[0002] To prevent rainwater from being splashed onto motorcyclists by the inertia of the wheels, mudguards have become an essential component of motorcycles. Conventional mudguard structures are injection molded and ejected by ejector pins during mold demolding. However, for mudguards with more complex structures and internal buckling features, simple ejector pins are not sufficient for demolding. A multi-slider structure is required for demolding to achieve the desired rapid demolding. Summary of the Invention

During injection molding, the side molding sliders and the front molding slider press against the outer surface of the molding module, forming the injection cavity surface. During demolding, the angled ejector rod moves obliquely inward as the upper mold base rises, disengaging from the angled ejector section. As the upper mold base rises, the side molding sliders and the front molding slider disengage from the slider baffle and side stop, allowing them to slide directly outward under the action of the cylinder. Finally, the injection molded part on the molding module is ejected directly by the ejector pin, achieving efficient demolding. Attached Figure Description

During injection molding, the side molding slider 13 and the front molding slider 9 are pressed against the outer surface and front end of the molding module 12, thereby forming a ring of injection cavity surface on the outer side of the molding module 12. After the injected plastic cools and solidifies, during demolding, the angled ejector rod 16 can move along with the mold. The upper mold base 3 rises and moves obliquely inward, causing the bottom of the inclined ejector rod 16 to disengage from the inclined ejector demolding part 17 without affecting the demolding of the embedded inclined ejector demolding part 17. As the upper mold base 3 rises, the slider baffle 10 and the side block 14 are released from their limits, allowing the side forming slider 13 and the front forming slider 9 to slide directly outward under the drive of the cylinder. Then, the injection molded part on the molding module 12 is ejected directly by the ejector pin to achieve demolding. The entire demolding process is simple and efficient.
