Description

Technical Field

[0001] The invention relates to the technical field of flat plate vulcanizing machines, and in particular to a mold cooling device based on a flat plate vulcanizing machine. Background Art

[0002] Flat plate vulcanizer is a commonly used equipment in the rubber processing industry, mainly used for vulcanizing rubber products. The existing flat plate vulcanizer has improved in automation, and some equipment has realized the automatic feeding and positioning function. This function drives the mold to move by pushing the lower fixed plate through the hydraulic cylinder until it slides to the unloading slide, and then separates the upper and lower molds through the automatic mold turning mechanism to realize the removal of the processed product. After that, the mold is positioned and reset on the lower platform to realize continuous processing.

[0003] However, the existing vulcanizing machines have an efficiency bottleneck during processing. That is, when the mold is unloading, generally after the lower fixed plate is moved to the unloading station, it is necessary to manually blow cold air into the product to cool it down when the mold is opened. The product can only be taken out after cooling down. This manual intervention method not only reduces the processing efficiency of the product, but also affects the continuity and stability of the overall production.

[0004] Based on this, in order to further optimize the loading and unloading efficiency of the feeding and positioning device, we proposed a mold cooling device based on a flat vulcanizing machine. Summary of the invention

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1-11 An embodiment of the present invention discloses a mold cooling device based on a flat vulcanizer. Specifically, the feeding positioning device comprises a lower fixed plate 2, an upper fixed plate 3 and a material unloading slide 4 installed on a lower platform 1. The material unloading slide 4 comprises two support frames. The opposite surfaces of the two support frames are rotatably connected to rollers. The two opposite rollers are used to carry the lower fixed plate 2. The upper fixed plate 3 covers the upper part of the lower fixed plate 2. The lower platform 1 is installed on the inner side of the machine body and is driven up and down by a hydraulic cylinder to achieve hot pressing vulcanization with the upper platform. The specific structure is a conventional solution of personnel in the field, and will not be described in detail here.

[0039] Reference Figure 3In addition, a lower mold 21 and an upper mold 31 are respectively arranged on the opposite surfaces of the lower fixed plate 2 and the upper fixed plate 3. A driving member 5 for driving the lower fixed plate 2 to move toward the unloading slide 4 is also fixedly installed on the side of the lower platform 1. Of course, the driving member 5 described in this embodiment can be a traditional hydraulic cylinder. The hydraulic cylinder pushes the lower fixed plate 2 to move toward one side of the unloading slide 4 to complete the unloading of the vulcanized rubber. After the unloading is completed, the lower fixed plate 2 and the upper fixed plate 3 are pulled back to the lower platform 1 to perform the vulcanization operation after the new material is filled, so as to complete the feeding positioning of the mold;

[0040] Reference Figure 1 , Figure 3 , a floating assembly 6 is provided between the lower fixed plate 2 and the upper fixed plate 3. The floating assembly 6 described in this embodiment is used to keep the lower fixed plate 2 and the upper fixed plate 3 separated in the unpressed state, so that the lower mold 21 and the upper mold 31 are separated and a cooling channel for airflow to pass through is formed. A cooling unit 7 is also slidably connected to one side of the unloading slide 4. The cooling unit 7 is used to provide cold air to discharge the heat in the above cooling channel. A follow-up unit 8 is provided between the cooling unit 7 and the lower fixed plate 2. The follow-up unit 8 is used to keep the cooling unit 7 moving synchronously with the lower fixed plate 2 when the lower fixed plate 2 moves forward to unload the material, so as to realize the cooling operation of the product while moving the unloading. After the lower fixed plate 2 moves to the unloading station, since the product has been fully cooled during the unloading movement, there is no need to perform manual blowing cooling, and the product can be directly taken and the raw materials can be filled, which greatly improves the unloading efficiency and reduces the labor input.

[0041] Reference Figure 3 In some embodiments, the floating assembly 6 of the present invention includes a plurality of sleeves 61 distributed on the lower fixed plate 2, and a plurality of guide rods 62 distributed on the bottom of the upper fixed plate 3. Preferably, the sleeves 61 and the guide rods 62 described in this embodiment are both distributed in a matrix of four;

[0042] The guide rod 62 is inserted into the sleeve 61 , and a first spring 63 is placed between the guide rod 62 and the inner bottom of the sleeve 61 .

