Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of automobile tailgate mould lock catch seat slider linkage mould locking core-pulling mechanisms, belong to injection mould field. BACKGROUND

[0002] Injection mould is one of the commonly used appliances for producing plastic products, and its structure is designed according to the characteristics and shape of the product. Since the lock catch seat for mounting the tailgate lock catch is provided on the automobile tailgate, the lock catch seat stripping structure is also provided on the mould forming body. The lock catch seat structure of the tailgate of different vehicle models is also different. The automobile tailgate lock catch seat involved in the present application comprises a convex seat protruding upward, and an open slot is provided on the convex seat. Therefore, in addition to the design of the forming body of the mould, the stripping structure of the convex seat and the open slot also needs to be designed. The existing technology usually adopts independent stripping structure for stripping the convex seat and the open slot. For example, the oil cylinder direct pulling structure is usually adopted for the convex seat, and the inclined guide pillar outer pulling structure is usually adopted for the open slot. However, it is found in actual production that since the back of the convex seat is a deep pit, a larger injection pressure is required to meet the filling requirement. After the injection pressure is increased, a larger mould locking force is required to lock the stripping insert for stripping. The mould locking force of the oil cylinder direct pulling stripping structure is directly provided by the oil cylinder. However, the volume of the oil cylinder is limited by the internal space of the mould, and cannot be too large. Therefore, a larger volume of oil cylinder cannot be directly provided (the larger the oil cylinder, the larger the mould locking force), which causes the convex seat to be often expanded, resulting in production burrs, defects and even scrap at this position.
