Inner core pulling and cooperative ejection demolding structure of grating product mold

Abstract

The invention provides an inner core pulling and cooperative ejection demolding structure of a grating product mold, a mold cavity is arranged in a forming mold, the mold cavity is separated into an upper mold part and a lower mold part by a parting surface, and a radar hole inner core pulling synchronous ejection structure, an edge straight ejection structure and a grating inclined ejection structure are arranged in the lower mold part; the radar hole inner core-pulling synchronous ejection structure comprises an inner core-pulling block capable of moving downwards, the upper portion of the inner core-pulling block is a forming face for forming a radar hole structure, an inclined ejection body is obliquely arranged in the inner core-pulling block in a penetrating mode, a through hole forming face is formed in the inclined ejection body, and the horizontal height of the inclined ejection body is relatively unchanged. And the inner core-pulling block is ejected out of the inner core-pulling block in the downward moving process of the inner core-pulling block. According to the scheme, the demolding efficiency is improved, collision damage and pulling damage in the forming process are avoided, the product quality is improved, machining defects are avoided, the service life of a product is prolonged, the working efficiency of mold equipment is high, the maintenance cost is reduced, and the economic benefits are improved.

Description

technical field [0001] The invention relates to a high-efficiency molding and demoulding working structure of a bumper grille forming mold, in particular to a demoulding structure of inner core-pulling and cooperative ejection of a grille product mold. Background technique [0002] The front bumper grille of a car is a structure that guides the air at the front of the car. In the front of the car is the engine compartment. The water tank and engine heat dissipation of the car need to use flowing air, and the air conditioning system also needs to be ventilated. structure, and the hollow structure of the bumper grille helps the airflow at the front of the car to enter the engine compartment. With the development of technology in the automotive industry, the number of auxiliary functions integrated in the car has increased, and the radar auxiliary device is used to help the driver perceive the car. The distance between surrounding objects improves the safety of driving and prov...

[0003] In addition, the bumper grille is a kind of flat structure, and the outer edge is a frame structure with a fixed overall shape. On the edge of the outer frame, there are evenly and regularly distributed buckle structures, and the buckle structure integrates the whole bumper grille It is fixed on the front bumper structure. The middle part of the bumper grille is a hollowed-out grille structure. The strength of the grille structure is weak. If the thrust is uneven during demoulding, it will cause deformation of the grille structure and affect the quality of the product. quality
