Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a forming platform mechanism and three-dimensional forming equipment. Background Art

[0002] In the photocuring stereo molding equipment, the molding platform moves toward the material trough under the drive of the power mechanism. When the molding platform and the release film are separated by a layer of model thickness, the driving light source emits a curing light that matches the contour of the single-layer model, so that the resin between the molding platform and the release film is cured, forming the first layer of the model and adhering to the molding platform. Then the molding platform drives the molded model to rise, the resin refluxes, and repeated exposure is achieved to achieve layer-by-layer superposition.

[0003] In order to prevent the model from falling off the forming platform, the first layer of the model has a strong adhesion to the forming platform. After printing, it is necessary to use a tool such as a spatula to scrape the model off. It is difficult to pick up the model and it is easy to scratch the model. In the existing technical solution, there is a spring steel plate as the model contact plate of the forming platform, and the spring steel plate is fixed by magnetic attraction. For example, in the patent with publication number CN219276676U, the printing platform includes a base, the base is magnetic, the spring sheet is magnetically attracted to the base, and the bottom surface of the spring sheet is the forming surface. However, the magnetic attraction method is difficult to take into account both the adsorption strength and the convenience of disassembly. If the adsorption strength is strong, it is difficult to disassemble. If the adsorption strength is weak, there is a risk of the spring steel plate and the model thereon falling off together.

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the present invention, the specific implementation method, structure, characteristics and effects of the molding platform mechanism proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] On the one hand, if Figure 1-2 As shown, the embodiment of the utility model provides a molding platform mechanism for a three-dimensional molding device, the three-dimensional molding device includes a device body, and the molding platform mechanism includes:

[0026] The main body 100 includes a supporting assembly 110 and a fixing assembly movably connected to the supporting assembly 110, the supporting assembly 110 is used to be directly or indirectly connected to the device main body, and the fixing assembly includes an upper hanging portion 161;

[0027] The easily detachable platform assembly 200 includes a model plate 210 and a plurality of lower hanging parts 220 for connecting with the upper hanging parts 161. The model plate 210 is used to deform under the action of external force, and the lower hanging parts 220 are connected with the model plate 210;

[0028] The fixing assembly is used to fix the model plate 210 on the supporting assembly 110 .

[0029] The main body of the three-dimensional molding equipment mainly includes a lifting mechanism, a cantilever, a base and a material trough. The lifting mechanism is connected to the base, the cantilever is connected to the lifting mechanism, and the material trough is used to be placed on the base. The molding platform mechanism is connected to the cantilever. The lifting mechanism is used to drive the cantilever to rise and fall, and then drive the molding platform mechanism to rise and fall in the direction close to or away from the material trough to achieve three-dimensional molding.

[0030] In the molding platform mechanism, the support assembly 110 is used to connect with the cantilever, and the connection method can be various, such as the support assembly 110 may include a connection block with an embedding port, the connection block is sleeved on the cantilever, a screw hole is set on the cantilever, and one end of the plum blossom handle 300 is a stud, the stud passes through the connection block, and is screwed into the screw hole to squeeze and fix the connection block, thereby achieving the fixation of the relative position of the main body 100 and the cantilever. For the convenience of explanation, the following embodiments are all taken as an example of the direction when the molding platform mechanism is actually used.

[0031] The model plate 210 is elastic and can be bent under the action of external force, while the model bonded to the model plate 210 is solid, and the model is less bendable than the model plate 210. When the model plate 210 is bent to a certain extent, the model will be separated from the model plate 210, and then the model can be removed without the help of external objects such as a knife or a shovel. The model plate 210 can be made of a variety of materials, such as a SUS301-SEH stainless steel plate, or other spring steel plates. The bottom surface of the model plate 210 can be a smooth surface, a laser-engraved surface, or a frosted surface, which can be selected according to factors such as the material of the resin and the overall weight of the model.

[0032] The model plate 210 is located below the supporting assembly 110 , and the upper hanging parts 161 correspond to the lower hanging parts 220 . Specifically, the number of the upper hanging parts 161 corresponds to the number of the lower hanging parts 220 .

[0033] In one embodiment, the fixing assembly includes a pull frame assembly 120 and a pull rod 160 . The pull frame assembly 120 is movably connected to the support assembly 110 . The pull frame assembly 120 is fixedly connected to the pull rod 160 . The upper hanging portion 161 is provided on the pull rod 160 .

[0034] The pull rod 160 may correspond to the lower hanging portion 220 one by one, and a single upper hanging portion 161 is provided on the pull rod 160. Alternatively, in some embodiments, the pull rod 160 and the lower hanging portion 220 may not correspond one by one, such as a single pull rod 160 is provided with two or more upper hanging portions 161, and the single pull rod 160 corresponds to multiple lower hanging portions 220.

