As shown in fig. 1 and 3-5, threaded holes 5 are formed around the bottom surface of an upper half forming die 401, a threaded column 6 is connected inside the threaded hole 5, the bottom of the threaded column 6 is rotatably connected with an electric lifting rod 7, the outside of the electric lifting rod 7 is connected with a lower half forming die 8, the lower half forming die 8 is connected with the upper half forming die 401 in a lifting mode through the electric lifting rod 7, the lower half forming die 8 is in threaded connection with the upper half forming die 401 through the threaded column 6 and the threaded hole 5, a plate frame forming groove 9 is formed in the top surface of the lower half forming die 8, vent holes 10 are formed in the bottom of the inner wall of the plate frame forming groove 9 in an array mode, vent columns 11 are arranged inside the vent holes 10, and the bottom of the vent columns 11 is connected with an adherent rubber ring 12.
The specific operation is as follows, the lower half forming die 8 enters the forming cavity 2 along with the upper half forming die 401 synchronously, at the moment, the electric lifting rod 7 keeps the extending state to form a gap between the lower half forming die 8 and the upper half forming die 401, the liquid raw material enters the plate frame forming groove 9 along with the gap and fills up the gap, then the electric lifting rod 7 contracts to ensure that the top of the lower half forming die 8 is jointed with the bottom of the upper half forming die 401, the inner space of the plate frame forming groove 9 is closed, the redundant liquid raw material is discharged back to the forming cavity 2, the liquid raw material is arranged in the plate frame forming groove 9 and is solidified and formed under the action of the ventilating column 11 to form a plate frame with hole positions, the distance between the outer wall of the lower half forming die 8 and the inner wall of the forming cavity 2 after rising is the same as the distance between the upper half forming die 401 and the forming cavity 2, the thickness of the formed box body is uniform, and after the plate frame and the box body are formed, the mold cover 3 is taken down, the lower half forming mold 8 and the upper half forming mold 401 are spaced, the threaded column 6 is rotated at the moment, the threaded column is connected with the threaded hole 5 in a threaded mode, so that the threaded column and the upper half forming mold 8 are separated, the lower half forming mold 8 and the upper half forming mold 401 can be separated, meanwhile, the vent column 11 is separated from the inside of the vent hole 10, and the plate frame can be taken down at the moment.
As shown in fig. 1 and 5, second air holes 13 are uniformly formed in the outer peripheral surface of the lower half forming die 8, and a second waterproof and breathable film 14 is attached to the outer surface of the lower half forming die 8;
the concrete operation is as follows, whether the lower half forming die 8 is lifted and is ventilated the post 11 and is located inside the air vent 10 all the time and fill up the gap between the two through the adherent rubber ring 12 for the vacuum pump 405 also can realize defoaming operation in the peripheral area of the lower half forming die 8 through the second air hole 13, the waterproof ventilated membrane 14 of second when the operation, thereby improve defoaming efficiency.
As shown in fig. 1 and 4, the top of the vent column 11 is fixedly connected with the bottom of the upper half forming die 401, the upper half forming die 401 is communicated with the lower half forming die 8 through the vent column 11 and the vent hole 10, and the outer wall of the wall-attached rubber ring 12 is attached to the inner wall of the vent hole 10;
the clearance between 11 and the air vent 10 of ventilating post is filled to adherent rubber ring 12 for the gas tightness can be strengthened, thereby realizes half moulded die 401 and the intercommunication of half moulded die 8 down, makes things convenient for both to carry out the defoaming operation to its peripheral region, and the inside grillage shaping back of making grillage shaping hole site that forms of ventilating post 11 passes grillage shaping groove 9 in addition naturally.
In conclusion, the medical shell has a forming device with a bubble removing function, when in use, firstly, the mold cover 3 is tightly connected with the lower mold 1 through the bolt, so that a closed space is formed inside the forming cavity 2, at this time, the liquid raw material is already inside the forming cavity 2, then the vacuum pump 405 operates to pump out air inside the forming cavity 2, the air sequentially passes through the first waterproof breathable film 403 and the first air hole 402 and is discharged from the exhaust end of the vacuum pump 405, so that the inside of the forming cavity 2 is vacuumized, at this time, the air in the liquid raw material is also pumped out to realize vacuum defoaming, and the air pressure condition inside the forming cavity 2 can be known in real time through the air pressure instrument 404, so that the air pressure inside the forming cavity 2 can be controlled conveniently;
then, after the liquid raw material in the molding cavity 2 is defoamed, the volume of the liquid raw material is slightly reduced due to the disappearance of gas, and since a part of redundant liquid raw material is stored in the liquid storage tank 1501, the redundant liquid raw material can be pushed into the molding cavity 2 for supplementation by pushing the liquid pushing head 1504 through the electric push rod 1503, so that the molded box body keeps the standard specification;
because the lower half forming die 8 enters the forming cavity 2 along with the upper half forming die 401 synchronously, the electric lifting rod 7 keeps an extending state to enable a gap to be formed between the lower half forming die 8 and the upper half forming die 401, the liquid raw material enters the plate frame forming groove 9 along with the gap and fills the gap, then the electric lifting rod 7 contracts to enable the top of the lower half forming die 8 to be attached to the bottom of the upper half forming die 401, the inner space of the plate frame forming groove 9 is closed, the redundant liquid raw material is discharged back to the forming cavity 2, the liquid raw material is arranged in the plate frame forming groove 9 and is cured and formed under the action of the ventilating column 11 to form a plate frame with hole positions, and the distance between the outer wall of the lower half forming die 8 and the inner wall of the forming cavity 2 after rising is the same as the distance between the upper half forming die 401 and the forming cavity 2, so that the thickness of the formed box body is uniform;
after the box body and the plate frame are molded, the die cover 3 is taken down, the lower half molding die 8 and the upper half molding die 401 are separated, the threaded column 6 is rotated to be connected with the threaded hole 5 through threads, so that the lower half molding die 8 and the upper half molding die 401 are separated, meanwhile, the vent column 11 is separated from the inside of the vent hole 10, and the plate frame can be taken down;
most probably because electric putter 1503 promotes liquid pushing head 1504 can push surplus liquid raw materials into the inside as the replenishment of molding chamber 2, until molding chamber 2 is inside to be full of liquid raw materials, show that liquid pushing head 1504 can't promote the inside liquid raw materials of reservoir 1501, and the inside remaining liquid raw materials of reservoir 1501 forms the cylinder after the box body solidification shaping, and because the effect of annular lead-through core 1502 makes the cylinder surface far less than the diameter of other positions rather than the diameter of the position of coincidence, this position of cylinder breaks under the atress effect when taking out the box body again this moment, thereby avoid the box body surface to have surplus component, and because annular lead-through core 1502 and reservoir 1501 plug-in connection, can take out it through using the couple hook annular lead-through core 1502, thereby conveniently clear up the inside cylinder of reservoir 1501.
