Description

Technical Field

[0001] The invention relates to the technical field of hot pressing moulds, and in particular to a forming mould for producing underwear cups. Background Art

[0002] The characteristic of molded cup bras is that the cup can be thick or thin. It is formed in one step through the molding process. It has a certain shape and can achieve a good shaping effect. It does not require sewing. The cup part of molded cup bras is usually made of polyurethane soft foam or 3D vertical cotton. It is formed by high temperature and high pressure. Its appearance is round, natural, firm and full. According to the side profile of the bra, there are traditional types with uniform cup thickness and modern three-dimensional types with thick lower side and thin upper side. Among them, the three-dimensional cup has better correction and centralization effect.

[0003] Existing bra cups are usually made by hot pressing and deforming cup pieces with a mold. The cup pieces are manually placed on a lower mold, and the upper and lower molds move to press the cup pieces into the mold for hot pressing and shaping. On the one hand, manual placement of cup pieces may result in inaccurate positioning and high operating risks. On the other hand, each hot pressing requires first placing the material and then taking it out. The interval between the upper and lower molds is long, and heat loss is high, resulting in a longer preheating time, thereby greatly extending the interval time of hot pressing and affecting the processing speed of the cup. Therefore, a forming mold for the production of underwear cups is proposed. Summary of the invention

[0015] A molding process for producing underwear cups, comprising the following steps:

[0016] S1. Cutting pieces: first place the material plate on the die-cutting machine, and let the die-cutting machine cut out multiple groups of arc-shaped cutting holes on the material plate one by one, so that the arc-shaped cutting holes at the same place form the shape of the cutting piece, and cut out a specified number of positioning holes at the four corners of the material plate;

[0017] S2. Loading: Place the material sheet on top of the four right-angle lower clamps, align the positioning holes at the four corners of the material sheet with the positioning protrusions, insert the material sheet between the upper die and the lower die, and drive the clamping electric push rod to slide down and buckle the four corners of the material sheet to clamp the material sheet;

[0018] S3, hot pressing: multiple linear modules drive the transposition frame to move along two axes, so that the first group of cut pieces are located between the upper die and the lower die. At this time, the preheated upper die is driven by the driving end to close the mold with the lower die, and the internal group of cut pieces are hot pressed;

[0019] S4, transposition: After a period of hot pressing, the upper die and the lower die are separated, and the transposition frame drives the material plate to continue to move, so that the upper die and the lower die are subjected to the second round of hot pressing. The above operation is repeated until all the cut pieces on the material plate are hot pressed;

[0020] S5, blanking: the right-angle lower clamp and the right-angle upper clamp are separated from each other, the material plate is removed, and each formed piece is cut along the arc-shaped cutting hole to complete the forming process of this batch of cups.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention sets a plurality of linear modules, so that the upper and lower dies can complete the hot pressing of all the cut pieces on the material plate, thereby realizing batch and automatic hot pressing of the cups. Each movement of the material plate and loading of the cut pieces are automatically completed by the linear modules, which greatly shortens the loading time and effectively reduces the heat loss caused by each mold opening and loading, thereby shortening the preheating time before each hot pressing and improving the forming speed of the cups.

[0023] 2. The present invention provides arc-shaped cutting holes so that each cut piece is connected to the material plate only through a small amount of residual material after cutting the arc-shaped cutting holes, thereby reducing the pulling of the surrounding material plates when the cut pieces are deformed by hot pressing, so that the main deformation amount is concentrated inside each group of arc-shaped cutting holes. At the same time, when the material plate is moved, the visual recognition device on the driving end side can shoot and recognize the arc-shaped cutting holes on the adjacent side of the cut piece currently to be processed, so as to position the cut piece and effectively prevent the problem of misaligned forming;

[0024] 3. The present invention sets a clamping jaw assembly so that when loading a whole sheet of material, the sheet can be placed above the four right-angle lower clamping jaws, so that the sheet is inserted between the upper die and the lower die, so that the four corners of the sheet correspond to the four groups of right-angle lower clamping jaws and the right-angle upper clamping jaws respectively. At this time, the clamping electric push rod drives each right-angle upper clamping jaw to slide down and fasten on the top of the four corners of the sheet, so that the four groups of right-angle lower clamping jaws and the right-angle upper clamping jaws clamp the sheet and fix it. Otherwise, the sheet can be loosened, thereby realizing rapid loading and unloading of the sheet;

