Description

Hot-press molded motorcycle cushion and hot-press molding process
Technical Field
The invention relates to the technical field of motorcycle seat cushions, in particular to a hot-press molded motorcycle seat cushion and a hot-press molding process.
Background
The seat cushion of a motorcycle is generally formed of a facing layer, an intermediate layer and a floor plate which is connected to a frame. The surface layer is generally made of leather, the middle layer is formed by foaming through a foaming material, a large piece of leather is generally placed in an upper die in the production process of the existing seat cushion, then the liquid foaming material is injected into a lower die, the upper die and the lower die are combined and vacuumized, then heating is carried out to enable the foaming material to be molded, and the foaming material and the leather are integrally molded in the molding process. However, the volume of the foaming material expands in the foaming process, and the foaming material is wrapped by the leather, so that the foaming material cannot leak out after vacuumizing, the whole area of the leather is generally large, and redundant leather needs to be cut off after foaming is finished; if the leather has been cut to size beforehand, there is a risk of air leakage during the foaming process, resulting in incomplete foaming. The mode of foaming by coating the foaming material on the whole piece of leather can cause the waste of the leather.
Disclosure of Invention
The invention provides a hot-press formed motorcycle cushion and a hot-press forming process, aiming at the problem that the material is wasted due to the fact that a large area of leather coated foaming material is adopted for foaming at present.
In order to achieve the above object, the present invention provides the following technical solutions:
on one hand, the invention provides a hot-press formed motorcycle cushion which comprises a leather layer, a hot-press film and a middle layer, wherein the hot-press film is positioned between the leather layer and the middle layer, the leather layer, the hot-press film and the middle layer are integrally formed in a hot-press forming mode, the hot-press film is heated and then is adhered to the leather layer and the middle layer, and the shape of the leather layer is matched with that of the middle layer.
Preferably, the hot-pressing film is a waterborne polyurethane hot-melt adhesive film or a hot-melt adhesive or hot-melt powder.
Preferably, the middle layer is made of foam, and the foam is foamed and molded before hot-press molding. The foam is light in weight and good in rebound resilience.
Preferably, the motorcycle cushion further comprises a bottom plate, and the middle layer is connected with the bottom plate. The leather layer is connected with the bottom plate after being hot-pressed with the middle layer, concave-convex corresponding points are arranged on the middle layer and the bottom plate, connection is convenient, and the middle layer can be placed to slide and shift.
Compared with the prior art, the invention has the beneficial effects that: the application provides a motorcycle cushion's intermediate level lies in that the leather layer just is foaming forming before connecting, increase the hot pressing membrane between leather layer and intermediate level, then make leather layer and intermediate level be connected through the mode of hot pressing, in-process at hot pressing just need not adopt the vacuum, consequently the size of the leather on leather layer only need cut out corresponding size in advance according to the condition can, the material of the leather of needs just need not so much, also need not cutting out the leather layer after last hot briquetting, the leather can be in batches when cutting out in advance, needn't be like the material after the foaming completion to cut out of one, so both saved the material and also practiced thrift the manual work of cutting out.
On the other hand, the application also provides a hot press molding process of the motorcycle cushion, which comprises the following steps:
s1, foaming and forming an intermediate layer material;
s2, placing the foamed middle layer on a lower die, placing a hot-pressing film on the middle layer, and placing a leather layer on an upper die;
and S3, closing the upper die and the lower die and carrying out hot pressing.
Preferably, in the step S3, the temperature during hot pressing is 180 to 230 ℃, and the time during hot pressing is 20 to 180 seconds.
Preferably, heating mechanisms are arranged in the upper die and the lower die respectively, and the heating mechanisms are one or more of electric heating wires, water vapor or hot oil. Heating mechanisms are arranged in the upper die and the lower die, so that the hot pressing time can be shortened.
Compared with the prior art, the invention has the beneficial effects that: before the leather layer is connected with the middle layer, the middle layer is foamed by adopting a liquid foaming material, so that the middle layer is manufactured independently and is irrelevant to the size of leather, and the middle layer can be made of an EVA (ethylene vinyl acetate) material or other materials. The foamed middle layer and the leather layer are connected after being hot-pressed by a hot-pressing film in a hot-pressing mode, the leather layer and the middle layer are connected and integrated after the hot-pressing film is hot-pressed and melted, and therefore the leather layer can be cut before hot pressing according to the size of an actual coating, and extra cutting is not needed after hot pressing.
Description of the drawings:
fig. 1 is a cross-sectional view of a hot-press formed motorcycle seat cushion provided by the present application.
The mark in the figure is: 1-leather layer, 2-hot-pressed film, 3-middle layer.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.
