Abstract
The invention relates to a method for preventing products manufactured by a K204 mold from deforming. The method is characterized in that a nylon 6 is used as a raw material, an injection molding technology is adopted, the mold has three moldboards, the male mold serves as a slider, a moldboard has a cavity, and three-point needle point glue injection is carried out, wherein the male mold and a female mold are different in cooling temperature, and the temperature of the female mold is lower than that of the male mold. According to the method, the deformability of the products manufactured by the K204 mold is improved, and the molding cycle of the products does not need to be prolonged. The deformation of the products manufactured by the K204 mold is overcome by improving the temperature difference between the male mold and the female mold, and the production efficiency is ensured.
Description
Technical field
The present invention relates to product buckling deformation control mode method, especially a kind of method that prevents the deformation of products that the K204 mould is produced.
Background technology
The product that existing K204 mould is produced is take PA6(nylon 6) be to adopt injection mo(u)lding, shown in the finished product schematic diagram that Fig. 1 is the K204 mould by raw material.Working condition is: mould is that three template dies, sliding block of male die, a mould one cave, 3 pin marks advance glue, and PL is die joint; Forming bench 180T; Conventional moulding working condition; Feature die temperature during mould molding is between 40 ℃ ~ 60 ℃; Cooling water is naturally water, and water temperature is at 15 ~ 20 ℃.
Shown in the schematic cross-section and 24 hours schematic cross-section of Fig. 3 existing product cooling of depanning after the moulding of Fig. 2 existing product, under the natural state of cooling, buckling deformation appears in the face shaping of finished product after the moulding.By improving process conditions, as increasing dwell time or cool time, perhaps enter die improvement and all produce little effect, and increase the dwell time and the molding cycle of product is prolonged, production efficiency reduces greatly., adopt 3 pin marks to advance glue;
Therefore for above-mentioned technical problem, be necessary to provide a kind of new solution.
Summary of the invention
The object of the invention is to provide the method for the deformation of products that a kind of K204 of preventing mould produces, to overcome buckling deformation after the formed product cooling.
The present invention reaches goal of the invention by following technology: the method for the deformation of products that a kind of K204 of preventing mould is produced; take nylon 6 as raw material; adopt the injection molding process moulding; mould is that three plates, sliding block of male die, a mould one cave, 3 pin marks advance glue; wherein; the chilling temperature of male model and master mold is different, and the master mold temperature is lower than the male model temperature.Not only satisfy and improve the deformation of products that the K204 mould is produced, need not prolong the molding cycle of product simultaneously.
Principle is: when the die wall temperature contrast of feature die was little when the molding, the inside and outside surface temperature of finished product when the demoulding was almost identical; Add the characteristics of finished product outward appearance and the crystallinity characteristics of nylon 6, can't guarantee the balance of interiors of products and surface radiating; The impact of being heated and transmitting and expanding with heat and contract with cold has finally caused the tensile stress of finished product inside to strengthen, and causes the outward appearance buckling deformation of finished product, and by reducing the temperature of master mold, has guaranteed after the finished product demoulding heat dissipation balancing of finished surface in the natural cooling process.
On the such scheme basis, the deformation of products of producing in order further to improve the K204 mould, the cooling of male model environment for use water temperature, the mould temperature remains on 40-60 ℃; Master mold adopts the chilled water cooling that is lower than 11 ℃, and the forming temperature of master mold is down to about 35-40 ℃, and product qualified rate obviously improves.
On the such scheme basis, further, in view of the mould molding temperature of master mold can not be excessively low, for further strengthening the temperature difference of feature die, male model is used die heater instead and is supplied water, and by about 85 ℃ water temperature, makes the forming temperature of male model rise to 60-80 ℃, because the obvious temperature difference of feature die, cooling does not almost have buckling deformation after the finished product demoulding.
Superiority of the present invention is, by improving the temperature difference of male model and master mold, has overcome the deformation of products that the K204 mould is produced, and has guaranteed production efficiency.

The specific embodiment
Embodiment 1
A kind of method that prevents the deformation of products that the K204 mould is produced take nylon 6 as raw material, adopts the injection molding process moulding, and mould is that three plates, sliding block of male die, a mould one cave, 3 pin marks advance glue, and PL is die joint; Forming bench 180T; Press the moulding of PA6 injection mo(u)lding handbook standard normal condition, wherein, the chilling temperature of male model and master mold is different, and the master mold temperature is lower than the male model temperature, that is: male model environment for use water temperature cooling, and the mould temperature remains on 40-60 ℃; Master mold adopts the chilled water cooling that is lower than 11 ℃, and the forming temperature of master mold is down to about 35-40 ℃, and product qualified rate obviously improves.
Embodiment 2
Provide another kind to prevent the method for the deformation of products that the K204 mould is produced, working condition coexists mutually with embodiment 1 on above-described embodiment basis, further, in view of the mould molding temperature of master mold can not be excessively low, be the temperature difference that further strengthens feature die, male model is used die heater instead and is supplied water, water temperature by about 85 ℃, make the forming temperature of male model rise to 60-80 ℃, because the obvious temperature difference of feature die, cooling does not almost have buckling deformation after the finished product demoulding.
