[0017] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiment of the utility model is described in detail below with reference to the drawings.
[0018] As Figure 1 , Figure 2As shown in the figure, the embodiment of the application provides an injection mold with replaceable sliders, which comprises a movable mold 1, a fixed mold 2, a first forming assembly 3 arranged on the fixed mold 2, a second forming assembly 4 arranged on the movable mold 1, and a stripping assembly. The first forming assembly 3 comprises a slider part 31, a core-pulling mechanism 32, a sliding seat 33 slidably connected with the core-pulling mechanism 32, a slider body 34 fixedly arranged on the upper end face of the sliding seat 33, and a guide column 35 arranged on the slider body 34. The slider body 34 is provided with a first step, the slider part 31 is provided with a second step corresponding to the first step, and the guide column 35 is arranged on the slider part 31 and protrudes towards the movable mold 1. Figure 4 As shown in the figure, the slider part 31 is provided with an inclined hole 311 for cooperating with the inclined guide column 35, and the upper end face of the slider part 31 is further provided with a placement hole 310 for placing an insert.
[0019] In actual use, before injection preparation, the mold is in an open mold state, the slider part 31 and the slider body 34 are disassembled, the slider part 31 is inserted into the guide column 35 after the insert is placed on the slider part 31 outside the mold, so that the slider part 31 is placed on the slider body 34, and then the mold is closed for injection. After injection is completed, the core-pulling mechanism 32 drives the sliding seat 33 to move obliquely downward, so that the sliding seat 33 drives the slider, the slider body 34 and the slider part 31 to move synchronously, and the separation of the slider part 31 and the insert is completed.
[0020] In the above design, the slider part 31 and the slider body 34 are arranged, the insert is first placed on the slider part 31, and then the slider part 31 is placed on the slider body 34 by using the detachable principle between the slider part 31 and the slider body 34, so that the placement of the insert is more convenient and fast, and the placement precision is higher.
[0021] Specifically, as shown in the figures, Figure 2 and Figure 3 As shown in the figures, the core-pulling mechanism 32 comprises a horizontal rod 321 and an inclined rod 322 arranged on the side of the horizontal rod 321 facing the movable mold 1, the sliding seat 33 is provided with a sliding groove for slidably connecting with the inclined rod 322, the sliding groove has two ends corresponding to the movable mold 1 and the fixed mold 2 respectively, and the movable mold 1 and the fixed mold 2 form a through hole 101 for sliding the sliding seat 33.
[0022] In actual use, the horizontal movement of the core-pulling mechanism 32 makes the inclined rod 322 abut against the inner walls of different positions of the sliding groove, so that the sliding seat 33 moves along the through hole 101.
[0023] In the above design, the structure design of the core-pulling mechanism 32 and the sliding seat 33 facilitates the driving of the sliding seat 33 along the through hole 101.
[0024] Specifically, as shown in the figures, Figure 1 and Figure 2As shown, the through hole 101 is provided with a screw hole on the inner wall of the fixed mold 2 side, and a limiting bolt 5 is threadedly connected to the screw hole, and the bolt 5 is used to prevent the sliding seat 33 from falling along the through hole 101.
[0025] In actual use, when the core pulling part 32 is completely separated from the sliding seat 33, the sliding seat 33 will slide downward along the through hole 101, and at this time, the sliding seat 33 can be limited from falling out of the through hole 101 by the bolt 5.
[0026] In the above design, by arranging the bolt 5 on the inner wall of the through hole 101, the downward sliding of the sliding seat 33 can be effectively limited.
[0027] Specifically, as shown in the drawings, Figure 3 As shown, the first step includes a slope A301, a slope B302 and a slope C303, the slope A301 and the slope C303 are parallel and both are inclined to the fixed mold 2 side, the lower end of the slope B302 is connected to the slope A301 on the fixed mold 2 side, the upper end of the slope B302 is connected to the slope C303 on the movable mold 1 side, the slope A301 and the slope B302 are 90°, the second step includes a slope a which can coincide with the slope A301, a slope b which can coincide with the slope B302 and a slope c which can coincide with the slope C303, and the guide column 35 protrudes the slope B302.
[0028] In actual use, when the sliding block split body 31 coincides with the sliding block body 34, the slope A301 coincides with the slope a, the slope B302 coincides with the slope b, and the slope C303 coincides with the slope c.
[0029] In the above design, the structure design and specific implementation of the first step and the second step facilitate the realization that the sliding block split body 31 will not easily slide after coinciding with the sliding block body 34, and the sliding block split body 31 can be limited by the inclined direction of the slope.
[0030] Specifically, as shown in the drawings, Figure 3 As shown, the axis of the guide column 35 is parallel to the slope A301.
[0031] In the above design, the guide column 35 is parallel to the slope A301, which facilitates the insertion of the sliding block split body 31 along the angle of the slope A301 and the guide column 35.
[0032] It should be understood that the above only describes specific embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
