Description

Technical Field

[0001] The present invention relates to the technical field of silicone rubber processing, and particularly relates to a silicone rubber molding device. Background Art

[0002] Silicone rubber has excellent characteristics such as high and low temperature resistance, oxidation resistance, and electrical insulation, and is widely used in the fields of electronics, medical treatment, and automobiles. Its unique high elasticity and low compression set make silicone rubber perform excellently in seals and gaskets, etc.

[0003] In order to make silicone rubber form a specific shape, usually the blank is placed in a molding die, and hot pressing is carried out through the molding die. After molding, the molded silicone rubber is taken off from the molding die by manual or automatic equipment. After the silicone rubber is taken off from the molding die, there will be excess waste in the molding die. The waste and the molded silicone rubber need to be peeled off by manual or special equipment, which is time-consuming and laborious. Moreover, waste is likely to remain in the cavity of the molding die. If not cleaned in time, it will cause the quality of the silicone rubber molded next time to decrease. Summary of the Invention

[0022] As Figure 5 shown in the figure, the air flow switching mechanism further includes an elastic limiting block 301. A vertical groove is opened on the inner wall of the air flow pipe 201. The elastic limiting block 301 is vertically slidably connected in the vertical groove.

The elastic limiting block 301 is used in cooperation with the rotating plate 204, and the elastic limiting block 301 is used to limit the rotating plate 204.

[0023] As Figure 3 shown in Figure 4 the figure, the air flow switching mechanism further includes a plugging plate B 401. The rear end of the sliding rod 206 is hinged to the plugging plate B 401 through a support rod. The plugging plate B 401 is slidably connected to the inner wall of the air flow pipe 201. An L-shaped pipe 402 is jointly communicated between the air flow pipe 201 and the guide air pipe 203. The plugging plate B 401 is used to block the communication part between the air flow pipe 201 and the L-shaped pipe 402.

[0024] As Figure 3 and Figure 6 shown in Figure 7 the figure, it further includes a separation mechanism. The separation mechanism includes a vertical pipe A 501. The bottom end of the guide air pipe 203 is communicated with a plurality of uniformly distributed vertical pipes A 501.

A ventilation hole A is opened on the outer wall of the vertical pipe A 501 in a penetrating manner. A ventilation hole B is opened on the outer wall of the sleeve 503 in a penetrating manner. When the ventilation hole A of the vertical pipe A 501 is communicated with the ventilation hole B of the sleeve 503, external air can enter the vertical pipe A 501.

[0025] AsFigure 6 As shown, the separating mechanism further includes a one-way damping piece 601. The one-way damping piece 601 is fixedly embedded on the outer wall of the vertical pipe B502. The one-way damping piece 601 is used in cooperation with the sleeve 503 and is used to limit the moving speed of the sleeve 503.

[0026] As Figure 7 As shown, the separating mechanism further includes a round cover 701. The round cover 701 is fixedly sleeved on the outer wall of the sleeve 503. A notch is penetratively formed on the outer wall of the round cover 701. The notch of the round cover 701 and the vent hole B of the sleeve 503 are on the same horizontal plane. An impeller A702 is slidably connected to the bottom end of the round cover 701. The impeller A702 is rotatably sleeved on the outer wall of the sleeve 503. Vertical rods are symmetrically fixedly connected to the bottom of the impeller A702. The bottom ends of the vertical rods are rotatably connected to a cutting knife 703. When the cutting knife 703 moves, it can separate the formed silicone rubber from the waste.

[0027] As Figure 8 And Figure 9 As shown, it further includes a cleaning mechanism. The cleaning mechanism includes an electric guide rail 801. The electric guide rail 801 is fixedly connected to the base 1. A sliding frame 802 is horizontally slidably connected in the electric guide rail 801. A cylinder A803 is installed at the bottom of the sliding frame 802. A mounting frame 804 is penetratively slidably connected to the sliding frame 802. The air flow pipe 201 and the mounting box 202 are both fixedly connected to the mounting frame 804. A cylinder B901 is installed at the bottom of the mounting frame 804. The telescopic end of the cylinder B901 is fixedly connected to three uniformly distributed vertical pipes C902 through a support plate. The inner walls of the three vertical pipes C902 are movably connected to sliding pipes 903. The bottom end of the sliding pipe 903 is penetratively and vertically slidably connected to a frustum 904 and is symmetrically horizontally slidably connected to a sliding rod 905. A compression spring C is arranged between the sliding rod 905 and the sliding pipe 903. A collection box 906 is detachably installed on the outer wall of the sliding rod 905. A peeling knife 907 is fixedly connected to one side of the collection box 906.