[0025] 4. The present invention sets a clamping jaw adjustment unit, so that when it is necessary to replace a material plate of different specifications, it is necessary to control the clamping jaw adjustment unit in advance to drive the four vertical cantilevers to move, thereby successively changing the positions of the four vertical cantilevers in the X-axis and Y-axis directions, and adjusting the clamping jaw assembly within a certain range, so that the four groups of right-angle lower clamping jaws and right-angle upper clamping jaws can adapt to the material plate of new specifications, so as to meet more molding requirements;

[0026] 5. The present invention sets an extended clamping jaw so that when the specification of the material plate increases, a specified number of extended clamping jaws can be placed at both ends of each right-angle lower clamping jaw and right-angle upper clamping jaw, respectively, so that the splicing plug rods on the extended clamping jaws are aligned with the splicing slots at various locations in turn for plugging, and then the two adjacent locking plates are locked together by the fastening bolt group, so that multiple extended clamping jaws are installed on both ends of each right-angle lower clamping jaw and right-angle upper clamping jaw in turn, increasing the clamping area of ​​the clamping jaw assembly on the four corners of the material plate, and vice versa, the number of extended clamping jaws can be reduced to reduce the clamping area, so that the force application range of the clamping jaw assembly can adapt to material plates of different specifications;

[0027] 6. The present invention provides positioning convex rods, so that when the material sheet is cut by the die-cutting machine, a specified number of positioning holes are cut out at the four corners of the material sheet. When the material sheet is loaded, the multiple positioning holes at one corner of the material sheet can be aligned with the positioning convex rods for sleeve connection, and the four corners of the material sheet can be pre-fixed by repeating the operation, so that the staff can stay away from the forming mold before the right-angle upper clamp descends, thereby reducing the occurrence of processing accidents;

[0028] 7. The present invention provides a heat dissipation U-shaped tube, so that during the process of hot pressing the cut pieces by the upper mold and the lower mold, the cooling water circulation system provided inside the hot press machine will circulate cooling water into each heat dissipation U-shaped tube, so that the heat dissipation U-shaped tube absorbs heat and cools the area around the group of cut pieces through the heat conduction frame, thereby avoiding excessive heating of the area around the cut pieces during the hot pressing process, which may cause deformation of other unformed or formed cut pieces and blank areas;

[0029] 8. The present invention provides a heat-conducting frame and a heat-conducting plate, so that the heat-conducting frame can absorb heat from the material plate area around the cut piece through each heat-conducting plate, so that the heat transferred through the material plate is transferred to the heat dissipation U-shaped tubes on both sides through the heat-conducting plate and the heat-conducting frame for conduction, reducing the four corners of the heat dissipation U-shaped tube, and making the heat dissipation of the heat-conducting frame more uniform;

[0030] 9. The present invention arranges a vacuum insulation sleeve so that the vacuum insulation sleeve located inside the heat-conducting frame and the lower mold is made of insulation material, and the interior is in a vacuum state or a state with low air content. This can effectively prevent the heat inside the upper mold and the lower mold from being lost due to outward transfer or absorption by the heat dissipation U-shaped tube, and at the same time prevent other areas of the material plate from being deformed by heat due to the transfer of heat from the upper mold and the lower mold to the outside.

In this embodiment, the two ends of the X-axis linear guide 5 are respectively provided with the second X-axis transposition slide 7 and the Y-axis linear guide 8, the two Y-axis linear guides 8 are located at the same end, the two second X-axis transposition slides 7 are located at the same end, and the two first X-axis transposition slides 6 and the two second X-axis transposition slides 7 are located at the same end. A Y-axis linear guide 8 is arranged on the top of the position slide 6, and a Y-axis linear guide 8 is also arranged on the top of the two second X-axis transposition slides 7. The top of the Y-axis linear guide 8 is driven to install a Y-axis transposition slide 9. The tops of the two Y-axis transposition slides 9 are fixedly installed with the same transposition frame 10. A hanging plate 11 is fixedly installed on the top of the transposition frame 10. A clamping claw assembly is arranged at the bottom of the hanging plate 11. A material plate 12 is arranged at the bottom of the clamping claw assembly. A visual recognition instrument 33 is fixedly installed on one side of the driving end 2, and the visual recognition instrument 33 faces the material plate 12.

