The buffer assembly includes a plurality of buffer grooves 10 arranged on the upper mold 8, and the inner walls of the plurality of buffer grooves 10 on one side away from the lower mold 5 are fixedly connected to buffer springs 11, and the ends of the plurality of buffer springs 11 away from the support plate 6 are fixedly connected to buffer rods 12, and the plurality of buffer rods 1 2 are respectively slidably connected in a plurality of buffer grooves 10, a plurality of buffer rods 12 are each provided with a clamping groove 13, a plurality of inner walls of the clamping grooves 13 are each fixedly connected with a telescopic spring 14, a plurality of other ends of the telescopic springs 14 are each fixedly connected with a clamping block 15, a plurality of the clamping blocks 15 are each wedge-shaped, a plurality of inner walls of the buffer grooves 10 are each provided with a clamping groove, a plurality of the clamping grooves are respectively matched with a plurality of the clamping blocks 15, an upper mold 8 is provided with two working chambers 16, a telescopic pump is fixedly connected to the inner walls of the two working chambers 16, and an adjusting plate is fixedly connected to the telescopic ends of the two telescopic pumps;

[0025] The two adjustment plates slide in the two working chambers 16 respectively, and the ends of the two adjustment plates away from the telescopic pump are fixedly connected with multiple push rods 17, and the multiple push rods 17 slide through the upper mold 8 and are respectively slidably connected in multiple card slots.

[0026] During the use of the utility model, the user places the device at a designated workplace. When the device needs to perform injection molding, the hydraulic pump 7 starts to work, and the output end of the hydraulic pump 7 drives the upper mold 8 to move, so that the upper mold 8 slides on the guide rail 9, thereby improving the stability of the upper mold 8. The buffer rod 12 located on the upper mold 8 will first contact the lower mold 5.

At this time, the telescopic spring 14 is reset, and the block 15 will move into the slot. The block 15 fixes the buffer rod 12 to prevent the buffer rod 12 on the buffer spring 11 from exerting a repulsive force on the lower mold 5, making the contact between the upper mold 8 and the lower mold 5 more stable. When the upper mold 8 and the lower mold 5 are completely in contact, the injection molding component 4 fills the lower mold 5 with raw materials, and then coolant is introduced into the cooling pipe 19 to achieve rapid cooling, so that the raw materials are quickly molded, thereby improving the production efficiency of the device. When the injection molding is completed, the hydraulic pump 7 drives the upper mold 8 to reset, and the user takes out the product. At the same time, the telescopic pump starts working, and the telescopic end of the telescopic pump drives the ejector rod 17 to slide in the working chamber 16. The ejector rod 17 ejects the block 15 located in the slot. At this time, the block 15 releases the restriction on the buffer rod 12. At this time, the buffer spring 11 is reset, so that the buffer rod 12 is reset, which is convenient for the device to perform the next injection molding work.
