hollowed-out groove can reduce the heat transfer area, so that heat must pass through the liquid cooling channel, thus better reducing the heat transfer to the push mold cylinder.
