Description

Technical Field

[0001] This utility model relates to the field of injection molding waste separation technology, and in particular to a high-efficiency injection molding waste separation device. Background Technology

[0002] As people's living standards continue to improve, their material needs are also increasing. Therefore, in order to meet production needs and improve production efficiency, some hardware parts are usually made by injection molding in the current technology. Injection molding requires a mold. After injection molding, due to the existence of the runner, scrap rods are inevitably generated. Therefore, after demolding, the product and the scrap rods are connected. Workers need to manually remove the scrap rods from the product and then carry out subsequent deburring, assembly and other processes. However, this scrap removal method is inefficient and has high labor costs. If mechanical automation is used to remove scrap, different products have different shapes and sizes, so different clamps and grippers are required, which is costly. Moreover, the scrap rods still need to be removed from the product one by one, so the scrap removal efficiency is still not high and there is a tendency for the scrap rods not to be completely removed.

[0003] A search revealed that Chinese patent CN 221559801 U discloses an automatic injection molding waste separation device, comprising a base, a waste collection trough connected to the base, a lower housing connected to the base, an upper housing connected to the lower housing, a rotating shaft connected to the lower housing, several baffles connected to the rotating shaft, a rotary motor for driving the rotating shaft, and a controller. The lower housing has several through holes at its bottom, the waste collection trough is located directly below the lower housing, the baffles are evenly distributed on the rotating shaft, the upper housing is threaded to the lower housing, the rotating shaft and the baffles are both located inside the lower housing, the length of the baffles is less than the length from the rotating shaft to the bottom of the lower housing, the rotary motor is electrically connected to the controller, and the diameter of the through holes is greater than the diameter of the waste rod.

[0004] However, existing technologies, which collect waste only through spaced-apart holes, cannot guarantee collection efficiency. Utility Model Content

[0035] Reference Figures 1-5 A high-efficiency injection molding waste separation device, comprising:

[0036] The waste separation box 1 includes an inlet 2 and an outlet 3, which are used for feeding the injection molded products and discharging the injection molded products after removing waste, respectively.

[0037] The first slope 4 is fixedly connected inside the waste separation box 1. One side of it is located below the feed inlet 2, and the other side forms a drop opening 23 with the side wall of the waste separation box 1. The position of this side is lower than the side of the feed inlet 2, so that the first slope 4 is tilted towards the side away from the feed inlet 2, and the product placed on it can slide down.

[0038] The rotary drive mechanism 5 is located inside the waste separation box 1, above the first landslide 4.

[0039] The waste separation mechanism includes a rotating shaft 6 installed at the drive end of the rotary drive mechanism 5 and several baffles 7 fixedly installed on the outside of the rotating shaft 6.

[0040] The second slope 8 is located below the first slope 4 and is designed to be offset from the first slope 4. It has openings 9 on both sides of the side wall of the waste separation box 1. Its lower side is located above the bottom of the discharge port 3. The position of the second slope 8 near the discharge port 3 is lower than the height of the side away from the discharge port 3, so that the second slope 8 is tilted as a whole. Products placed on it can slide down toward the discharge port 3.

[0041] The waste discharge mechanism includes a blowing device disposed outside one of the openings 9 and a receiving device disposed outside the other opening 9.

[0042] When using this device, the injection-molded product can be placed into the waste separation box 1 through the feed port 2. While sliding down the first slide 4, the rotary drive mechanism 5 is activated, driving the waste separation mechanism to rotate. The rotating baffle 7 contacts the product, separating the excess waste from the product (the connection between the product and the waste rod has low strength and can easily break with a slight bend. Therefore, due to the squeezing force between the products and the force exerted on the product by the baffle 7, the product easily separates from the waste rod). As the product and waste slide down the second slide 8, a blowing device with an opening 9 on one side blows the waste, causing it to be discharged into the receiving device through the opening 9 on the other side, thus completing the separation of the product and waste. Compared with the existing technology that separates the product and waste through through holes, the waste separation method of this device can effectively improve the efficiency of waste separation and collection.

[0043] As a preferred example of this application, the baffles 7 are evenly distributed on the rotating shaft 6, and the length of the baffles 7 is slightly less than the vertical distance from the rotating shaft 6 to the first landslide 4.

