Description

Technical Field

[0001] The utility model relates to the field of injection molding machines, and specifically to a hoisting structure for the mold clamping part of an injection molding machine. Background Art

[0002] The existing hoisting structure is to set a positioning mechanism on the mold clamping frame. The pressing plate on the positioning mechanism is connected to the mold clamping mechanism. The pressing plate of the positioning mechanism presses the hoisting mechanism, forming a series of hoisting processes where the lifting rope pulls the hoisting mechanism, the hoisting mechanism drives the pressing plate, and the pressing plate drives the mold clamping mechanism. In this technical solution, since the pressing plate needs to protrude a certain distance to press the feet of the hoisting mechanism, the distance between the mold clamping mechanism and the positioning mechanism is relatively compact. If the customer wants to increase the mold capacity slightly, due to insufficient space, the pressing plate cannot be retracted, and many components need to be disassembled, and then complex customization needs to be done additionally, which prolongs the delivery cycle of the machine to the customer. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a hoisting structure for the mold clamping part of an injection molding machine that can increase the mold capacity slightly and is easy to disassemble.

[0004] The above purpose is achieved as follows.

[0005] A hoisting structure for the mold clamping part of an injection molding machine includes a mold clamping mechanism and a mold clamping frame. The mold clamping mechanism includes a fixed template, a tail plate, and guide columns. The fixed template and the tail plate are connected by a plurality of guide columns. The fixed template and the tail plate are respectively arranged at both ends of the mold clamping frame. The tail plate is connected to the mold clamping frame by bolts. The tail plate is connected to the mold clamping frame through a positioning structure. The positioning structure includes a pressing plate and a lifting support rod. The positioning structure is separated from the tail plate. The pressing plate is fixedly connected to the mold clamping frame by bolts. One end of the lifting support rod is arranged inside the pressing plate body, and the other end is arranged inside the tail plate body.

[0006] The purpose of the utility model can also be optimized by adopting the following technical measures.

[0007] Preferably, the pressing plate can be stacked by one or more plates, and the pressing plate body is provided with mounting holes for the lifting support rod to pass through.

[0008] Preferably, the two ends of the lifting support rod have different diameters. The diameter of the end of the lifting support rod arranged inside the pressing plate body is smaller, and the diameter of the end of the lifting support rod arranged inside the tail plate body is larger.

[0009] After adopting the above technical solution, the utility model uses the lifting support rod to drive the mold clamping frame, and when the user needs to adjust the mold capacity, only the length of the lifting support rod needs to be changed for corresponding adjustment, reducing the accessories that need to be disassembled when adjusting the mold capacity and simplifying the operation process. Brief Description of the Drawings

[0015] Combined with Figure 1 , a hoisting structure of the mode-locking part of an injection molding machine, including a mode-locking mechanism and a mode-locking frame 3. The mode-locking mechanism includes a fixed template 1, a tail plate 2 and a guide pillar 5. The fixed template 1 and the tail plate 2 are connected by a plurality of guide pillars 5, and the fixed template 1 and the tail plate 2 are respectively arranged at both ends of the mode-locking frame 3.

[0016] Combined with Figure 3 , the tail plate 2 is connected to the mode-locking frame 3 by bolts.

[0017] Combined with Figure 2 , the tail plate 2 is connected to the mode-locking frame 3 through a positioning structure. The positioning structure includes a pressure plate 41 and a lifting support rod 42. The positioning structure is separated from the tail plate 2. The pressure plate 41 can be stacked by one or more plates. The pressure plate 41 is fixedly connected to the mode-locking frame 3 by bolts. An installation hole is provided in the pressure plate 41 for the lifting support rod 42 to pass through. One end of the lifting support rod 42 is arranged inside the pressure plate 41, and the other end is arranged inside the tail plate 2. The diameters of both ends of the lifting support rod 42 are different. The diameter of the end of the lifting support rod 42 arranged inside the pressure plate 41 is smaller, and the diameter of the end of the lifting support rod 42 arranged inside the tail plate 2 is larger.