[0043] That is, in this embodiment, the guide rod 62 and the sleeve 61 are plugged in, which does not affect the normal pressing and vulcanization operation. In the unloading and loading stages, the first spring 63 provides a thrust to push the upper fixed plate 3 upward, thereby achieving the effect of separating the lower mold 21 and the upper mold 31, so as to facilitate the subsequent blowing and cooling between the lower mold 21 and the upper mold 31, thereby realizing cooling of the product.

[0044] Reference Figure 5Furthermore, the cooling unit 7 in the present invention includes a slide plate 71 slidably connected to the side of the unloading slide 4, the bottom of the slide plate 71 has a slide seat, the slide seat is slidably connected to the profile groove of the unloading slide 4, and two support arms 72 are arranged above the slide plate 71, and the support arms 72 are vertically connected to the top of the slide plate 71;

[0045] A telescopic assembly 73 is disposed above the support arm 72 , and an air pipe 74 is commonly connected between the ends of the two telescopic assemblies 73 . A plurality of air holes 75 are linearly distributed on the end surface of the air pipe 74 .

[0046] Reference Figure 7 On the basis of the above embodiment, the telescopic assembly 73 includes a gas cylinder 731 fixed on the support arm 72. In this embodiment, a connecting seat is fixedly installed on the top of the support arm 72, and the gas cylinder 731 is fixed inside the connecting seat. Specifically, in this embodiment, the gas cylinder 731 is connected to the gas source through a joint;

[0047] A hollow tube 732 is movably inserted inside the air cylinder 731. Of course, a sealing structure such as a sealing ring should be provided at the end of the hollow tube 732 to ensure that there will be no leakage or other problems at the sliding point between the hollow tube 732 and the air cylinder 731. The tail end of the hollow tube 732 is connected to the air pipe 74, and a tension spring 733 is fixedly connected between the hollow tube 732 and the inner wall of the air cylinder 731.

[0048] That is to say, in the present invention, by adopting the design of the retractable air pipe 74, when cooling is not required, the compressed gas does not enter the interior of the air cylinder 731, and the hollow tube 732 drives the air pipe 74 to move backward under the pulling of the tension spring 733, so as to achieve the purpose of not occupying space;

[0049] During the blanking process, when the lower fixed plate 2 slides forward, the gas source on the gas cylinder 731 is turned on, and the hollow tube 732 moves outward under the push of the compressed gas to drive the air pipe 74 to approach one side of the lower mold 21 and the upper mold 31, and at the same time, part of the compressed gas enters the air pipe 74 along the inside of the hollow tube 732 and is discharged through the air hole 75 to achieve air cooling of the product. The movable design can ensure that the air pipe 74 and the mold are at a small distance during cooling, ensuring that the airflow can enter between the lower mold 21 and the upper mold 31 to the maximum extent, so as to avoid the problem of wind energy waste caused by excessive spacing.

[0050] Reference Figure 8 , Fig. 9 It should be noted that the present invention also includes a synchronization mechanism 76, which is installed on the support arm 72 and is used to keep the two hollow tubes 732 moving synchronously.

[0051] Preferably, the synchronization mechanism 76 in this embodiment includes a gear 761, a notch is opened at the upper end of the support arm 72, and the gear 761 is rotatably connected in the notch; a synchronization rod 762 is fixedly connected between two of the gears 761, and the bottom of the hollow tube 732 has a rack portion 763 meshing with the gear 761.

[0052] That is, in the present invention, a rack portion 763 is provided at the bottom of the hollow tube 732. When the compressed gas pushes the hollow tube 732 to move during cooling, the hollow tube 732 engages the rack portion 763 to rotate the gear 761 thereunder. Since a synchronization rod 762 is fixed between the two gears 761, the two hollow tubes 732 on both sides can maintain the effect of moving outward synchronously, thereby avoiding the situation where one side of the hollow tube 732 moves too fast or too slow, causing the two sides of the hollow tube 732 to move out of sync and then get stuck, thereby ensuring the movement stability of the air pipe 74.

