Description

Technical Field

[0002] The mold is a tool that uses a specific shape to shape the blank into a workpiece with a certain shape and size under the action of external force. After the mold is processed and formed, it is necessary to eject the workpiece formed inside the lower die seat. Usually, the ejection mechanism is installed inside the mold to eject the workpiece. The existing ejection mechanism is used for ejecting the workpiece after the mold is processed and formed. The ejection operation of the mold ejection mechanism is more uniform and the force is slowly ejected. The slow ejection during the material extraction is not easy to cause ejection damage to the processed workpiece, which improves the ejection operation effect of the mold ejection mechanism installed in the mold and the ejection quality of the workpiece;

During the ejection operation, the hydraulic cylinder runs relatively quickly to eject, which is not convenient for slow operation. The heat dissipation of the workpiece inside the mold is slow and the molding is unstable. During the fast ejection operation, the lower surface of the formed workpiece is easily damaged by ejection, thereby affecting the use effect of the mold ejection mechanism installed in the mold for ejection operation and the ejection quality of the workpiece. For this reason, the utility model proposes a mold ejection mechanism. Utility Model Content

The ejector rod 104 is arranged at the four corners and the middle position of the upper surface of the movable adjustment plate 105. The top plate 106 is arranged at the inner bottom end of the lower mold base 101, and the top end of the ejector rod 104 is fixedly connected with the lower surface of the top plate 106 by bolts. After the processing and forming, the movable adjustment plate 105 moves slowly to drive the ejector rod 104 and the top plate 106 to be evenly forced and slowly ejected. The mold ejection mechanism body 100 is also provided with:

[0035] A stabilizing control mechanism includes a sliding control component and a rolling component. The sliding control component is arranged at the connection between the end of the movable adjustment plate 105 and the inner side of the groove 102, and the rolling component is arranged inside the sliding control component. When the mold ejection mechanism body 100 ejects the workpiece processed and formed in the mold, the stabilizing control mechanism can buffer and control the movement of the movable adjustment plate 105 to drive the ejector rod 104 and the ejector plate 106 to move and eject the workpiece, thereby improving the stability of the mold ejection mechanism body 100 when it is installed inside the mold and slowly moves and ejects the workpiece.

[0036] In order to facilitate the stable control of the movable adjustment plate 105 for buffering movement and ejection operation through the sliding control component, in the present embodiment, preferably, the sliding control component includes a control slide groove 1051 opened at the two side ends inside the groove 102, and two control sliders 1052 are welded and fixed at both ends of the movable adjustment plate 105, and the control slider 1052 is consistent with the internal structure of the control slide groove 1051. When the movable adjustment plate 105 moves, it drives the control slider 1052 to slide and control inside the control slide groove 1051, so that the movable adjustment plate 105 can stably drive the ejector rod 104 and the ejector plate 106 to slowly move and eject.

[0037] In order to facilitate the smooth sliding control of the control slider 1052 in the control groove 1051 through the rolling component, in the present embodiment, preferably, the rolling component includes a rolling groove 1054 opened in the control slider 1052, and the interior of the rolling groove 1054 is connected to the ball 1053 in a rolling manner, and the outer surface of the ball 1053 contacts the inner surface of the control groove 1051. When the movable adjustment plate 105 moves to drive the control slider 1052 to slide, the sliding of the control slider 1052 drives the ball 1053 to contact the inner surface of the control groove 1051 and roll, and the ball 1053 is in the rolling groove 1054. The smooth rolling of the control slider 1052 stably controls the sliding of the control slider 1052, and the movable adjustment plate 105 is more stably moved and ejected slowly.

[0038] The model of the forward and reverse motor 1037 in the utility model is YS-70KTYZ.

[0039] The working principle and use process of the utility model: before using the mold ejection mechanism, the mold ejection mechanism body 100 can be stably placed at the processing and forming position by the lower mold base body 101 contacting the ground. After the mold ejection mechanism body 100 is processed and formed, the top plate 106 is embedded in the inner bottom end of the lower mold base body 101 to inject material into the inner part of the lower mold base body 101 for processing and forming;

[0040] Then, when the mold processes and shapes the workpiece and ejects it from the lower mold base 101, the forward and reverse motors 1037 can be operated to drive the screw rod 1038 to rotate. The screw rod 1038 rotates to move the two moving frames 1033 toward each other in the moving adjustment groove 1032. When the two moving frames 1033 move, they drive the two sets of mounting slides 1034 to move toward each other until the mounting slides 1034 slide in the supporting slide groove 1039. The sliding of the mounting slide 1034 drives the supporting inclined rod 1031 to adjust and tilt to a certain angle. The cross-adjustment ends of the two sets of supporting inclined rods 1031 drive the supporting The support slide seat 1035 slides on the outer surface of the support slide rail 1036, and moves the movable adjustment plate 105 upward steadily and slowly. The movement of the movable adjustment plate 105 drives the ejector rod 104 and the ejector plate 106 to move, and the ejector rod 104 uniformly applies force to the top of the edge and the middle position of the ejector plate 106, until the ejector plate 106 moves inside the lower mold base body 101 to uniformly apply force to the processed workpiece and slowly eject the material. When the heat dissipation of the processed workpiece is slow, it is not easy to cause damage to the workpiece, thereby improving the ejection operation effect and the ejection quality of the workpiece when the mold ejection mechanism main body 100 is installed in the mold;

[0041] Finally, when ejecting the workpiece after being processed inside the mold, the movable adjustment plate 105 drives the ejector rod 104 and the ejector plate 106 to move slowly. At this time, the movable adjustment plate 105 drives the control slider 1052 to slide inside the control slide groove 1051 when it moves slowly. When the control slider 1052 slides, it drives the ball 1053 to contact the inner surface of the control slide groove 1051 and drives the ball 1053 to roll inside the rolling groove 1054, so that the control slider 1052 can move stably to control the operation, and the movable adjustment plate 105 can move more stably and slowly, so that the ejector rod 104 and the ejector plate 106 can be stably stressed and slowly ejected, thereby improving the stability of the mold ejection mechanism main body 100 when it is installed inside the mold and slowly moves to eject.
