[0017] See also Figure 1 to Figure 2 The present embodiment provides a mechanism for a slider to be inclined and opened in different directions, including a slider seat 4 and a slider body 1 installed on the slider seat 4, a fixed block 8 is provided on one side of the upper surface of the slider body 1, a plurality of inclined tops 9 are provided on the other side of the upper surface of the slider body 1, an inclined core pull 2 is provided on the inclined top 9, a plurality of shifting blocks 7 are provided on the fixed block 8, an inclined top seat 3 is provided on the shifting block 7, and a square guide column 5 is provided on the inclined core pull 2.
[0018] The bottom of the slider body 1 is fixedly mounted on the other side of the upper surface of the slider seat 4, and a cylinder 10 is fixedly mounted at the center of one side of the slider seat 4. It should be added that the cylinder 10 is fixedly mounted at the center of one side of the slider seat 4 and is the power source for the mold opening action.
[0019] The oil cylinder 10 opens the mold once to drive the slider seat 4 and the shift block 7 to drive the inclined top seat 3 and the inclined core 2 and the inclined top 9 to retreat and completely separate from the product. The oil cylinder 10 opens the mold twice to drive the slider seat 4 and the slider body 1 to separate from the product.
[0020] The bottoms of several shift blocks 7 are fixedly installed on one side of the upper surface of the slider body 1, and the bottom of the fixed block 8 is fixedly installed on one side of the upper surface of the slider body 1. A second hole 82 with the same shape and size as the shift block 7 and plugged into each other is opened obliquely above and near the top of the fixed block 8, and the top of the shift block 7 is slidably installed in the second hole 82. It should be supplemented that: there are at least three shift blocks 7, which are respectively fixedly mounted at the center and both ends of one side of the upper surface of the slider body 1, and a first hole 31 is penetrated at the center and both ends of one side of the inclined top seat 3, and the aperture size of the first hole 31 is the same as that of the second hole 82. The top of the shift block 7 is slidably mounted in the first hole 31 and the second hole 82, and grooves are respectively opened at both ends of the center at the upper oblique side of the fixed block 8, and plug-ins with the same shape and size as the grooves and plugged into each other are fixedly installed at the centers of both ends of the other side of the inclined top seat 3, and the plug-ins are slidably installed in the grooves, and a shovel base 6 is slidably mounted at the center and both ends of the top of the fixed block 8, and a slot 81 is respectively opened at the center and both ends of the top of the fixed block 8, and a protrusion with the same size as the slot 81 and plugged into each other is fixedly installed at the center of the bottom of the shovel base 6, and the protrusion is slidably installed in the slot 81.
[0021] The shovel base 6 is pulled out to release the rear space of the inclined top seat 3. At this time, the inclined top seat 3 is pushed out by the shift block 7 and cannot move.
[0022] A plurality of slide grooves 21 are provided through the center of one side of the inclined core 2, and the slide grooves 21 are slidably mounted on the bottoms of the plurality of inclined tops 9. It should be added that the number of the plurality of slide grooves 21 is equal to the number of the plurality of inclined tops 9.
[0023] The inclined core puller 2 is a key component in the mold opening action, and is used to realize the demoulding of the mold. The design of the slideway 21 enables the inclined top 9 to smoothly push the inclined core puller 2 to move.
[0024] The bottom center of the inclined roof seat 3 is provided with a plurality of slots of the same shape and size as the tops of the inclined roofs 9 and plugged into each other, and the inclined roofs 9 are slidably mounted on the tops of the inclined roofs 9. It should be added that the number of the slots is equal to the number of the inclined roofs 9.
[0025] A groove is formed at the bottom center of the inclined top seat 3 for plugging with the top of the inclined top 9 to further stabilize the position of the inclined top 9. The inclined top seat 3 is connected to the slider body 1 through the shift block 7 to ensure the stability and accuracy of the inclined top 9 during the mold opening process.
[0026] The square guide pillars 5 are slidably mounted on the two ends of the upper surface of the inclined core pull 2, and two slots 22 are respectively provided through the centers of the two ends of the upper surface of the inclined core pull 2, and mounting plates 51 are respectively fixedly mounted on the two ends of one side of the bottom of the two square guide pillars 5, and the mounting plates 51 are slidably mounted in the slots 22. It should be supplemented that the square guide pillars 5 are mounted on the two ends of the upper surface of the inclined core pull 2 to guide and support the movement of the inclined core pull 2.
[0027] The square guide column 5 is pulled out to make the inclined core 2 retreat, and the inclined top 9 is driven by the inclined core 2 to shrink inward and separate from the product.
[0028] The specific use of the utility model is as follows: first, in the first mold opening, the oil cylinder 10 starts to work, pushing the slider seat 4 to move backward, and the movement of the slider seat 4 drives the shift block 7, the inclined top seat 3, the inclined core 2 and the inclined top 9 to retreat together. In the process of retreating, the inclined top 9 drives the inclined core 2 to shrink inward through the guidance of the slide groove 21, thereby detaching from the product. The shovel base 6 is then pulled out, releasing the rear space of the inclined top seat 3, and the inclined top seat 3 remains stable under the ejection action of the shift block 7. In the second mold opening, the oil cylinder 10 continues to work, and the second mold opening action is performed. The slider seat 4 continues to retreat, and the slider body 1 also begins to detach from the product. Since the inclined top seat 3, the inclined core 2 and the inclined top 9 have already detached from the product in the first mold opening, they no longer have an effect on the product at this time. When the mold opening is completed, the mechanism needs to be reset, the shovel base 6 is inserted back into the slot 81 of the fixed block 8, and the square guide column 5 is reinserted into the slot 22. The oil cylinder 10 drives the slider seat 4 and the slider body 1 back to the initial position, and the reset is completed.
