Description

Technical Field

[0001] This utility model relates to the field of hot press technology, specifically to a guide and positioning structure for a hot press platen. Background Technology

[0002] In fiberboard production lines, multi-layer hot presses are indispensable core equipment in the hot pressing process. They utilize high temperature and high pressure to hot press the board blanks into shape. The operation of a multi-layer hot press is divided into a closing stage and an opening stage. In the closing stage, the hot press relies on multiple hydraulic cylinders below to lift and close the multi-layer hot press plates above. In the opening stage, the hydraulic cylinders descend, and the press plates separate and descend accordingly. Patent publication number CN203236563U discloses a hot press including a rectangular frame, with multi-layer hot press plates that can move upwards horizontally above the tray. The two ends of the multi-layer hot press plates are clamped to vertical stepped clamps located on the rectangular frame. Each side of the hot press plate has a clamping component that cooperates with the stepped clamps. The plate ejection frame includes a multi-layer shelf corresponding to the position of the multi-layer hot press plates. However, the clamping components only serve as abutment and support, without a guiding structure, resulting in problems such as unsmooth and unstable lifting and sliding of the hot press plates, and a tendency for the hot press plates to tilt. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a guide and positioning structure for the pressure plate of a hot press. The lifting and sliding of the hot press plate is smoother and more stable, effectively preventing the hot press plate from tilting. The guide and positioning structure is simple, easy to disassemble and replace, and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a guiding and positioning structure for a hot press plate, comprising multiple layers of vertically movable hot press plates arranged horizontally within a rectangular frame. The rectangular frame includes two rectangular plates arranged front and rear, with stepped positioning platforms fixedly mounted on the two vertical plates of each rectangular plate. The stepped positioning platform includes an upper stepped plate, a middle stepped plate, and a bottom stepped plate that are sequentially fitted and fixed to each other. The bottom stepped plate is fixed to the vertical plate of the rectangular frame. The stepped surfaces of the upper, middle, and bottom stepped plates are arranged vertically from bottom to top. Guide feet for abutment and support are provided at both ends of the hot press plate. The guide foot located on the corresponding bottom stepped plate is foot one. The guide foot corresponding to the middle step plate is called foot two, and the guide foot corresponding to the upper step plate is called foot three. The outer end of foot one is provided with an abutment protrusion one that can abut against the step surface of the bottom step plate. The abutment protrusion one is provided with a positioning step groove one that slides vertically against the vertical right-angle folded edge inside the rectangular plate frame. The outer end of foot two is provided with an abutment protrusion two that can abut against the step surface of the middle step plate.
