[0002] The injection molding machine can shape plastic products in one step. Plastic molding molds can be used to make plastic products of various shapes. The injection molding machine can heat the plastic to make it molten. The waste gas generated by the injection molding machine needs to be treated in time, because the waste gas from the injection molding machine is relatively dispersed. If the waste gas is uniformly pumped through the workshop, the collection effect is not good, and the waste gas concentration in the workshop is still very high, which has a great impact on the health of employees.
[0003] The waste gas generated by the injection molding machine is mainly generated when the injection molding machine is separated from the mold. At this time, the concentration of the waste gas is the highest. However, the existing technology lacks a targeted waste gas collection device.
[0004] Therefore, how to provide an exhaust gas treatment device for an injection molding machine to solve the problems existing in the prior art is of great significance to its application. Utility Model Content
[0005] In view of this, the purpose of the present application is to provide an exhaust gas treatment device for an injection molding machine to solve the problem that the prior art lacks a targeted exhaust gas collection device.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A waste gas treatment device for an injection molding machine includes a mold fixing plate, a horizontal plate is fixedly connected to one side of the top of the mold fixing plate, a lifting cylinder is installed on the top of the horizontal plate, an air intake pipe is fixedly connected to the telescopic end of the lifting cylinder, the two ends of the air intake pipe are respectively connected to a first air collecting hood and a second air collecting hood, a fan is installed on the top of the horizontal plate, and the air inlet end of the fan is connected to the air intake pipe through a connecting pipe.
[0008] Preferably, the air intake pipe is arranged transversely, and an injection nozzle is provided on one side of the mold fixing plate close to the first air collecting hood, and the injection nozzle is connected to an injection flow channel.
[0009] Preferably, a heating tube is provided on one side of the second air collecting hood, an injection head is installed at the end of the heating tube, and the injection head is adapted to the injection nozzle.
[0010] Preferably, the first air collecting hood and the second air collecting hood are both trumpet-shaped.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The utility model can collect waste gas in a targeted manner. When in use, when the injection head of the injection molding machine is separated from the injection nozzle on the mold fixing plate, the lifting cylinder drives the suction pipe to descend, so that the two air collecting hoods respectively cover the injection head and the injection nozzle, and then turn on the fan to collect the waste gas volatilized by the injection head and the injection nozzle in time.
