Abstract
The invention relates to a spraying plastic method for the inner side wall of a machine cabinet hole, which comprises the following steps: (1) punching out an aluminum cushion block in a shape like the Chinese character of 'kou' by a punch press, wherein the length and width size of a square inner hole of the aluminum cushion block is larger than the diameter size of a through hole of the machine cabinet; (2) basically aligning the central lines of the aluminum cushion block and the machine cabinet and arranging the aluminum cushion block on the inner surface of the machine cabinet; (3) fixedly attaching the aluminum cushion block to the inner surface of the machine cabinet on the periphery of the machine cabinet through hole by a high temperature adhesive tape; and (4) spraying, roasting and tearing off the high temperature adhesive tape and removing the. aluminum cushion block. The thickness of molding powder on the inner side wall of the hole is uniform without burrs. Compared with the prior art, the spraying plastic method for the inner side wall of the machine cabinet hole has reasonable process, and the thickness of the obtained molded powder of the inner side wall of the hole is uniform without the burrs and stacking molding. The consistency of a product is good, so that the product can be widely applied to spraying plastic of panel beating pieces, die-casting pieces, machining workpieces and so on, and is particularly suitable for parts which do not allow stacking molding on the inner side wall of the through hole and can perform single surface spraying.
Description
Technical field
The present invention relates to the rack plastic-blasting method, especially relate to a kind of plastic-blasting method of inside wall of machine cabinet hole.
Background technology
Rack is as the clothes of the sub-device of communication, and effect is to provide to a certain degree protection for being contained in its inner product, makes it farthest to bring into play performance.In order to guarantee good electrical conductivity, in the rack non-plastic-blasting zone is arranged usually.At present, for the regional area rack of plastic-blasting not, the methods of pasting high temperature gummed tape that adopt hide more before the plastic-blasting, adopt this method to carry out the enclosure product of monolateral plastic-blasting, heap is moulded the junction that easily is created in adhesive tape and rack through hole, and promptly the madial wall edge, hole of the non-plastic-blasting face of rack causes that this hole dimension is less than normal, there is heap to mould burr, thereby can not satisfies the installation requirement of mating holes.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of technology is reasonable, plastic-blasting evenly, the plastic-blasting method of the inside wall of machine cabinet hole of good product consistency.
Purpose of the present invention can be achieved through the following technical solutions: a kind of plastic-blasting method of inside wall of machine cabinet hole is characterized in that this method may further comprise the steps:
(1) go out the aluminum cushion block of square shape with punch press, the length and width size of this aluminum cushion block square endoporus is greater than the diameter dimension of rack through hole;
(2) center line of aluminum cushion block with the rack through hole alignd substantially, aluminum cushion block places the rack inner surface;
(3) with high temperature gummed tape aluminum cushion block fixedly is attached to rack through hole rack inner surface on every side;
(4) plastic-blasting, high temperature gummed tape is torn in baking, takes away aluminum cushion block, and the molding powder thickness on the madial wall of hole is even, no burr.
About the diameter dimension 10mm of the length and width size of described aluminum cushion block square endoporus greater than the rack through hole.
The monolateral 10mm that is no less than in the junction of described high temperature gummed tape and rack inner surface.
Compared with prior art, the plastic-blasting method technology of inside wall of machine cabinet hole of the present invention is reasonable, the method that adopts the aluminum backing plate that through hole madial wall edge and high temperature gummed tape are separated, molding powder without hindrance every through the via hole madial wall, the molding powder thickness that guarantees the hole madial wall is even, no burr, Wu Dui mould, and good product consistency can be utilized sheet material waste-material-preparing aluminum cushion block, the aluminum cushion block stamp is simple simultaneously, the stickup aspect is easy to produce in batches, saves cost; Can be widely used in the plastic-blasting of sheet metal component, die casting and machined piece etc., be particularly suitable for the single face plastic-blasting, the through hole madial wall does not allow to pile the part of moulding.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the cutaway view of the A-A of Fig. 1.
The specific embodiment
The invention will be further described for the contrast drawings and the specific embodiments below.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of plastic-blasting method of inside wall of machine cabinet hole, this method may further comprise the steps:
(1) goes out the aluminum cushion block 2 of square shape with punch press, about the diameter dimension 10mm of length and width size greater than rack through hole 1 of these aluminum cushion block 2 square endoporus;
(2) center line of aluminum cushion block 2 with rack through hole 1 alignd substantially, aluminum cushion block 2 places the rack inner surface;
(3) with high temperature gummed tape 3 aluminum cushion block 2 fixedly is attached to rack through hole 1 rack inner surface on every side, the monolateral 10mm that is no less than in junction of high temperature gummed tape 3 and rack inner surface;
(4) plastic-blasting, high temperature gummed tape 3 is torn in baking, takes away aluminum cushion block 2, and the molding powder thickness on the madial wall of hole is even, no burr.
Claims (3)
1. the plastic-blasting method of an inside wall of machine cabinet hole is characterized in that, this method may further comprise the steps:
