Description

TECHNICAL FIELD

[0001] The utility model relates to injection molding machine field especially, and it is a kind of injection bench device convenient to level. BACKGROUND

[0002] The injection bench device of existing injection molding machine can refer to the injection molding mechanism disclosed by Chinese patent with announcement number CN105922524B, the injection molding mechanism includes injection seat part, injection seat part is provided with injection mechanism, injection mechanism fixedly arranged on the injection of seat part part and the pre-plastic part of guiding sliding is arranged on the injection seat part, wherein the specific structure of injection seat part can refer to the injection bench device of the utility model as shown in the description of the drawings, including sliding base, injection seat body is provided on the sliding base, injection part is fixed on the injection seat body, a pair of second guide parts is provided on the two sides of injection seat body in parallel, pre-plastic part and second guide part are guided sliding connection, four groups of adjusting assemblies for adjusting the height of injection seat body by lifting are arranged between the four corners of sliding base and injection seat body. Figure 1

[0003] The above-mentioned injection bench can drive the injection nozzle on the injection bench to align the injection position of mold by adjusting the injection bench to the required height first, and then adjusting the injection seat to the required plane, and each adjusting assembly needs to be adjusted in sequence to achieve the effect of lifting the whole injection bench during adjustment, since one plane can be formed between every three adjusting assemblies, and four adjusting assemblies can form four planes, and the error generated during adjustment causes these planes to intersect with each other, and adjusting one adjusting assembly alone will change the flatness of the three planes, therefore, it is necessary to repeatedly adjust each adjusting assembly and measure the flatness of each part of the injection seat until these planes approach the required plane to reduce the flatness error, which makes the adjustment process of the injection seat very complex. SUMMARY

[0004] In view of the shortcomings that the existing injection seat is prone to error when adjusting height, and the adjustment process for reducing error is very complex, the purpose of the utility model is to provide an injection bench device for conveniently adjusting flatness error.

[0005] To solve the above technical problems, the utility model solves them by the following technical schemes:

[0006] A kind of injection bench device convenient to level, including injection seat and injection part main body installed on the upper end surface of injection seat, injection seat is set on the sliding base that is guided sliding along the injection direction of injection part main body, adjusting assembly is set between sliding base and injection seat, and the flatness and longitudinal height of injection seat are adjusted by lifting, adjusting assembly is provided with three groups and is distributed in triangle.

[0007] ​Adopting the above scheme, the three sets of adjusting assemblies form a unique plane for determining the flatness of the injection seat, and when adjusting, the injection seat is only needed to be lifted to the required height and then leveled, thereby omitting the complex process of adjusting multiple planes and repeatedly measuring and adjusting to approach the required plane, and making the leveling process of the injection table simpler and more convenient.

[0008] In the prior art, the actual flatness of the injection seat is formed by four planes, and therefore until the overall adjustment of the injection seat is completed, at least one corner of the injection seat is in a deformed state, which will cause permanent deformation of the injection seat after long-term use, and the deformation amount also becomes one of the factors affecting the flatness of the injection seat, thereby reducing the flatness precision of the injection seat and making it difficult to adjust. In the present scheme, only one unique plane constitutes the actual flatness of the injection seat, and the overall injection seat will move regardless of the height change of any adjusting assembly, thereby significantly reducing the deformation probability of the injection seat, simplifying the complexity of the injection seat leveling process, and ensuring the flatness precision of the injection seat.

[0009] As a preferred embodiment, the injection part body comprises an injection part fixed on the upper end face of the injection seat and a pre-plastic part guided to slide along the injection direction of the injection part, the upper end face of the injection seat extends in the injection direction of the injection part to form a guide part for guiding the pre-plastic part to slide and connect, and the end of the injection part away from the pre-plastic part is fixedly provided with a barrel, and the center line of the extension direction of the guide part is parallel to the axis of the barrel and located on a plane perpendicular to the injection seat.

[0010] Adopting the above scheme, the position of the guide part in the present scheme is in the center of the upper end face of the injection seat, which plays a role in bearing the weight of the injection part. Compared with the existing two guide parts, the guide part can also limit the guided movement of the injection part, thereby reducing the manufacturing cost.

[0011] As a preferred embodiment, one of the three sets of adjusting assemblies is located below the center of gravity of the pre-plastic part, and the remaining adjusting assemblies are symmetrically or asymmetrically arranged on both sides of the guide part.

[0012] Adopting the above scheme, when one of the adjusting assemblies is located directly below the guide part, the center of gravity of the injection seat and the pre-plastic part is directly opposite to the adjusting assembly, and the weight is mainly concentrated on the adjusting assembly, thereby balancing the stress condition of the adjusting assembly. In the present scheme, the remaining two adjusting assemblies are symmetrically arranged on both sides of the guide part, which is the optimal choice. In this state, the adjusting assemblies form an isosceles triangle, thereby further balancing the stress of the adjusting assemblies.

[0013] As preferred, the injection seat comprises a bottom frame connected with the sliding base through the adjusting assembly, and support components vertically arranged on both sides of the bottom frame, the support components are distributed in a non-parallel state and form a first mounting position for the guide component at the intersection, and the support components form a second mounting position for the shooting component away from the first mounting position.

[0014] By the above scheme, the support components are distributed on both sides of one end of the bottom frame and converge to the other end to form an intersection, which aims to reduce the load distribution area of the injection seat and reduce the possibility of deformation of the injection seat caused by the overhanging part of the injection seat beyond the adjusting assembly.

[0015] As preferred, the adjusting assembly comprises a screw vertically rotating on the sliding base, and a threaded bushing fixed on the injection seat and threadedly connected with the screw, and the screw is provided with an operation block capable of synchronous rotation with the screw.

[0016] By the above scheme, the screw is driven to rotate by rotating the operation block, and the threaded bushing is fixed on the injection seat, so that the threaded bushing moves up and down along the screw when the screw rotates, thereby achieving the lifting of the injection seat.

[0017] The above technical scheme has the following technical effects: three adjusting assemblies form a unique plane for determining the flatness of the injection seat, and the injection seat is lifted to the required height during adjustment, and then the plane is leveled, which omits the complex process of adjusting multiple planes and repeatedly measuring and adjusting to approach the required plane. In the present scheme, only one unique plane constitutes the actual flatness of the injection seat, and the overall injection seat will move regardless of the height change of any adjusting assembly, so that the present scheme significantly reduces the deformation probability of the injection seat, simplifies the complexity of leveling the injection seat, and ensures the accuracy of the flatness of the injection seat.

[0025] As shown in the figure, Figure 2 , 3 As shown in the figure, the adjusting assembly 3 is arranged between the sliding base 2 and the injection seat 1 to adjust the flatness and longitudinal height of the injection seat 1 by lifting, the adjusting assembly 3 is arranged in three groups and is distributed in a triangular shape, in this embodiment, one of the three groups of adjusting assemblies 3 is located below the center of gravity of the pre-plastic part 5, and the remaining adjusting assemblies 3 are symmetrically arranged on both sides of the guide part 6.

[0026] The adjustment component 3 includes a screw that is vertically rotatably mounted on the sliding base 2 and a threaded bushing that is fixedly mounted on the injection seat 1 and threadedly connected to the screw. The screw is provided with an operating block that can rotate synchronously with itself. Since the above-mentioned adjustment component 3 is prior art and not the main improvement point of this embodiment, the detailed structure of the adjustment component 3 is not shown in the figure. For a specific structural schematic, please refer to the injection molding machine injection table lifting adjustment structure disclosed in Chinese Patent No. CN202607996U, which includes a base plate, a screw, an injection table, and a fixed shaft.
