The second mold portion 2 1 2 is maintained at a position of about 20 to 60 seconds, so that the moldable compound 2 1 6 is rapidly formed. The heat in the first mold part 2 10 and the first mold part 212 expands due to the expansion of the moldable compound 2 1 6, which causes the moisture in the moldable compound 2 16 to evaporate. 'And the pressure provided to the moldable compound 2 1 6 and the expansion of the moldable compound 2 丨 6 fill the mold recess 2 1 1 between the first mold portion 2 1 0 and the second mold portion 2 1 2 Void. Moisture in the form of water vapor is released through a predetermined gap between the first mold part 2 10 and the second mold part 2 12. • When the temperature of moldable compound 2 1 6 increases, the adhesive in moldable compound 2 i 6 starts to form and increases the viscosity of moldable compound 21 6. m; Kang t issued? An embodiment is used to illustrate an enlarged schematic view of one of the second mold portions 212 during the formation of the mold product: 4 L Λ.

Page 32 200540070 V. Description of the invention (27) Heat conduction from 2 1 0 and the second mold part 2 1 2 to the moldable compound 2 1 6. § When the moldable compound 2 16 is expanded, the vent holes 21 8 are blocked to prevent the release of water vapor. Therefore, when the moisture in the moldable compound 21-6 evaporates instead of escaping, the pressure in the moldable compound 2 1 6 increases. The trapped water vapor constitutes a plurality of vapor pockets (poc k e t s) 2 2 4 in the moldable compound 216, and the porous structure 2 2 6 is precipitated within the moldable compound 21 6. In order to avoid the loss of heat due to the escape of water vapor from the moldable compound 2 16 due to the increase in the temperature of the moldable compound 21 6.尺寸 The size of the plurality of steam pockets 2 2 4 increases with the temperature of the moldable compound 2 1 6. When the first mold part 2 10 and the second mold part 2 1 2 are maintained below 9 π, 'will reduce the amount of moisture evaporation and form a small amount of vapor outer bag. The same product of L ^ ^ produces mold products with relatively high demand. Conversely, the second mold portion 210 and the second mold portion 212 produced at a higher temperature will result in a molded product having a lower degree of quality. For each mold sold, the first mold section 21 and the second mold section 212 also reduce the production time of the person. However, if the temperature is not higher than about 18 ° C., “The high temperature of the two courts will burn the moisture in the mold compound 216 in the moldable compound 2 丨 6, resulting in the formation of =

Page 33 200540070 V. Description of the invention (28) Therefore, the system of the first mold part 2 1 0 and the second tungsten mold part is maintained in the range of about 1 10 to 18 0 ° C. The mold part 2 1 0 and When the temperature of the second mold part 2 1 2 is within the range of 2 °, the temperature of the moldable compound 2 1 6 is between a wide range. Control the heat in moldable compound 2 1_ Moisture evaporation in mold compound 2 1 6 to ensure that the majority of vapor outer bags 2 2 4 are evenly distributed to form a phase with aa ° The pressure in moldable compound 216 exceeds the outside The occlusion will break and exceed the water vapor in the moldable compound 2 1 6 and the vapor that escapes from the adhesive hole 2 1 8 will reduce the moldable compound to calculate the void C during the molding process and release it. The pressure of water is sufficient to fill the space in the first mold part 2 1 0 and the mold recess 2 1 1 therebetween. Adjusting the gap C between the first two mold parts 2 1 2, that is, ϋ t, can control the pressure of the moldable compound 2 1 6 and the excess of moldable compound 21 6 t, for example, a larger gap C escapes due to the presence of lower pressure vapors and transferable compounds. Conversely, a temperature of 2 1 2 is better. Experiments show that when the distribution of the first change in the above range of about 100 to 160 ° C can control the productivity of the mold with the same density in the porous structure 2 2 6, the ventilation hole 2 1 8 mold compound 2 1 6, can be formed to the pressure through the ventilation 216. Vapor while maintaining the temperature and discharge volume of the second mold part 2 1 2 and the mold part 2 1 0 and the I air hole 2 1 8. Force to make more water, the gap C restricts water

