Embodiment Construction
[0028] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0029] Such as Figure 1-6 As shown, the production process of the spare tire cover comprises the following steps:
[0030] Mold preparation step: hang the valance 10 on the front mold 41 of the mold 40, insert the buckle 20 into the back mold 42 of the mold 40, and the connecting end 21 of the buckle 20 extends out of the back mold 42;
[0031] Pre-production step: making the plastic parison 30 in a softened state;
[0032] Post-processing step: when the plastic parison 30 obtained in the pre-production step is still in a softened state, the plastic parison 30 is placed between the front mold 41 and the back mold 42 of the mold 40 that has completed...

The invention discloses a spare tire cover plate production technology, a mold for the spare tire cover plate production technology and a spare tire cover plate. The spare tire cover plate productiontechnology comprises the following steps of: preparing the mold, to be specific, hanging a drapery fabric on a front mold of the mold, and inserting a buckle into a back mold of the mold, wherein theconnecting end of the buckle protrudes out of the back mold; carrying out preposition manufacturing, to be specific, manufacturing a plastic rubber parison being at a soft state; and carrying out postposition manufacturing, to be specific, putting the plastic rubber parison between the front mold and back mold of the mold subjected to mold preparation, then causing the drapery fabric to be adheredto the plastic rubber parison and the connecting end of the buckle to be inserted and adhered to the plastic rubber parison through the mold closing of the mold, molding and solidifying the plastic rubber parison to form the spare tire cover plate. The spare tire cover plate production technology can save time and improve production efficiency, and can also overcome the technical problems that the manual fabric adhering causes unstable fabric hanging, and further bulges and creases are easily caused; the spare tire cover plate production technology enables the drapery fabric to be firmly hungand have good appearance effect and can ensure the perpendicularity of the buckle so as to meet the requirement on tolerances for products.
Description
technical field [0001] The invention relates to a production process of a spare tire cover, a mold used in the production process of the spare tire cover and the spare tire cover. Background technique [0002] A spare tire cover is often provided on the automobile to be used to cover the spare tire. But at present, in the production process of the spare tire cover, after the plastic parison is formed into the spare tire cover, it is still necessary to manually paste the hanging cloth on the spare tire hanging plate, and manually fasten the buckle The connection end of the spare tire is fixed on the spare tire scraper, which takes a long time, resulting in low production efficiency of the spare tire cover; moreover, the manual sticking of the hanging cloth is prone to technical problems such as weak sticking and easy foaming , far from meeting the needs of the industry. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, one of the o...
