Description

TECHNICAL FIELD

[0001] The present application relates to a kind of mould structure and production process using the mould structure, in particular to a kind of mould structure and automobile hatstand production process of automobile hatstand. BACKGROUND

[0002] Most of the automobile hatstand products are formed by bonding sheet material (such as honeycomb board, fiberboard and honeycomb fiber composite board, etc.) and decorative fabric (such as needle-punched fabric and other non-woven fabrics, etc.). The conventional manufacturing process is to punch the sheet material into shape by a skeleton mold, and the decorative fabric is cut according to the profile of the automobile hatstand product in the cutting die, and then the shaped skeleton and the cut decorative fabric are put into a composite mold to press into an integrated structure. Usually, glue is sprayed between the skeleton and the decorative fabric during the composite process of the skeleton and the decorative fabric. Since the skeleton is pressed to form a folded edge around the periphery, the folded edge around the periphery of the skeleton cannot be connected to the decorative fabric temporarily through automatic production, and the decorative fabric around the periphery needs to be adhered to the surface of the folded edge of the skeleton by semi-automatic or manual methods.

[0003] The automobile hatstand mold and manufacturing process described above have the following defects: 1. High production cost, three sets of molds (skeleton forming mold, decorative fabric cutting mold, and composite mold) are required to complete production, the equipment cost is high, the equipment occupies a large production area, one to two people are required to operate each mold, and the labor cost is high; 2. Low production efficiency, long product production cycle; 3. Due to the bending deformation of the skeleton during the forming process, the decorative fabric will not be able to wrap around the surface of the skeleton with 100% size correspondence or no error after being cut separately and then combined with the skeleton, and sometimes the decorative fabric will not be able to wrap around the surface of the skeleton accurately due to displacement or size error, which will affect the appearance of the automobile hatstand product and the quality of the product cannot be effectively guaranteed.

DETAILED DESCRIPTION

[0020] As Figures 1 to 4As shown, the mold structure of the hat and coat rack of the application comprises an upper mold 1 and a lower mold 6, and further comprises a middle mold 7. The middle mold 7 is located between the upper mold 1 and the lower mold 6. The upper mold 1 is connected to the four peripheries of the middle mold 7 through four limiting pull rods I 3 respectively, and the four peripheries of the middle mold 7 are connected to the four peripheries of the lower mold 6 through four positioning guide columns 5 respectively. The limiting pull rod II 18 is further connected to the inner side of the positioning guide column 5 between the middle mold 7 and the lower mold 6. The limiting pull rod I 3 can prevent the upper mold 1 from separating from the middle mold 7, the limiting pull rod II 18 can prevent the middle mold 7 from separating from the lower mold 6, and the positioning guide column 5 can ensure the accurate positional relationship between the middle mold 7 and the lower mold 6.

[0021] The upper mold 1 is fixedly connected to the bottom surface and is used for forming the hat and coat rack skeleton of the automobile. The profile of the convex mold 2 is the same as that of the hat and coat rack skeleton of the automobile. The upper end surface of the middle mold 7 is recessed downward and is provided with a positioning inclined surface 4 for positioning the hat and coat rack skeleton plate. The inner side of the positioning inclined surface 4 is provided with a through groove 8 penetrating the upper and lower surfaces of the middle mold 7. The profile of the through groove 8 is the same as the outer profile of the convex mold 2, and the position of the through groove 8 corresponds to the position of the convex mold 2 on the bottom surface of the upper mold 1. The bottom surface of the middle mold 7 is connected to a cutter mold 9 which can cut the outer peripheral profile of the decorative fabric. The cutter mold 9 is fixed to the bottom surface of the middle mold 7 through a fixing device. The profile of the cutter mold 9 is the same as the profile required to be finally cut on the decorative fabric. The outer edge of the cutter mold 9 on the bottom of the middle mold 7 is provided with a ring of middle mold peripheral recesses 10 recessed upward. The middle part of the upper surface of the lower mold 6 is recessed downward and is provided with a forming concave mold 11. The position of the forming concave mold 11 of the lower mold 6 corresponds to the position of the through groove 8 of the middle mold 7. The profile of the forming concave mold 11 of the lower mold 6 is the same as and corresponds to the profile of the convex mold 2 of the upper mold 1. The outer side peripheral edge of the forming concave mold 11 on the upper surface of the lower mold 6 is provided with a decorative fabric shaping surface 12. The profile of the decorative fabric shaping surface 12 is basically the same as the outer profile of the cutter mold 9 on the bottom surface of the middle mold 7 and the positions correspond to each other. When the cutter mold 9 cuts the decorative fabric downward on the bottom surface of the middle mold 7, the decorative fabric shaping surface 12 can support the decorative fabric to prevent the decorative fabric from wrinkling, so that the cutter mold 9 can quickly and accurately complete the cutting. The outer side peripheral edge of the decorative fabric shaping surface 12 on the upper surface of the lower mold 6 is further provided with a lower mold peripheral recess 13 which is lower than the horizontal position of the decorative fabric shaping surface 12. The position of the lower mold peripheral recess 13 corresponds to the position of the middle mold peripheral recess 10. The edge material cut by the cutter mold 9 will fall into the lower mold peripheral recess 13.

The plate material is positioned on the positioning inclined surface 4 of the middle mold 7, and the plate material needs to be baked in the baking device to make the surface soft before being placed in the middle mold 7. The decorative fabric is placed in the lower mold 6 and covers the decorative fabric shaping surface 12, and the decorative fabric is a needle-punched fabric. The upper mold 1, the middle mold 7 and the lower mold 6 are controlled to be closed, and the plate material is formed and simultaneously compounded with the decorative fabric to form an integrated hat and coat rack framework workpiece 14 during the forming process, and the peripheral edge cutting of the decorative fabric is completed during the compounding process (i.e. when the upper mold 1, the middle mold 7 and the lower mold 6 are closed), and the knife mold 9 at the bottom of the middle mold 7 cuts the peripheral edge of the decorative fabric in the lower mold 6 when the middle mold 7 goes down, to obtain the hat and coat rack framework workpiece 14 as shown in Figure 5 ; (2) after the mold is opened, the formed hat and coat rack framework workpiece 14 is taken out from the mold, and the hat and coat rack framework workpiece 14 is placed on the glue spraying workbench, the decorative fabric edge material 16 not connected to the framework fold 15 at the peripheral edge of the hat and coat rack framework workpiece 14 is sprayed with glue, and the decorative fabric with glue is adhered to the surface of the framework fold 15 at the peripheral edge of the hat and coat rack framework workpiece 14, to obtain the hat and coat rack product 17 as shown in Figure 6 .
