Description
Technical Field
The invention relates to the field of precision casting, in particular to a wax part forming die for casting.
Background
At present, in the precision casting field, a wax part needs to be manufactured as a casting mold, when the wax part is manufactured, a forming mold is used for manufacturing the wax part, a three-character die head is used for injecting wax and forming the wax part in the forming mold, the original three-character die head is usually a cylinder, the die head is heavy, the material yield cost is low, the material cost is high when a shell mold process is manufactured, the whole tree process efficiency and cost are greatly influenced by a pouring gate cup opening, and the slurry is not easily hung at the cup opening in the slurry dipping process after the tree product is assembled by the die head, so that the slurry is unevenly hung by the die head, and the thickness is uneven and the strength is insufficient. When the wax piece is transported, the die head screw is easy to enter wax due to the fact that the die head cup opening is large, and the hooking process is difficult. Therefore, the problem that the original three-word die head is high in cost and the cup opening is large is particularly important.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a wax piece forming die for casting, the wax weight of a die head is reduced through concave design, the loss of wax pieces can be reduced by more than 17%, a product is changed into concave type, the cup opening is easy to be hung from slurry compared with the prior die head in the manufacturing process of a shell mold, the strength of the shell mold is reduced due to insufficient scrapping of the shell mold, the strength of the shell mold is improved greatly, and the problems of higher cost and larger cup opening of the original three-shaped die head are solved.
The invention provides a wax piece forming die for casting, which comprises a die body, wherein a wax piece body groove and a three-shaped die head are arranged on the die body, and the three-shaped die head is arranged at one end of the wax piece body groove, and is characterized in that: the three-character die head is characterized in that the two sides of the three-character die head are provided with recesses, the three-character die head is concave through the recesses, the three-character die head is provided with groove convex strips, three grooves exist after the wax piece die head is molded through the groove convex strips, and the three-character die head is provided with a cup opening in the opposite direction of the die body.
The further improvement is that: the cup opening is flat bottom type, and the cup opening is round.
The further improvement is that: the wax injection time of the three-word die head is 22 s+/-2 s.
The further improvement is that: the cooling time of the die body is 5-10 s.
Wax injection time of die head: 22.+ -. 2S, cooling time: 5-10S, the temperature of the nozzle of the wax injection machine is: 55+/-2 ℃ and the temperature of a wax cylinder of a wax injection machine: 80.+ -. 5 ℃ and start preparation: starting the hydraulic pump, starting the manual starting switch, starting the manual nozzle to withdraw, manually feeding and discharging the die, and manually closing the die.
The operation flow of the injection die head is as follows:
spraying a release agent: the method comprises the steps of (1) mounting a die, mounting a lower die and mounting an inner core, placing a T-shaped nut on a fixing pin of the inner core, enabling two hands to leave a die clamping area, simultaneously pressing a start switch by the two hands, holding the die head by hands to rotate for 1-2 times after the setting action is recovered after the wax injection action is completed, taking down the die head, placing the die head into ice water, immersing the die head into the ice water for cooling, and drying the die head by an air gun after the die head is completely cooled.
The beneficial effects of the invention are as follows: the wax weight of the die head is reduced through the concave design, the loss of wax parts can be reduced by more than 17%, the concave design casting die head is reduced, the yield of the casting die head is improved by more than 15% compared with the prior die head, the product is changed into concave type, the cup opening is easy to be hung from slurry compared with the prior die head in the manufacturing process of the shell die, the strength of the shell die is reduced due to insufficient scrapping of the shell die, the cup opening of the die head is changed into a flat bottom type, the T-shaped nut wax feeding phenomenon can not occur in the tree combining hook, the direct latch hook operation is convenient, the operation efficiency of the hook is improved by more than 13%, and the efficiency of the manufacturing die head and the dewaxing process is improved by more than 5%.
