Description

[Technical Field]

[0001] This utility model relates to a sloping top structure for a mold. [Background Technology]

[0002] In mold design, the design of the angled ejector plays a crucial role. It not only effectively prevents jamming between the mold and the product, ensuring smooth demolding, but also significantly shortens mold opening time and improves overall production efficiency by optimizing the mold opening and closing process. Furthermore, the angled ejector design reduces pressure and friction on the product, thereby reducing surface defects and improving product quality. Simultaneously, it reduces mold wear, extends mold life, and lowers maintenance and replacement costs. In conclusion, the angled ejector design provides multiple practical benefits in mold design, including improved production efficiency, reduced costs, and guaranteed product quality, making it an indispensable element in mold design.

[0003] However, when the existing inclined ejector is ejected, the force direction of the inclined ejector rod is not along the axial direction of the inclined ejector rod, which makes it easy for the force point to deviate when pushing the product. This utility model is to solve the above-mentioned technical problem. [Summary of the Invention]

[0015] This invention features a pair of symmetrically arranged grooves on a slanted push base, within which a pair of sliders are mounted. A universal joint for the slanted push rod is movably connected between these sliders, and the rear end of the slanted push rod is connected to the universal joint. When the slanted push base is pushed, it causes the slanted push rod and the slanted push rod to move upwards, while the sliders move simultaneously. The universal joint automatically adjusts to ensure the slanted push rod moves along its axial direction. The structure is simple, the thrust is uniform, the force point does not shift, and the force on the slanted push rod is always along its axial direction. [Attached Image Description]
