Description

Technical Field

[0001] The present invention relates to a colander forming machine, and more particularly to a colander forming machine. Background Art

[0002] The colander forming machine is a forming equipment specially used for producing colanders.

[0003] The working principle of the colander forming machine is to inject the plasticized molten plastic (or other materials) into a closed mold cavity, and obtain the finished product after solidification and shaping.

[0004] After the colander forming machine is processed, the raw materials adhere to the injection port of the mold, and the impurities on the outer surface easily enter the mold cavity through the upper and lower molds, thereby increasing the wear of the mold by the raw materials attached to the injection port and the impurities entering the mold cavity, and even causing damage to the mold, shortening the service life of the mold.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention aims to provide a colander forming machine. When the scraper column is pushed downward by the first cylinder, the blade of the scraper column slides along the inner wall of the injection port to scrape off the attached raw material residues, and the raw material residues in the injection port are cleaned regularly, thereby reducing equipment wear and failure caused by residue accumulation. The sealing plate is pushed upward to the outer surface of the upper mold and the lower mold by the second cylinder, thereby forming an effective sealed cavity. This design can significantly improve the sealing performance of the mold, prevent external impurities from entering the mold cavity, prevent mold damage, and extend the service life of the mold.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a colander forming machine, comprising a base, a support frame is fixedly installed on the left side of the upper end of the base, a first cylinder is fixedly installed on the upper end of the support frame, a movable cover plate is fixedly installed on the output end of the first cylinder, a lower mold is provided at the upper end of the base, an upper mold is provided on the lower mold, an injection port is fixedly installed on the upper end of the upper mold, a mold cavity is opened on the lower mold, a scraper column is fixedly installed on the right side of the lower end of the movable cover plate, the diameter of the scraper column is the same as the inner diameter of the injection port, a sealing plate is movably connected to the outer surface of the lower mold, a movable plate is fixedly installed on the left and right sides of the sealing plate, two second cylinders are fixedly installed on the lower end of the base, and the second cylinder and the movable plate are fixedly connected.

[0008] The present invention is further configured as follows: the upper end of the movable cover plate is fixedly connected to a limiting rod, and the limiting rod is movably inserted and connected to the support frame.

[0009] The present invention is further configured such that the axis lines of the scraper column and the injection port coincide with each other.

[0010] The present invention is further configured as follows: four supporting legs are fixedly mounted on the lower end of the base.

[0011] The present invention is further configured such that: the sealing plate is configured in a loop shape.

[0012] The present invention is further configured as follows: a guide rod is movably inserted between the lower die and the upper die.

[0013] The present invention is further configured as follows: the support frame is configured in an L shape.

[0014] In summary, the present invention has the following beneficial effects:

[0015] 1. When the scraper column is pushed downward by the first cylinder, the blade of the scraper column will slide along the inner wall of the injection port to scrape off the attached raw material residues. The raw material residues in the injection port are cleaned regularly, reducing equipment wear and failure caused by residue accumulation. The sealing plate is pushed upward to the outer surface of the upper and lower molds by the second cylinder, thus forming an effective sealed cavity.

The raw material in the molten state is then introduced into the mold cavity 8, and the mold cavity 8 is in the shape of a colander for injection molding. After processing, demolding is performed, and the movable cover plate 4 is pushed downward by the first cylinder 3 to drive the scraper column 9 to move downward and insert into the injection port 7. The scraper column 9 usually has a contour matching the shape of the injection port 7 and can fit tightly against the inner wall of the injection port 7. The material of the scraper column 9 is generally selected from high-hardness, high-wear-resistant steel materials to ensure that the injection port 7 is not damaged when scraping the raw material, while keeping the cutting edge sharp. When the first cylinder 3 pushes the scraper column 9 to move downward, the cutting edge of the scraper column 9 will slide along the inner wall of the injection port 7 to scrape off the attached raw material residues, regularly clean the raw material residues in the injection port 7, and reduce equipment wear and failure caused by residue accumulation. The sealing plate 10 is pushed upward by the second cylinder 12 to the outer surfaces of the upper mold 6 and the lower mold 5, thereby forming an effective sealed cavity. This design can significantly improve the sealing performance of the mold, prevent external impurities from entering the mold cavity 8, prevent the mold from being damaged, and extend the service life of the mold.

[0025] The upper end of the movable cover plate 4 is fixedly connected with a limit rod 13, and the limit rod 13 is movably connected to the support frame 2. The limit rod 13 is provided to limit the movable cover plate 4 to prevent the movable cover plate 4 from being offset when moving up and down.

[0026] Four supporting legs 14 are fixedly mounted on the lower end of the base 1 , and the supporting legs 14 provide support and stability to the base 1 .

[0027] A guide rod 15 is movably inserted between the lower mold 5 and the upper mold 6 , and the guide rod 15 is provided to guide the upper mold 6 and the lower mold 5 to close the mold.

[0028] Working principle: when the upper mold 6 moves downward, it closes the mold with the lower mold 5, and the raw material in the molten state is conveniently introduced into the mold cavity 8 through the injection port 7. The mold cavity 8 is in the shape of a colander for injection molding. After processing, demolding is performed. When the movable cover plate 4 is pushed downward by the first cylinder 3, the scraper column 9 is driven to move downward and insert into the injection port 7. The scraper column 9 usually has a contour matching the shape of the injection port 7 and can fit tightly against the inner wall of the injection port 7. The material of the scraper column 9 is generally selected from high-hardness, high-wear-resistant steel materials to ensure that the injection port 7 is not damaged when scraping the raw material, while keeping the cutting edge sharp. When the first cylinder 3 pushes the scraper column 9 to move downward, the cutting edge of the scraper column 9 will slide along the inner wall of the injection port 7 to scrape off the attached raw material residues. The raw material residues in the injection port 7 are cleaned regularly, which reduces equipment wear and failure caused by residue accumulation. The sealing plate 10 is pushed upward to the outer surface of the upper mold 6 and the lower mold 5 by the second cylinder 12, thereby forming an effective sealed cavity. This design can significantly improve the sealing performance of the mold, prevent external impurities from entering the mold cavity 8, prevent the mold from being damaged, and extend the service life of the mold.
