technical field

The utility model relates to the technical field of injection molding machine design, in particular to a supporting and guiding structure of an injection molding machine plate.

Background technique

Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. The opening and closing of the mold is an important part of the work of the injection molding machine. On the injection molding machine, the movable plate is usually used to drive the movement of the movable mold, so as to realize the opening and closing of the mold.

In common injection molding machines, in order to ensure the reliability of moving plate movement, guide pillars are usually set on the injection molding machine so that the movable plate can move along the guide pillars. Pillar contact, on the one hand, when the moving plate moves on the guide post, it will cause wear and tear on the moving plate and the guide post. After a long time of use, it will seriously reduce the movement accuracy of the moving plate and reduce the precision of mold opening and closing. On the one hand, since the moving plate is installed on the guide post, when the high-pressure mold clamping is performed, the moving plate will deform to a certain extent and apply shear force to the guide post, which will cause the guide post to change shape, and even damage it in severe cases. guide post.

The setting of the tail plate can conveniently limit the position of the guide post, so as to avoid the displacement of the guide post when the utility model is in use.

In some embodiments, there are two supporting blocks, the two supporting blocks are respectively connected to two sides of the moving plate, and the two supporting blocks are arranged symmetrically. As a result, the stress on the two support blocks can be equalized to prolong their service life.

In some embodiments, there are four guide pillars, the four guide pillars are arranged in parallel, the four ends of the fixed plate are respectively sleeved on the four guide pillars, two of the guide pillars are located below, and respectively Through the two support blocks, the other two guide columns are located above. Thus, the movement of the utility model can rely on the guidance of the two guide pillars, further improving its movement accuracy.

In some embodiments, there are four sliders, two sliders are connected to one support block, and the other two sliders are connected to another support block. The arrangement of multiple sliders can prevent the whole structure from being unable to work normally when a single slider fails, and improves the fault tolerance rate of the utility model.

In some embodiments, there are two guide rails, the two guide rails are arranged parallel to the guide post, one end of the two guide rails is connected to the fixed plate, and the two sliders are set on one guide rail , and the other two sliders are set on another guide rail.

In some embodiments, the distance between the surface of the guide post and the inner wall of the through hole is 5 mm. According to experiments, it is best to use this distance as a criterion for whether the movement deviation or deformation of the movable plate is excessive.
