AI Technical Summary
In the current leather case assembly process, the lower half of the leather layer is easily affected by external forces during placement, causing the position to shift. This results in the foam being misaligned in the space formed by the upper and lower half of the leather layer, which in turn affects the quality of the leather case forming.
The mold is fixed by a leather sleeve. The lower and upper leather layers are fixed by the first and second leather layer fixing pillars and the foam contour forming area to prevent them from shifting. The mold is stably closed by the top plate fixing pillar to ensure the accurate positioning of the foam during the hot pressing operation.
It effectively prevents the foam from misaligning between the leather layers, reduces the defect rate in leather case production, and improves molding quality.

Abstract
Description
Technical Field
[0001] This disclosure relates to the field of leather case manufacturing technology, and in particular to a leather case fixing mold and a leather case manufacturing device. Background Technology
[0002] Currently, leather covers on the market can be used in car seats, keyboard armrests, medical hand pads, elbow protection, and other scenarios. Their function is to reduce the burden on the user's arms / wrist / elbow and prevent fatigue.
[0003] In the current leather case assembly process, the lower half of the leather is placed at the bottom, then foam is placed on the lower half of the leather, and finally the upper half of the leather is placed on the foam, with the edge of the upper half of the leather overlapping the edge of the lower half of the leather to form the leather case to be pressed, and then a heat pressing operation is performed.
[0004] However, when placing the lower half of the leather layer, the lack of a fixed device makes it susceptible to external forces when placed on a horizontal surface, causing it to shift in position. This hinders the subsequent sequential placement of the foam and upper half of the leather layer, resulting in misalignment of the foam within the space formed by the lower and upper half of the leather layer. Consequently, after hot pressing and cooling to form the leather sleeve, the foam's outline within the upper and lower half of the leather layer becomes misaligned, leading to an increased defect rate in the finished leather sleeve. Utility Model Content
[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a sleeve fixing mold and sleeve production device that will not cause misalignment of the lower half of the skin or foam, and that will not cause misalignment of the contours formed by the foam in the upper half of the skin and the lower half of the skin after the sleeve is formed.
[0006] The purpose of this disclosure is achieved through the following technical solution:
[0007] A leather case fixing mold for assisting in the assembly of leather cases includes a mounting base plate, a lower leather layer, foam, an upper leather layer, and a mounting top plate. The mounting base plate has a first leather layer fixing post and a top plate fixing post, and also has a first foam contour forming area. The lower leather layer has a first clearance hole, through which the first leather layer fixing post passes. The lower leather layer has a foam mounting area, which corresponds to the foam clearance area. The foam is mounted on the lower leather layer, and the foam... The bottom is corresponding to the foam installation area; the upper half of the skin layer is installed on the foam, and the upper half of the skin layer has a second clearance hole; the mounting top plate is provided with a second skin layer fixing post, and the mounting top plate has a fixing clearance hole and a second foam contour forming area. The second skin layer fixing post passes through the second clearance hole, and the top of the foam is corresponding to the second foam contour forming area. The top plate fixing post passes through the fixing clearance hole so that the edge of the upper half of the skin layer coincides with the edge of the lower half of the skin layer.
[0008] In one embodiment, the mounting base plate is interconnected with a base plate body and an auxiliary mounting plate. The top plate fixing post is disposed on the base plate body, the first skin fixing post is disposed on the auxiliary mounting plate, the first foam contour forming area is located in the auxiliary mounting plate, the auxiliary mounting plate has a fixing through hole, and the top plate fixing post passes through the fixing through hole so that the auxiliary mounting plate is mounted on the base plate body.
[0009] In one embodiment, the first skin fixation post is positioned facing the second skin fixation post.
[0010] In one embodiment, the number of the first skin fixation posts is multiple.
[0011] In one embodiment, the number of the first clearance holes is multiple.
[0012] In one embodiment, a plurality of the first skin fixing posts are inserted through the corresponding first clearance holes.
[0013] In one embodiment, the number of the second skin fixation posts is multiple.
[0014] In one embodiment, the number of the second clearance holes is multiple.
[0015] In one embodiment, a plurality of second skin fixing posts are inserted through corresponding second clearance holes.
[0016] In one embodiment, the cross-sectional area of the first foam contour forming region is equal to the cross-sectional area of the second foam contour forming region.
[0017] In one embodiment, the height of the foam ranges from 18mm to 20mm.
