Description

Technical Field

[0001] The present invention relates to the field of rubber vulcanization equipment, and more specifically, to a rubber vulcanization equipment capable of precisely controlling temperature and pressure. Background Art

[0002] Rubber vulcanization equipment is a device used to convert raw rubber into vulcanized rubber with the desired physical properties. The vulcanization process cross-links the rubber molecular chains through chemical reactions, thereby improving the strength, elasticity and durability of the rubber.

[0003] The most important step in the existing rubber vulcanization process is to use a vulcanizer to process the rubber, and the types of vulcanizers include six categories: flat vulcanizers, rubber vulcanizers, vacuum vulcanizers, tire vulcanizers, capsule vulcanizers and belt vulcanizers. Among them, when the rubber vulcanizer vulcanizes the rubber, the vulcanizer and the rubber raw material are first put into the heating chamber together. Under a certain temperature and pressure, the two are melted and mixed, and then transported into the mold through a pipeline. The heating unit above the vulcanizer keeps the two in a stable state until they are formed. Then the mold is manually moved to the cooling unit on the vulcanizer for cooling and shaping. Finally, the mold is removed and opened, the product is taken out, and the rubber vulcanization is completed. During the operation, the rubber product formed in the mold by the heating unit will be scalded by the staff if the manual operation is improper due to the high temperature of the mold itself when moving.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention provides a switching assembly, so that the mold body does not need to be removed from the vulcanizer body, and the mold body can be moved from the position of the heating assembly to the position of the cooling assembly, thereby fundamentally solving the problem that the surface temperature of the mold body is high after the raw materials inside the mold body are formed by the heating assembly, and the working environment of the operator cannot be guaranteed, thereby improving the safety of the vulcanizing equipment during use.

[0018] (2) The present invention provides a material unloading assembly, which cooperates with the limiting effect of the placement table on the mold body, so that the mold body is in a state perpendicular to the horizontal plane when it moves to the electromagnet position, so that the rubber material that has been shaped in the mold body falls due to its own gravity, thereby achieving the effect of automatic unloading.

[0019] (3) The present invention, through the provision of a conductive spring, an upper extrusion plate and a lower extrusion plate, can extrude the mixed material of rubber and vulcanizer after injecting the vulcanized mixed material into the mold body, so that the gas in the mixed material of rubber and vulcanizer is discharged during the molding and shaping process, thereby reducing the bubbles inside the vulcanized rubber product and improving the production quality of the product.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 8A rubber vulcanizing device with precise temperature and pressure control comprises a vulcanizing machine body 1, a heating chamber 11 is fixedly arranged on the vulcanizing machine body 1, a frame 12 is also fixedly arranged on the vulcanizing machine body 1, an operating table 13 is fixedly installed on the frame 12, a shaping unit 2 is arranged on the vulcanizing machine body 1, the shaping unit 2 comprises a cooling component 22, a heating component 23, a placing table 24 and a mold body 3, two groups of electric telescopic rods 21 are fixedly arranged on the vulcanizing machine body 1, the two groups of electric telescopic rods 21 are fixedly connected to the cooling component 22 and the heating component 23 respectively, the placing table 24 is fixedly installed on the frame 12, the mold body 3 is placed on the placing table 24, and a plurality of mounting blocks 25 are fixedly connected to the frame 12 A switching assembly 4 is also fixedly arranged on the frame 12, and the switching assembly 4 can adjust the position of the mold body 3. The switching assembly 4 includes a sprocket 42 rotatably arranged on the mounting block 25, and a chain 41 is sleeved on the sprocket 42. Two groups of chains 41 are arranged on the left and right sides, and the inner side of one group of chains 41 is rotatably connected to the left connecting plate 43, and the inner side of the other group of chains 41 is rotatably connected to the right connecting rod 44. The left connecting plate 43 and the right connecting rod 44 are jointly fixedly connected to the mold body 3, and the inner side of one group of chains 41 is fixedly connected to the discharge chamber 5, and a hose 51 is rotatably inserted on the discharge chamber 5, and a pump body 52 is arranged on the hose 51. The discharge chamber 5 pumps the rubber material into the mold body 3 through the pump body 52.

[0033] The interior of the mold body 3 is divided into three cavities from top to bottom by the upper extrusion plate 82 and the lower extrusion plate 84. The three cavities include an upper slide groove 38, a molding cavity 37 and a lower slide groove 36. A pressure sensor 83 is fixedly installed on the top of the inner wall of the molding cavity 37, and the pressure sensor 83 is electrically connected to the conductive spring 81.

