Abstract

The utility model discloses a blanking die comprising an upper die and a lower die, a boss is arranged on the upper surface of the lower die and is provided with a circle angle of throat on the outer rim and a beard on the upper surface. The upper die consists of a first assembly and a second assembly serially-arranged from the top to the end and the first assembly is connected with the second assembly by a connecting piece. The second assembly corresponding to the boss of the lower die is provided with a through-hole and the lower surface of the first assembly is extended down to a drilling piece which is down through the through-hole. The blanking die further comprises a holder block the lower surface of which goes beyond the through-hole arranged in the through-hole. A through-hole is mounted extending through the holder block and the drilling piece is crossed through the through-hole of the holder block. The upper surface of the holder block is connected with the lower surface of the first die by a resilient. With the arrangement of the holder block, the [abe] is firstly pressed on the boss between knife-edge contacting with the upper die and the lower die, therefore the label and the blanking die can be applied perfectly, without any clearance and dislocation, thereby achieving precise die cutting products and increasing the merit rate after injection molding.

Description

A kind of die cutting die

Technical field

The utility model relates to a kind of die cutting die.

Background technology

The incrustation of injecting products generally is to spray paint after the plastic part injection moulding is finished at present, printing, secondary operations steps such as plating, it is bigger to it should be noted that said method expends cost, because injection moulding and secondary operations can't be finished the same time, moreover most secondary operations and injection moulding do not finish in same place, and middle cost is higher.

And the exploitation of IML (In Mold Label, in-mold label) technology has just in time overcome above shortcoming, and the IML technology mainly contains four big links: 1) pattern printing; 2) moulding; 3) die-cut; 4) injection moulding.And in die-cut process, shown in Fig. 1 to 5, counterdie 1 ' the upper surface of die cutting die is provided with boss 11 ', the shape of boss 11 ' is consistent with the profile of die-cut back label2 ', the outer rim of boss 11 ' is provided with a circle basil 111 ', this basil 111 ' is as the counterdie edge of a knife, and boss 11 ' upper surface is provided with groove 112 ', and the size of groove 112 ' goes up the diameter of circular hole 21 ' greater than die-cut back label2 '; Patrix 3 ' comprises first assembly 31 ' and second assembly of arranging in turn from top to bottom 32 ', connect by connector 33 ' between first assembly 31 ' and second assembly 32 ', second assembly 32 ' locates to be provided with through hole 321 ' corresponding to the boss 11 ' of counterdie 1 ', through hole 321 ' is complementary with boss 11 ', through hole 321 ' is as the patrix edge of a knife, first assembly, 31 ' lower surface is stretched to the lower edge punching part 311 ', punching part 311 ' passes through hole 321 ', the diameter of punching part 311 ' is identical with the diameter that die-cut back label2 ' goes up circular hole 21 ', and punching part 311 ' is used for going out this circular hole 21 ' on label.

When die-cut, earlier the label4 ' before die-cut is put well on the boss 11 ' of counterdie 1 ', patrix 3 ' is descending, behind the matched moulds, through hole 321 ' cooperates with boss 11 ', cuts off the redundance of product, the groove 112 ' of punching part 311 ' butt boss 11 ' upper surface, punching part 311 ' is gone out circular hole 21 ' on label, obtain the label2 ' after die-cut.

Because in the process of matched moulds, label often can not be well and the die cutting die applying, thereby cause the label size after die-cut inaccurate, thereby cause final injecting products bad.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the above problems, and a kind of die cutting die is provided.

The utility model realizes that the above-mentioned purpose scheme is: a kind of die cutting die, comprise counterdie and patrix, and wherein, the counterdie upper surface is provided with boss, and the outer rim of boss is provided with a circle basil, and the boss upper surface is provided with groove; Patrix comprises first assembly and second assembly of arranging in turn from top to bottom, connect by connector between first assembly and second assembly, second assembly is provided with through hole corresponding to the boss place of counterdie, through hole and boss are complementary, the first assembly lower surface is stretched to the lower edge the punching part, and the punching part passes through hole downwards; Also comprise briquetting, briquetting places in the through hole, and its lower surface exceeds through hole, runs through being provided with through hole on the briquetting, and the punching part passes the through hole on the briquetting, and the briquetting upper surface is connected with the first assembly lower surface by elastic component.

Described elastic component is a spring.

Described briquetting upper surface has keeper along the upper surface horizontal-extending of second assembly, and keeper is supported on second assembly.

Adopt the beneficial effect of above scheme:

Owing to be provided with briquetting, between the edge of a knife contact of mould up and down, earlier label is pressed together on the boss of counterdie, make the applying that label and die cutting die are intact, very close to each other and dislocation obtains the die-cut product of true-to-size, the yields after the raising injection moulding.

The specific embodiment

Embodiment, a kind of die cutting die shown in Fig. 6,7, comprises counterdie 1, patrix 3 and briquetting 5.

Wherein, counterdie 1 upper surface is provided with boss 11, and the shape of boss 11 is consistent with the profile of die-cut back label, the outer rim of boss 11 is provided with a circle basil 111, this basil 111 is as the counterdie edge of a knife, and boss 11 upper surfaces are provided with groove 112, and the size of groove 112 goes up the diameter of circular hole greater than die-cut back label.
