[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be noted that, in the absence of conflict, the embodiments in this disclosure and the feature vectors in the embodiments can be arbitrarily combined with each other.

[0044] In the related art, the molded parts are prone to displacement, pulling deformation and stacking during the movement process. Since the molded parts cool down too quickly and are usually moved or placed manually, the operation is time-consuming and labor-intensive, resulting in low work efficiency and poor quality of the molded composite material sheets.

[0045] In order to solve the problems existing in the related technology, the embodiment of the present disclosure provides a compression molding device for producing molded parts. The compression molding device includes a drying section, a conveying section and a molding mold. The conveying section is used to convey the parts to be produced. Along the conveying direction of the conveying section, the conveying section passes through the drying section. The conveying section has a loading area and a drying area connected in sequence. The molding mold is arranged on a side of the drying section away from the loading area, wherein the conveying section is slidably connected to the drying section, and the sliding direction is parallel to the conveying direction. When the conveying section is in a first preset position, the drying section is opposite to the drying section; when the conveying section is in a second preset position, the drying section moves toward the molding mold so as to be staggered with the drying section. In the present disclosure, during the process of transferring the workpiece to the forming mold after drying, the conveying part first approaches the forming mold, then moves in the direction away from the forming mold and continues to convey the dried workpiece to be made. On the one hand, while conveying the dried workpiece to be made, the workpiece to be made placed in the loading area can be conveyed toward the drying part, thereby saving the transmission time of the workpiece to be dried and improving work efficiency. On the other hand, the friction between the dried workpiece to be made and the conveying part when unloading is reduced, thereby reducing the wear of the conveying part and the workpiece to be made, saving costs and ensuring the quality of the workpiece to be made.

[0046] In order to make the purpose, technical solution and beneficial effects of the embodiment of the present disclosure more clear, a molding device provided by the embodiment of the present disclosure is described in detail below in conjunction with the accompanying drawings. According to the disclosed exemplary embodiment, Figures 1 to 10 As shown, a molding device is shown, which is used to produce a molded part formed by molding a workpiece 7 to be manufactured. The workpiece 7 to be manufactured is used to prevent the penetration of other substances and protect the mechanical equipment from the influence of the external environment. The material of the workpiece 7 to be manufactured can be a sheet material or a rubber material. In one example, the workpiece 7 to be manufactured can be a continuous fiber composite material plate with high strength and high toughness, which is dried and molded to form a molded part. Figure 1 and Figure 2 As shown, the compression molding device includes a drying section 1, a conveying section 2 and a molding die 5. The conveying section 2 is used to convey the workpiece to be manufactured, and the workpiece to be manufactured is the workpiece 7 to be manufactured. The conveying section 2 is conveyed along the conveying direction of the conveying section 2 (such as Figure 1 The conveying part 2 passes through the drying part 1, and the conveying part 2 is used to convey the workpiece 7 to be made. The conveying part 2 has a drying area 3 and a loading area 4 connected in sequence. The loading area 4 is located on one side of the drying area 3, and the forming mold 5 is arranged on the side of the loading area 4 away from the drying area 3, wherein, as shown in FIG. Figure 1 , Fig. 9 and Fig.10 As shown, the conveying part 2 is slidably connected to the drying part 1, and the sliding direction (x direction as shown in the figure) is parallel to the conveying direction (x direction as shown in the figure). When the conveying part 2 is in the first preset position, as shown in Fig. 9 As shown, the drying area 3 is directly opposite to the drying section 1, so that the plurality of to-be-made pieces 7 (such as Fig. 9 As shown in the figure, the second workpiece 7b) is moved to the position opposite to the drying section 1 for drying. When the conveying section 2 is at the second preset position, as shown in the figure, Fig.10 As shown, the drying zone 3 moves toward the forming mold 5, that is, along Fig.10 The feeding area 4 and the drying section 1 are staggered so that the drying section 1 can continue to dry the next piece 7 after drying one piece 7 to be made, that is, Fig. 9 As shown, the workpiece 7 to be made includes a first workpiece 7a to be made, a second workpiece 7b to be made, a third workpiece 7c to be made, and a fourth workpiece 7d to be made. During the compression molding process, the fourth workpiece 7d to be made is first placed in the loading area 4 to form a third workpiece 7c, and then transported to the drying section 1 through the conveying section 2 to form a second workpiece 7b to be made. The dried second workpiece 7b to be made continues to be moved through the conveying section 2 to approach the forming mold 5 to form the first workpiece 7a, and finally compression molding is performed. During this process, the continuous conveying section 2 circulates along the direction I shown in the figure, thereby saving time and improving work efficiency. The conveying section 2 is connected to the drying section 1 by sliding, and can adjust the position of the conveying section 2 or the drying section 1 according to the required movement during the compression molding process, so that the unloading and drying of the workpiece 7 to be made are carried out simultaneously, thereby improving work efficiency.

