[0002] Aluminum alloy die-casting products are mainly used in electronics, automobiles, motors, home appliances and some communication industries. Some high-quality aluminum alloy products with high performance, high precision and high toughness are also used in industries with relatively high requirements such as large aircraft and ships. , the main purpose of the die-casting machine is to process some parts of the equipment; the existing aluminum alloy die-casting machine has certain disadvantages when using the melt spray gun. The speed at which the plunger pushes the molten material is not stable enough, resulting in It is not uniform enough, and at the same time, the gears are easy to back out and be damaged. When the piston rod moves horizontally and linearly, it is prone to longitudinal vibration, which wastes power and affects the transmission effect. It brings certain adverse effects during use. For this reason, we propose Melting spray gun for aluminum alloy die-casting machine

Embodiment Construction
[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0019] Such as Figure 1-3 As shown, a melt injection spray gun for aluminum alloy die-casting machine includes a spray gun main body 1, a transmission box 2 is welded on the outside of one end of the spray gun main body 1, and a nozzle 3 is threaded on the outside of the other end of the spray gun main body 1, and the inner side of the spray gun main body 1 There is a molten metal channel 4 on the surface, and a regulating valve 5 is movable installed inside the molten metal channel 4. A piston 6 is movably installed at the inner middle position of the spray gun body 1, and a piston rod 7 is welded on the outside of one end of the piston 6. The outer sides of the upper and lower ends of 7 are riveted with oil shock absorbers 8, and oil passages 9...

The invention discloses an injection melting spray gun for an aluminum alloy die casting machine. The injection melting spray gun comprises a spray gun body. A transmission box is welded to the outerside of one end of the spray gun body. A spray nozzle is in threaded connection with the outer side of the other end of the spray gun body. A metal melting material channel is arranged on the inner surface of the spray gun body. According to the injection melting spray gun for the aluminum alloy die casting machine, a worm, a worm wheel and an oil pressure damper are arranged. Compared with transmission of an ordinary gear, the transmission ratio of the worm structure is high, the structure is compact, and stability is high; stability of plunger thrust velocity can be improved, and uniformityof melting material injection can be ensured; the worm structure has the self-locking performance, and gear receding does not occur; and through movement of hydraulic oil, kinetic energy is convertedinto heat energy to be consumed, and therefore the aim of piston rod damping is achieved, a piston can move linearly, the transmission effect is improved, application in different working stations isachieved, and better application prospect can be brought.
