[0026] The present utility model will be described in detail below with reference to the accompanying drawings.

[0027] As Figures 1-3 shown, the double - moving - position insert - mold - out structure includes an upper mold core 1, a side mold core plate 2, and a right - moving position plate 21. An upper moving position block 13 is installed on the upper mold core 1, a horizontal forming rod 22 is installed on the side mold core plate 2, and a horizontal moving position rod 23 is installed on the right - moving position plate 21. A demolding ejector pin 27 that is horizontally aligned with the product 18 is further provided outside the side mold core plate 2, and the side mold core plate 2 is provided with an ejector pin hole 28 through which the demolding ejector pin 27 moves. The upper moving position block 13 moves longitudinally, and the horizontal moving position rod 23 moves horizontally.

[0028] When closing the mold, the upper mold core 1 approaches the mold cavity, so that the bottom end of the upper moving position block 13 is located in the mold cavity; the right - moving position plate 21 approaches the mold cavity, and in cooperation with the horizontal forming rod 22 and the horizontal moving position rod 23, it is convenient for the product 18 to be injection - molded. When demolding, the right - moving position plate 21 moves away from the mold cavity, and then the upper mold core 1 moves away from the mold cavity as a whole; the demolding ejector pin 27 passes through the ejector pin hole 28 of the side mold core plate 2 to eject the product 18 from the side mold core plate 2, realizing demolding; adopting the double - moving - position structure, the cost during injection molding is reduced, and the efficiency during demolding is higher.

[0029] The upper mold core 1 is provided with a first moving - position groove 11 for installing the upper moving position block 13, and the upper moving position block 13 is movably installed in the first moving - position groove 11; according to the shape of the product 18, the upper moving position block 13 can be taken out from the first moving - position groove 11 and replaced with an upper moving position block 13 with a different mold - core shape, further improving the practicability.

[0030] Preferably, a limiting groove 12 is formed at the top of the first moving - position groove 11, and a limiting block 14 that cooperates with the limiting groove 12 is formed at the top of the upper moving position block 13. The limiting block 14 is in a stop - fit with the first moving - position groove 11 to prevent the upper moving position block 13 from falling out of the first moving - position groove 11; when demolding, the upper mold core 1 rises. Due to the stop - fit between the limiting block 14 and the first moving - position groove 11, the upper moving position block 13 moves away from the mold cavity simultaneously and disengages from the product 18, ensuring that the product 18 can be demolded quickly.

[0031] Furthermore, a top - forming rod 15 for forming a hole position is installed at the bottom of the upper moving position block 13; through the top - forming rod 15, the product 18 can form a hole position at the top.

[0032] Furthermore, the moving direction of the upper mold core 1 is perpendicular to the moving direction of the side mold core plate 2; during demolding, the upper mold core 1 will not collide with the side mold core plate 2 and the right moving plate 21, thus ensuring the stability during demolding.

[0033] A ejector plate 25 for installing demolding ejector pins 27 and a demolding drive plate 26 for driving the ejector plate 25 to approach or move away from the side mold core plate 2 are arranged outside the side mold core plate 2. After the upper mold core 1 and the right moving plate 21 move away from the mold cavity, if the product 18 adheres to the side mold core plate 2, at this time, the demolding drive plate 26 is moved horizontally to drive the demolding ejector pins 27 installed on the ejector plate 25 to pass through the moving holes of the side mold core plate 2 to eject the product 18 from the mold cavity, realizing demolding.

[0034] A side mounting plate 24 is further installed outside the side mold core plate 2. The side mounting plate 24 is connected to the side mold core plate 2, and the side mold core plate 2 is fixedly installed through the side mounting plate 24.

[0035] In one embodiment, a bottom forming plate 16 is formed at the bottom of the upper moving block 13. A guiding hole 17 is formed horizontally through the bottom forming plate 16. The guiding hole 17 is coaxially aligned with the horizontal forming rod 22 and the horizontal moving rod 23 respectively, and the horizontal forming rod 22 and the horizontal moving rod 23 can be inserted into the guiding hole 17 respectively.

[0036] During mold closing, the upper moving block 13 moves longitudinally close to the mold cavity. After moving in place, the guiding hole 17 formed in the bottom forming plate 16 is coaxially aligned with the horizontal forming rod 22 and the horizontal moving rod 23; then the side mold core plate 2 and the right moving plate 21 approach each other, so that the horizontal forming rod 22 and the horizontal moving rod 23 can be inserted into the guiding hole 17 respectively, completing mold closing.

[0037] In summary, it can be seen that the present utility model has the above-mentioned excellent characteristics, enabling it to enhance the efficiency never achieved in the prior art during use and having practicality, becoming a product 18 with extremely high practical value.

[0038] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present utility model.
