Description

Technical Field

[0001] This disclosure relates to the field of tire mold technology, and in particular to a movable mold tread block, a movable mold, and a cleaning method thereof. Background Technology

[0002] Tire molds are key components used in tire vulcanization, determining the tire's quality, performance, and cost. During tire vulcanization, the space between the mold and the tire blank needs to be completely vented through a venting structure; otherwise, it will result in defective tires.

[0003] Currently, the tire industry still uses venting structures for venting. However, with existing venting structures, vulcanized tires retain rubber fibers that need to be removed, affecting the tire's appearance. This led to the development of ventless tire vulcanizing molds. However, after a period of vulcanization, some rubber adheres to the mold, and some even enters the venting gaps during vulcanization, hindering venting. Therefore, regular mold cleaning is necessary. While tires vulcanized using existing venting molds have an aesthetically pleasing appearance and save on rubber, they still suffer from poor venting and cleaning difficulties. Summary of the Invention

[0004] The problem solved by this invention is to provide a movable mold pattern block, a movable mold, and a cleaning method thereof, which can improve or overcome one or more defects of existing movable molds.

[0005] In a first aspect, this disclosure provides a movable mold pattern block for assembling a movable mold. The movable mold pattern block includes fasteners and a plurality of pattern pieces stacked vertically. The fasteners are configured to fasten or loosen the plurality of pattern pieces so that the spacing between two adjacent pattern pieces is adjustable.

[0006] The movable pattern block has an exhaust channel connecting its end face and the inner circumference of each pattern piece. The exhaust channel includes an exhaust gap and a circumferential exhaust groove. The exhaust gap is located between two adjacent pattern pieces and communicates with the inner circumferential surface of the movable pattern block. The exhaust gap is formed when multiple pattern pieces stacked vertically abut against each other. Each pattern piece has a groove extending circumferentially on at least one side. The grooves of two adjacent pattern pieces form the circumferential exhaust groove, which is located outside the exhaust gap.

[0007] Optionally, the fastener includes a tension bolt, a pin, and a fastening bolt. One end of the tension bolt is threaded to one of the two outermost patterned pieces, and the other end is able to abut against the other patterned piece. The pin passes through multiple patterned pieces, and both ends of the pin are provided with the fastening bolt. The fastening bolt is threaded to the pin and can abut against the patterned piece.

[0008] Optionally, the groove includes a bottom surface and two radially spaced side surfaces, with a smooth transition between the bottom surface and the side surfaces.

[0009] In a second aspect, this disclosure provides a movable mold, comprising a plurality of movable mold pattern blocks provided in the first aspect, wherein the venting gap communicates with the inner cavity of the movable mold, and the circumferential venting groove communicates with the outer side of the movable mold.

[0014] The preset time is 3h-5h.

[0015] Optionally, when spraying dry ice onto the inner cavity surface of the movable molded block, the direction of the dry ice sprayed from the dry ice nozzle is perpendicular to the adhesive surface on the inner cavity surface that needs to be cleaned or forms an angle of 0°-30° with the adhesive surface.

[0016] Optionally, the movable mold cleaning method further includes:

[0017] By loosening the movable pattern block multiple pattern pieces with fasteners, a preset distance is achieved between two adjacent pattern pieces;

[0018] The cleaning tool is inserted into the two opposite grooves; the cleaning tool includes a hollow cleaning head that can produce elastic deformation, a handle, and a connecting rod, the two ends of which are respectively connected to the handle and the cleaning head, and the cleaning head can be inserted into the two opposite grooves;

[0019] Drag the cleaning head along the extension direction of the circumferential venting groove to clean the adhesive in the groove.

[0020] Optionally, the process further includes: inserting the cleaning tool into the groove and dragging the cleaning head along the extension direction of the groove.

[0021] Rotate the cleaning head so that the outer wall of the cleaning head is pressed against the wall of the groove.

[0022] Optionally, a spacer is provided on the pin of the movable pattern block, and a spacer is provided between two adjacent pattern blocks. At least one of the two adjacent pattern blocks is provided with a receiving groove that can accommodate the spacer.

