Description

A waste collection device for injection molding machines Technical Field

[0001] This application relates to the field of injection molding machine technology, and in particular to an injection molding machine waste collection device. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. Different parts require different molds. During the injection molding of special parts, waste material may remain in the mold after the molded part falls out.

[0003] Existing injection molding machines have a relatively simple structure. After removing the waste material remaining in the mold, it is usually thrown directly into the trash can, making it impossible to collect and reuse the waste material, which is a waste of resources.

[0004] Therefore, we propose an injection molding machine waste collection device to solve the above problems. Summary of the Invention

[0005] The purpose of this application is to provide a waste collection device for injection molding machines, which has the effect of collecting and utilizing waste.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an injection molding machine waste collection device, comprising an injection molding machine body, a base provided on the front of the injection molding machine body, a reducing pipe fixedly connected to the upper end of the base, a crushing box fixedly connected to the upper end of the reducing pipe, a receiving box fixedly connected to the upper end of the crushing box, a crushing mechanism provided inside the crushing box, a feeding pipe fixedly connected to the periphery of the reducing pipe, a collection bucket fixedly connected to the upper end of the material bucket of the injection molding machine body, the feeding pipe fixedly connected to the collection bucket, an exhaust fan installed on the upper end of the injection molding machine body, a connecting pipe fixedly connected to the output end of the exhaust fan, the connecting pipe fixedly connected to the collection bucket, and a solenoid valve installed at the bottom end of the collection bucket.

[0016] A further feature of this application is that a filter screen is fixedly connected to one end of the connecting pipe that is connected to the collecting bucket, and a bent pipe is fixedly connected to one end of the feeding pipe that is connected to the collecting bucket.

[0017] By adopting the above technical solution, it is possible to prevent debris from entering the connecting pipe and the exhaust fan. At the same time, the bend in the pipe facilitates the downward fall of debris that enters the collection bucket.

[0018] A further feature of this application is that a clamping mechanism is provided at the upper end of the injection molding machine body. The clamping mechanism includes a column, a second motor, and a positioning frame. The column is fixed to the upper end of the injection molding machine body by screws.

[0038] Specifically, the receiving box 5 is a box with a large opening at the top and a small opening at the bottom, and the bottom opening of the receiving box 5 is aligned with the middle of the two sets of rotating rods 61.

[0039] Specifically, the upper end of the reducing pipe 3 is a square reducing box, which can be easily connected to the bottom of the crushing box 4. The middle part is a conical reducing barrel, which can facilitate the accumulation of materials. The bottom end is a cylindrical barrel, and the bottom end of the cylindrical barrel is closed.

[0040] Specifically, the bottom of the crushing box 4 is supported by a support rod, which ensures the stability of the crushing box 4.

[0041] Specifically, a filter screen 12 is fixedly connected to one end of the connecting pipe 10 and the collecting bucket 8, and a bent pipe 13 is fixedly connected to one end of the feeding pipe 7 and the collecting bucket 8.

[0042] Specifically, the upper end of the injection molding machine body 1 is provided with a clamping mechanism 14.

[0046] With the above structure, the waste collection device for injection molding machines provided in this application removes the waste stuck on the mold and puts it into the collection box 5. The waste falls from the bottom of the collection box 5 into the crushing box 4. At this time, the first motor 64 drives the rotating rod 61 to rotate. The two sets of gears 63 can make the two sets of rotating rods 61 rotate at the same time. At this time, the blade 62 can cut the waste. The cut waste gathers downwards on the bottom surface of the inner diameter tube 3. At this time, the exhaust fan 9 can draw the broken material inside the diameter tube 3 into the collection bucket 8 through the feeding pipe 7. When the broken material is completely drawn out, the solenoid valve 11 can be opened to allow the broken material to enter the material bucket of the injection molding machine body 1.

[0047] The first telescopic cylinder 146 drives the slider 144 to slide along the guide rod 145, at which time the pneumatic finger 148 moves synchronously. The second telescopic cylinder 147 drives the pneumatic finger 148 to rise and fall, and the second motor 142 drives the positioning frame 143 to rotate. Moving the pneumatic finger 148 downward allows it to grip the waste material on the mold. After gripping the waste material, the pneumatic finger 148 is reset upward. At this time, the rotation of the positioning frame 143 allows the pneumatic finger 148 to move closer to the receiving box 5. When the pneumatic finger 148 rotates to the appropriate position, the extension of the second telescopic cylinder 147 can send the pneumatic finger 148 to the top of the receiving box 5. At this time, the pneumatic finger 148 can be controlled to release the waste material, which falls into the receiving box 5. This structure can automatically grip the waste material, which is very convenient to use.
