Description

Technical Field

[0001] The present application relates to the field of manufacturing technology, and in particular to a mold platform for foam molding and a foam molding method for vehicle carpet. Background Art

[0002] The vehicle's carpet is an interior component of the vehicle that can absorb water and insulate sound.

[0003] The carpets in many different vehicle models differ only in local areas, which may be different in length or structure. For example, the difference between a five-seater vehicle and a seven-seater vehicle is only the difference in length of the carpet at the rear of the vehicle. Or, for vehicles with the driver's seat on the left or right, only the structure of the carpet at the head of the vehicle is different.

[0004] Usually, even if the difference is only in the above-mentioned local area, the mold of the entire carpet needs to be remade. However, this not only reduces the production efficiency of the carpet and increases the cost, but also takes up more space to store the carpet molds corresponding to various car models, resulting in a waste of resources.

[0050] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0051] The present application embodiment provides a mold platform for foaming molding, such as Figure 1 As shown, the mold platform includes a lower mold main mold frame 1, an upper mold main mold frame 2, multiple lower mold partition molds 3, and multiple upper mold partition molds 4. The lower mold partition molds 3 can be fixedly connected to the lower mold main mold frame 1. The lower mold main mold frame 1 is used to fix and limit the multiple lower mold partition molds 3, so that the multiple lower mold partition molds 3 are connected together to form a lower mold mold for a complete vehicle carpet. Similarly, the upper mold partition mold 4 can be fixedly connected to the upper mold main mold frame 2. The upper mold main mold frame 2 is used to fix and limit the multiple upper mold partition molds 4, so that the multiple upper mold partition molds 4 are connected together to form a upper mold mold for a complete vehicle carpet.

[0052] After the lower mold main mold frame 1, multiple lower mold partition molds 3, upper mold main mold frame 2 and multiple upper mold partition molds 4 are clamped, each lower mold partition mold 3 is matched with an upper mold partition mold 4, and the mold cavity of the entire vehicle carpet is formed between the multiple lower mold partition molds 3 and the multiple upper mold partition molds 4.

[0053] Any set of lower and upper partition molds 3 and 4 can be replaced to suit different vehicle models, creating a mold platform for vehicle carpets corresponding to different vehicle models. This eliminates the need to redevelop and replace molds for the entire vehicle carpet, improving production efficiency and reducing costs. It also reduces the storage space required for molds for different vehicle carpet models, improving resource utilization.

[0054] Next, the structures of the lower mold main mold frame 1, the upper mold main mold frame 2, the lower mold partition mold 3 and the upper mold partition mold 4 are introduced:

[0055] Lower mold main mold frame 1

[0056] like Figure 2 As shown, the lower mold main mold frame 1 has multiple Figure 2 The first partition installation areas 11 are arranged in the A direction (in the middle) and the first limit blocks 12 are located at both ends of the plurality of first partition installation areas 11. The first partition installation areas 11 are used to install the lower mold partition mold 3.

[0057] Since the vehicle carpet has a rectangular structure as a whole, in order to save costs, the lower mold main mold frame 1 can have a rectangular structure, and the first direction can be the length direction of the rectangular structure. In this way, multiple lower mold partition molds 3 installed along the first direction can form the shape of the vehicle carpet.

[0058] The lower mold main mold frame 1 has two first limit blocks 12 , which are located at two ends of the lower mold main mold frame 1 along the first direction and on both sides of the plurality of continuous first partition installation areas 11 .

[0059] A first partition limiting strip 13 is located between every two adjacent first partition mounting areas 11. The first partition limiting strip 13 extends perpendicular to the first direction. When the lower mold partition mold 3 is mounted on the lower mold main mold frame 1, every two adjacent first partition limiting strips 13 limit the lower mold partition mold 3 in the first direction. The first partition limiting strips 13 located at both ends, together with the first limiting blocks 12, limit the lower mold partition mold 3 mounted at the ends of the lower mold main mold frame 1 in the first direction.

[0060] The second direction of each first partition installation area 11 (such as Figure 2One end on the B direction) has a first end limiting strip 14, wherein the second direction is perpendicular to the first direction, and the second direction can also be called the extension direction of the first partition limiting strip 13.

[0061] It can be seen that the first partition installation area 11 has a rectangular structure, and its three sides respectively have two first partition limit bars 13 and a first end limit bar 14, or, the three sides respectively have a first partition limit bar 13, a first end limit bar 14 and a first limit block 12 to limit the lower mold partition mold 3 installed in the first partition installation area 11 in three directions.

