Description

Technical Field

[0001] This utility model relates to the field of vacuum forming equipment technology, specifically to automated sheet vacuum forming equipment. Background Technology

[0002] In the production process of acrylic bathtubs, the acrylic sheet is first fixed, and then softened by heating or high temperature. A vacuum forming device is used to shape the acrylic sheet. Existing vacuum forming devices mainly consist of molds, clamps, and vacuum pumps. The clamps are used to fix the sheet, and then the sheet is placed into the mold, so that the mold and the sheet form a sealed space. The vacuum pump creates negative pressure in the sealed space, which allows the softened sheet to be deformed into the shape of a bathtub.

[0003] A search revealed a patent, CN208730347U, which discloses a vacuum forming device for acrylic bathtubs. The key technical features include a vacuum forming cavity, a fastening mechanism for fixing the sheet material to the edge of the cavity opening, and a vacuum pump connected to the cavity via a pipeline to create negative pressure. Sliding mechanisms are provided on both symmetrical surfaces of the cavity. Each sliding mechanism is equipped with a light source emitter and a photoelectric receiver, which are synchronously driven vertically by the sliding mechanisms. The light source emitter and photoelectric receiver are at the same horizontal position.

If large particles of impurities fall into the mold, it will reduce the quality and appearance of the vacuum-formed bathtub. Therefore, there is an urgent need in this field to improve automated sheet metal vacuum forming equipment to solve the defects of the existing technology. Utility Model Content

After vacuuming is completed, the vacuum forming sheet 8 is also heated. Then, the first drive motor 19 drives the first sliding seat 5 and the second sliding seat 6 to move in opposite directions. When the vacuum forming sheet 8 moves above the mold body 3, several... The second telescopic device 15, with its telescopic end driving the carrier plate 2 upward, causes the upper part of the mold body 3 to be tightly attached to the lower part of the sheet material 8 to be vacuum-formed. The vacuuming device, such as a vacuum pump, connected to the second connecting hose 17 is activated. Through the cooperation of the hollow box 16 and several vacuum forming holes 18, the cavity inside the mold body 3 is evacuated, creating a negative pressure inside the mold body 3.
