[0048] S2, the mounting shell 111 moves downward, the mounting column 122 is embedded in the raw material, and the mounting frame 121 is separated from the mounting shell 111 and fixed on the frame 2;

[0049] S3, the mounting shell 111 continues to move downward, the outer extrusion block 11 moves closer to the mounting column 122, the first pressing block 124 and the second pressing block 125 extend to the outside of the mounting column 122 and form an extrusion ring 12, the space between the outer extrusion block 11 and the extrusion ring 12 is reduced and the raw material is pushed to extend upward to fill the molding mechanism 1, forming a rubber plug blank with a longer insertion portion;

[0050] S4, the mounting shell 111 moves upward to separate the forming mechanism 1 from the blank;

[0051] S5, the blank is cooled and shaped, and then the blank is cut from the sheet material.

[0052] Specifically, during the processing, the outer extrusion block 11 moves closer to the mounting column 122, the first pressing block 124 and the second pressing block 125 extend to the outside of the mounting column 122 and form an extrusion ring 12, and the space between the outer extrusion block 11 and the extrusion ring 12 is reduced to gather the raw materials, and the outer extrusion block 11 and the extrusion ring 12 cooperate to push the raw materials upward to fill the molding mechanism 1, forming a rubber plug blank with a longer insertion portion.

[0053] Embodiment 2

[0054] like Figure 1-16 As shown, a halogenated butyl rubber plug production system is used to implement the halogenated butyl rubber plug processing technology of the above-mentioned embodiment 1, including a frame 2, on which the following are arranged:

[0055] The forming mechanism 1 comprises a mounting shell 111 movably mounted on the frame 2, mounting columns 122 distributed in a rectangular array are movably arranged on the mounting shell 111, and a plurality of external extrusion blocks 11 corresponding to and surrounding the mounting columns 122 are movably arranged on the mounting shell 111;

[0056] The heating plate 21 is opposite to the forming mechanism 1 and is used to heat the raw material, wherein:

[0057] The mounting column 122 moves with the mounting shell 111 to embed the raw material and separate from the mounting shell 111 , and the mounting shell 111 continues to move to move the outer extrusion block 11 downward and close together, so that the raw material fills the cavity between the outer extrusion block 11 and the mounting column 122 .

[0058] Specifically, the frame 2 is provided with a guide rod 22 for guiding the movement of the mounting shell 111, and conveyor belts 23 for transporting sheet materials are provided on both sides of the frame 2. The mounting shell 111, the outer extrusion block 11, the mounting column 122 and the extrusion ring 12 are combined to form an upper mold for extruding the sheet material.

[0059] Furthermore, when carrying out production work, the sheet raw material is first preheated and placed on the heating plate 21 of the frame 2. The heating plate 21 continuously keeps the raw material warm so that the raw material maintains a certain fluidity. Then the mounting shell 111 moves downward along the guide rod 22 on the frame 2, the mounting column 122 is embedded in the raw material, and the mounting frame 121 is separated from the mounting shell 111 and fixed on the frame 2. The mounting shell 111 continues to move downward, and the outer extrusion block 11 moves closer to the mounting column 122. The space between the outer extrusion block 11 and the extrusion ring 12 is reduced and pushes the raw material to extend upward to fill the molding mechanism 1 to form a rubber plug blank with a longer insertion portion. Then the mounting shell 111 moves upward to separate the molding mechanism 1 from the blank, and the blank leaves the heating plate 21 and gradually cools and takes shape. Then the blank is cut from the sheet raw material to obtain a rubber plug with a longer insertion portion.

[0060] In the above technical scheme, when carrying out production work, the sheet raw material is first preheated and placed on the heating plate 21 of the frame 2. The heating plate 21 continuously keeps the raw material warm so that the raw material maintains a certain fluidity. Then the mounting shell 111 moves downward along the guide rod 22 on the frame 2, the mounting column 122 is embedded in the raw material, and the mounting frame 121 is separated from the mounting shell 111 and fixed on the frame 2. The mounting shell 111 continues to move downward, and the outer extrusion block 11 moves closer to the mounting column 122. The space between the outer extrusion block 11 and the extrusion ring 12 is reduced and pushes the raw material to extend upward to fill the molding mechanism 1 to form a rubber plug blank with a longer insertion portion. Then the mounting shell 111 moves upward to separate the molding mechanism 1 from the blank, and the blank leaves the heating plate 21 and gradually cools and shapes. Then the blank is cut from the sheet raw material to obtain a rubber plug with a longer insertion portion.

[0061] As a further embodiment of the present invention, a plurality of first pressing blocks 124 and a plurality of second pressing blocks 125 are movably disposed on the mounting column 122 , and the first pressing blocks 124 and the second pressing blocks 125 move to combine to form an extrusion ring 12 extending outside the mounting column 122 .