[0018] A leather case production apparatus includes a leather case fixing mold as described in any of the above embodiments.
[0019] Compared with the prior art, this disclosure has at least the following advantages:
[0020] When assembling the leather case, the lower half of the leather layer, the foam, and the upper half of the leather layer are stacked sequentially. The first leather layer fixing post passes through the first clearance hole to fix the lower half of the leather layer and prevent it from shifting. The lower half of the leather layer has a foam installation area, which facilitates the corresponding placement of the foam in the foam installation area. If the lower half of the leather layer does not shift, the foam will not shift either. The second leather layer fixing post passes through the second clearance hole to fix the upper half of the leather layer and prevent it from shifting. After stable placement, the top plate fixing post passes through the fixing clearance hole to make the mounting base plate and the mounting top plate cover each other. This facilitates subsequent hot pressing and cooling shaping. At this time, the outline formed by the foam in the upper and lower half of the leather layer will not be misaligned, thereby effectively reducing the defect rate of leather case production.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0030] Please see Figure 1 and Figure 2 This is a leather case fixing mold 10 according to an embodiment of the present utility model, used to assist in assembling leather cases, including a mounting base plate 100, a lower half leather layer 200, foam 300, an upper half leather layer 400, and a mounting top plate 500.
[0031] The mounting base plate 100 is provided with a first skin fixing post 101 and a top plate fixing post 102. The mounting base plate 100 also has a first foam contour forming area 103. The lower half skin 200 has a first clearance hole 201, and the first skin fixing post 101 passes through the first clearance hole 201 to fix the lower half skin 200. The lower half skin 200 has a foam mounting area 202, which is correspondingly set with the first foam contour forming area 103. The foam 300 is installed on the lower half skin 200, and the bottom of the foam 300 is correspondingly set with the foam mounting area 202. The upper half skin 400 is installed on the foam 300. The top plate 500 is provided with a second clearance hole 401; the top plate 500 is provided with a second skin fixing post 510, the top plate 500 is provided with a fixing clearance hole 501 and a second foam contour forming area 502, the second skin fixing post 510 passes through the second clearance hole 401 to fix the upper half skin 400, the top plate fixing post 102 passes through the fixing clearance hole 501, the top of the foam 300 is correspondingly set with the second foam contour forming area 502 so that the edge of the upper half skin 400 coincides with the edge of the lower half skin 200, and it is also convenient to heat press the edge of the upper half skin 400 and the edge of the lower half skin 200 together during the subsequent hot pressing operation. The first foam contour forming area 103 is used to form a bottom contour on the lower half skin layer 200 of the bottom surface of the foam 300 during the subsequent hot pressing operation, and the second foam contour forming area 502 is used to form a top contour on the upper half skin layer 400 of the top surface of the foam 300 during the subsequent hot pressing operation.
[0032] In this embodiment, when assembling the leather case, that is, when the lower half leather layer 200, foam 300 and upper half leather layer 400 are stacked in sequence, the first leather layer fixing post 101 passes through the first clearance hole 201 to fix the lower half leather layer 200 and prevent the lower half leather layer 200 from shifting. The lower half leather layer 200 has a foam mounting area 202, which facilitates the corresponding placement of foam 300 in the foam mounting area 202. If the lower half leather layer 200 does not shift, the foam 300 will also not shift. The second leather fixing post 510 passes through the second clearance hole 401 to fix the upper half leather 400 and prevent the upper half leather 400 from shifting. After it is stably placed, the top plate fixing post 102 passes through the fixing clearance hole 501 to make the mounting base plate 100 cover the mounting top plate 500. This facilitates the subsequent hot pressing operation and cooling and shaping. At this time, the outline of the foam 300 formed by the upper half leather 400 and the lower half leather 200 will not be misaligned, thereby effectively reducing the defect rate of the leather case production.
[0033] In another embodiment, the upper skin layer 400 is made of polyurethane, the lower skin layer 200 is made of polyurethane, and the foam 300 is made of polyethylene or polyurethane.
