Problems solved by technology
[0006] Aiming at the deficiencies of the prior art, the present invention provides an auxiliary device for removing air bubbles and preventing dripping of molten materials for injection molding using centrifugal force. The flow rate prevents the flow rate from being too fast to cause unqualified injection molding, which solves the problems that traditional injection molding equipment cannot self-adjust the injection pressure or injection speed, and is prone to clogging the gun head caused by beneficial materials, and the existence of air bubbles in the material affects product quality.

The invention relates to the technical field of plastic material injection molding, and discloses an auxiliary device for defoaming and dripping prevention of an injection molding molten material by utilizing centrifugal force. The device comprises a conversion fan blade, a knocking block is movably connected to the outside of the conversion fan blade, a force transmission bar is movably connectedto the outside of the knocking block, and a driven wheel is movably connected to the outside of the force transmission bar. An echo wall is movably connected to the outside of the driven wheel, and acontraction wheel is movably connected into the driven wheel. Part of gravitational potential energy can be converted into mechanical energy in the material injection process so as to drive the conversion fan blade to rotate, and finally a connecting base is driven to move so as to drive the contraction wall to move in the direction close to a positioning shaft. Therefore, the injection space ofthe plastic material can be reduced. And meanwhile, the conversion fan blade rotates to continuously knock the knocking block, so that sound waves are generated and continuously act in the molten material under the sound waves, bubbles inside are removed, and the effects of preventing excessive molten material from dripping and automatically removing the bubbles in the molten material are achieved.
Description
technical field [0001] The invention relates to the technical field of injection molding of plastic materials, in particular to an auxiliary device for debubbling and anti-dripping of injection molten materials using centrifugal force. Background technique [0002] Injection molding is a method of producing industrial products. Injection molding equipment is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products with plastic molding molds. It has short molding cycle, high production efficiency and low labor intensity. , Excellent product quality and other advantages. [0003] In the process of injection molding, if the injection pressure is too large and the injection speed is too fast, the injection molded product will be cracked due to excessive internal stress, resulting in property loss of the enterprise. The plastic material will cause the gun head to be blocked, and generally there will be air bubbles in ...
