Detailed Description of the Invention

[0023] The following are specific embodiments of the present invention in combination with the drawings, and the technical solutions of the present invention will be further described. However, the present invention is not limited to these embodiments.

[0024] A combined core-pulling structure for the upper cover of a vehicle water storage bottle, as Figures 1 to 5 shown, includes a driving member 1, a core-pulling slider one 2, and a core-pulling slider two 3.

[0025] The core-pulling slider one 2 is adapted to the outer surface of the upper cover and the inner surface of the liquid return pipe, and the core-pulling slider two 3 is adapted to the outer surface of the liquid return pipe and the outer surface of the undercut structure.

[0026] The output end of the driving member 1 is connected to the core-pulling slider one 2. The core-pulling slider one 2 is slidably arranged on the lower mold (not shown in the figure). Preferably, the driving member 1 is an oil cylinder. The driving member 1 is used to drive the core-pulling slider one 2 to approach or move away from the upper cover, so that the core-pulling slider one 2 is disengaged from the outer surface of the upper cover and the inner surface of the liquid return pipe.

[0027] The core-pulling slider two 3 is slidably arranged on the core-pulling slider one 2. An inclined guide post 4 is slidably arranged on the core-pulling slider two 3. A guide hole 5 is inclinedly formed on the core-pulling slider two 3. The inclined guide post 4 is slidably arranged in the guide hole 5. The inclined guide post 4 is connected to the upper die. Specifically, the inclined guide post 4 and the upper die (not shown in the figure) are connected through a connecting block 8. A counterbore 9 is formed on the connecting block 8. The inclined guide post 4 passes through the counterbore 9. A limiting head 10 is provided on the inclined guide post 4. The limiting head 10 abuts against the connecting block 8, that is, the limiting head 10 cannot pass through the counterbore 9. The connecting block 8 is connected to the upper die through bolts.

[0028] An avoidance groove 18 for avoiding the inclined guide post 4 is formed on the core-pulling slider one 2 to avoid the inclined guide post 4.

[0029] The upper die can drive the core-pulling slider two 3 to approach or move away from the liquid return pipe through the inclined guide post 4. Specifically, when the upper die separates, the inclined guide post 4 slides along the guide hole 5. The upper die drives the core-pulling slider two 3 to move away from the liquid return pipe through the inclined guide post 4. The core-pulling slider two 3 is separated from the outer surface of the liquid return pipe and the outer surface of the undercut structure.

[0030] A guide strip 6 is arranged on the core-pulling slider one 2. A guide groove 7 is formed on the core-pulling slider two 3. The guide strip 6 and the guide groove 7 are in sliding fit. The core-pulling slider two 3 is guided through the cooperation of the guide strip 6 and the guide groove 7, so that the core-pulling slider two 3 slides more smoothly.

[0031] A limiting member 11 for limiting the core-pulling slider two 3 is arranged on the core-pulling slider one 2. The limiting member 11 includes a limiting bolt. The limiting bolt is threadedly connected to the core-pulling slider one 2. When the core-pulling slider two 3 slides, the outer surface of the limiting member 11 can abut against the outer surface of the core-pulling slider two 3 to limit the core-pulling slider two 3.

[0032] The core-pulling structure further includes a first limiting block 13 for limiting the core-pulling slider one 2. The first limiting block 13 is installed on the lower die through bolts, so as to facilitate the disassembly, installation and replacement of the first limiting block 13. A first limiting step 12 is arranged on the core-pulling slider one 2. The lower surface of the first limiting block 13 abuts against the step surface of the first limiting step 12 to ensure the stability of the core-pulling slider one 2 during sliding.

[0033] A second limiting block 14 for limiting the core-pulling slider two 3 is detachably connected to the core-pulling slider one 2. The second limiting block 14 is connected to the core-pulling slider one 2 through bolts, so as to facilitate the disassembly, installation and replacement of the second limiting block 14. A second limiting step 15 is arranged on the core-pulling slider two 3. The lower surface of the second limiting block 14 abuts against the step surface of the second limiting step 15.

[0034] A positioning post 16 is provided on the core-pulling slider 1. A positioning groove 17 is formed on the core-pulling slider 2. When the core-pulling slider 2 slides, the positioning post 16 can be inserted into or disengaged from the positioning groove 17. In the normal state, the positioning post 16 is inserted into the positioning groove 17, and the stability of the core-pulling slider 2 is ensured by the cooperation of the positioning post 16 and the positioning groove 17. During core-pulling, the positioning post 16 is disengaged from the positioning groove 17 by the sliding of the core-pulling slider 2.

[0035] As another solution, a shock-absorbing block is provided at the end of the positioning post 16. The shock-absorbing block is made of rubber material. By contacting the bottom of the positioning groove 17 with the shock-absorbing block, the vibration is reduced and the noise is decreased.

[0036] The working principle of the present utility model is as follows: First, through the separation of the upper die, the inclined guide post 4 slides along the guide hole 5. The upper die drives the core-pulling slider 2 away from the liquid return pipe through the inclined guide post 4. The core-pulling slider 2 is disengaged from the outer surface of the liquid return pipe and the outer surface of the undercut structure. Then, the driving member 1 drives the core-pulling slider 1 away from the upper cover, and the core-pulling slider 1 is disengaged from the outer surface of the upper cover and the inner surface of the liquid return pipe, thereby completing the core-pulling.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present utility model; those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