[0062] When installing the lower mold partition mold 3, the lower mold partition mold 3 can be inserted into the first partition installation area 11 from the side where the first partition limit bar 13, the first end limit bar 14 and the first limit block 12 are not set. After it is inserted into the first partition installation area 11, it is connected to the lower mold main mold frame 1.

[0063] Upper mold main mold frame 2

[0064] like Figure 3 As shown, the upper mold main mold frame 2 has multiple Figure 3 The second partitioned mounting areas 21 are arranged in the direction A of the upper mold base 4 and the second limit blocks 22 are located at both ends of the second partitioned mounting areas 21. The second partitioned mounting areas 21 are used to mount the upper mold base 4. The position of each second partitioned mounting area 21 corresponds to the position of a different first partitioned mounting area 11. In this way, when the lower mold base 1 and the upper mold base 2 are closed, each second partitioned mounting area 21 is arranged opposite a first partitioned mounting area 11.

[0065] Likewise, the upper mold main mold frame 2 may have a rectangular parallelepiped structure, and the first direction may be the length direction of the rectangular parallelepiped structure. In this way, a plurality of upper mold partition molds 4 installed along the first direction may form the shape of a vehicle carpet.

[0066] The upper mold frame 2 has two second stoppers 22 located at either end of the upper mold frame 2 along the first direction and on either side of a plurality of consecutive second partitioned mounting areas 21. The position of each second stopper 22 corresponds to the position of a different first stopper 12. Thus, when the lower mold frame 1 and the upper mold frame 2 are joined, each second stopper 22 is positioned opposite a first stopper 12.

[0067] A second partition limiting strip 23 is located between each two adjacent second partition mounting areas 21. The second partition limiting strip 23 extends perpendicular to the first direction. When the upper mold partition mold 4 is mounted on the upper mold main mold frame 2, each two adjacent second partition limiting strips 23 limit the upper mold partition mold 4 in the first direction. The second partition limiting strips 23 located at both ends, together with the second limiting blocks 22, limit the upper mold partition mold 4 mounted at the ends of the upper mold main mold frame 2 in the first direction.

[0068] The second direction of each second partition installation area 21 (such as Figure 3 One end in the B direction) has a second end limiting strip 24, wherein the second direction can also be referred to as the extension direction of the second partition limiting strip 23.

[0069] The second partition installation area 21 has a rectangular structure, and its three sides respectively have two second partition limit bars 23 and a second end limit bar 24, or, the three sides respectively have a second partition limit bar 23, a second end limit bar 24 and a second limit block 22 to limit the upper mold partition mold 4 installed in the second partition installation area 21 in three directions.

[0070] When installing the upper mold partition mold 4, the upper mold partition mold 4 can be inserted into the second partition installation area 21 from the side where the second partition limit bar 23, the second end limit bar 24 and the second limit block 22 are not set. After it is inserted into the second partition installation area 21, it is connected to the upper mold main mold frame 2.

[0071] Lower mold partition mold 3

[0072] like Figure 4 As shown, each lower mold partition mold 3 is located in a different first partition installation area 11 and is connected to the lower mold main mold frame 1. The sides of the lower mold partition mold 3 are in contact with the first partition limit strips 13 or the first limit blocks 12 on both sides of the corresponding first partition installation area 11, and are in contact with the first end limit strip 14 at one end of the corresponding first partition installation area 11.

[0073] When installing the lower mold partition mold 3, for the lower mold partition mold 3 that needs to be installed in the first partition installation area 11 located between the two first partition limit bars 13, the lower mold partition mold 3 is inserted into the first partition installation area 11 from the side where the first partition limit bar 13 and the first end limit bar 14 are not set, and the two first partition limit bars 13 and the first end limit bar 14 located on the three sides of the lower mold partition mold 3 are in contact with the lower mold partition mold 3, thereby limiting it and limiting it in the first partition installation area 11, and then, the lower mold partition mold 3 is fixedly connected to the lower mold main mold frame 1, thereby realizing the connection between the lower mold partition mold 3 and the lower mold main mold frame 1.