[0023] The spacer can be located in the receiving groove so that two adjacent patterned pieces abut against each other, or it can be dislodged from the receiving groove and sandwiched between two patterned pieces, so that there is a preset gap between two adjacent patterned pieces, the preset gap being the thickness of the spacer;

[0024] The movable mold cleaning method also includes:

[0025] By loosening the multiple patterned pieces of the movable patterned block through the fastening bolts and tension bolts, the gap between two adjacent patterned pieces is adjusted so that the spacer is dislodged from the receiving groove;

[0026] Multiple patterned pieces are fastened by fastening bolts, and spacers are sandwiched between two adjacent patterned pieces, so that there is a preset gap between two adjacent patterned pieces, and the preset gap is the thickness of the spacer.

[0027] The cleaning tool is inserted into the groove; the cleaning tool includes a hollow cleaning head that can produce elastic deformation, a handle, and a connecting rod, the two ends of which are respectively connected to the handle and the cleaning head, and the cleaning head can be inserted into the groove;

[0028] Drag the cleaning head along the extension direction of the groove to clean the adhesive inside the groove.

[0029] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0030] The movable mold pattern block provided in this disclosure has a groove on at least one side of each pattern piece, so that the grooves of two adjacent pattern pieces form a circumferential venting groove, which can increase the venting area and effectively prevent the rubber material entering the circumferential venting groove from sticking to the pattern piece and affecting venting, thereby increasing the number of vulcanized tires and improving efficiency; and the first fastener can be provided so that when the movable mold needs to be cleaned, multiple pattern pieces can be loosened by the first fastener, thereby exposing the groove and facilitating cleaning of the groove.

[0051] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0052] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0053] Example 1

[0054] like Figures 1 to 3 As shown, this embodiment of the present disclosure provides a movable mold pattern block 1 for assembling a movable mold. The movable mold pattern block 1 includes a fastener 12 and a plurality of patterned pieces 11 stacked vertically. The fastener 12 can fasten or loosen the plurality of patterned pieces 11 so that the spacing between two adjacent patterned pieces 11 is adjustable. The movable patterned block 1 has an exhaust channel connecting its end face and the inner circumference of each patterned piece 11. The exhaust channel includes an exhaust gap 101 and a circumferential exhaust groove 102. The exhaust gap 101 is located between two adjacent patterned pieces 11 and communicates with the inner circumferential surface of the movable patterned block 1. When multiple patterned pieces 11 stacked on top of each other abut against each other, multiple exhaust gaps 101 are formed. The width of the exhaust gap 101 is preferably 0.005 to 0.05 mm. Each patterned piece 11 has a groove 111 extending circumferentially on at least one side. The grooves 111 of two adjacent patterned pieces 11 form a circumferential exhaust groove 102. The circumferential exhaust groove 102 is located outside the exhaust gap 101.

[0055] It is understandable that by providing a groove 111 on at least one side of each tread plate 11, the grooves 111 of two adjacent tread plates 11 form a circumferential venting groove 102, which can increase the venting area and effectively prevent the rubber material entering the circumferential venting groove 102 from sticking to the tread plate 11 and affecting venting, thereby increasing the number of vulcanized tires and improving efficiency; and by providing fasteners 12, multiple tread plates 11 can be loosened by fasteners 12 when it is necessary to clean the movable mold, so that the spacing between any two adjacent tread plates 11 can be adjusted, thereby exposing the grooves 111 and facilitating the cleaning of the grooves 111.

[0056] Preferably, each patterned piece 11 has a groove 111 on both sides, and the grooves 111 of two adjacent patterned pieces 11 form a circumferential exhaust groove 102, which can further increase the exhaust area and effectively prevent the adhesive material entering the circumferential exhaust groove 102 from sticking to the patterned piece 11 and affecting the exhaust.

[0057] Reference Figure 1 The fastener 12 includes a tension bolt 121, a pin 122, and a fastening bolt 123. One end of the tension bolt 121 is connected to one of the two outermost patterned pieces 11 among a plurality of patterned pieces 11, and the other end can abut against another patterned piece 11. The pin 122 passes through the plurality of patterned pieces 11, and fastening bolts 123 are provided at both ends of the pin 122. The fastening bolts 123 are threadedly connected to the pin 122 and can abut against the patterned pieces 11.

[0058] It is understandable that by setting up the tension bolt 121, pin 122 and fastening bolt 123, the pattern pieces 11 can be fastened. When it is necessary to clean the movable mold pattern block 1, the fastening bolt 123 can be loosened, and then the tension bolt 121 can be tightened to loosen the pattern pieces 11. This allows the two pattern pieces 11 that need to be cleaned to be separated to clean the groove 111. It also avoids the pattern pieces 11 from completely dispersing, which would increase the difficulty of subsequent assembly.

