[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are a type of molding equipment that uses plastic molds to produce various shapes of plastic products from thermoplastic or thermosetting plastics. According to the arrangement of the injection device and the clamping device, injection molding machines can be divided into vertical, horizontal, and vertical-horizontal combination types. Its main function is to transform thermoplastic plastics from granular raw materials into the final molded products, and to complete a cycle of melting, injection, holding pressure and cooling in each step. The advantages of injection molding machines are mainly reflected in high-efficiency production, cost savings and flexibility.

[0003] The problem with existing technology is that when the injection molding machine pours material into the mold, the stability of the mold needs to be determined. If the mold moves, it will affect the pouring effect and thus affect the molding of the item. Utility Model Content

Placement frames are fixedly connected to both the front and rear sides of the two guide frames, and the screw and guide rod are rotatably connected to the surface of the placement frame. A bracket is fixedly connected to the rear side of the base. A motor is fixedly connected to the top of the device. The output end of the motor is fixedly connected to a screw that is rotatably connected to the surface of the left-side placement frame. Two sleeve blocks are threadedly connected to the surface of the screw, and two sliding blocks are sleeved on the surface of the bare rod. A clamping plate is provided on the side of the sleeve blocks and sliding blocks that are close to each other.

A cavity is provided inside the sleeve blocks and sliding blocks. A positioning mechanism is provided inside the cavity, and an adjustment mechanism that works in conjunction with the positioning mechanism is provided inside the cavity.

[0006] In a preferred embodiment of this invention, the positioning mechanism includes two connecting blocks, two insert rods, two tension springs, and two connecting posts. The two insert rods are respectively fixedly connected to the two connecting blocks on opposite sides, with the insert rods extending through and into the insertion hole on the side closest to the clamping plate.

[0015] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0016] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figures 1 to 4As shown in the figure, an auxiliary mechanism for an injection molding machine provided by this utility model includes a base 1, a placement platform 2, and an injection frame 3. The placement platform 2 is fixedly connected to the top of the base 1, and the injection frame 3 is fixedly connected to the top of the placement platform 2. Guide frames 4 are fixedly connected to the left and right sides of the top of the placement platform 2. A screw 5 is rotatably connected inside the left guide frame 4, and a smooth rod 6 is rotatably connected inside the right guide frame 4. Placement frames 7 are fixedly connected to the front and rear sides of both guide frames 4, and the screw 5 and the smooth rod 6 are rotatably connected to the surface of the placement frame 7. A bracket 8 is fixedly connected to the rear side of the base 1, and a [missing information - likely a component or component] is fixedly connected to the top of the bracket 8. The output end of the motor 9 is fixedly connected to the screw 5 that is rotatably connected to the surface of the left placement frame 7. The surface of the screw 5 is threaded with two sleeve blocks 10, and the surface of the smooth rod 6 is fitted with two sliding blocks 11. A clamping plate 12 is provided on the side of the sleeve block 10 and the sliding block 11 that are close to each other. The left and right sides of the surface of the clamping plate 12 have notches, and the top and bottom of the inner wall of the notch are provided with insertion holes 13. The inside of the sleeve block 10 and the sliding block 11 are both provided with cavities 14. A positioning mechanism 15 is provided inside the cavity 14, and an adjustment mechanism 16 that works in conjunction with the positioning mechanism 15 is provided inside the cavity 14.

[0018] refer to Figure 3 and Figure 4 The positioning mechanism 15 includes two connecting blocks 1501, two insert rods 1502, two tension springs 1503, and two connecting posts 1504. The two insert rods 1502 are respectively fixedly connected to the two connecting blocks 1501 on opposite sides. The side of the insert rod 1502 closest to the clamping plate 12 passes through and extends into the interior of the insertion hole 13. The two tension springs 1503 are respectively sleeved on the surface of the two insert rods 1502. The two ends of the tension springs 1503 are respectively fixedly connected to the surface of the connecting block 1501 and the inner wall of the cavity 14. The two connecting posts 1504 are respectively fixedly connected to the front side of the two connecting blocks 1501. Both connecting posts 1504 are used in conjunction with the adjustment mechanism 16.

