[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 As shown, a mold frame guide mechanism for automobile parts production includes a base 1, on which a fixed plate 2 for supporting a fixed mold, a movable plate 3 for supporting a moving mold, and a driver 4 are mounted. The fixed plate 2 and the movable plate 3 are arranged opposite to each other, and the distance between the fixed plate 2 and the movable plate 3 is adjusted by the driver 4.

[0026] A guide post 5 is installed on the side of the fixed plate 2 near the movable plate 3. A guide hole 6 that is adapted to and corresponds to the guide post 5 is opened on the side of the movable plate 3 near the fixed plate 2. A buffer component is installed in the guide hole 6. When the movable plate 3 moves and approaches the fixed plate 2, the moving mold and the fixed mold begin to close. The free end of the guide post 5 is inserted into the guide hole 6 and buffered by the buffer component.

[0027] The side of the fixed plate 2 close to the movable plate 3 is flush with the end face of the fixed die, the side of the movable plate 3 close to the fixed plate 2 is flush with the end face of the movable die, and the length of the guide column 5 is consistent with the length of the guide column on the end face of the fixed plate 2. When the driver 4 drives the movable plate 3 to close to the fixed plate 2 and the movable die starts to close with the fixed die, the guide column on the fixed die is inserted into the guide sleeve on the movable die, at the same time, the guide column 5 is inserted into the guide hole 6. With the continuous closing operation, the guide column 5 contacts the buffer assembly and buffers the closing impact force to improve the closing stability. When the guide column 5 is completely inserted into the guide hole 6, the fixed plate 2 contacts the movable plate 3, the end faces of the fixed die and the movable die are attached, and the closing is completed.

[0028] Specifically, as shown in Figure 3 and Figure 4 , the buffer assembly includes a guide rod 7, a sliding block 8 and a spring 9. One end of the guide rod 7 is installed on the side wall of the guide hole 6 away from the opening, the other end of the guide rod 7 extends to the opening of the guide hole 6 and is coaxially centered, the sliding block 8 and the spring 9 are sleeved on the guide rod 7, the sliding block 8 is sleeved on the end of the guide rod 7 close to the opening of the guide hole 6, one end of the spring 9 is fixedly connected with the side wall of the guide hole 6 away from the opening, and the other end of the spring 9 is fixedly connected with one side end face of the sliding block 8.

[0029] When the free end of the guide column 5 is inserted into the opening of the guide hole 6, the guide column 5 is sleeved on the guide rod 7, and the free end of the guide column 5 contacts the sliding block 8. With the continuous insertion of the guide column 5, the guide column 5 pushes the sliding block 8 to slide along the guide rod 7 to the depth of the guide hole 6, and the sliding block 8 extrudes the spring 9, which utilizes the elastic deformation of the spring 9 to buffer the closing impact force. This not only improves the closing stability and closing precision, but also plays a certain mold protection role.

[0030] Further, as shown in Figure 4 , the sliding block 8 is a circular ring and consistent with the outer diameter of the guide column 5, the guide rod 7 is sleeved on the inner wall of the guide column 5, and the outer wall of the sliding block 8 is slidably connected with the inner wall of the guide hole 6, which can improve the insertion stability of the guide column 5 and the guide hole 6, and improve the buffering effect of the buffer assembly on the closing impact force.

[0031] Further, as shown in Figure 4 , the first buffer ring 10 is installed on the side end face of the sliding block 8 away from the spring 9, and the second buffer ring 11 is installed on the free end of the guide column 5. When the free end of the guide column 5 is inserted into the guide hole 6 and contacts the sliding block 8, the second buffer ring 11 is tightly attached to the first buffer ring 10. The first buffer ring 10 and the second buffer ring 11 are both rubber rings or silica gel rings, which can improve the actual buffering effect.

[0032] Specifically, asFigure 1 As shown in the drawings, the fixed plate 2 is fixedly installed on one side of the upper end face of the base 1, and the movable plate 3 is slidably installed on the other side of the upper end face of the base 1, and the movable plate 3 is connected with the movable end of the driver 4, and the movable plate 3 is driven by the driver 4 to move close to or away from the fixed plate 2;

[0033] Further, as shown in the drawings, Figure 2 The upper end faces of the fixed plate 2 and the movable plate 3 are both provided with a pad plate 12 for bearing the mold body, and the upper end faces of the fixed plate 2 and the movable plate 3 are both provided with a slot 13 matched with the mold bottom plate, and the two slots 13 are respectively arranged on the sides of the two pad plates 12 away from each other, and the mold bottom plate is inserted into the slot 13 and fixed by a fastener;

[0034] It should be noted that the mold here is a traditional injection mold commonly used in the production of automobile parts, as shown in the drawings, Figure 1 The mold body of the injection mold has a mold bottom plate on one side, and the area of the mold bottom plate is larger than that of the mold body, so that a step is formed between the mold body and the mold bottom plate, and the mold body is supported by the pad plate 12, and the protruding mold bottom plate is inserted into the slot 13, so that the injection mold can be quickly installed on the fixed plate 2 and the movable plate 3, and then the mold can be fixed by a fastener, which is convenient for adding various molds.

[0035] Specifically, as shown in the drawings, Figure 2 The driver 4 includes a motor, a lead screw and a sliding block, the motor is installed on one side of the base 1, the upper end face of the base 1 is provided with a sliding groove arranged along the length direction thereof, the lead screw is rotatably installed in the sliding groove and is driven to rotate by the motor, and the sliding block is slidably arranged in the sliding groove, one end of the sliding block is rotatably connected with the lead screw, and the other end of the sliding block extends upward and is fixedly connected with the bottom of the movable plate 3. The driver 4 can also adopt a cylinder, an electric cylinder or other motor combination structure in the prior art.

[0036] In summary, by installing the fixed plate 2 and the movable plate 3 on the base 1 in opposite arrangement, the distance between the fixed plate 2 and the movable plate 3 is adjusted by the driver 4, so that the movable plate 3 drives the movable die on it to perform the mold closing operation with the fixed die on the fixed plate 2, and the precise guidance between the fixed plate 2 and the movable plate 3 is realized by the insertion of the guide column 5 and the guide hole 6, thereby improving the guidance accuracy of the mold frame and the mold. The actual buffering effect can be improved by buffering the impact force of the insertion of the guide column 5 and the guide hole 6 by the buffering assembly, thereby improving the mold closing stability and accuracy, and without the need to modify the mold frame body, only the installation of the guide mechanism is needed, which is suitable for the guidance of various molds and has a broad market prospect.

[0037] Any technical features in the above embodiments can be combined (as long as the combination of the technical features does not cause contradiction), and for the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; the embodiments not explicitly written in the above description should also be considered as the scope of the present disclosure.
