Abstract
The invention provides a method for manufacturing an anti-release structure, which comprises the steps as follows: (1) PP powder and wood powder are mixed and stirred to obtain a mixture; (2), the mixture obtained in the step (1) is extruded to a PP sheet material at the temperature of 210-230 DEG C; (3) then the PP sheet material formed in the step (2) is cooled and cut to required size; (4) the PP sheet material cut in the step (3) is arranged on a base material of a coat and hat rack, then an accessory with a perforation is arranged on the PP sheet material; (5) the three materials superposed in the step (4) are put into a hot pressing mould, hot pressed and mold at the temperature of 210-230 DEG C under the condition that the PP can be melted but not carbonized. By adopting the method for manufacturing the anti-release structure of the invention, connection between the parts and the accessory with the perforation can be realized, and the invention has the advantages of low cost, high efficiency, and simple process without affecting the beautiful appearance of the parts.
Description
Technical field
The present invention relates to a kind of method of making disconnecting prevention structure.
Background technology
In the prior art, the main material of luggage case hat rack is wood flour board or numb fine plate usually, and structure is generally by hot-forming, so can't design complicated structure.When luggage case hat rack and vehicle body location and installation abat vent, its annex adopts the bonding or ultrasonic bonding of silica gel usually, but described two kinds of methods all have weak point.
If adopt silica gel bonding, need to increase separately a procedure, so waste man-hour; When concrete operations, be difficult to the amount of control silica gel, silica gel overflows easily can influence presentation quality, even can influence the gap value between clothing plate and the vehicle body panel beating; Be difficult to accomplish annex is bonded at the exact position; Coming off easily influences part quality and productive temp.
If the employing ultrasonic bonding, then needing equally increases by a procedure, and need increase an equipment; When concrete operations, the difficult control of surface quality of workpieces, burn easily; Coming off easily influences part quality and productive temp.
Therefore, in order to overcome above-mentioned shortcoming, be necessary to invent a kind of method of making disconnecting prevention structure in fact.
Summary of the invention
The objective of the invention is to invent that a kind of cost is low, efficient is high and technology is simply made the method for disconnecting prevention structure.
The method of manufacturing disconnecting prevention structure proposed by the invention is such:
A kind of method of making disconnecting prevention structure may further comprise the steps:
(1) PP powder and wood powder are mixed stirring;
(2) under temperature is 210 ℃-230 ℃ condition, the composite material in the described step (1) is squeezed into the PP sheet material;
(3) then to after the moulding PP sheet cools in the described step (2), the PP sheet material is cut into the use size;
(4) the PP sheet material with described step (3) well cutting is placed on the hat rack base material, and then will have the annex of perforation to be placed on the described PP sheet material;
(5) the three kinds of stack in the described step (4) is good materials are put into hot pressing die, are 210 ℃-230 ℃ in temperature and guarantee that PP melt but under the condition of not carbonization, and are hot-forming.
Preferably, the percentage by weight at PP powder described in the described step (1) and wood powder is respectively 85%, is not more than 15%.
Preferably, can add colorant in described step (1), according to the color of different requirement adjustment colorants, the colorant percentage by weight is 0-0.5%.
Preferably, temperature is 220 ℃ in the described step (2).
Preferably, in described step (2), composite material is squeezed into the PP sheet material with screw rod.
Preferably, the size that is cut at PP sheet material described in the described step (3) compares by the big 10mm of the peripheral size of adhesive.
Preferably, the annex that perforation is arranged in the described step (4) is metal or nonmetal annex.
Preferably, the described hat rack base material in the described step (4) is a flaxen fiber.
Preferably, in described step (5), the hat rack base material is placed on the counterdie of hot pressing die.
Preferably, hot-forming in the described step (5) for carrying out under being 220 ℃ condition in temperature.
By adopting a kind of method of making disconnecting prevention structure proposed by the invention, can realize part and connection between the annex of perforation is arranged that cost is low, efficient is high, and technology is simple, does not influence the good looking appearance of part.
Description of drawings
Fig. 1 is the flow chart of the method for manufacturing disconnecting prevention structure of the present invention.
The specific embodiment
Fig. 1 shows the method flow diagram of manufacturing disconnecting prevention structure of the present invention.As shown in the figure, at first, PP powder, wood powder and coloring material for mixing are stirred, wherein, the ratio of described PP powder, wood powder and colorant is respectively 85%, be not more than 15% and 0-0.5%; Then, be that preferred temperature conditions is 220 ℃, and described composite material is squeezed into the PP sheet material under 210 ℃-230 ℃ the condition in temperature; After the PP sheet material of moulding at room temperature cooled off, again the PP sheet material is cut into the use size, the scope of described use size is generally than by about the big 10mm of the peripheral size of adhesive, for example, if be of a size of 10mm * 20mm by adhesive, then the size of PP plate is 20mm * 30mm at last; The PP sheet material of well cutting is placed on the hat rack base material, and will has the annex of perforation to be placed on the described PP sheet material; The three kinds of good materials that will superpose are then put into hot pressing die, and the hat rack base material are placed on the counterdie of hot pressing die, are 210 ℃-230 ℃ in temperature and guarantee that PP melt but under the condition of not carbonization, preferred temperature conditions is 220 ℃, and is hot-forming.
Wherein, composite material is being pushed, during moulding PP sheet material, preferably adopting the screw rod pressing method, certainly, also can adopt other processes, for example, injecting method.Described hat rack base material is a flaxen fiber.It is described that the annex of perforation is arranged is metal or nonmetal annex, wherein, the effect of the perforation on the annex is: the PP sheet material is filled the perforation of annex through adding hot extrusion, after treating the PP sheet cools, the PP that is filled in the perforation sticks to annex on the hat rack securely just as alignment pin.In addition, can also adjust the color of colorant as requested, to reach overall appearance effect attractive in appearance.
The method of manufacturing disconnecting prevention structure proposed by the invention, not needing increases by a procedure in addition, also do not need to increase other equipment, so cost is low, technology is simple, efficient is high, and can be good at controlling presentation quality, advantage such as will can not come off after the one-shot forming.
It will be understood by those skilled in the art that the present invention is not limited to the description of present embodiment, any in the claim scope of being added change or revise all in the scope of protection of present invention.