[0047] During the operation of the molding device, the workpiece 7 to be manufactured is placed in the loading area 4 and conveyed along the conveying direction of the conveying part 2 (such as Figure 1 When the workpiece 7 to be manufactured is transported to the drying area 3, it is dried by the drying section 1, and then transferred to the forming mold 5 by the conveying section 2 for compression molding. At the same time, the sliding drying section 1 or the conveying section 2 continues to transport and dry the next workpiece 7 to be manufactured, wherein the height of the loading area 4 is higher than the height of the lower mold 51 of the forming mold 5, so that it is convenient for the workpiece 7 to be manufactured to move from the conveying section 2 to the forming mold 5, thereby realizing subsequent compression molding.

[0048] In the present disclosure, during the process of transferring the workpiece to the forming mold after drying, the conveying part first approaches the forming mold, then moves in the direction away from the forming mold and continues to convey the dried workpiece to be made. On the one hand, while conveying the dried workpiece to be made, the workpiece to be made placed in the loading area can be conveyed toward the drying part, thereby saving the transmission time of the workpiece to be dried and improving work efficiency. On the other hand, the friction between the dried workpiece to be made and the conveying part when unloading is reduced, thereby reducing the wear of the conveying part and the workpiece to be made, saving costs and ensuring the quality of the workpiece to be made.

[0049] In some embodiments, Figure 1 and Figure 4As shown, the conveying part 2 includes a conveying bracket 21 and a translation driving mechanism 22. A roller is provided at the bottom of the conveying bracket 21 to support and guide the conveying of the workpiece 7 to be manufactured. The driving direction of the translation driving mechanism 22 (such as Figure 1 The x direction shown in Figure 1 The translation drive mechanism 22 may be a chain drive mechanism, an electric drive mechanism, or a pneumatic drive mechanism. In one example, Figure 1 , Fig. 9 and Fig.10 As shown, the translation drive mechanism 22 is a chain transmission mechanism, the first end 221 of the chain transmission mechanism is connected to the drying part 1, and the second end 222 is connected to the conveying bracket 21, ensuring the connection between the two, so that the chain transmission mechanism can drive the drying part 1 or the conveying part 2. For example, when performing molding and conveying, the translation drive mechanism 22 drives the conveying part 2 to approach or move away from the molding mold 5, so that multiple pieces 7 to be produced can be molded. For another example, the translation drive mechanism 22 drives the drying part 1 along the conveying direction (such as Figure 1 When the drying section 1 moves in the x direction (as shown in FIG. 1 ), the drying section 1 can continuously dry the workpieces 7 to be manufactured on the conveying section 2 one by one, thereby improving the drying efficiency.

