Description
Technical Field
The utility model belongs to the technical field of injection moulding equipment, concretely relates to extruder discharge gate leak protection component.
Background
At present, the plastic extruder mainly extrudes and molds materials through the matching of a discharge port and a mold, and when a discharge nozzle of the existing extrusion equipment is butted with an injection port of the molding mold, the existing extrusion equipment is only fixed by the gravity of a machine body, the sealing performance is poor, so that plastic materials can be leaked from a gap when extruded, the plastic materials are easy to leak, the plastic materials are wasted, the outer wall of the mold is polluted, and the cleaning is difficult.
Disclosure of Invention
In order to overcome the problems that when a discharge nozzle of extrusion equipment in the background technology is butted with a glue injection port of a forming die, the discharge nozzle is only pressed and fixed by the gravity of a machine body, the sealing performance is poor, so that when plastic is extruded, glue materials can leak from gaps, the leakage is easy to generate, the plastic is wasted, the outer wall of the die is polluted, and the cleaning is difficult, the utility model provides a leakage-proof component for a discharge port of an extruder; the discharge nozzle of the extrusion equipment is connected with the glue injection port of the forming die through threads, so that the sealing performance is better, the glue is effectively prevented from leaking from a gap when the plastic is extruded, the outer wall of the die cannot be polluted, and the cleaning difficulty and frequency are reduced; avoid the material waste, practice thrift the cost.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the anti-leakage component for the discharge port of the extruder mainly comprises an extrusion gun, a butt joint and a die, wherein the tail end of the extrusion gun is provided with the discharge port, the die is provided with a glue injection hole with internal threads, and two ends of the butt joint are respectively connected with the discharge port and the glue injection hole through left-handed threads and right-handed threads; the thread pitches of the left-handed thread and the right-handed thread are the same; the butt joint is provided with a hexagonal section which is convenient to bear force during disassembly.
The utility model has the advantages that:
the discharge nozzle of the extrusion equipment is connected with the glue injection port of the forming die through the threads, so that the sealing performance is better, the glue material is effectively prevented from leaking from the gap when the plastic is extruded, the outer wall of the die is not polluted, and the cleaning difficulty and frequency are reduced; avoid the material waste, practice thrift the cost.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
The utility model discloses an extruder discharge port leakage-proof component, which mainly comprises an extrusion gun 1, a butt joint 2 and a mould 3, wherein the tail end of the extrusion gun 1 is provided with a discharge port 11, the mould 3 is provided with a glue injection hole 31 with internal threads, and two ends of the butt joint 2 are respectively connected with the discharge port 11 and the glue injection hole 31 through left-handed threads and right-handed threads; the two ends of the butt joint 2 are respectively connected through the left-hand thread and the right-hand thread, when butt joint before glue injection or disassembly after glue injection is carried out, butt joint or disassembly of the butt joint 2, the discharge hole 11 and the glue injection hole 31 can be realized only by rotating the butt joint 2, the extrusion gun 1 or the die 3 does not need to be rotated, the operation is simple, and the sealing effect is good; the thread pitches of the left-handed thread and the right-handed thread are the same, so that the meshing amount of the butt threads at the two ends is the same during installation or disassembly; the butt joint 2 is provided with a hexagonal section 21 which is convenient to bear force during disassembly. The discharge nozzle of the extrusion equipment is connected with the glue injection port of the forming die through the threads, so that the sealing performance is better, the glue material is effectively prevented from leaking from the gap when the plastic is extruded, the outer wall of the die is not polluted, and the cleaning difficulty and frequency are reduced; avoid the material waste, practice thrift the cost.
The working process is as follows:
butt joint work: the extrusion gun 1, the butt joint 2 and the die 3 are aligned in sequence, the butt joint 2 is rotated, and the left-handed thread and the right-handed thread at the two ends of the butt joint 2 are respectively and synchronously connected with the discharge hole 11 and the glue injection hole 31. Starting injection molding after the threads are pre-tightened; disassembling: and the left-handed thread and the right-handed thread at the two ends of the butt joint 2 and the butt joint 2 are synchronously withdrawn from the discharge hole 11 and the glue injection hole 31 respectively until the disassembly is finished.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