Vapor is released and contains water vapor expansion, resulting in a molded product with a lower density. However, 'when the moldable compound 216 cannot close (0 ^ 111 &) the vent hole 2 1 8', it does not require a large gap c. Therefore, there will be no pressure in the gap c, and the moldable compound will not fill the light mold recess 2 1 1 between the first mold part 2 and the first mold part 2 1 2. When the above situation occurs, the ballast product will not be the desired shape. The size of the gap C is also determined by the thirst content in the moldable compounds 2 丨 6. -When the moldable compound 216 contains less moisture, the better system uses a smaller gap c; while in the above form, when the moldable compound 216 contains more moisture, the 'better system uses more Large gaps C, but emit more gas. When the moldable compound 21 6 is roughly formed to form a mold product, it is preferable that approximately 90% is formed. The moisture content of the molded product is preferably in the range of about 2 to 5%. The piston 2 06 is then increased with a gap c of about 10 to release all the unused water vapor discharged during the casting process. If the moldable compound 2 1 6 is rapidly formed to increase the gap c, it is not suitable to remove the wet + air volume from the = mold compound 2 丨 6, and the mold product will become ~ soft and have an adhesive mold recess 2 1 1 toilet also participates Yu, Rendang 9] 0

200540070 V. Description of the invention (30) (distort) the outer surface layer 220 and damage the porous structure 226. Therefore, the removal of moisture from the moldable compound 2 1 6 is extremely important to achieve a mold product with sufficient strength to withstand pressure and strain during processing and handling. After releasing unused vapors , The gap C is reduced to a range of about 0.05 to 0.3 mm and maintained in a range of about 15 to 60 seconds, to compress the mold product to a desired thickness, and to iron the mold product The surface gives it a good surface texture. Furthermore, in order to make a stable mold product, moisture will evaporate. Thereafter, the piston 20 is moved to pull the mold piston 2 丨 3 away from the mold recess 2 1 1, and the mold product is removed for subsequent procedures. Mould products can be removed from the mould cavity = 2 1 1 using pick and place machines. Λ, the mold recess 211 is preferred. When the gap c is increased to about 10 mm to release the air, the use of an injection molding machine to provide a mold product from the mold recess 211, and It also helps mold products out of the mold. Figure 1A and Figure 9B are schematic diagrams illustrating a cross section of a device 2 34 according to an embodiment of the present invention. Figure 9 illustrates the “injection <” ^ time, and Figure 9B illustrates the operation of an injection molding machine.

200540070 V. Schematic diagram of invention description (31). Referring first to FIG. 9A, the injection molding machine 234 is housed in a recess 2 3 4 of a housed mold, and is located under a mold product 2 3 6. The injection molding 234 includes a head 2 3 8 which is coupled to a 2 3 6 base 2 4 0 through a shaft 242 (shaft) and a spring 2 4 4 surrounding the shaft 2 4 2. At rest, the springs 2 4 4 are uncompressed. In the above embodiment, the injection molding 2 34 is operated by a pneumatic system (not shown). The handle 24 2 provides an O-ring 246 (Q-ring. To avoid the loss of air from the gas-filled system. In another embodiment, the injection molding 2 3 4 can be operated by a hydraulic ic system. When the gap C is increased or when the mold product 2 3 6 is removed from the mold recess 2 1 1, the pneumatic system is moved and a force is exerted on the substrate 2 4 0, and the spray is driven in the X axis direction. Out of the machine 2 3 4 and in the process press-shrink the spring 2 4 4 as described in Figure 9B. Therefore, lift the mold product 2 3 6 from the mold recess 2 1 1. Out of the mold · 2 3 4 by withdrawal The pneumatic system returns to the rest position, as described in Figure 9A. The expansion of the spring 244 will apply a force to the base 2 4 0 'to drive the injection molding machine in the opposite direction of the X axis 2 3 4 'until it reaches a stationary position.

200540070 V. Description of the invention (32) Pneumatic or hydraulic systems can be operated with the same limit switch. The above limit-open relationship is used to reduce the speed at which the recording piston 2 1 3 approaches the mold recess 2 1 1. Referring again to FIG. 8, since the adhesive and fiber mixture may absorb too much heat and burn, the moldable compound 21 6 should not be left in the mold recess 2 1 1 for an extended period of time. If the moldable compound 2 1 6 stays in the mold recess 2 1 1 for a long time and loses a lot of moisture, cracks and deformation may occur. The degree to which the mold recess 21 1 is covered will affect the density of the mold product. If the mold product 2 1 6 is insufficiently loaded in the mold recess 2 1 1, the mold product 2 1 6 will not be able to fill the mold recess 2 1 0 between the first mold part 2 1 0 and the second mold part 2 1 2 1. In the above case, when the mold product 2 1 6 is insufficiently loaded in the mold recess 2 1 1, a dense mold product having a high moisture content is formed. Fig. 10 illustrates a method 250 for forming a mold product according to another embodiment of the present invention.