[0074] For the lower mold partition mold 3 that needs to be installed in the first partition installation area 11 between a first partition limit bar 13 and a first limit block 12, the lower mold partition mold 3 is inserted into the first partition installation area 11 from the side where the first partition limit bar 13, the first limit block 12 and the first end limit bar 14 are not set, and the first partition limit bar 13, the first limit block 12 and the first end limit bar 14 located on the three sides of the lower mold partition mold 3 are in contact with the lower mold partition mold 3, thereby limiting it and limiting it in the first partition installation area 11, and then, the lower mold partition mold 3 is fixedly connected to the lower mold main mold frame 1, thereby realizing the fixed connection of the lower mold partition mold 3 located at the end of the lower mold main mold frame 1.

[0075] like Figure 5 As shown, Figure 5 It is a structural schematic diagram of multiple lower mold partition molds 3 installed on the lower mold main mold frame 1.

[0076] Upper mold partition mold 4

[0077] like Figure 6 As shown ( Figure 6 Only one upper mold partition mold 4 is shown. Figure 6 The upper mold partition mold 4 and Figure 4 The lower mold partition molds 3 in the figure are not corresponding to each other), each upper mold partition mold 4 is located in a different second partition installation area 21, and is connected to the upper mold main mold frame 2, and the side portions of the upper mold partition mold 4 are in contact with the second partition limit strips 23 or the second limit blocks 22 on both sides of the corresponding second partition installation area 21, and are in contact with the second end limit strip 24 at one end of the corresponding second partition installation area 21.

[0078] When installing the upper mold partition mold 4, for the upper mold partition mold 4 that needs to be installed in the second partition installation area 21 located between the two second partition limit bars 23, the upper mold partition mold 4 is inserted into the second partition installation area 21 from the side where the second partition limit bar 23 and the second end limit bar 24 are not set, and the two second partition limit bars 23 and the second end limit bar 24 located on the three sides of the upper mold partition mold 4 are in contact with the upper mold partition mold 4, thereby limiting it and limiting it in the second partition installation area 21, and then, the upper mold partition mold 4 is fixedly connected to the upper mold main mold frame 2, thereby realizing the connection between the upper mold partition mold 4 and the upper mold main mold frame 2.

[0079] For the upper mold partition mold 4 that needs to be installed in the second partition installation area 21 located between a second partition limit bar 23 and a second limit block 22, the upper mold partition mold 4 is inserted into the second partition installation area 21 from the side where the second partition limit bar 23, the second limit block 22 and the second end limit bar 24 are not set, and the second partition limit bar 23, the second limit block 22 and the second end limit bar 24 located on the three sides of the upper mold partition mold 4 are in contact with the upper mold partition mold 4, thereby limiting it and limiting it in the second partition installation area 21. Then, the upper mold partition mold 4 is fixedly connected to the upper mold main mold frame 2, thereby realizing the fixed connection of the upper mold partition mold 4 located at the end of the upper mold main mold frame 2.

[0080] Partition mold

[0081] When the lower mold main mold frame 1 and the upper mold main mold frame 2 are closed, each lower mold partition mold 3 is connected to the corresponding upper mold partition mold 4, and each upper mold partition mold 4 is respectively combined with the corresponding lower mold partition mold 3 to form a partition mold, such as Figure 7 As shown, every two adjacent partition molds are interconnected, so that a plurality of continuous partition molds can form a molding cavity of the entire vehicle carpet for foam molding of the vehicle carpet.

[0082] In a possible implementation, the structure in which adjacent partition molds are interconnected may be: Figure 8 As shown, there is a gap 5 between the lower mold partition mold 3 and the corresponding upper mold partition mold 4, that is, the side of the partition mold composed of the lower mold partition mold 3 and the corresponding upper mold partition mold 4 has a gap 5, and the positions of the gaps 5 of each two adjacent partition molds correspond to each other, which is used for mutual communication between the two adjacent partition molds.

[0083] It can be understood that after multiple lower mold partition molds 3 are installed on the lower mold main mold frame 1, the sides of two adjacent lower mold partition molds 3 in these multiple lower mold partition molds 3 are in contact, thereby forming a lower part of the cavity that matches the shape of the product. Similarly, after multiple upper mold partition molds 4 are installed on the upper mold main mold frame 2, the sides of two adjacent upper mold partition molds 4 in these multiple upper mold partition molds 4 are in contact, thereby forming an upper part of the cavity that matches the shape of the product. After the lower mold main mold frame 1, the lower mold partition mold 3, the upper mold main mold frame 2 and the upper mold partition mold 4 are closed, the sides of adjacent partition molds are in contact and are only connected through the notches 5 set opposite to each other.

