Embodiment Construction
[0016] The present invention is described in further detail below in conjunction with embodiment:
[0017] The present invention is described in further detail now in conjunction with accompanying drawing. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so that they only show the components relevant to the present invention.
[0018] See figure 1 , a lever-side core-pulling mechanism, including a movable template 1, a lever 5 with an arc chute at the left end, a fixed template 8 and a fixed mold bottom plate 9 for fixing the fixed template, and the fixed template 8 is fixed and installed through the fixed mold bottom plate 9 , the movable template 1 can move toward or away from the fixed template 8 .
[0019] The top of the movable template 1 is provided with a vertical side core hole, a lever fulcrum and an upward groove from left to right, and the movable template is prov...

The invention discloses a side core pulling mechanism with a lever. The side core pulling mechanism comprises a moving template, the lever, a fixed template and a template fixing bottom plate, whereinthe left end of the lever is provided with a circular-arc sliding chute; the template fixing bottom plate is used for fixing the fixed template; and the moving template can move towards or far away from the fixed template. The lever is rotationally fixedly mounted on a lever supporting point at the top of the moving template; a side mold core is arranged in the circular-arc sliding chute in the left end of the lever; one end of the side mold core is mounted in the circular-arc sliding chute in a sliding manner; and the other end of the side mold core stretches out from a side mold core hole in the top of the moving template to enter a mold cavity in the interior of the moving template to be used as a mold core. According to the side core pulling mechanism, the molding of a small hole in the side surface of a plastic part is realized by means of the side mold core; the circular-arc sliding chute in the lever is used for guiding and driving the side mold core to move up and down in a pin hole while the lever is overturned; and further, the side core pulling or return is realized. The side core pulling mechanism with the lever, which is provided by the invention, is simple in overallstructure and convenient to operate, and can be used for quickly finishing side core pulling and avoiding the damage to the plastic part.
Description
technical field [0001] The invention belongs to the field of polymer material molding and processing, and relates to a lever-side core-pulling mechanism. Background technique [0002] Commonly used side core-pulling mechanisms use oblique pins, slider mechanisms, or oblique sliders, rack and pinion mechanisms, or hydraulic core-pulling mechanisms. Some of these mechanisms are relatively complicated, such as oblique pin and slider mechanisms, and some are relatively expensive, such as hydraulic core pulling. The hydraulic core pull can realize side core pull for a longer distance. For shorter distance side core pulling, this application proposes a lever side core pulling mechanism, which has a simple structure, flexible mechanism and high efficiency of side core pulling. Contents of the invention [0003] In order to overcome the technical problems of complex structure and high cost of the side core-pulling mechanism in the prior art, the present invention provides a low-...