[0049] like Figure 1 As shown, the material plate 12 is located between the upper mold 3 and the lower mold 4.

In this embodiment, the cooling water circulation system includes a cooling water tank, a water delivery pump, a shunt pipe, and a return pipe arranged inside the hot press 1. The water inlet end of the water delivery pump is connected to the cooling water tank of the lower mold 4, and the shunt pipe is connected to the output end of the water delivery pump, which is used to connect one end of the plurality of heat dissipation U-shaped tubes 29 and deliver cooling water to each heat dissipation U-shaped tube 29. The return pipe is directly connected to the cooling water tank and is used to connect the plurality of The other end of the heat dissipation U-shaped tube 29 draws cooling water from each heat dissipation U-shaped tube 29 for circulation under the action of the negative pressure of the water delivery pump; specifically, by setting the heat dissipation U-shaped tube 29, during the process of hot pressing the cut pieces 1201 by the upper mold 3 and the lower mold 4, the cooling water circulation system set inside the hot press machine 1 will circulate cooling water to the inside of each heat dissipation U-shaped tube 29, so that the heat dissipation U-shaped tube 29 can absorb heat and cool the area around the group of cut pieces 1201 through the heat conduction frame 28, thereby avoiding excessive heating of the area around the cut pieces 1201 during the hot pressing process, which may cause deformation of other unformed or formed cut pieces 1201 and blank areas.

[0055] like Figure 5 As shown, a plurality of evenly distributed heat-conducting frames 30 are fixedly installed inside the heat-conducting frame 28, and the heat-conducting frames 30 are respectively located between any two adjacent heat-dissipating U-shaped tubes 29. One end of the heat-conducting frame 30 extends to the outside of the heat-conducting frame 28 and is fixedly installed with a heat-conducting plate 31. Specifically, by arranging the heat-conducting frames 30 and the heat-conducting plates 31, the heat-conducting frames 30 can absorb heat from the material plate 12 area around the cut piece 1201 through each heat-conducting plate 31, so that the heat transferred through the material plate 12 will be transferred to the heat-dissipating U-shaped tubes 29 on both sides through the heat-conducting plates 31 and the heat-conducting frames 30 for conduction, thereby reducing the four corners of the heat-dissipating U-shaped tubes 29 from dissipating heat, and making the heat dissipation of the heat-conducting frame 28 more uniform.

[0056] like Figure 4 , Figure 5 As shown, vacuum insulation sleeves 32 are fixedly installed on the top of the hot press 1 and the bottom of the driving end 2. The two vacuum insulation sleeves 32 are respectively located between the upper mold 3 and the heat-conducting frame 28, and between the upper mold 3 and the heat-conducting frame 28. In the present embodiment, the vacuum insulation sleeves 32 are made of insulation material, and the interior of the vacuum insulation sleeves 32 is a hollow structure, and the interior is in a vacuum state or a state with less air content. Specifically, by setting the vacuum insulation sleeves 32, the vacuum insulation sleeves 32 located inside the heat-conducting frame 28 and the lower mold 4 are made of insulation material, and the interior is in a vacuum state or a state with less air content. This can effectively prevent the heat inside the upper mold 3 and the lower mold 4 from being lost due to outward transfer or absorption by the heat dissipation U-shaped tube 29, and at the same time prevent other areas of the material plate 12 from being heated and deformed due to the heat inside the upper mold 3 and the lower mold 4 being transferred to the outside.

