Wherein, the outer side of each inner mold 20 of the microporous male mold 1 is sleeved with a metal outer liner 22, and the shape of the metal outer liner 22 corresponds to the shape of each inner mold 20. Therefore, air or moisture generated from the starchy material inside the mold during manufacturing can escape to the outside through the micropores of the microporous male mold 1 to release the pressure. Wherein the size of the micropores of the microporous male mold 1 is less than 0.3 mm.

A microporous master mold 3 includes a master mold body 30, wherein a plurality of mold cavities 40 are formed in the master mold body 30, and an opening 41 of each mold cavity 40 is located on an upper surface of the master mold body 30. The shape and size of each cavity 40 corresponds to the shape and size of the metal outer liner 22 of the microporous male mold 1. The microporous master mold 3 is mainly made of a material having micropores, such as a metal material, a ceramic material or a polymer material. Wherein the micropores of the microporous master mold 3 can penetrate through the inner wall of the mold cavity 40 and the exposed outer side of the microporous master mold 3 after molding. Therefore, air or moisture generated from the starchy material inside the microporous master model 3 during manufacturing can escape to the outside through the micropores of the microporous master model to release the pressure. Wherein the size of the micropores of the microporous master mold 3 is less than 0.3 mm.

As shown in fig. 1 and 5, each cavity 40 of the microporous master mold 3 is covered with a metal lining 42, and the shape of the metal lining 42 corresponds to the shape of each cavity 40. When the microporous male mold 1 is molded with the microporous female mold 3, the metal outer liner 22 of the microporous male mold 1 can be sleeved on the corresponding metal inner liner 42 of the microporous female mold 3, and the two are not in contact with each other, and a space 5 is formed therebetween, as shown in fig. 5. During the manufacturing process, starch material is injected into the space 5 between the mold cavity 40 and the inner mold 20, so that after the molding process of pressurizing and heating the microporous male mold 1 and the microporous female mold 3, the starch material is formed into the starch-based appliance 100 formed in the space 5, as shown in fig. 6.

The present invention further includes at least one female mold plate 50 having a plate-like shape, and a female mold through hole 51 is formed in the center of the female mold plate 50, the female mold through hole 51 having a shape corresponding to a mold cavity 40 of the microporous female mold 3. In which a screw hole 55 is formed to penetrate the female mold plate 50. And screw holes 45 corresponding to the screw holes 55 of the master mold plate 50 are formed around the opening 41 of the cavity 40 of the microporous master mold 3. When the female mold plate 50 is installed, the female mold plate 50 is placed on the upper surface of the microporous female mold 3, such that the female mold through hole 51 of the female mold plate 50 is aligned with the opening 41 of the mold cavity 40 on the upper surface of the microporous female mold 3, and the female mold plate 50 is positioned at the bottom outer side of the female mold through hole 51 and abuts against the upper end of the metal lining 42 inside the mold cavity 40, such that the metal lining 42 does not fall out. And the female mold plate 50 is screwed to the female mold body 30 by means of locking, as shown in fig. 4.

And screw holes 25 corresponding to the screw holes 65 of the male mold plate 60 are formed around the junction of the upper end of the inner mold 20 of the microporous male mold 1 and the upper plate 10, as shown in fig. 2. When the male mold plate 60 is installed, the male mold plate 60 is sleeved into the corresponding inner mold 20 of the microporous male mold 1, so that the upper surface of the male mold plate 60 contacts the lower surface of the upper plate 10, and the inner mold 20 is sleeved into the male mold through hole 61 in the center of the male mold plate 60. And the male mold plate 60 is screwed to the upper plate 10 by means of locking, as shown in fig. 3. Wherein each inner mold 20 is provided with a corresponding male mold plate 60.

As shown in fig. 5, during molding, the inner mold 20 of the microporous male mold 1 is nested into the corresponding mold cavity 40 of the microporous female mold 3, and the two are not in contact with each other, so as to form the space 5 therebetween. At this time, the male mold plate 60 of each of the microporous male molds 1 abuts against the female mold plate 50 of the corresponding microporous female mold 3.

