[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] This utility model provides a mold inclined ejection structure, such as Figure 1-4 As shown, the inclined ejection structure of the mold includes a base 1, with side brackets 2 fixedly installed at both ends of the base 1, and a shaping mold 3 fixedly installed at the upper ends of the two sets of side brackets 2. A first ejection plate 4 is fixedly installed on the upper side of the base 1, and a second ejection plate 5 is installed between the two sets of side brackets 2. Guide pillars 11 are fixedly installed on both the left and right sides of the shaping mold 3, and connecting seats 12 are fixedly installed on both the front and rear sides of the first ejection plate 4. The lower ends of the two sets of guide pillars 11 are movably inserted into the two sets of connecting seats 12. An inclined ejection assembly for product ejection is provided between the base 1 and the shaping mold 3.

[0024] An external electric push rod drives the first ejector plate 4 and the second ejector plate 5 to rise and move. The rise of the first ejector plate 4 and the second ejector plate 5 drives the inclined ejector assembly to rise, thereby ejecting the product and ensuring the stability and reliability of the ejection process.

[0025] The inclined ejector assembly includes a straight ejector fixing rod 6, which is fixedly installed inside the first ejector plate 4. A straight ejector connecting rod 7 is installed inside the second ejector plate 5. A straight ejector insert 8 is fixedly installed at the upper end of the straight ejector connecting rod 7. Multiple sets of inclined ejector seats 9 are fixedly installed inside the first ejector plate 4. An inclined ejector rod 10 is installed at the upper end of each set of inclined ejector seats 9. The upper ends of the multiple sets of inclined ejector rods 10 are connected by the straight ejector insert 8.

[0026] When the external electric push rod continues to push, the first ejector plate 4 and the second ejector plate 5 rise, causing the straight push fixing rod 6, the straight push connecting rod 7, the straight push insert 8, the multiple sets of inclined push seats 9 and the multiple sets of inclined push rods 10 to move upward, thereby smoothly ejecting the product at an angle.

[0027] The two sets of connecting seats 12 each have a groove 13 on one side opposite to each other, and the second top plate 5 has movable grooves 14 at both ends. Limiting blocks 15 are installed in both sets of movable grooves 14.

[0028] When the first ejector plate 4 and the second ejector plate 5 rise, the two sets of guide columns 11 are inserted into the two sets of connecting seats 12 as the first ejector plate 4 and the second ejector plate 5 rise. The two sets of guide columns 11 also press the two sets of limiting blocks 15 into the two sets of movable grooves 14, so that the second ejector plate 5 continues to rise, driving the straight-push fixing rod 6, the straight-push connecting rod 7 and the straight-push insert 8 to eject the product a second time.

[0029] The lower ends of the two sets of guide columns 11 and the side of the two sets of limit blocks 15 that are close to each other are both set with slopes.

[0030] The inclined surface design allows the two sets of guide pillars 11 to push the two sets of limit blocks 15 into the two sets of movable slots 14 more smoothly when they are inserted into the two sets of connecting seats 12. This ensures that the ejection process of the inclined ejector assembly is more stable and smooth, avoids damage to the product, and improves the ejection efficiency and quality of the product.

[0031] Each of the two sets of movable slots 14 is equipped with a return spring 16, and the return spring 16 in the two sets of movable slots 14 is connected to the limit block 15 installed in the two sets of movable slots 14.

[0032] The reset spring 16 is used to limit and guide the limit block 15, ensuring that the two sets of limit blocks 15 slide stably in the two sets of movable grooves 14, and can ensure that the two sets of limit blocks 15 slide and reset in the two sets of movable grooves 14, further improving the ejection stability and reliability of the inclined top assembly.

[0033] The lower ends of the two sets of side supports 2 are concave on opposite sides, and the distance between the lower ends of the two sets of side supports 2 is the same as the width of the first top plate 4.

[0034] When the first ejector plate 4 slides upward, the distance between the lower ends of the two sets of side supports 2 is used to prevent the first ejector plate 4 from rising too high, thus ensuring the stability and reliability of the inclined ejector assembly during the ejection process.

[0035] Working principle: During use, the external electric push rod pushes the first ejector plate 4 and the second ejector plate 5 to rise. The rise of the first ejector plate 4 and the second ejector plate 5 drives the straight-push fixing rod 6, the straight-push connecting rod 7, the straight-push insert 8, the multiple sets of inclined ejector seats 9 and the multiple sets of inclined ejector rods 10 to move upward, thus ejecting the product for the first time. When the external electric push rod continues to push, the two sets of guide columns 11 are inserted into the two sets of connecting seats 12 as the first ejector plate 4 and the second ejector plate 5 rise. The inclined surfaces of the two sets of guide columns 11 press and slide the two sets of limiting blocks 15 into the two sets of movable grooves 14, so that the second ejector plate 5 continues to rise, driving the straight-push fixing rod 6, the straight-push connecting rod 7 and the straight-push insert 8 to eject the product for the second time. The entire device realizes the inclined ejection of the product, effectively avoiding the product deformation and scratches that may be caused by the traditional straight ejection method, and improving the ejection quality and efficiency of the product.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