[0059] Furthermore, the fastening bolt 123 can tighten the pin 122, which not only prevents the pin 122 from moving up and down, but also provides a preload to each patterned piece 11, thus improving the fastening effect.

[0060] Furthermore, one of the two outermost patterned plates 11 has a countersunk hole corresponding to the fastening bolt 123 and the tension bolt 121, while the other patterned plate 11 has a countersunk hole corresponding to the fastening bolt 123 and a threaded hole corresponding to the tension bolt 121. By providing countersunk holes, the fastening bolt 123 and the tension bolt 121 can be hidden, avoiding interference between the fastening bolt 123 and the tension bolt 121 and other components of the movable mold.

[0061] Furthermore, the fastener 12 also includes a washer, which is fitted onto the fastening bolt 123 and located between the head of the fastening bolt 123 and the pin 122.

[0062] like Figure 2 As shown, the groove 111 includes a bottom surface and two radially spaced side surfaces, with a smooth transition between the bottom surface and the side surfaces. This design avoids sharp edges between the bottom surface and the side surfaces of the groove 111, facilitating smooth air venting and preventing dead corners within the groove 111 that would make it difficult to clean adhesive. Preferably, the side surfaces are curved.

[0063] like Figure 3 As shown, the patterned plate 11 has a first mounting hole 112 and a second mounting hole 113. A tension bolt 121 passes through the first mounting hole 112, and the first mounting hole 112 on one of the patterned plates 11 is a threaded hole. The aforementioned pin 122 passes through the second mounting hole 113, and the second mounting holes 113 on the two outermost patterned plates 11 are connected to countersunk holes.

[0064] For example, see Figure 3 The movable patterned block 1 includes three tension bolts 121 and six pins 122, and the corresponding patterned plate 11 has three first mounting holes 112 and six second mounting holes 113. Optionally, the number of tension bolts 121 and pins 122 can be set according to actual needs, and the patterned plate 11 is provided with corresponding first mounting holes 112 and second mounting holes 113.

[0065] It should be noted that the first mounting hole 112 and the corresponding countersunk hole form a step, and the head of the tension bolt 121 can press against the step. The second mounting hole 113 and the corresponding countersunk hole also form a step, and the head of the fastening bolt 123 can press against the step.

[0066] Refer again Figure 3 The exhaust channel also includes an axial exhaust channel, which is formed by axial exhaust holes 103 on multiple tread plates 11. The axial exhaust holes 103 are connected to the end face of the movable mold tread block 1. The grooves 111 of the tread plates 11 are connected to their own axial exhaust holes 103, so that during tire vulcanization, gas is discharged through the exhaust gaps 101, the circumferential exhaust grooves 102 and the axial exhaust channel.

[0067] For example, such as Figure 3As shown, the patterned sheet 11 is provided with three axial vent holes 103, two of which are side axial vent holes near the side end face, and the third axial vent hole is the central axial vent hole. Specifically, the axial vent holes 103 are evenly distributed circumferentially, with the side axial vent holes relatively close to the outer circumferential edge of the patterned sheet 11, and the central axial vent hole relatively close to the inner circumferential edge of the patterned sheet 11. The even distribution of the axial vent holes 103 circumferentially facilitates better venting and cleaning effects.

[0068] This disclosure also provides a movable mold, including a plurality of movable mold pattern blocks 1 as described above. The venting gap 101 connects to the inner cavity of the movable mold, and the circumferential venting groove 102 connects to the outside of the movable mold. Specifically, the circumferential venting groove 102 connects to the outside of the movable mold through an axial venting channel.

[0069] This disclosure also provides a method for cleaning movable molds, applicable to the aforementioned movable molds. The method for cleaning movable molds includes:

[0070] Heat the movable patterned block 1 at a preset temperature for a preset time;

[0071] Dry ice is sprayed onto the inner cavity surface of the movable patterned block 1 to cool it down.

[0072] It is understandable that by heating the movable mold pattern block 1, the temperature of the movable mold is increased, and then dry ice is used to rapidly cool the movable mold pattern block 1. The rapid change in temperature difference causes the rubber material to freeze, crack, and burst, thereby cleaning the rubber material without damaging the mold surface.

[0073] It should be noted that the inner cavity surface of the movable mold pattern block 1 is the surface that contacts the blank, which is the cavity surface of the movable mold.