[0034] The discharge chamber 5 is connected to the heating chamber 11 through an external pipeline, wherein a driving motor is fixedly mounted on the outer surface of the two groups of mounting blocks 25 , and the output end of the driving motor is fixedly connected to the sprocket 42 .

[0035] When the rubber vulcanization equipment is working, firstly, vulcanizing agent and rubber raw materials are put into the heating chamber 11. After being processed by the heating chamber 11, the vulcanizing agent and rubber raw materials are mixed and transported to the discharge chamber 5 through the external pipeline. Then, under the action of the pump body 52, the vulcanized rubber raw materials enter the mold through the hose 51. At this time, the operating table 13 controls the electric telescopic rod 21 to work, so that the heating component 23 moves down and clamps the mold body 3 on the placement table 24. The operating table 13 makes the heating component 23 work to heat and mold the vulcanized rubber raw materials inside the mold body 3. At this time, the operating table 13 controls the driving motor to work and drive the sprocket 42 to rotate, and the sprocket 42 drives the chain 41 to work. As the chain 41 works, the left connecting plate 43 and the right connecting rod 44 are connected to the chain 4 The fixed mold body 3 will move with the chain 41. At this time, the mold body 3 will move to the bottom of the placement table 24. At the same time, the operating table 13 controls the electric telescopic rod 21 to extend so as to make the cooling component 22 work, so as to cool the raw materials formed in the mold body 3 and shape the formed raw materials, thereby achieving the purpose of vulcanization and shaping of the rubber. The mold body 3 does not need to be removed from the vulcanizer body 1, and the mold body 3 can be moved from the position of the heating component 23 to the position of the cooling component 22, which fundamentally solves the problem that the surface temperature of the mold body 3 is high after the raw materials inside the mold body 3 are formed by the heating component 23, and the working environment of the operator cannot be guaranteed, so that the safety of the vulcanization equipment is improved when in use;

[0036] It should be noted that: the sprockets 42 and the chains 41 are symmetrically arranged in two groups, and each group of sprockets 42 is driven by a group of driving motors. The heating component 23 and the cooling component 22 are both existing mature technologies, and can achieve the effect of precise temperature control, which will not be described in detail here;

[0037] The type of pump body 52 adopts an electric diaphragm pump. At the same time, regarding the external pipeline connecting the discharge chamber 5 and the heating chamber 11, the external pipeline can be set at a position where there is no sprocket 42 in the chain 41 and connected to the discharge chamber 5 through a gap between the chain 41 and the placement table 24, and then connected to the heating chamber 11 through a main pipeline connected to the external pipeline. This is an effect that can be achieved without complicated labor, so it is not explained in detail here.

[0038] like Figures 1 to 4As shown, the mold body 3 includes an upper mold 31 and a lower mold 34 divided into two parts, and a blanking assembly 7 is arranged on the mold body 3. The blanking assembly 7 includes a left connecting plate 43 fixedly arranged on the inner side of the left limit plate 33, and the inner side of the right connecting rod 44 is fixedly connected to the right limit plate 32. Multiple groups of lower push rods 61 and upper push rods 62 are fixedly arranged on the inner sides of the left limit plate 33 and the right limit plate 32. A sliding cavity 35 is opened inside the upper mold 31 and the lower mold 34 near the left limit plate 33, and a push block 63 is slidably arranged inside the sliding cavity 35. The push rod 61 and the upper push rod 62 respectively penetrate the upper mold 31 and the lower mold 34 and are fixedly connected to the push block 63. The top of the sliding cavity 35 is an inclined surface. The upper push rod 62 close to the right limit plate 32 is fixedly connected to the upper mold 31, and the lower push rod 61 close to the right limit plate 32 is fixedly connected to the lower mold 34. A magnet 65 is slidably installed on the left connecting plate 43, and the left limit plate 33 is slidably connected to the left connecting plate 43. The left connecting plate 43 is fixedly connected to the outer surface of the lower mold 34, and an electromagnet 64 is fixedly installed on the inner side of one of the mounting blocks 25.

[0039] The push block 63 is a T-shaped block, the extended portion of which is located at the connection between the upper mold 31 and the lower mold 34, and the length of the extended portion is greater than the thickness of the inner wall of the slide cavity 35. The inclined surface at the top of the slide cavity 35 guides the T-shaped block.

