Description

Technical Field

[0001] The utility model relates to the technical field of mold slide rails, in particular to a limiting device for preventing a sliding block from sliding out. Background Art

[0002] A mold is a tool used to shape objects. This tool is made up of various parts, and different molds are made up of different parts.

[0003] During the production process of mold products, a slider needs to be installed on the rear template. The slider facilitates the molding of the mold product on the rear template. However, the slider is easy to slide out of the slide rail, thereby affecting the molding of the mold.

[0004] For example, on March 1, 2017, a patent with the publication number CN103453015A was published, entitled "A Ultra-Long Distance Guide Slide", which includes a slider portion and a slide rail portion; the slide rail portion is formed by longitudinally splicing slide rail modules; the slide rail module is formed by transversely splicing two identical profiles with rectangular cross-sections and T-slots on all four sides; adjacent slide rail modules are respectively installed with inlays in the T-slots on the upper and lower surfaces, and the inlays and connecting plates are connected by screws. This invention realizes ultra-long distance linear motion guidance and has a strong load-bearing capacity; however, in the above documents, the component used to prevent the slider from sliding is an inlay fixed on the template. The fixed inlay is difficult to disassemble after being damaged, and even the entire mold needs to be replaced, which increases the mold cost. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a limiting device for preventing a slider from sliding out, so as to solve the problem of high mold cost.

[0006] Based on the above-mentioned purpose, the utility model provides a limiting device to prevent the sliding block from sliding out, including a guide slide rail opened on the mold body, a guide slide rail slidingly connected to the guide slide rail, and a limiting structure for preventing the guide slide rail from sliding out of the guide slide rail is provided on the guide slide rail. The limiting structure includes a frame mounted outside the mold body and two limiting parts respectively located at both ends of the guide slide rail, the limiting part includes a limiting baffle connected to the inner inner wall of the frame, and the limiting baffle is located inside the guide slide rail.

[0007] Optionally, an elastic pad is provided on the side of the limiting baffle facing the guide slider.

[0008] Optionally, the limiting baffle is connected to the inner side wall of the frame via a connecting rod, and a rubber pad is fixedly connected between the connecting rod and the frame.

[0009] Optionally, the limiting member also includes a slip-limiting screw arranged on the guide rail, the slip-limiting screw includes a screw rod and a screw head fixed to the upper end of the screw rod, the bottom surface of the guide rail is provided with a screw hole arranged to cooperate with the screw rod, and the screw rod extends into the screw hole.

[0010] Optionally, an elastic head cover is provided on the outer side of the screw head.

[0011] Optionally, the lower end surface of the elastic head cover is in contact with a friction plate arranged on the bottom surface of the guide rail.

[0012] Optionally, a limiting rail slidably connected to the frame is provided on the side of the mold body, and the limiting rail is arranged parallel to the guide rail.

[0013] The beneficial effects of the present invention: The present invention provides a limiting device to prevent the sliding block from sliding out, a frame is sleeved on the outside of the mold body, and two limiting baffles connected in the frame are located at both ends of the guide slide rail. When the guide slider slides toward the two ends of the guide slide rail, the limiting baffle can limit the guide slider from sliding out of the guide slide rail to prevent the guide slider from being damaged. The horizontal impact of the guide slider moving is different from the vertical force direction of the frame moving out of the mold body, so that when the guide slider impacts the limiting baffle and the frame, the frame is not easy to separate from the mold body, which greatly increases the safety of use. In addition, the frame can be used repeatedly, thereby reducing the production cost of the mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a limiting device to prevent a sliding block from sliding out comprises a guide rail 1 provided on a mold body 3, a guide slider 2 being slidably connected inside the guide rail 1, and a limiting structure for preventing the guide slider 2 from sliding out of the guide rail 1 being provided on the guide rail 1, the limiting structure comprising a frame 8 sleeved outside the mold body 3 and two limiting members 4 respectively located at both ends of the guide rail 1, the limiting member 4 comprising a limiting baffle 6 connected to the inner side wall of the frame 8, and the limiting baffle 6 is located inside the guide rail 1.

[0023] When it is necessary to limit the guide slider 2 from sliding out from the two ends of the guide slide rail 1, the frame 8 is sleeved on the outside of the mold body 3, and the two limiting baffles 6 connected in the frame 8 are at the two ends of the guide slide rail 1. When the guide slider 2 slides toward the two ends of the guide slide rail 1, the limiting baffle 6 can limit the guide slider 2 from sliding out of the guide slide rail 1 to prevent the guide slider 2 from being damaged. The horizontal impact of the guide slider 2 moving is different from the vertical force direction of the frame moving out of the mold body 3, so that when the guide slider 2 impacts the limiting baffle 6 and the frame 8, the frame 8 is not easy to separate from the mold body 3, which greatly increases the safety of use. In addition, the frame 8 can be used repeatedly, thereby reducing the mold production cost.

[0024] There are two guide sliders 2, and the two guide sliders 2 are located between the two limiting members 4. When the two guide sliders 2 move in opposite directions, the two limiting members 4 respectively limit the movement of the two guide sliders 2 to prevent the two guide sliders 2 from sliding out of the guide rail 1.

[0025] An elastic pad 7 is provided on the side of the limiting baffle 6 that is opposite to the guide slider 2. The material of the elastic pad 7 can be rubber. The setting of the elastic pad 7 is convenient for reducing the impact of the guide slider 2 on the limiting baffle 6, while avoiding rigid collision between the guide slider 2 and the limiting baffle 6 to reduce damage.

[0026] The limiting baffle 6 is connected to the inner side wall of the frame 8 via a connecting rod. A rubber pad is fixedly connected between the connecting rod and the frame 8 to reduce the impact of the guide slider 2 on the frame 8.

[0027] The limiting member 4 also includes a limited-slip screw 5 arranged on the guide slide rail 1. The limited-slip screw 5 includes a screw rod and a screw head fixed to the upper end of the screw rod. The bottom surface of the guide slide rail 1 is provided with a screw hole that cooperates with the screw rod. The screw rod extends into the screw hole. The setting of the limited-slip screw 5 is convenient for preventing the guide slider 2 from sliding out of the guide slide rail 1. In addition, the screw rod is completely extended into the screw hole, so that the force point of the guide slider 2 hitting is on the screw head, which changes the force point of the limited-slip screw 5 and ensures the life of the limited-slip screw 5.

[0028] An elastic head cover is provided on the outer side of the screw head, which is convenient for protecting the screw head on one hand and for reducing the impact force of the guide slider 2 impacting the screw head on the other hand.

[0029] The lower end surface of the elastic head cover is in contact with a friction plate arranged on the bottom surface of the guide slide rail 1. The friction plate and the elastic head cover are in friction cooperation, which reduces the possibility of the guide slider 2 hitting the screw head and causing the elastic head cover to rotate, thereby reducing the possibility of the limited slip screw 5 rising. The screw rod of the limited slip screw 5 sinks directly into the screw hole, so that the force point of the guide slider 2 hitting is on the screw head. On the one hand, it solves the problem of frequent breakage of the limited slip screw 5, and secondly, it does not increase the cost, thereby improving stability and affordability.

[0030] The side of the mold body 3 is provided with a limiting rail slidably connected to the frame 8 . The limiting rail is arranged parallel to the guide rail 1 to facilitate limiting the left and right movement of the frame 8 and prevent the frame 8 from leaving the mold body 3 .
