Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of positioning adjustment device of injection molding machine intermediate connecting seat. BACKGROUND

[0002] Currently, the injection molding machine's shooting platform and base generally need to be connected by intermediate connecting seat, that is, the intermediate connecting seat is fixed on the base, and the shooting platform is installed on the intermediate connecting seat. The common solution is to weld the intermediate connecting seat directly to the base, and then detachably install the shooting platform on the intermediate connecting seat. However, since the intermediate connecting seat is welded to the base, the shooting platform cannot be adjusted after being installed on the intermediate connecting seat, resulting in that the centering degree of the shooting nozzle of the shooting platform completely depends on the positioning accuracy between the intermediate connecting seat and the base. In addition, since the intermediate connecting seat is welded to the base, when replacing the shooting platform, the new shooting platform must match the installation structure of the intermediate connecting seat. However, in order to better match the production efficiency, the injection molding machine often needs to use shooting platforms of different sizes according to production needs, which limits the selection of the shooting platform and is not conducive to the disassembly and exchange of large and small shooting platforms.

[0003] Therefore, how to overcome the above-mentioned defects has become an important issue for technicians in the field to solve. CONTENT OF THE UTILITY MODEL

The intermediate connecting seat 3 is placed on the placement platform. Each support block 2 is connected with the intermediate connecting seat 3 by a height adjustment assembly 4. The height adjustment assembly 4 is used to fix and change the vertical gap between the intermediate connecting seat 3 and the corresponding support block 2, so as to adjust the height of the intermediate connecting seat 3. The four support blocks 2 at the front and back ends are each provided with a centering adjustment assembly 5 between the intermediate connecting seat 3. The centering adjustment assembly 5 is used to adjust the distance between the outer edge of the intermediate connecting seat 3 and the outer edge of the corresponding support block 2.

[0007] Preferably, the height adjusting assembly 4 comprises a first threaded through hole 41 vertically arranged on the intermediate connecting base 3, the first threaded through hole 41 is located above the corresponding support block 2 of the height adjusting assembly 4, a height adjusting bolt 42 is threadedly connected in the first threaded through hole 41, the lower end of the height adjusting bolt 42 extends out of the bottom surface of the intermediate connecting base 3 and abuts against the corresponding support block 2 as the height adjusting bolt 42 is tightened, and the height adjusting assembly 4 further comprises a locking module arranged between the height adjusting bolt 42 and the corresponding support block 2, the locking module is used for locking the intermediate connecting base 3 on the support block 2 to avoid the intermediate connecting base 3 from being separated from the base 1.

[0009] Preferably, the diameter of the third through hole 44 is D, the nominal diameter of the locking bolt 45 is d, and 1.2d≤D≤1.3d.

[0010] Preferably, a flat medium 46 is further sleeved on the locking bolt 45 between the third through hole 44 and the head of the locking bolt 45, and a spring washer 47 is arranged between the head of the locking bolt 45 and the flat medium 46.

[0011] Preferably, the centering adjusting assembly 5 comprises a transverse limiting block 51 fixedly arranged on the support block 2 and extending upwards, the transverse limiting block 51 is arranged on the side of the corresponding support block 2 away from the intermediate connecting base 3, a fourth threaded through hole 52 is horizontally arranged on the transverse limiting block 51, a centering adjusting bolt 53 is threadedly connected in the fourth threaded through hole 52, the centering adjusting bolt 53 is screwed into the fourth threaded through hole 52 from the direction of the intermediate connecting base 3 outside the intermediate connecting base 3, and the end of the centering adjusting bolt 53 abuts against the side wall of the intermediate connecting base 3, and the end of the centering adjusting bolt 53 pushes the corresponding angular position of the intermediate connecting base 3 away from the transverse limiting block 51 as the centering adjusting bolt 53 is tightened.

[0012] Preferably, the left and right sides of the bottom of the intermediate connecting base 3 are provided with connecting portions 31 extending outward, and the height adjusting assembly 4 and the centering adjusting assembly 5 are connected at the connecting portions 31.

This allows for adjustment and fixation of the intermediate connecting seat's vertical and horizontal positions. Thus, after the injection unit is installed on the intermediate connecting seat, the vertical, horizontal, and centering of the injection unit can be indirectly adjusted via the height and centering adjustment components, significantly reducing the precision requirements for the intermediate connecting seat's installation. Furthermore, since the intermediate connecting seat is not welded to the base, when different injection units need to be replaced, if the installation structure of the intermediate connecting seat is incompatible with the installation structure of the injection unit, the base can be easily replaced to achieve compatibility with different injection units, thereby greatly expanding the applicability of the injection molding machine.

