[0041] The material connection structure 5 includes a material buffer component 501;

[0042] The buffer component 501 includes a frame 5012 and a spring piece 5013; the frame 5012 is arranged in the frame 1; a U-shaped frame 5011 is fixed to the side of the frame 1 below the mold assembly 3, and one side of the U-shaped frame 5011 is snap-fitted with one side of the frame 5012; wherein, one end of the U-shaped frame 5011 is arranged in an arc shape; the frame 5012 is directly snapped onto the U-shaped frame 5011, which is convenient for installing or disassembling the frame 5012 and easy to operate; two spring pieces 5013 are symmetrically arranged on both side walls of the frame 5012; wherein, the two spring pieces 5013 are arranged obliquely, and a gap is left between the two spring pieces 5013; a rubber pad 5014 is fixed on the top side of the spring piece 5013, and a good buffering effect is achieved when the plastic bottle contacts the rubber pad 5014; the lower end of the spring piece 5013 and the lower end of the rubber pad 5014 are both arranged in an arc shape, which will not hinder the falling of the plastic bottle.

[0043] The utility model has the advantages of cushioning the falling plastic bottles, slowing down the falling speed of the plastic bottles, and protecting the plastic bottles by arranging the U-shaped frame 5011, the frame 5012 and the spring piece 5013, and solves the problem that the pushed plastic bottles directly fall on the material receiving area below, which has a relatively large impact force on the plastic bottles and is easy to damage the plastic bottles after injection molding.

[0044] An insert 5016 is fixed to the top end of the spring piece 5013 , and a slot 5015 is provided on the top of the side wall of the frame 5012 , and the insert 5016 is plugged into the slot 5015 ; wherein, the insert 5016 is designed in an I-shape, and the insert 5016 is adapted to the slot 5015 .

[0046] Example 2: A plastic bottle injection molding machine with a demoulding mechanism, see Figure 2 and Figure 5 ;

[0047] The material receiving assembly 502 is arranged below the frame 5012;

[0048] The material receiving assembly 502 includes a fixed plate 5021 and a movable plate 5023; the fixed plate 5021 is fixed to the side of the frame 1 below the mold assembly 3; the bottom side of the movable plate 5023 is slidably arranged on the fixed plate 5021 through two symmetrically arranged slide rails 5022; wherein, the groove on the movable plate 5023 corresponds to the bottom outlet of the frame 5012; a sponge pad 5024 is fixedly fitted in the groove on the movable plate 5023, and the plastic bottle contacts the sponge pad 5024 in a soft contact to protect the plastic bottle.

[0050] Working principle: After being injection-molded by the injection molding machine, the plastic bottle is demolded from the mold assembly 3 under the action of the demoulding assembly 4, and the fallen plastic bottle enters the frame 5012 and contacts the rubber pad 5014. Due to inertia, the plastic bottle hits the rubber pad 5014, causing the spring 5013 to bend, thereby slowing down the descent speed of the plastic bottle. The slowed-down plastic bottle falls from between the two springs 5013 onto the sponge pad 5024, and the movable plate 5023 is pulled outward. The plastic bottle is taken out from outside the movable plate 5023, and then the movable plate 5023 is pushed back for continued use.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes.