[0028] Initially, the installation box 202 is located above the rear of the molding die 101. The rotating plate 204 is in a vertical state. The blocking plate B401 blocks the connection between the L-shaped pipe 402 and the air flow pipe 201. The front inclined surface of the elastic limiting block 301 contacts the rear outer wall of the rotating plate 204. The compression spring B is in a released state. There is a gap between the inner bottom of the vertical pipe A501 and the inner wall of the sleeve 503. The ventilation hole A of the vertical pipe A501 is misaligned with the ventilation hole B of the sleeve 503. First, the silicone rubber blank is placed into the molding die 101, and the silicone rubber blank in the molding die 101 is hot-pressed by hot pressing in the prior art to form the silicone rubber. Then, the hot pressing equipment is separated from the molding die 101. Since the silicone rubber is formed by hot pressing, the temperature of the silicone rubber is relatively high at this time, and the elastic deformation generated by the silicone rubber when subjected to an external force is relatively large. It is necessary to cool down the silicone rubber. First, the electric guide rail 801 is used to control the sliding frame 802 to slide forward. The sliding frame 802 drives the mounting frame 804 to move forward through the cylinder A803. The mounting frame 804 drives the air flow pipe 201 and the installation box 202 to move forward. The installation box 202 drives a plurality of vertical pipes A501 to move forward through the air guide pipe 203. The vertical pipe A501 drives the corresponding vertical pipe B502 and the sleeve 503 to move forward until the centers of the plurality of vertical pipes A501 are respectively aligned with the center of the molding cavity of the molding die 101. At this time, high-pressure air is conveyed into the air flow pipe 201 by an air compressor in the prior art. The high-pressure air enters the air flow pipe 201 from the top of the air flow pipe 201 and flows downward. When the high-pressure air passes through the rotating plate 204, the air flow will not generate a thrust on the rotating plate 204, and the rotating plate 204 remains in a vertical state. Subsequently, the high-pressure air enters a plurality of vertical pipes A501 through the air guide pipe 203 and blows downward onto the formed silicone rubber through the suction cups at the bottom of the vertical pipe B502 to quickly cool the silicone rubber. Then, the cylinder A803 is started. The telescopic end of the cylinder A803 drives the air flow pipe 201 and the installation box 202 to descend through the mounting frame 804. The installation box 202 drives a plurality of vertical pipes A501 to descend through the air guide pipe 203. The vertical pipe A501 drives the vertical pipe B502 to descend through the compression spring A and drives the sleeve 503 to descend through the compression spring B. The distance between the suction cup at the bottom of the vertical pipe B502 and the silicone rubber is shortened. When the suction cup is about to fit with the silicone rubber, the gap between the suction cup and the silicone rubber is small, so that the discharge amount of the high-pressure air through the vertical pipe B502 and the suction cup is reduced. At this time, the air pressure in the air flow pipe 201 increases, and the high-pressure air exerts a backward thrust on the rotating plate 204. The rotating plate 204 presses against the front inclined surface of the elastic limiting block 301 under the action of the force. At this time, the elastic force of the elastic limiting block 301 is greater than the pressing force of the rotating plate 204 on the elastic limiting block 301, and the elastic limiting block 301 will not move, thereby preventing the rotating plate 204 from rotating prematurely, resulting in a reduction in the cooling effect of the high-pressure air on the silicone rubber. Subsequently, the suction cup at the bottom of the vertical pipe B502 contacts and closely fits with the silicone rubber.At this time, the high-pressure air can no longer be discharged through the suction cup of the vertical pipe B502, causing the air pressure in the air flow pipe 201 to increase again. The thrust applied by the high-pressure air to the rotating plate 204 increases. At this time, the squeezing force of the rotating plate 204 on the elastic limit block 301 is greater than the elastic force of the elastic limit block 301. The elastic limit block 301 contracts and slides under the force. Subsequently, the rotating plate 204 passes over the elastic limit block 301 and no longer contacts it. The rotating plate 204 continues to rotate. During the rotation of the rotating plate 204, the rotating plate 204 drives the blocking plate A207 to slide backward through the connecting rod 205 and the sliding rod 206. The sliding rod 206 drives the blocking plate B401 to slide backward through the support rod. After the blocking plate A207 slides, it fits tightly with the inner wall of the air flow pipe 201, blocking the high-pressure air in the air flow pipe 201. The high-pressure air is blocked and flows backward along the inner wall of the air flow pipe 201. After the blocking plate B401 slides, it no longer blocks the connection between the L-shaped pipe 402 and the air flow pipe 201, and at the same time rotates downward to fit with the inner wall of the air flow pipe 201. When the high-pressure air passes through the connection between the L-shaped pipe 402 and the air flow pipe 201, it can generate the Bernoulli effect in the L-shaped pipe 402. A negative pressure is generated in the L-shaped pipe 402, and the air between the air flow pipe 201 and the bottom of the blocking plate A207 is pumped out, and a negative pressure is generated in a plurality of vertical pipes A501 through the air flow pipe 201 and the air guide pipe 203. The vertical pipe A501 generates a negative pressure between the suction cup and the silicone rubber through the vertical pipe B502, so that the suction cup adsorbs the silicone rubber.,