[0057] like Fig.12 As shown, a molding process for producing underwear cups includes the following steps:

[0058] S1, cutting pieces: firstly, place the material plate 12 on the die-cutting machine, and make the die-cutting machine successively cut out multiple groups of arc-shaped cutting holes 1202 on the material plate 12, so that the arc-shaped cutting holes 1202 at the same position are surrounded by the shape of the cutting piece 1201, and cut out a specified number of positioning holes 1203 at the four corners of the material plate 12;

[0059] S2, loading: place the material sheet 12 on the four right-angle lower clamping jaws 19, align the positioning sockets 1203 at the four corners of the material sheet 12 with the positioning protruding rods 27 for sleeve connection, so that the material sheet 12 is inserted between the upper mold 3 and the lower mold 4, and the clamping electric push rod 21 drives each right-angle upper clamping jaw 20 to slide down and buckle on the top of the four corners of the material sheet 12 to clamp and fix the material sheet 12;

[0060] S3, hot pressing: multiple linear modules drive the transposition frame 10 to move along two axes, so that the first group of cut pieces 1201 is located between the upper mold 3 and the lower mold 4. At this time, the preheated upper mold 3 is driven by the driving end 2 to close the mold with the lower mold 4, and the group of cut pieces 1201 inside are hot pressed;

[0061] S4, transposition: After a period of hot pressing, the upper mold 3 and the lower mold 4 are separated, and the transposition frame 10 drives the material plate 12 to continue to move, so that the upper mold 3 and the lower mold 4 perform a second round of hot pressing, and the above operation is repeated until all the cut pieces 1201 on the material plate 12 are fully hot pressed;

[0062] S5, blanking: the right-angled lower clamping jaw 19 and the right-angled upper clamping jaw 20 are separated from each other, the blanking plate 20 is removed, and each formed cutting piece 1201 is cut along the arc-shaped cutting hole 1202 to complete the forming process of the batch of cups.

[0063] In summary: before forming: the staff first places the material plate 12 on the die-cutting machine, so that the die-cutting machine successively cuts out multiple groups of evenly distributed arc-shaped cutting holes 1202 on the material plate 12, so that the arc-shaped cutting holes 1202 at the same place are surrounded by the shape of the cutting piece 1201, and cuts out a specified number of positioning holes 1203 at the four corners of the material plate 12, and then places the material plate 12 above the four right-angle lower clamping jaws 19, aligns the multiple positioning holes 1203 at one corner of the material plate 12 with the positioning protruding rod 27 for sleeve connection, repeats the operation to pre-fix the four corners of the material plate 12, so that the material plate 12 is inserted between the upper mold 3 and the lower mold 4, so that the four corners of the material plate 12 correspond to the four groups of right-angle lower clamping jaws 19 and the right-angle upper clamping jaws 20 respectively, at this time The electric push rod 21 drives each right-angle upper clamp 20 to slide down and fasten on the top of the four corners of the material plate 12, so that the four groups of right-angle lower clamps 19 and the right-angle upper clamps 20 clamp the material plate 12 and fix it. Then the first X-axis transposition slide 6 and the second X-axis transposition slide 7 are driven synchronously to drive the two Y-axis linear guides 8 to move along the X-axis. The two Y-axis transposition slides 9 drive the transposition frame 10 to move along the Y-axis, thereby changing the position of the material plate 12 through the hanging plate 11 and the clamp assembly. The visual recognition device 33 on one side of the driving end 2 can shoot and identify the arc-shaped cutting hole 1202 on the adjacent side of the cut piece 1201 currently to be processed, and position the cut piece 1201 so that the first group of cut pieces 1201 are located between the upper mold 3 and the lower mold 4;

[0064] During forming: the preheated upper mold 3 is driven by the driving end 2 to close the mold with the lower mold 4, so as to perform hot pressing forming on a group of cut pieces 1201 inside. The cooling water circulation system arranged inside the hot press machine 1 will circulate cooling water into each heat dissipation U-shaped tube 29, so that the heat dissipation U-shaped tube 29 absorbs heat and cools the area around the group of cut pieces 1201 through the heat conduction frame 28. After a period of time, the driving end 2 is lifted to separate the upper mold 3 and the lower mold 4. The transposition frame 10 drives the material plate 12 to continue to move a unit distance through the clamping jaw assembly, so that the upper mold 3 and the lower mold 4 perform a second round of hot pressing forming, and the above operation is repeated until all the cut pieces 1201 on the material plate 12 are fully hot pressed;

[0065] After forming: the right-angled lower clamping jaw 19 and the right-angled upper clamping jaw 20 are separated from each other, the material plate 20 is removed, and each formed cutting piece 1201 is cut along the arc-shaped cutting hole 1202 to complete the forming process of the batch of cups.