[0084] There are many ways to connect the lower mold partition mold 3 and the lower mold main mold frame 1. Correspondingly, there are also many ways to connect the upper mold partition mold 4 and the upper mold main mold frame 2. The following is an introduction using one of them as an example:

[0085] The connection method between the lower mold partition mold 3 and the lower mold main mold frame 1: the side of the lower mold main mold frame 1 close to the lower mold partition mold 3 has multiple first threaded holes, and the lower mold partition mold 3 has multiple first through holes. The position of each first through hole corresponds to the position of a different first threaded hole, and the lower mold main mold frame 1 and the lower mold partition mold 3 are threadedly connected by bolts, first threaded holes and first through holes.

[0086] When installing the lower mold partition mold 3, after the lower mold partition mold 3 is inserted into the corresponding first partition installation area 11, the lower mold partition mold 3 is limited by the first partition limit bar 13, the first end limit bar 14 and the first limit block 12. The multiple first through holes on the lower mold partition mold 3 are all aligned with the multiple first threaded holes on the lower mold main mold frame 1. At this time, the bolts can be screwed into the first through holes and the first threaded holes to fix the lower mold partition mold 3 and the lower mold main mold frame 1.

[0087] The connection method between the upper mold partition mold 4 and the upper mold main mold frame 2: the side of the upper mold main mold frame 2 close to the upper mold partition mold 4 has multiple second threaded holes, and the upper mold partition mold 4 has multiple second through holes. The position of each second through hole corresponds to the position of a different second threaded hole, and the upper mold main mold frame 2 and the upper mold partition mold 4 are threadedly connected by bolts, second threaded holes and second through holes.

[0088] When installing the upper mold partition mold 4, after the upper mold partition mold 4 is inserted into the corresponding second partition installation area 21, the upper mold partition mold 4 is limited by the second partition limit bar 23, the second end limit bar 24 and the second limit block 22. The multiple second through holes on the upper mold partition mold 4 are all aligned with the multiple second threaded holes on the upper mold main mold frame 2. At this time, the bolts can be screwed into the second through holes and the second threaded holes to fix the upper mold partition mold 4 and the upper mold main mold frame 2 in connection.

[0089] In a possible implementation, the lower mold main mold frame 1 further has a structure that can improve the convenience of inserting the lower mold partition mold 3 into the first partition installation area 11. The structure can be as follows:

[0090] The lower mold main mold frame 1 includes a lower mold main mold frame body, a first lifting device, a first guide plate and a plurality of first balls.

[0091] For each first partition mounting area 11, the side surface of the lower mold main mold frame corresponding to the first partition mounting area 11 has a first groove and multiple first threaded holes. The side surface of the lower mold main mold frame corresponding to the first partition mounting area 11 is the surface of the lower mold main mold frame where the first partition mounting area is located. The first threaded holes are provided on this side surface. After the lower mold partition mold 3 is inserted into the first partition mounting area 11, the lower mold partition mold 3 contacts this side surface and is fixedly connected to it via bolts.

[0092] The first lifting device is located in the first groove and is connected to the lower mold main mold frame body. The first side of the first guide plate is connected to the lifting platform of the first lifting device. Multiple first balls are distributed along the length direction of the first guide plate and are connected to the second side of the first guide plate. The first lifting device can rise to the point where the first ball is higher than the side of the lower mold main mold frame body corresponding to the first partition installation area 11, or can descend to the point where the first ball is lower than the side of the lower mold main mold frame body corresponding to the first partition installation area 11.

[0093] Among them, the length direction of the first guide plate is the extension direction of the first partition limit strip 13, and the first ball can roll in any direction, but since the first ball is fixedly connected to the first guide plate, the first ball can rotate around its own center of the ball and cannot move in position relative to the first guide plate.

[0094] Before installing the lower mold partition mold 3, the first lifting device, the first guide plate and the first ball are all located in the first groove, that is, the first ball is lower than the side of the lower mold main mold frame body corresponding to the first partition installation area 11. When preparing to install the lower mold partition mold 3, it is necessary to first control the first lifting device to rise until the first ball is higher than the side of the lower mold main mold frame body corresponding to the first partition installation area 11. Then, the lower mold partition mold 3 can be inserted into the first partition installation area 11. Since the length direction of the first guide plate, the arrangement direction of the multiple first balls and the extension direction of the first partition limit bar 13 are the same, during the insertion process, with the limitation of the first partition limit bar 13 or the first limit block 12, the lower mold partition mold 3 can slide along the arrangement direction of the multiple first balls. The first ball can improve the convenience of inserting the lower mold partition mold 3 into the first partition installation area 11.

