Description
Technical Field
[0001] The utility model relates to a slide block anti-drop and abnormal movement structure, belonging to the technical field of mold design. Background Art
[0002] At present, with the development of science and technology, the running shoes in sports goods have become more complicated, and more and more shoes need to be demolded by sliders. In the design process of the running shoe embryo mold, the heel of the embryo shoe sometimes protrudes, but in order to be able to stably form the required special structure in the subsequent shaping and foaming, the protruding part is often not completely smoothed. Designing according to the previous design method will lead to difficulties in removing parts in actual production, and even the mold will scratch the embryo. Therefore, the core-pulling slider can only be used to demold the embryo. However, during the production process, the core-pulling slider moves to the wrong position due to gravity or the shaking of the mold when opening the mold, causing the slider to break the front mold oblique guide column when closing the mold. At this time, a method is needed that can complete the core pulling to ensure normal production without changing the slider structure, and can also solve the mold damage caused by the movement of the core-pulling slider and try not to increase the development cost.
[0003] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a slider anti-fall and abnormal movement structure to make it more valuable for industrial use. Summary of the invention
[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a slide block anti-falling and abnormal movement structure.
[0005] The utility model discloses a slider anti-fall and abnormal movement structure, comprising a mold B plate, a slider rail is provided on the front end upper surface of the mold B plate, a slider body is installed in the slider rail groove so as to slide back and forth, a screw hole connected with an equal height screw is provided at the bottom of the slider body, the equal height screw passes through a gasket and a rectangular coil spring in sequence and penetrates through the through hole in the gasket and is threadedly connected with the slider body, a protective block is also provided below the equal height screw and parallel to the same, and the protective block is connected to the front end surface of the mold B plate through a hexagon socket screw.
[0006] Furthermore, an inclined guide post sliding hole is arranged inside the slider body and tilted backward, and a front mold inclined guide post is movably arranged inside the inclined guide post sliding hole.
[0007] Furthermore, the top of the front mold inclined guide column is fixedly connected to the inclined guide column fixing block, and the inclined guide column fixing block is fixed on the front mold of the mold.
[0008] Furthermore, the slider body is provided with slider limiting steps on both sides. The slider limiting steps on both sides of the slider body are pressed and limited by two slider limiting pressing blocks, so that the slider body can only move forward and backward in the horizontal direction under the lifting force of the front mold inclined guide column;
[0009] Furthermore, the height of the slider limiting step is equal to the height of the slider rail.
[0010] Furthermore, the slider limiting pressing block is fixedly mounted on the top surfaces of both sides of the slider rail by screws, and the slider limiting step is pressed by the edge to limit the position.
[0011] Furthermore, the protection block is an "L"-shaped structure, and the protection surface area of the protection block is larger than the diameter of the rectangular coil spring, so as to prevent the rectangular coil spring from bouncing off due to fatigue damage of the screw hole and ensure the safety of the operator.
[0012] Furthermore, the height-conforming screw has the function of limiting and supporting the needle. A gasket is also arranged on the height-conforming screw to increase the contact area of the end of the rectangular coil spring to prevent the rectangular coil spring from being subjected to uneven force;
[0013] When the mold is open during the production process, the rectangular coil spring returns to its natural state from the compressed state to pull the slider body, ensuring that the slider body remains relatively stationary during the cycle from mold opening to mold closing. When the mold is closed again, the falling position of the bottom end of the front mold inclined guide column is fixed, thereby avoiding shear damage to the front mold inclined guide column due to misalignment of the slider body during mold closing, thus providing guarantee for the safe production of the mold.
[0014] Furthermore, the contour screw is threadedly connected to the slider body, and the axial direction of the contour screw is consistent with the movement direction of the slider body.
[0015] By means of the above scheme, the present invention has at least the following advantages:
[0016] This structure is very simple and convenient in the design process. Rectangular coil springs, equal height screws, and hexagon socket screws are all standard parts that can be purchased in stores. Pads and protective blocks are all flat parts without complicated processing technology. All parts only need to ensure that the design normal of the mechanism is consistent with the movement direction of the slider body. This mechanism is easy to install and maintain. The entire mechanism can be installed on the mold with 3 screws and put into use. The tension of the rectangular coil spring of this structure can provide core pulling assistance for the core pulling system where the structure is located during the mold opening process, reduce the shear force on the inclined guide column, thereby extending the life of the inclined guide column to ensure safe production and reduce production costs.

DETAILED DESCRIPTION
[0024] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0025] See also Figures 1 to 4 , a slider anti-fall and abnormal movement structure described in an embodiment of the utility model includes: a mold B plate 110, a slider rail 1101 is provided on the front upper surface of the mold B plate 110, a slider body 1 is installed in the groove of the slider rail 1101 so as to slide forward and backward, a screw hole connected to the equal height screw 3 is provided at the bottom of the slider body 1, and the equal height screw 3 passes through the gasket 5 and the rectangular coil spring 4 in sequence and penetrates the through hole in the gasket 3 and is threadedly connected to the slider body 1. A protective block 6 is also provided below the equal height screw 3 and parallel to it, and the protective block 6 is connected to the front surface of the mold B plate 110 through the hexagon socket screw 7;
[0026] The slider body 1 is provided with an inclined guide post sliding hole tilted backward inside, and a front mold inclined guide post 8 is movably provided inside the inclined guide post sliding hole, and the top of the front mold inclined guide post 8 is fixedly connected to an inclined guide post fixing block 9, and the inclined guide post fixing block 9 is fixed on the front mold of the mold;
[0027] The slider body 1 is provided with slider limiting steps 101 on both sides, and the slider limiting steps 101 on both sides of the slider body 1 are pressed and limited by two slider limiting pressing blocks 10, so that the slider body 1 can only move forward and backward in the horizontal direction under the lifting force of the front mold inclined guide column 8;
[0028] The height of the slider limiting step 101 is equal to the height of the slider rail 1101 , and the slider limiting pressing block 10 is fixedly installed on the top surfaces of both sides of the slider rail 1101 by screws, and the slider limiting step 101 is limited by its edge.
