Description

Technical Field

[0001] The invention relates to the technical field of injection molds, and in particular to a feeding device for an injection shoe mold. Background Art

[0002] With the wide application of plastics in various fields, the manufacturing process, manufacturing technology and manufacturing equipment of plastic materials have been well developed. In the field of shoemaking molds, many of them need to be injected with plastics, and they are widely used in the production field. Injection molding generally melts the resin material in the barrel, and through the push of the screw, the molten plastic is quickly injected into the mold cavity through the nozzle of the injection molding machine, and then the injection molded product is obtained after solidification and shaping. Injection shoe molds are commonly used molding equipment in the shoe manufacturing process. The injection molding machine can greatly improve the production efficiency and production quality of shoes. The feeding device is an indispensable part of the mold. The feeding device determines the quality of the raw materials when entering the mold cavity, and then determines the quality of the shoes after molding;

[0003] When feeding into an injection mold, materials are usually injected into the mold cavity through a nozzle. However, it is difficult for the injected materials to fully fill the mold cavity. There are often gaps between the materials that seem to fill the mold cavity, or the density of the materials is relatively sparse, which seriously affects the quality of the injection molded product after molding. Therefore, we propose a feeding device for injection shoe molds. Summary of the invention

The bottom of the curved scraper rod is fixedly connected with a tail rear needle, which peels and cleans the discharge port of the spray pipe when the tail rear needle rotates to prevent the discharge port of the spray pipe from being continuously accumulated with mixed raw materials and gradually accumulating and clogging the discharge port.

When the arc scrapers 6074 move up to the top of the semicircular baffle 604, the inner inclined arc plates 6076 move up to the top of the semicircular baffle 604. At this time, the electric push rod 6071 drives the arc scrapers 6074 to move down, so that the inclined arc plates 6076 move down together.

At this time, the electric push rod 6071 drives the arc scraper 6074 to move down so that the inclined arc plate 6076 moves down together. When the inclined arc plate 6076 moves down, it scrapes and cleans the top surface of the semicircular baffle 604. By opening an arc through hole 6075 and an inclined arc hole 6077 on the surface of the arc scraper 6074 and the surface of the inclined arc plate 6076 respectively, the surface area that can be attached is reduced to facilitate the passage of mixed raw materials.

[0052] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
