[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This continuous extrusion molding equipment for automotive sound insulation sheets, through auxiliary components set in the inner cavity of the mixing drum, causes the spiral blades to make staggered contact with the spiked columns when driven by the motor. This causes the spiral blades to rub against the spiked columns as they push the material particles, achieving the effect of piercing and crushing larger material particles. At the same time, the cylinder slides along the inner wall of the cylinder under the combined drive of the spiral blades and spiked columns, causing magnet two to approach magnet one. The magnetic field of like poles repulsion causes the spiked columns to reset, thereby achieving continuous extrusion and impact on the material particles, improving the crushing degree of the material, and thus enabling the material entering the inner cavity of the mixing drum to be mixed evenly.
[0016] 2. This continuous extrusion molding equipment for automotive sound insulation sheets allows the arc-shaped sleeve to slide along the slide groove by rotating four threaded rods. This causes the trapezoidal block to disengage the pin from the slot, making it easy to remove the mold head body from the connecting block. After maintenance, the mold head body can be quickly installed by reversing the operation, thus facilitating the disassembly and installation of the mold head body and effectively improving the utilization rate and production efficiency of the equipment.

[0029] The auxiliary component 13 includes a cylinder 131, a magnet 132 embedded in the inner wall of the cylinder 131, a cylinder 133 and a magnet 134 respectively provided in the inner cavity of the cylinder 131, and a spike 135 fixedly assembled on the outer wall of the cylinder 133.
[0030] The connecting assembly 12 includes a threaded rod 121, the outer wall of which is threaded with an arc-shaped sleeve 123. The inner wall of the square block 11 is provided with a first groove 122 and a second groove 124. The inner cavity of the square block 11 is provided with a trapezoidal block 125, a pin 126 and a spring 127.
[0031] In the above structure, by setting the fusion cylinder 9, the spiral blade 8 is driven by the outer edge of the motor 2 to rotate. The rotating spiral blade 8 crushes the material particles in the inner cavity of the fusion cylinder 9. The spiral of the rotating spiral blade 8 makes staggered contact with the auxiliary component 13, which crushes the larger particles in the inner cavity of the fusion cylinder 9. As a result, the material particles in the inner cavity of the fusion cylinder 9 will not be granular when they are transferred to the inner cavity of the mixing cylinder 10, thereby improving the uniformity of material mixing.
[0032] In a preferred embodiment: the unattached sides of magnet 132 and magnet 134 are S poles, and the unattached sides of magnet 132 and magnet 134 are like poles and repel each other.
[0033] In the above structure, by setting magnet 132 and magnet 134, when the unmounted side of magnet 134 approaches the unmounted side of magnet 132, magnet 132 and magnet 134 will generate a magnetic field with like poles repelling each other, thereby causing magnet 134 to be buffered and reset under the magnetic field of magnet 132.
[0034] In a preferred embodiment: the outer wall of the cylinder 133 fits against the inner wall of the cylinder 131, and the diameter of the cylinder 133 is larger than the opening diameter of the cylinder 131.
[0035] In the above structure, by setting the cylinder 133, the outer wall of the cylinder 133 will slide and reset along the inner wall of the cylinder 131, so that the cylinder 131 will fix the cylinder 133, whose diameter is larger than the opening of the cylinder 131, into the inner wall of the cylinder 131.
[0036] In a preferred embodiment: the auxiliary component 13 is regarded as a movable component, and all movable components are arranged in parallel in the inner wall of the fusion cylinder 9, and the outer wall of the spike column 135 is staggered with the spiral of the spiral blade 8.
[0037] In the above structure, by setting the auxiliary component 13, when the spiral blade 8 rotates, the rotating blade will come into contact with the auxiliary component 13 set on the inner wall of the fusion cylinder 9. In this way, the auxiliary component 13 will assist the spiral blade 8, so that when the spiral blade 8 intersects with the auxiliary component 13, it will pierce and crush larger particles, thereby effectively improving the uniformity of material mixing.
[0038] In a preferred embodiment: the outer wall of the square block 11 has the same shape as the inner wall of the square groove 6, and the outer wall of the square block 11 is adapted to the inner wall of the square groove 6.
[0039] In the above structure, by setting the square block 11 and the square groove 6, when the connecting block 5 and the mold head body 14 are separated for maintenance, the mold head body 14 will slide along the inner wall of the square groove 6 through the connecting component 12, thereby realizing the separation of the connecting block 5 and the mold head body 14, so as to facilitate the subsequent maintenance and cleaning of the mold head body 14.