[0019] Using the above solution: by setting the positioning mechanism 15, the clamping plate 12 can be fixed by the sleeve block 10 and the sliding block 11, so that the mold during injection can be clamped by the clamping plate 12.

[0020] refer to Figure 4The adjusting mechanism 16 includes a pull rod 1601, two push columns 1602, two cylinders 1603, and two connecting rods 1604. The two push columns 1602 are fixedly connected to the rear side of the pull rod 1601. The front side of the pull rod 1601 passes through and extends out of the surface of the sleeve block 10 or the sliding block 11. The two cylinders 1603 are fixedly connected to the inner wall of the cavity 14. The two connecting rods 1604 are rotatably connected to the surface of the two cylinders 1603. The rear side of the two push columns 1602 passes through the surface of the two connecting rods 1604. The side of the two connecting rods 1604 closest to the two connecting columns 1604 is sleeved on the surface of the connecting column 1604.

[0021] By adopting the above solution, the clamping plate 12 can be disassembled and replaced by setting the adjustment mechanism 16, so that different clamping plates 12 can be selected for use.

[0022] refer to Figure 4 The connecting rod 1604 has a transmission hole 17 on its surface, and the inner wall of the transmission hole 17 is in contact with the surface of the push column 1602.

[0023] By adopting the above solution: by opening the transmission hole 17, the inner wall of the transmission hole 17 can be squeezed by the pushing column 1602, thereby causing the connecting rod 1604 to rotate around the cylinder 1603.

[0024] refer to Figure 4 Limiting rods 18 are provided on both the left and right sides of the two connecting blocks 1501. The top and bottom of the two limiting rods 18 are fixedly connected to the inner wall of the cavity 14, and the two connecting blocks 1501 are slidably connected to the surface of the two limiting rods 18.

[0025] By adopting the above solution, the movement of the connecting block 1501 can be restricted by setting the limiting rod 18, so as to prevent the connecting block 1501 from deviating or tilting when moving.

[0026] refer to Figure 3 The threads on both sides of the screw 5 are set in opposite directions, and the middle part of the screw 5 is a smooth surface.

[0027] By adopting the above solution, by setting threads in opposite directions, the two clamping plates 12 can be moved relative to each other or away from each other, thereby clamping or loosening the mold.

[0028] The working principle of this utility model: In use, the motor 9 is started, which drives the screw 5 to rotate. As the screw 5 rotates, it moves the two sleeve blocks 10 on its surface closer together. The movement of the sleeve blocks 10 moves the clamping plate 12, which in turn moves the sliding block 11 along the surface of the smooth rod 6. This allows the two clamping plates 12 to move closer or further apart, thus clamping or releasing the injection mold. When the clamping plate 12 needs to be replaced, the pull rod 1601 is moved closer to the clamping plate 12. The pull rod 1601 moves the two push columns 1602, causing them to move. 02 During movement, the inner wall of the transmission hole 17 is squeezed, causing both connecting rods 1604 to rotate around the surfaces of the two cylinders 1603. After the two connecting rods 1604 move, they squeeze the surface of the connecting column 1504 through the inner wall of the transmission hole 17, thereby driving the two connecting columns 1504 to move towards each other. Then, the movement of the connecting column 1504 drives the connecting block 1501 to move. Then, the movement of the connecting block 1501 drives the insert rod 1502 away from the insert hole 13 and stretches the tension spring 1503. At this time, the clamping plate 12 can be replaced, and a suitable clamping plate 12 can be selected to clamp the mold.

[0029] In summary, the auxiliary mechanism for this injection molding machine, through the coordinated use of a base 1, a placement platform 2, an injection frame 3, a guide frame 4, a screw 5, a guide rod 6, a placement frame 7, a support 8, a motor 9, a socket block 10, a sliding block 11, a clamping plate 12, an insertion hole 13, a cavity 14, a positioning mechanism 15, a connecting block 1501, an insertion rod 1502, a tension spring 1503, a connecting column 1504, an adjusting mechanism 16, a pulling rod 1601, a pushing column 1602, a cylinder 1603, a connecting rod 1604, a transmission hole 17, and a limiting rod 18, solves the problem of ensuring mold stability when the injection molding machine pours material into the mold. Mold movement affects the pouring effect and thus the molding of the product.
