Description

Technical Field

[0001] The utility model belongs to the technical field of manufacturing real wood decorative pieces, and relates to a tool for injection molding and placing real wood veneer inlays. Background Art

[0002] Real wood trim is widely used in the interiors of aircraft, ships, and vehicles. It's formed by applying veneer through a series of processes, including lamination, hot pressing, injection molding, milling, and spraying. As a key process in veneer molding, injection molding's production stability and efficiency directly impact the efficiency and quality of real wood trim.

[0003] In the existing technology, veneer is manually picked up and installed in the cavity of the injection molding machine. After the veneer is injection-molded, it is manually removed from the cavity of the injection molding machine. This process requires workers to frequently move the veneer in and out of the injection molding machine, which not only leads to low veneer injection molding efficiency, but also poses a safety hazard to workers entering and exiting the injection molding machine.

[0004] Therefore, the utility model addresses the defects of the prior art in which manual handling of veneers is labor-intensive, inefficient, and has potential safety hazards, and discloses a tool for injection molding and placing real wood veneer inserts. Utility Model Content

[0005] The purpose of the utility model is to provide a real wood veneer insert injection molding placement tool, which only requires workers to hang and position the veneer outside the injection molding machine. Subsequently, the veneer is moved to the injection molding machine cavity, the veneer is hung and positioned, and the veneer is taken out, which is automatically and efficiently performed by the placement tool, thereby improving the processing efficiency of the veneer injection molding, avoiding the need for workers to enter and exit the injection molding machine, and ensuring the safety of the workers.

[0006] The utility model is achieved through the following technical solutions:

[0008] A human operator, positioned outside the injection molding machine, hangs the veneer onto the positioning pins to achieve precise positioning. A robotic arm then moves the veneer, aligning the positioning holes in the veneer with the cavity positioning pins inside the injection molding machine. The positioning pins and a push mechanism then move axially relative to each other, pushing the veneer onto the cavity positioning pins inside the injection molding machine. This ensures the veneer adheres closely to the cavity surface, allowing the veneer to be injection molded. Once the veneer is injection-molded, the robotic arm drives the second side of the mounting frame to align with the veneer. A pickup mechanism on the gripping frame then removes the molded veneer from the injection molding machine and places it in the desired location.

[0009] In order to better implement the present invention, further, a rotating cylinder is provided on the second side of the mounting frame, and the rotating end of the rotating cylinder is connected to one side of the clamping frame.

One end of the clamping frame is connected to the rotating end of the rotating cylinder, and two groups of pneumatic clamps are arranged at the other end of the clamping frame. A pneumatic suction cup is arranged between the two ends of the clamping frame.

[0011] In order to better implement the present invention, further, the top, middle and bottom of the first side of the mounting frame are symmetrically provided with hanging pin mounting plates, and positioning hanging pins are installed on the hanging pin mounting plates.

[0012] In order to better realize the present utility model, further, the pushing device is fixedly arranged on the hanging needle mounting plate, and the positioning hanging needle moves axially relative to the pushing device; the positioning hanging needle includes a hanging needle body and a telescopic cylinder, and the hanging needle mounting plate is provided with a telescopic cylinder, the telescopic end of the telescopic cylinder passes through the hanging needle mounting plate and is connected to one end of the hanging needle body, and the hanging needle body is arranged through a through hole on the pushing device.

[0030] Example 1:

[0031] A real wood veneer insert injection molding placement tooling of this embodiment, such as Figure 1-Figure 3As shown, it includes a robotic arm 1 and a mounting frame 2 connected to the robotic arm 1. A plurality of positioning hanging pins 3 are provided on the first side of the mounting frame 2, and a pushing device 4 is provided around the positioning hanging pins 3. The positioning hanging pins 3 and the pushing device 4 can move axially relative to each other; a clamping frame 5 is rotatably provided on the second side of the mounting frame 2 opposite to the first side, and a picking device 6 is provided on the side of the clamping frame 5 away from the mounting frame 2.

