Description

Technical Field

[0001] The utility model relates to the field of demoulding of silicone products, in particular to a rotary demoulding device for silicone products with internal threads. Background Art

[0002] Silica gel is a highly active adsorption material with good elasticity, stability, chemical stability, and resistance to high and low temperatures. Therefore, it is widely used in the food and medical industries.

[0003] Silicone can be processed into products of various shapes, such as silicone nipples, silicone buttons, etc. It can also be processed into silicone products with internal threads (such as Figure 1 and Figure 2 ), this kind of silicone product with internal thread will remain in the lower mold core after the production mold is opened (such as Figure 3 and Figure 4 ), due to the natural reaction of silicone material expansion and contraction, the "thread" structure inside the silicone product will wrap the lower mold core tightly. If manual demoulding is used, workers' hands are prone to soreness / tiredness, and the labor intensity is high; and manual demoulding takes a long time, the mold temperature is easy to lose, and it needs to be re-insulated, and the demoulding efficiency is extremely low. (The silicone mold temperature requires 140 degrees to 160 degrees). Utility Model Content

[0008] Furthermore, the cross section of the perforation is a cone that is smaller at the top and larger at the bottom, and the inner wall of the perforation has grooves evenly distributed around the circumference.

[0009] Furthermore, a positioning guide column is also provided on the bottom surface of the positioning stripping plate.

[0010] Furthermore, handles are provided on both sides of the top surface of the positioning stripping plate.

[0011] The beneficial effects of the utility model are:

[0012] First: Using an electric screwdriver and demoulding components can quickly demould, save time and effort, and be highly efficient.

[0013] Second: The positioning stripping plate can be quickly installed on the lower template using the positioning guide pins.

[0014] Third: A protective sleeve is set in the demoulding component. On the one hand, it guides the rotating sleeve. On the other hand, lubricating oil is applied between the protective sleeve and the rotating sleeve to achieve a lubricating effect. BRIEF DESCRIPTION OF THE DRAWINGS