[0050] In some embodiments, Figures 1 to 10 As shown, the conveying part 2 also includes a chain transmission mechanism 23 and a plurality of support rods 241. The chain transmission mechanism 23 is installed on the conveying bracket 21. The chain transmission mechanism 23 includes a plurality of chain links connected end to end. The plurality of support rods 241 are arranged along the chain links (such as Figure 1 The ends of each support rod 241 are connected to the chain link, and the multiple support rods 241 form a mesh support structure 24, which is used to support the workpiece 7 to be manufactured. In one example, continue to refer to Figures 1 to 10 The chain transmission mechanism 23 is composed of a chain 231 formed by a plurality of chain links, a sprocket 232 and a roller 233. The chain transmission mechanism 23 is located on the conveying part 2. The mesh support structure 24 is wound around the chain 231. During the conveying process of the workpiece 7 to be manufactured, the roller 233 rolls so that the mesh support structure 24 moves along the conveying part 2. Fig. 9 The mesh support structure 24 is connected to the chain transmission mechanism 23, and the connection method can be adaptively set according to the needs. In one example, as shown in FIG. Figure 3 and Figure 4As shown, the mesh support structure 24 is detachably connected to the chain transmission mechanism 23. During the molding process, the mesh support structure 24 can be removed to facilitate inspection and maintenance of the conveying part 2 or the mesh support structure 24, or the mesh support structure 24 can be set with appropriate spacing according to the performance of the workpiece 7 to be manufactured, thereby ensuring the normal operation and safety of the device.

[0051] In some embodiments, the plurality of support rods 241 form a plurality of spaced mesh support structures 24. In one example, continue to refer to Figure 4 , multiple mesh support structures 24 are arranged at intervals on the conveying part 2, so that a workpiece 7 to be manufactured can be placed on each mesh support structure 24, thereby avoiding stacking of multiple workpieces 7 to be manufactured, and the mesh support structure 24 is also breathable. During the molding process, when the workpiece 7 to be manufactured moves to the drying area 3, the drying part 1 can evenly and quickly dry the workpiece 7 to be manufactured on the mesh support structure 24, and the mesh support structure 24 is made of stainless steel and has a Teflon coating on the surface, which is convenient for preventing the workpiece 7 to be manufactured from sticking after drying, thereby improving the timeliness and quality of drying.

[0052] In some embodiments, Figure 3 and Figure 4 As shown, a positioning block 25 is arranged between at least one group of two adjacent support rods 241. The top surface of the positioning block 25 is higher than the top surface of the mesh support structure 24. The positioning block 25 is used to limit the position of the workpiece 7 to be manufactured to avoid displacement or stacking during the transportation of the workpiece 7. The shape structure of the positioning block 25 can be a square structure, a round structure, etc., and can be adaptively set as needed. In one example, continue to refer to Figure 3 The positioning block 25 is a cubic structure, one end of which is connected to the mesh support structure 24 and along the height direction of the conveying part 2 (such as Figure 3 The top surface height of the positioning block 25 is higher than the top surface height of the mesh support structure 24, so that the workpiece to be manufactured can be clamped between the plurality of positioning blocks 25. Fig. 9 When the third workpiece 7c shown in FIG. 1 is placed in the loading area 4 of the conveying part 2, the conveying direction of the conveying part 2 (such as Figure 3 The positioning blocks 25 are arranged at the edges of both sides of the workpiece 7 to be manufactured to prevent the workpiece 7 from moving, and the plurality of positioning blocks 25 are detachably connected to the mesh support structure 24, that is, the positions of the plurality of positioning blocks 25 can be adaptively adjusted according to the size of the workpiece 7 to be manufactured, so that the workpiece 7 to be manufactured is located between the plurality of positioning blocks 25 and is mutually engaged, so as to prevent the workpiece 7 to be manufactured from being displaced and stacked during transportation.

[0053] It should be noted that the number of the positioning blocks 25 can be six or eight, as long as the position of the workpiece 7 can be limited to be difficult to move. In this regard, the present disclosure does not impose too many restrictions. During the molding process, the chain transmission mechanism 23 repeatedly rotates to allow the mesh support structure 24 to continuously move along the conveying direction of the conveying part 2 (such as Figure 1 The operator can continuously place the workpieces 7 to be manufactured on the conveying portion 2 and fix them with a plurality of positioning blocks 25 to prevent the workpieces 7 from being deformed or stacked, thereby realizing continuous compression molding of a plurality of workpieces 7 to be manufactured, thereby improving work efficiency.