[0029] When the suction cup contacts the molded silicone rubber, the suction cup can press the silicone rubber tightly, and at the same time, the silicone rubber provides support for the vertical pipe B502 through the suction cup, and the telescopic end of the cylinder A803 continues to extend, so that the vertical pipe A501 drops downward relative to the vertical pipe B502, and the compression spring A is forced to shrink. At the same time, the vertical pipe A501 drives the sleeve 503 to drop downward through the compression spring B, and the sleeve 503 drives the round cover 701 and the impeller A702 to drop downward. The impeller A702 drives the two cutting knives 703 to drop downward through the two vertical rods. At this time, the one-way damping plate 601 exerts resistance on the sleeve 503 by rubbing against the inner wall of the sleeve 503, so that the falling speed of the sleeve 503 is slower than the falling speed of the vertical pipe A501, and the distance between the vertical pipe A501 and the bottom of the inner wall of the sleeve 503 is The gap between the two ends is shortened, and the compression spring B is contracted by force, and then the vent B of the sleeve 503 is connected with the vent A of the vertical tube A501. Since there is negative pressure in the vertical tube A501 at this time, after the vent B of the sleeve 503 is connected with the vent A of the vertical tube A501, the air in the round cover 701 is sucked into the vertical tube A501, and the external air enters the round cover 701 through the notch of the round cover 701, and enters the vertical tube A501 through the vent B of the sleeve 503 and the vent A of the vertical tube A501. At this time, the impeller A702 is impacted by the air and rotates with the connection of the sleeve 503 as the center of the circle. The impeller A702 drives the two adjacent cutting knives 703 to move through the two vertical rods. When the cutting knives 703 move, they cut and separate the molded silicone rubber from the waste. The telescopic end of the cylinder A803 no longer extends, so that the vertical pipe A501 no longer falls downward relative to the vertical pipe B502, and the compression spring B is released to drive the sleeve 503 to fall downward relative to the vertical pipe A501, and then the vent B of the sleeve 503 is misaligned with the vent A of the vertical pipe A501, and the inner wall of the sleeve 503 blocks the vent A of the vertical pipe A501, so that the outside air can no longer enter the vertical pipe A501, and the outside air no longer enters the round cover 701, so that the impeller A702 and the cutting knife 703 no longer move, and then the telescopic end of the cylinder A803 is controlled to shrink, and the telescopic end of the cylinder A803 drives the airflow pipe 201 and the installation box 202 to lift and reset through the installation frame 804, and the installation box 202 passes through the air guide pipe 20 3 drives several vertical tubes A501 to be lifted, and the compression spring A is released to lift the vertical tube A501 relative to the vertical tube B502. The vertical tube A501 drives the sleeve 503 to be lifted relative to the vertical tube B502 through the compression spring B, and the sleeve 503 drives the round cover 701 and the impeller A702 to be lifted upward. The impeller A702 drives the two cutting knives 703 to be lifted upward through the two vertical rods until the compression spring A is completely released. At this time, the vertical tube A501 drives the vertical tube B502 to be lifted upward through the compression spring A, and the vertical tube B502 absorbs the silicone rubber through the suction cup, driving the silicone rubber to separate from the molding cavity of the molding mold 101 until the telescopic end of the cylinder A803 is completely retracted and reset, thereby completing the cutting and separation of the molded silicone rubber and the waste, and taking out the silicone rubber. Example 2

[0030] As shown in Figure 10 Figure [5], the cleaning mechanism further includes an elastic baffle 908. One side of the collection box 906 is horizontally and slidably connected through the elastic baffle 908. The elastic baffle 908 is used to block the waste in the collection box 906 to prevent the waste from falling when the collection box 906 moves.

