[0026] The following refers toFigures 1 to 3 Describe a mold waterway plugging structure according to an embodiment of the present utility model.

[0027] A mold waterway plugging structure according to an embodiment of the present utility model is as follows Figures 1 to 3As shown in the figure, it includes a mold core 100 and a plugging component 300. A number of water channels 200 are arranged in the mold core 100. The ends of the water channels 200 are provided with breaks, and the breaks are plugged by the plugging component 300. The repair is simple, the repair cost is low, and after the repair, the original water channel scheme can be maintained without affecting the product quality. The plugging component 300 includes a plugging sleeve 330, a first support member 310 and a second support member 320. The plugging sleeve 330 is arranged in the break. The plugging sleeve 330 is provided with an inner cavity with an upper opening. The first support member 310 and the second support member 320 enter the inner cavity of the plugging sleeve 330 from the upper opening of the plugging sleeve 330. Specifically, the first support member 310 and the second support member 320 are arranged in the inner cavity from top to bottom. Since the outer diameter of the second support member 320 is larger than the inner diameter of the inner cavity, when the second support member 320 enters the inner cavity of the plugging sleeve 330, the plugging sleeve 330 will undergo a primary tightening deformation. The plugging sleeve 330 deforms under the action of the second support member 320 and abuts against the break of the water channel 200 to complete the sealing of the break. After the second support member 320 is placed in the inner cavity, the first support member 310 is placed in the inner cavity. Since the outer diameter of the first support member 310 is larger than the outer diameter of the second support member 320, when the first support member 310 enters the inner cavity of the plugging sleeve 330, the plugging sleeve 330 will undergo a secondary tightening deformation. The plugging sleeve 330 deforms under the action of the first support member 310 and abuts against the break of the water channel 200 to improve the sealing effect of the plugging sleeve 330 on the break. It should be noted that a number of first deformation lines 331 are arranged on the outer wall of the plugging sleeve 330. The arrangement of the first deformation lines 331 enables a gap to exist between the plugging sleeve 330 and the break. When the first support member 310 and the second support member 320 tighten the plugging sleeve 330, the existence of the gap enables the plugging sleeve 330 to have sufficient margin during deformation, ensuring the smooth progress of the deformation and abutment. It can be understood that the first support member 310 and the second support member 320 are arranged in the inner cavity from top to bottom. When the second support member 320 is placed in the inner cavity of the plugging sleeve 330, the position of the second support member 320 is in the middle of the inner cavity, and the primary tightening deformation of the plugging sleeve 330 mainly acts on the middle part of the plugging sleeve 330; when the first support member 310 is placed in the inner cavity of the plugging sleeve 330, since the first support member 310 and the second support member 320 are arranged from top to bottom, the position of the first support member 310 is in the upper part of the inner cavity. At this time, the secondary tightening deformation of the plugging sleeve 330 mainly acts on the upper part of the plugging sleeve 330, and the sealing effect of the upper part of the plugging sleeve 330 is better. Specifically, in some embodiments, the material of the plugging sleeve 330 is set as carbon structural steel. Carbon structural steel has good plasticity, toughness and cold deformation performance. Using carbon structural steel to make the plugging sleeve 330 can ensure that the plugging sleeve 330 has good plasticity, toughness and cold deformation performance, enabling the plugging sleeve 330 to be deformed under the action of the first support member 310 and the second support member 320 to plug the break.

[0028] According to some embodiments of the present utility model, the first support member 310 is arranged as a plug head, and a second deformation pattern 311 is arranged on the outer wall of the plug head. The first support member 310 is arranged as a plug head. The first support member 310 is arranged at the upper part of the inner cavity. The outer diameter of the second support member 320 is larger than the inner diameter of the inner cavity, and the outer diameter of the first support member 310 is larger than the outer diameter of the second support member 320. In order to ensure that the plug head can smoothly enter the inner cavity of the sealing sleeve 330, the second deformation pattern 311 is arranged on the outer wall of the plug head. The arrangement of the second deformation pattern 311 enables a gap to exist between the plug head and the inner cavity. When the plug head enters the inner cavity, the existence of the gap provides sufficient allowance for the deformation of the sealing sleeve 330, ensuring that the sealing sleeve 330 can deform smoothly to block the break.

[0029] Specifically, in some embodiments, the plug head is arranged as a frustum of a cone, and the diameter of the upper end portion of the plug head is larger than the diameter of the lower end portion. The plug head is arranged as a frustum of a cone, and the diameter of the upper end portion of the plug head is larger than the diameter of the lower end portion. When the plug head enters the inner cavity of the sealing sleeve 330 from top to bottom, the plug head with a gradually increasing diameter from bottom to top can gradually tighten the sealing sleeve 330, enabling the plug head to smoothly enter the inner cavity while gradually tightening the sealing sleeve 330.

[0030] According to some embodiments of the present utility model, an indentation 312 is arranged at the upper end portion of the plug head. The indentation 312 is arranged to be recessed downward. The diameter of the upper end portion of the plug head is larger than the diameter of the lower end portion. When the plug head enters the inner cavity of the sealing sleeve 330 from top to bottom, the upper end portion of the plug head can tighten the sealing sleeve 330 to deform the sealing sleeve 330 to block the break. Due to the interaction of forces, the upper end portion of the plug head will also be subjected to the inward pressing force of the sealing sleeve 330. The arrangement of the indentation 312 enables the compression deformation of the plug head to proceed smoothly, enabling the plug head to smoothly enter the inner cavity. Specifically, in some embodiments, the material of the first support member 310 is set as stainless steel.

[0031] According to some embodiments of the present utility model, the second support member 320 is arranged as a plug ball, and the plug ball is arranged as a sphere. The second support member 320 is arranged in the middle of the inner cavity. The outer diameter of the plug ball is larger than the inner diameter of the inner cavity. When the plug ball enters the inner cavity of the sealing sleeve 330, it will cause the sealing sleeve 330 to undergo an initial tightening deformation. The sealing sleeve 330 deforms under the action of the plug ball and abuts against the break of the water pipeline 200 to complete the sealing of the break. The second support member 320 is arranged as a spherical plug ball. The spherical structure can not only ensure the tightening effect of the outer diameter on the sealing sleeve 330 but also reduce the contact area between the plug ball and the sealing sleeve 330, enabling the plug ball to smoothly enter the inner cavity. Specifically, in some embodiments, the material of the second support member 320 is set as stainless steel.

[0032] According to some embodiments of the present utility model, an interference fit is provided between the plug sleeve 330 and the water pipeline 200. By setting an interference fit between the plug sleeve 330 and the water pipeline 200, the tolerance of the interference fit can ensure that the plug sleeve 330 closely fits on the inner wall of the water pipeline 200, thus ensuring the plugging effect.

[0033] According to some embodiments of the present utility model, glue is applied to the outer wall of the plug sleeve 330. When glue is applied to the outer wall of the plug sleeve 330 and the plug sleeve 330 is installed at the break at the end of the water pipeline 200 with the outer wall of the plug sleeve 330 abutting against the inner wall of the water pipeline 200, the glue can improve the connection strength between the plug sleeve 330 and the water pipeline 200 and enhance the sealing performance.

[0034] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
