Description

Technical Field

[0001] The utility model relates to the technical field of injection molding production equipment, in particular to a burr burning removal device. Background Art

[0002] In the production of shell injection molded parts, the shell injection molded parts are formed by molds. When the shell injection molded parts are formed, burrs are easily generated at the parting line of the mold. Therefore, the shell injection molded parts need to be subjected to a burr treatment process after molding.

[0003] Conventionally, in the burr treatment of injection molded parts, first, the operator uses a deburring tool to remove the burrs on the edge of the injection molded part. Second, the operator places an alcohol lamp on the table and then brings the burr part of the injection molded part close to the flame of the alcohol lamp to burn and remove the burrs.

[0004] However, in the above two burr removal processes, it is necessary to first find the burr location of the injection molded part and then remove the burr location. Observing the burr location takes a lot of time, and small burrs are difficult to detect with the naked eye, making the removal efficiency low. Utility Model Content

[0031] A burr burning removal device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0032] Reference Figure 1, the utility model aims to provide an embodiment of a burr burning removal device.

[0033] A burr burning removal device according to an embodiment of the present invention includes a cover box 100, a positioning mechanism and a burning mechanism.

[0034] Specifically, refer to Figure 1 and Figure 2 The positioning mechanism includes a support base 110 and a first power member that drives the support base 110 to rise and fall. The support base 110 is located in the cover box 100. The top of the support base 110 is provided with a positioning portion 120. The positioning portion 120 matches the inner cavity of the shell part. The horizontal outer dimension of the positioning portion 120 is larger than the outer dimension of the support base 110; the burning mechanism includes a flame head 130, a igniter 140 arranged outside the flame head 130, and an air supply pipe 150 for supplying air to the flame head 130. The flame head 130 is located in the cover box 100 and is arranged below the support base 110. The top of the flame head 130 is provided with a plurality of air outlets 160. The plurality of air outlets 160 are arranged along the outer edge of the shell part, and the ignition end of the igniter 140 is arranged near the air outlet 160; wherein, the first power member drives the support base 110 to descend so that the outer edge of the shell part is close to the flame head 130.

[0035] In some embodiments of the present invention, an exhaust pipe 280 is provided on the top of the cover box 100 , and the exhaust pipe 280 is provided with an exhaust fan 290 . The exhaust fan 290 and the exhaust pipe 280 cooperate to extract the smoke inside the cover box 100 .

[0036] It is understandable that smoke is generated during the burning of burrs. The exhaust fan 290 is used to remove the smoke inside the cover box 100, and the smoke is discharged to the outside through the exhaust pipe 280 for external treatment to prevent the smoke from flowing into the workshop and affecting the working environment.

[0037] In some embodiments of the present invention, adjacent side walls of the cover box 100 are respectively provided with a feeding port 300 and a discharging port 310 .

[0038] Reference Figure 5 The feeding port 300 and the discharging port 310 are interconnected, which increases the working space of the operators and facilitates the operators' manual loading and unloading operations.

[0039] In some embodiments of the present invention, a conveying mechanism is provided on the side of the cover box 100 close to the discharge port 310. The conveying mechanism includes a conveyor belt 320 and a motor driving the conveyor belt 320 for conveying. The conveyor belt 320 is used to convey shell parts.

[0040] Therefore, after the shell parts are deburred, the operator transfers the shell parts to the conveyor belt 320 through the discharge port 310, and uses the conveyor belt 320 to transfer the shell parts to the next process.

[0041] In some embodiments of the present invention, referring to Figure 3 The flame head 130 includes a first gas box 170, a second gas box 180, a third gas box 190 and a fourth gas box 200. The first gas box 170, the second gas box 180, the third gas box 190 and the fourth gas box 200 are connected in sequence to form a ring structure. The first gas box 170, the second gas box 180, the third gas box 190 and the fourth gas box 200 are all arranged with a gas outlet 160.

[0042] It is understandable that the flame head 130 is formed by splicing the first gas box 170, the second gas box 180, the third gas box 190 and the fourth gas box 200180. The first gas box 170, the second gas box 180, the third gas box 190 and the fourth gas box 200 are all rectangular structures, which are easy to manufacture and process.

[0043] In some embodiments of the present invention, the gas supply pipe 150 is provided with a distribution valve 210, the gas outlet end of the distribution valve 210 is provided with a connecting pipe 220, and the first gas box 170, the second gas box 180, the third gas box 190 and the fourth gas box 200 are respectively connected to the connecting pipe 220.

[0044] Therefore, the gas pipe 150 distributes the gas to the connecting pipe 220 through the distribution valve 210, so that the first gas box 170, the second gas box 180, the third gas box 190 and the fourth gas box 200 can all receive the gas, ensuring that the gas volume of each gas box is sufficient.

[0045] In some embodiments of the present invention, referring to Figure 4 The bottoms of the first gas box 170, the second gas box 180, the third gas box 190, and the fourth gas box 200 are respectively provided with plug connectors 230. The connecting tubes 220 are plugged into the outer surfaces of the plug connectors 230. The connecting tubes 220 and the plug connectors 230 are connected by clamps 240. Specifically, the connecting tubes 220 are hoses, thereby facilitating the installation and removal of the connecting tubes 220 and the plug connectors 230.

[0046] In some embodiments of the present invention, the first power member is a cylinder 250 , the cylinder body of the cylinder 250 is arranged at the bottom of the cover box 100 , and the piston rod of the cylinder 250 passes through the hollow cavity of the annular structure and is connected to the support seat 110 .

[0047] It is understandable that the cylinder 250 has a fast extension and contraction speed, which is beneficial to improving the deburring efficiency and can avoid interference between the first power component and the flame head 130.

[0048] In some embodiments of the present invention, a collar 260 is provided at the bottom of the support seat 110, and the collar 260 is sleeved on the piston rod. A locking bolt 270 is provided on the outer periphery of the collar 260, and the end of the locking bolt 270 abuts against the surface of the piston rod, thereby facilitating the removal of the support seat 110 from the cylinder 250. Different support seats 110 can be replaced to adapt to the deburring of shell products of different specifications.

[0049] Therefore, this embodiment has the following effects:

[0050] 1. The present invention places the shell-like injection-molded parts on the positioning portion 120 by providing a support seat 110 and a first power member. The positioning portion 120 positions the shell-like parts to ensure that each shell-like part is positioned correctly, which facilitates the subsequent accurate removal of burrs on the shell-like parts. In addition, the first power member is used to drive the support seat 110 to descend, so that the shell-like parts are close to the burning position of the flame head 130, instead of manually moving the shell-like parts close to the burning position, to avoid workers being close to the heat source. After the burrs are removed, the first power member drives the support seat 110 to rise, so that the shell-like parts are away from the burning position.

[0051] 2. The present invention provides a flame head 130, an igniter 140 and a gas pipe 150, and utilizes the igniter 140 to ignite the combustion gas output by the flame head 130, and arranges the gas outlet 160 of the flame head 130 along the outer edge of the shell part. When the shell part approaches the burning position, the flame head 130 can burn and remove the burrs on the edge of the shell part at one time, thereby reducing the time required to observe the shell part, thereby improving the burr removal efficiency.