[0053] Reference Figure 7 , Fig. 9 On the basis of the above embodiments, considering that the thicknesses of different lower molds 21 and upper molds 31 are different, the center position of the cooling channel formed therebetween will change. Therefore, in order to adapt to products at different heights within a certain range, the upper end of the slide plate 71 in this embodiment has two sleeve frames 711, and the bottom of the support arm 72 is inserted into the sleeve frame 711, wherein the outer side of the sleeve frame 711 is provided with a locking member 712 for locking the support arm 72. Specifically, the locking member 712 described in this embodiment is configured as a bolt, which is threadedly connected to the inner side of the sleeve frame 711, that is, the height of the air pipe 74 is adjusted by movably plugging the support arm 72 with the sleeve frame 711 to meet the cooling requirements of products at different positions and to improve the overall adaptability. After the adjustment is completed, it is only necessary to rotate and lock the above-mentioned locking member 712, which is simple and convenient to operate.

[0054] Reference Figure 6 , Figure 8 , Fig. 9 In some embodiments, the follower unit 8 of the present invention includes a bending plate 81 slidably connected to the slide plate 71. Specifically, the bending plate 81 described in this embodiment is an L-shaped structure, one side of which slides on the outside of the slide plate 71, wherein two slide grooves are provided on the end surface of the bending plate 81, and a guide pin is fixedly installed on the end surface of the slide plate 71, and the guide pin and the slide groove are slidably matched to keep the bending plate 81 sliding up and down;

[0055] Reference Fig. 9 Further, a second spring 82 is fixedly connected between the bending plate 81 and the slide plate 71, referring to Figure 4 , Fig.11 The side of the lower fixed plate 2 is fixedly connected with a front push block 83 and a rear push block 84, the height of the rear push block 84 is smaller than the height of the front push block 83, and a rotation groove is opened on the side of the rear push block 84, in which a rear push rod 841 is rotatably connected through a torsion spring. The rear push rod 841 remains perpendicular to the rear push block 84 in the initial state and can rotate in one direction. In this embodiment, it can rotate toward one side of the front push block 83, and stop the force in the other rotation direction. The bending plate 81 is clamped between the front push block 83 and the rear push block 84.

[0056] Reference Fig.11 Specifically, the forward push block 83 described in this embodiment is used to push the bending plate 81 to move forward synchronously, and the rear push block 84 is used to push the bending plate 81 to move backward synchronously for resetting when the lower fixed plate 2 moves backward and resets to the lower platform 1. Of course, in order to reduce the contact friction between the bending plate 81 and the forward push block 83 and the rear push block 84, two rollers can also be rotatably connected on both sides of the bending plate 81 in this embodiment.

[0057] Reference Figure 5 , Figure 6 Of course, in order to separate the bending plate 81 from the rear push rod 841 during loading, an unlocking block 85 is installed above the unloading slide 4 in this embodiment, and a guide shaft 86 sliding on the unlocking block 85 is fixedly connected to the upper side of the bending plate 81;

[0058] Reference Fig. 9 , wherein the unlocking block 85 includes a guiding slope 851, a parking plane 852 and an unlocking slope 853, and when the rear push rod 841 contacts the bending plate 81 and moves to the unlocking slope 853, it is separated from the bending plate 81.

[0059] In a specific action process, when vulcanization is completed, the driving member 5 first pushes the lower fixed plate 2 to move toward one side of the lower material slide 4. When the lower fixed plate 2 moves forward, its rear push block 84 cannot contact the upper side of the bending plate 81, but the bending plate 81 can contact the rear push rod 841. During the movement, the bending plate 81 contacts the rear push rod 841 and rotates without generating thrust. Thereafter, the front push block 83 contacts the bending plate 81 to drive the entire cooling unit 7 to move forward.

[0060] The slide plate 71 moves forward with the lower fixed plate 2, and at the same time, the guide shaft 86 on the bending plate 81 moves along the parking plane 852 until it slides to the guide slope 851 and is completely separated from the unlocking block 85. At this time, the entire bending plate 81 is clamped between the front push block 83 and the rear push block 84, and completely follows the movement of the lower fixed plate 2. At this time, the air cylinder 731 enters compressed air, and under the push of the compressed air, the air pipe 74 moves outward and approaches the lower mold 21 and the upper mold 31 to realize blowing cooling of the product until the lower fixed plate 2 moves to the unloading station, and the blowing is stopped to complete the cooling operation of the product during the entire positioning and unloading process.

