Abstract
Description
Technical Field
[0001] This utility model relates to the field of material storage in injection molding machines, specifically a material storage structure for injection molding machines. Background Technology
[0002] Injection molding is a method of industrial product manufacturing. Products are typically made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. An injection molding machine is the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting materials. Injection molding is achieved through an injection molding machine and molds.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 5As shown, a material storage structure for an injection molding machine includes a storage tank 1. A feed pipe 12 is connected to the top of the storage tank 1, and a discharge pipe 13 is connected to the bottom of the storage tank 1. A motor 14 is fixedly connected to the top of the storage tank 1, and a rotating rod 15 is fixedly connected to the output end of the motor 14. The rotating rod 15 is rotatably connected to the storage tank 1. A first stirring rod 16 is fixedly connected to the surface of the rotating rod 15. A sieve plate 17 is fixedly connected to the inner side of the storage tank 1, and the sieve plate 17 is rotatably connected to the rotating rod 15. A second stirring rod 18 is fixedly connected to the side of the rotating rod 15, and the bottom of the second stirring rod 18 is in contact with the sieve plate 17. A heating layer 19 is fixedly connected to the surface of the storage tank 1. During operation, raw materials are poured into the storage tank 1 through the feed pipe 12. When the raw materials pass through the sieve plate 17, larger materials are blocked, while smaller materials fall through the sieve plate 17. The motor 14 drives the rotating rod 15 and the second stirring rod 18 to rotate. Rotating rod 15 drives the first stirring rod 16 to rotate, stirring the raw materials inside the storage tank 1. The second stirring rod 18 stirs the raw materials on the surface of the sieve plate 17, breaking up larger raw materials so that they fall through the sieve plate 17. Hot water is added to the heating layer 19, heating the storage tank 1. The storage tank 1 is heated, and the raw materials inside are heated. The discharge pipe 13 is opened to discharge the raw materials. In this step, the second stirring rod 18 can block larger raw materials and break them up by rotating, making it easier for them to fall through the sieve plate 17. The rotation of the second stirring rod 18 and the first stirring rod 16 continuously stirs the raw materials inside the storage tank 1. Combined with the heating of the heating layer 19, this raises the temperature of the raw materials and prevents them from clumping due to prolonged storage.
[0024] like Figures 2 to 4 As shown, a first heat-conducting pipe 21 is fixedly connected to the inner side of the storage tank 1. The first heat-conducting pipe 21 is connected to the heating layer 19, and a second heat-conducting pipe 22 is connected to the side of the first heat-conducting pipe 21. During operation, when hot water is added to the heating layer 19, the hot water will enter the interior of the first heat-conducting pipe 21 and the second heat-conducting pipe 22 through the storage tank 1. The heat is transferred to the interior of the storage tank 1 through the first heat-conducting pipe 21 and the second heat-conducting pipe 22 to heat the raw materials. This step can transfer the heat inside to the interior of the storage tank 1 more quickly through the first heat-conducting pipe 21 and the second heat-conducting pipe 22, increasing the efficiency of heating the raw materials.
[0025] like Figures 2 to 4As shown, a first scraper 31 is fixedly connected to the side of the first stirring rod 16, and a second scraper 32 is fixedly connected to the surface of the rotating rod 15. The sides of both the first scraper 31 and the second scraper 32 are in contact with the inner wall of the storage tank 1. During operation, when the first stirring rod 16 rotates, it drives the first scraper 31 to rotate, and when the rotating rod 15 rotates, it drives the second scraper 32 to rotate. In this step, when the first scraper 31 and the second scraper 32 rotate, they can scrape and clean the inner wall of the storage tank 1 to prevent the raw materials from accumulating on the inner wall of the storage tank 1. When the first stirring rod 16 rotates, it can scrape off the raw materials remaining on the top of the first heat conduction pipe 21 and the second heat conduction pipe 22.
[0026] like Figures 2 to 4 As shown, a sealing cover 41 is slidably connected to the top of the feed pipe 12, and a heat insulation pad 42 is fixedly connected to the bottom of the sealing cover 41. The heat insulation pad 42 is slidably connected to the feed pipe 12. During operation, pulling the handle on the top of the sealing cover 41 can move the sealing cover 41, causing it to separate the heat insulation pad 42 from the feed pipe 12. At this time, the feed pipe 12 is opened. This step, through the sealing cover 41 and the heat insulation pad 42, can seal the top of the feed pipe 12, reduce the outflow of heat from the inside of the storage tank 1, and prevent dust from entering the inside of the storage tank 1 through the feed pipe 12.
[0027] like Figures 2 to 4 As shown, a spiral blade 51 is fixedly connected to the bottom of the rotating rod 15, and the spiral blade 51 extends to the inner side of the discharge pipe 13. During operation, when the rotating rod 15 rotates, it drives the spiral blade 51 to rotate. When the discharge pipe 13 is opened for material discharge in this step, the rotation of the spiral blade 51 can make the raw material flowing through the discharge pipe 13 flow evenly.
[0028] like Figures 2 to 4 As shown, a stirring plate 61 is fixedly connected to the side of the first stirring rod 16, and an opening is provided inside the stirring plate 61. During operation, the first stirring rod 16 rotates while driving the stirring plate 61 to rotate. This step can increase the range of material stirring and increase the efficiency of material stirring through the stirring plate 61.
[0029] Working principle: Pulling the handle on the top of the sealing cover 41 moves the sealing cover 41, causing it to separate the heat insulation pad 42 from the feed pipe 12. At this time, the feed pipe 12 is opened, and the raw material is poured into the storage tank 1 through the feed pipe 12. When the raw material passes through the sieve plate 17, larger pieces are blocked, while smaller pieces fall through the sieve plate 17. The motor 14 drives the rotating rod 15 and the second stirring rod 18 to rotate. The rotating rod 15 drives the first stirring rod 16 to rotate, stirring the raw material inside the storage tank 1. The second stirring rod 18 stirs the raw material on the surface of the sieve plate 17, breaking up larger pieces and allowing them to fall through the sieve plate 17. Hot water is added to the interior of the heating layer 19 to heat the storage tank 1, which in turn heats the raw materials inside. When hot water is added to the heating layer 19, it enters the interior of the first heat-conducting pipe 21 and the second heat-conducting pipe 22 through the storage tank 1. The heat is then transferred to the interior of the storage tank 1 through the first heat-conducting pipe 21 and the second heat-conducting pipe 22 to heat the raw materials. When the first stirring rod 16 rotates, it drives the first scraper 31 to rotate. When the rotating rod 15 rotates, it drives the second scraper 32 to rotate. When the rotating rod 15 rotates, it drives the spiral blade 51 to rotate, opening the discharge pipe 13 to discharge the raw materials. The spiral blade 51 ensures that the raw materials inside the discharge pipe 13 flow evenly.