[0095] After the lower mold partition mold 3 is inserted into the first partition installation area 11, the first lifting device can be controlled to descend until the first ball is lower than the side of the lower mold main mold frame body corresponding to the first partition installation area 11. At this time, due to the existence of the first ball, there is a gap between the lower mold partition mold 3 and the lower mold main mold frame body. At this time, a bolt is inserted into the first through hole and the first threaded hole and tightened to make the lower mold partition mold 3 contact with the lower mold main mold frame body, eliminate the gap, and fix the lower mold partition mold 3 to the lower mold main mold frame body.

[0096] It can be understood that for each first partition installation area 11, a group of structures consisting of a first lifting device, a first guide plate and multiple first balls can be set up, or, for each first partition installation area 11, two groups of the above structures can be set along the first direction to further improve convenience.

[0097] Similarly, the upper mold main mold frame 2 can also have the same structure as above to improve the convenience of inserting the upper mold partition mold 4 into the second partition installation area 21. Its structure is as follows:

[0098] The upper mold main mold frame 2 includes an upper mold main mold frame body, a second lifting device, a second guide plate and a plurality of second balls.

[0099] For each second partition installation area 21, the side of the upper mold main mold frame body corresponding to the second partition installation area 21 has a second groove and multiple second threaded holes, the second lifting device is located in the second groove and is connected to the upper mold main mold frame body, the third side of the second guide plate is connected to the lifting platform of the second lifting device, and multiple second balls are distributed along the length direction of the second guide plate and are connected to the fourth side of the second guide plate. The second lifting device can rise to the point where the second ball is higher than the side of the upper mold main mold frame body corresponding to the second partition installation area 21, or can descend to the point where the second ball is lower than the side of the upper mold main mold frame body corresponding to the second partition installation area 21.

[0100] Among them, the length direction of the second guide plate is the extension direction of the second partition limit strip 23, and the second ball can roll in any direction, but since the second ball is fixedly connected to the second guide plate, the second ball can rotate around its own center and cannot move in position relative to the second guide plate.

[0101] Before installing the upper mold partition mold 4, the second lifting device, the second guide plate and the second ball are all located in the first groove, that is, the second ball is lower than the side of the upper mold main mold frame body corresponding to the second partition installation area 21. When preparing to install the upper mold partition mold 4, it is necessary to first control the second lifting device to rise until the second ball is higher than the side of the upper mold main mold frame body corresponding to the second partition installation area 21. Then, the upper mold partition mold 4 can be inserted into the second partition installation area 21. Since the length direction of the second guide plate, the arrangement direction of the multiple second balls and the extension direction of the second partition limit bar 23 are the same, during the insertion process, with the limitation of the second partition limit bar 23 or the second limit block 22, the upper mold partition mold 4 can slide along the arrangement direction of the multiple first balls, and the second ball can improve the convenience of inserting the upper mold partition mold 4 into the second partition installation area 21.

[0102] After the upper mold partition mold 4 is inserted into the second partition installation area 21, the second lifting device can be controlled to descend until the second ball is lower than the side of the upper mold main mold frame body corresponding to the second partition installation area 21. At this time, due to the presence of the second ball, there is a gap between the upper mold partition mold 4 and the upper mold main mold frame body. At this time, a bolt is inserted into the second through hole and the second threaded hole and tightened to make the upper mold partition mold 4 contact with the upper mold main mold frame body, eliminate the gap, and fix the upper mold partition mold 4 to the upper mold main mold frame body.

[0103] It can be understood that for each second partition installation area 21, a group of structures consisting of a second lifting device, a second guide plate and multiple second balls can be set up, or, for each second partition installation area 21, two groups of the above structures can be set along the first direction to further improve convenience.

[0104] In a possible implementation, the structure that can improve the convenience of inserting the lower mold partition mold 3 into the first partition installation area 11 can also be:

[0105] The width of the first partition limiting strip 13 gradually increases along the extension direction of the first partition limiting strip 13 and toward the first end limiting strip 14 , wherein the width of the first partition limiting strip 13 is the length of the first partition limiting strip 13 in the first direction.