[0020] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0021] like Figures 1 to 5 As shown, a positioning and adjustment device for an injection molding machine intermediate connecting seat includes eight support blocks 2 fixed on a base 1 of the injection molding machine. The support blocks 2 are symmetrically and evenly distributed on both sides of the base 1. There are four support blocks 2 evenly distributed front and back on each side of the base 1. The upper surfaces of all the support blocks 2 together form a placement platform. The intermediate connecting seat 3 is placed on the placement platform. Each support block 2 is connected to the intermediate connecting seat 3 with a height adjustment component 4. The height adjustment component 4 is used to fix and change the vertical gap between the intermediate connecting seat 3 and the corresponding support block 2 in order to adjust the height of the intermediate connecting seat 3. The four support blocks 2 at the front and rear ends are respectively provided with a centering adjustment component 5 between them and the intermediate connecting seat 3. The centering adjustment component 5 is used to adjust the distance between the outer edge of the intermediate connecting seat 3 and the outer edge of the corresponding support block 2.

[0022] Different from the traditional fixing mode of directly welding the intermediate connector 3 to the base 1, the intermediate connector positioning and adjusting device in the case sets eight supporting blocks 2 on the base 1, the upper surfaces of all the supporting blocks 2 jointly form a placing platform, and the intermediate connector 3 in the case is placed on the placing platform. Height adjusting assemblies 4 are respectively arranged between each supporting block 2 and the intermediate connector 3, the up-down gap between the intermediate connector 3 and the corresponding supporting block 2 can be fixed and changed through the height adjusting assemblies 4, so that the height position of the intermediate connector 3 can be adjusted by changing the height of the eight point positions of the intermediate connector 3, thereby facilitating the up-down centering of the shooting platform, and the leveling of the intermediate connector 3 can also be realized by changing the height of the individual point positions in a targeted manner, and the locking effect of the intermediate connector 3 on the base 1 can also be realized by fixing the up-down gap between the intermediate connector 3 and the supporting block 2 through the height adjusting assemblies 4 after adjusting the height. In addition, the supporting blocks 2 and the intermediate connector 3 at the four corner positions are also respectively connected with centering adjusting assemblies 5, the distance between the outer edges of the intermediate connector 3 and the corresponding supporting blocks 2 can be adjusted through the centering adjusting assemblies 5, so that the left-right positions of the four corner positions of the intermediate connector 3 can be respectively adjusted through the four centering adjusting assemblies 5, thereby realizing the adjustment of the left-right positions of the intermediate connector 3.

[0023] As described above, the intermediate connector 3 in the case is placed on the supporting blocks 2 on the base 1, and is connected with the supporting blocks 2 through the height adjusting assemblies 4 and the centering adjusting assemblies 5 respectively, thereby realizing the adjustment and fixation of the up-down and left-right positions of the intermediate connector 3, so that after the shooting platform is installed on the intermediate connector 3, the up-down and left-right centering of the shooting platform can be indirectly adjusted through the height adjusting assemblies 4 and the centering adjusting assemblies 5, thereby greatly reducing the requirement for the installation precision of the intermediate connector 3. In addition, since the intermediate connector 3 is not welded and fixed on the base 1, when different shooting platforms need to be replaced, if the installation structure of the intermediate connector 3 does not match the installation structure of the shooting platform, the compatibility of the base 1 to different shooting platforms can also be easily realized by replacing the intermediate connector 3, thereby greatly improving the application range of the injection molding machine.

[0024] Specifically, the height adjusting assemblies 4 and the centering adjusting assemblies 5 both realize the adjusting function through mechanical structures without electricity.

[0025] As Figures 1 to 5As shown, preferably, the height adjusting assembly 4 comprises a first threaded through hole 41 vertically arranged on the intermediate connecting seat 3, the first threaded through hole 41 is above the corresponding support block 2 of the height adjusting assembly 4, a height adjusting bolt 42 is threadedly connected in the first threaded through hole 41, the lower end of the height adjusting bolt 42 extends out of the bottom surface of the intermediate connecting seat 3 and abuts against the corresponding support block 2 as the height adjusting bolt 42 is tightened, the height adjusting assembly 4 further comprises a locking module arranged between the height adjusting bolt 42 and the corresponding support block 2, the locking module is used to lock the intermediate connecting seat 3 on the support block 2 to avoid the intermediate connecting seat 3 from being separated from the base 1.

