Description

Technical Field

[0001] The invention relates to the technical field of molding cooling devices, in particular to a molding cooling device for processing automobile sealing strip materials. Background Art

[0002] When processing automobile sealing strips, the raw materials are first mixed in proportion and then sent to the extruder for extrusion molding. After extrusion molding, the automobile sealing strips need to be cooled and molded in time by cooling water. The molding cooling device is usually composed of a cooling box, a material feeding guide roller, an annular cooling component and a water circulation component. For example, the publication number CN108568958A discloses that the molding cooling of the automobile sealing strip is to perform molding cooling on the sealing strip.

[0003] The raw materials of the sealing strip may be contaminated with dust during storage and transportation, and if the mold is not thoroughly cleaned before use, debris, oil and other impurities from the previous processing may remain inside. When the mold is used for a long time, the coating on its surface may fall off, and the resulting debris will be mixed into the sealing strip, so that dust or impurities may adhere to the surface of the sealing strip. When it is cooled by water, the water in the cooling box will be contaminated.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present invention will be further described below in conjunction with the embodiments.

[0040] Example: Refer to Figures 1 to 11 , a molding and cooling device for processing automobile sealing strip materials, comprising:

[0041] Base platform 1;

[0042] An extrusion mechanism 2 is fixed to the inner bottom wall of the base platform 1, and the extrusion mechanism 2 includes a screw extruder 21, the outer surface of the screw extruder 21 is connected to a feed hopper 22, and an extrusion head 23 is fixed to the output end of the feed hopper 22, which is used to extrude and transport rubber raw materials for production;

[0043] A forming mold 3 fixed to the upper end of the base platform 1;

[0044] Cooling mechanism 5;

[0045] A driving mechanism 6 located between the molding die 3 and the cooling mechanism 5;

[0046] The device has a cleaning state and a reset state. The cross sleeve 1 62 and the cross sleeve 4 65 are used to indirectly drive the movable plate 53 and the salvage net plate 54. The cross sleeve 3 64 is used to indirectly drive the push plate 58. Regardless of whether it is in the cleaning state or the reset state, the push plate 58 will move before the movable plate 53 and the salvage net plate 54.

[0047] Further explanation, in order to cool the sealing strip material and clean the impurities, such as Figure 4 As shown, the cooling mechanism 5 includes a cooling box 51, and a large amount of water is stored in the cooling box 51. The sealing strip material formed by the extrusion mechanism 2 and the forming mold 3 will enter the cooling box 51 and be cooled by the water therein. A movable plate 53 is provided in the cooling box 51. Two reciprocating screws 52 connected by belt transmission are rotated in the middle of the cooling box 51. The movable plate 53 is sleeved on the surfaces of the two reciprocating screws 52, and the two ends of the reciprocating screws 52 are in contact with the outer surface of the sealing shell 55 and the inner wall of the cooling box 51. When the two reciprocating screws 52 rotate, the movable plate 53 will move in the cooling box 51. The lower end of the movable plate 53 is rotatably connected to a salvaging net plate 54, and the salvaging net plate 54 will move with the movable plate 53. A sealing shell 55 is fixed in the cooling box 51. After each cleaning, the impurities in the cooling box 51 will be stored in the sealing shell 55.

[0048] Then, a reciprocating screw rod 2 56 is rotatably connected between the sealing shell 55 and the inner wall of the cooling box 51, and a push plate 58 is sleeved on the surface of the reciprocating screw rod 2 56. An emptying component 59 is fixed to the lower end of the cooling box 51. When the salvage net plate 54 and the limit plate 57 contact each other, the salvage net plate 54 will rotate along the axis between it and the movable plate 53, so that the salvage net plate 54 and the limit plate 57 form a sealed cavity. When the push plate 58 moves when resetting, it can push the impurities in the sealed cavity into the sealing shell 55. The emptying component 59 will discharge the impurities in the sealing shell 55 every time the impurities in the water are cleaned. During the normal cooling process of the device, the push plate 58 blocks the feed hole of the sealing shell 55 to keep the sealing shell 55 in a sealed state.

