Technical Field

[0001] This utility model relates to the field of deburring technology for plastic products, and in particular to a device for removing burrs from plastic products. Background Technology

[0002] Injection molding is a method in which plastic material, completely molten at a certain temperature by stirring with a screw, is injected into a mold cavity under high pressure, and then cooled and solidified to obtain a molded product. This method is suitable for the mass production of complex-shaped parts and is one of the important processing methods.

[0003] After injection molding, plastic products often develop burrs due to factors such as mold life, mold fitting accuracy, injection molding process, and injection molding machine parameters. These burrs can cause the appearance or function of the plastic products to fail to meet requirements, thus necessitating deburring. Manual deburring with a utility knife is problematic due to inconsistent burr removal quality, low processing efficiency, and the risk of scratching the product and causing workplace injuries.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1-4 This utility model provides a technical solution: a device for removing burrs from plastic products, comprising:

[0035] The frame 1 is provided with a worktable 11, and the worktable 11 is provided with chip removal holes 111;

[0036] Product fixture 2 is fixedly installed on workbench 11. Product 9 to be processed is placed on product fixture 2 and positioned above chip discharge hole 111.

[0037] The air knife module 3 includes movable cylinders 31 symmetrically arranged on both sides of the product tooling 2, and air knives 32 are provided on the sliders of the movable cylinders 31.

[0038] The chip collection bin 4 is located below the workbench 11, and the position of the chip collection bin 4 corresponds to the chip discharge hole 111. The bottom of the chip collection bin 4 is connected to the dust collector 41.

[0039] Door panel 5 is slidably connected to frame 1;

[0040] The door opening cylinder 6 is fixedly installed on the frame 1, and the slider of the door opening cylinder 6 is connected to one side of the door panel 5.

[0041] Air knife 32 is an anti-static ion air knife. A 20L air tank is also integrated on frame 1 to supply air to the air knife. Dust collector 41 is a 20L pneumatic dust collector.

[0042] In the deburring device, the product to be processed 9 is deburred in an enclosed space on the frame 1, effectively preventing material debris from flying around. Simultaneously, dust and deburred waste are collected to avoid polluting the factory environment. The product to be processed 9 is deburred using an air knife within the enclosed space on the frame 1, effectively preventing product scratches and separating operators from the product, thus protecting the operators.

[0043] Door panel 5 is a transparent plastic panel, which makes it easy to observe the deburring process of the product 9 to be processed.

[0044] Working principle: When deburring the product 9 (i.e. the plastic product after injection molding), the door opening cylinder 6 first drives the door panel 5 to slide upward and open. After placing the product 9 on the product fixture 2, the deburring is started by controlling the start button.

[0045] The door opening cylinder 6 drives the door panel 5 to slide down and close. The air knives 32 on both sides of the product fixture 2 in the air knife module 3 blow air onto the product 9 to be processed on the product fixture 2 to remove dust and burrs from the surface of the product 9. While blowing air, the air knife 32 moves up and down with the slider of the moving cylinder 31. After the deburring time reaches the set time, the air knife 32 stops working.

[0046] Then, the dust collector 41 is pneumatically activated, which creates negative pressure at 4 points in the chip collection bin to collect dust and remove burr waste.

[0047] After deburring is completed, the door opening cylinder 6 drives the door panel 5 to open and remove the product 9 to be processed.

[0048] Example 2

[0049] This embodiment further improves upon the above embodiment by providing the following technical solution: The product fixture 2 includes two parallel support frames 21, with symmetrically arranged support legs 211 at both ends of the support frames 21. The two support legs 211 are symmetrically arranged on both sides of the chip removal hole 111. Two parallel positioning rods 212 are also provided on the support frames 21. The product 9 to be processed is placed on the support frame 21, between the two positioning rods 212, so that the burrs and dust cleaned from the product 9 can fall into the chip removal hole 111.

[0050] The positioning rod 212 is a round rod, which effectively avoids scratches when positioning products.

[0051] Example 3

[0052] This embodiment further improves upon the above embodiment by providing the following technical solution: the positioning rod 212 is detachably mounted on the support frame 21. Specifically, the support frame 21 is provided with a slotted hole 213, and the screw of the locking bolt passes through the slotted hole 213 and is threaded onto the positioning rod 212.

[0053] The waist-shaped hole 213 allows the positioning rod 212 to be flexibly disassembled and replaced, and the distance between the two positioning rods 212 can be flexibly adjusted, thereby effectively positioning products of different sizes.

[0054] 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.