[0062] Specifically, a mounting plate 123 is disposed on the mounting column 122 , and a plurality of first pressing blocks 124 and a plurality of second pressing blocks 125 are slidably mounted on the mounting plate 123 .

[0063] Furthermore, after the bottom of the mounting column 122 is embedded in the sheet material, a pair of external extrusion blocks 11 corresponding to the mounting column 122 move closer to the mounting column 122, and the bottom of the external extrusion block 11 pushes the material closer to the mounting column 122. At this time, multiple first pressing blocks 124 and multiple second pressing blocks 125 move toward the outside of the mounting column 122 to form an extrusion ring 12 extending to the outside of the mounting column 122, further reducing the cavity between the mounting column 122 and the external extrusion block 11, and then pushing the material inside the cavity to extend upward, so as to form a rubber plug blank with a longer insertion portion.

[0064] As another embodiment further provided by the present invention, a mounting frame 121 for supporting a plurality of mounting posts 122 is slidably disposed inside the mounting shell 111 , and a locking rod 127 for locking the mounting frame 121 on the rack 2 is movably disposed.

[0065] Specifically, a slope is provided on the top of the locking rod 127 , a spring is provided between the locking rod 127 and the mounting frame 121 , a friction block 128 made of rubber material for squeezing the mounting frame 121 is provided on the mounting shell 111 , and a locking hole adapted to the locking rod 127 is opened on the guide rod 22 .

[0066] Furthermore, in the process of the mounting shell 111 moving downward, the mounting frame 121 is fixed to the mounting shell 111 by the friction block 128, and the mounting column 122 on the mounting frame 121 moves downward and gradually embeds into the sheet material on the heating plate 21. When the mounting column 122 reaches the predetermined position, the locking rod 127 faces the locking hole on the guide rod 22. The locking rod 127 is inserted into the locking hole under the push of the spring, and the mounting frame 121 and the mounting column 122 are fixed to the frame 2. At this time, the mounting shell 111 can continue to move downward relative to the mounting frame 121.

[0067] As another embodiment further provided by the present invention, a driving disk 13 for driving the first pressing block 124 and the second pressing block 125 to move is rotatably disposed inside the mounting column 122, and the mounting frame 121 moves relative to the mounting shell 111 to rotate the driving disk 13.

[0068] Specifically, a gear ring 135 is provided on the driving disk 13, a rack 136 meshing with the gear ring 135 is provided inside the mounting frame 121, a spring is provided between the rack 136 and the mounting frame 121, a traction rope 137 is provided between the rack 136 and the mounting shell 111, and a cylindrical tenon rod 126 is provided on the first pressure block 124 and the second pressure block 125. A first guide groove 131 adapted to the tenon rod 126 and used to drive the first pressure block 124 to move and a second guide groove 132 used to drive the second pressure block 125 are respectively provided on the driving disk 13, and the second guide groove 132 includes an arc portion 133 and an annular portion 134, and the annular portion 134 is coaxial with the driving disk 13.

[0069] Furthermore, in the process of the installation shell 111 moving downward relative to the installation frame 121, the traction rope 137 between the installation shell 111 and the rack 136 is tightened, the traction rope 137 drives the rack 136 to move, the rack 136 drives the driving plate 13 to rotate through the gear ring 135 meshing therewith, the arc portion 133 of the second guide groove 132 on the driving plate 13 pushes the tenon rod 126 on the second pressing block 125 to move, and then pushes the second pressing block 125 to move in the direction away from the axis of the installation column 122, and at the same time, the first guide groove 131 pushes the second pressing block 125 to move. The tenon rod 126 on a pressure block 124 moves, driving the first pressure block 124 to move in a direction away from the axis of the mounting column 122. When the second pressure block 125 reaches the predetermined position, the tenon rod 126 on the second pressure block 125 enters the annular portion 134 of the second guide groove 132 and moves along the annular portion 134. The second pressure block 125 no longer moves. At this time, the first guide groove 131 continues to push the first pressure block 124 to move, so that the first pressure block 124 is embedded between two adjacent second pressure blocks 125 to seal the gap between the second pressure blocks 125.

[0070] As another embodiment further provided by the present invention, a second cable 119 is provided between the outer extrusion block 11 and the corresponding mounting column 122 , and the mounting shell 111 moves relative to the mounting frame 121 to move the outer extrusion block 11 downward and closer to the corresponding mounting column 122 .