[0026] As described above, the height adjusting assembly 4 of the present case comprises a first threaded through hole 41 arranged on the intermediate connecting seat 3 above the corresponding support block 2, and a height adjusting bolt 42 is threadedly connected in the first threaded through hole 41, in this way, by tightening the height adjusting bolt 42, the height adjusting bolt 42 can extend downward out of the bottom surface of the intermediate connecting seat 3, and the lower end of the height adjusting bolt 42 abuts against the support block 2 below to support the intermediate connecting seat 3, thus by adjusting the tightness of the height adjusting bolt 42, the gap between the intermediate connecting seat 3 and the corresponding support block 2 can be changed, and in turn the height of the intermediate connecting seat 3 can be changed. Moreover, a locking module is arranged between the height adjusting bolt 42 and the corresponding support block 2, when the height adjustment is completed, the locking module can be used to lock the intermediate connecting seat 3 on the support block 2 to avoid the intermediate connecting seat 3 from being separated from the placing platform upwardly.

[0027] As Figures 1 to 5 shown, preferably, the locking module comprises a second threaded hole 43 arranged on the corresponding support block 2, the height adjusting bolt 42 is provided with a third through hole 44 extending along the axis thereof, the locking module further comprises a locking bolt 45 passing through the third through hole 44 and threadedly connected with the corresponding second threaded hole 43, the diameter of the head of the locking bolt 45 is greater than the diameter of the third through hole 44.

[0028] As described above, the locking module of the present case comprises a third through hole 44 arranged in the height adjusting bolt 42, a second threaded hole 43 arranged on the corresponding support block 2, and a locking bolt 45, the locking bolt 45 is screwed into the second threaded hole 43 after passing through the third through hole 44, and the diameter of the head of the locking bolt 45 is greater than the diameter of the third through hole 44, in this way, after the height is adjusted by rotating the height adjusting bolt 42, the locking bolt 45 can be tightened to press the height adjusting bolt 42 on the support block 2, thereby achieving the locking of the intermediate connecting seat 3.

[0029] As Figures 1 to 5As shown, preferably, the diameter of the third through hole 44 is D, and the nominal diameter of the locking bolt 45 is d, and 1.2d≤D≤1.3d. Thus, setting the diameter of the third through hole 44 to 1.2 to 1.3 times the nominal diameter of the locking bolt 45 can prevent the locking bolt 45 from being damaged or failing due to lateral compression between the locking bolt 45 and the height adjustment bolt 42 when the centering adjustment component 5 adjusts the left and right positions of the intermediate connecting seat 3.

[0030] like Figures 1 to 5 As shown, preferably, the locking bolt 45 is further fitted with a flat section 46 located between the third through hole 44 and the head of the locking bolt 45. A spring washer 47 is provided between the head of the locking bolt 45 and the flat section 46. In this way, by providing the flat section 46, the contact area between the locking bolt 45 and the height adjusting bolt 42 can be increased, while the spring washer 47 can prevent the height adjusting bolt 42 and the locking bolt 45 from loosening.

[0031] like Figures 1 to 5 As shown, preferably, the centering adjustment component 5 includes a lateral limiting block 51 fixedly mounted on the support block 2 and extending upward. The lateral limiting block 51 is located on the side of the support block 2 that is away from the intermediate connecting seat 3. A fourth threaded through hole 52 is horizontally provided on the lateral limiting block 51. A centering adjustment bolt 53 is threadedly connected to the fourth threaded through hole 52. The centering adjustment bolt 53 is screwed into the fourth threaded through hole 52 from the outside of the intermediate connecting seat 3 toward the intermediate connecting seat 3. The end of the centering adjustment bolt 53 abuts against the side wall of the intermediate connecting seat 3. As the centering adjustment bolt 53 is tightened, the end of the centering adjustment bolt 53 pushes the corresponding angular position of the intermediate connecting seat 3 away from the lateral limiting block 51.

[0032] As described above, the centering adjustment component 5 of this case includes a lateral limiting block 51 fixedly disposed on the side of the support block 2. The lateral limiting block 51 is provided with a fourth threaded through hole 52 and a centering adjustment bolt 53 is threadedly connected in the fourth threaded through hole 52. The end of the centering adjustment bolt 53 passes through the fourth threaded through hole 52 from the outside to the inside and abuts against the side of the intermediate connecting seat 3. In this way, by tightening the centering adjustment bolt 53, the corner of the intermediate connecting seat 3 can be pushed away from the corresponding lateral limiting block 51, thereby adjusting the left and right positions of the intermediate connecting seat 3 for centering.

[0033] like Figures 1 to 5 As shown, preferably, the bottom left and right sides of the intermediate connecting seat 3 are provided with outwardly extending connecting portions 31, and the height adjustment component 4 and the centering adjustment component 5 are both connected to the connecting portions 31. In this way, the vertical and horizontal positions of the intermediate connecting seat 3 can be conveniently adjusted at a lower height.
