[0012] The beneficial effects of this utility model are:

[0013] This utility model provides an injection mold for producing plastic cups. A base frame is used to load a connecting block. A connecting block fixedly installed on the top of the base frame supports the base frame and the loading block, and limits the loading block. A loading block fixedly installed on the top of the connecting block loads and limits an electric push rod and a sliding seat. An electric push rod fixedly installed on the top of the loading block controls the linear lifting and lowering of the top mold machine. The top mold mounted on the electric push rod presses the forming mold, thereby promoting the molding of the plastic cup. A top frame fixedly installed on the top of the top mold loads the top mold and lifts and lowers it together. After the top mold and top frame are raised, an electric guide rail drives the sliding seat to move linearly. The sliding seat moves the forming mold together, so that after the plastic cup injection is completed, the sliding seat and the forming mold move laterally with the plastic cup, exposing the plastic cup. This facilitates easy demolding of the plastic cup and improves the efficiency of plastic cup injection molding. Attached Figure Description

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-5 This utility model provides an injection mold for producing plastic cups, including a base frame 1, a connecting block 2 fixedly installed on the top of the base frame 1, a loading block 4 fixedly installed on the top of the connecting block 2, an electric push rod 5 fixedly installed on the top of the loading block 4, a top mold 6 installed on the electric push rod 5, a top frame 7 fixedly installed on the top of the top mold 6, a sliding seat 10 between the loading block 4 and the top mold 6, a forming mold 11 fixedly installed on the top of the sliding seat 10, a forming hole 15 opened on the forming mold 11, a stepping groove 19 opened on the bottom of the forming mold 11, a positioning post 20 fixedly installed on the inner side of the stepping groove 19, a sliding groove 16 opened on the bottom of the sliding seat 10, and an electric guide rail 9 that cooperates with the sliding groove 16 fixedly installed on the loading block 4 and below the sliding seat 10.

[0026] During operation, the base frame 1 is used to load the connecting block 2. The connecting block 2, which is fixedly installed on the top of the base frame 1, supports the base frame 1 and the loading block 4 and limits the loading block 4. The loading block 4, which is fixedly installed on the top of the connecting block 2, is used to load and limit the electric push rod 5 and the sliding seat 10. The electric push rod 5, which is fixedly installed on the top of the loading block 4, controls the linear lifting and lowering of the top mold 6. The top mold 6, which is installed on the electric push rod 5, is used to press the molding mold 11, thereby promoting the molding of the plastic cup. The top frame 7, which is fixedly installed on the top of the top mold 6, is used to load the top mold 6 and lift and lower it together. After the top mold 6 and the top frame 7 are lifted, the sliding seat 10 is driven to move linearly through the electric guide rail 9. The sliding seat 10 drives the molding mold 11 to move together. Thus, after the plastic cup is injected, the sliding seat 10 and the molding mold 11 pull the plastic cup horizontally together, thereby exposing the plastic cup, which is conducive to the convenient demolding of the plastic cup and improves the efficiency of plastic cup injection molding.

[0027] The sliding seat 10, located between the loading block 4 and the top mold 6, is used to load the molding mold 11 and to support and shape the mold. The molding mold 11, fixedly mounted on the top of the sliding seat 10, cooperates with the molding hole 15 on the molding mold 11 for molding the plastic cup. The stepping groove 19 on the bottom of the molding mold 11 is used to load the positioning post 20 and to lift the plastic cup. The positioning post 20, fixedly mounted on the inner side of the stepping groove 19, supports the sliding seat 10 and the molding mold 11, allowing the sliding seat 10 to drive the molding mold 11 to move laterally. The sliding groove 16 on the bottom of the sliding seat 10 is used to load the electric guide rail 9, which drives the sliding seat 10 to move horizontally. The electric guide rail 9, fixedly mounted on the loading block 4 and located below the sliding seat 10 and cooperating with the sliding groove 16, drives the movement of the sliding seat 10.

[0028] Furthermore, such as Figure 1 and Figure 5 As shown, the side of the sliding seat 10 is provided with a directional groove 14, and the top of the sliding seat 10 is provided with a circular groove 17 corresponding to the positioning post 20.

[0029] During operation, the directional groove 14 on the side of the sliding seat 10 is used to limit the sliding seat 10, ensuring that the sliding seat 10 moves smoothly when the electric guide rail 9 drives it. The circular groove 17 on the top of the sliding seat 10, which corresponds to the positioning post 20, is used to connect the positioning post 20, thereby limiting the connection between the sliding seat 10 and the molding die 11, making it easier for the two to move together.

[0030] Furthermore, such as Figure 5As shown, a bottom mold 18 corresponding to the forming hole 15 is fixedly provided on the sliding seat 10;

[0031] During operation, the bottom mold 18, which is fixed on the sliding seat 10 and corresponds to the molding hole 15, is used to limit the mouth of the plastic cup during injection molding, so as to facilitate the injection molding of the plastic cup.

[0032] Furthermore, such as Figure 3 As shown, a movable plate 3 is provided between the base frame 1 and the connecting block 2. A spring 12 and a connecting rod 13 are sequentially provided on the movable plate 3. The spring 12 and the connecting rod 13 pass through the loading block 4 and are connected to the sliding seat 10.

[0033] During operation, the movable plate 3, which is set between the base frame 1 and the connecting block 2, is used to load the spring 12 and the connecting rod 13. The spring 12 on the movable plate 3 is used to connect the sliding seat 10, so that the mouth of the plastic cup is squeezed and limited during the injection molding process. The connecting rod 13 ensures that the movable plate 3 maintains elasticity between the base frame 1 and the loading block 4. During the process of the movable plate 3 driving the sliding seat 10 to lift, the forming effect of the plastic cup is more stable, and air bubbles are prevented from forming in the plastic cup.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, a reserved hole 21 is provided on the top mold 6, and the electric push rod 5 passes through the inner side of the reserved hole 21;

[0035] During operation, the electric push rod 5 is inserted through the reserved hole 21 on the top mold 6 so that the electric push rod 5 can drive the top mold 6 and the top frame 7 to rise and fall together.

[0036] Furthermore, such as Figure 1 As shown, an injection nozzle 8 is fixedly installed on the top frame 7;

[0037] During operation, the injection nozzle 8, which is fixedly installed on the top frame 7, is used to inject the injection material.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