[0071] Specifically, the outer extrusion block 11 is provided with a tenon block 118 extending into the interior of the mounting shell 111, the mounting shell 111 is provided with a tenon groove for guiding the movement of the tenon block 118, a spring is provided between the tenon block 118 and the mounting shell 111, and a second cable 119 is provided between the tenon block 118 and the mounting column 122, and the second cable 119 has a certain elasticity.

[0072] Furthermore, when the mounting shell 111 moves downward relative to the mounting frame 121, the distance between the tenon block 118 on the mounting shell 111 and the mounting column 122 on the mounting frame 121 increases, thereby tightening the second cable 119 therebetween. The second cable 119 pulls the tenon block 118 and the outer extrusion block 11 toward the mounting column 122 until the pair of outer extrusion blocks 11 are brought together.

[0073] As another embodiment further provided by the present invention, a horizontal portion 112 and an inclined portion 113 are provided on the outer extrusion block 11, and a pair of outer extrusion blocks 11 are brought together so that the two inclined portions 113 are combined to form a truncated cone shell structure.

[0074] Specifically, in the process of the mounting shell 111 moving downward relative to the mounting frame 121, a pair of outer extrusion blocks 11 gradually move together, so that the outer extrusion block 11 contacts the mounting column 122, and the space between the mounting column 122 and the outer extrusion block 11 is closed. The mounting shell 111 continues to move downward, and the second cable 119 is stretched. At this time, the truncated cone-shaped inclined portion 113 extrude the sheet material, so that the sheet material moves upward along the inner wall of the inclined portion 113, so that the material further fills the cavity between the outer extrusion block 11 and the mounting column 122.

[0075] As another embodiment further provided by the present invention, a plurality of movable pieces 114 are hinged at the bottom of the inclined portion 113 , and the movable pieces 114 move downward with the outer extrusion block 11 to embed the raw material and push the raw material to move toward the mounting column 122 .

[0076] Specifically, in the process of the mounting shell 111 moving downward, the movable sheet 114 on the outer extrusion block 11 will first be inserted into the sheet material, and then the mounting shell 111 moves downward relative to the mounting frame 121, and the outer extrusion block 11 moves closer to the mounting column 122. At this time, the movable sheet 114 can push part of the raw material closer to the mounting column 122, so that more raw materials are located under the outer extrusion block 11, which makes it convenient for the outer extrusion block 11 to press the raw materials into the chamber between the outer extrusion block 11 and the mounting column 122.

[0077] As another embodiment further provided by the present invention, a top block 115 for fixing the movable sheet 114 is movably provided inside the outer extrusion block 11, and a pair of outer extrusion blocks 11 are brought together to separate the top block 115 from the fixed sheet.

[0078] Specifically, when the pair of external extrusion blocks 11 are not close together, the top block 115 fixes the movable sheet 114, so that when the external extrusion block 11 approaches the mounting column 122, the movable sheet 114 can push part of the raw material toward the mounting column 122. When the pair of external extrusion blocks 11 approaches each other, the top block 115 is separated from the movable sheet 114, and the movable sheet 114 can rotate freely, so that during the process of the external extrusion block 11 extruding the raw material, excess raw material can flow out from under the external extrusion block 11, and the movable sheet 114 rotates relative to the external extrusion block 11 to prevent the movable sheet 114 from being inserted too deeply and damaging the heating plate 21 on the frame 2.

[0079] As another embodiment further provided by the present invention, the middle portion of the movable sheet 114 is rotatably mounted on the inclined portion 113 , and a trigger block 116 for driving the top block 115 to move is movably provided on the outer extrusion block 11 .

[0080] Specifically, a spring is provided between the top block 115 and the outer extrusion block 11 , a spring is provided between the trigger block 116 and the outer extrusion block 11 , a slope is provided at the top of the top block 115 , and a first cable 117 is provided between the top block 115 and the trigger block 116 .

[0081] Furthermore, when carrying out production work, the sheet raw material is first preheated and placed on the heating plate 21 of the frame 2. The heating plate 21 continuously keeps the raw material warm so that the raw material maintains a certain fluidity. Then the mounting shell 111 moves downward along the guide rod 22 on the frame 2. The mounting frame 121 is fixed to the mounting shell 111 by the friction block 128. The mounting column 122 on the mounting frame 121 moves downward and gradually embeds into the sheet raw material on the heating plate 21. When the mounting column 122 reaches the predetermined position, the locking rod 127 faces the locking hole on the guide rod 22. The locking rod 127 is inserted into the locking hole under the push of the spring, and the mounting frame 121 and the mounting column 122 are fixed to the frame 2. At this time, the mounting shell 111 can continue to move downward relative to the mounting frame 121.

