[0044] like Figures 1 to 10 The present invention discloses a solid propellant rectangular test piece production device, comprising a pressing plate mechanism 1, a pressing plate ejection mechanism 2, a sub-component separation mechanism 3 and a test piece box separation mechanism 4, specifically as follows Figure 1As shown in , in an embodiment of the present invention, a pressing plate mechanism 1 is arranged above the medicine block mold, including a pressing plate 11 and a lifting assembly 12, and the lifting assembly 12 is connected to the pressing plate 11 for pressing the medicine block mold; in an embodiment of the present invention, the pressing plate assembly applies pressure to the medicine block mold after the casting is completed to ensure the stability during the medicine molding process. The pressing plate ejection mechanism 2 is arranged on the opposite sides of the medicine block mold, including a movable block 21 arranged opposite to the pressing plate 11 and an ejection drive 22 for driving the movable block 21 to rise and fall; after the medicine is formed, the pressing plate above the medicine block is automatically ejected by the pressing plate ejection mechanism 2. The sub-component splitting mechanism 3 is arranged on the other two sides of the medicine block mold, including a push plate 31 arranged toward the sub-component and a splitting drive 32 for pushing the push plate 31 to move toward the sub-component; the push of the push plate 31 on the sub-component separates the multiple sub-components, and the separated sub-components are in the form of test box boxes. The specimen box separation mechanism 4 includes a separation air claw 41 and a separation drive 42 connected to the separation air claw 41. The separation air claw 41 has a protruding claw 411 arranged corresponding to the groove on the specimen box, which is used to separate the specimen box from the specimen. The separation drive 42 in the specimen box separation mechanism 4 drives the separation air claw 41 to separate the half mold and the sub-component on the specimen box, thereby realizing the demoulding of the rectangular specimen.

[0045] In the above embodiment, by setting the pressing plate mechanism 1 and the pressing plate ejecting mechanism 2, the top plate pressing and automatic demolding of the top plate during the casting and molding of the rectangular specimen are realized, the multiple sub-components are separated by the sub-component splitting mechanism 3, and the specimen box separation mechanism 4 is set to achieve the detachment of the specimen box on a single sub-component. Compared with the prior art, the isolation of humans and drugs is achieved, and face-to-face operations during the demolding and shaping process are eliminated, thereby improving safety.

[0046] Alternatively, if Figure 2 As shown in , the lifting assembly 12 includes a nut seat 121 fixed on the frame and a lead screw 122 meshing with the nut seat 121. The pressing plate 11 is sleeved on the lead screw 122, and also includes a limit block 123 radially penetrating the lead screw 122; when the limit block 123 drives the lead screw 122 to rotate, it is pressed against the pressing plate 11 to achieve the compression of the top of the medicine block mold. When performing the specific operation, it is only necessary to rotate the limit block 123 to make the lead screw descend, and then the limit block 123 will press the pressing plate 11 downward. This method is simple to operate and easy to implement. The limit block 123 can be in the form of a bolt, or other forms of rods.

[0047] Alternatively, if Figure 2As shown in the figure, the clamping plate 11 includes a bottom clamp 111 and a top clamp 112 arranged parallel to the bottom clamp 111, and an elastic member 113 is arranged between the bottom clamp 111 and the top clamp 112. In the embodiment of the present invention, the bottom clamp 111 and the top clamp are both inserted into the lead screw 122, and the limit block 123 can be arranged between the bottom clamp 111 and the top clamp 112, or can be arranged on the top of the top clamp 112; the elastic member 113 here has various forms, for example, it can be Figure 2 The compression spring sleeved on the guide post shown in the figure may also be an elastic component such as rubber.

