Abstract

The utility model proposes a kind of cutter of water dividing gap, the first arc transition is arranged in the V-shaped mouth in the top of the cutter between the bottom of V-type mouth and the both sides of V-type mouth, the straight length for the floor projection that distance is the mouth of a river is opened at the top of the V-type mouth.Have following the utility model has the advantages that during cutting the mouth of a river, the end of the two sides of the V-type mouth of cutter first contacts with the mouth of a river and is cut, then is gradually cut to the inside of V-type mouth, is gradually transitions at the top of the bottom and the mouth of a river of V-type mouth and contacts, last cutter continues to move along, and the mouth of a river is cut off.During shearing, point contact of traditional cutter first with the end of workpiece is avoided, but is cut place first most thick from the mouth of a river, the point until cutting to workpiece end avoids the stacking and deformation of excision material.

Description

A kind of cutter of water dividing gap

Technical field

The utility model belongs to the die cutting device technical field at the mouth of a river, and in particular to a kind of cutter of water dividing gap.

Background technique

Common plastic cement products in life usually carry out injection molding using mold.In machine-shaping, plastic cement products On can leave the mouth of a river, the so-called mouth of a river refers to the extra material for carrying out leaving on plastic cement products when injection molding.To ensure plastic cement The integrality of product and good appearance need the mouth of a river left cutting removal after machine-shaping.

It takes by hand that is, after injection molding currently, the mode at the removal mouth of a river mostly uses water dividing gap jig to carry out cutting operation Molding plastic cement products put it into simple water dividing gap jig and carry out cutting removal to the mouth of a river, then out of water dividing gap jig It picks up plastic cement products to launch into next process, but conventional water dividing gap has the problem of out-of-flatness is cut at the mouth of a river, or cuts After cutting the mouth of a river, surface leaves cutting trace, and it is cooling plastic cement that main cause, which is workpiece, and Inner Constitution is chill, and cutter is cut at this time The circular mouth of a river is cut, cutter first squeezes mouth of a river surface, and the material at the mouth of a river is stacked to cutter traffic direction, the fortune of cutter Row is by biggish resistance, and material of the plastics at the mouth of a river be to being squeezed and deformed everywhere, when cutter leaves, cutting of taking together Material, irregular due to deformation, the workpiece surface after leading to cutting leaves cutting trace.

Utility model content

In order to solve the above technical problems, the top of the cutter is in V the utility model proposes a kind of cutter of water dividing gap Type mouth, is arranged the first arc transition between the bottom of V-type mouth and the both sides of V-type mouth, distance is opened for institute in the top of the V-type mouth State the straight length of the floor projection at the mouth of a river.

Preferably, the second arc transition is arranged in the end of the two sides of the V-type mouth.

Preferably, straight flange is arranged in the both sides of the V-type mouth.

Preferably, third circular arc, the radius phase of the radius of the circular arc and the mouth of a river is arranged in the both sides of the V-type mouth Together.

Preferably, the chamfered transition of the side setting of the cutter diagonally downward.

Preferably, groove is arranged in the lower section of the chamfered transition.

The utility model has following the utility model has the advantages that during cutting the mouth of a river, and the end of the two sides of the V-type mouth of cutter is first It contacts and is cut with the mouth of a river, then gradually cut to the inside of V-type mouth, be gradually transitions the bottom and the mouth of a river of V type mouth Top contact, last cutter continue to move along, the mouth of a river are cut off.During shearing, avoid traditional cutter first with The point contact of the end of workpiece, but cut place first most thick from the mouth of a river, the point until cutting to workpiece end avoids The stacking and deformation of excision material.

Detailed description of the invention

It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described.

Fig. 2 is a kind of front view of the cutter of water dividing gap of the utility model；

Wherein, 1, cutter；11, the first arc transition；12, V-type side；13, the second arc transition；2, finished product；3, cast gate.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.

As Figure 1-Figure 2, the utility model proposes a kind of cutter 1 of water dividing gap, the V-shaped mouth in the top of cutter 1, V First arc transition 11 is set between the bottom of type mouth and the both sides of V-type mouth, and the level that distance is the mouth of a river is opened at the top of V-type mouth The straight length of projection；

It is set as the length of mouth of a river projection, it is therefore an objective to it is cut since the position of the horizontal direction most end at the mouth of a river, due to The position of most end is most thick, and when tradition cutting switches to herein since bottom, the heap of base material is superimposed with most thick herein Material, the mouth of a river that will lead to cutting form the stacking of lot of materials, and the extruding everywhere of final material influences molding effect, so first It is cut from thickness, reduces further extruding when material beneath stacks upwards to thickest part.

The second arc transition 13 is arranged in the end of the two sides of V-type mouth；

If end is straight transitions, can and the side of cutter 1 form sharp acute angle, one to carry out intensity low, be easy to cause knife The damage of tool 1, two sharp cutters 1 are inconvenient to take, and by the way that arc transition is arranged, strengthen the intensity of 1 end of cutter.

The chamfered transition of the side setting of cutter 1 diagonally downward；

Cutter 1 cut workpiece when, workpiece cutting under can be moved along chamfered transition, make cut be able to it is smooth into Row.

Groove is arranged in the lower section of chamfered transition；

When being cut into waste material, remaining waste material has the region of stacking, and the transition of groove improves the intensity of cutter 1.

Embodiment 1

Straight flange is arranged in the both sides of V-type mouth；

To the bottom squeeze of V-groove, two V-type sides 12 form shearing force, cropped to side at the mouth of a river being cut at this time Workpiece shear extrusion out, the amount of cutting are lighter than traditional cutting by gradually becoming smaller greatly.

Embodiment 2

Third circular arc is arranged in the both sides of V-type mouth, and the radius of circular arc and the radius at the mouth of a river are identical；

For the circular mouth of a river, cut using circular cutter 1, cutter 1 and the mouth of a river two circular arcs one Whole cutting is just carried out when rising, in the same time by linear cutting, material is uniformly inwardly squeezed, kept away the semi circular surface at the mouth of a river Exempt from conventional tool 1 and cut to line from point to cut to the continually changing process of cutting quantity a little again.

A variety of modifications of embodiment will be readily apparent to those skilled in the art, determine herein The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The widest scope consistent with features of novelty.