[0082] The mounting shell 111 continues to move downward relative to the mounting frame 121, and the friction plate gradually separates from the mounting frame 121. The movable sheet 114 on the outer extrusion block 11 will be first inserted into the sheet material, and the distance between the tenon block 118 on the mounting shell 111 and the mounting column 122 on the mounting frame 121 increases, so that the second cable 119 between the two is tightened, and the second cable 119 pulls the tenon block 118 and the outer extrusion block 11 closer to the mounting column 122. At this time, the movable sheet 114 can push part of the raw material closer to the mounting column 122, so that more raw material is located under the outer extrusion block 11, which is convenient for the outer extrusion block 11 to press the raw material into the outer extrusion block The outer extrusion block 11 continues to move until the pair of outer extrusion blocks 11 are close together, and the pair of outer extrusion blocks 11 push the trigger block 116 against each other, and the trigger block 116 pulls the first cable 117 to move, and the first cable 117 drives the top block 115 to move, so that the top block 115 is separated from the movable sheet 114, and the movable sheet 114 can rotate freely, so that in the process of the outer extrusion block 11 extruding the raw material, the excess raw material can flow out from the bottom of the outer extrusion block 11, and the movable sheet 114 rotates relative to the outer extrusion block 11 to avoid the movable sheet 114 being inserted too deep and damaging the heating plate 21 on the frame 2.

[0083] The mounting shell 111 continues to move downward, and the second cable 119 is stretched. At this time, the truncated cone shell-shaped inclined portion 113 squeezes the sheet material, so that the sheet material moves upward along the inner wall of the inclined portion 113, so that the material further fills the chamber between the outer extrusion block 11 and the mounting column 122. At the same time, the traction rope 137 between the mounting shell 111 and the rack 136 is tightened, and the traction rope 137 drives the rack 136 to move. The rack 136 drives the driving disk 13 to rotate through the gear ring 135 meshing therewith, and the arc portion 133 of the second guide groove 132 on the driving disk 13 pushes the tenon rod 126 on the second pressing block 125 to move, thereby pushing the second pressing block 125 to move in the direction away from the axis of the mounting column 122. At the same time, the first guide groove 131 pushes the tenon rod 126 on the first pressing block 124 to move, driving the first pressing block 1 24 moves in the direction away from the axis of the mounting column 122. When the second pressing block 125 arrives at the predetermined position, the tenon rod 126 on the second pressing block 125 enters the annular portion 134 of the second guide groove 132 and moves along the annular portion 134. The second pressing block 125 no longer moves. At this time, the first guide groove 131 continues to push the first pressing block 124 to move, so that the first pressing block 124 is embedded between two adjacent second pressing blocks 125 to seal the gap between the second pressing blocks 125. The first pressing block 124 and the second pressing block 125 are combined to form an extrusion ring 12, which extends to the outside of the mounting column 122, further reducing the cavity between the mounting column 122 and the outer extrusion block 11, and then pushing the raw material inside the cavity to extend upward, so as to form a rubber plug blank with a longer insertion portion, and at the same time can reduce the amount of material used in the production of the rubber plug.

[0084] At this time, the heating plate 21 stops working, the raw material gradually cools and solidifies to form a rubber plug blank, then the mounting shell 111 moves upward, the outer extrusion block 11 moves upward with the mounting shell 111, the second cable 119 gradually relaxes, the outer extrusion block 11 gradually resets, and the top block 115 gradually abuts against the movable sheet 114 under the push of the spring, fixing the movable sheet 114 on the outer extrusion block 11, and at the same time, the friction block 128 gradually contacts the mounting frame 121, the traction rope 137 relaxes, and the rack 136 drives the driving disk 13 to rotate in the opposite direction, so that the first pressing block 124 and the second pressing block 124 are The second pressure block 125 retracts into the mounting column 122, and the mounting frame 121 is gradually embedded in the gap between the friction block 128 and the mounting frame 121, and the slope of the top of the locking rod 127 on the mounting frame 121 abuts against the top of the locking hole, so that the locking rod 127 gradually retracts into the mounting frame 121, and the mounting frame 121 is fixed in the mounting shell 111. The mounting shell 111 continues to move upward with the mounting frame 121, and the mounting column 122 is separated from the blank. Then, the blank is cut from the sheet material and polished to obtain a rubber plug with a longer insertion portion.

[0085] Furthermore, in the above embodiment, cooling water channels can be set inside the outer extrusion block 11 and the inner extrusion ring 12 to accelerate the cooling and solidification of the blank; the friction block 128 in the above embodiment can be provided with downward slanting serrations on its contact surface with the mounting frame 121 to facilitate the downward movement of the mounting frame 121 relative to the mounting shell 111 and hinder the upward movement of the mounting frame 121 relative to the mounting shell 111.

[0086] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