[0074] Furthermore, the preset temperature is 200℃-380℃. Optionally, the preset temperature can be determined according to the degree of adhesion of the adhesive material on the inner cavity surface of the movable molded block 1. The higher the heating temperature, the easier it is to clean. That is, any temperature between 200℃ and 380℃ can be selected, such as 200℃, 230℃, 260℃, 290℃, 320℃, 350℃, or 380℃.

[0075] Furthermore, the preset time is 3h-5h. Optionally, the preset time can be any time between 3h and 5h, such as 3h, 4h, or 5h. Preferably, it is 4h.

[0076] Furthermore, a dry ice machine is used to spray dry ice onto the inner cavity surface of the movable molded block 1, with a pressure selected between 0.5 MPa and 0.8 MPa. Additionally, when spraying dry ice onto the inner cavity surface of the movable molded block 1, the direction of the dry ice sprayed from the nozzle is perpendicular to the adhesive surface of the inner cavity surface that needs to be cleaned, or at an angle of 0° to 30° to the adhesive surface. The aforementioned adhesive surface refers to the surface of the inner cavity surface of the movable molded block 1 that contains adhesive.

[0077] It is understandable that the cleaning effect is best when the direction of the dry ice sprayed from the dry ice nozzle is perpendicular to the adhesive surface. However, when it is not possible to achieve perpendicularity due to space constraints, the direction of the dry ice sprayed from the dry ice nozzle can be set at an angle of 0°-30° to the adhesive surface.

[0078] The above-mentioned method for cleaning movable molds also includes:

[0079] By loosening the multiple patterned pieces 11 of the movable patterned block 1 through the fastener 12, a preset distance m is formed between two adjacent patterned pieces 11; specifically, the tension bolt 121 can be unscrewed, and at least one fastening bolt 123 at both ends of the pin shaft 122 can be unscrewed.

[0080] Insert the cleaning tool 2 into the groove 111; as follows: Figure 4 As shown, the cleaning tool 2 includes a hollow cleaning head 23 that can produce elastic deformation, a handle 21, and a connecting rod 22. The two ends of the connecting rod 22 are respectively connected to the cleaning head 23 and the handle 21. The cleaning head 23 can be placed in the groove 111.

[0081] Drag the cleaning head 23 along the extension direction of the groove 111 to clean the adhesive in the groove 111. This can clean the adhesive in the groove 111 without completely disassembling the multiple patterned pieces 11.

[0082] To achieve a more thorough cleaning, the cleaning head 23 can be repeatedly dragged and slid within the groove 111 several times, thus cleaning multiple grooves 111. During the cleaning process, the removed adhesive falls through the gap between the two patterned pieces 11 or from one end of the groove 111 in the circumferential direction. At this time, the groove 111 penetrates both end faces of the patterned pieces 11 in the circumferential direction.

[0083] Furthermore, the process of inserting the cleaning tool 2 into the groove 111 and dragging the cleaning head 23 along the extending direction of the groove 111 also includes:

[0084] Rotate the cleaning head 23 so that its outer wall presses against the wall of the groove 111. This allows the cleaning head 23 to scrape off the adhesive on the wall of the groove 111 when dragging it.

[0085] Preferably, after rotating the cleaning head 23, the two sides of the cleaning head 23 in the width direction respectively abut against the walls of the two grooves 111, so that the grooves 111 of the two patterned pieces 11 can be cleaned at the same time, thereby improving the cleaning efficiency.

[0086] The handle 21 makes it easy to pick up the cleaning tool 2 and to drag or rotate the cleaning head 23.

[0087] Furthermore, the cleaning head 23 is made of plastic or carbon fiber. This ensures that the cleaning head 23 can undergo elastic deformation and has a certain structural strength, enabling it to effectively remove adhesive.

[0088] Reference Figure 8 The aforementioned cleaning head 23 is a hollow rectangular plate structure, preferably a rounded rectangular plate structure. When cleaning the groove 111, the width direction of the cleaning head 23 is aligned with the circumferential direction of the movable patterned block 1, and the cleaning head 23 is inserted between two adjacent patterned plates 11, such as... Figure 5 and Figure 6 As shown. Then rotate the cleaning head 23 so that both sides of the cleaning head 23 in the width direction respectively abut against the walls of the two grooves 111, as shown. Figure 7 and Figure 8 As shown. Then, drag the cleaning head 23 along the extension direction of the groove 111 to clean the adhesive in the groove 111.