[0040] Since the left connecting plate 43 and the right connecting rod 44 are rotatably connected with the chain 41, and the mold body 3 is placed on the placement table 24, under the limitation of the placement table 24 on the mold body 3, when the mold body 3 moves with the chain 41, the magnet 65 will always be facing away from the placement table 24, so as to better adapt to the electromagnet 64. After the vulcanized rubber material inside the mold body 3 is shaped under the action of the cooling component 22, the mold body 3 continues to move with the chain 41 until the magnet 65 on the left connecting plate 43 gradually contacts the electromagnet 64. Under the action of the electromagnet 64, according to the principle that like magnets repel each other and opposite magnets attract each other, the magnet 65 gradually moves away from the electromagnet 64, and then the magnet 65 will bring the left limiting plate 33 as shown in FIG. Figure 3 As shown in the figure, the left limiting plate 33 moves to the right through the lower push rod 61 and the upper push rod 62, and the push block 63 moves to the right in the sliding cavity 35. Due to the limiting effect of the top inclined surface of the sliding cavity 35 on the push block 63, the push block 63 moves to the right, which will cause the upper mold 31 to move up and separate from the lower mold 34. At this time, due to the effect of the left connecting plate 43 and the right connecting rod 44, the entire mold body 3 is in a state perpendicular to the horizontal plane. At the same time, the upper mold 31 is separated from the lower mold 34, and the rubber material that has been finalized in the mold body 3 will fall due to its own gravity, realizing the effect of automatic unloading. It is not necessary for technicians to remove the rubber material in the mold body 3, thereby improving the automation process of the vulcanization equipment and improving production efficiency.

[0041] It should be noted that the end of the magnet 65 close to the left connecting plate 43 has the same polarity as the electromagnet 64;

[0042] At the same time, when the push block 63 is Figure 4 During the rightward movement shown in FIG, the push block 63 moves rightward and contacts the shaped rubber material in the mold body 3, thereby pushing the rubber material to loosen the portion where the rubber material adheres to the inner wall of the mold body 3, so that the rubber material can fall better due to its own gravity.

[0043] like Figures 1 to 7 As shown, a limiting slot 77 is provided in the mold body 3, and a guide assembly 6 for assisting material unloading is provided on the mold body 3. The guide assembly 6 includes a slide bar 71 limitedly set in the slot, and the bottom of the slide bar 71 is fixedly connected to the lower mold 34. A tension spring 72 is provided in the limiting slot 77, and the bottom of the tension spring 72 is fixedly connected to the bottom of the limiting slot 77, and the top of the tension spring 72 is fixedly connected to the top of the slide bar 71. The tension spring 72 is sleeved on the outer surface of the slide bar 71, and a plurality of groups of guide slots 39 are provided in the upper mold 31. Each group of guide slots 39 extends from top to bottom to the outside of the upper mold 31, and the upper push rod 62 is slidably set in the guide slots 39.

[0044] Due to the action of the tension spring 72, when the upper mold 31 and the lower mold 34 are separated due to the blanking component 7, the tension spring 72 will first shrink, and the limiting effect of the limiting slide groove 77 on the slide bar 71 can effectively prevent the upper mold 31 from being completely separated from the lower mold 34 and the upper mold 31 from falling, so that the mold body 3 has better stability when in use. At the same time, when the upper mold 31 and the lower mold 34 are separated due to the blanking component 7, the upper mold 31 moves, and the guide slide groove 39 can enable the upper mold 31 to move a sufficient distance so that the rubber material in the mold body 3 leaves the mold body 3, and the lower push rod 61 can prevent the slide bar 71 from falling because it passes through the lower mold 34, thereby ensuring the integrity of the mold body 3 when in use.

[0045] like Figures 1 to 6 As shown, guide slide blocks 76 are slidably arranged inside the guide grooves 39 at both ends of the upper mold 31 and the lower mold 34, and the outer surface of the guide slide block 76 is fixedly connected to the reset spring 75. A reset rod 73 is sleeved inside the reset spring 75. The reset rod 73 is slidably arranged in the guide grooves 39, and the outer end of the reset spring 75 is fixedly connected to the outer surface of the reset rod 73.

[0046] When the lowering assembly 7 works to separate the upper mold 31 from the lower mold 34, the upper push rod 62 and the lower push rod 61 simultaneously move the push block 63 as the left limit plate 33 moves to the right. Figure 3As shown in the figure, the reset rod 73 moves toward the inside of the guide slot 39, and the reset spring 75 contracts. When the mold body 3 continues to move to the position above the placement table 24 along with the chain 41, the magnet 65 gradually moves away from the electromagnet 64, and the contracted reset spring 75 gradually rebounds, thereby causing the reset rod 73 and the left limit plate 33 to move toward the inside of the guide slot 39. Figure 6 As shown in the figure, the left limit plate 33 moves to the right to achieve the reset effect of the reset rod 73. At the same time, since the left limit plate 33 is reset with the slide rod 71 through the lower push rod 61 and the upper push rod 62, the contracted tension spring 72 will also rebound, thereby pulling the upper mold 31 downward and gradually contacting the lower mold 34. The reset spring 75 cooperates with the tension spring 72 to reset the mold body 3 after unloading, further improving the automation effect of the vulcanization equipment when in use and improving production efficiency.

