Efficient injection molding piece surface repairing device

Abstract

The invention discloses an efficient injection molding piece surface repairing device, and relates to the technical field of injection molding pieces. The efficient injection molding piece surface repairing device comprises a particle containing chamber and an injection molding piece positioning device. The particle containing chamber is supported through a supporting frame and located over the injection molding piece positioning device. An air nozzle is arranged on an outlet of the particle containing chamber. The injection molding piece positioning device comprises a lifter, a repairing chamber and a positioning mechanism. A strip-shaped through groove is formed in the bottom of the repairing chamber. A particle collecting bin is arranged at the lower end of the repairing chamber. The repairing chamber is arranged at the lifting end of the lifter. A left rotation mechanism is arranged on a left clamping plate, and a right rotation mechanism is arranged on a right clamping plate. Through positioning of an injection molding piece, high stability of the injection molding piece in the repairing process is guaranteed, in addition, injection molding pieces different in size can be positioned, and the applicable flexibility is high. A servo motor can conduct comprehensive repairing on the injection molding piece in the rotation process, and the repairing efficiency is improved. Theparticle collecting bin is arranged at the lower end of the repairing chamber so that particles can be rapidly and efficiently recycled.

Description

technical field [0001] The invention relates to the technical field of injection molded parts, in particular to a device for efficiently repairing the surface of injection molded parts. Background technique: [0002] With the continuous improvement of people's living standards, consumer electronic products such as mobile phones and tablet computers have become more and more popular. On the basis of increasingly powerful functions, the texture of the plastic shell and the three-dimensional effect of the pattern have increasingly become the choice of consumers. At present, there are many problems when spraying the plastic shell of the product: 1. The spray paint layer is too thick; 2. The spray paint particles are too thick; 3. The uniformity of the spray paint is poor; 4. The wear resistance is poor; ; 6. Problems with the use of spray-painted substrates; 7. Spray-paint affects the strength of the material; 8. Dirty spots on the spray-painted surface. [0003] And the tradit...

[0002] With the continuous improvement of people's living standards, consumer electronic products such as mobile phones and tablet computers have become more and more popular. On the basis of increasingly powerful functions, the texture of the plastic shell and the three-dimensional effect of the pattern have increasingly become the choice of consumers. At present, there are many problems when spraying the plastic shell of the product: 1. The spray paint layer is too thick; 2. The spray paint particles are too thick; 3. The uniformity of the spray paint is poor; 4. The wear resistance is poor; ;6. Problems with the application of spray paint substrates; 7. Spray paint affects the strength of the material; 8. Dirty spots on the spray paint surface

[0005] However, in the technical solution of the above-mentioned patent, in the process of repairing the surface of the injection molded part, since the injection molded part is placed on the conveyor belt, the positioning of the injection molded part is unstable, and the particles will collide with the surface of the injection molded part during repair. The injection molded parts will shake (in severe cases, the injection molded parts will be "flushed" from the conveyor belt). In addition, the particles will "splash" everywhere during the collision with the injection molded parts, causing the particles to scatter everywhere in the confined space. , the suction hood cannot collect particles efficiently and stably, and at the same time, the repair efficiency is low, and it is impossible to repair the surface of injection molded parts in an all-round way
