Solidification glue band is in long strip, and interval is laid on upper surface layer or undersurface layer.
Existing die cutting die all uses cutting insert mouth on mold to be punched out, due to the punching edge of a knife and knife of existing die cutting die
In step-like (as shown in Figure 1, 2, 3) between mouthful, the distance between the edge of a knife and product are inconsistent, and the product being punched into is in the edge of a knife
The place to connect has the trace for connecing knife, and the step-like edge of a knife is not while being punched out with product contact in blanking process, produces
Product some places first contact the edge of a knife, and some places are followed by contact knife mouth, and the discontinuity in blanking process causes product to be rolled over
Trace influences product quality.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems and provides a kind of enhanced automobile car roof soundproof pad punching
Cutting apparatus solves to generate creasing problem because of blade unbalance stress.
The purpose of this utility model is achieved through the following technical solutions:
A kind of enhanced automobile car roof soundproof pad blanking units, including lower die and upper mold, the lower die include lower die mould bases,
Lower die mold core and piercing tip, the upper mold include and the matched upper mold mould bases of the lower die mould bases and the lower die mold core
The upper mould core matched and with the matched upper punch incisal guide slot of the piercing tip, the edge of a knife of the piercing tip be and roof every
The arcuate structure that matches of shape contour of sound pad product, the punching edge of a knife can guarantee the edge of a knife be punched oral area to product type face away from
From being consistent, in this way in product blanking process, product with knife edge contact be it is synchronous, be punched no sequencing, product
Uniform force will not generate creasing problem because of unbalance stress.
Further, the piercing tip is integrally disposed upon the periphery of lower die mold core, and a line only installs a punching cutter
Mouthful, instead of original step-like a plurality of edge of a knife, installed when making mold more convenient.
Further, the piercing tip is fixed on piercing edge by the knife locking block being set on lower die mould bases.
Further, the lower die mould bases and upper mold mould bases are rectangle cast iron frame structure.
Further, the quadrangle of the lower die mould bases is equipped with guide-post of die-set, the quadrangle of the upper mold mould bases be equipped with it is described
Molding is completed in the matched mold guide sleeve of guide-post of die-set, guide-post of die-set and mold guide sleeve cooperation.
Further, the lower die mold core is elastic mold core.
Further, the lower die mold core is equipped with mandril.
Compared with prior art, this enhanced automobile car roof soundproof pad blanking units are by existing in step-like punching cutter
Mouth replaces with the arcuate structure to match with the shape contour of car roof soundproof pad product, which can guarantee the edge of a knife
The distance in punching oral area to product type face is consistent, and in this way in product blanking process, product and knife edge contact are to connect simultaneously
Touching, is punched no sequencing, product uniform force solves the creasing problem generated by unbalance stress.A line is only pacified
A novel punching cutter mouth is filled, solves and generates the lapping defect being punched between the edge of a knife due to limitation of shape need to install multiple old-fashioned edges of a knife
It is neat and artistic to be punched into the product edge come for problem.Mold a line only needs to install an edge of a knife, instead of original step-like more
The edge of a knife, is installed more convenient when making mold.
