Description

Technical Field

[0001] The utility model relates to the technical field of frames, in particular to a frame structure of an injection molding machine with high adaptability. Background Art

[0002] The injection molding machine includes a mold clamping device and an injection device. When the injection molding machine is used, it is usually fixed on the frame. The structure of the frame can refer to Figure 1 As shown, it includes four load-bearing long beams 1 distributed in a rectangular shape and load-bearing connecting rods 2 arranged between adjacent load-bearing long beams 1, and the clamping device and the injection device are mounted on the frame.

[0003] However, in actual application, the clamping device is generally larger than the injection device, and the common frame is an integrated setting with equal width. When the clamping device is matched with the frame, the frame is too large relative to the injection device, and there is a risk that the injection part cannot be mounted on the long beam of the frame or the mounting area is too small; if the injection device is matched with the frame, the frame will be smaller than the clamping device and cannot provide good support. The frame cannot be matched with the clamping device and the injection device at the same time, resulting in low stability and safety of the injection molding machine mounted on the frame. Utility Model Content

[0004] The utility model provides a highly adaptable frame structure for an injection molding machine, aiming at the disadvantages in the prior art that the frame cannot be adapted to the mold clamping device and the injection device at the same time, resulting in low stability and safety of the injection molding machine mounted on the frame.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A highly adaptable injection molding machine frame structure includes two supporting frames, the supporting frames are frame structures and a supporting table is formed at the upper end, the supporting table includes two first long beams arranged horizontally and parallel, the horizontal distance between the two first long beams is the horizontal spacing, the horizontal spacing between the two supporting frames is a large and a small setting, and the ends of the two supporting frames are fixedly connected by a fixed structure.

[0007] By adopting the above scheme, the support frames with smaller horizontal spacing are used to set up the injection device, and the support frames with larger horizontal spacing are used to set up the clamping device. The support frames can be selected or prepared according to the specific sizes of the injection device and the clamping device, and the two support frames are fixedly connected by a fixed structure, thereby ensuring the stable installation of the injection device and the clamping device and improving safety.

[0008] Preferably, the fixed structure comprises a partition, and the first long beams of the two supporting frames are respectively welded to both sides of the partition.

[0009] With the above scheme, since the horizontal spacings of the two supporting frames are different, when the horizontal spacings of the two supporting frames differ greatly, when the two supporting frames are combined, the first long beam with a small horizontal spacing and the second long beam with a large horizontal spacing cannot contact each other for welding, so a partition is provided, and the first long beams of the two supporting frames are respectively welded to both sides of the partition, and the fixed connection of the two supporting frames is ensured by the partition.

[0010] Preferably, a supporting bottom surface which can be erected on the ground is formed at the lower end of the supporting frame, and the supporting bottom surface includes two second long beams which are arranged horizontally and in parallel.

[0011] By adopting the above solution, the supporting bottom surface formed by the two second long beams can enable the supporting frame to be stably placed on the ground.

[0012] Preferably, the second long beam of one supporting frame is welded to one side of the partition, and the second long beam of another supporting frame passes through the partition and is welded to the side wall of the second long beam welded to the partition, and an avoidance groove for the second long beam to pass through is opened on the partition.

[0013] By adopting the above scheme, if the second longest beams of the two supporting frames are directly welded to the partition, the force on the partition will be too large. By adopting the above scheme, the force on the partition can be reduced, the service life of the partition can be extended, and the welding area of ​​the second longest beams of the two supporting frames can be increased, so that the connection strength is greater.

[0014] Preferably, a first reinforcing structure for reinforcing the supporting strength of the partition is provided in the supporting frame, and the first reinforcing structure includes columns arranged between adjacent first long beams and second long beams and fixedly connected to the two at both ends, and the columns are in a "C" shape with their openings facing the partition and the open ends of the columns are in contact with the partition.

[0015] With the above solution, the column is fixedly connected with the first long beam, the second long beam and the partition to strengthen the supporting strength of the partition. The column is "C" shaped and the open end fits the partition, which ensures the anti-deformation strength of the partition while reducing the material, weight and cost.

[0016] Preferably, a second reinforcement structure for reinforcing the support strength of the first long beam is provided in the support frame, and the second reinforcement structure includes a longitudinal reinforcement beam provided between adjacent first long beams and second long beams and a first cross beam provided between the two first long beams.

[0017] By adopting the above solution, the longitudinal reinforcing beam reduces the possibility of the first long beam deforming in the longitudinal direction, and the first cross beam reduces the possibility of the first long beam deforming in the horizontal direction, thereby enhancing the supporting strength of the first long beam.

[0018] Preferably, a second cross beam is provided between the two second long beams to enhance the deformation resistance of the second long beams.

[0019] By adopting the above solution, the second cross beam reduces the possibility of horizontal transverse deformation of the second long beam, thereby reducing the possibility of deformation of the longitudinal reinforcing beam, thereby enhancing the supporting strength of the first long beam.

[0020] Preferably, a through slot is passed through the partition for facilitating installation of equipment inside the two supporting racks, the side of the through slot close to the ground is connected to the ground and the avoidance slot, and the two corners of the side of the through slot away from the avoidance slot are inclined chamfers.

[0021] With the above solution, the through slot provides installation and maintenance space for the equipment inside the support rack, and the inclined chamfer resists lateral loads to avoid deformation of the partition caused by stress concentration.

[0022] Preferably, a wire threading groove is provided through the partition and is axially connected to the inside of the first long beam for easy wiring.

[0023] By adopting the above solution, the wire threading groove and the first long beam are axially connected, which provides convenience for wire threading and saves the length of the wire.

[0024] Preferably, cushion blocks are respectively provided on the upper end surfaces of the first long beams of the two supporting frames and the upper end surfaces of the partitions, and the upper end surfaces of the cushion blocks are located on the same horizontal plane.

[0025] By adopting the above solution, the cushion block protects the injection device, the mold clamping device and the supporting frame, while ensuring that the injection device and the mold clamping device can be horizontally mounted on the supporting frame.

[0026] The utility model adopts the above technical scheme, which has significant technical effects: the support frames with smaller horizontal spacing are used to set up the injection device, and the support frames with larger horizontal spacing are used to set up the clamping device, and the support frames can be selected or prepared according to the specific sizes of the injection device and the clamping device, and the two support frames are fixedly connected by a fixed structure, so as to ensure the stable setting of the injection device and the clamping device and improve safety.