[0044] By using the set baffle 7, and by the rotation of the baffle 7 colliding with the product falling into the waste separation box 1, the waste attached to the product is knocked off the product, thus separating the product from the waste. Furthermore, since the length of the baffle 7 is less than the length from the rotating shaft 6 to the top of the first slope 4, the rotation of the baffle 7 will not be affected by the first slope 4 when the baffle 7 rotates.

[0045] As a preferred example of this application, a vibration motor 10 is provided on the surface of the waste separation box 1. The first slope 4 and the second slope 8 are both connected to the protruding edge 14 provided on the inner wall of the waste separation box 1 by springs 15. The protruding edge 14 is designed as a long rectangle on the inner wall of the waste separation box 1 and is inclined. The inclination angle is the same as that of the first slope 4 and the second slope 8. The springs 15 are arranged at both ends of the protruding edge 14. The bottom of the first slope 4 and the second slope 8 are connected to the top of the corresponding springs 15.

[0046] By setting up a vibration motor 10 to generate mechanical waves, the landslide surface is made to produce directional vibration acceleration, which changes the plastic particles from static friction to dynamic rolling state, making it easier for the product to slide down, reducing the slope angle requirement, and adapting to compact space layout.

[0047] In this application example, the opening 9 is rectangular, and the blowing device includes several fans 11 arranged outside the waste separation box 1. Each of the multiple fans 11 is connected to one of the openings 9 through an air outlet 12.

[0048] By using a number of fans 11, air can be blown onto the upper surface of the second landslide 8, causing the waste material to fall into the receiving device through the opening 9 on the other side. As a preferred example of this application, the number of air outlets 12 are all rectangular, and the height of the number of air outlets 12 is the same as the height of the corresponding opening 9. The number of air outlets 12 are connected to each other to close the corresponding opening 9.

[0049] By connecting the air outlets 12 in pairs to seal the corresponding openings 9, the connected air outlets 12 form a continuous sealed surface, reducing the air leakage rate and preventing external pollutants from entering or internal media from leaking out.

[0050] As a preferred example of this application, the receiving device includes a guide duct 13 installed in another opening 9.

[0051] Through the set guide duct 13, the waste material that enters the guide duct 13 through the opening 9 can be discharged to the outside of the waste separation box 1.

[0052] In this embodiment, a waste collection container is provided on the side of the guide duct 13 away from the waste separation box 1.

[0053] As a preferred example of this application, the waste collection container can be a breathable collection bag, which can be sealed to one side of the guide duct 13 by a clamp to ensure that the separated waste falls into the collection bag in a directional manner. Of course, a receiving box can also be used, which is placed on the outlet side of the guide duct 13 to facilitate the collection of waste.

[0054] As a preferred example of this application, a limiting plate 16 is provided above the second landslide 8 and installed inside the waste separation box 1. The limiting plate 16 is provided with a through-hole 24 on the side near the upper end of the second landslide 8 and the waste separation box 1. The through-hole 24 is connected to the drop-out port 23. The other end of the limiting plate 16 is connected to the upper part inside the discharge port 3 to limit the position of the product and make the product located between the limiting plate 16 and the second landslide 8.

[0055] As a preferred example of this application, the top of the second landslide 8 is equipped with several silicone speed bumps 22. The speed bumps 22 are arc-shaped and are used to slow down the falling speed of the waste material (the product size is much larger than the height of the speed bumps 22 and close to the height of the waste material, so the speed bumps 22 have little obstruction effect on the product itself, but have an obstruction effect on the waste material), so that the blowing device can blow it into the receiving device.

[0056] As a preferred example of this application, a buffer pad 17 is installed at the bottom of the limiting plate 16, and the buffer pad 17 is integrally formed of rubber material.

[0057] The buffer pad 17 can protect the product when it comes into contact with the limit plate 16, preventing damage caused by collision between the product and the limit plate 16.

[0058] As a preferred example of this application, a fixing ring 18 is installed at the inner end of the baffle 7, a fixing hole 19 is provided on the surface of the fixing ring 18, a bolt 20 is movably disposed through the fixing hole 19, and a plurality of threaded holes 21 are provided on the outer side of the rotating shaft 6, the bolt 20 being adapted to the threaded holes 21.

[0059] The fixed ring 18 provides multiple fixing points due to the several threaded holes 21 distributed on the rotating shaft 6. The fixed ring 18 allows for the selection of different hole positions to adjust the installation position of the baffle 7, so as to better clean the waste on the product. Furthermore, by tightening the bolt 20, it is easy to remove the damaged baffle 7 and replace it with a new one.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