[0054] In some embodiments, Figure 1 and Figure 2 As shown, the drying area 3 is provided with a first lifting component 31, and the first lifting component 31 is located on the mesh support structure 24. The first lifting component 31 is used to support the molded parts so that the workpiece 7 to be made extends into the drying section 1. During the molding process, the bottom surface of the workpiece 7 to be made contacts with the top surface of the first lifting component 31, and the contact surfaces are both flat. When drying the workpiece 7 to be made, the first lifting component 31 can be adjusted to make the workpiece 7 to be made close to or away from the drying area 3, thereby improving the drying efficiency. At the same time, the first lifting component 31 is located on the mesh support structure 24 and can also be used to support the workpiece 7 to be made. During drying, the top and bottom surfaces of the workpiece 7 to be made can contact the air with the maximum area, thereby accelerating the circulation of air, so that the workpiece to be made can be dried with the help of external airflow, and the drying effect can be improved.

[0055] In some embodiments, Figure 1 and Figure 5 As shown, the drying section 1 includes a bracket 11, a second lifting assembly 13 installed on the bracket 11, and an oven 12. The bracket 11 is arranged on both sides of the conveying section 2, and the oven 12 is installed along the thickness direction of the conveying section 2 (such as Figure 5 The oven 12 is arranged at intervals in the z direction as shown in the figure, that is, the oven 12 includes an upper oven 121 and a lower oven 122, the upper oven 121 is located on the top surface of the conveying part 2, and the lower oven 122 is located on the bottom surface of the conveying part 2, and the upper and lower ovens 12 are arranged opposite to each other, and the second lifting assembly 13 is installed between the bracket 11 and the oven 12, and the oven 12 is moved along the height direction of the drying part 1 (as shown in the figure) by the second lifting assembly 13. Figure 1 The second lifting assembly 13 may be a lifting column, a lifting rail or a lifting controller, etc. The oven 12 is moved along the thickness direction of the drying section 1 (as shown in the z direction) away from or close to the conveying section 2 through the second lifting assembly 13. Figure 5 In the z direction shown in FIG. 2 , the conveying portion 2 is moved away from or close to the conveying portion 2. In one example, continue to refer to Figure 5The second lifting assembly 13 may be a lifting pulley structure, that is, a guide rail is provided on the side of the bracket 11 close to the oven 12, and a pulley is provided on the oven 12 and mounted on the bracket 11 through the pulley, so that the oven 12 can be moved along the height direction of the drying section 1 (such as Figure 5 The distance between the oven 12 and the workpiece 7 to be manufactured is adjusted according to the required distance, so as to achieve the desired drying effect. Figure 5 The oven 12 is provided with baffles 8 on both sides thereof, and the baffles 8 are used to block the heat between the upper oven 121 and the lower oven 122 to prevent the heat from being lost. When the workpiece 7 to be manufactured is transported, the baffles 8 can be moved to the side wall of the upper oven 121, so that the workpiece 7 to be manufactured (refer to Fig. 9 The second workpiece to be manufactured 7b) shown in the figure can be transported to the drying area 3 by the conveying part 2. When the workpiece to be manufactured 7 is dried, the baffle 8 can be located on the side walls of the upper oven 121 and the lower oven 122, and both ends of the baffle 8 are connected to the upper oven 121 and the lower oven 122, so that there is a closed space between the upper oven 121 and the lower oven 122 and the baffle 8, and the workpiece to be manufactured 7 is located in the closed space and undergoes a drying process, thereby improving the drying effect.

