Multi-direction step-by-step tridimensional punching method of IML products and punching mould thereof

Abstract

The invention relates to a multi-direction step-by-step tridimensional punching method of IML products and a punching mould thereof, which is characterized in that a punching mould combing a direct punching mould and a lateral punching mould is adopted to dimensionally punch the cavern shapes and edge contours of IML product located on different surfaces step by step; the punching mould comprises an upper mould which comprises a punch (straight punching head) and a lower mould which comprises a die and air cylinder side cut assemblies; the punch of the upper mould and the die of the lower mould form a straight punching mode; the side wall of the die and four groups of air cylinder side cut assemblies of the lower mould form a side punching mode; a multidirectional step-by-step dimensional method is adopted to decompose the punching of the IML product with complex structure and shape into one-step punching with simpler shape, the power of one-step punching of side faces is provided by a straight air cylinder, thereby ensuring the quality and stability of quenching; in addition, the punching method has simple operation and accurate production orientation, the qualification rate can be above 90%, therefore, the method is applicable to large-scale batch production.

Description

technical field [0001] The invention relates to a three-dimensional IML product punching method, in particular to a multi-directional, step-by-step, three-dimensional punching method and a punching die for an IML product that is used for processing IML product workpieces with complex structures and thicker material to be punched. . Background technique [0002] The punching of complex structure IML product workpieces and IML product workpieces with thicker materials has high requirements for punching dies. When the side wall of the punched product has holes or the wall thickness is greater than 0.4mm, the difficulty of punching will increase a lot. When the existing direct punching technology deals with this problem, it usually cannot punch out the holes on the side wall or cannot meet the appearance requirements of thicker IML products due to the wider section after punching. The urgent needs of the complex structure (for example: the side wall has holes) IML product proce...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art. The existing direct punching technology cannot punch out the holes on the side wall of the punched product or cannot meet the appearance of thicker IML products due to the wide section after punching. The requested problem is to provide a method for cutting complex structure IML products and thicker IML products from multi-directional, step-by-step, three-dimensional