[0040] In a preferred embodiment: the outer wall of the arc sleeve 123 has the same shape as the inner wall of the first slide groove 122, and the outer wall of the arc sleeve 123 is slidably fitted to the inner wall of the first slide groove 122; there are two trapezoidal blocks 125, and the tops of the two trapezoidal blocks 125 are slidably fitted to the bottom of the arc sleeve 123; the bottoms of the two trapezoidal blocks 125 have the same shape as the inner wall of the second slide groove 124, and the bottoms of the trapezoidal blocks 125 are slidably fitted to the inner wall of the second slide groove 124; the spring 127 is located on the outer wall of the pin 126, and one end of the spring 127 overlaps with the trapezoidal block 125 and the other end overlaps with the inner wall of the square block 11; the outer wall of the pin 126 has the same shape as the inner wall of the slot 7, and the outer wall of the pin 126 is adapted to the inner wall of the slot 7.
[0041] In the above structure, by setting up the threaded rod 121, the arc-shaped sleeve 123, the trapezoidal block 125, the pin 126, and the spring 127, by rotating the threaded rod 121, the outer wall of the threaded rod 121 will drive the arc-shaped sleeve 123 to slide along the direction of the first slide groove 122. The bottom of the sliding arc-shaped sleeve 123 will slide against the outer wall of the two trapezoidal blocks 125. After the arc-shaped sleeve 123 disengages from the two trapezoidal blocks 125, the two trapezoidal blocks 125 will slide relative to each other along the direction of the second slide groove 124 under the spring compression of the spring 127. The sliding two trapezoidal blocks 125 will drive the pin 126 to disengage from the inner wall of the slot 7, thereby realizing the disassembly and removal of the mold head body 14 and the connecting block 5. At the same time, by performing the opposite operation, the mold head body 14 and the connecting block 5 can be conveniently installed.
[0042] In a preferred embodiment: the connecting component 12 is regarded as a movable component, and the number of the movable components is four, corresponding to the square slots 6;
[0043] In the above structure, by setting the connecting components 12, when the mold head body 14 is separated from the square groove 6 by the square block 11, the four connecting components 12 are operated to separate the four connecting components 12 from their corresponding square grooves 6, thereby realizing the convenient disassembly of the mold head body 14.
[0044] Working Principle: When in use, the motor 2 is started, and its output shaft drives the spiral blade 8 to rotate. The rotating spiral blade 8 continuously extrudes material particles from the feed inlet 4 to the other end of the extrusion cylinder 3. Simultaneously, as the material particles pass through the inner cavity of the mixing cylinder 9, the spiral blade 8 pushes them to collide with the spiked column 135. The spiked column 135 pierces and crushes larger particles. Simultaneously, as the spiral blade 8 extrudes the spiked column 135, the cylinder 133 slides along the inner wall of the cylinder 131, causing magnet 134 to move closer to magnet 132. This creates a repulsive magnetic field between the unattached S poles of magnet 132 and magnet 134, causing magnet 134 to reset under the reverse force of the magnetic field. This, in turn, pushes the spiked column 135 back to its original position. Thus, the spiked column 135 continuously impacts and extrudes the material particles. The processed material then enters the mixing cylinder 10. Inside, since the material particles have been fully crushed, they can be mixed more evenly in the mixing drum 10. The fused material in the inner cavity of the mixing drum 10 will be transferred to the die head body 14 through the connecting block 5 and the square groove 6 for continuous extrusion molding, thereby effectively improving the sheet extrusion molding efficiency of the equipment.
[0045] Simultaneously, by rotating the four threaded rods 121, the threaded rods 121 drive the arc-shaped sleeve 123 to slide along the direction of the first slide groove 122. The bottom of the sliding arc-shaped sleeve 123 will slide against the outer wall of the two trapezoidal blocks 125. After the arc-shaped sleeve 123 disengages from the two trapezoidal blocks 125, the two trapezoidal blocks 125 slide relative to each other along the direction of the second slide groove 124 under the spring compression of the spring 127. The sliding two trapezoidal blocks 125 will drive the pin 126 to disengage from the inner wall of the slot 7. At this time, the mold head body 14 can be removed by sliding the square block 11 along the inner wall of the square groove 6, thereby achieving disengagement from the connecting block 5, thus realizing convenient disassembly and removal of the mold head body 14.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
