Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment, in particular to a structured frame connection device for an injection molding machine. Background Art

[0002] In the field of mechanical manufacturing technology, an injection molding machine is a common device, which is mainly used to inject molten plastic into a mold and form the required shape after cooling. In the field of plastic processing technology, the performance of the injection molding machine directly affects the quality and production efficiency of plastic products. Its frame, as the main structure, bears and fixes each key component of the injection molding machine, especially the two major components of the clamping frame and the injection frame. The frame of the injection molding machine usually consists of two parts, namely the clamping frame and the injection frame, and these two parts are connected together by positioning pins and screws. Positioning pin holes and threaded holes are machined on the connection plane of the clamping frame. The positioning pin holes must ensure the perpendicular distance accuracy from the template installation surface, and at the same time, it is also necessary to ensure symmetry with the center of the frame in the horizontal direction. The same is true for the positioning pin holes of the paired injection frame. Any uneven situation may lead to unstable mold installation, thereby affecting the dimensional accuracy and consistency of the injection molded products.

[0003] However, there are some problems with the existing fixed frame structure. First of all, once the frame of this structure is manufactured, its size and shape cannot be changed. This makes it necessary to manufacture a new frame if it is necessary to replace different models of injection molding machines or adjust the layout of the injection molding machine during actual use, which not only increases the cost but also wastes time. Secondly, due to the connection method of positioning pins and screws, the frame may be deformed during transportation and installation, which will affect the accuracy and stability of the injection molding machine. Finally, the existing frame structure is also not convenient for maintenance and repair, because once a problem occurs, the entire frame needs to be disassembled, which undoubtedly increases the workload and difficulty.

[0004] Therefore, it is necessary to propose a new structured frame connection device for an injection molding machine to solve the problems existing in the above-mentioned prior art. Summary of the Utility Model

[0030] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below in combination with relevant attached drawings and embodiments. The preferred implementation modes of the present utility model are given in the attached drawings. However, the present utility model can be implemented in many different forms and is not limited to the implementation modes described herein. On the contrary, the purpose of providing these implementation modes is to make the disclosure of the present utility model more thoroughly and comprehensively understood.

[0031] Such as Figures 1-6As shown in the figure, Embodiment 1 of the present invention provides a structured frame connection device for an injection molding machine. This frame connection device is used in the assembly of an injection molding machine to complete the connection between the clamping frame 10 and the injection frame 20. The frame connection device includes a transition connection frame 1 disposed between the clamping frame 10 and the injection frame 20. At one end of the clamping frame 10 and the injection frame 20 close to the transition connection frame 1, there are respectively provided a clamping docking plate 101 and an injection docking plate 201 adapted to the transition connection frame 1. Further refined, the clamping docking plate 101 and the injection docking plate 201 are prefabricated at one end of the clamping frame 10 and the injection frame 20 facing the transition connection frame 1 for assembly with both ends of the transition connection frame 1. The specific prefabrication form is that the clamping docking plate 101 and the injection docking plate 201 are respectively provided with a first connection convex column 1011 and a second connection convex column 2011 extending towards the transition connection plate. At both ends of the transition connection frame 1, there are respectively provided a first positioning groove 11 and a second positioning groove 12 adapted to the first connection convex column 1011 and the second connection convex column 2011. The first connection convex column 1011 and the second connection convex column 2011 are respectively positioned in the first positioning groove 11 and the second positioning groove 12 to be limited, thus completing the sequential erection connection of the clamping docking plate 101, the transition connection frame 1, and the injection docking plate 201.

[0032] Therefore, in this embodiment, after prefabricating the clamping docking plate 101 and the injection docking plate 201 at the ends of the clamping frame 10 and the injection frame 20 respectively, the sequential erection connection of the clamping docking plate 101, the transition connection frame 1, and the injection docking plate 201 can be achieved through the mating connection of the first connection convex column 1011 and the second connection convex column 2011 with the first positioning groove 11 and the second positioning groove 12 respectively. Specifically, one of the clamping frame 10 or the injection frame 20 can be hoisted to the required installation position first, then the transition connection frame 1 is hoisted to one of its ends to initially complete the lapping of the transition connection frame 1, and then the remaining one of the clamping frame 10 or the injection frame 20 is hoisted to the other end of the transition connection frame 1. The following continues to introduce the specific assembly method:

[0033] Specifically, the opening of the first positioning groove 11 faces upward, and the opening of the second positioning groove 12 faces downward; one end of the transition connecting frame 1 is erected on the second connecting stud 2011 from top to bottom through the second positioning groove 12, and the other end is snapped into the first positioning groove 11 from top to bottom through the first connecting stud 1011, thereby completing the sequential connection of the injection molding machine frame 20, the transition connecting frame 1, and the mold clamping machine frame 10. In this embodiment, first hoist the injection molding machine frame 20 to the position where it needs to be installed, then hoist the transition connecting frame 1 above the injection molding docking plate 201, so that the opening of the second positioning groove 12 is erected on the second connecting stud 2011 from top to bottom to complete the lap joint of the transition connecting frame 1; then hoist the mold clamping machine frame 10 to the other end of the transition connecting frame 1, ensuring that the first connecting stud 1011 is snapped into the first positioning groove 11 from top to bottom and limited, thereby completing the sequential connection of the injection molding machine frame 20, the transition connecting frame 1, and the mold clamping machine frame 10.

