Description

Technical Field

[0002] In injection molds, the main purpose of cooling is to ensure that the temperature inside and outside the mold is balanced and stable, so that the plastic can be evenly cooled and solidified during the injection molding process. This ensures more stable product molding quality and avoids problems such as warping and deformation of the product.

[0003] The power button injection mold is an injection mold specially designed for the production of power buttons. At the same time, the power button injection mold is set to have multiple chambers to mold multiple products at one time, which will result in the power button injection mold having many internal parts and a complex structure. Simply placing the mold in the air for passive cooling cannot meet actual needs. Therefore, in order to improve product quality and production efficiency, most of the time, cooling water is injected into the internal water channel of the power button injection mold for circulating cooling. When demolding, the cooling water inside the mold needs to be drained. When draining the cooling water, the user needs to manually adjust the status of multiple valves connected to the water pipes of the mold, making the overall operation steps too cumbersome, requiring more time from the user, and the overall efficiency is relatively low, which is not conducive to practical use.

The shape of the friction block 811 is arc-shaped, and the curvature of the friction block 811 is consistent with the curvature of the annular groove. In the initial state, the crank handle 83 is in a horizontal state, and the raised part of the cam 87 contacts the ball head end of the ball head rod 88, ensuring that the established structure can operate stably and reasonably, thereby achieving the pre-established purpose.

[0026] Working principle: when cooling the power button injection mold, the cooling water circulation pipe group 2 is used to circulate the cooling water inside the water-cooling body 1 into the power button injection mold for cooling. When the power button injection mold is demolded, the cooling water inside the power button injection mold is discharged through the drain pipe 3. The water-cooling body 1 is a prior art achievement, so its specific operating steps and the principles of cooling water injection and circulation will not be described in detail in this article.

[0027] In the initial state, the valve controlled by the first valve knob 5 on the cooling water circulation pipe group 2 is in the open state, and the valve controlled by the second valve knob 6 on the drain pipe 3 is in the closed state, so that the cooling water inside the water-cooled body 1 can be circulated for cooling. The first valve knob 5 and the second valve knob 6 can be turned forward to open the corresponding valves, and reverse rotation can close the valves. Figure 2 and Figure 3The first valve knobs 5 on the plurality of cooling water circulation pipe groups 2 are linked together by a first connecting rod 71 with first connecting shafts 75 at both ends, so that when a single first valve knob 5 is rotated, it can drive the plurality of first valve knobs 5 to rotate in the same direction, so that the valves on the cooling water circulation pipe group 2 are opened or closed synchronously. A first gear 72 is fixed to one of the first connecting shafts 75, and the first gear 72 is meshed with a second gear 73. The second gear 73 is linked to the second valve knob 6 through a second connecting rod 74 with second connecting shafts 76 at both ends. The size of the first gear 72 is consistent with that of the second gear 73. Therefore, the rotation direction of the first gear 72 is consistent with the rotation direction of the second gear 73, and the second gear 73 is consistent with the rotation direction of the second valve knob 6 under the connection of the second connecting rod 74. After the second gear 73 rotates forward, it will drive the second valve knob 6 to rotate forward to open the valve corresponding to the drain pipe 3. At the same time, the first gear 72 rotates reversely, driving the first valve knob 5 to rotate reversely to close the valve corresponding to the cooling water circulation pipe group 2. At this time, the components contained in the water-cooled body 1 can be used to extract the cooling water inside the power button injection mold through the drain pipe 3 to ensure stable demolding.

[0028] During actual operation, the crank handle 83 that is movable on the connecting seat 85 by the movable shaft 86 is pulled so that the crank handle 83 is in a vertical state. At this time, the cam 87 rotates with the turntable 82, and its raised part does not contact the end of the ball head rod 88. The ball head rod 88 slides on the turntable 82 by means of the slide plate 89 fixed thereto, and the slide plate 89 is further connected to the turntable 82 by means of the return spring 810. Therefore, under the elastic force of the return spring 810, the ball head rod 88 drives the friction block 811 fixed at the end to slide upward, so that the friction block 811, which has a plurality of fine grooves on its bottom surface that enhance friction and cooperate with the fixed seat 81, does not contact the fixed seat 81. , and the connecting seat 85 is fixed on the turntable 82, so the user can use the crank handle 83 to rotate the turntable 82, and the turntable 82 is fixed on the linkage shaft 84. The linkage shaft 84 rotates on the fixed seat 81 while being fixedly connected to the second gear 73. The second gear 73 will rotate with the rotation of the turntable 82. By adjusting the rotation direction of the turntable 82, the state of the corresponding valve can be adjusted using the first valve knob 5 and the second valve knob 6, thereby meeting the use requirements of mold cooling or demoulding. When the crank handle 83 is released, the crank handle 83 returns to its original position under the action of the return torsion spring 812 fixedly connected to the movable shaft 86 and the connecting seat 85 at both ends. Figure 4 In the initial position shown, the raised portion of the cam 87 contacts the ball rod 88 again, pushing the ball rod 88 to slide downward, and the surface of the friction block 811 provided with a plurality of grooves contacts and cooperates with the fixed seat 81, limiting the movement of the friction block 811, thereby limiting the rotation of the turntable 82, and further locking the state of the first valve knob 5 or the second valve knob 6.
