Summary of the invention
The object of this invention is to provide and make the external corner of hot-press resin plate formed product become angular upper position mould and lower position mould.
Design of the present invention is: in the some position, lower position mould 30 bead angle of upper position mould 31 and lower position mould 30 correspondence, at this bead angle point of lower position mould 30, a triangle top convex 20 is set, make it at lower position mould 30 this corresponding angle position with upper position mould 31, convex 20 angles, top 21, lower position mould 30 triangle top are closer to the inner corner trim intersecting point of upper position mould 31, the hot-press resin plate of position mould 31 angular inner corner trim intersecting point is made to obtain larger squeeze force, when hot pressing, hot-press resin plate is pressed onto the most deep location of the angular inner corner trim intersecting point of upper position mould 31, make hot-press resin plate angular inner corner trim intersecting point of position mould 31 on this intersecting point can be close to, the angular corner configurations of upper position mould 31 angular inner corner trim intersecting point, the external corner being pressed into hot-press resin plate formed product becomes identical angular completely.
Structure of the present invention is:
The external corner of hot-press resin plate formed product becomes the mould of angular corner, lower position mould 30 below and the upper position mould 31 be positioned at during the hot forming matched above is positioned at when comprising hot forming, it is characterized in that: the upper angular spill inner corner trim of position mould 31 is 100-150 degree, to the some position, lower position mould 30 convex bead angle of upper mould 31 angular spill inner corner trim corner being provided with a triangle top convex 20;
The height of projection that convex 20 angles, top 21, this triangle top exceed facial plane on lower this corner of position mould 30 is 0.20-0.30 millimeter, make it at lower position mould 30 this corresponding angle position with upper position mould 31, angle, lower position mould 30 top 21 is closer to the inner corner trim intersecting point of upper position mould 31;
The angle 15-50 degree fewer than the angle of the upper position mould 31 angular spill inner corner trim corner of correspondence position at convex 20 angles, top 21, this triangle top; Make it at lower position mould 30 this corresponding angle position with upper position mould 31, lower position mould 30 matches with the corner of upper position mould 31 with less angle with closer to the position of upper position mould 31;
The hypotenuse of convex 20 the shortest limits, this triangle top and lower this bead angle of position mould 30 is on same straight line.
Mould provided by the invention, the hot-press resin plate be applicable to thickness is 2-3 millimeters thick carries out hot forming, make its this hot-press resin panel products upper surface by the angular external corner of mould heat pressure of the present invention, both produced and can become the angular external corner shape of product upper surface corresponding to upper position mould 31 angular spill inner corner trim corner configurations, increase the aesthetic feeling of hot-press resin plate formed product, more like by consumer.
Because the hypotenuse of convex 20 the shortest limits, this triangle top and lower this bead angle of position mould 30 is on same straight line, when the downward hot-press resin plate of upper position mould 31, triangle top convex 20 only has hypotenuse hot-press resin plate can be extended smoothly, the top on triangle top convex 20 can hinder hot-press resin plate to extend relatively, distally extend the hot-press resin plate portion be obstructed, can only upwards the angular spill inner corner trim of position mould 31 correspondence depths extend, the hot-press resin plate of extension is made to be crowded with angular spill inner corner trim depths of position mould 31, then hot-press resin plate is just hot pressed into the shape of angular convex external corner, realize object of the present invention.
Through test of many times, the hypotenuse of convex 20 the shortest limits, triangle top and lower this bead angle of position mould 30 is on same straight line, the hot-press resin plate of this corner can be extended smoothly oblique, and on top it extends by obstruction to a certain degree, just likely realize the object that hot-press resin plate is hot pressed into the shape of angular convex external corner.
Enumerate lower position mould 30 architectural feature of angle position corresponding to several special edge of position mould 31 dihedral corner below:
One, when the angular spill inner corner trim of upper position mould 31 is 100 degree, lower position mould 30 is provided with a triangle top convex 20 in this some position, convex bead angle;
The height of projection that convex 20 angles, top 21, this triangle top exceed facial plane on lower this corner of position mould 30 is 0.20 millimeter;