[0035] There are many ways to implement the hanging, such as the upper hanging part 161 is a protrusion provided on the pull rod 160, and the lower hanging part 220 is a hook, which can be hooked on the protrusion. Alternatively, the upper hanging part 161 includes a hanging hole or a hanging groove, and the lower hanging part 220 includes a hanging head, which can be detachably inserted into the hanging hole or the hanging groove. Alternatively, the lower hanging part 220 includes a hanging hole or a hanging groove, and the upper hanging part 161 includes a hanging head, which can be detachably inserted into the hanging hole or the hanging groove. Alternatively, there can be other hanging methods, which are intended to limit each other at least in the direction perpendicular to the model plate 210. The angle between the central axis of the hanging hole or hanging slot and the horizontal line is less than 10 degrees. For example, the insertion direction of the hanging hole or hanging slot is parallel to the horizontal plane, so as to realize the upper hanging part 161 and the lower hanging part 220 being limited in the vertical direction, and the lower hanging part 220 is not easy to slip off the upper hanging part 161. It can be understood that when the angle between the central axis of the hanging hole or hanging slot and the horizontal line is zero degrees, the bottom surface of the model plate 210, that is, the surface in contact with the model, is parallel to the horizontal plane. Due to factors such as manufacturing errors, the angle between the central axis of the hanging hole or hanging slot and the horizontal line may not be zero degrees.

[0036] More specifically, the length direction of the tie rod 160 is perpendicular to the model plate 210, that is, the tie rod 160 extends downward, and a hanging hole or a hanging groove is provided on the tie rod 160. The tie rod 160 is a cylinder, which can be easily processed.

[0037] The lower hanging part 220 is an approximately L-shaped hanging head that can be inserted into the hanging hole. The hanging head includes a vertically extending support area and a hanging area for inserting into the hanging hole. In one embodiment, the hanging hole is a through hole that passes through the radial sides of the pull rod 160, and the hanging hole is an open hole that extends horizontally. The hanging area of ​​the hanging head is adapted to the hanging hole to extend in the horizontal direction, and then plugged into the hanging hole in the horizontal direction to achieve positioning in the vertical direction. In some embodiments, the extension direction of the hanging hole can also be inclined, and the extension direction of the hanging area of ​​the hanging head is adapted to the extension direction of the hanging hole, and is also inclined to extend, and then it can be hung from the side of the hanging hole with a higher position, so that the hanging stability is better and it is not easy to slip.

[0038] The lower hanging part 220 can be arranged at various positions of the model plate 210. For example, in one embodiment, the bottom surface of the model plate 210 is used to contact the model, and the lower hanging part 220 is arranged on the top surface of the model plate 210 opposite to the bottom surface. The lower hanging part 220 and the model plate 210 can be integrally formed. Specifically, there can be ten lower hanging parts 220, each in a group of five, and two groups of lower hanging parts 220 are arranged near opposite sides of the width direction of the main body 100, and the lower hanging parts 220 in the same group are spaced apart along the length direction of the main body 100.

[0039] A forming platform mechanism and three-dimensional forming equipment proposed in the embodiment of the utility model are mainly connected by setting a lower hanging part and an upper hanging part to achieve the fixation of the model plate, facilitate the installation and picking up of the model plate, and ensure the connection strength. In the prior art, there is a model contact plate that uses a spring steel plate as a forming platform, and the spring steel plate is fixed by magnetic attraction. The magnetic attraction method is difficult to take into account both the adsorption strength and the convenience of disassembly. Compared with the prior art, in the present application document, the model plate can be deformed under the action of an external force, and then the model can be demoulded. At the same time, the model plate can be hung on the main body by lateral movement by using a hanging method, without overcoming the magnetic force, making the process of installing and picking up the model plate more convenient, and the model plate can be detachably fixed only by the setting of the structure, avoiding the failure of the magnetic parts due to long-term use, and saving costs at the same time.

[0040] Since the model plate 210 has a certain elasticity, it is easy to vibrate when subjected to external force or during movement. In order to ensure the molding accuracy and the stability of the model, the model plate 210 and the support assembly 110 should be limited in the vertical upward direction. The upper hanging part 161 can limit the lower hanging part 220 in the vertical downward direction. If the lower hanging part 220 is also limited in the vertical upward direction, it will cause the problem that the lower hanging part 220 is not easy to plug in. In order to ensure convenient plug-in and limit the position of the model plate 210 to be more stable, in one embodiment, the main body 100 also includes an adjustment component 130, which is respectively connected to the support assembly 110 and the pull frame component 120 of the fixed component. The fixed component is used to move relative to the support assembly 110 under the action of the external force of the adjustment component 130, and then drive the model plate 210 to move, so as to fit and fix the model plate 210 on the support assembly 110.