[0089] It should be noted that the aforementioned preset distance is the distance between the walls of the vent gap 101 formed by the two patterned pieces 11. This preset distance is greater than the thickness of the cleaning head 23, while the sum of the preset distance and the depths of the two grooves 111 is less than the width of the cleaning head 23. This allows the cleaning head 23 to extend without making the distance between adjacent patterned pieces 11 too large, and ensures that after rotating the cleaning head 23, both sides of the cleaning head 23 in the width direction abut against the walls of the two grooves 111 respectively. The preset distance m is preferably 1-1.5 mm, and can be set according to actual needs; no specific limitation is made here.

[0090] Optionally, when the circumferential exhaust groove 102 is formed by a groove 111, the aforementioned preset distance is greater than the thickness of the cleaning head 23, and the sum of the preset distance and the depth of the groove 111 is less than the width of the cleaning head 23.

[0091] Furthermore, it is understood that when the cleaning head 23 is located within the groove 111, the connecting rod 22 is positioned between two adjacent patterned plates 11. Thus, during the dragging of the cleaning head 23, the connecting rod 22 can clean the wall surface of the patterned plates 11 that form the venting gap 101. The material of the connecting rod 22 can be the same as or different from that of the cleaning head 23; no specific restrictions are placed here.

[0092] Furthermore, after the adhesive in the groove 111 is cleaned, the multiple pattern pieces 11 of the movable pattern block 1 are tightened by the tension bolt 121, fastening bolt 123 and pin 122, and the cleaning is completed after checking that the assembly is correct.

[0093] By adopting the above-mentioned method for cleaning movable molds, it is easy to clean the movable molds, and the cleaning effect is good, solving the problems of movable molds being difficult to clean and not being cleaned thoroughly. Moreover, using cleaning tool 2 to clean the circumferential venting groove 102 and venting gap 101 lowers the cleaning threshold, requiring only simple training to operate, thus saving cleaning costs.

[0094] Example 2

[0095] The movable mold pattern block of the movable mold provided in this disclosure has a basically the same structure as the movable mold pattern block in Embodiment 1, the difference being: Figure 9 As shown, a spacer 124 is provided on the pin 122, and a spacer 124 is provided between two adjacent patterned pieces 11. At least one of the two adjacent patterned pieces 11 has a receiving groove 114 that can accommodate the spacer 124. The spacer 124 can be located in the receiving groove 114 so that the two adjacent patterned pieces 11 abut against each other, or the spacer 124 can be dislodged from the receiving groove 114 and sandwiched between two patterned pieces 11, so that there is a preset gap between the two adjacent patterned pieces 11, and the preset gap is equal to the thickness of the spacer 124.

[0096] Spacer 124 is fitted onto pin 122 and can rotate relative to pin 122. It is understood that when spacer 124 is within receiving groove 114, two adjacent patterned pieces 11 abut against each other. When fastening bolt 123 and tension bolt 121 loosen the multiple patterned pieces 11, the gap between two adjacent patterned pieces 11 can be adjusted to allow spacer 124 to disengage from receiving groove 114. Subsequently, spacer 124 can rotate to offset from receiving groove 114. After multiple patterned pieces 11 are fixed by fastening bolt 123, spacer 124 is sandwiched between two patterned pieces 11. At this point, there is a preset gap between any two adjacent patterned pieces 11, the preset gap being the thickness of spacer 124, facilitating subsequent cleaning of groove 111 using cleaning tool 2.

[0097] Preferably, such as Figure 9 and Figure 10 As shown, one of two adjacent patterned pieces 11 is provided with the aforementioned receiving groove 114, and the receiving groove 114 is located on the same side of both adjacent patterned pieces 11 (e.g., Figure 9 On the right side of the patterned sheet 11, the receiving grooves 114 all protrude from the second mounting hole 113 towards the cavity side. The thickness of the spacer is t, which is preferably 1-1.5 mm.

