Embodiment 1

[0047] see Figure 1-3 , a feeding system for a horizontal cold chamber die-casting machine, which includes a barrel 10, and the barrel 10 is provided with a plunger 2 for hydraulically injecting molten metal in the barrel 10 into the mold cavity 6, so The tail end of the plunger 2 is connected to the driving mechanism, and the side wall of the barrel 10 is provided with a molten metal channel 3 for injecting molten metal into the barrel 10, and the molten metal channel 3 is communicated through a pipeline 4 into the metal smelting chamber 5; the plunger 2 includes a first sealing portion for sealing during injection and a second sealing portion for preventing the molten metal in the cylinder 10 from leaking backward Two sealing parts, the cavity between the first sealing part, the inner wall of the barrel 10 and the discharge port 105 of the barrel 10 forms a pressure chamber 100 for storing the molten metal liquid to be shot, so The cavity between the first sealing part, th...

Embodiment 2

[0068] This embodiment provides a feeding system for a horizontal cold chamber die-casting machine, which is a further improvement on the basis of Embodiment 1. In this embodiment, in order to facilitate the installation of the double-sealed plunger of the present invention to the barrel 10, and to ensure that the plunger has a relatively stable operating state in the barrel 10, on the basis of the first embodiment above, the second plunger head 21' and the plunger head 21 are relatively The structure of the center point in the length direction of the plunger rod 20 is symmetrical, that is, the structure of the second plunger head 21' is consistent with the structure of the plunger head 21. This arrangement is beneficial to ensure that the plunger is in the When the barrel 10 is in operation, the frictional force between the sealing parts at both ends and the inner wall of the barrel is basically equal, and can reciprocate relatively smoothly along the axial direction, thereby ...

Embodiment 3

[0071] This embodiment provides a feeding system for a horizontal cold chamber die-casting machine, which is a modification based on Embodiment 1 or 2. In this embodiment, see Figure 7 , Figure 8 (For the convenience of showing the specific structure of the fluid heating device, the structure of the molten metal channel 3 is omitted in these two figures), the outer side of the straight part 108 and the gooseneck 109 is provided with a heating device 102, the The heating device 102 is a thermal fluid heater, and the outer side of the heating device 102 is provided with a heat insulating sleeve 110 for heat preservation. The heating device 102 can properly heat the molten metal in the barrel 10 to keep it at the injection temperature, thereby improving the casting quality and production efficiency. On the one hand, the heat insulating sleeve 110 can prevent the inner wall of the high-temperature barrel and the heating device from heat exchange with the outside air to reduce t...

Abstract

The invention discloses a feeding system of a horizontal cold chamber die casting machine. The feeding system comprises a charging barrel, wherein a plunger is arranged in the charging barrel; the tail end of the plunger is connected with a driving mechanism; the side wall of the charging barrel is provided with a molten metal passage; the molten metal passage is communicated into a metal smelting chamber through a pipeline; the plunger comprises a first sealing part and a second sealing part which are axially spaced from each other; a cavity among the first sealing part, the inner wall of the charging barrel and the discharge port of the charging barrel form a pressure chamber for storing molten metal to be injected; a cavity among the first sealing part, the second sealing part and the inner wall of the charging barrel form a pressure-free chamber; the molten metal passage is suitable for communicating the pressure chamber when the plunger is positioned at an initial position and is suitable for communicating the pressure-free chamber when the plunger is used for performing injection or reciprocating motion. According to the feeding system of the horizontal cold chamber die casting machine, the quantity of the molten metal injected into the charging barrel is convenient to control, the injection time is shortened, and the die casting efficiency is improved.

Description

technical field [0001] The invention relates to a feeding system for a horizontal cold chamber die-casting machine, which belongs to the technical field of die-casting equipment feeding. Background technique [0002] Die casting is to inject a molten alloy into the barrel, and then inject a certain amount of molten alloy into the cavity through the plunger arranged in the barrel, and form a casting after cooling and molding. [0003] The barrel in traditional die-casting equipment can only be filled with a certain amount of molten metal according to the size of the casting. After the injection is completed, the plunger is reset to the initial position, and a certain amount of molten metal is added to the barrel again for the next die-casting. Due to the high temperature of the molten metal, it is very dangerous to the operator. Generally, tools such as a spoon are used to add the molten metal into the pressure chamber of the barrel, and the spoon is fed from the metal meltin...
