Abstract
The invention relates to a method and a die for manufacturing a double-density shockproof top piece, which comprises a hollow tube die, an upper cover of the hollow tube die is provided with an injecting groove which is provided with a shooting nozzle, two sides of the injecting groove are provided with a plurality of die areas with different thicknesses, the die areas include die areas A with shallower depth and die areas B with deeper depth, the die areas A are internally provided with a plurality of drop pits, the injecting groove is provided with a channel communicated with the die areas, and the die areas of a bottom die are matched with the die areas of the upper cover. When in operation, firstly, resin is injected into the die areas A through the injecting groove to be made into a sole layer, the sole and ABS resin are placed into the die areas B, and resin raw materials are injected again to be cooled for being made into the shockproof top piece which has the characteristics of multilayer density and comfortable wearing and good abrasion resistance. The shockproof top piece can reduce the thickness of the sole under the condition of equivalent abrasion resistance performance of the prior shockproof top piece.
Description
Technical field
The present invention relates to produce a kind of method for the preparation of the dual density shockproof top piece and mfg. moulding die.
Background technology
Sole and ground friction caused heel to wear and tear easily when the pedestrian walked, thereby long-term use not only affects attractive in appearance but also causes falling down easily owing to sole is uneven.Shockproof top piece is a kind of plastic skin be used to being fixed on sole, plays anti-skidding, wear-resisting function.The general macromolecular material that adopts is as the shockproof top piece of making sole, the shockproof product of existing manufacturing generally adopts directly with moulding in the material injecting mould, but no matter adopt which kind of material, all make the shockproof top piece of single density, if select harder material, then sole is really up to the mark and bending effect is bad, causes easily foot fatigue when the pedestrian walks; If select comparatively soft material, although bending property has had guarantee, security performance is bad, then need increase sole thickness if guarantee walking safety, thereby cause sole weight to increase.
Summary of the invention
The purpose of this invention is to provide and a kind ofly make the method for dual density shockproof top piece and a kind of mfg. moulding die is provided, to improve safe, the wear-resisting and non-skid property of product.
The mfg. moulding die of shockproof top piece comprises the hollow pipe mould, it is characterized by:
On be covered with the material feeding groove, at the material feeding groove one material sputtering nozzle is arranged, in the other mould district that has some thickness not wait of material feeding groove, the mould district B that the mould district A that the degree of depth is darker and the degree of depth are more shallow has a plurality of pits in the mould district B, has passage to communicate with the mould district on the material feeding groove.
Bed die is provided with the material feeding groove, and two mould districts is arranged with the mould district of loam cake coupling and be used, and in the mould district A of bed die a plurality of fore-sets is arranged, and in the mould district B of bed die a plurality of pits is arranged, and has passage to communicate with the mould district on the material feeding groove.
Wherein, the fore-set number in the mould district is odd number; The mould district B of bed die has two fixed legs.
A kind of preparation method of shockproof top piece has been utilized the mfg. moulding die of above-mentioned shockproof top piece, and step comprises successively:
(a) TPU with the 80-100 degree expects to make finished product after the cooling by the mould district A of material feeding groove (4) injection loam cake (1);
(b) resin by injection material in hollow pipe mould (3), cooling obtains resin column behind the hot melt, and in the pit (8) with the mould district B of its bed die of packing into (2);
(c) the TPU finished product that makes is placed the mould district A of bed die (2), use again loam cake (1) to cover bed die (2), and by material feeding groove (4) the TPU material of 60-80 degree is added cooling forming behind the mould district B.
In addition, be added with pigment in the used TPU material of injection moulding, the resin material that (b) injects in the step is ABS resin, polyvinyl chloride resin or PET resin.
Shockproof top piece of the present invention has the following advantages: thus can according to the force-bearing situation of sole different parts with contact the material that causes the different arrangement different densities that weares and teares with ground, can avoid the material hardness that density is large, wearability is good excessive, and the little poor shortcoming of material wear ability of hardness.Thereby comfortable and easy to wear, abrasion resistance is high and non-skid property good; Making step adopts Multi-layer design and takes the mode of Multi-step injection molding moulding, thereby can make multiple different colours in sandwich construction, so that exquisite appearance; Can offset making a concerted effort of foot and ground between the Multilayer Density material, thereby can reduce the sound of footwear and ground friction, and damping effect is arranged.

Fig. 3 is the cutaway view that shockproof top piece mould loam cake cooperates with bed die.
The specific embodiment
As shown in Figure 1, 2, the mfg. moulding die of shockproof top piece comprises the hollow pipe mould, wherein
On be covered with the material feeding groove, at the material feeding groove one material sputtering nozzle is arranged, in the other mould district that has some thickness not wait of material feeding groove, the mould district B that the mould district A that the degree of depth is darker and the degree of depth are more shallow has a plurality of pits in the mould district B, has passage to communicate with the mould district on the material feeding groove.
Bed die is provided with the material feeding groove, two mould districts that thickness does not wait, and the mould district B that the mould district A that the degree of depth is darker and the degree of depth are more shallow has a plurality of pits in the mould district A, a plurality of fore-sets is arranged in the mould district B and with the mould district of loam cake coupling and be used, have passage to communicate with the mould district on the material feeding groove.