[0031] As shown in Figure 9 Figure [6], it further includes a torsion rod 1001. The top inner walls of the three vertical pipes C902 are fixedly connected with the torsion rod 1001. A friction disc 1002 is slidably sleeved on the outer wall of the torsion rod 1001. A compression spring D is arranged between the friction disc 1002 and the inner wall of the vertical pipe C902. The top end of the sliding pipe 903 is fixedly connected with a friction ring 1003. The friction disc 1002 and the friction ring 1003 are used in cooperation. When the torsion rod 1001 descends relative to the friction disc 1002, the friction disc 1002 can drive the sliding pipe 903 to move through the friction ring 1003. Both the friction disc 1002 and the friction ring 1003 are movably connected to the inner wall of the vertical pipe C902.

[0032] As shown in Figure 11 And Figure 12 Figure [7], it further includes an air guide box 1101. The rear end of the air flow pipe 201 is communicated with the air guide box 1101. The bottom of the mounting frame 804 is fixedly connected with a collection box 1102. The air guide box 1101 and the collection box 1102 are fixedly connected. An impeller B1103 is rotatably connected to the inner wall of the air guide box 1101. A brush roller 1104 is rotatably connected to the inner wall of the collection box 1102. The rotating shaft of the brush roller 1104 rotatably penetrates the air guide box 1101 and is fixedly connected to the impeller B1103 in a penetrating manner. When the impeller B1103 is impacted by high-pressure air, it can drive the brush roller 1104 to rotate.

[0033] Note: The "Figure [5]", "Figure [6]" and "Figure [7]" in the translation are placeholders for the actual figure numbers in the original Chinese text which are not provided completely in the given content. You may need to replace them with the correct figure numbers according to the actual situation.Initially, the telescopic end of cylinder B901 is in a contracted state. When the mounting bracket 804 moves forward, it drives cylinder B901 and the collection box 1102 to move. When high-pressure air flows backward along the air flow pipe 201, the high-pressure air enters the air guide box 1101 and impacts the impeller B1103. The impeller B1103 rotates around the connection point of the air guide box 1101 under the force, and drives the brush roller 1104 to rotate. After taking out the silicone rubber, continue to control the sliding bracket 802 to move forward through the electric guide rail 801. The sliding bracket 802 drives the mounting bracket 804 to move forward through cylinder A803. The mounting bracket 804 drives the air flow pipe 201 and the mounting box 202 to move forward, so that the vertical pipe B502 adsorbs the silicone rubber and moves forward through the suction cup. At the same time, the mounting bracket 804 drives cylinder B901 and the collection box 1102 to move forward. The telescopic end of cylinder B901 drives three vertical pipes C902 to move forward through the support plate. The vertical pipe C902 drives the conical platform 904 and the two adjacent sliding rods 905 to move forward through the sliding pipe 903 until the center of the conical platform 904 is aligned with the center of the forming cavity corresponding to the first row from back to front of the forming die 101. The electric guide rail 801 controls the sliding bracket 802 to stop moving, so that cylinder B901 no longer drives the three vertical pipes C902 to move forward through the support plate. Then start cylinder B901. The telescopic end of cylinder B901 drives the three vertical pipes C902 to descend through the support plate. The vertical pipe C902 drives the corresponding sliding pipe 903 to descend. The sliding pipe 903 drives the conical platform 904 and the two sliding rods 905 to descend. Subsequently, the conical platform 904 contacts the bottom of the forming cavity corresponding to the forming die 101. The forming die 101 provides support for the conical platform 904, so that the conical platform 904 no longer moves. The telescopic end of cylinder B901 continues to extend and drives the three vertical pipes C902 to continue to descend through the support plate. The vertical pipe C902 and the sliding pipe 903 descend relative to the conical platform 904. The sliding pipe 903 drives the two sliding rods 905 to descend. The bottom ends of the sliding rods 905 are squeezed by the outer wall of the conical platform 904, so that the two sliding rods 905 drive the collection boxes 906 thereon to move away from each other. The collection box 906 drives the peeling knife 907 to move. It should be noted that the elastic force of the compression spring D is greater than that of the compression spring C. During the sliding of the sliding rod 905, the compression spring C is compressed under force, and the compression spring D remains in a released state until the bottom surfaces of the sliding rod 905, the collection box 906 and the peeling knife 907 all contact the bottom of the forming cavity of the forming die 101. At this time, the peeling knife 907 contacts the side wall of the forming cavity of the forming die 101. The sliding rod 905 provides support for the sliding pipe 903, so that the sliding pipe 903 cannot continue to descend. The vertical pipe C902 continues to descend and drives the torsion rod 1001 to descend. The gap between the top of the inner wall of the vertical pipe C902 and the top of the friction disk 1002 is reduced. The compression spring D is compressed under force. When the torsion rod 1001 descends, the friction disk 1002 rotates under the action of the torsion rod 1001 and drives the sliding pipe 903 to rotate by friction with the friction ring 1003.The sliding tube 903 drives two sliding rods 905 to revolve counterclockwise around the center of the sliding tube 903. The sliding rods 905 drive the stripping knife 907 to move quickly through the collection box 906. At this time, the elastic baffle 908 slides and extends under the influence of inertia and no longer fits against the inner wall of the collection box 906. When the stripping knife 907 rotates, it can strip the waste remaining on the side wall of the forming cavity of the forming die 101. The waste can enter the collection box 906 along the arc surface of the stripping knife 907 until the telescopic end of the cylinder B901 no longer extends, and then the stripping knife 907 stops moving. At this time, the elastic baffle 908 no longer slides and resets under the influence of inertia. After the elastic baffle 908 resets, it fits against the inner wall of the collection box 906, thereby blocking the waste in the collection box 906 to prevent the waste from falling out of the collection box 906. Then, control the telescopic end of the cylinder B901 to contract. The telescopic end of the cylinder B901 drives three vertical tubes C902 to lift through the support plate. The compression spring D is released, and the torsion rod 1001 lifts upward relative to the friction disc 1002, increasing the gap between the vertical tube C902 and the friction disc 1002. The friction disc 1002 rotates in the opposite direction under the action of the torsion rod 1001. The friction disc 1002 rubs against the sliding tube 903, causing the sliding tube 903 to drive the collection box 906 and the stripping knife 907 to rotate in the opposite direction through the sliding rods 905. The elastic baffle 908 remains in contact with the inner wall of the collection box 906 until the compression spring D resets. The vertical tube C902 continues to lift and drives the friction disc 1002 and the friction ring 1003 to lift. The friction ring 1003 drives two sliding rods 905 to lift upward through the sliding tube 903. The compression spring C is released, causing the two sliding rods 905 to slide closer to each other. The sliding rods 905 drive the stripping knife 907 to move through the collection box 906. At the same time, the bottoms of the two sliding rods 905 jointly squeeze the inclined surface of the frustum 904, preventing the frustum 904 from lifting upward until the compression spring C is completely released. The sliding tube 903 continues to lift and drives the frustum 904 to lift and reset. Then, control the sliding frame 802 to move forward again through the electric guide rail 801, so that the center of the frustum 904 is aligned with the center of the forming cavity corresponding to the second row from the back to the front of the forming die 101. Control the sliding frame 802 to stop moving through the electric guide rail 801. Then start the cylinder B901 and repeat the above steps to achieve the same effect until the forming cavities of the three rows of forming dies 101 are all cleaned. Thus, the cleaning of the forming cavities of the forming die 101 is completed, preventing waste from remaining in the forming cavity and causing the quality of the silicone rubber formed next time to decrease.,

