Abstract
The utility model discloses a foaming forming mold. The foaming forming mold comprises a concave mold and a convex mold. The concave mold is composed of a concave mold core, a concave mold core mounting plate and a concave mold rear panel. A concave mold titanium metal layer is arranged on the inner surface of the concave mold core in a coating mode. The convex mold is composed of a convex mold core, a convex mold core mounting plate and a convex mold rear panel. A convex mold titanium metal layer is arranged on the inner surface of the convex mold core in a coating mode. The inner surface of the concave mold core of the foaming forming mold and the inner surface of the convex mold core of the foaming forming mold are both provided with the titanium metal layers in a coating mode, so that surface rigidity of mold cores is enhanced, and the mold cores are wear-resistant, not easy to deform and long in service life.
Description
Technical field
The utility model belongs to the injection molding technology field, is specifically related to a kind of foaming molding mold.
Background technology
Foaming molding mold (foaming mould) claim again plastic foaming mould, its foaming principle is: directly insert the foaminess resin in the mould cavity, in the vaporium of die cavity outside, be filled with high-temperature steam, make the foaminess resin melted by heating in the die cavity, form the gas-liquid saturated solution, by nucleation, form a large amount of small complexs, complex increases, and makes the foam plastic.
Foaming molding mold comprises die and punch, and during shaping foam, die and punch combine.Die core and punch core are entrenched togather mutually, form the forming cavity of hollow, thermoplastic expanded plastic pellet according to certain track, certain flow, be injected in the die cavity certain duration of pouring and control the temperature of temperature, mould of raw material and pressure during cast, pressurize a period of time aftershaping.
Die sinking after the moulding; the die of mould separates with punch; craft or utilize manipulator that the foamed plastic part of moulding is taken off on mould; and when taking off product, can produce friction between product and the mold former, after causing that foaming molding mold is long-time and using; it is large that the forming cavity inner space of die core and the chimeric one-tenth of punch core becomes; cause the product size behind the foaming defective, need repair a die or again open new mould, serious waste of resources.
Summary of the invention
The utility model purpose provides a kind of foaming molding mold, by the improvement of structure, and mold cores case hardness enhancing, wear-resistant, and core is not yielding, long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of foaming molding mold, comprise die and punch, described punch and matrix is made of core, core installing plate and backboard separately, and the inner surface of described die core is covered with the die titanium coating.
In the technique scheme, the outer surface of described punch core is covered with the punch titanium coating.By said structure, mold cores case hardness enhancing, wear-resistant, and core is not yielding, long service life.
Preferably, the thickness of described die titanium coating is 0.05～0.2mm.The thickness of described punch titanium coating is 0.05～0.2mm.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. die core inner surface of the present utility model and convex model core outer surface all are covered with titanium coating, the case hardness enhancing of mold cores, wear-resistant, and core is not yielding, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one;
Wherein: 1, die core; 2, die core installing plate; 3, die backboard; 4, die titanium coating; 5, punch core; 6, punch core installing plate; 7, punch backboard; 8, punch titanium coating.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: referring to shown in Figure 1, a kind of foaming molding mold, comprise die and punch, described die is made of die core 1, die core installing plate 2 and die backboard 3, and the inner surface of described die core 1 is covered with the die titanium coating 4 that thickness is 0.06mm.
Described punch is made of punch core 5, punch core installing plate 6 and punch backboard 7, and the outer surface of described punch core 5 is covered with the punch titanium coating 8 that thickness is 0.06mm.
Die core inner surface and the convex model core outer surface of present embodiment all are covered with titanium coating, the case hardness enhancing of mold cores, wear-resistant, and core is not yielding, long service life.
