Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of casting molds, more particularly to a casting mold for a gearbox housing. BACKGROUND

[0002] Low pressure casting is a casting method that liquid alloy is pressed into a mold cavity from bottom to top under the action of pressure, and solidified under the action of pressure to obtain a casting. The low pressure casting equipment is generally composed of a main machine, a hydraulic system, a holding furnace, a liquid surface pressurizing device, an electrical control system, a mold cooling system and the like. The filling of the mold by the riser pipe is more complete by pressurization. However, there is a residual problem in the riser pipe after the mold cools down regardless of the change in pressure. Specifically, as follows:

[0003] I. The metal liquid is pressed into the riser pipe by the pressure difference and then enters the mold. After the liquid fills the entire mold, the pressure needs to be maintained. When the mold cools and sets, the gas pressure is recovered, and the liquid in the riser pipe flows back to the holding furnace for subsequent reuse. However, part of the metal at the top of the riser pipe will solidify and adhere to the pipe wall during the cooling of the mold. If not cleaned in time, it will affect the next casting and also has a certain corrosive effect on the riser pipe.

[0004] II. When the metal liquid is poured into the holding furnace, the air inside expands after being heated and enters the inside of the hydraulic pipe and condenses into water droplets. When the hydraulic system is started, the water droplets are pressed into the metal liquid, which will react violently due to high temperature and cause subsequent casting.

[0049] The connecting plate 232 is telescoped in the inner side of the power disc 23 and drives the installation groove 212 to rotate under the driving of the reciprocating motor 233. Since the installation groove 212 is fixed on the side of the sliding plate 21 and has the guiding effect of the T-shaped slide rail 241 and the T-shaped slide plate 242, the sliding plate 21 is driven to slide, and the pressurizing rod 22 at the bottom end of the sliding plate 21 is rigidly moved to press the gas in the inner side of the storage tank 404 into the inner part of the heat preservation tank 101; the other side of the sliding plate 21 drives the follow-up disc 243 to move in the inner side of the sliding groove 244, and the sliding disc 302 connected through the auxiliary rod 304 also slides on the side of the resistance plate 305;

[0050] For the pressurization of the inner side of the heat preservation tank 101, mainly in the liquid opening stage, the internal liquid is smoothly introduced from the heat preservation tank 101 to the gap between the lower mold 106 and the upper mold 107 through the liquid lifting pipe 104, at this time the sliding of the sliding disc 302 on the resistance plate 305 is slightly cooled by the heating state; when it is necessary to continue to increase the pressure in the filling process, and the position of the sliding disc 302 provides heat to reach the melting point of the metal; in the pressure maintaining stage, the position of the sliding disc 302 provides heat less than the melting point of the metal, at this time the mold in the inner part of the upper mold 107 is in the cooling and shaping stage, the heat production of the sliding disc 302 is reduced, which also cools the mold, and the liquid at the port of the liquid lifting pipe 104 can effectively prevent the liquid filled into the mold from flowing back to the heat preservation tank 101; when the mold cooling is completed, the pressurizing rod 22 at the top end of the storage tank 404 moves upward and brings the sliding disc 302 to the highest point, the heating of the heating resistor 306 is carried out, the metal at the port of the liquid lifting pipe 104 is melted and slides to the inner side of the heat preservation tank 101;

[0051] Reference Figure 9 The sliding disc 302 slides on the resistance plate 305, and the highest point of the resistance plate 305 is the rightmost end in the figure.

[0053] The bottom end of the micro motor 506 is fixedly connected with a rotating shaft 505, the side surface of the rotating shaft 505 is fixedly connected with a rotating ring 504, the side surface of the rotating ring 504 is fixedly connected with the side surface of the inner sealing frame 502, the side surface of the inner sealing frame 502 is fixedly connected with a sponge block 503, and the side surface of the outer sealing pipe 501 is fixedly connected with the side surface of the gas outlet pipe 405.

[0054] The condensed water appearing at the bottom end of the gas outlet pipe 405 is absorbed by the sponge block 503 at the position where the replacement mechanism 5 is located, and will not be blown back to the inside of the heat preservation tank 101 by the gas filled in the gas outlet pipe 405, the multiple sponge blocks 503 on the side surface of the rotating ring 504 can be rotated by the action of the heating resistor 306, the replacement of the sponge block 503 is started after pressure relief each time, and the outer sealing pipe 501 seals the two ends of the gas outlet pipe 405, so that the gas leakage phenomenon is avoided.

[0055] The working principle of the application is as follows: in the process of casting, the molten metal liquid is poured into the inside of the heat preservation tank 101 through the inlet pipe 102, air or inert gas is introduced into the inside through the air pipe 103, the metal liquid is sent to the inside of the upper mold 107 and the inner pressure block 108 through the action of the liquid lifting pipe 104, and the pressure is maintained by the gas pressure, and after cooling, the pressure in the heat preservation tank 101 is changed, and the remaining liquid in the liquid lifting pipe 104 flows back to the inside of the heat preservation tank 101.

[0056] The heating resistor 306 is added at the top end of the liquid lifting pipe 104, the heating temperature of the heating resistor 306 is controlled by the gas in the storage tank 404 when the gas in the storage tank 404 is inflated to the heat preservation tank 101, when the reciprocating motor 233 is started to drive the rotating rod 234 to rotate, the rotating rod 234 drives the power disc 23 to rotate, the connecting plate 232 is telescoped on the side surface of the power disc 23, and the auxiliary disc 231 is driven to move, the auxiliary disc 231 is fixed on the inside of the bearing 211 to ensure the relative sliding between the auxiliary disc 231 and the sliding plate 21, the T-shaped sliding plate 242 fixed at the bottom end of the sliding plate 21 is engaged with the work-shaped sliding rail 241 fixed on the side surface of the power disc 23, and the sliding direction of the sliding plate 21 is controlled.

[0057] The side surface of the sliding plate 21 is fixed with the pressure rod 22 at the top end of the storage tank 404 through a screw, and the side surface of the sliding plate 21 is also fixed with the follow-up disc 243, the side surface of the follow-up disc 243 is connected with the side surface of the sliding disc 302 through the auxiliary rod 304, so that when the sliding plate 21 moves, the pressure in the heat preservation tank 101 can be changed, and the temperature of the heating resistor 306 can be changed through the connection of the sliding disc 302 and the connecting head 301.

[0058] When the inside of the heat preservation tank 101 pours into the metal liquid, the water vapor in the inside of the heat preservation tank 101 is evaporated through the vent pipe 103 into the inside of the air outlet pipe 405 under the action of high temperature, and then the inside wall of the air outlet pipe 405 cools it to form condensation beads and slide to the low-lying place in the inside of the air outlet pipe 405, when the gas in the storage tank 404 is introduced into the heat preservation tank 101, the condensed liquid is easily pushed into the inside of the heat preservation tank 101, and the liquid drops into the high-temperature metal liquid will have a violent evaporation reaction;

[0059] Therefore, the outer sealing pipe 501 is fixed at the low-lying place of the air outlet pipe 405 to ensure the air tightness of the inside of the air outlet pipe 405, the inner sealing frame 502 is installed at the inside of the outer sealing pipe 501 and fixed by the micro motor 506, the inner sealing frame 502 is clamped at the broken part of the air outlet pipe 405 to improve the air tightness, and the sponge block 503 is fixed at the inside of the inner sealing frame 502 to absorb the condensation beads in the inside of the air outlet pipe 405, the rotation ring 504 is driven to rotate by the start of the micro motor 506 to replace the soaked sponge block 503, so that the inside of the sponge block 503 is kept dry.

[0060] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