[0049] To further explain, in order to discharge impurities in the sealed housing 55, as Figure 5As shown, the emptying assembly 59 includes a tapered hole 591 opened on the inner bottom wall of the cooling box 51, and the lower end of the cooling box 51 is connected to a drain pipe 592. The impurities stored in the sealing shell 55 can flow out of the cooling box 51 along the tapered hole 591 and the drain pipe 592. A rectangular shell 595 is provided on the lower side of the cooling box 51, and a sealing plate 596 is slidably installed in the rectangular shell 595. When the device is cleaning, the sealing plate 596 will move before the push plate 58 and the movable plate 53. Hydraulic oil is provided in the rectangular shell 595 and the sealing plate 596. An elastic spring 597 is fixed between the sealing plate 596 and the inner wall of the rectangular shell 595, and a steel wire rope 598 is fixed to one end of the sealing plate 596 close to the elastic spring 597.

[0050] Then, one end of the steel wire rope 598 is wound around the outer surface of the cross sleeve 62, and an L-shaped tube 594 that penetrates into the drain pipe 592 is fixed to one end of the rectangular shell 595, and a water retaining block 593 is slid inside the L-shaped tube 594. When the device is being cleaned, the sealing plate 596 in the rectangular shell 595 will move, and the sealing plate 596 will squeeze the elastic spring 597 when moving to deform and shorten it, thereby pulling the L-shaped tube 594 and the hydraulic oil in the rectangular shell 595 to flow, so that the water retaining block 593 moves downward, and the impurities in the sealing shell 55 will flow into the drain pipe 592 to discharge the device. Before the push plate 58 moves, the shortened elastic spring 597 will push the sealing plate 596 and the hydraulic oil therein to reset, so that the conical hole 591 moves upward to keep the cooling box 51 sealed.

[0051] Further explanation, in order to better control the movement of components in the cooling mechanism 5, as Figure 6 and Figure 7 As shown, the driving mechanism 6 includes a support frame 61, in which a cross sleeve 1 62 rotates, a cross sleeve 2 63 rotates at one end of the cross sleeve 1 62, a cross sleeve 3 64 rotates at one end of the cross sleeve 2 63 away from the cross sleeve 1 62, and a cross sleeve 4 65 rotates at one end of the cross sleeve 3 64 away from the cross sleeve 1 62. Damping is provided at the connection between the cross sleeve 1 62, the cross sleeve 2 63, the cross sleeve 3 64 and the cross sleeve 4 65. In other words, there is damping between the cross sleeve 1 62 and the cross sleeve 2 63, there is damping between the cross sleeve 2 63 and the cross sleeve 3 64, and there is damping between the cross sleeve 3 64 and the cross sleeve 4 65. The cross sleeve 2 63 and the cross sleeve 4 65 are connected to a pulley by a one-way bearing, and the one-way bearings of the cross sleeve 2 63 and the cross sleeve 4 65 are in opposite directions. Two mutually meshing bevel gears 66 are provided on the upper side of the cross sleeve 1 62, and the bevel gear 66 close to the cooling box 51 is connected to the reciprocating screw rod 2 56 by a shaft.

[0052] Then, the cross sleeve 1 62 and the cross sleeve 4 65 are both connected to the reciprocating screw rod 2 56 by transmission, the cross sleeve 2 63 and the cross sleeve 4 65 are both connected to one of the bevel gears 66 by belt transmission, the cross sleeve 3 64 is connected to the reciprocating screw rod 1 52 by belt transmission, a motor 67 is provided on one side of the support frame 61, and a transmission assembly 68 is connected to the output end of the motor 67, and the transmission assembly 68 will drive the cross sleeve 1 62, the cross sleeve 3 64, the cross sleeve 2 63 or the cross sleeve 4 65 to rotate in turn;

[0053] Then, because of the one-way bearing, when the transmission assembly 68 drives the cross sleeve 2 63 and the pulley to rotate, the transmission assembly 68 can only drive the cross sleeve 4 65 to rotate, but cannot drive the pulley thereon to rotate. When the device needs to be reset and the motor 67 rotates in the reverse direction, the transmission assembly 68 will first drive the transmission assembly 68 and the pulley thereon to rotate, but cannot drive the pulley on the cross sleeve 2 63 to rotate. A cross rod 69 is fixed at one end of the support frame 61;

