DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0025] Example 1:

[0026] like Figure 1-4 As shown, the utility model provides a springboard ejection mold for facilitating the demoulding of products with extra-long ribs, comprising: a lower mold 1 and an upper mold 2, wherein the lower mold 2 is provided with a cavity 5, the upper mold 2 is aligned with the lower mold 1 and molded, and injection molding is performed into the cavity 5 through the injection hole on the upper mold 2, and finally a product 3 with extra-long ribs is made. In order to facilitate the demoulding of the product 3, a demoulding mechanism 4 is provided below the lower mold 1, and the demoulding mechanism 4 includes a rectangular frame 6 provided below the lower mold. When in use, a driving source should be provided below the rectangular frame 6 so that the rectangular frame 6 can be lifted and lowered, and a lifting plate 7 is provided inside the rectangular frame 6. A plurality of electric push rods 8 are installed between the lifting plate 7 and the rectangular frame 6 (other types of driving sources, such as cylinders, etc., can also be used). A plurality of separation components 9 are evenly installed on the top of the lifting plate 7. The top of the separation component 9 extends into the cavity 5. The separation component 9 includes a fixed tube 10, which is fixedly connected to the rectangular frame 6. A push rod 11 is installed in the fixed tube 10. The bottom end of the push rod 11 is fixedly connected to the lifting plate 7. After the top of the fixed tube 10 and the push rod 11 extend into the cavity 5, the top of the two is flush with the bottom of the cavity, so it will not affect the injection molding shape of the product. An air groove 12 is provided in 10, and an air inlet pipe 13 connected to the air groove 12 is installed on one side of the fixed tube 10. When in use, the upper mold 2 and the lower mold 1 are aligned and closed, and injection molding is performed in the cavity 5 through the injection hole on the upper mold 2, and finally a product 3 with an extra-long rib position is made. Then the upper mold 2 is raised and separated from the top of the product, and the electric push rod is started to shorten its output shaft, thereby driving the lifting plate 7 to descend. The lifting plate 7 descends and drives the ejector rod 11 to descend below the highest position of the top of the air groove 12, and then passes through the air groove 12, so that the air inlet pipe 13 is connected to the top pipe opening of the fixed tube 10 (the cavity 5). The bottom of the cavity 5 is connected, and then air or inert gas is injected into the bottom of the cavity 5 through the air inlet pipe 13, so that a part of the gas is filled between the product 3 and the inner wall of the cavity 5, so that the product 3 is initially separated from the cavity 5, and then the output shaft of the electric push rod is extended to lift the lifting plate 7, so that the push rod 11 is raised and its top is flush with the top of the fixed tube 10. Finally, the rectangular frame 6 is driven by the driving source to rise, and the fixed tube 10 and the push rod 11 in the fixed tube 10 are lifted, so that the product 3 is pushed out of the cavity 5 to a certain height, and the product 3 is separated from the cavity 5, which is convenient for removing the product.

[0027] By arranging a demoulding mechanism 4 including a rectangular frame 6, a lifting plate 7, an electric push rod 8 and multiple separation components 9 at the bottom of the lower mold 2, gas can be conveniently injected into the bottom of the cavity 5 to initially separate the product 3 from the cavity 5, and then the fixed tube 1 and the ejector rod 11 are lifted to eject the product 3 from the cavity 5, thereby facilitating the demoulding and unloading of the product 3.

[0028] Example 2:

[0029] like Figure 4 As shown, a plurality of sealing rings 14 are installed at the bottom end of the fixed tube 10. By using the sealing ring 14, the fixed tube 10 is slidably sealed between the lower end outlet and the ejector rod 11 to prevent gas leakage from the bottom end of the fixed tube 10. Similarly, a sealing ring 14 can also be installed at the top end of the fixed tube 10. This embodiment only takes the installation of the sealing ring 14 at the bottom end of the fixed tube 10 as an example for explanation. When in use, after the high-pressure gas in the air inlet pipe 13 enters the air groove 12, some of the gas will advance toward the two ends of the fixed tube 10 along the tiny gap between the fixed tube 10 and the ejector rod 11. Due to the sealing of the sealing ring 14 at the lower end of the fixed tube 10, the gas cannot pass through, thereby achieving a sealing effect, preventing gas leakage, which causes the pressure in the cavity 5 to decrease.

[0030] By installing a sealing ring 14 at the bottom end of the fixed tube 10 , the fixed tube 10 and the top rod 11 can be sealed to prevent gas leakage.

[0031] Example 3:

[0032] like Figure 2 As shown, an air supply pipe 15 is installed on the top of the rectangular frame 6, and the two ends of the air supply pipe 15 are respectively connected to the high-pressure gas source and the air intake pipe 13. When in use, the high-pressure gas source provides high-pressure gas, and the high-pressure gas can enter the air intake pipe 13 through the air supply pipe 15, thereby facilitating the centralized air supply to each separation component 9.

[0033] By installing the air supply pipe 15 on the top of the rectangular frame 6 , it is possible to conveniently and centrally supply air to the separation assembly 9 .

[0034] Example 4:

[0035] like Figure 2 As shown, a plurality of limit plates 16 are installed on the top of the lifting plate 7. When in use, when the lifting plate 7 is raised, the limit plates 16 are driven to rise and abut against the top of the rectangular frame 6. The lifting plate 7 cannot continue to rise, and the lifting plate 7 is limited. At this time, the top of the push rod 11 is flush with the top of the fixed tube 10.

[0036] By installing a plurality of limiting plates 16 on the top of the lifting plate 7 , the lifting plate 7 can be conveniently limited so that the top of the push rod 11 is flush with the top of the fixed tube 10 .

[0037] Example 5:

[0038] like Figure 1 As shown, a plurality of positioning holes are provided on the edge of the upper mold 2, and correspondingly, a plurality of positioning columns are installed on the lower mold 1. When the mold is closed, the positioning columns pass through the positioning holes, so that the upper mold 2 and the lower mold 1 can be accurately closed to prevent misalignment.

[0039] By installing a positioning column on the lower mold 1 and opening a positioning hole on the upper mold 2, the upper mold 2 and the lower mold 1 can be more accurately closed.

[0040] Working principle: When in use, the upper mold 2 is aligned with the lower mold 1 and the mold is closed, and the injection molding is performed into the cavity 5 through the injection hole on the upper mold 2, and finally a product 3 with an extra-long rib is made. Then the upper mold 2 is raised and separated from the top of the product, and the electric push rod is started to shorten its output shaft, thereby driving the lifting plate 7 to descend. The lowering of the lifting plate 7 drives the ejector rod 11 to descend below the highest position of the top of the air groove 12, and then through the air groove 12, the air inlet pipe 13 is connected to the top pipe opening of the fixed pipe 10 (the bottom of the cavity 5), and then the air is pushed to the upper mold 2 through the air inlet pipe 13. Air or inert gas is injected into the bottom of the cavity 5 so that a portion of gas is filled between the product 3 and the inner wall of the cavity 5, so that the product 3 is initially separated from the cavity 5. Then the output shaft of the electric push rod is extended to lift the lifting plate 7, so that the push rod 11 is raised and its top is flush with the top of the fixed tube 10. Finally, the rectangular frame 6 is raised under the drive of the driving source, and the fixed tube 10 and the push rod 11 in the fixed tube 10 are lifted, thereby pushing the product 3 out of the cavity 5 to a certain height, separating the product 3 from the cavity 5, and facilitating the removal of the product.
