[0030] An injection molding machine mold clamping device that is convenient for adjustment, the structure of which can be Figures 1 - 6A schematic illustration is provided. In this embodiment, the injection molding machine mold clamping device that is easy to adjust includes: a bottom plate 1, a base 2, and a pressing assembly. The bottom plate 1 is used to achieve the assembly between this device and the clamping plate of the injection molding machine. The pressing assembly is used to press and fix the mold. The base 2 is used to carry the pressing assembly, facilitating the sliding of the pressing assembly and flexibly adjusting the angle of the pressing assembly so that this device can meet different usage requirements.

[0031] Specifically, in this embodiment, the base 2 is arranged on the top of the bottom plate 1, and the pressing assembly is arranged on the base 2. To achieve the sliding function of the pressing assembly, as Figure 4 and Figure 6 shown, a receiving groove 22 is provided on the top surface of the base 2. The pressing assembly includes a connecting arm 4, and detachable pressing heads are respectively arranged at both ends of the connecting arm 4. During assembly, the staff can arrange the connecting arm 4 inside the receiving groove 22 so that the connecting arm 4 can slide along the length direction of the receiving groove 22, thereby facilitating the adjustment of the position of the pressing head through the sliding of the connecting arm 4 during actual use. Correspondingly, to achieve the angle adjustment function of the pressing assembly, as Figure 3 and Figure 5 shown, a positioning hole 11 and an arc-shaped notch 12 are provided on the bottom plate 1. The center of the arc of the arc-shaped notch 12 coincides with the center of the circle of the positioning hole 11, and a positioning shaft 21 is provided on the bottom surface of the base 2. During assembly, the staff can rotatably insert the positioning shaft 21 into the positioning hole 11 so that the base 2 can rotate around the positioning shaft 21 during actual use, thereby facilitating the adjustment of the angle of the pressing assembly.

[0032] To prevent abnormal movement of the connecting arm 4 and the base 2 during the use of this device, the pressing assembly further includes a pressing bolt 5. A first receiving hole 23 and a second receiving hole 24 are provided inside the receiving groove 22, and the first receiving hole 23 and the positioning shaft 21 are respectively located at both ends of the second receiving hole 24. A positioning bolt 3 is provided inside the first receiving hole 23. The head of the positioning bolt 3 is slidably arranged inside the arc-shaped notch 12, and a positioning sleeve 31 is provided on the positioning bolt 3. The head of the pressing bolt 5 is placed inside the second receiving hole 24, and a pressing sleeve 51 is provided on the pressing bolt 5. Correspondingly, an avoidance oblong hole 41 for receiving the pressing bolt 5 and the positioning sleeve 31 should be provided on the connecting arm 4, and the length direction of the avoidance oblong hole 41 is parallel to the sliding direction of the connecting arm 4.

[0033] After completing the angle adjustment of the pressing assembly by rotating the base 2, the staff can tighten the positioning sleeve 31 so that the bottom end of the positioning sleeve 31 abuts against the bottom of the receiving groove 22, thereby restricting the continued rotation of the base 2. After completing the position adjustment of the pressing head by sliding the connecting arm 4, the staff can tighten the pressing sleeve 51 so that the bottom end of the pressing sleeve 51 abuts against the top surface of the connecting arm 4, thereby restricting the continued sliding of the connecting arm 4.

[0034] Optionally, to enhance the rotational restraint effect of the base 2, positioning protrusions 25 may be provided on the bottom surface of the base 2, and a plurality of positioning grooves 13 for accommodating the positioning protrusions 25 are provided on the top surface of the base plate 1, and the plurality of positioning grooves 13 are uniformly arranged along the length direction of the arc-shaped notch 12. After the staff tightens the positioning sleeve 31, the positioning protrusion 25 will be inserted into a certain positioning groove 13, thereby improving the limiting strength of the base 2.

[0035] In addition, to enhance the sliding restraint effect of the connecting arm 4, the pressing assembly in this embodiment may further include a locking piece 7. As Figure 6 shown, the locking piece 7 should be located between the pressing sleeve 51 and the connecting arm 4, and a locking hole 71 for accommodating the pressing bolt 5 is provided on the locking piece 7.

[0039] Optionally, to improve the pressing and fixing effect of the pressing head on different areas of the mold, the pressing head may include a first pressing head 61 and a second pressing head 62. As Figure 1 and Figure 2 shown, in this embodiment, the first pressing head 61 and the second pressing head 62 are respectively located at both ends of the connecting arm 4, and a V-shaped notch 621 is provided at one end of the second pressing head 62 away from the connecting arm 4. When it is necessary to press and fix the straight-edge area of the mold through this device, the staff can select the first pressing head 61 to participate in the pressing and fixing work, so as to obtain the largest possible contact area between this device and the mold. When it is necessary to press and fix the arc area or corner area of the mold through this device, the staff can select the second pressing head 62 to participate in the pressing and fixing work, so as to accommodate the arc part or corner part of the mold by means of the V-shaped groove 621 and ensure good fixing effect of the mold.

[0040] As an optional implementation manner of this embodiment, to facilitate the assembly between this device and the injection molding machine, mounting holes 14 may be provided on the bottom plate 1, and mounting bolts 8 are provided inside the mounting holes 14. During use, the staff can first select the installation position of this device on the clamping plate of the injection molding machine according to the use requirements, and then screw the mounting bolts 8 into the preset mounting screw holes on the clamping plate of the injection molding machine, so as to fix this device on the injection molding machine.
