Description

Technical Field

[0001] This utility model relates to a waste gas collection mechanism for injection molding machines. Background Technology

[0002] Plastics produce a pungent odor when heated. When injection molding machines inject plastic into molds, this odor easily escapes from the injection nozzle. If these fumes are not collected and treated in a timely manner, they can easily pollute the ambient air in the production area. Therefore, some people install exhaust gas collection devices near injection molding machines. However, due to the poor placement of the suction port of these devices, exhaust gas collection is still insufficient, which can easily lead to the escape of exhaust gas and pollute the ambient air.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems and provide a waste gas collection mechanism for injection molding machines. This waste gas collection mechanism can perform all-round suction of the waste gas emitted from the injection nozzle and can suck up the vast majority of the waste gas.

[0005] To achieve the above objectives, this utility model provides a waste gas collection mechanism for an injection molding machine, which includes an injection mold, a first air housing, and a second air housing. The injection mold has an injection port on its front side. The first and second air housings are located in front of the injection port and are joined together to form an annular air housing body. An annular air passage is formed inside the air housing body. Multiple air inlets are distributed on the inner annular wall of the air housing body and are connected to the annular air passage. An exhaust port connected to the annular air passage is provided on the air housing body. The first air housing can move relative to the injection mold to move away from the second air housing, and the second air housing can move relative to the injection mold to move away from the first air housing.

[0006] In one or more embodiments, the injection mold is provided with a slide rail, and the first air shell and the second air shell are slidably connected to the slide rail via a slide block. The first air shell and the second air shell slide along the slide rail to splice each other to form the air shell body.

[0007] In one or more embodiments, the slide is provided with a locking screw, which is used to abut against the slide rail to restrict the movement of the slide.

[0008] In one or more embodiments, the slide is provided with a hand-tightening part that connects to the locking screw.

[0009] In one or more embodiments, the slide is provided with a handle.

[0010] In one or more embodiments, the end of the slide rail is provided with an anti-detachment part, which is fixed to the slide rail by screws.

[0011] Compared with the prior art, the advantages of this utility model are: the exhaust gas collection mechanism can comprehensively extract the exhaust gas emitted from the injection nozzle, greatly reducing the escape of exhaust gas, avoiding pollution of the ambient air in the production area, and providing producers with a clean production environment.

[0013] Figure 2 This is a schematic diagram of the structure of the first and second wind shells before they are assembled. Detailed Implementation

[0014] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0015] Please refer to the appendix. Figure 1-2 This application provides a waste gas collection mechanism for an injection molding machine, comprising an injection mold 1, a first air housing 2, and a second air housing 3. The injection mold has an injection port 4 on its front side. The first air housing 2 and the second air housing 3 are located in front of the injection port and are joined to form an annular air housing body. An annular air passage 5 is formed inside the air housing body. Multiple air inlets 6 are distributed on the inner annular wall of the air housing body, communicating with the annular air passage. An exhaust port 7, communicating with the annular air passage, is provided on the air housing body. The exhaust port is used to connect to an exhaust fan. When the exhaust fan is working, exhaust gas is drawn from the air inside the annular air passage. The exhaust gas emitted from the injection nozzle is captured by multiple air inlets and drawn into the annular air duct. The exhaust gas is then discharged through the exhaust vent, thus preventing the exhaust gas from escaping into the ambient air and polluting the air quality of the production area. The first air housing 2 can be moved relative to the injection mold 1 to move away from the second air housing 3, and the second air housing 3 can be moved relative to the injection mold to move away from the first air housing 2. After the injection mold has finished working, the producer needs to clean the residual glue remaining at the injection nozzle. At this time, the first and second air housings can be moved to prevent them from affecting the cleaning of the residual glue at the injection nozzle.

[0016] The injection mold 1 is provided with a slide rail 8. The first air shell 2 and the second air shell 3 are slidably connected to the slide rail through a slide block 9. The first air shell and the second air shell slide along the slide rail to splice each other to form the air shell body. By setting the slide rail, the producer can easily adjust the position of the first air shell and the second air shell by sliding.

[0017] The slide block 9 is equipped with a locking screw, which abuts against the slide rail to restrict the movement of the slide block 9. When it is necessary to use the first and second air shells to draw in exhaust gas, the first and second air shells are first assembled to form the air shell body, and then the locking screw is tightened, locking the first and second air shells so that they cannot slide. Preferably, in order to facilitate tightening and loosening the locking screw, the slide block is equipped with a hand-tightening part 10 connected to the locking screw.

[0018] The slide block 9 is provided with a handle 11, which can be easily pushed to make it slide, so that the producer can adjust the position of the first air shell and the second air shell.

[0019] The slide rail 8 is provided with an anti-detachment part 12 at its end. The anti-detachment part is fixed to the slide rail 8 with screws and can prevent the slide from derailing.

[0020] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