[0032] The robotic arm 1 is connected to one side of the mounting frame 2 via a connecting flange, and the robotic arm 1 drives the mounting frame 2 to move in three axes in space. The mounting frame 2 is made of aluminum profiles, ensuring sufficient rigidity while reducing its weight. Several positioning pins 3 are provided on the first side of the mounting frame 2, corresponding to the positioning holes in the veneer. The positioning pins 3 are made of stainless steel and are less than or equal to 150 mm long. The ends of the positioning pins 3 are chamfered with a taper of 1:50-1:30 to ensure that the positioning holes can be more smoothly attached to the positioning pins 3 when the veneer is attached. A pushing device 4 is provided around the positioning pins 3. The pushing device 4 and the positioning pins 3 are able to move relative to each other along the axial direction of the positioning pins 3. The pushing device 4 pushes the veneer attached to the positioning pins 3 into the cavity of the injection molding machine, so that the positioning holes in the veneer are attached to the cavity positioning pins inside the injection molding machine cavity. A gripping frame 5 is rotatably mounted on a second side of the mounting frame 2, relative to the first side. Made of aluminum, this frame 5 maintains sufficient rigidity while reducing its weight. Furthermore, the gripping frame 5 can be rotated relative to the mounting frame 2 to adjust the position of a pickup device 6 thereon. This device 6 is used to remove molded veneer from the mold cavity of the injection molding machine, allowing operators to load and remove molded veneer from outside the mold cavity.

[0033] Furthermore, the mounting frame 2 and the clamping frame 5 are both provided with weight-reducing holes. By providing the weight-reducing holes, the weight of the mounting frame 2 and the clamping frame 5 can be further reduced, thereby reducing the energy consumption of the veneer injection molding and transportation process.

[0034] Example 2:

[0035] A real wood veneer insert injection molding placement tooling, improved on the basis of Example 1, such as Figure 3 As shown, a rotary cylinder 7 is provided on the second side of the mounting frame 2, and the rotating end of the rotary cylinder 7 is connected to one side of the gripping frame 5. The rotation of the rotary cylinder 7 drives the gripping frame 5 to rotate relative to the mounting frame 2 to adjust the gripping position of the gripping device 6, ensuring that the gripping device 6 can stably and smoothly pick up and remove the veneer that has been injection-molded in the cavity of the injection molding machine.

[0036] Furthermore, the picking device 6 includes a pneumatic suction cup 61 and a pneumatic clamp 62. One end of the clamping frame 5 is connected to the rotating end of the rotating cylinder 7. Two groups of pneumatic clamps 62 are arranged at the other end of the clamping frame 5. A pneumatic suction cup 61 is provided between the two ends of the clamping frame 5. The pneumatic suction cup 61 is provided corresponding to the adsorption end surface on the veneer, and the veneer that has been injection molded is directly adsorbed and picked up by the pneumatic suction cup 61. At the same time, in order to ensure the stability of the veneer transportation and removal process, a pneumatic clamp 62 is provided on the clamping frame 5 at a position corresponding to the clamping groove on the veneer. The pneumatic clamp 62 clamps and fixes the clamping groove, further preventing the veneer from falling during the removal process from the injection molding machine cavity.

[0037] The rest of this embodiment is the same as that of embodiment 1, so it will not be described again.

[0038] Example 3:

[0039] A real wood veneer insert injection molding placement tooling, improved on the basis of embodiment 1 or 2, such as Figure 2 As shown, pin mounting plates 8 are symmetrically arranged at the top, middle, and bottom of the first side of the mounting frame 2. Positioning pins 3 are mounted on the pin mounting plates 8. One end of the pin mounting plate 8 is connected to the corresponding threaded hole on the mounting frame 2 via a connecting bolt, and the other end of the pin mounting plate 8 is used to mount the positioning pin 3.

[0040] The rest of this embodiment is the same as that of embodiment 1 or 2, and thus will not be described in detail.

[0041] Example 4:

[0042] A real wood veneer insert injection molding placement tooling, improved on the basis of any one of embodiments 1-3, such as Figure 4 As shown, the pushing device 4 is fixedly set on the hanging needle mounting plate 8, and the positioning hanging needle 3 moves axially relative to the pushing device 4; the positioning hanging needle 3 includes a hanging needle body 31 and a telescopic cylinder 32, and the hanging needle mounting plate 8 is provided with a telescopic cylinder 32. The telescopic end of the telescopic cylinder 32 passes through the hanging needle mounting plate 8 and is connected to one end of the hanging needle body 31, and the hanging needle body 31 is set through the through hole on the pushing device 4.

[0043] As described in this embodiment, the pushing device 4 is fixed and the positioning hanging pin 3 is movably installed, so that the positioning hanging pin 3 can move axially relative to the pushing device 4. The telescopic cylinder 32 is originally in an extended state. At this time, the end of the hanging pin body 31 extends to the outside of the through hole on the pushing device 4, and the staff can hang the veneer on the end of the hanging pin body 31. The veneer is moved to the inside of the cavity of the injection molding machine by the robotic arm 1, and the positioning hole on the veneer is aligned with the cavity positioning pin inside the cavity of the injection molding machine. At this time, the telescopic cylinder 32 retracts, and then drives the hanging pin body 31 to retract. During the retraction of the hanging pin body 31, the pushing device 4 pushes the veneer toward the cavity positioning pin, so that the veneer is hung on the cavity positioning pin. At the same time, the reverse pushing force of the pushing device 4 presses the veneer against the cavity surface.