[0054] It should be noted that when the device is being cleaned, the motor 67 needs to be started so that the transmission assembly 68 first drives the cross sleeve 1 62 to rotate. The cross sleeve 1 62 will wrap the wire rope 598 around the surface, and the wire rope 598 will pull the sealing plate 596 to move, and then drive the cross sleeve 2 63 and the pulley thereon to rotate, so that the two bevel gears 66 drive the reciprocating screw rod 2 56 in the cooling box 51 to rotate first, and then drive the cross sleeve 3 64 to rotate. The cross sleeve 3 64 will rotate the two movable plates 53 through the belt transmission connection, and finally drive the cross sleeve 4 65 to rotate. Due to the one-way bearing, the two bevel gears 66 will not complete the transmission when the cross sleeve 4 65 rotates;

[0055] Then, when the device is reset, the motor 67 needs to rotate in the opposite direction. At this time, the transmission assembly 68 will first rotate the cross sleeve four 65 and the pulley thereon, so that the two bevel gears 66 drive the reciprocating screw rod two 56 to rotate in the opposite direction, and then drive the two movable plates 53 to rotate in the opposite direction through the cross sleeve three 64, and finally drive the cross sleeve two 63 to rotate. However, due to the one-way bearing, the cross sleeve two 63 cannot drive the two bevel gears 66 to rotate, and the motor 67 will stop rotating before entering the cross sleeve one 62.

[0056] To further explain, in order to drive the components to rotate in sequence, such as Figure 8As shown, the transmission assembly 68 includes an external threaded sleeve 681, which is fixedly connected to the output end of the motor 67, and the inner cavity of the external threaded sleeve 681 is threadedly connected to the internal threaded sleeve 682, and the end of the internal threaded sleeve 682 away from the external threaded sleeve 681 is rotatably connected to a cross 684, and a telescopic tube 683 is fixed between the cross 684 and the external threaded sleeve 681. The cross rod 69 is slidably connected to the internal threaded sleeve 682, and the motor 67 drives the external threaded sleeve 681 to rotate, wherein the cross rod 69 will limit the internal threaded sleeve 682 so that it cannot rotate. Under the action of the threaded connection, the internal threaded sleeve 682 will move in the external threaded sleeve 681, which can drive the cross 684 to move in the cross sleeve 1 62, the cross sleeve 2 63, the cross sleeve 3 64 and the cross sleeve 4 65. When the cross 684 is located in a sleeve, it will drive that sleeve to rotate.

[0057] Further explanation, in order to better reduce the water temperature in the cooling box 51, as Fig. 9 and Fig.10 As shown, it also includes a heat exchange mechanism 4, which includes a heat exchange box 41 fixed to the upper end of the base platform 1, and a cooling device is provided in the heat exchange box 41, which can reduce the water temperature in the heat exchange box 41, and U-shaped tubes 42 connected thereto are symmetrically fixed at both ends of the heat exchange box 41, and a water pump 43 is fixed at the upper end of the heat exchange box 41, and the U-shaped tube 42 away from the water pump 43 is connected to the cooling box 51 through a pipe 1, and the output end of the water pump 43 is connected to the U-shaped tube 42 located on the same side, and the input end of the water pump 43 is connected to the cooling box 51 through a pipe 2, and a filter is provided in the pipe 2;

[0058] Then, a water tank 45 fixed to the upper end of the base platform 1 is provided between the heat exchange box 41 and the forming mold 3. The water tank 45 is connected to the heat exchange box 41 and the cooling box 51. The water tank 45 can add water to the heat exchange box 41 and the cooling box 51. The upper side of the heat exchange box 41 is provided with an air cooling box 46 fixed to one end of the cooling box 51. When the sealing strip is cooled in the cooling box 51, its surface will be stained with cooling water. When passing through the air cooling box 46, the moisture on the surface of the sealing strip can be blown dry. Two heat exchange tubes 44 are fixed in the heat exchange box 41. The heat exchange tubes 44 are connected to the two U-shaped tubes 42. Starting the water pump 43 can draw the water in the cooling box 51 into the two heat exchange tubes 44. The water flowing in the heat exchange tubes 44 will exchange heat with the water in the heat exchange box 41, thereby reducing the water temperature in the entire cooling box 51 and better performing the cooling work.

