Abstract
The utility model relates to an extrusion cutting machine die plate anti-cracking structure, the die plate comprises a feeding section and an extrusion section, the feeding section is provided with a horn mouth flow passage, the extrusion section is provided with a molding flow passage, and the horn mouth flow passage is communicated with the molding flow passage; the method is characterized in that: the extrusion section is provided with a flat plate on two parallel long edges of the outlet end respectively, and two ends of the two flat plates are fastened through bolts. The utility model has the advantages that the extrusion section of the mouth-shaped plate passes through the end part of the outlet of the extrusion equipment and is directly reinforced by the clamping plate, thereby greatly improving the deformation-preventing capacity and the cracking-preventing grade; moreover, the reinforcing, dismounting and mounting are very convenient, the runner structure of the mouth-shaped plate is not influenced, the rapid reinforcing of the existing mouth-shaped plate is realized, and the reinforcing method is simple and feasible.
Description
The technical field is as follows:
the utility model belongs to rubber is extruded and is equipped the field, in particular to extrusion cutting machine die plate anti-cracking structure especially adopts the structure of anchor clamps lock solid extruding the section.
Background art:
because of the problems of cost and the like, most of the molding processes used by the prior domestic giant radial engineering tire use semi-finished products of each part produced by a tire side extruder, and then are laminated and molded on a molding drum, because the sizes of all the parts are different, the extrusion sizes of the port plate flow passages are also different, the sizes of the extrusion ports of the prior cold feeding rubber extruders are fixed, and when a large block of molding compound is produced, the port plate is easy to crack, deform and the like due to the higher extrusion pressure, so that the produced molding compound has the problems of rough edges, excessive edges and the like. The problems of over-thickness of the molded rubber edge part, burrs and the like directly affect the molding quality of the tire, so that the mouth-shaped plate needs to be improved.
To this end, the skilled person also thinks of many ways to reinforce the plate, one being the solution of adding fixing pegs between the upper plate and the lower plate, such as: patent application No. 201620581822.8, discloses a die device suitable for both left and right sidewall extrusion; and the other type is reinforced by an external die box, such as a general die plate assembly for tread extrusion disclosed in patent application No. 201611228639.0; or an inner and an outer mouth-shaped plates are added in the mouth-shaped box, such as patent application No. 202010208370.X, which discloses a mouth-shaped extruding device suitable for tread three-compound extrusion with a conductive structure.
However, these technical solutions do not substantially improve the strength of the plate itself, and how to improve the strength of the plate becomes the object of the present invention.
The invention content is as follows:
the utility model aims at designing a direct extrusion cutting machine die plate anti-cracking structure who sets up anchor clamps and consolidate on the outlet end of extruding the section.
The utility model discloses technical scheme realizes like this: a mouth-shaped plate anti-cracking structure of an extrusion cutting machine comprises a feeding section and an extrusion section, wherein the feeding section is provided with a bell mouth flow passage, the extrusion section is provided with a molding flow passage, and the bell mouth flow passage is communicated with the molding flow passage; the method is characterized in that: the extrusion section is provided with a flat plate on two parallel long edges of the outlet end respectively, and two ends of the two flat plates are fastened through bolts.
The cross section of the feeding section is larger than that of the extruding section, and a step capable of abutting against the edge of the equipment opening is formed at the joint.
The utility model has the advantages that the extrusion section of the mouth-shaped plate passes through the end part of the outlet of the extrusion equipment and is directly reinforced by the clamping plate, thereby greatly improving the deformation-preventing capacity and the cracking-preventing grade; moreover, the reinforcing, dismounting and mounting are very convenient, the runner structure of the mouth-shaped plate is not influenced, the rapid reinforcing of the existing mouth-shaped plate is realized, and the reinforcing method is simple and feasible.
Description of the drawings:
the present invention will be further explained with reference to the following specific drawings:
FIG. 1 is a schematic view of anti-cracking structure of a die plate of an extrusion cutting machine
FIG. 2 is a schematic cross-sectional view of an anti-cracking structure of a die plate of an extrusion cutting machine
FIG. 3 is a schematic view showing the structural decomposition of the die plate of the extrusion cutting machine for preventing cracking
Wherein
1-feeding section 11-bell mouth flow channel
2-extrusion section 21-forming flow channel
3-step 4-splint 5-bolt
The specific implementation mode is as follows:
referring to fig. 1, fig. 2 and fig. 3, extrusion cutting machine die plate structure of preventing ftractureing, die plate include feed section 1 and extrude section 2, and feed section 1 cross-section is greater than and extrudes section 2 cross-sections, and the handing-over department forms a step 3, extrudes section 2 and passes the extrusion equipment export to can contradict at the mouth edge of extrusion equipment with the help of step 3, form and extrude atress and location die plate, and extrude 2 exit ends of section and can expose the extrusion equipment, facilitate for the reinforcement.
The feeding section 1 of the mouth-shaped plate is provided with a bell mouth runner 11, the extrusion section 2 is provided with a molding runner 21, and the bell mouth runner 11 is communicated with the molding runner 21 so as to extrude and mold the sent rubber material; wherein: the extrusion section 2 is provided with a flat plate 4 on two parallel long edges of the outlet end respectively, and two ends of the two flat plates are fastened through bolts 5. In the figure, a threaded hole matched with a bolt is processed in one clamping plate, and after the bolt 5 passes through one clamping plate, the end part is directly locked in the threaded hole of the other clamping plate. Two identical clamping plates can also be adopted, and the bolt 5 sequentially penetrates through a nut on the rear end parts of the two clamping plates for fastening.
During operation, the mouth-shaped plate is firstly arranged at the outlet of the extrusion equipment, and then the clamping plate 4 is arranged at the outlet end of the extrusion section 2 exposed out of the outlet of the equipment; the mouth plate can be dismounted by reverse operation.
