Detailed Description
The following description of the present utility model will be further provided with reference to specific embodiments to assist those skilled in the art in a more complete, accurate and thorough understanding of the present utility model.
Example 1
As shown in fig. 1 to 5, the plastic cover plate connecting structure of the present embodiment includes a cover inner plate 100 and a cover outer plate 200, and a hollow structure is provided between the cover inner plate 100 and the cover outer plate 200. The outer edge 201 of the end part of the outer plate 200 of the cover, the upper end of the outer edge 201 of the end part is a boss surface, and the outer side of the outer edge 201 of the end part is an arc surface. An outer plate insert 210 is embedded inside the outer edge 201 of the end part of the outer plate 200 of the cover, and the outer end of the outer plate insert 210 is provided with an upper flanging 211. An inner plate insert 110 is inlaid below the outer end of the inner cover plate 100, and the outer end of the inner plate insert 100 extends out of the outer end of the inner cover plate 100. The outer plate insert 210 and the inner plate insert 110 are sheet metal parts. The inner panel insert 110 is disposed over the outer panel insert 210 and is protected by attaching a heat insulating sheet 400 made of a high temperature resistant material to the hood inner panel 100, and then the outer panel insert 210 and the inner panel insert 110 are welded (e.g., laser welded or other welded forms). The insulating sheet is removed after welding. After the welding, a sealant is coated between the outer edge 201 of the end portion of the outer panel 200 and the outer end of the inner panel 100 to form a sealant layer 500, and the upper flange 211 is wrapped inside the sealant layer 500. The outer side of the sealant layer 500 is an arc surface.
In the embodiment, sheet metal parts are respectively embedded in positions with connection strength requirements of the inner plate and the outer plate of the plastic machine cover, and the two sheet metal parts are connected through laser welding or other welding modes; before welding, manually pasting a heat insulation sheet 400 made of a high-temperature resistant material on the corresponding inner surface of the inner plate according to the welding influence range, so as to prevent the inner plate from being burnt by welding heat and influencing the appearance; the flange is manufactured at the boundary of the sheet metal part of the outer plate to form the edge wrapping effect, and the sealing glue is smeared at the position after welding to prevent the edge wrapping from being exposed, so that the sealing property and the attractiveness can be ensured.
It should be apparent that the embodiments of the present utility model are merely illustrative, and that the implementation of the present utility model is not limited by the above-described embodiments, and various insubstantial modifications of the method concept and technical solution of the present utility model are also within the scope of the present utility model.