[0098] like Figure 11 As shown, after the fastening bolt 123 and the tensioning bolt 121 loosen the multiple pattern pieces 11, the pattern piece 11 is slid to one side with the pattern block cavity surface facing upwards (e.g., Figure 9 (On the right side of the middle), the spacer 124 can detach from the receiving groove 114 and rotate under gravity to the side of the pin 122 away from the cavity surface. After fixing multiple patterned pieces 11 by fastening bolts 123, the spacer 124 is sandwiched between two patterned pieces 11. At this time, the fastening bolts 123 at both ends of the pin 122 have retracted distances L1 and L2 respectively relative to the initial state (the state when multiple patterned pieces 11 are fastened), L1+L2=(N-1)t. Through the pin 122 and the fastening bolts 123 at both ends, the sum of L1 and L2 is large enough to ensure that the patterned blocks will not fall apart and affect reassembly. After cleaning, the patterned block cavity surface can be facing down, and the spacer 124 can rotate under gravity to the side of the pin 122 facing the cavity surface, while the patterned pieces 11 slide towards the other side. The spacer 124 enters the receiving groove 114 and the patterned block is fastened by the tension bolt 121 and the fastening bolt 123.

[0099] Furthermore, at least one of the six pins 122 of the movable mold pattern block 1 is provided with the aforementioned spacer 124. The movable mold cleaning method provided in this disclosure is basically the same as the movable mold cleaning method in Embodiment 1, except for the cleaning method of the groove 111. Specifically, the movable mold cleaning method includes:

[0100] By loosening the multiple pattern pieces 11 of the movable pattern block 1 by tightening bolts 123 and tensioning bolts 121, the gap between two adjacent pattern pieces 11 is adjusted so that the spacer 124 is dislodged from the receiving groove 114.

[0101] Multiple patterned pieces 11 are fastened by fastening bolts 123, and spacers 124 are sandwiched between two adjacent patterned pieces 11, so that there is a preset gap between two adjacent patterned pieces 11, the preset gap being the thickness of the spacer 124.

[0102] The cleaning tool 2 is inserted into two opposite grooves 111; the cleaning tool 2 includes a hollow cleaning head 23 that can produce elastic deformation, a handle 21 and a connecting rod 22, the two ends of the connecting rod 22 are respectively connected to the handle 21 and the cleaning head 23, and the cleaning head 23 can be inserted into two opposite grooves 111.

[0103] Drag the cleaning head 23 along the extension direction of the groove 111 to clean the adhesive in the groove 111.

[0104] Understandably, by setting the spacer 124, the spacer 124 can rotate relative to the pin 122. When the spacer 124 is located in the receiving groove 114, two adjacent patterned pieces 11 abut against each other. When the fastening bolt 123 loosens the multiple patterned pieces 11, the gap between two adjacent patterned pieces 11 can be adjusted so that the spacer 124 is dislodged from the receiving groove 114. Subsequently, the spacer 124 can be rotated to make the spacer 124 and the receiving groove 114 misaligned. After the multiple patterned pieces 11 are fixed by the fastening bolt 123, the spacer 124 is sandwiched between two patterned pieces 11. At this time, there is a preset gap between any two adjacent patterned pieces 11. At this time, the sum of the distances moved by the two fastening bolts 123 compared to when fastening multiple patterned pieces 11 is equal to (N-1) multiplied by the preset gap, where N is the number of spacers 124.

[0105] When cleaning the groove 111, the width direction of the cleaning head 23 is aligned with the circumferential direction of the movable patterned block 1, and the cleaning head 23 is inserted between two adjacent patterned pieces 11, such as... Figure 11 and Figure 12 As shown. Then rotate the cleaning head 23 so that both sides of the cleaning head 23 in the width direction respectively abut against the walls of the two grooves 111, as shown. Figure 13 and Figure 14 As shown. Then, drag the cleaning head 23 along the extension direction of the groove 111 to clean the adhesive in the groove 111.

[0106] It should be noted that the aforementioned preset gap is greater than the thickness of the cleaning head 23, but the sum of the preset gap and the depth of the two grooves 111 is less than the width of the cleaning head 23.

[0107] Furthermore, after the adhesive in the groove 111 is cleaned, the multiple pattern pieces 11 of the movable pattern block 1 are tightened by the tension bolt 121, fastening bolt 123 and pin 122, and the cleaning is completed after checking that the assembly is correct.

[0108] By adopting the above-mentioned method for cleaning movable molds, it is easy to clean the movable molds, and the cleaning effect is good, solving the problems of movable molds being difficult to clean and not being cleaned thoroughly. Moreover, using cleaning tool 2 to clean the circumferential venting groove 102 and venting gap 101 lowers the cleaning threshold, requiring only simple training to operate, thus saving cleaning costs.