[0034] Then continue to control the sliding frame 802 to move forward through the electric guide rail 801, so that the brush roller 1104 contacts the surfaces of the collection box 1102 and the forming die 101. The bottom surface of the collection box 1102 can scrape off the waste residues on the top surface of the forming die 101, and the rotation of the brush roller 1104 can sweep the waste residues on the top surface of the forming die 101 obliquely upward to the rear side into the collection box 1102. Thus, the forming die 101 can be further cleaned until the rear side of the installation box 202 passes over the front side of the forming die 101. At this time, the air compressor no longer conveys high-pressure air into the air flow pipe 201, and further, the vertical pipe B502 no longer adsorbs the silicone rubber through the suction cup. After the silicone rubber is released from the negative pressure effect, it falls into a pre-prepared hopper. The rotating plate 204 is no longer affected by the high-pressure air, and the torsion spring releases to drive the rotating plate 204 to rotate upward. The rotating plate 204 drives the blocking plate A207 to slide forward through the connecting rod 205 and the sliding rod 206, and the sliding rod 206 drives the blocking plate B401 to slide forward through the support rod. After the blocking plate A207 slides, it no longer fits the inner wall of the air flow pipe 201. Subsequently, the rotating plate 204 contacts and presses the rear inclined surface of the elastic limit block 301. Due to the inclined surface characteristics of the elastic limit block 301, at this time, the elastic limit block 301 is stressed and contracts and slides until the rotating plate 204 passes over the rear inclined surface of the elastic limit block 301, and the elastic limit block 301 releases and slides. After the blocking plate B401 slides, it blocks the connection between the air flow pipe 201 and the L-shaped pipe 402. Then, control the sliding frame 802 to slide backward and reset through the electric guide rail 801, so as to reset the whole device.