[0059] The working principle of the present invention is as follows: the rubber raw material is put into the screw extruder 21 through the feed hopper 22, the screw extruder 21 will extrude and transport the raw material, and finally it is extruded and formed through the extrusion head 23 and the forming mold 3 to produce the sealing strip material of the automobile, the sealing strip material with a higher temperature is placed in the cooling box 51, and the water in the cooling box 51 can cool and form the strip material, and the strip material that has been water-cooled in the cooling box 51 will enter the air cooling box 46, and the air cooling box 46 will blow dry the residual moisture on the surface of the strip material, but the surface of the sealing strip material is not clean, and impurities will remain in the water when it is cooled in the cooling box 51. For the subsequent cooling work, it is necessary to clean the cooling box 51;

[0060] Start the motor 67, the motor 67 will drive the external threaded sleeve 681 to rotate, and the cross rod 69 therein will limit the internal threaded sleeve 682 so that it cannot rotate. Under the action of the threaded connection, the internal threaded sleeve 682 will move in the external threaded sleeve 681, which can drive the cross 684 to move in the cross sleeve 1 62, the cross sleeve 2 63, the cross sleeve 3 64 and the cross sleeve 4 65. First, the cross 684 first drives the cross sleeve 1 62 to rotate, and the cross sleeve 1 62 will wrap the wire rope 598 on the surface, and the wire rope 598 will pull the sealing plate 596 to move. When moving, the sealing plate 596 will squeeze the elastic spring 597 to deform and shorten it, and the hydraulic oil in the L-shaped tube 594 and the rectangular shell 595 will flow, so that the water retaining block 593 moves downward, and the impurities in the sealing shell 55 will flow to the discharge device in the drain pipe 592;

[0061] When the cross 684 leaves the cross sleeve 1 62, the shortened elastic spring 597 pushes the sealing plate 596 and the hydraulic oil therein to reset, so that the tapered hole 591 moves upward to keep the cooling box 51 sealed, and then drives the cross sleeve 2 63 and the pulley thereon to rotate, so that the two bevel gears 66 drive the reciprocating screw rod 2 56 in the cooling box 51 to rotate first, and then drives the cross sleeve 3 64 to rotate. The cross sleeve 3 64 will rotate the two movable plates 53 through the belt transmission connection, and finally drives the cross sleeve 4 65 Rotation, due to the one-way bearing, the two bevel gears 66 will not be driven when the cross sleeve 4 65 rotates, that is to say, the reciprocating screw 2 56 will first drive the push plate 58 to move, and then the movable plate 53 can drive the salvage net plate 54 to move. When the salvage net plate 54 and the limit plate 57 contact each other, the salvage net plate 54 will rotate along the axis between it and the movable plate 53, so that the salvage net plate 54 and the limit plate 57 form a sealed cavity, and the impurities in the cooling box 51 will stay in the sealed cavity;

[0062] After the cleaning is completed, the motor 67 needs to drive the external threaded sleeve 681 to rotate in the opposite direction. At this time, the cross 684 will first rotate the cross sleeve four 65 and the pulley thereon, so that the two bevel gears 66 drive the reciprocating screw rod two 56 to rotate in the opposite direction, and the push plate 58 will reset to push the impurities in the sealing cavity into the sealing shell 55, and then drive the two movable plates 53 to rotate in the opposite direction through the cross sleeve three 64 to reset the salvage net plate 54, and finally drive the cross sleeve two 63 to rotate. Due to the one-way bearing, the cross sleeve two 63 cannot drive the two bevel gears 66 to rotate. Before entering the cross sleeve one 62, the motor 67 will be shut down to prevent the water retaining block 593 from moving downward again, so that the water in the sealing shell 55 is discharged, reducing the waste of water resources.

[0063] When the water in the cooling box 51 needs to be cooled down, starting the water pump 43 can draw the water in the cooling box 51 into the two heat exchange tubes 44. The water flowing in the heat exchange tubes 44 will exchange heat with the water in the heat exchange box 41, thereby lowering the water temperature in the entire cooling box 51 and performing the cooling work better. The water tank 45 can add water to the heat exchange box 41 and the cooling box 51.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
