AI Technical Summary
Traditional molds suffer from problems such as insufficient parting surface fit accuracy, difficulty in selecting gate location, and improper demolding mechanism design when molding thin-walled, complex, and symmetrical UFO products, resulting in flash, gate marks, and product deformation.
The push block is fitted outside the front mold core to achieve precise centering and stable support of the front and rear mold cores. The hot nozzle of the needle valve, which runs through the front mold core, and the hot nozzle needle driven by the needle valve cylinder are used for center injection of glue to ensure the parting surface accuracy and surface smoothness.
It effectively suppresses the formation of flash, ensuring high-precision molding and surface finish of the UFO cavity, and meeting the aesthetic requirements of UFO products.

Abstract
Claims
1. A flying disc mold, characterized by, include: Rear mold push rod (1); The rear mold core (2) is disposed at one end of the rear mold push rod (1); The front mold core (4) is located at the axial end of the rear mold core (2) and, when combined with the rear mold core (2), forms a mold compartment with a flying saucer-shaped cavity. Push block (3) is fitted outside the front mold core (4) and located at the interface between the front mold core (4) and the rear mold core (2) for precise positioning of the front mold core (4) and the rear mold core (2) to form a mold chamber; A needle valve hot nozzle (5) is disposed inside the front mold core (4); A hot nozzle valve needle (6) is coaxially disposed inside the needle valve hot nozzle (5), with one end extending to the inlet of the mold chamber; The needle valve cylinder (7) is driven to the other end of the hot nozzle valve needle (6) and is used to control the opening and closing movement of the hot nozzle valve needle (6).
2. The flying disc of claim 1, wherein: The rear mold core (2) and the rear mold push rod (1) are rigidly connected by threads.
3. The flying disc of claim 2, wherein: The rear mold core (2) has a positioning step (21) on its axial end face that connects with the push block (3).
4. The flying disc of claim 3, wherein: The annular inner wall of the push block (3) is fitted with the outer wall of the front mold core (4) with a clearance, and the front mold core (4) is provided with a blocking step (41) for blocking the push block (3).
