Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and in particular to a tool for embedding low-pressure injection molding fabrics and removing products from a B-pillar of an automobile. Background Art

[0002] With the development of the automobile industry, people have higher and higher requirements for automobile manufacturing technology. In order to improve the sensory level and comfort of automobile interior parts, more and more automobile interior parts use injection molding technology with hard plastic as the base material skeleton and fabric and soft plastic as the surface layer. The traditional process is to spray glue or adhesive on the surface of the product and then cover it with fabric; its disadvantages are many processes, long cycle and low production efficiency. The OEM has higher requirements for the air quality in the car, and the harmful substances volatilized by glue or adhesive seriously affect the air quality in the car.

[0003] Therefore, the low-pressure injection molding process is used instead. The low-pressure injection molding process requires the fabric (fabric or leather) to be placed in the mold in advance, and the product base material rubber is injected into the mold cavity with the help of the injection molding machine screw thrust. The stretch rate of the fabric is used to make one side of the fabric fit tightly with the product base material, and then the product is taken out after curing and molding. The low-pressure injection molding process requires the design of sharp and pointed hanging pins in the mold to position and fix the fabric. Manual workers need to use a ladder to enter the injection molding machine, pierce the fabric or fix it on the hanging pins in sequence through the pre-punched positioning holes. The above operation method has great safety risks, increases labor costs, and has low production efficiency. Summary of the invention

[0037] The specific working method is described below with specific embodiments:

[0038] Embodiment 1:

[0039] The automobile B-pillar low-pressure injection molding fabric embedding and product removal tooling of the present invention first drives the servo motor 1 41 in the reversing connection mechanism 4 through the small synchronous pulley 41-1, the synchronous belt, and the large synchronous pulley 42-1 to rotate the shell seat 42, the servo motor 2 43, the connecting flange 44, and the connecting plate 45 with the aluminum alloy frame 20 to rotate to the horizontal level. At this time, the embedding tooling 2-1 is grasped downward, and the manipulator moves the tooling assembly 2 to the top of the fabric, and makes the center hole of the pneumatic needle clamp 21-4 in the fabric grasping mechanism 21 coincide with the positioning hole on the fabric.

[0040] Then, the pneumatic needle clamp 21-4 works, the first needle clamp cylinder 21-40 drives the first needle 21-41 to extend and pierce the fabric, and the second needle clamp cylinder 21-42 drives the second needle 21-43 to extend and pierce the fabric, thereby achieving fabric positioning and clamping. At this time, the photoelectric sensor 23 arranged next to each pneumatic needle clamp 21-4 detects whether the fabric is clamped successfully.

[0041] After the fabric is successfully clamped, the manipulator moves the entire fabric clamping tooling assembly 2 to the middle of the static mold assembly 1 and the dynamic mold assembly 3, and positions it for the first time. At this time, the embedded tooling 2-1 is grasped toward the dynamic mold assembly 3, and the material picking tooling 2-2 is grasped toward the static mold assembly 1. Figure 1 shown.

[0042] Then, the first cylinder 21-1 extends, driving the pneumatic needle clamp 21-4 to extend, so that the pneumatic needle clamp 21-4 and the positioning hole on the fabric coincide with the hanging needle 30 on the movable mold assembly 3, and the left and right ends of the fabric move toward the middle by a specific distance. The extension stroke of the first cylinder 21-1 can be adjusted by the adjustable bracket 21-3.

[0043] Then, the embedding cylinder 22-1 in the fabric embedding mechanism 22 drives the pressing plate 22-3 to push out through the angle plate 22-2, so that the fabric is in a certain arc shape inward under the action of the pressing plate 22-3, so that the surface arc length of the fabric and the arc length of the outer surface of the product reach a certain ratio. The role of the fabric embedding mechanism 22 is particularly important in the low-pressure injection molding process: due to the limitation of the product structure and the excessive depth of the cavity section, if the fabric is directly embedded in the mold in a flat state during clamping, the fabric itself will have insufficient elongation after being fixed by the hanging needle 30 and under the pressure after the mold is closed. Under high-temperature molten rubber and injection pressure (low pressure below 50Bar), the fabric will have problems such as rupture, breakdown, glue overflow, color difference, wrinkles, and poor appearance texture.

[0044] Then, the manipulator moves the entire fabric clamping tooling assembly 2 toward the movable mold assembly 3, so that the positioning hole on the fabric passes through the hanging needle 30, and then the pneumatic needle clamp 21-4 works again, the first needle clamp cylinder 21-40 drives the first needle 21-41 to contract and loosen the fabric, and the second needle clamp cylinder 21-42 drives the second needle 21-43 to contract and loosen the fabric.

[0045] Then, the manipulator moves the entire tooling assembly 2 toward the static mold assembly 1 until the telescopic suction cup 24-3 in the suction mechanism 24 contacts and adsorbs the product. The adsorption position of the telescopic suction cup 24-3 can be adjusted by the adjustable bracket 24-1.

[0046] Then, the manipulator moves the entire product adsorption tooling assembly 2 toward the static mold assembly 1 for a stroke, and then the single-action finger 25-4 in the clamping mechanism 25 clamps the rock mouth edge of the product to ensure the reliability of product demoulding. The clamping position of the single-action finger 25-4 can be adjusted by the adjustable bracket 3 25-1, and the clamping angle can be adjusted by the connecting rod 25-2 and the connecting seat 25-3.

[0047] Then, the manipulator moves upward from between the static mold assembly 1 and the dynamic mold assembly 3 with the entire tooling assembly 2 for adsorbing and clamping the product, and completes the product removal.

[0048] The automobile B-pillar low-pressure injection molding fabric embedding and product removal tooling of the present invention is connected to the reversing connection mechanism 4 through a manipulator, so as to horizontally clamp the low-pressure injection molding fabric and embed it into the hanging needle 30 of the cavity of the movable mold component 3 for secondary positioning, and then take out the product. It is automated, eliminates manual operation, reduces the process of manually embedding fabrics, manually removing products, and manually starting and stopping the injection molding machine, avoids safety risks, reduces labor costs, and improves production efficiency.

[0049] Embodiment 2:

[0050] The low-pressure injection molding material embedding and product removal tooling for automobile B-pillars of the present invention has two sets of grabbing and embedding tooling 2-1 and two sets of material removal tooling 2-2, because the static mold assembly 1 and the dynamic mold assembly 3 simultaneously inject the left B-pillar and the right B-pillar of the automobile B-pillar. The number of grabbing and embedding tooling 2-1 and material removal tooling 2-2 can be expanded according to the product size, the size of the injection molding machine and the mold.

[0051] The automobile B-pillar low-pressure injection molding fabric embedding and product removal tooling of the present invention completes fabric embedding and product removal work once each time the entire tooling assembly 2 enters between the static mold assembly 1 and the dynamic mold assembly 3, thereby greatly improving production efficiency.

[0052] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above-mentioned concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