[0056] When the workpiece 7 is transferred to the drying section 1 (refer to Fig. 9When the second workpiece to be made 7b) is shown in the figure, the drying time can be 2-3 minutes, and the time can be adaptively set according to the performance of the workpiece to be made 7. For example, when the workpiece to be made 7 is located in the drying area 3 of the conveying part 2, the second lifting component 13 is adjusted to make the upper oven 121 close to the workpiece to be made 7, and the baffle 8 is placed between the upper oven 121 and the lower oven 122, so that the workpiece to be made 7 is placed in a closed space, and the oven 12 is turned on to make the surface temperature of the workpiece to be made 7 rise. The baking time is 2 minutes, so as to achieve the drying effect and efficiency. After the drying is completed, the second lifting component 13 can be adjusted again to make the upper oven 121 away from the workpiece to be made 7, and the baffle 8 is moved to the side wall of the upper oven 121, and the workpiece to be made 7 is conveyed to the molding mold 5 for compression molding to form a molded part, and then The next unloading, conveying and drying process of the workpiece 7 to be made. For example, when the workpiece 7 to be made is located in the drying area 3 of the conveying section 2, the second lifting assembly 13 is adjusted so that the upper oven 121 and the lower oven 122 are close to the workpiece 7 to be made, and the baffle 8 is placed between the upper oven 121 and the lower oven 122, so that the workpiece 7 to be made is placed in a closed space, and the oven 12 is turned on so that the upper and lower surfaces of the workpiece 7 to be made are heated. The drying time can be 3 minutes, thereby achieving the drying effect and efficiency. After the drying is completed, the second lifting assembly 13 can be adjusted again so that the upper oven 121 and the lower oven 122 are away from the workpiece 7 to be made, and the baffle 8 is moved to the side wall of the upper oven 121, and the workpiece 7 to be made is transferred to the molding mold 5 for compression molding, and then the next unloading, conveying and drying process of the workpiece 7 to be made is carried out.

[0057] In some embodiments, Figure 1 and Figure 6 As shown, the compression molding device further includes a mechanical arm 6, which is disposed on a side of the molding die 5 away from the loading area 4, and a clamping mechanism 61 is disposed at the free end of the mechanical arm 6. The mechanical arm 6 can at least drive the clamping mechanism 61 in the conveying direction (such as Figure 6 The gripper mechanism 61 of the robot arm 6 is used to grab the dried workpiece 7 to be made into the molding mold 5 for molding. In one example, Figures 6 to 8 As shown, the robot arm 6 cooperates with the conveying part 2 to grasp and place. When the workpiece 7 to be manufactured is conveyed to a place close to the forming mold 5, the clamping mechanism 61 of the robot arm 6 grasps the workpiece 7 to be manufactured and moves it to the lower mold 51 of the forming mold 5. At this time, the mesh support structure 24 of the conveying part 2 is away from the forming mold 5, and the upper mold 52 is covered on the workpiece 7 to be manufactured, so that the upper mold 52 cooperates with the lower mold 51 and is molded for 2-3 minutes to obtain a molded part.

[0058] In some embodiments, continue to refer to Figure 1 , Figure 6 and Figure 7As shown, the robot arm 6 includes a first cylinder 62 and a second cylinder 63 arranged vertically, the output shaft of the first cylinder 62 is connected to the main body of the second cylinder 63, and the output shaft of the second cylinder 63 is connected to the clamping mechanism 61, and the first cylinder 62 and the second cylinder 63 can drive the clamping mechanism 61 to reciprocate. In one example, Figure 6 and Figure 7 As shown, the first cylinder 62 and the second cylinder 63 are arranged perpendicular to each other, and the first cylinder 62 can be arranged along the height direction of the drying part 2 (such as Figure 6 The position of the clamping mechanism 61 is adjusted to be consistent with the height of the mesh support structure 24, so that it is convenient for the clamping mechanism 61 to grab the workpiece 7 to be manufactured. When the workpiece 7 is close to the molding die 5, the second cylinder 63 can move along the conveying direction (as shown in the z direction) to adjust the position of the clamping mechanism 61 to be consistent with the height of the mesh support structure 24. Figure 6 The clamp mechanism 61 moves in the x direction (as shown in the figure), drives the clamp mechanism 61 to approach and grab the workpiece 7 to be manufactured, places it in the molding die 5 for molding, and then grabs the workpiece 7 to be manufactured and puts it into the storage after molding. Then, the first cylinder 62 and the second cylinder 63 are driven to move the clamp mechanism 61 to the side of the molding die 5 away from the drying area.

