Abstract
The invention discloses a passenger car tire shield production technique, which belongs to the production technical field of tire protection products and is characterized by adopting a compression molding forming technique, which sequentially includes unfolding molding, cutting and finished product fabrication. The technique can effectively solve the product negative angle problem, greatly lower die cost without secondary action on dies and is characterized by beautiful product appearance, good rigidity and flexibility, stable performance, safety and environment protection and the special applicability to the protection against top quality passenger car tires.
Description
One, technical field
The invention discloses a kind of production technology of passenger vehicle tyre shield, belong to tire Protection Product production technical field.
Two, background technology
Passenger vehicle tyre shield main and front and back bumper and beater or beat-up applying, can effectively reduce automotive wheels makes an uproar, the foreign material such as stone that tire has got rid of in the vehicle traveling process obtain efficient buffer, and effectively isolated water, ice and snow, thereby prevent aqueous corrosion that panel beating got rid of by tire, get rusty; Automobile industry main flow situation is at present, and the forward and backward tire guard shield of high-grade passenger car has, and low and middle-grade car is subjected to the cost restriction not assemble rear wheel cover, and preceding wheel cover only is housed; Tyre shield generally adopts Shooting Technique or plastic uptake explained hereafter at present, the zone that the product distortion is big, outward appearance out-of-flatness; And plastic uptake technology can only the shaped article thinner thickness, the simple product of moulding; And the equipment investment of Shooting Technique is bigger, and the product surface of producing has inevitable sprue gate, and apparent mass is relatively poor.
Three, summary of the invention
Purpose of the present invention is intended to overcome the deficiency of above-mentioned prior art, disclose a kind ofly be easy to assemble, the production technology of stable performance, passenger vehicle tyre shield safe and reliable, elegant in appearance.
For achieving the above object, the technical solution used in the present invention is: a kind of production technology of passenger vehicle tyre shield, and its special character is that it has adopted mould pressing process, in turn includes the following steps:
1, launch moulding: after the material that will make tyre shield is heated to 150-300 ℃, put into the mould that matches with the tyre shield expansion shape, carry out compression molding under the clamping pressure of 30-35MPa, pressurize is after 30～70 seconds, Qi Mo, taking-up pressing;
2, cutting: adopt die-cut by the shape of tyre shield above-mentioned pressing or the water cutting technique is cut out and cut out the tyre shield semi-finished product, and process corresponding mounting hole site thereon;
3, finished product is made: with above tyre shield semi-finished product repair, combined binding can obtain the tyre shield finished product.
The present invention compares with existing plastic uptake, injection molding process, and this technology can effectively solve product negative angle problem, and mould need not secondary action, invest little, stable molding, apparent mass is good, be convenient to advantages such as assembling, the product design one integrated mass, elegant in appearance, the class height, hard and soft degree well, stable performance, safety and environmental protection can satisfy high-grade passenger vehicle tyre requirement of shelter to greatest extent.
Four, the specific embodiment
For understanding the present invention better, it is done to set forth in further detail below in conjunction with specific embodiment.
Embodiment 1: adopting MODIFIED PP is that raw material produces the front tyre guard shield with car, after at first MODIFIED PP being heated to 150-300 ℃, put into the mould that matches with front tyre guard shield expansion shape, under the clamping pressure of 30-35MPa, carry out compression molding, after the pressurize 30～70 seconds, Qi Mo takes out pressing; Then this pressing is cut out by the shape need employing clicking technique of front tyre guard shield and cut out semi-finished product, and process corresponding mounting hole site thereon; At last semi-finished product repaired, be front tyre guard shield finished product behind the combined binding.
Embodiment 2: adopt felt materials to produce the rear tyre guard shield of passenger car, after at first felt materials being heated to 150-300 ℃, put into the mould that matches with rear tyre guard shield expansion shape, under the clamping pressure of 30-35MPa, carry out compression molding, after the pressurize 30～70 seconds, Qi Mo takes out pressing; Then this pressing is cut out by the shape need employing water cutting technique of rear tyre guard shield and cut out semi-finished product, and process corresponding mounting hole site thereon; At last semi-finished product repaired, be rear tyre guard shield finished product behind the combined binding.
Forward and backward tire guard shield with the foregoing description production, can effectively reduce doughnut makes an uproar, effectively cushion the foreign material such as stone that tire has got rid of in the driving process, effective isolated water, ice and snow, avoid aqueous corrosion that panel beating got rid of by tire, get rusty, prolong the panel beating life-span, can improve the comfortableness of passenger car greatly.