[0034] Alternatively, the opening of the first positioning groove 11 faces downward, and the opening of the second positioning groove 12 faces upward; one end of the transition connecting frame 1 is erected on the first connecting stud 1011 from top to bottom through the first positioning groove 11, and the other end is snapped into the second positioning groove 12 from top to bottom through the second connecting stud 2011, thereby completing the sequential connection of the mold clamping machine frame 10, the injection molding machine frame 20, and the transition connecting frame 1. Therefore, in this embodiment, the hoisting sequence of the mold clamping machine frame 10 and the injection molding machine frame 20 is opposite. First hoist the mold clamping machine frame 10 to the position where it needs to be installed, then hoist the transition connecting frame 1 above the mold clamping docking plate 101, so that the opening of the first positioning groove 11 is erected on the first connecting stud 1011 from top to bottom to complete the lap joint of the transition connecting frame 1; then hoist the injection molding machine frame 20 to the other end of the transition connecting frame 1, ensuring that the second connecting stud 2011 is snapped into the second positioning groove 12 from top to bottom and limited, thereby completing the sequential connection of the mold clamping machine frame 10, the injection molding machine frame 20, and the transition connecting frame 1.

[0035] The utility model adopts a structured transition connecting frame, and through the assembly design of the connecting stud and the positioning groove, the original fixed machine frame structure is improved, and problems such as poor transferability and non-replaceability of the fixed machine frame are solved;

[0036] Specifically, first-positioning grooves and second-positioning grooves with different opening directions are designed at both ends of the transition connecting frame. Then, only need to preset the clamping die docking plate, injection die docking plate and connecting studs at the opposite ends of the clamping die frame and the injection die frame. Place the clamping die frame / injection die frame first, and then through the erection and cooperation of the downward-opening positioning groove of the transition connecting frame and the connecting studs, first hoist and install the transition connecting frame at the end of the clamping die frame / injection die frame. After the positioning and installation of the transition connecting frame are completed, then hoist and install the injection die frame / clamping die frame to the other end of the transition connecting frame, and complete the connection through the clamping of the connecting studs and the upward-opening positioning groove of the transition connecting frame. The operator only needs to install the clamping die frame, the transition connecting frame and the injection die frame in sequence, without complex adjustment steps, reducing the operation difficulty and time cost.

[0037] The transition connecting frame can be adapted to different frames, greatly simplifying the installation and replacement process of the frames. The rapid frame replacement can quickly adapt to the changes in production requirements, effectively reducing the downtime in production and improving production efficiency. At the same time, the structural design of studs and positioning grooves ensures the firmness and stability of the connection, can withstand the vibration and impact brought by long-term operation and high-frequency operation, and guarantees the reliable operation of the equipment.

[0038] In the above two design methods, the first connecting stud 1011 and the second connecting stud 2011 are not on the same horizontal plane. Specifically, the horizontal height of the first connecting stud 1011 / second connecting stud 2011 that needs to be docked with the downward-opening positioning groove is designed to be lower.

[0039] In order to better complete the alignment of the first connecting stud 1011 and the first positioning groove 11, and the second connecting stud 2011 and the second positioning groove 12, preferably, the widths of the first positioning groove 11 and the second positioning groove 12 are respectively matched with the diameters of the first connecting stud 1011 and the second connecting stud 2011, and V-shaped guiding notches 13 are provided at the openings of the first positioning groove 11 and the second positioning groove 12. This can make the first connecting stud 1011 or the second connecting stud 2011 slide in.

[0040] Further introduce the structure of the transition connecting frame 1. The transition connecting frame 1 includes a connecting frame body 14. Locking plates 15 that are matched and fitted with the clamping die docking plate 101 and the injection die docking plate 201 are respectively provided at both ends of the connecting frame body 14. The first positioning groove 11 and the second positioning groove 12 are respectively arranged in the middle of the locking plates 15 at both ends of the transition connecting frame 1. This not only better realizes centering, but also the stability of the frame is higher.

[0041] The connection mode among the locking plate 15, the mold clamping docking plate 101, and the injection molding docking plate 201 is that locking holes 2 are respectively provided on both sides of the locking plate 15, the mold clamping docking plate 101, and the injection molding docking plate 201, and they are respectively locked and connected by fasteners.

[0042] To improve the structural strength of the transition connecting frame 1, a triangular reinforcing block 3 is provided between the connecting frame body 14 and the locking plate 15.

[0043] Preferably, a cover body 4 is provided on the outer periphery of the transition connecting frame 1. On the one hand, the cover body can prevent foreign objects from falling, and on the other hand, it is more aesthetically pleasing.

[0044] In summary, the design of the present utility model optimizes the traditional fixed frame structure, not only solves the limitations of the traditional fixed frame structure, but also significantly improves the flexibility, stability and production efficiency of the equipment; it has strong practicability and is suitable for large-scale promotion.

[0045] The above embodiments are only the preferred embodiments of the present utility model, and cannot be used to limit the protection scope of the present utility model. For those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