[0059] In some embodiments, continue to refer to Figure 1 , Figure 6 and Figure 7 The conveying part 2 also includes an end support plate 9, along the arrangement direction of the plurality of support rods 241 (such as Figure 1 The end support plate 9 is arranged at one end of a plurality of support rods 241, wherein a notch 91 is arranged on a side of the end support plate 9 away from the support rod 241, and the notch 91 exposes at least a portion of the bottom surface of the workpiece 7 to be manufactured and is opposite to the mechanical claw. When the workpiece 7 to be manufactured is close to the molding mold 5 and is located on the end support plate 9, it is convenient for the clamping mechanism 61 of the mechanical arm 6 to clamp the workpiece 7 to be manufactured.

[0060] The working principle of a compression molding device disclosed in the present invention is:

[0061] like Figures 1 to 10As shown, first, the workpieces to be manufactured 7 include a first workpiece to be manufactured 7a, a second workpiece to be manufactured 7b, a third workpiece to be manufactured 7c, and a fourth workpiece to be manufactured 7d. The workpieces to be manufactured 7 are placed in the loading area 4 of the conveying part 2 (refer to Fig. 9 The third workpiece to be manufactured 7c) is shown in the figure, and is fixed on the mesh support structure 24 with a positioning block 25 to prevent the workpiece 7 from moving and stacking during transportation. It should be noted that multiple groups of positioning blocks 25 can be set to continuously fix multiple workpieces to be manufactured 7 and perform compression molding.

[0062] Next, the conveying part 2 or the drying part 1 is moved by the translation driving mechanism 22 for drying. For example, the fixed workpiece 7 to be made is moved along the conveying direction (such as Figure 1 The x direction shown in FIG. 2 is transferred from the loading area 4 to the drying area 3. When the workpiece 7 to be made is in the drying area 3 (refer to FIG. 2 ), the workpiece 7 is transferred from the loading area 4 to the drying area 3. Fig. 9 The second workpiece to be manufactured 7b is shown in the figure, and the two side baffles 8 on the drying section 1 are moved between the upper oven 121 and the lower oven 122, so that the upper oven 121 and the lower oven 122 and the baffles 8 form a closed space, so that the workpiece to be manufactured 7 is located in the closed space and heat loss is avoided during drying, thereby improving the drying efficiency.

[0063] After drying, the baffle 8 is moved to the side wall of the upper oven 121, and the workpiece 7 is transported to a position close to the molding die 5 by the conveying unit 2 again (refer to Fig. 9 As shown in the figure, the second workpiece to be manufactured 7b), at this time, the robot arm 6 located on one side of the forming mold 5 adjusts the required height and position through the first cylinder 62 and the second cylinder 63, so as to grasp the workpiece to be manufactured 7 through the clamping mechanism 61, and at the same time, the translation drive mechanism 22 on the conveying part 2 drives the conveying part 2 away from the forming mold 5.

[0064] Finally, the robot arm 6 places the workpiece 7 to be manufactured on the molding die 5 (refer to Fig.10 The first workpiece to be manufactured 7a) is shown in the figure, and is restored to the initial state by the first cylinder 62 and the second cylinder 63 again, that is, it is located on one side of the molding mold 5, so that the workpiece to be manufactured 7 is located between the upper mold 52 and the lower mold 51, and the molding is carried out for 2-3 minutes to obtain the desired molded part, thereby completing the molding work.
