Description

Technical Field

[0001] This utility model relates to the field of plastic hollow board preparation and shaping technology, specifically, a hollow board shaping device. Background Technology

[0002] Hollow plastic sheets are hollow structural panels made from plastic raw materials such as polypropylene (PP) and polyethylene (PE). They are lightweight, environmentally friendly, and durable, and are widely used in packaging, construction, advertising, transportation, electronics, and agriculture. Their main advantages include good mechanical properties (such as good toughness, impact resistance, and high compressive strength), thermal and sound insulation, waterproof and moisture-proof performance, and recyclability. Furthermore, hollow plastic sheets offer flexible dimensions and relatively low cost, gradually replacing some cardboard products.

[0003] During the molding process of plastic hollow sheets, molding cooling is required after the material is extruded. Cooling methods include using circulating cooling water to indirectly cool the mold, thereby reducing the temperature of the extruded part.

[0004] Current hollow board forming equipment typically uses two water-cooled molds, one above the other, through which the material passes and cools. However, during the assembly of the upper mold in current forming devices, to improve assembly stability, the upper mold is usually connected to a lifting plate via multiple support columns. To ensure the parallelism of the upper mold during installation, each support column requires multiple adjustments after installation to guarantee even cooling of the material. These repeated adjustments result in low production efficiency for the hollow board forming equipment during the assembly process and place high demands on the operators. Utility Model Content

[0045] The support rod 10 is provided with a limiting disc 13 coaxially arranged at a portion provided with the second thread 12, an outer diameter of the limiting disc 13 is smaller than an inner diameter of the through hole, and the limiting disc 13 is used for limiting the fitting depth of the positioning flange plate 9.

[0046] In this way, by arranging the thread holes with same depth, it is ensured that the support rod 10 fitted into the top surface of the upper water-cooled sizing mold 7 has same distance of extending into the top surface of the upper water-cooled sizing mold 7, and the installation accuracy is ensured. Meanwhile, by arranging the limiting disc 13 on the support rod 10, the limiting disc 13 passes through the through holes on the lifting platform 6 in the assembly process, and then the limiting disc 13 is used for limiting the fitting depth of the positioning flange plate 9 into the second thread 12, so that it is ensured that the distance between each positioning flange plate 9 and the upper water-cooled sizing mold 7 is same, and the distance between the upper water-cooled sizing mold 7 and the lifting platform 6 after the positioning flange plate 9 is connected with the lifting platform 6 through positioning is ensured to be same.

The bottom surface of the reinforcing flange plate 21 is arranged in close contact with the top surface of the lifting table 6. Second positioning holes 22 are arranged on the disc surface of the reinforcing flange plate 21. Thread grooves are arranged in the second positioning holes 22.
