Technical Field

[0001] The utility model relates to the technical field of electrothermal processing, in particular to an electrothermal processing tool for lost casting models. Background Art

[0002] Lost casting is a new casting method. Its main process is to bond foam models with similar size and shape to the casting into a model cluster, brush refractory paint and dry it, and then bury it in dry quartz sand for vibration molding. When pouring under negative pressure, the model will gasify, liquid metal will occupy the position of the model, and after solidification and cooling, it will form a casting.

[0003] Lost foam casting has many advantages, such as high casting precision, flexible design, clean production, etc. At the same time, highly complex castings can be cast by combining foam plastic molds. In addition, lost foam casting is also a clean production method because there is no chemical binder in the molding sand and the recovery rate of old sand is also high.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] The invention discloses an electrothermal processing tool for a lost casting model, comprising a shell 1. A cutting device 2 for cutting the model and a hot melt device 3 for bonding the model are respectively arranged at the top and bottom ends of the shell 1, so as to make full use of space, save resources, and combine single functional equipment. The cutting device 2 is composed of two support rods 20 connected to the top of the shell 1 and symmetrically distributed, and an electric heating wire 21 located between the top ends of the two support rods 20. The electric heating wire 21 utilizes electric energy to convert into thermal energy, so that the foam cutting surface can be made flat. The hot melt device 3 is composed of an outer shell 31, an electric heating plate 34 located in the outer shell 31, and a glue coating port 32 located outside the outer shell 31. When the glue stick is melted into a fluid, the liquid glue will flow out from the glue coating port 32.

[0028] In this embodiment, a battery compartment 10 for installing a battery is provided inside the housing 1 , and a shell cover with matching size is provided in the opening of the battery compartment 10 to protect the battery at the same time.

[0029] In this embodiment, the two support rods 20 are both L-shaped, and the two support rods 20 are fused to the arc side wall of the shell 1 near the top, so as to increase the cutting area and enhance the firmness of the support rods 20.

[0030] In this embodiment, a rectangular block is integrally formed at the center of the bottom end of the shell 1 to reduce the distance between the turntables 30 and facilitate holding. The bottom end of the shell 1 is rotatably connected to two turntables 30 on opposite sides of the rectangular block through pins. The outer shell 31 is fused and connected to the edge between the two turntables 30 to facilitate the rotation of the turntable 30 without getting stuck by the outer shell 31. The two turntables 30 are rotatably connected to the side wall of the shell 1 near the bottom for easy rotation.

[0031] In this embodiment, the shell 31 is cylindrical and has two through ends. A movable sleeve 35 is slidably connected to one end of the shell 31 near the turntable 30, and a guide sleeve 33 is fixedly connected to one end of the shell 31 near the glue coating port 32. The guide sleeve 33 is used to maintain the direction of the glue stick, and the movable sleeve 35 is used to push the glue stick outward.

[0032] In this embodiment, the glue application port 32 is conical and welded to the outer end of the guide sleeve 33 for easy glue application. An electric heating plate 34 is fixed to the arc outer wall of the guide sleeve 33 by screws, and the glue stick is melted by the electric heating plate 34. The arc side surface of the movable sleeve 35 is molten and connected with a push piece 36 for pushing the movable sleeve 35. A sliding port is also provided on the side wall of the outer shell 31 for accommodating the push piece 36 to extend to the outside and slide.

[0033] In this embodiment, the two ends of the heating wire 21 extend along the two support rods 20 to the interior of the shell 1 and are electrically connected to the positive and negative poles of the battery compartment 10 through a switch. The heating plate 34 is electrically connected to the battery compartment 10 through a wire and a switch. The switch is used to make the functions of the two devices independent, improve safety, and enable the devices to work normally.

[0034] When the utility model is used for the electric heating processing tool for the lost casting model, firstly, the battery compartment 10 is loaded with batteries, the switch of the electric heating wire 21 is turned on, and the foam can be cut after the electric heating wire 21 is heated; when the bonding function is needed, the switch of the electric heating wire 21 is turned off, and the shell 1 is held in the opposite direction after the electric heating wire 21 is cooled, and then the switch of the electric heating plate 34 is turned on, and then the glue stick is inserted from the tail end of the movable sleeve 35 in the hot melt device 3, and the pushing member 36 is pressed in the direction of the turntable 30 to move the movable sleeve 35 forward. At the same time, the glue stick will also move forward under the action of friction as the movable sleeve 35 pushes it, and when the glue stick reaches the guide sleeve 33 equipped with the electric heating plate 34, it will be hot-melted, and then flow out from the glue coating port 32 for bonding.
