Description
Technical Field
[0001] The utility model relates to the field of mold equipment, in particular to a sliding core-pulling structure. Background Art
[0002] When processing products with existing molds, the slider inside the mold usually only has one core pulling operation. If the thickness and strength of the inclined top are not enough, it is easy to cause the inclined top to break due to forced pulling, which is not conducive to the product yield. Utility Model Content
[0003] The purpose of the utility model is to provide a sliding core-pulling structure for increasing the product yield.
[0004] In order to solve the above technical problems, the utility model provides a sliding core-pulling structure, including a slider body, a first slider seat connected to one side of the slider body, a second slider seat arranged on one side of the slider body and located outside the first slider seat, a slider insert arranged on the second slider seat, and a slider inner pull-out rod arranged on the first slider seat. The slider inner pull-out rod is movably placed inside the slider insert. A plug screw is passed through the inside of the slider body and connected. One end of the plug screw is connected to the second slider seat, and the other end has a limiting part. The limiting part is located outside the slider body and has a gap with the slider body. When the slider body drives the first slider seat to move, the slider inner pull-out rod contracts and moves relative to the inside of the slider insert. When the slider body moves and contacts the limiting part, the slider body drives the second slider seat to move.
[0005] Furthermore, the slider inner pulling rod is movably connected to the slider inner core pulling devices on both sides of one end away from the first slider seat. The slider inner core pulling devices are movably placed on the side of the slider insert, and the ends of the slider inner core pulling devices are protruding from the outer surface of the slider insert. When the slider inner pulling rod contracts and moves relative to the inside of the slider insert, the slider inner core pulling devices contract and move relative to the slider insert.
[0006] Furthermore, the side of the slider's inner pull-out rod connected to the slider's inner core pull-out is set in an inclined surface. When the slider's inner pull-out rod retracts and moves relative to the inside of the slider insert, the slider's inner core pull-out moves along the inclined surface on one side of the slider's inner pull-out rod, so that the end of the slider's inner core pull-out is retracted to the inside of the slider insert.
[0007] Furthermore, a limit block is provided on one side of the second slider seat, and a limit surface is provided on the side of the second slider seat close to the limit block. When the slider body drives the first slider seat to move, the limit block contacts the limit surface. When the slider body drives the second slider seat to move, the limit block moves away from the second slider seat.
[0008] Furthermore, the first slider seat has an oblique contact surface on one side close to the limit block. When the slider body drives the first slider seat to move, the oblique contact surface pushes the limit block to move away from the second slider seat.
[0009] Furthermore, a side of the limit block away from the second slider seat is connected to the limit seat, the limit block can move relative to the limit seat, and an elastic member is connected between the limit block and the limit seat.
[0010] Furthermore, the side of the first slider seat connected to the inner pull-out rod of the slider is arranged in an inclined surface.
[0011] Furthermore, the side of the second slider seat connected to the slider insert is arranged in an inclined surface.
[0012] Furthermore, a driving member is connected to one side of the slider body.
[0013] The beneficial effect of the present invention is that when the slider core pulling step needs to be performed inside the mold, the slider body is driven to move, so that the slider body first drives the first slider seat to move, so that the first slider seat synchronously drives the pulling rod in the slider to move, forming the first sliding core pulling step, and then when the slider body continues to move and contacts the limiting part, the slider body drives the second slider seat to move by driving the limiting part, and the second slider seat drives the slider insert to move, forming the second sliding core pulling step, so that there are a total of two sliding core pulling steps in the moving stroke of the slider body, thereby avoiding the problem of forced pulling of the inclined top to form a break due to a single sliding core pulling, thereby increasing the yield rate of the product.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.
[0022] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.
[0023] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0024] like Figure 1-6 The utility model provides a sliding core-pulling structure, including a slider body 1, a first slider seat 2 connected to one side of the slider body 1, a second slider seat 3 arranged on one side of the slider body 1 and located outside the first slider seat 2, a slider insert 4 arranged on the second slider seat 3, and a slider inner pulling rod 5 arranged on the first slider seat 2. The slider inner pulling rod 5 is movably placed inside the slider insert 4. A plug screw 6 is connected to the inside of the slider body 1. One end of the plug screw 6 is connected to the second slider seat 3, and the other end has a limiting part 7. The limiting part 7 is located outside the slider body 1 and has a gap with the slider body 1. When the slider body 1 drives the first slider seat 2 to move, the slider inner pulling rod 5 contracts and moves relative to the inside of the slider insert 4. When the slider body 1 moves and contacts the limiting part 7, the slider body 1 drives the second slider seat 3 to move.
[0025] When the slider core pulling step is required inside the mold, the slider body is driven to move, so that the slider body first drives the first slider seat to move, so that the first slider seat synchronously drives the pulling rod in the slider to move, forming the first sliding core pulling step. Then, when the slider body continues to move and contacts the limiting portion, the slider body drives the second slider seat to move by driving the limiting portion, and the second slider seat drives the slider insert to move, forming the second sliding core pulling step, so that there are a total of two sliding core pulling steps in the moving stroke of the slider body, thereby avoiding the problem of forced pulling of the inclined top to form a break due to a single sliding core pulling, thereby increasing the yield rate of the product.
[0026] In particular, since there is a gap between the limiting portion and the slider body, when the slider body initially moves, the slider body will only drive the first slider seat to move, and will not drive the second slider seat to move at the same time. After the slider body moves a certain distance so that the slider body contacts the limiting portion, the slider body drives the driving screw to move through the limiting portion, and then drives the second slider seat to move through the driving screw, thereby forming a secondary segmented core pulling movement.