[0061] When the product is removed and new material is filled, the driving member 5 pulls the lower fixed plate 2 backward. At this time, the rear push rod 841 on the rear push block 84 contacts the bending plate 81 to drive it to follow the movement, and the entire cooling unit 7 begins to move backward and reset. When the slide plate 71 moves to the unlocking block 85, the guide shaft 86 will first move upward along the guide slope 851 to the parking plane 852, and the entire bending plate 81 will move upward. When the lower fixed plate 2 moves further, the guide shaft 86 moves to the unlocking slope 853, and the bending plate 81 is further raised until its side is separated from the rear push rod 841. After that, the lower fixed plate 2 is positioned on the lower platform 1, and the guide shaft 86 slides along the unlocking slope 853 and moves down to the parking plane 852 to wait for the next following movement, thereby completing a movement operation of unloading and loading.

[0062] Reference Figure 4 , Figure 6 , Fig. 9 , Fig.11 As a preferred embodiment, considering that the guide shaft 86 is not locked on the parking plane 852 in the non-moving state, it is easy to accidentally touch it and cause it to slide, which in turn easily causes the problem that the subsequent reciprocating movement linkage with the front push block 83 and the rear push rod 841 cannot be achieved. The unlocking block 85 of the present invention slides horizontally above the unloading slide 4 through the third spring 87, and a push rod 88 is fixedly installed on the side of the unlocking block 85. The side of the lower fixed plate 2 is fixedly connected with an inclined top block 89 that resists the movement of the push rod 88. The inclined top block 89 is a structure with inclined surfaces on both sides and a plane in the middle. Through the design of the inclined surfaces on both sides, the inclined top block 89 will not interfere with the push rod 88 in the process of the lower fixed plate 2 moving forward to unload and moving backward to load, and can achieve contact and resistance with the push rod 88.

[0063] Reference Fig. 9, wherein the top of the parking plane 852 also has a stop protrusion 854 for stopping the guide shaft 86. The stop protrusion 854 is set as an inclined surface on one side facing the guide inclined surface 851, and is a plane on the other side. The guide shaft 86 is stopped by the plane to prevent the guide shaft 86 from slipping off the parking plane 852. The side edge of the stop protrusion 854 is at a predetermined distance from the side edge of the parking plane 852 to form a channel for the guide shaft 86 to slide.

[0064] That is, when the lower fixed plate 2 moves backward after loading, when the guide shaft 86 moves along the guide slope 851 to the parking plane 852, it moves further along the slope of the stop protrusion 854 to the rear side of the plane, and when the guide shaft 86 moves to the unlocking slope 853 and unlocking is completed, it will move backward and reset to between the unlocking slope 853 and the stop protrusion 854, so as to prevent the slide plate 71 from being separated from the unlocking block 85;

[0065] Of course, when the lower fixed plate 2 moves forward during unloading, the inclined top block 89 on the side of the lower fixed plate 2 will resist the movement of the push rod 88, and the push rod 88 will drive the entire unlocking block 85 to move laterally until the guide shaft 86 moves to the side of the stop protrusion 854 to complete the unlocking of the guide shaft 86. At this time, the guide shaft 86 can move freely along the above-mentioned channel. When the lower fixed plate 2 moves further, the forward push block 83 on its upper side can drive the bending plate 81 to move, and then drive the slide plate 71 to move synchronously.

[0066] In summary, the present invention adopts a design of a floating component 6 on the lower fixed plate 2 and the upper fixed plate 3 to keep the lower fixed plate 2 and the upper fixed plate 3 separated in the unpressed state, so that the lower mold 21 and the upper mold 31 are separated and a cooling channel for airflow to pass through is formed, and at the same time, cold air is provided by the cooling unit 7 to discharge the heat in the cooling channel. The cooling unit 7 moves synchronously with the lower fixed plate 2 through the follower unit 8 to realize the cooling of the upper mold 31 and the product while moving the material. After the lower fixed plate 2 moves to the material unloading station, since the product has been fully cooled during the material unloading process, there is no need for manual air blowing cooling, and the product can be directly taken and the raw materials can be filled, which greatly improves the material unloading efficiency and reduces the labor input.

[0067] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