[0029] The protection block 6 is an "L"-shaped structure, and the protection surface area of the protection block 6 is larger than the diameter of the rectangular coil spring 4. This prevents the rectangular coil spring 4 from bouncing off due to fatigue damage of the screw hole, thereby ensuring the safety of the operator.
[0030] The height-conforming screw 3 has the functions of limiting and supporting the needle. A gasket 2 is also arranged on the height-conforming screw 3 to increase the contact area of the end of the rectangular coil spring 4 to prevent the rectangular coil spring 4 from being subjected to uneven force.
[0031] When the mold is open during the production process, the rectangular coil spring 4 recovers from the compressed state to the natural state to pull the slider body 1, ensuring that the slider body 1 remains relatively stationary during the cycle from mold opening to mold closing. When the mold is closed again, the falling position of the bottom end of the front mold inclined guide column 8 is fixed, thereby avoiding shear damage to the front mold inclined guide column 8 due to misalignment of the slider body 1 during mold closing, thereby providing guarantee for the safe production of the mold.
[0032] The height-conforming screw 3 is threadedly connected to the slider body 1 , and the axial direction of the height-conforming screw 3 is consistent with the movement direction of the slider body 1 .
[0033] The selection of the rectangular coil spring 4 should meet the following two points.
[0034] 1. Specifications. The rectangular coil spring should meet the requirements of tension and service life when selecting. As shown in this figure, the rectangular coil spring model is NT-SWF20-60 of the MISUMI brand, and the material is oil-cooled tempered spring steel. The spring constant N / mm{kgf / mm} of this model is 10.5{1.07}, the clamping length lmin is 27.0mm, the stroke of the slider body is 6mm, and the limit distance provided between the equal height screws and the gasket and the pad is 33mm. In summary, the rectangular coil spring selected above has a compression length of 33mm when the mold is closed, a compression length of 48mm when the mold is opened, a maximum compression distance of 27mm, and a maximum compression ratio of 45%. According to the official data provided by MISUMI, F=L*45% and a service life of 500,000 times. The service life of the rectangular coil spring selected in this example is about 500,000 times, which meets the production life requirements of the mold. The pulling force provided when opening the mold is 12*10.5=126N, the mass of the slider body is 2.6kg and the gravity it is subjected to is 26N, which fully meets the requirements.
[0035] Second, during installation, the inner diameter of the selected rectangular coil spring should be slightly larger than the outer diameter of the screw of the equal height screw, and it is not advisable to use a rectangular coil spring that exceeds the specification, which will cause workers to be unable to compress the rectangular coil spring to the usable length during assembly. At the same time, using a rectangular coil spring that exceeds the specification will increase the maximum external dimensions of the mold, greatly increasing the cost of the mold during production and transportation.
[0036] The working principle of the utility model is as follows:
[0037] During actual use of the slider anti-drop and abnormal movement structure of the utility model, when the front mold of the mold is opened, the slider body 1 moves along the set core-pulling direction under the action of the front mold inclined guide pillar 8 until the product is completely pulled out. At this time, the mold has been fully opened, and the slider body 1 cannot have other movements, otherwise it will cause the bottom end of the front mold inclined guide pillar 8 to fail to accurately enter the corresponding inclined guide pillar sliding hole on the slider body 1 during the mold closing process, but directly press on the upper surface of the slider body, thereby causing the front mold inclined guide pillar 8 to break, and the slider body 1 to be crushed and deformed, resulting in scrap. The function of this structure is to give the slider body 1 an additional external force after the mold is opened to keep it in the last action position after the front mold inclined guide pillar is opened. It is ensured that the front mold inclined guide pillar smoothly and accurately enters the corresponding inclined guide pillar sliding hole of the slider body during mold closing, so that the slider body moves from the mold opening state position to the mold closing injection position.
[0038] The slider body 1 is in the mold opening position under the force of the rectangular coil spring 4. By standing up or shaking the B plate, check whether the structure can ensure that the slider body 1 is in the mold opening position without slipping or moving. Manually push the slider body 1 to the mold closing state to check whether the tension of the rectangular coil spring 4 can pull the slider body 1 to the mold opening position.
[0039] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may change;
[0040] Secondly: In the drawings of the embodiments disclosed in the present utility model, only the structures related to the embodiments disclosed in the present utility model are involved, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;
[0041] Finally: The above description is only a preferred implementation mode of the present utility model and is not intended to limit the present utility model. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present utility model.