[0047] It should be particularly noted here that a return spring 75 and a return rod 73 are provided in both the upper mold 31 and the lower mold 34 near the left limit plate 33 , and a blanking assembly 7 is provided only on the side near the left limit plate 33 in the mold body 3 .

[0048] like Figure 4 and Figure 7 As shown, the internal sliding seal of the mold body 3 is provided with an upper extrusion plate 82 and a lower extrusion plate 84, the upper extrusion plate 82 is located above the lower extrusion plate 84, and a pressurizing assembly 8 is provided in the mold body 3. The extrusion assembly includes a conductive spring 81 fixedly connected to the inner walls of the upper mold 31 and the lower mold 34, respectively, and the top of the upper extrusion plate 82 and the bottom of the lower extrusion plate 84 are fixedly connected to the conductive spring 81, respectively.

[0049] The hose 51 is connected to the molding cavity 37 , and a plurality of air holes 821 are provided on the upper extrusion plate 82 . A plurality of one-way valves 9 are fixedly provided on the inner wall of the upper slide groove 38 , and the gas in the upper slide groove 38 can flow to the outside of the mold body 3 through the one-way valve 9 .

[0050] The operating platform 13 is electrically connected to the electric telescopic rod 21 , the cooling assembly 22 , the heating assembly 23 , the electromagnet 64 , the pressure sensor 83 , the pump body 52 , the conductive spring 81 and the driving motor.

[0051] When the pump body 52 is working, the mixed material of the vulcanizer and the rubber raw material in the discharge chamber 5 enters the molding cavity 37 through the hose 51, and at the same time, the operating table 13 controls the conductive spring 81 to work, so that the conductive spring 81 contracts. When the molding cavity 37 is filled with the mixed material of the rubber and the vulcanizer, the operating table 13 cuts off the power to the conductive spring 81, and the conductive spring 81 rebounds at this time, and then squeezes the mixed material of the rubber and the vulcanizer through the upper extrusion plate 82 and the lower extrusion plate 84, so that the gas in the mixed material of the rubber and the vulcanizer is discharged to the upper slide 38 through the air hole 821 during the molding and shaping process, and then discharged to the outside of the mold body 3 through the one-way valve 9, so as to reduce the bubbles inside the vulcanized rubber product and improve the production quality of the product;

[0052] When the unloading assembly 7 works to push out the product in the molding cavity 37, due to the elastic force of the conductive spring 81, it will cooperate with the push block 63 to push down the part of the product adhering to the inner wall of the molding cavity 37, so that the product can be unloaded better and the situation of product failure can be reduced;

[0053] At the same time, when injecting material into the molding cavity 37, the pressure of the upper extrusion plate 82 can be transmitted to the operating table 13 according to the pressure sensor 83, and the expansion and contraction amount of the conductive spring 81 can be controlled by the operating table 13, so as to control the amount of material injected into the molding cavity 37, thereby reducing the situation of poor product production quality due to too many bubbles in the material and insufficient amount of injected material, and to a certain extent, it can also improve the production quality of the product;

[0054] It should be noted that the pressure sensor 83 is a piezoresistive pressure sensor 83. Since the temperature of rubber vulcanization is 120 degrees Celsius, the maximum operating temperature of the piezoresistive pressure sensor 83 used here is 200 degrees Celsius, which can ensure the normal use of the pressure sensor 83.

[0055] As long as the air hole 821 is set small enough, the rubber will not flow into the upper chute 38 through the air hole 821 due to its high viscosity after vulcanization, and will only form a structure similar to the tire hair on the car tire, which can be solved by cutting later;

[0056] The reason why the conductive spring 81 contracts after being energized is that when current passes through the spring, the current directions in adjacent coils are the same. According to the principle of the effect of magnetic field on current, parallel currents in the same direction attract each other, causing the spring to contract.

[0057] Usage: When the rubber vulcanization equipment is working, first put the vulcanizer and rubber raw materials into the heating chamber 11. After being processed by the heating chamber 11, the vulcanizer and rubber raw materials are mixed and transported to the discharge chamber 5 through the external pipeline. Then, under the action of the pump body 52, the vulcanized rubber raw materials enter the mold through the hose 51. At this time, the heating component 23 of the operating table 13 moves down, clamps the mold body 3 on the placement table 24, and heats and molds the vulcanized rubber raw materials inside the mold body 3. At this time, the operating table 13 controls the drive motor to work and rotate the sprocket 42, so that the mold body 3 will move with the chain 41.
