Equipment for overlap injection molding of fragile hollow products

Abstract

The invention discloses equipment for overlap injection molding of fragile hollow products. The equipment comprises a stacking manipulator, a machining support table, a syringe injection molding machine, an air pipe cover, an air collecting valve, an industrial control main board, a power distribution box, an air pressure pump body, a motor groove base and a bearing base; the syringe injection molding machine is mechanically connected with the air collecting valve through the air pipe cover; the air collecting valve is inserted in the axis of the air pipe cover, and communicates with the same;the syringe injection molding machine is provided with an air pressure cylinder set, a lifting device, a ratchet mechanism, a traction device, a speed reducing mechanism, a shaft rod device, a collision mechanism and a syringe device; the effect of an injection molding machine combined with syringe pushing is achieved; the inner space pressure outputting is effectively mastered; the pressure is limited in the hollow product bearing range; and a syringe adopts fine-caliber outputting, is embedded in the product injection molding to isolate air disturbance dust and particle impurities for uniform covering injection molding to reach a saturated state, so that whole products are full, the fragile hidden trouble caused by internal gaps is prevented, and the pressure and the output flow are efficiently controlled.

Description

technical field [0001] The invention relates to equipment for overlapping injection molding fragile hollow products, which belongs to the field of injection molding equipment. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. It is divided into vertical, horizontal, and all-electric types. The injection molding function Heating the plastic and applying high pressure to the molten plastic to make it inject and fill the mold cavity. The vertical injection molding machine commonly used in the current technology has a relatively high injection pressure for fragile hollow products. Pressing down by self-weight, unloading force left and right in the fragile hollow product and pushing the product, vertical large-scale injection molding materials will also cause air d...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a device for overmolding fragile hollow products, so as to solve the problem that the injection pressure of vertical injection molding machines for fragile hollow products is too high, and the pressure drop injection molding method is often used. As a result, during the injection molding process, the material is pressed down by its own weight, and the fragile hollow product is unloaded left and right to push the product, and the vertical large-scale injection molding material will also cause air dust and particles to be mixed in, and the processing of impurities will cause the hollow product to have insufficient internal plumpness. There is a gap, and the problem of crushing and breaking