[0034] like Figure 3As shown, in one embodiment, the mounting base 100 includes a base body 110 and an auxiliary mounting plate 120 connected to each other. A top plate fixing post 102 is disposed on the base body 110, a first skin layer fixing post 101 is disposed on the auxiliary mounting plate 120, a first foam contour forming area 103 is located within the auxiliary mounting plate 120, and the auxiliary mounting plate 120 has a fixing through hole 121. The top plate fixing post 102 passes through the fixing through hole 121 to allow the auxiliary mounting plate 120 to be mounted on the base body 110. It can be understood that the top plate fixing post 102 passes through the fixing through hole 121 to allow the auxiliary mounting plate 120 to be mounted on the mounting base 100. The top plate fixing post 102 is used to fix the auxiliary mounting plate 120, preventing the auxiliary mounting plate 120 from shifting position and facilitating the fixing of the lower skin layer 200 to the auxiliary mounting plate 120.
[0035] like Figure 2 As shown, in one embodiment, the first skin fixing post 101 is positioned facing the second skin fixing post 510. It can be understood that, to facilitate the upper skin layer 400 facing the lower skin layer 200, so that the edges of the upper skin layer 400 and the lower skin layer 200 overlap when the mounting top plate 500 and the mounting bottom plate 100 are closed, the first skin fixing post 101 faces the second skin fixing post 510. Thus, the upper skin layer 400 faces downwards towards the lower skin layer 200. Since the second skin fixing post 510 passes through the second clearance hole 401, the upper skin layer 400 is secured to the mounting top plate 500, making it less likely for the upper skin layer 400 to slip off under its own force.
[0036] In one embodiment, there are multiple first skin layer fixing posts 101; and / or multiple first clearance holes 201. In this embodiment, there are multiple first skin layer fixing posts 101 and multiple first clearance holes 201, and the number is equal. Further, multiple first skin layer fixing posts 101 are inserted through corresponding first clearance holes 201. When multiple first skin layer fixing posts 101 are inserted through corresponding first clearance holes 201, they can jointly fix the lower half of the skin layer 200, further preventing the lower half of the skin layer 200 from detaching from the mounting base plate 100 or even deviating from its position.
[0037] In one embodiment, there are multiple second skin layer fixing posts 510; and / or, there are multiple second clearance holes 401. In this embodiment, there are multiple second skin layer fixing posts 510 and multiple second clearance holes, and the number is equal. Further, multiple second skin layer fixing posts 510 are inserted through corresponding second clearance holes 401. When multiple second skin layer fixing posts 510 are inserted through corresponding second clearance holes 401, they can jointly fix the upper skin layer 400, further preventing the upper skin layer 400 from detaching from the mounting top plate 500 or even deviating from its position.
[0038] In one embodiment, the cross-sectional area of the first foam contour forming area 103 is equal to the cross-sectional area of the second foam contour forming area 502. It can be understood that during the subsequent hot-pressing operation of the casing, since both the upper half of the casing 400 and the lower half of the casing 200 are softened, the foam 300 forms a bottom contour on the lower half of the casing 200 and a top contour on the upper half of the casing 400. When the cross-sectional area of the first foam contour forming area 103 is equal to the cross-sectional area of the second foam contour forming area 502, the cross-sectional area of the bottom contour is equal to the cross-sectional area of the top contour. This results in a casing with better overall integrity, making it less likely for the cross-sectional areas of the upper and lower parts of the casing to be inconsistent.
[0039] In one embodiment, the height of foam 300 ranges from 18mm to 20mm. In this embodiment, the height of foam 300 is 20mm.
[0040] This disclosure also provides a leather case production apparatus, including any of the leather case fixing molds 10 described in the above embodiments.
[0041] Compared with the prior art, this disclosure has at least the following advantages:
[0042] When assembling the leather case, that is, when the lower half leather layer 200, foam 300 and upper half leather layer 400 are stacked in sequence, the first leather layer fixing post 101 passes through the first clearance hole 201 to fix the lower half leather layer 200 and prevent the lower half leather layer 200 from shifting. The lower half leather layer 200 has a foam mounting area 202, which facilitates the corresponding placement of foam 300 in the foam mounting area 202. If the lower half leather layer 200 does not shift, the foam 300 will also not shift. The second leather layer... The fixing post 510 passes through the second clearance hole 401 to fix the upper half of the leather layer 400 and prevent the upper half of the leather layer 400 from shifting. After it is stably placed, the fixing post 102 passes through the fixing clearance hole 501 to make the mounting base plate 100 cover the mounting top plate 500. This facilitates the subsequent hot pressing operation and cooling and shaping. At this time, the outline of the foam 300 formed by the upper half of the leather layer 400 and the lower half of the leather layer 200 will not be misaligned, thereby effectively reducing the defect rate of the leather case production.
[0043] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