[0027] In one embodiment of the present scheme, one side of the first slider seat 2 connected to the slider inner pull-out rod 5 is set in an inclined surface, and the slider inner pull-out rod is movably set on the slider insert. When the first slider seat is driven to move by the slider body, the slider inner pull-out rod is pulled along the inclined surface by the inclined surface on one side of the first slider seat, and then the slider inner pull-out rod moves relative to the slider insert under the drive of the inclined surface. On the basis of ensuring that the slider inner pull-out rod is movable, the core-pulling movement direction of the slider inner pull-out rod can be adjusted by the inclination of the inclined surface.
[0028] Similarly, in one embodiment of the present scheme, the side of the second slider seat 3 connected to the slider insert 4 is set in an inclined surface, and the pulling rod in the slider is movably set in the mold, so that when the second slider seat moves, the slider insert also moves through the inclined surface, so that the slider insert moves relative to the mold under the drive of the inclined surface. On the basis of ensuring that the slider insert is movable, the core pulling movement direction of the slider insert can be adjusted by the inclination of the inclined surface.
[0029] In particular, in this solution, the inclined surfaces on the first slider seat and the second slider seat have the same inclination angle, so that the slider insert and the draw rod in the slider have the same inclined movement direction.
[0030] Among them, a driving member 13 is connected to one side of the slider body 1, which drives the slider body to move to ensure the stable operation of the overall sliding core-pulling structure. In one embodiment of this scheme, the driving member is a cylinder, and one side of the slider body is connected to the output shaft of the cylinder.
[0031] Preferably, the slider inner pulling rod 5 is movably connected to the slider inner core pulling parts 8 on both sides of one end away from the first slider seat 2. The slider inner core pulling parts 8 are movably placed on the side of the slider insert 4, and the ends of the slider inner core pulling parts 8 are protruding from the outer surface of the slider insert 4. When the slider inner pulling rod 5 contracts and moves relative to the inside of the slider insert 4, the slider inner core pulling parts 8 contract and move relative to the slider insert 4.
[0032] Specifically, the end of the slider core puller 8 is protruding from the outer surface of the slider insert 4, so that when the product is sleeved on the outer end of the slider insert, not only can the product be limited and connected by the slider insert, but the inner side of the product can also be inverted by the end of the slider core puller protruding from the outer surface of the slider insert. When the first slider seat drives the slider inner puller rod to retract and move relative to the inside of the slider insert, the slider core puller simultaneously retracts and moves relative to the slider insert, so that the end of the slider core puller is separated from the position of the inverted product, thereby making the product preliminarily unlocked during one sliding core pulling step.
[0033] Preferably, the side of the slider inner pull-out rod 5 connected to the slider inner core pulling device 8 is set at an inclined surface. When the slider inner pull-out rod 5 is retracted and moved relative to the inside of the slider insert 4, the slider inner core pulling device 8 moves along the inclined surface on one side of the slider inner pull-out rod 5 so that the end of the slider inner core pulling device 8 is retracted to the inside of the slider insert 4.
[0034] Specifically, when the pull-out rod in the slider moves relative to the inside of the slider insert, since the core pull-out part in the slider is movably placed on the side of the slider insert, and the side of the pull-out rod in the slider connected to the core pull-out part in the slider is arranged at an inclined surface, the core pull-out part in the slider will move along the inclined surface, and then the end of the core pull-out part in the slider will be retracted to the inside of the slider insert, thereby achieving the purpose of separating the end of the core pull-out part in the slider from the position of the inverted product.
[0035] It is worth mentioning that since the side of the pull-out rod in the slider is connected to the core pull-out part in the slider and is arranged in an inclined surface, the diameter of the end of the pull-out rod in the slider away from the first slider seat is smaller than the end close to the first slider seat, ensuring that the core pull-out part in the slider will shrink toward the inside of the slider insert when it moves along the inclined surface.
[0036] Preferably, a limit block 9 is provided on one side of the second slider seat 3, and a limit surface 10 is provided on the side of the second slider seat 3 close to the limit block 9. When the slider body 1 drives the first slider seat 2 to move, the limit block 9 contacts the limit surface 10. When the slider body 1 drives the second slider seat 3 to move, the limit block 9 moves away from the second slider seat 3.
[0037] Specifically, when the slider body initially drives the first slider seat to move, the second slider seat is restricted by the limit block through the interference between the limit block and the limit surface, so that initially only the first slider seat moves. When the slider body moves a certain distance so that the slider body contacts the limit portion, the limit block moves away from the second slider seat, so that the slider body can now drive the second slider seat to move through the limit portion, thereby avoiding the problem of the second slider seat moving in advance when the first slider seat moves, thereby ensuring the stability of the two-stage sliding core pulling step.
[0038] Preferably, the first slider seat 2 has an oblique contact surface 11 on one side close to the limit block 9 . When the slider body 1 drives the first slider seat 2 to move, the oblique contact surface 11 pushes the limit block 9 to move away from the second slider seat 3 .
[0039] Specifically, when the slider body drives the first slider seat to move, the obliquely inserted contact surface pushes the limit block to move away from the second slider seat, thereby ensuring that when the slider body moves a certain distance so that the slider body contacts the limit portion, the limit block can move away from the second slider seat to ensure that the second slider seat can perform secondary sliding and core pulling normally.
[0040] Among them, the oblique insertion surface is an inclined structure, and the inclined structure pushes the limit block to move.
[0041] Preferably, the side of the limit block 9 away from the second slider seat 3 is connected to the limit seat 12 , the limit block 9 can move relative to the limit seat 12 , and an elastic member is connected between the limit block 9 and the limit seat 12 .
[0042] Specifically, the moving direction of the limit block is limited by the limit seat, and the elastic member increases the elasticity of the limit block so that when the limit block is reset, the elastic member can assist the limit block in rebounding.
[0043] In one embodiment of this solution, the elastic member is a spring.
[0044] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
