     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Please refer to following example together with drawings for the structure and functions of present invention: 
     As shown by FIG.  1  and FIG. 2, the present invention of a plate type of continuous injection mold machine consists of conveyance pipe  11 , pump  12 , inlet pipe  13 , injection device  14 , first mechanical plate  20 , second mechanical plate  21 . Open-plate and plate control device  22 , joint bar  23 , two tracks  24 , two side frames  25 , conveyance belt  26 , active mechanical plate  27  and several forming plates  3 . 
     Regarding the process of inlet of material, there is a pump  12  connecting the rear end of conveyance pipe  11 . The pump  12  connects an inlet pipe  13 . The inlet pipe  13  is a T-shaped pipe, one end connects the injection device  14 , the opposite end connects the material inlet  201  on first mechanical plate  20 , while the top end connects another pump  12  for continuous supply of material. Please refer to FIG. 3, a valve  15  may be installed on the joint of the inlet pipe  13  and pump  12 . This valve  15  allows inlet of material and restricts outlet of material. Once conveyed into the inlet pipe  13  via pump  12 , the pulp  9  cannot return to the pump  12  any longer (as shown by FIG.  4 ). Due to the function of injection device  14  in the inlet pipe  13 , the pulp  9  being transmitted to inlet pipe  13  will be conveyed to the material inlet  201  (as shown by FIG. 5) by the injection device  14 . The injection device  14  can be either an air-pressured cylinder that consists of a piston  16  on its joint protracting into the inlet pipe  13 . 
     The first mechanical plate  20 , second mechanical plate  21 , active mechanical plate  27  and all forming plates  3  are aligned parallel to one another. The first mechanical plate  20  and second mechanical plate  21  are fixed on two corresponding side frames  25 . The outer end of second mechanical plate  21  connects to an open-plate and plate control device  22 . The joint bar  23  of the open-plate and plate control device  22  protracts through the center of second mechanical plate  21  and connects the active mechanical plate  27 . In other words, when the open-plate and plate control device  22  drives the joint bar  23  to expand and contract, the active mechanical plate  27  moves its position accordingly. There are several forming plates  3  between the active mechanical plate  27  and first mechanical plate  20 . Chains  31  are installed between all forming plates  3  to facilitate the joint movement of all forming plates  3 . 
     Two tracks  24  are installed horizontally on both sides between first mechanical plate  20  and second mechanical plate  21 . In other words, all forming plates  3  are installed in the area surrounded by two tracks  24 , first mechanical plate  20  and second mechanical plate  21 . All forming plates  3  moves along two tracks  24 . This is how it works. Upper-knuckle stand  32  and lower-knuckle stand  33  are installed on both sides of each forming plates  3 . The inner surface of upper-knuckle stand  32  and lower-knuckle stand  33  is equipped with arc-shaped washer or bronze ring  321 ,  331  to match track  24  and facilitate rolling on the track  24 . A fastener  34  is installed on the end of upper-knuckle stand. This fastener coordinates the knuckle movement of upper-knuckle stand  32  and lower-knuckle stand  33 . The lower-knuckle stand  33  is active and capable of swaying ninety degrees below. All forming plates  3  move as the upper-knuckle stand  32  and lower-knuckle stand  33  move along the track  24 . As the lower-knuckle stand can sways below, the forming plate  3  can be placed on the track  24  or removed. 
     As shown by FIG. 6, there is an injection inlet  360  on the center of forming plate  3 . In this example, each piece of forming plate  3  consists of four molds  35 . Convex and concave are distributed on the surface of molds  35 . Each mold  35  incorporates with a mold plate  39 . There is a space between mold plate  39  and mold  35 . This space accommodates the pulp  9 . The mold plate  39  is assembled on the forming plate  3  and is blocked by several blocking plates  38 . There is a gutter  361  between injection inlet  360  and mold  35 . There is a drainage pipe  370  on the edge of all molds  35  connecting a spillover outlet  371 . 
     As the forming plates  3  are adjacent to one another, the injection inlets  360  of all forming plates  3  connect to one another and the material inlet  201 . Once entering into the material inlet  201 , the pulp  9  will continue entering into the injection inlets  360  of each forming plate  3 , then entering into the space between all molds  35  and mold plates  39  via gutter  361 . As pump  12  continues injecting pulp  9  into the machine, the pulp  9  located in the space between molds  35  and mold plates  39  is pressed tighter and tighter, and dehydrated gradually, eventually the small-sized finished products  4  shown by FIG. 7 are produced. To pick up the small-sized finished products  4 , the open-plate and plate control device  22  drives the joint bar  23  to contract outward in order to activate the active mechanical plate  27  to separate all forming plates  3  by chains  31 , then pick up the small-sized finished products  4 . 
     To ensure that the pulp  9  completely fills the mold, the present invention includes drainage pipe  370  and spillover outlet  371 . As soon as the mold  35  and mold plate  39  is full of pulp  9 , the extra pulp  9  will be discharged. Without the drainage pipe  370  and spillover outlet  371 , the pulp  9  would not completely fill the mold  35  and mold plate  39 . 
     FIG. 6 shows an example of producing four pieces of small-sized finished products  4  by a forming plate  3 . To product a large-sized finished product  6  by a forming plate  3 , please refer to FIG.  9 . Same molds  51  are installed on the forming plate  5  with an additional mold plate  52 . The mold plate  52  is fixed by several blocking plates  53 , too. The pulp  9  is conveyed via the injection inlets  54  and gutter  541  on four corners. The large-sized finished products  6  are shown by FIG.  9 . 
     The present invention is capable of producing large-sized finished products  6  and small-sized finished products  4  simultaneously. Overlap the forming plate  5  and forming plate  3  together as shown by FIG. 10, the pulp  9  enters into through the injection inlet  360  of forming plate  3 , runs through gutter  361  to the molds  35 , then runs through the drainage pipe  370  and spillover outlet  371  to the injection inlets  54  on four corners of a forming plate  5  in the rear, and then flow into the mold  51  via gutter  541 . 
     FIG. 11 shows that the finished products manufactured by present invention can be either picked up by robotic arm  7  or conveyed by the conveyance belt  26  on the bottom. 
     FIG.  12  and FIG. 13 indicate that the forming plates  3 , 5  can be made in the shape based on actual needs. Naturally, the quantity and size can be decided according to actual needs as well. 
     Based on the preceding statement, the present invention of “a plate type of continuous injection mold machine” manufacturers products by injecting and pressing the pulp material in the molds. This method has a number of advantages. The present invention&#39;s nature of progress and usefulness is obvious and has never been disclosed in any patent bulletins before.
