With the progress of scientific technology and industrial production, especially with the development of industries such as automobiles, motorcycles, household appliances and the like, the die casting technology has been developed extremely rapidly from various aspects.

The classification method of the die casting machine is various, and the die casting machine is divided into a general die casting machine and a special die casting machine according to the application range; according to the size of the mold locking force, the mold is divided into a small machine (less than or equal to 4000 kN), a medium machine (4000 kN-10000 kN) and a large machine (more than or equal to 10000 kN); generally, they are classified mainly according to the machine structure and the position of the shot chamber (hereinafter referred to as a pressure chamber) and their operating conditions.

The die casting machine is divided into a hot-pressing chamber die casting machine and a cold-pressing chamber die casting machine. The cold pressing chamber die casting machine is divided into a horizontal type and a vertical type according to the structure and the arrangement mode of the pressing chamber. The die closing mechanism of the hot pressing chamber die casting machine is the same as that of the cold pressing chamber die casting machine, and the difference is that the injection mechanism and the pouring mechanism are different. The chamber of the hot chamber die casting machine is tightly connected with the smelting furnace into a whole, and the chamber of the cold chamber die casting machine is separated from the smelting furnace.

The front end of the injection rod is connected with the injection head, the injection head is used for injecting high-temperature molten metal, the injection head is in direct contact with the high-temperature molten metal, for example, the temperature of molten metal is about 700 ℃, so the temperature of the injection head is very high, the temperature of the injection head is conducted to the injection rod, the temperature of the injection rod is increased, and the temperature of the injection rod needs to be reduced. Hydraulic oil is used for all hydraulic parts of the die casting machine, and the hydraulic oil is a hydraulic medium used by a hydraulic system utilizing hydraulic pressure energy and plays roles of energy transfer, wear resistance, system lubrication, corrosion resistance, rust resistance, cooling and the like in the hydraulic system. Therefore, a large part of friction heat is brought out by the hydraulic oil, so that the temperature of the hydraulic oil is increased, the hydraulic effect is not ideal when the temperature of the hydraulic oil reaches 60 ℃, and the hydraulic oil needs to be cooled.

Chinese utility model patent with patent application No. CN201720737696.5 discloses a cooling structure is united to injection rod hydraulic oil of die casting machine, including the injection cylinder with set up the injection rod at the injection piston rod front end of injection cylinder, the injection head is connected to the injection rod front end, the injection rod is both ends open-ended hollow tube, an open end is connected with the radiator head that is used for connecting the injection head, the radiating block of radiator head stretches into in the hollow tube, it has a plurality of through-holes to open on the radiating block, the hollow tube lateral wall is opened has a pair of elongated slot of arranging along hollow tube length direction, be equipped with in the elongated slot and cut apart into the hollow tube cavity about the baffle of two parts, the top cavity connection pierces through the intake pipe of hollow tube, the lower side cavity connection pierces through the delivery pipe of baffle and hollow tube, the delivery pipe of intake pipe connection set up the radiator coil's in the oil tank delivery port, coil pipe heat dissipation water inlet junction. It is through the cooling water that comes out from the cooling coil pipe again from the takeover of intaking enter into the hollow tube in to the radiating head heat dissipation, intake from hollow tube upper portion cavity toward the radiating head circulation and flow to the lower part cavity from the radiating head through-hole and discharge from the takeover of water play again, realize the heat dissipation. However, since the injection rod needs to be externally connected with a water pipe, water often splashes out of the joint of the injection rod and the water pipe, and in order to avoid the danger that cooling water is leaked and splashed to enter a furnace filled with molten aluminum liquid by mistake to cause aluminum liquid splashing, a protective device needs to be installed around the injection rod.

The known guards are usually a sheet metal plate mounted laterally to the injection plunger, up to the top of the latter, and have the advantage of a simple structure. However, since the mounting direction of the injection rod is usually the up-down direction, i.e., the injection rod needs to be removed upward and installed downward, when the injection rod needs to be replaced, the entire sheet metal plate needs to be removed first, and after the injection rod is replaced, the sheet metal plate is mounted in place to achieve the protection effect. In the process, the steps are multiple, the time is long, the efficiency is low, the labor intensity of operators is enhanced, and meanwhile the working efficiency of the die-casting machine is influenced.
