The top surface of the lower mold 3 has two mounting grooves 8 located on the left and right sides inside the left and right adjusting blocks 5 and 6, arranged along the front-back direction. A shaping block 9 is installed in the mounting grooves 8. A series of air suction grooves 10 are respectively provided on the bottom surface of the upper mold 1, the top surface of the lower mold 3, the inner side of the left adjusting block 5, and the inner side of the right adjusting block 6. The upper mold 1, the lower mold 3, the left adjusting block 5, and the right adjusting block 6 are arranged along the front-back direction... The upper mold 1 is provided with an air hole 11, the front and rear ends of which are connected to a vacuum pump via air pipes. The air hole 11 is connected to the suction groove 10. The top surface of the upper mold 1 is provided with an upper cooling circulating water tank 1a. The upper mold cover plate 2 is provided with a water inlet and a water outlet corresponding to the upper cooling circulating water tank 1a. The bottom surface of the lower mold 3 is provided with a lower cooling circulating water tank 3a. The lower mold cover plate 4 is provided with a water inlet and a water outlet corresponding to the lower cooling circulating water tank 3a. When the upper mold cover plate 2 is closed, it seals the upper cooling circulating water tank 1a. When the lower mold cover plate 4 is closed, it seals the lower cooling circulating water tank 3a. The cross section formed by the upper mold 1, lower mold 3, shaping block 9, left adjusting block 5, and right adjusting block 6 corresponds to the cross section of the extruded die product.

[0018] In the above scheme, the lower mold 3 is fixed on the base plate 12, and the driving mechanism 7 includes a fixed seat 71 connected to the base plate 12. An adjusting screw 72 is threadedly connected to the fixed seat 71. An adjusting nut 73 is connected to the end of the adjusting screw 72 located outside the fixed seat 71. The inner end of the adjusting screw 72 is connected to the connecting block 74. The connecting block 74 is fixedly connected to the left adjusting block 5 or the right adjusting block 6.

[0019] In addition, there are two drive mechanisms 7 on the outer side of the left adjustment block 5, which are respectively connected to the front and rear of the left adjustment block 5; there are two drive mechanisms 7 on the outer side of the right adjustment block 6, which are respectively connected to the front and rear of the right adjustment block 6.

[0020] In addition, the bottom plate 12 is connected to vertically arranged guide columns 13 on the left and right sides of the upper mold 1, and the top surface of the guide column 13 is connected to a fixing plate 14. A cylinder 15 is arranged in the middle of the fixing plate 14, and a pull plate 16 is connected to the bottom of the piston rod of the cylinder 15.

A gap is left between the strip-shaped retaining strip 93 and the right adjusting block 6 or the left adjusting block 5. This gap is adjusted by the driving mechanism 7.

[0022] The working principle of this invention is as follows:

[0023] After the molten raw material is extruded from the lip of the extrusion die, it enters the upper die 1 and lower die 3 of this invention. The shape of the product is consistent with the cross-section formed by the upper die 1, lower die 3, shaping block 9, left adjusting block 5, and right adjusting block 6. The suction grooves 10 provided on the lower surface of the upper die 1, the upper surface of the lower die 3, the inner side of the left adjusting block 5, and the inner side of the right adjusting block 6 are connected to a vacuum device through air holes 11 and air pipes, so that the product is subjected to a uniform outward suction force when it enters the channel, maintaining the shape of the product. At the same time, since the temperature of the product is still relatively high at this time, it needs to be cooled. Therefore, an upper cooling circulating water tank 1a is provided in the upper die 1, and a lower cooling circulating water tank 3a is provided in the lower die 3. The product can be cooled quickly when it passes through the channel, achieving shaping and accelerating solidification. Finally, the product is basically in a solidified and shaped state when it exits from the rear end.

Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present invention shall still fall within the scope of the technical solution of the present invention.
