By moving the inside of the first mold 10, it is possible to more completely seal the internal space between the skin 50 and the base member 12.
- a process of expanding the ash 50 may be further included (S40).
- the skin 50 clamped in the sealing state to the first mold 10 is sufficiently inflated by the air injected, the excessive amount of the skin material (particularly, the edge portion of the clamped skin material) 50 during the molding process. Whitening and eruption problems due to elongation can be prevented.
- air injection and suction may be simultaneously performed on the inner space between the skin 50 and the base member 12 (S44).
- the skin 50 By continuously circulating the internal air between the and the base member 12, the effect of cleaning the surface of the skin 50 and the base member 12 can also be expected.
- the air is ionized before being injected into the interior space between the skin 50 and the base member 12. It can also be configured.
- the vacuum hole 16 formed through the base member 12 to vacuum-adsorb the skin material 50 is a large diameter hole 17 for vacuum suction, and extends from the large diameter hole 17. It is made of a two-stage structure of the small diameter hole 18 in communication with the inner space between the ash 50 and the base member 12.
- the primary embossed transfer to the skin 50 is performed by combining the first mold 10 and the second mold. (S50).
- the second mold supports the skin material 50 so that the embossed transfer can be made more faithfully.
- first mold 10 and the second mold are formed a blank space at a predetermined interval for the base material is injected into the injection, so that even if the first mold 10 and the second mold are mutually matched, the second mold is a skin material There may be concern that one side of 50 cannot be contacted and supported.
- the thickness of the skin 50 is about 0.5t, so that a total space of 3t is formed between the first mold 10 and the second mold which are mutually joined.
- the thickness 0.5t of the skin material 50 corresponds to the thickness compressed during the molding process in the mold, and the actual skin material 50 thickness before applying pressure to the mold is typically 3t including the skin layer and the foam layer.
- the primary embossed transfer to the skin 50 may be performed as described above.
- the first mold 10 and the second mold are separated (S52), and an injection apparatus (not shown) is used.
- the substrate is injected into the second mold (S54).
- the separation of the first mold 10 and the second mold for the injection of the substrate is separated by a minute interval as long as the substrate can be introduced into the space between the first mold 10 and the second mold.
- This micro separation interval can be arbitrarily set according to the material and thickness of the skin material 50, preferably separated by about 5 ⁇ 30mm, which ensures the fluidity of the substrate and at the same time the skin material due to the high temperature and high pressure resin during injection This is to prevent the problem that 50 is destroyed.
- the first mold 10 and the second mold may be configured to inject the substrate into the second mold. At the same time as the separation, it may be configured to inject the substrate into the second mold.
- the second embossed transfer to the skin material 50 is performed (S56).
- the two-step embossing transfer process consisting of the primary and secondary processes, it is possible to more clearly and efficiently emboss the transfer to the skin material (50).
- the foam layer is made of an elastic material so that a cushioning feeling occurs.
- the restoring rate of the foam layer is inhibited by the strong pressure during the molding of the interior material.
- the cushioning of the foam layer does not occur and the quality may be degraded. Therefore, in order to prevent such a problem, by forming a pressure-reduction process in a state in which the first mold 10 and the second mold is not separated after the interior material molding is completed, it is possible to restore the recovery rate of the foam layer.
- FIG. 7 looks at the molding method of the horizontal movable vehicle interior according to a second embodiment of the present invention.
- the molding method of the vehicle interior material according to the second embodiment uses the molding apparatus of the second embodiment shown in FIG.
- the skin material 50 which is not preheated in advance is fixed to the transport means 70 by vacuum adsorption (S20), and the transport means 70 moves to the first mold 10 (S22). 50 is vacuum-adsorbed to the adsorption part 14 of the 1st mold 10 (S24). And in the state in which the skin material 50 is clamped to the first mold 10 by the fixing member 20 and sealed (S26), the skin material 50 through the heating unit 74 provided in the transfer means 70 ) Is preheated (S28).
- the skin 50 is measured by using a temperature sensor in the process of preheating through the heating unit 74 of the transfer means 70 (S30), the measurement
- the solenoid valve starts to vacuum in the internal air between the cuticle 50 and the base member 12 (S36).
- the sole valve is configured to be sucked only by the amount of the skin material 50 while being sequentially opened according to a predetermined speed, thereby solving the problem that the skin material 50 is struck by the load in the preheating process. Will be.
- the preheating time of the skin 50 is measured using a timer (S33), and the preheating of the skin 50
- the sole valve may be configured to be sucked only by the amount of the skin material 50 while being sequentially opened according to the preset speed (S36).
- the air injection into the inner space between the skin material 50 and the base member 12 to expand the skin material 50 (S40), the expanded When the skin 50 is supported by contacting the second mold, the skin 50 and the base member 12 are simultaneously carried out by performing air injection and suction on the inner space between the skin 50 and the base member 12.
- the step S50 of performing the first embossed transfer on the ash 50 is performed in the same manner as the forming method of the first embodiment (S26).
- a step of injecting the substrate into the second mold by separating the first mold 10 and the second mold (S54), the first mold 10 and the second mold Forming a second embossed transfer to the skin material 50 through a pressurizing and cooling process (S56), depressurizing the inside of the mold to improve the recovery rate of the skin material (S58), and
- S56 pressurizing and cooling process
- S58 depressurizing the inside of the mold to improve the recovery rate of the skin material
- S60 The process of extracting the interior material by releasing the clamping of the skin 50 and separating the first mold 10 and the second mold is also performed in the same manner as the molding method of the first embodiment described above.
- the present invention it is possible to integrally form the skin material and the base material in a mold operating in a horizontal manner, and also to prevent the phenomenon in which the skin material fabric stretched during the preheating process is struck down by the load, and also of the skin material. Perfect sealing prevents the skin from overlapping or crying.
- the embossing process for the skin material is configured in two steps, whereby the embossed pattern can be more clearly transferred to the surface of the skin material.
- the skin material does not fold or cry, and by injecting and circulating the ionized air can be expected to the cleaning effect on the skin material.
- the vacuum hole for the vacuum suction is configured in a two-stage structure, so that the vacuum suction is more smooth, and at the same time there is an effect such that the hole marks and the like remain on the surface of the skin during the vacuum suction process.
