Description
Technical field
The invention belongs to plastic compression mould manufacturing technology field is and in particular to a kind of plastic mold for miniature electronic fuse part
Tool.
Background technology
Miniature electronic fuse assembly is the core component of certain kind equipment, with electronization, digitized, wireless communication technique
Development, this kind of part increasingly develops to miniature, high-accuracy, high reliability direction, and its planform also becomes increasingly complex, related
Mould design and fabrication technology also become to become increasingly complex, be primarily present following problem：(1) traditional teaching material,
The plastic compression mould structure that Specialty Design tool data, atlas case are introduced, after part plastic pressure forming, will using the push pedal on mould
Plastic pressuring piece is released from core, completes plastic pressuring piece demoulding from core, but this mould structure needs during plastic compression part
Repeatedly load and unload push pedal, cause colliding with and wearing and tearing of push pedal and core, in the life-span of reduction mould, push pedal makes in cargo handling process repeatedly
Production efficiency reduces, and plastic pressuring piece compact dimensions precision is low, and size is unstable；(2), in traditional mold cores edging method, mould
In casting die, circular port is typically shaped with cylindrical core, and the installation circular hole of cylindrical male plug is to be easiest to process, semicircle, waist
Shape is also easily worked by wire cutting, and cylindrical, semicircle, Kidney core mold insert is core designs method the most general.But it is right
For the X-type core mold insert in electronic fuse assembly, it will be divided into several sections, individually make, be separated
Mold insert easily makes, but can form sharp angles edge in X-type wire film trap mold insert with circular, round waist type mold insert mosaic position
Spell, mold polish, the angle of collapsing of polishing appearance, the mosaic of wedge angle position, assembling occur big gap, cause plastic pressuring piece outward appearance burr
Many, corner collapse angle not back chipping, that splicing seams are many, outward appearance is coarse, lug plate trench bottom out-of-flatness and dimensional accuracy are difficult to ensure that etc. is all
Many defects；(3) mold cores and mold insert hanging platform traditional design methods are to lead directly to hanging platform, square or circle in mold insert top design
The hanging platform that the regular shapes such as shape are easily worked, the mold insert for Complex Different Shape is just difficult to, and generally adopts link plate and complexity
Core riveting, the mode of welding combine, or laterally process hole, wear straight pin as hanging platform, its shortcoming is that assembly is many, and man-hour is long, become
This height, is just more difficult to design and processing hanging platform mounting portion for complex-shaped, mosaic are intensive.Therefore it is directed to these problems to propose to change
Enter.