As shown in fig. 1 and 5, at least one air channel 11 may be formed on the microporous male mold 1, wherein each air channel 11 penetrates through the upper surface of the microporous male mold 1 and a corresponding inner mold 20 and a corresponding metal outer liner 22. So that when demoulding, air can be injected into the air passage 11 to push against the already formed starch-based utensil 100 with the force of the air, so that the starch-based utensil 100 is separated from the metal outer lining 22 of the inner mould 20. The bottom of the air channel 11 may be formed with a plurality of small holes to prevent the starchy material from entering the air channel 11.

As shown in FIG. 5, the present invention can further form a plurality of through holes 31 in the metal lining 42 of the microporous master model 3 and the master model body 30. And the through hole 31 of the master model body 30 is made to communicate with the through hole 31 of the metal lining 42, and one side of the communicating through hole 31 is located on the inner wall of the metal lining 42 and the other side of the communicating through hole 31 is located on the outer side of the microporous master model 3 exposed after molding. So that gas generated from the starchy material during fabrication can escape outwardly through the through-hole 31.

Referring to fig. 7, in another embodiment of the present invention, an outer steel mold 70 may be wrapped around the outer sides of the microporous male mold 1 and the microporous female mold 3 to enhance the compactness of the microporous male mold 1 and the microporous female mold 3 after the molding. And a plurality of ventilation holes 75 may be formed in the outer steel mold 70 so that the gas generated inside can be discharged to the outside. Wherein the outer steel mold 70 is divided into an upper steel mold 71 and a lower steel mold 72. Wherein the upper steel die 71 has a configuration corresponding to the configuration of the outer side of the microporous male die 1. The lower steel mold 72 is formed in a pattern corresponding to the pattern of the outer side of the microporous master mold 3. The upper steel mold 71 and the lower steel mold 72 have corresponding air holes 75 formed therein. Therefore, after the microporous male mold 1 and the microporous female mold 3 are assembled, the upper steel mold 71 and the lower steel mold 72 are wrapped on the outer sides of the assembled microporous male mold 1 and the assembled microporous female mold 3.

During forming, the starchy material is placed in the space 5 and is subjected to high-pressure high-heat forming, and during actual operation, the starchy material mainly comprises a starch material, a foaming agent, a stabilizer, a fibrous reinforcing agent and filling powder, wherein the starch material is mainly potato starch, corn starch, cassava starch or other plant starch. Moisture must be added during forming to coagulate the materials. Then it is formed again at high heat during which the water evaporates, so that the microporous male mold 1 and the microporous female mold 3 help to remove the evaporated water. Further, the foaming agent may foam the formed starchy appliance 100 to reduce the material required.

When demolded, the exterior of the starchy appliance 100 may be coated directly with a release agent to facilitate demolding. And the interior is not suitable for spraying a release agent if food needs to be contained. The air channel 11 must be used to inflate and the force of the air pressure used to separate the mold from the starch-based appliance 100. Rough surfaces or grooves or granular protrusions may be formed on the inner mold 20 for gas-filled demolding.

The invention has the advantages that the female die combination plate is used for sealing and locking the metal lining at the inner side of the die cavity of the microporous female die, and when the metal lining needs to be replaced, only the individual female die combination plate needs to be detached. The whole operation is quite convenient. Moreover, the invention can achieve the purpose of rapid and simple demoulding by applying air channel inflation. The proper through holes are formed on the metal lining and the microporous master mold, so that vapor generated during forming can be effectively discharged. The mold design of the present invention does improve the disadvantages of the prior art and produces starchy appliances.

The above detailed description is specific to one possible embodiment of the present invention, but the embodiment is not intended to limit the scope of the claims of the present invention, and equivalent implementations or modifications without departing from the technical spirit of the present invention should be included in the scope of the claims of the present invention.
