Description

Technical Field

[0001] The utility model belongs to the technical field of automobile interior decoration manufacturing, in particular to an auxiliary positioning device for pouring edge lines of interior decoration. Background Art

[0002] In the field of polyurethane foam manufacturing for automotive interiors, the clarity of the edges of the slush-molded skin and its matching degree with the surrounding parts are crucial to the quality of the product appearance, and they are both affected by the positioning of the slush-molded skin and the casting mold.

[0003] The existing vacuum adsorption method for positioning the plastic skin has some limitations. Affected by the vacuum pump power, skin edge sealing, skin thickness, skin hardness, product structure, etc., the positioning effect is difficult to be accurate and unstable. For some complex surface shapes, the products produced often have unclear edges and do not match the environment.

[0004] The edges of some products have changed from right angles to three folds. The small edge in the middle is easily misaligned with the cast insert when laying the skin. The small edge inwards causes the step difference to become smaller, and the small edge outwards causes the gap to become larger. The current solution is to polish the cast insert and improve the skin laying method, but this measure is not stable enough and the product appearance quality fluctuates.

[0005] As described in CN201721092595.3 “A skin laying device for instrument panel foaming mold”, a manipulator is used to grab the slush molding profiling block, and the movement of the manipulator and the telescopic cylinder are used to “press” the slush molding skin onto the surface of the casting mold, and the vacuum adsorption force of the casting mold is used to adsorb the slush molding skin. However, this technology is theoretically contradictory, because the skin grain surface of the slush molding skin is firstly close to the slush molding mold. When it is laid on the casting mold, the skin grain surface needs to be separated from the slush molding mold first, and then it can be adsorbed onto the surface of the casting mold. According to the practice of this utility model, the slush molding mold and the casting mold will interfere with each other. Utility Model Content

[0006] In view of the above problems, the utility model provides an auxiliary positioning device for interior decoration casting edges, including a base, a large forceps, a first profiling block, a second profiling block, a guide column, a hand-wrench clamp and a connecting rod; the center lever of the large forceps is fixed on the base, and the ends of the large forceps are respectively fixed on the two first profiling blocks. When the large forceps move, the two first profiling blocks can be moved closer or farther away, the two second profiling blocks and the two first profiling blocks are arranged in parallel, the second profiling block is fixed with a guide column, the first profiling block is sleeved outside the guide column and slidably cooperates with the guide column, and the first A hand-lever clamp is fixed on the profiling block, and the hand-lever clamp is connected to the second profiling block through a connecting rod. The hand-lever clamp can drive the second profiling block to make the guide column reciprocate on the first profiling block. The utility model has high positioning accuracy and a profiling clamping design, which can accurately fit the slush molded skin on the casting mold. The adjustment is flexible, and the clamping force and clamping stroke can be quantitatively adjusted to adapt to the changes in hardness and thickness of different batches of slush molded skins, thereby improving the applicability and flexibility of the device, realizing complex modeling, and allowing the foamed product to have more complex and varied edge shapes.

[0025] An auxiliary positioning device for casting edges of interior decoration comprises a base 1, a strong pliers 7, a first profiling block 2, a second profiling block 3, a guide column 4, a hand clamp 5, a connecting rod 6 and a guide sleeve 8.

[0026] A second profiling block 3 is provided on the base 1, a guide column 4 is fixed on the second profiling block 3, the first profiling block 2 is sleeved outside the guide column 4 and slidably cooperates with the guide column 4, a hand clamp 5 is fixed on the first profiling block 2, the hand clamp 5 is connected to the second profiling block 3 through a connecting rod 6, and the hand clamp 5 can drive the second profiling block 3 to reciprocate on the guide column 4.

[0027] A guide sleeve 8 is disposed outside the guide column 4 .

[0028] The ends of the powerful pliers 7 are fixed on the two first contour blocks 2 respectively.

[0029] There are two second contour blocks 3 which are arranged in parallel on the base 1 .

[0030] The distance between the two second contour blocks 3 is 1-10 cm.

[0031] The powerful pliers 7 and the hand clamp 5 can be driven by a cylinder or a motor to realize automatic production.

[0032] Working order:

[0033] Lay the skin 10 on the casting insert 9;

[0034] Putting the auxiliary device on the epidermis 10;

[0035] Manually clamp the strong forceps 7 to make the first profiling block 2 fit tightly against the upper surface and the side surface of the epidermis 10 and clamp them;

[0036] The inner and outer hand-pull clamps 5 are respectively pulled to move the second contour block 3 downward, so that the lower part of the skin 10 is closely fitted with the lower part of the insert 9 and clamped.

[0037] See Figure 4 When the hand-operated clamp 5 moves, it can move axially relative to the base.

[0038] The segmented and sequential contour clamping design can accurately fit the slush skin onto the casting mold according to the drawing requirements. The device can quantitatively adjust the clamping force and clamping stroke to adapt to the changes in hardness and thickness of different batches of slush skin, so that the foamed product can have more complex and varied ridge shapes.

[0039] First, use a pair of strong pliers to clamp the upper contour block onto the plastic surface so that it fits closely with the upper and side surfaces of the cast insert and is clamped tightly.

[0040] Then use the hand clamp to clamp the lower profiling block in the specified direction, so that the visible ridge area of ​​the skin is accurately and firmly attached to the casting mold. Specifically, if the skin ridge needs to be turned outward, the lower profiling block is clamped from top to bottom, and if the skin needs to be turned inward, the lower profiling block is clamped from bottom to top. The clamping force and clamping stroke can be quantitatively adjusted by adjusting the mechanical limit.