[0048] Alternatively, if Figure 3 As shown in , the ejection drive 22 includes a screw base 221, a motor screw 222 threadedly connected to the screw base 221, and a linear guide column 223 sleeved on the screw base 221, and the movable block 21 is fixed on the screw base 221. When ejecting, first remove the top pressure plate assembly, then remove the pull rod on the medicine block mold, so that the top plate is not bound; then drive the screw base 221 to rise through the rotation of the motor screw 222, and then drive the movable block 21 to move toward, the movable block 21 contacts the plate on the top of the medicine block mold, and under the continuous rotation of the motor screw 222, the plate on the top of the medicine block mold is separated from the sub-component. In addition, in an embodiment of the present invention, a linear bearing that cooperates with the linear guide column 223 can also be fixed on the screw base 221 to reduce the resistance of the screw base 221 to move. In an embodiment of the present invention, the linear guide column 223 adopts a hardened optical axis.

[0049] Alternatively, if Figure 4 As shown in , the movable block 21 has stepped surfaces with different heights, and the movable block 21 includes a base 211 connected to a screw base 221, two top columns 212 protruding from the top surface of the base 211, and a push surface 213 formed on the base 211 between the two top columns 212. Fig.10As shown in , in an embodiment of the present invention, the medicine block mold includes a bottom plate 01, an upper pressing plate 02, a medicine overflow plate 03, a short pull rod 04 for connecting the upper pressing plate 02 and the medicine overflow plate 03, and a long pull rod 05 for connecting the bottom plate 01 and the upper pressing plate 02. A slot for the top column 212 to pass through is provided on the upper pressing plate 02. When the movable block 21 rises, the two top columns 212 first pass through the slot on the upper pressing plate 02 and then abut against the medicine overflow plate 03; when the short pull rod 04 is removed, the separation of the medicine overflow plate 03 and the specimen box can be achieved by pushing the top column 212, and then the long pull rod 05 is removed, and the push surface 213 will contact the part between the two slots of the upper pressing plate 02, and then the push surface 213 of the movable block 21 will continue to push out the upper pressing plate 02 under the continued rotation of the motor screw 222. Through the setting of this structure, the medicine overflow plate 03 and the upper pressing plate 02 are ejected in sequence through a single action, which improves the convenience of operation.

[0050] Alternatively, if Figure 5 As shown in , the push plate 31 is arranged parallel to the arrangement direction of the sub-components and is arranged on both sides of the width direction of the sub-components, and one side of the push plate 31 has protrusions 311 arranged at intervals, the width of the protrusions 311 matches the thickness of a single sub-component, and is staggered with the protrusions 311 on the other push plate 31. In an embodiment of the present invention, the sub-components are placed in a medicine block mold in a single row, and when the pressure plate ejection mechanism 2 is used to eject the above-mentioned overflowing medicine plate 03 and the upper pressure plate 02, the specimen box of the sub-component will be exposed, but since there will be adhesion between the sub-components, the sub-components are separated by pushing the push plate 31 sideways. In an embodiment of the present invention, as Figure 5 As shown in , the width of the protrusion 311 of the push plate 31 is slightly smaller than the thickness of a single sub-component, and the distance between the two protrusions 311 is slightly larger than the thickness of a single sub-component, so that the push plates 31 on both sides push against each other, so that multiple sub-components can be disassembled at one time, thereby improving the efficiency of the separation process. In some embodiments of the present invention, a layout of 3+2 protrusions 311 can achieve the effect of separating five sub-components at one time.

[0051] Alternatively, if Figure 6 As shown in FIG. 1 , in order to avoid the risk of fire caused by hard contact between the steel component and the powder surface, in the embodiment of the present invention, an elastic body 312 is embedded on the surface of the protrusion 311 facing the sub-component, and the outer surface of the elastic body 312 protrudes from the surface of the protrusion 311 facing the sub-component. The elastic body 312 here has a variety of structural forms, which can be rectangular or can be as follows: Figure 6The horizontal cylindrical structure shown in the figure plays a buffering role in the splitting process through the setting of the elastic body 312, thereby improving the safety of the sub-component splitting process. In addition, in the embodiment of the present invention, a pressure sensor can also be set on the push plate 31 to detect the splitting force during the squeezing process. When the actual pressure is greater than the specified value, the pushing is stopped to ensure safety.