[0044] Furthermore, the through hole and the positioning hanging pin 3 are connected with a clearance fit, that is, a gap is left between the positioning hanging pin 3 and the through hole, ensuring that the hanging pin body 31 can be smoothly extended and retracted.

[0045] The rest of this embodiment is the same as any one of Embodiments 1-3, so it will not be described again.

[0046] Example 5:

[0047] A real wood veneer insert injection molding placement tooling, improved on the basis of any one of embodiments 1-4, such as Figure 5 As shown, the positioning hanging needle 3 is fixedly mounted on the hanging needle mounting plate 8, and the pushing device 4 moves axially relative to the positioning hanging needle 3; the pushing device 4 includes a pushing plate 41 and a pushing cylinder 42, and the pushing plate 41 is provided with a through hole for the positioning hanging needle 3 to pass through, and one side of the pushing plate 41 is connected to the hanging needle mounting plate 8 through the pushing cylinder 42.

[0048] As described in this embodiment, the positioning pin 3 is fixed and the positioning device 4 is movably installed, so that the positioning device 4 can move axially relative to the positioning pin 3. The push cylinder 42 is originally in a retracted state, so that the end of the positioning pin 3 can extend out of the through hole on the push plate 41. At this time, the staff can hang the positioning hole on the veneer on the end of the positioning pin 3. The veneer is moved to the inside of the cavity of the injection molding machine by the robotic arm 1, and the positioning hole on the veneer is aligned with the cavity positioning pin inside the cavity of the injection molding machine. At this time, the push cylinder 42 is extended, and then the push plate 41 is driven to push the veneer toward the cavity positioning pin, so that the veneer moves to the inside of the cavity and is hung on the cavity positioning pin, and the veneer is fit to the cavity surface.

[0049] Furthermore, the through hole and the positioning hanging pin 3 are connected with a clearance fit, that is, a gap is left between the positioning hanging pin 3 and the through hole, ensuring that the positioning hanging pin 3 can be smoothly extended and retracted.

[0050] The rest of this embodiment is the same as any one of Embodiments 1-4, and therefore will not be described in detail.

[0051] Example 6:

[0052] A real wood veneer insert injection molding placement tooling, improved on the basis of any one of embodiments 1-5, such as Figure 6 As shown, the positioning hanging needle 3 and the pushing device 4 are both movably installed on the hanging needle mounting plate 8, and the positioning hanging needle 3 and the pushing device 4 can move axially relative to each other; the positioning hanging needle 3 includes a hanging needle body 31 and a telescopic cylinder 32, and the pushing device 4 includes a pushing plate 41 and a pushing cylinder 42; the hanging needle mounting plate 8 is provided with a telescopic cylinder 32, and the telescopic end of the telescopic cylinder 32 passes through the hanging needle mounting plate 8 and is connected to one end of the hanging needle body 31; the pushing plate 41 is provided with a through hole for the hanging needle body 31 to pass through, and one side of the pushing plate 41 is connected to the hanging needle mounting plate 8 through the pushing cylinder 42.

[0053] The telescopic cylinder 32 is initially extended, while the push cylinder 42 is initially retracted, allowing the end of the pin body 31 to extend outside the through-hole on the push plate 41. This allows the operator to attach the veneer's positioning holes to the end of the pin body 31. The robotic arm 1 drives the veneer into the cavity of the injection molding machine, aligning the veneer's positioning holes with the cavity positioning pins inside the cavity. The telescopic cylinder 32 then retracts while the push cylinder 42 extends, allowing the push plate 41 to push the veneer into the cavity of the injection molding machine, attaching the veneer's positioning holes to the cavity positioning pins and ensuring the veneer adheres closely to the cavity surface.

[0054] Furthermore, the through hole and the positioning hanging pin 3 are connected with a clearance fit, that is, a gap is left between the positioning hanging pin 3 and the through hole, ensuring that the positioning hanging pin 3 can be smoothly extended and retracted.

[0055] The rest of this embodiment is the same as any one of Embodiments 1-5, so it will not be described again.

[0056] The above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention fall within the scope of protection of the present invention.
