These structures are not easy to be directly demolded after being formed in the mold. Therefore, when designing the mold, it is necessary to consider the demolding problems of these special structures, and the core pulling mechanism emerges as the times require. The mold core pulling mechanism can automatically complete the demolding process of the product, reducing the time and cost of manual operation and improving the production efficiency. Especially in the case of mass production, the advantages of the mold core pulling mechanism are more obvious. After the mold core is pulled out, it is necessary to use a spray system for spraying to achieve the purposes of cooling, lubricating, demolding, etc. However, when performing the spraying operation after core pulling, an additional device is needed for operation, which not only increases the floor area but also increases the labor intensity of the staff, and the practicability is insufficient.

After the core main body 2 is pulled out, the second connecting rod 9 will be used to push the first connecting rod 8 to turn on the rotary switches of the first spray main body 6 and the second spray main body 7.
[0022] The first spray body 6 and the second spray body 7 have the same composition structure, and the first spray body 6 and the second spray body 7 are symmetrically distributed about the center of the collection box 5. A support platform 11 is provided on the lower walls of the first spray body 6 and the second spray body 7. The lower end of the rotary switch is fixedly connected to a control push rod 10. The outer wall of the control push rod 10 is slidably connected to an annular groove 12 opened on the upper wall of the collection box 5.