[0052] Alternatively, if Figure 7 As shown in , after the sub-components are separated, the specimen box on the sub-components needs to be demolded, and two separation air claws 41 are arranged opposite to each other, and the protruding claws 411 on the separation air claws 41 are arranged toward each other, and a clamping cylinder 43 connected to the two separation air claws 41 is also included, and the clamping cylinder 43 is used to drive the two separation air claws 41 to move closer or farther. Figure 8 As shown in , the test box is relatively close, and a groove is provided on the test box. By setting the protruding claw 411 on the separation claw 41, the protruding claw 411 can be embedded in the groove of the test box, and then the separation of the test box from the sub-component is achieved by pulling the separation drive 42. In the embodiment of the present invention, the drive can be a cylinder, and by setting the stroke of the separation cylinder, the separation claw 41 reaches the groove on the side wall of the test box, and then the clamping cylinder 43 is tightened to keep the protruding claw 411 in the groove, and then the separation drive 42 pulls the separation claw 41 back to make the half mold of the test box fall off, and the other side can be carried out synchronously.

[0053] Optionally, in order to ensure the reliability of demoulding of the specimen box, Fig. 9 As shown in FIG, the specimen box separation mechanism 4 further includes a locking assembly 44, which includes a stopper 441, a sliding block 442 and a toggle clamp 443. For details, please refer to Fig. 9 The stopper 441 is arranged on one side of the specimen box in the width direction and abuts against the side wall of the sub-component; the sliding block 442 is arranged on the other side of the specimen box in the width direction and can be moved toward or away from the specimen box to press the sub-component; the elbow clamp 443 is connected to the sliding block 442. When the elbow clamp 443 is locked, the sliding block 442 is pressed against the side wall of the sub-component. When placing the specimen box, first abut one end of the specimen box against the stopper 441, then push the elbow clamp 443 so that the sliding block 442 contacts the specimen at the center of the specimen box. It should be pointed out here that if Fig. 9 As shown in , the specimen box also has a window for the sliding block 442 to penetrate, through which the sliding block 442 abuts against the specimen, and the window is formed by the two half molds of the specimen box, so when the half molds are separated, it does not affect the fixing of the specimen by the locking assembly; in addition, in the embodiment of the present invention, the locking assembly 44 also includes a slide rail 444, and the sliding block 442 can be relatively slidably connected to the slide rail 444. Specifically, as shown in Fig. 9As shown in , in some embodiments of the present invention, the slide rail 444 can be fixed to the bottom of the bracket through a fixing groove, and then a hole is opened on the bracket so that the sliding block 442 protrudes above the bracket to fix the position of the sub-component.

[0054] Application scenario of an exemplary embodiment:

[0055] like Figures 1 to 10 When producing rectangular specimens, first, the test kits are placed side by side into the medicine block mold, and then the upper pressing plate 02 and the overflowing medicine plate 03 are covered, and they are connected and fixed by the long pull rod 05 and the short pull rod 04, and then the pressing plate assembly is used to achieve compression. After molding, the pressing plate assembly is removed; and the long pull rod 05 and the short pull rod 04 are removed, and then the pressing plate ejection mechanism 2 is actuated to eject the upper pressing plate 02 and the overflowing medicine plate 03; then the push plate 31 on the sub-component separation mechanism 3 is used to push the multiple sub-components adhered together in opposite directions to achieve separation, and then the separated sub-components are fixed on the locking mechanism, and the protruding claws 411 on the separation claws 41 are engaged with the half molds on the specimen box by the clamping cylinder 43, and then the two half molds on the specimen are separated by pulling outwards. Through the above process, the separation of human and medicine during the demolding process of the rectangular specimen is achieved, and manual face-to-face violent operations are avoided, thereby improving the efficiency and safety of specimen demolding.