[0106] Based on the above structure, during the process of inserting the lower mold partition mold 3 into the first partition installation area 11, that is, during the process of inserting the lower mold partition mold 3 between two adjacent first partition limit bars 13, or during the process of inserting the lower mold partition mold 3 between the first partition limit bar 13 and the first limit block 12, since the width of the first partition limit bar 13 at a position away from the first end limit bar 14 is smaller, the distance between the two adjacent first partition limit bars 13 (or the distance between the first partition limit bar 13 and the first limit block 12) is greater than the width of the lower mold partition mold 3, making it easier to insert the lower mold partition mold 3 into the first partition installation area 11, and as the lower mold partition mold 3 is inserted, the insertion of the first partition limit bar 13 can gradually tighten and limit the lower mold partition mold 3. The above structure can improve the convenience of inserting the lower mold partition mold 3 into the first partition installation area 11.

[0107] Furthermore, in order to enhance the limiting stability of the first partition limit strip 13 on the lower mold partition mold 3, the first partition limit strip 13 can also have multiple limiting protrusions on the side close to the lower mold partition mold 3. The limiting protrusions of two adjacent first partition limit strips 13 are opposite, and the limiting protrusions on both sides are opposite to each other to limit the lower mold partition mold 3.

[0108] Similarly, the side of the first limiting block 12 close to the lower mold partition mold 3 may also have a limiting protrusion. The limiting protrusion on the first limiting block 12 and the limiting protrusion on the first partition limiting strip 13 together limit the lower mold partition mold 3 between the two.

[0109] Similarly, the structure for improving the convenience of inserting the upper mold partition mold 4 into the second partition installation area 21 can be the same as the above structure, which is:

[0110] The width of the second partition limiting strip 23 gradually increases along the extension direction of the second partition limiting strip 23 and toward the second end limiting strip 24 , wherein the width of the second partition limiting strip 23 is the length of the second partition limiting strip 23 in the first direction.

[0111] Based on the above structure, during the process of inserting the upper mold partition mold 4 into the second partition installation area 21, that is, during the process of inserting the upper mold partition mold 4 between two adjacent second partition limit bars 23, or during the process of inserting the upper mold partition mold 4 between the second partition limit bar 23 and the second limit block 22, since the width of the second partition limit bar 23 at a position away from the second end limit bar 24 is smaller, the distance between the two adjacent second partition limit bars 23 (or the distance between the second partition limit bar 23 and the second limit block 22) is greater than the width of the upper mold partition mold 4, making it easier for the upper mold partition mold 4 to be inserted into the second partition installation area 21, and as the upper mold partition mold 4 is inserted, the insertion of the second partition limit bar 23 can gradually tighten and limit the upper mold partition mold 4. The above structure can improve the convenience of the upper mold partition mold 4 in the process of inserting the second partition installation area 21.

[0112] Furthermore, in order to enhance the limiting stability of the second partition limit strip 23 on the upper mold partition mold 4, the second partition limit strip 23 can also have multiple limiting protrusions on the side close to the upper mold partition mold 4. The limiting protrusions of two adjacent second partition limit strips 23 are opposite, and the limiting protrusions on both sides are opposite to each other to limit the upper mold partition mold 4.

[0113] Similarly, the side of the second limiting block 22 close to the upper mold partition mold 4 may also have a limiting protrusion. The limiting protrusion on the second limiting block 22 and the limiting protrusion on the second partition limiting strip 23 together limit the upper mold partition mold 4 between the two.

[0114] After installing multiple lower mold partition molds 3 on the lower mold main mold frame 1 and multiple upper mold partition molds 4 on the upper mold main mold frame 2, it is necessary to close the lower mold main mold frame 1 and the upper mold main mold frame 2. That is, the lower mold main mold frame 1 is placed flat on the ground, and the upper mold main mold frame 2 is buckled onto the lower mold main mold frame 1. During the closing process of the lower mold main mold frame 1 and the upper mold main mold frame 2, in order to enhance the accuracy of the position between the two, the following settings can also be made:

[0115] like Figure 2 and Figure 3 As shown, the side of the first limiting block 12 close to the second limiting block 22 has a limiting column 121 , and the side of the second limiting block 22 close to the first limiting block 12 has a limiting groove 221 , and the limiting column 121 is located in the limiting groove 221 .

