Embodiment 1

[0028] Such as Figure 1 to Figure 4 As shown, this embodiment designs a semi-automatic plastic extruding mechanism for cup lid molding, including a cup lid injection mold 1 , an injection molding table 2 and a feeding structure 3 .

[0029] The cup lid injection mold 1 includes a lower mold body 11 and an upper mold body 12, a mold cavity 14 is arranged inside the cup lid injection mold 1, and the lower mold body 11 and the upper mold body 12 are mutually rotatably connected. The bottom is provided with an injection port 15 communicating with the mold cavity 14, and the mold cavity 14 is positioned between the lower mold body 11 and the upper mold body 12. In addition, a mandrel is also provided at the bottom of the lower mold body 11, and the injection port 15 is positioned at the center of the mandrel. Directly below, a passage for connecting the mold cavity 14 and the injection port 15 is formed between the lower mold body 11 and the core mold, so that molten plastic can b...

Abstract

The invention belongs to the technical field of injection molding of plastic cup covers, and particularly relates to a semi-automatic plastic extrusion mechanism for cup cover forming. The semi-automatic plastic extrusion mechanism comprises a cup cover injection mold, an injection molding table and a feeding structure; a feeder is matched with an outer shell, so that the integration of three functions of plastic stirring, plastic conveying and uniform mixing can be realized, and the structure of the equipment is effectively simplified; meanwhile, an upper auger and a lower auger of the feeder are of a mutually independent structure and a mutually one-way transmission mode, so that the stirring function and the conveying function can be separated, and the stirring operation can be independently executed; an auxiliary stirrer can increase the uniform stirring speed of plastic in a stirring cavity, simplify the structure of a plastic extrusion mechanism and realize structural integration; and different temperature control modes are arranged in the side walls of a uniform mixing cavity, the conveying cavity and the stirring cavity correspondingly, so that the plastic can be melted to different degrees according to the functions of stirring, conveying, uniform mixing and the like, and energy conservation and smooth production are realized.

Description

technical field [0001] The invention belongs to the technical field of injection molding of plastic cup lids, and in particular relates to a semi-automatic plastic extruding mechanism for molding cup lids. Background technique [0002] Injection molding is also called injection molding. Its working principle is similar to that of a syringe for injection. It is a molding method of injection and molding. It can stir the completely molten plastic material through the screw and inject it into the mold cavity with high pressure. After cooling and solidification, molded products are obtained. The advantage of this method is that the production speed is fast, the efficiency is high, the operation can be automated, there are many kinds of designs and colors, the shape can be changed from simple to complex, and the size can be changed from large to small, and the product size is accurate, the product is easy to replace, and it can complete complex shapes. In the manufacture of compo...
