The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Referring to Fig. 1 to Fig. 3, the utility model is a kind of coating mould, is applicable to macromolecular material to be coated on the computer upper shell 13 of being made by metal material, and the coated prod obtaining as shown in Figure 5, is the coated district 14 of macromolecular material shown in frame.Particularly, mould of the present utility model comprises patrix 1 and counterdie 2, wherein, in counterdie 2, be formed with: for place computer upper shell 13 to be covered under hold district 3, moulding macromolecular material compacted under chamber 4, in patrix 1, be formed with: with under hold that district 3 coordinates on the upper forming cavity that holds district, coordinate with compacted under chamber 4, the correspondence of structure and position is readily appreciated that, does not repeat herein.As shown in Figure 3, the upper surface of counterdie 2 is provided with a plurality of charging apertures, and the macromolecular material of melting, from charging aperture pan feeding, enters in compacted under chamber 4 by runner.Before said, in the utility model, adopt multiple feed, guarantee that the product appearance after Overmolded is perfect, junction gapless, does not reliably come off, Given this, in mould of the present utility model, runner is divided into two classes: the end runner and the intermediate flow channel that is positioned at centre position that are positioned at two ends.Wherein, end runner comprises first kind sprue 6, the first kind runner 7 being all connected with first kind sprue 6 and Equations of The Second Kind runner 8, and three forms the Y shape being out of shape; And intermediate flow channel comprises Equations of The Second Kind sprue 9, the 3rd class runner 10 docking with Equations of The Second Kind sprue 9, both have formed linear pattern.First kind runner 7, Equations of The Second Kind runner 8 and the 3rd class runner 10 be the equidistantly capable setting of Horizon all, guarantees that in compacted under chamber 4, charging is everywhere even.
As a kind of improvement, the product quality problem that the erosion inertia of the macromolecular material pouring for fear of high speed may bring, as bubble, rough etc., in first kind runner 7, Equations of The Second Kind runner 8 and the 3rd class runner 10, be equipped with buffering step 11; As shown in Figure 4, buffering step 11 is three, and the shoulder height in close compacted under chamber 4, higher than the shoulder height away from compacted under chamber 4, progressively reduces the flow velocity of pan feeding until do not produce erosion completely.
Referring to Fig. 1, after patrix 1 and counterdie 2 matched moulds, charging aperture is also provided with a spacing briquetting 12 outward, prevents that macromolecular material from flowing backwards or overflowing.
Before we said, under to hold district 3 be to be the part that Fig. 5 is not gone out by frame for " placement " computer upper shell 13(to be covered), here, we need to specify, computer upper shell 13 can be to be directly placed on down and to hold in district 3 after forming out with other equipment in advance, can be also directly under hold the interior moulding in district 3.If directly under hold the interior moulding in district 3, manufacture course of products so of the present utility model is just more simple efficient, adopts mould of the present utility model can really realize the coated computer upper shell 13 of one-shot forming macromolecular material.Therefore, as a kind of improvement, as shown in Figure 1, a side relative with charging aperture is also provided with the feeding mouth that flows into mould for the molten metal material of moulding computer upper shell 13, feeding mouth is dendriform, as shown in Figure 3, comprising: the main feeding mouth 15 of circular hole, be symmetricly set in main feeding mouth 15 both sides and minute pan feeding road 16 being communicated with main feeding mouth 15, be communicated with and hold a plurality of secondary pan feeding passages 17 of district's 3 directions extensions downwards with minute pan feeding road 16.Secondary pan feeding passage 17 has just in time intactly covered and time has held the edge in district 3, guarantees the Forming Quality of computer upper shell 13, prevents deformation of products.Preferred molten metal material is magnesium alloy materials.
So, after treating 13 moulding of computer upper shell, then allow macromolecular material from throat-fed, can form coated district 14(frame as shown in Figure 5 and go out part), by macromolecular material gapless, be coated on reliably the edge of computer upper shell 13.Preferably, as shown in Figure 4, one side computer upper shell 13, near being formed with of charging aperture a plurality of " returning " font snap fit 18, for coated for macromolecular material clamping, further improves coated quality.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
