Description

Technical Field

[0001] The utility model relates to the technical field of casting molds, and more particularly to a casting mold for a sealed high-temperature water chamber. Background Art

[0002] The car water chamber is a cooling system of the car, which is mainly a large water tank. The water tank is divided into upper and lower water chambers. The upper and lower water chambers are both in two halves. The upper and lower water chambers are mostly made by casting. The cast upper and lower water chambers have a certain high temperature resistance. Then the two lower halves are equipped with flat tubes and heat sinks. The oven is welded and the end cover of the water chamber is riveted with a rubber pad to form a complete water tank. The water tank welded by the upper and lower water chambers, flat tubes and heat sinks has a certain sealing and high temperature resistance.

[0003] When casting a sealed high-temperature water chamber, the upper mold and the lower mold are first tightly fitted together, and then the fluid casting material is poured into the interior of the upper mold and the lower mold through the pouring port. After preliminary cooling by the cooling system inside the upper mold and the lower mold, a water chamber is formed. Then the upper mold is lifted. Since the mold has a certain weight, the water chamber will remain inside the lower mold, and the staff is required to take out the water chamber inside the lower mold. Since the lower mold and the cast water chamber still have a certain temperature, it is easy to cause damage to the staff's hands for a long time. If the staff wears anti-scalding gloves, it is inconvenient to take out the water chamber inside the lower mold, thereby reducing the practicality and safety of the casting mold.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a casting mold for sealing a high-temperature water chamber, which has the following beneficial effects:

[0017] 1. After the water chamber is cast, the upper mold is lifted to the highest point through the lifting mechanism, and then the pipe is pulled to move forward to separate the fixed column from the fixed groove. Then the pipe is rotated, and the pipe drives the square column, the rotating shaft and the lower mold to rotate, and the lower mold is rotated 180 degrees. At this time, the water chamber inside the lower mold falls due to the action of gravity, so that it is easy to remove the water chamber from the inside of the lower mold, which avoids people removing the cast water chamber by hand, and avoids the staff's hands from being in contact with the hot water chamber for a long time, thereby improving its practicality and safety.

During this process, people's hands can be prevented from coming into contact with the cast water chamber, thereby further protecting the hands of the workers.

[0019] 3. After the water chamber falls on the conveyor, air is blown through the blowing equipment connected to the outside of the ventilation pipe to blow cold air into the ventilation box and onto the conveyor through multiple ventilation holes, so as to further cool the water chamber on the conveyor and prevent the personnel in the next process from coming into contact with the water chamber with a higher temperature and causing harm to their hands.

Two fixing plates 11 are symmetrically fixedly connected to the second fixing ring 9, and the rear ends of the two fixing plates 11 are fixedly connected to fixing columns 12. The front end of the fixed frame 1 is provided with fixing grooves 13 at positions corresponding to the two fixing columns 12. A limiting groove 15 is provided at the top of the pipe fitting 8, and a limiting column 16 is provided for sliding inside the limiting groove 15. The limiting column 16 is fixedly connected to the square column 6 by a screw 17, which is convenient for limiting the pipe fitting 8.

[0030] Specifically, when the casting groove of the lower mold 3 is rotated to the top, the pulling force on the handle 14 is reduced, and the second fixing ring 9, the pipe fitting 8, the two fixing plates 11 and the two fixing columns 12 are pulled to the rear side by the tension spring 10, so that the two fixing columns 12 are respectively inserted into the corresponding fixing grooves 13, which is convenient for fixing the lower mold 3. After the water chamber casting is completed, the upper mold 2 is lifted to the highest point by the lifting mechanism, and then the pipe fitting 8 is pulled to move to the front side, and the fixing columns 12 are separated from the fixing grooves 13, and then the pipe fitting 8 is rotated. The pipe fitting 8 drives the square column 6, the rotating shaft 5 and the lower mold 3 to rotate, and the lower mold 3 is rotated 180°. At this time, the water chamber inside the lower mold 3 falls due to the action of gravity, so that it is convenient to remove the water chamber from the inside of the lower mold 3, which avoids people from removing the cast water chamber by hand, and avoids the staff's hands from being in contact with the hot water chamber for a long time, causing hand injuries, thereby improving its practicality and safety.

[0031] See also Figure 1 and Figure 3A conveyor 21 is placed under the lower mold 3. The top front side and the top rear side of the conveyor 21 are fixedly connected with baffles 22.

[0035] In summary, when the overall equipment is in use:

[0036] When the casting groove of the lower mold 3 is rotated to the top, the pulling force on the turning handle 14 is reduced, and the second fixing ring 9, the pipe fitting 8, the two fixing plates 11 and the two fixing columns 12 are pulled to the rear side by the tension spring 10, so that the two fixing columns 12 are respectively inserted into the corresponding fixing grooves 13 to fix the lower mold 3. Then, the top plate 19, the four connecting columns 20 and the upper mold 2 are pulled downward by the four electric cylinders 18, and the upper mold 2 is made to fit tightly with the lower mold 3. Then, the fluid material is poured into the upper mold 2 and the lower mold 3. After preliminary cooling by the cooling system inside the upper mold 2 and the lower mold 3, a water chamber is formed. After the water chamber casting is completed, the upper mold 2 is lifted to the highest point by the lifting mechanism. At this time, due to gravity, the water in the water chamber remains in the lower mold 3. Then the pipe fitting 8 is pulled to the front side, and the fixing columns 1 2 is separated from the fixing groove 13, and then the pipe fitting 8 is rotated. The pipe fitting 8 drives the square column 6, the rotating shaft 5 and the lower mold 3 to rotate, and the lower mold 3 is rotated 180 degrees. At this time, the water chamber inside the lower mold 3 falls due to the action of gravity, so that it is easy to take the water chamber out from the inside of the lower mold 3. If there are individual water chambers that are difficult to fall off, the cast water chambers can be gently shoveled off from the inside of the upper mold 2 and the lower mold 3 by using the corresponding shovel tool. The fallen water chambers fall onto the conveyor 21, and the water chambers are slowly conveyed to the next process through the conveyor 21. At the same time, the air blowing equipment connected to the outside of the vent pipe 26 is used to blow air, and the cold air is blown into the inside of the vent box 25, and blown onto the conveyor 21 through multiple vent holes 24, so as to further cool the water chambers on the conveyor 21. Then the cast upper and lower water chambers, flat tubes and heat sinks are welded into a sealed and high-temperature resistant water tank.

[0037] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
