Description

A material guiding structure for injection molding machine

Technical Field

The utility model relates to the technical field of injection molding machines, in particular to a material guiding structure of an injection molding machine.

Background Art

The injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastic plastics or thermosetting plastics. Currently in the plastic processing industry, the injection molding machine heats the plastic raw material particles into liquid raw materials and injects them into the mold cavity to achieve cooling and molding in the cavity. When the existing injection molded parts are being injected, the material is introduced into the injection molding machine head through the material guide structure, and then the corresponding injection molding is performed.

When the existing injection molding machine introduces the material into the injection molding head, the plastic that has been softened by heating is sticky and will remain on the inner wall of the guide cylinder, resulting in the plastic not being able to be completely discharged. As a result, in the next production process of the injection molding machine, the plastic inside the guide cylinder will be mixed with the plastic remaining inside the guide cylinder, making the produced plastic products fail to meet the quality requirements.

A motor 202 is fixedly installed on the top of the fixed plate 201, and a main gear 205 is fixedly installed on the output end of the motor 202. The motor 202 can drive the driving wheel 203 to rotate, the bracket 204 is fixedly installed on the top of the fixed plate 201, and the bracket 204 is provided with two. The first gear 205 is rotatably installed on the side of the right bracket 204, and the first connecting plate 206 is rotatably installed at the eccentric part of the first gear 205. When the first gear 205 rotates, the first gear 205 can drive the first connecting plate 206 to rotate eccentrically, and the end of the first connecting plate 206 is rotatably installed with a guide rod 207, and the guide rod 207 penetrates The guide rod 207 is inserted into the guide cylinder 1 and is slidably connected with the guide cylinder 1. The eccentric rotation of the first connecting plate 206 can drive the guide rod 207 to slide up and down. A piston 208 is fixedly installed on the surface of the guide rod 207, and a scraper 209 is fixedly installed on the bottom of the guide rod 207. The up and down sliding of the guide rod 207 can drive the piston 208 and the scraper 209 to slide up and down inside the guide cylinder 1. The up and down sliding of the piston 208 can squeeze the injection molding material, so that the injection molding material can be smoothly discharged from the inside of the entire material guide mechanism 2. The sliding of the scraper 209 can scrape off the injection molding material remaining on the inner wall of the guide cylinder 1, which can not only save the time for the staff to clean the inside of the guide cylinder 1, but also prevent the injection molding material remaining in the guide cylinder 1 from polluting the next injection molding material. The side of the left bracket 204 is rotatably installed with a driven wheel 210, and a belt 211 is installed between the driven wheel 210 and the driving wheel 203. When the motor 202 drives the driving wheel 203 to rotate, the rotation of the driving wheel 203 can drive the driven wheel 210 to rotate.
