Description

TECHNICAL FIELD

[0001] The utility model relates to ingot casting demolding technical field, concretely is a high speed tool steel ingot casting demolding auxiliary device. BACKGROUND

[0002] The process of condensing molten steel into ingot by pouring ladle into ingot mold is also called mold casting, which is the last process of steelmaking. Qualified ingot from the steelmaking furnace must be cast into ingot or billet with certain cross-sectional shape and size, so that various steel materials can be obtained through plastic processing. Ingot casting includes a series of processes from tapping to ingot demolding and sending to soaking furnace of the roughing mill, namely, preparation before pouring, pouring, demolding, ingot finishing or hot sending, etc.

[0003] The ingot pneumatic demolding device is disclosed in publication number CN217315832U. When demolding is needed, the motor is started to drive the first movable wheel to rotate, the first movable wheel drives the second movable wheel to rotate synchronously through the transmission belt, the second movable wheel drives the threaded sleeve to rotate, and the threaded rod is limited by the limiting rod, the sliding block and the sliding groove, so that the rotation of the threaded sleeve drives the threaded rod to move up and down. The rubber plug is inserted into the inner part of the mold sleeve through the threaded rod, so that air is introduced into the mold sleeve to achieve the effect of pneumatic demolding of the product. The motor drives the first movable wheel to rotate in the opposite direction, so that the threaded sleeve rotates in the opposite direction and the threaded rod moves upward, so that the mold can be taken out. However, the following problems still exist in the actual use of the patent:

[0004] Although the ingot pneumatic demolding device can insert the rubber plug into the inner part of the mold sleeve through the threaded rod, so that air is introduced into the mold sleeve to achieve the effect of pneumatic demolding of the product, the gas cannot enter the bottom of the mold sleeve uniformly. Because the adhesion degree of the ingot and the mold sleeve is not the same, when the gas is introduced into the bottom of the mold sleeve, the gas will flow out along the gap between the ingot and the mold sleeve when the ingot and the mold sleeve are separated on one side, so that the separation of the ingot and the mold sleeve cannot be realized, thereby affecting the demolding effect.

[0005] Therefore, a high speed tool steel ingot casting demolding auxiliary device is proposed to solve the problems mentioned in the above background. Utility model content

[0006] The utility model aims at providing a high speed tool steel ingot casting demolding auxiliary device to solve the problem that the gas cannot enter the bottom of the mold sleeve uniformly, because the adhesion degree of the ingot and the mold sleeve is not the same, when the gas is introduced into the bottom of the mold sleeve, the gas will flow out along the gap between the ingot and the mold sleeve when the ingot and the mold sleeve are separated on one side, so that the separation of the ingot and the mold sleeve cannot be realized, thereby affecting the demolding effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a demolding auxiliary device for high-speed tool steel ingots, comprising a demolding mechanism and a demolding sliding plate installed at the bottom of the demolding mechanism;

At the same time, when the demolding sliding cover moves to the bottom of the heat dissipation frame, the heat of the bottom mold body can be discharged from the air holes on both sides of the heat dissipation frame, thereby improving the heat dissipation effect of the bottom mold body and facilitating better demolding of the ingot. By pulling the unlocking connecting rod, the fixing plate and the mounting sliding rod are moved.

[0020] 1. By setting up a demolding mechanism, not only can the heat dissipation frame and the bottom mold body be installed and fixed using fixing bolts, but the demolding cylinder can also drive the demolding sliding plate and the demolding ejector rod to move up and down. The demolding spring assembly at the top of the demolding ejector rod can drive the air hole ejector slide plate to move up and down. The air hole ejector slide plate can be used to demold the ingot. A certain airflow is generated by the demolding air pump, and the airflow is used to demold the ingot through the air hole ejector slide plate. At the same time, when the demolding sliding cover moves to the bottom of the heat dissipation frame, the heat of the bottom mold body can be discharged from the air holes on both sides of the heat dissipation frame, thereby improving the heat dissipation effect of the bottom mold body and facilitating better demolding of the ingot. The air holes inside the air hole ejector slide plate are small, so the ingot will not flow out.

[0021] 2. By setting up a mold closing mechanism, the mold closing motor can drive the sprocket transmission assembly and the mold closing rotating rod to rotate, which in turn drives the bevel gear transmission assembly and the lifting threaded rod to rotate. At the same time, the lifting threaded sleeve drives the lifting plate, the top mold mounting bracket, and the top mold body to move up and down, thereby realizing the merging or separation of the top mold body and the bottom mold body. By pulling the unlocking connecting rod, the fixed plate and the mounting sliding rod can be moved. When the mounting pin is separated from the top mold body, the installation and disassembly of the top mold body can be realized. Attached Figure Description

The mold closing motor 203 drives the sprocket transmission assembly 204 and the mold closing rotating rod 205 to rotate. The mold closing rotating rod 205 drives the bevel gear transmission assembly 206 and the lifting threaded rod 207 to rotate. At the same time, the lifting threaded sleeve 208 drives the lifting plate 209, the top mold mounting bracket 210 and the top mold body 218 to move up and down, thereby realizing the merging or separation of the top mold body 218 and the bottom mold body 105.

[0032] Working principle: Before using this high-speed tool steel ingot demolding auxiliary device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, firstly, the heat dissipation frame 102 and the bottom mold body 105 are installed and fixed using fixing bolts 104. Simultaneously, the demolding cylinder 108 drives the demolding sliding plate 107 and the demolding ejector rod 114 to move up and down. The demolding spring assembly 115 at the top of the demolding ejector rod 114 drives the air hole ejection slide plate 106 to move up and down, achieving demolding of the ingot using the air hole ejection slide plate 106. A certain airflow is generated by the demolding air pump 113, and the airflow is used to demold the ingot through the air hole ejection slide plate 106. Simultaneously, when the demolding sliding cover 116 moves to the bottom of the heat dissipation frame 102, the heat of the bottom mold body 105 can be discharged from the air holes on both sides of the heat dissipation frame 102, thereby improving the heat dissipation effect of the bottom mold body 105 and facilitating heat dissipation. To facilitate better demolding of the ingot, the pores inside the ejector plate 106 are small, preventing ingot leakage. Secondly, the mold closing motor 203 drives the sprocket transmission assembly 204 and the mold closing rotating rod 205 to rotate, which in turn drives the bevel gear transmission assembly 206 and the lifting threaded rod 207 to rotate. At the same time, the lifting threaded sleeve 208 drives the lifting plate 209, the top mold mounting bracket 210, and the top mold body 218 to move up and down, thereby realizing the merging or separation of the top mold body 218 and the bottom mold body 105. By pulling the unlocking connecting rod 217, the fixing plate 215 and the mounting sliding rod 214 are moved. When the mounting pin 216 separates from the top mold body 218, the installation and disassembly of the top mold body 218 can be realized.