[0116] After the lower mold main mold frame 1 and the upper mold main mold frame 2 are closed, the position of the first limit block 12 is opposite to the position of the second limit block 22, and the limit column 121 on the first limit block 12 is inserted into the limit groove 221 of the second limit block 22. The shape of the limit column 121 can match the shape of the limit groove 221, so that the limit column 121 is just inserted into the limit groove 221, and the side of the first limit block 12 can contact the side of the second limit block 22, further supporting the upper mold main mold frame 2 after closing the mold and enhancing the overall strength.

[0117] In a possible implementation, in order to further improve the support of the upper mold main mold frame 2 after mold closing, the following settings can also be made:

[0118] like Figure 2 、 Figure 3 and Figure 9 As shown, the position of each first partition limit strip 13 corresponds to the position of a different second partition limit strip 23, and both ends of the side of the first partition limit strip 13 close to the second partition limit strip 23 have a first reinforcement column 15, that is, the two first reinforcement columns 15 are located on the two ends of the first partition limit strip 13 along the second direction, and both ends of the side of the second partition limit strip 23 close to the first partition limit strip 13 have a second reinforcement column 25, and these two second reinforcement columns 25 are located on the two ends of the second partition limit strip 23 along the second direction, and the position of each first reinforcement column 15 corresponds to the position of a different second reinforcement column 25, and the first reinforcement column 15 is in contact with the second reinforcement column 25.

[0119] That is, after the lower mold main mold frame 1 and the upper mold main mold frame 2 are closed, the first reinforcement column 15 on the lower mold main mold frame 1 contacts the second reinforcement column 25 on the upper mold main mold frame 2, further supporting the upper mold main mold frame 2 and enhancing the overall strength.

[0120] In one possible implementation, since the brake vehicle carpet requires foaming of the foamed adhesive in multiple partitioned molds, and the foamed adhesive needs to be heated during the foaming process, the partitioned molds may also be configured as follows:

[0121] The lower partition mold 3 has a first heat conduction circuit at its end near the lower main mold frame 1, and the upper partition mold 4 has a second heat conduction circuit at its end near the upper main mold frame 2. It is understood that the first heat conduction circuit is embedded within the lower partition mold 3, and the second heat conduction circuit is also embedded within the upper main mold frame 2.

[0122] The first hot water conducting circuit and the second hot water conducting circuit both have a water inlet and a water outlet. Before the foaming glue is filled into the bottom of the lower partition mold 3, hot water is continuously supplied to the water inlets of the first hot water conducting circuit and the second hot water conducting circuit. The hot water heats the foaming glue in the cavity of the partition mold during the process of passing through the first hot water conducting circuit and the second hot water conducting circuit, thereby promoting the foaming of the foaming glue.

[0123] In one possible implementation, since the vehicle carpet consists of a two-layer structure, with the upper layer being a decorative layer and the lower layer being a foam layer, workers need to first use another mold to form the decorative layer. When making the foam layer, the decorative layer needs to be placed at the bottom of the upper partition mold 4, and the foam glue needs to be filled at the bottom of the lower partition mold 3. In this way, after the molds are closed, the foam glue in the lower partition mold 3 foams and expands upward, exerting upward pressure on the decorative layer, causing it to fit into the bottom of the upper partition mold 4. During the mold closing process, since the upper partition mold 4 needs to be inverted on the lower partition mold 3, a certain structure is required to fix the decorative layer at the bottom of the upper partition mold 4. This structure can be:

[0124] like Figure 9 As shown, the upper partition mold 4 has an exhaust hole 41 on its side near the upper main mold frame 2. The upper partition mold 4 also has multiple exhaust holes on its side near one end of the upper main mold frame 2. That is, after the upper main mold frame 2 is inverted onto the lower main mold frame 1, the exhaust hole 41 is located on the side, and the multiple exhaust holes are located on the top. The exhaust holes are relatively small in diameter.

[0125] Before closing the mold, a vacuum pump can be used to connect the multiple exhaust holes 41 on the upper mold partition mold 4. After the decorative layer is placed on the upper mold partition mold 4, the vacuum pump can be started to vacuum the air between the decorative layer and the bottom of the upper mold partition mold 4. During this process, the vacuuming speed is greater than the speed of air flowing into the exhaust holes. The decorative layer will gradually adhere to the bottom of the upper mold partition mold 4 until the decorative layer blocks the exhaust holes at the bottom of the upper mold partition mold 4, completing the vacuuming operation. The staff can close the upper mold partition mold 4 and the lower mold partition mold 3 during the vacuuming process, or they can close them after vacuuming. The operation can be performed according to the actual situation.

