Description

Technical Field

[0001] The utility model relates to a thermoforming machine, in particular to a movable template structure of a multi-station plastic thermoforming machine. Background Art

[0002] At present, a Chinese patent with authorization announcement number 214814088U discloses a hot pressing forming device, including a hot pressing forming bracket, a hot pressing forming motor, a hot pressing forming transmission screw, a hot pressing forming upper mold positioning plate, a heating tube, a hot pressing forming upper mold, a hot pressing forming lower mold and a hot pressing forming lower mold translation mechanism, and the hot pressing forming motor is installed on the hot pressing forming bracket.

[0003] The hot pressing forming device can drive the hot pressing forming lower die to perform reciprocating linear motion through the hot pressing forming lower die translation mechanism. When it is necessary to discharge the material, the hot pressing forming lower die is driven by the hot pressing forming lower die translation mechanism to move out from under the hot pressing forming upper die to discharge the material. When hot pressing is required, the hot pressing forming lower die is driven by the hot pressing forming lower die translation mechanism to reach directly under the hot pressing forming upper die, the hot pressing forming upper die is heated to the required temperature by the heating tube, and then the hot pressing forming motor drives the hot pressing forming upper die to be pressed down through the hot pressing forming transmission screw to perform hot pressing.

[0004] However, the hot pressing forming upper die positioning plate of this hot pressing forming device is fixedly connected to the upper die, and the hot pressing forming upper die positioning plate is respectively connected with guide shafts around the hot pressing forming upper die positioning plate, and the guide shafts and guide sleeves form a moving pair. However, when the hot pressing forming upper die positioning plate is damaged, the entire hot pressing forming device needs to be completely dismantled from top to bottom to remove the hot pressing forming upper die positioning plate from the guide shafts, which makes repair and maintenance inconvenient. Utility Model Content
