[0040] An inclined auxiliary material discharge mechanism 7 is provided at the top of the back of the mounting frame 1;

[0041] The tilting auxiliary discharge mechanism 7 includes a mounting long box 701, a mounting long shaft 702, a limiting ring 703, a discharge inclined plate 704, and a buffer sheet 705;

[0042] A mounting box 701 is fixedly connected to the top of the back of the mounting frame 1. A mounting shaft 702 is rotatably mounted through the middle of one side of the mounting box 701. Limiting rings 703 are threadedly installed at both ends of the mounting shaft 702 at positions corresponding to the outer side of the mounting box 701. A discharge ramp 704 is fixedly mounted to the middle of the outer side of the mounting shaft 702. A buffer sheet 705 is adhered to the top of the inner side of the discharge ramp 704. The side of the limiting ring 703 is tightly fitted to the end face of the mounting box 701, and the bottom surface of the buffer sheet 705 is flush with the bottom surface of the inner side of the discharge ramp 704.

[0043] The working principle and usage process of this utility model: In the actual application process, when using a foaming device to produce foamed elastomer, the lifting drive rod 2 drives the foaming punch 3 and the foaming die 4 to close the mold. Then, the raw material is injected into the mold cavity between the foaming punch 3 and the foaming die 4 through the injection structure to ensure that the raw material can foam normally inside the mold cavity.

[0044] Furthermore, during the descent of the foaming punch 3, the driving disc 509 drives the driving telescopic rod 507 to overcome the elastic force of the support spring 508 and move downward. During the downward movement of the driving telescopic rod 507, the transmission cross 506 drives the lifting guide rod 503 and its connected components to descend synchronously. After the foaming punch 3 and the foaming die 4 are closed, the limiting base plate 502 can be embedded into the mounting tapered groove 501, and the top surface of the limiting base plate 502 is kept flush with the bottom surface of the inner cavity of the foaming die 4.

[0045] When the foaming punch 3 and the foaming die 4 are separated after foaming is completed, the guide spring 504 and the support spring 508 simultaneously drive the limiting base plate 502 and the drive telescopic rod 507 to rise. During the rising of the limiting base plate 502, the foamed workpiece is pushed out of the foaming die 4, realizing the demolding of the foamed elastomer. Through the cooperation between the limiting base plate 502 and the drive telescopic rod 507, the demolding and separation process of the foamed elastomer is optimized, thereby effectively improving the convenience of operation of the foaming device.

[0046] When it is necessary to collect the exhaust gas generated during the operation of the foaming device, the collecting fan 602 can generate a continuous negative pressure inside the collecting flat box 604, thereby collecting the exhaust gas emitted from the side of the foaming mold 4 through the collecting flat box 604, and introducing the exhaust gas into the washing box 601 through the collecting air duct 603. The washing liquid inside the washing box 601 absorbs the harmful components in the exhaust gas, and then the filtered exhaust gas is introduced into the blowing side box 606 through the discharge side pipe 605. The blowing side box 606 blows the filtered exhaust gas towards the foaming mold 4, thereby cooling the foaming mold 4 through continuous airflow. This optimizes the exhaust gas treatment and cooling process during the use of the foaming device, and further improves the environmental friendliness of the foaming device.

[0047] When it is necessary to discharge material from the foaming device, the mounting long shaft 702 and its components are installed on the back of the mounting frame 1 through the mounting long box 701. After loosening the limiting ring 703, the tilt angle of the discharge ramp 704 is adjusted, and the foamed elastomer after demolding is guided to discharge through the discharge ramp 704. Then, the buffer film 705 is used to buffer the foamed elastomer falling to the top of the discharge ramp 704, thereby effectively preventing the foamed elastomer from being damaged by collision during the falling process, and effectively improving the convenience of material discharge from the foaming device.