[0126] In a possible implementation, the lower mold main mold frame 1 and the upper mold main mold frame 2 may also have multiple weight-reducing holes to save costs and reduce weight.

[0127] The mold provided in the embodiment of the present application can be any one of the above structures, or a combination of any multiple of the above structures, and can be set according to actual needs. The embodiment of the present application does not limit this.

[0128] The technical solutions provided by the embodiments of the present application include at least the following beneficial effects:

[0129] The embodiment of the present application provides a mold platform for foam molding, which includes a lower mold main mold frame 1, an upper mold main mold frame 2, a plurality of lower mold partition molds 3 and a plurality of upper mold partition molds 4. The lower mold main mold frame 1 has a plurality of first partition installation areas 11 arranged along a first direction, and the upper mold main mold frame 2 has a plurality of second partition installation areas 21 arranged along the first direction. Each lower mold partition mold 3 is respectively located in a different first partition installation area 11 and is connected to the lower mold main mold frame 1. Each upper mold partition mold 4 is respectively located in a different second partition installation area 21 and is connected to the upper mold main mold frame 2. Each upper mold partition mold 4 forms a partition mold with the corresponding lower mold partition mold 3, and every two adjacent partition molds are connected to each other. By using the mold in this application, when there are local differences in the vehicle carpets of two different models, it is only necessary to replace the lower mold partition mold 3 and the upper mold partition mold 4 corresponding to the layout difference, without the need to redevelop and replace the mold of the entire vehicle carpet. In this way, the production efficiency of the vehicle carpet is improved and the cost is reduced. At the same time, the storage space for the molds of vehicle carpets of different models is reduced, thereby improving resource utilization.

[0130] The present application also provides a method for foaming a vehicle carpet, which is applied to any of the above-mentioned mold platforms for foaming, such as Figure 10 As shown, the method includes:

[0131] 101. Each lower mold partition mold 3 is set in the corresponding first partition installation area 11 and connected to the lower mold main mold frame 1. Each upper mold partition mold 4 is set in the corresponding second partition installation area 21 and connected to the upper mold main mold frame 2.

[0132] During implementation, corresponding multiple lower mold partition molds 3 and corresponding multiple upper mold partition molds 4 can be selected according to the vehicle model. Then, each lower mold partition mold 3 is installed in the first partition installation area 11 corresponding to the lower mold main mold frame 1 in the order of arrangement, and the lower mold partition mold 3 is connected to the lower mold main mold frame 1. According to the corresponding order, each upper mold partition mold 4 is installed in the second partition installation area 21 corresponding to the upper mold main mold frame 2, and the upper mold partition mold 4 is connected to the upper mold main mold frame 2.

[0133] 102. Use foam glue to fill the bottoms of multiple lower mold partition molds 3, and set the molded decorative layer of the vehicle carpet on the bottoms of multiple upper mold partition molds 4.

[0134] In practice, the decorative layer of the vehicle carpet of the vehicle model can be placed at the bottom of the multiple upper partition molds 4, and then a vacuum pump can be used to evacuate the upper partition molds 4 so that the decorative layer is always at the bottom of the upper partition mold 4. Then, foam glue can be used to fill the bottom of the multiple lower partition molds 3.

[0135] 103. Clamp the upper mold main mold frame 2 and the lower mold main mold frame 1, and use a hydraulic press to fix the upper mold main mold frame 2 and the lower mold main mold frame 1 after the mold is clamped.

[0136] During implementation, the upper mold main mold frame 2 and the lower mold main mold frame 1 are clamped, and then a hydraulic press is used to apply pressure to the clamped upper mold main mold frame 2 and the lower mold main mold frame 1, so that the upper mold main mold frame 2 and the lower mold main mold frame 1 will not be lifted up by the foam, maintaining the connection and sealing between the two.

[0137] 104. Wait for the foaming glue to foam and form, thereby obtaining a foaming layer connected to the decorative layer, and the decorative layer and the foaming layer constitute a vehicle carpet.

[0138] During implementation, after waiting for a period of time, the foamed rubber is foamed and formed, it fills the cavities of multiple partitioned molds and is connected with the decorative layer. Then, the mold is opened to obtain a vehicle carpet composed of the decorative layer and the foamed layer.

[0140] In this application, the terms "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. It should be understood that there is no logical or temporal dependency between "first" and "second," nor does it limit the quantity or order of execution.
