Description

Integrated high-pressure casting die for new energy automobile workpiece Technical Field The utility model belongs to the field of die casting technology, and particularly relates to an integrated high-pressure casting die for a new energy automobile workpiece. Background With the rapid development of the new energy automobile industry, the integrated casting technology has become an important development direction in the automobile manufacturing field because the integrated casting technology can remarkably reduce the number of parts, reduce the weight of an automobile body and improve the production efficiency. In the production process of integrated workpieces of new energy automobiles, a casting die is key equipment for determining product quality and forming efficiency. In the existing integrated workpiece of the new energy automobile, a first hole-shaped structure and a second hole-shaped structure (for example, a through or semi-through coaxial mounting hole, a positioning hole and the like) which are coaxially and oppositely arranged are often designed. For such workpieces having coaxial opposed bore structures, two separate cores are typically employed in the prior art for forming each. Specifically, the first core and the second core are required to be provided, and the first hole structure and the second hole structure are required to be formed by independent operations in different driving mechanisms or core pulling directions. However, this prior art technique employing dual independent cores suffers from the following major drawbacks: the die structure is complicated, and independent driving assemblies, guide mechanisms and control systems are required to be respectively configured for the two cores, so that the internal space layout of the die is crowded, and the structural design is complicated. The coaxiality is difficult to ensure, and as the two cores independently move, the two cores are influenced by machining errors, assembly errors and motion accumulation errors, the two hole-shaped structures are difficult to ensure to have extremely high coaxiality after being molded, and subsequent assembly difficulties or product rejection are easy to cause. The die has the advantages of high production cost, low efficiency, complex structure, increased manufacturing cost and maintenance difficulty of the die, and multiple independent core pulling actions, prolonged die opening and closing period and reduced production efficiency. The space occupation is large, and the independent driving mechanism occupies precious space of a movable die or a fixed die, so that the optimal layout of the die on other functional modules (such as a cooling system and an ejection system) is limited. Disclosure of utility model Aiming at the defects in the prior art, the utility model aims to solve the technical problems that an integrated high-pressure casting die for a new energy automobile workpiece is provided, and a first hole-shaped structure and a second hole-shaped structure which are coaxially opposite on a workpiece are formed simultaneously through moving a core arranged in a core assembly, so that 'one-time core insertion forming double holes and one-time core withdrawal completion double-hole core pulling' are realized. The utility model solves the technical problem by adopting the technical scheme that an integrated high-pressure casting die for a new energy automobile workpiece is provided, the workpiece is provided with a first hole-shaped structure and a second hole-shaped structure which are coaxially and oppositely arranged, and the casting die comprises: the fixed die assembly is provided with a fixed die core block; The movable mold assembly is provided with a movable mold core block, and the movable mold core block is movably abutted against the fixed mold core block and is used for jointly forming a product cavity; a core assembly disposed on the movable mold assembly and having a movably disposed core; When the fixed die assembly and the movable die assembly are in a die closing state, the core moves along a direction perpendicular to the die closing direction and penetrates through the movable die core block to extend into the product cavity, so that the first hole-shaped structure and the second hole-shaped structure can be formed simultaneously; Before the fixed die assembly and the movable die assembly are opened, the core is withdrawn from the product cavity and used for completing core pulling action. In the integrated high-pressure casting mold for the new energy automobile workpiece, the movable mold core block is provided with the guide channel, and one end of the mold core penetrates through the guide channel and extends to the product cavity. In the integrated high-pressure casting mold for the new energy automobile workpiece, the movable mold core block is provided with the first groove structure, the fixed mold core block is provided with the corresponding second groove structure,