[0041] The connection between the adjustment component 130 and the fixed component can be various, such as hanging, plugging or abutting. In the embodiment where the fixed component includes the pull frame component 120 and the pull rod 160, the adjustment component 130 is connected to the support component 110 and the pull frame component 120 respectively, such as abutting the pull frame component 120. The pull rod 160 and the pull frame component 120 are moved as a whole under the action of the adjustment component 130, and the movement can be up and down, thereby causing the model plate 210 hung with the pull rod 160 to move. More specifically, the position of the model plate 210 includes a fastening position and a loose position. When in the fastening position, the model plate 210 abuts against the support component 110, and when in the loose position, at least part of the model plate 210 is separated from the support component 110. The pull frame component 120 is used to move under the action of the external force of the adjustment component 130, so that the pull rod 160 drives the model plate 210 to move between the fastening position and the loose position. It can be understood that the connection in the present application can be understood according to the actual situation, such as understanding that it can include abutment and other situations.

[0042] The pull rod 160 is used to pull the model plate 210 upward from the relaxed position, and then approach the support assembly 110, until the model plate 210 abuts against the support assembly 110, the support assembly 110 applies a downward force to the model plate 210, and the pull rod 160 applies an upward force to the model plate 210, so that the model plate 210 is pressed and limited by the support assembly 110, and then the convenience of hanging and the stability of the position of the model plate 210 in the vertical direction are taken into account. At the same time, because the support assembly 110 presses the model plate 210, the model plate 210 is not easy to move in the horizontal direction, ensuring the stability of the position of the model plate 210.

[0043] In one embodiment, the pull frame assembly 120 is located on the side of the support assembly 110 that is opposite to the model plate 210, and a plurality of clearance holes 111 are provided on the support assembly 110, and the clearance holes 111 correspond to the pull rod 160, and the pull rod 160 is movably connected to the clearance holes 111. Alternatively, in another embodiment, an adjustment inner cavity is provided on the support assembly 110, and the pull frame assembly 120 is located in the adjustment inner cavity, and a plurality of clearance holes 111 are provided on the support assembly 110, and the clearance holes 111 correspond to the pull rod 160, and the pull rod 160 is movably connected to the clearance holes 111. Compared with the embodiment directly arranged above the support assembly 110, the use of the adjustment inner cavity can realize the protection of the pull frame assembly 120 and the attached parts, and make the overall structure of the main body 100 more regular and beautiful.

[0044] When an adjustment cavity is provided on the support assembly 110, Figure 2 , Figure 6 , Figure 8 As shown, the support assembly 110 includes a lower shell 112 and an upper shell 113 , at least one of which is provided with an adjustment groove 1121 , and the lower shell 112 and the upper shell 113 are connected to cooperate with the adjustment groove 1121 to enclose an adjustment inner cavity.

[0045] For example, the lower shell 112 is used to abut against the model plate 210, the adjustment groove 1121 is opened on the lower shell 112, and the upper shell 113 is a similar plate-like structure, covering the notch of the adjustment groove 1121, and connected to the lower shell 112 by bolts, thereby enclosing an adjustment cavity. A plurality of reinforcing ribs can be provided on the upper shell 113 to increase the structural stability of the upper shell 113. A sealing ring can be provided at the connection position between the upper shell 113 and the lower shell 112 to prevent the resin from entering the adjustment cavity, thereby eliminating the need for emotional adjustment of the cavity and increasing the stability of the operation of the molding platform mechanism.

[0046] In one embodiment, when the support assembly 110 is provided with an adjustment inner cavity, the support assembly 110 is also provided with an adjustment opening 114, and the adjustment assembly 130 and the pull frame assembly 120 are connected or interact with each other through the adjustment opening 114, and the connection may be abutment. The size of the adjustment opening 114 and the relationship between the adjustment assembly 130 and the pull frame assembly 120 may be various due to different structures of the pull frame assembly 120, and are described in detail below in conjunction with the embodiments of the adjustment assembly 130 and the pull frame assembly 120.

[0047] In one embodiment, the main body 100 further includes an elastic member 190, which is located between the support assembly 110 and the pull frame assembly 120. The elastic member 190 is used to apply an elastic force to the pull frame assembly 120 to move away from the model plate 210. The elastic member 190 can be arranged between the lower shell 112 and the pull frame assembly 120 in a compressed state, or arranged between the upper shell 113 and the pull frame assembly 120 in a stretched state. When no external force acts on the pull frame assembly 120, the pull frame assembly 120 will have a tendency to move upward, so as to make the model plate 210 abut against the support assembly 110, and then realize that the pull frame assembly 120 can be moved by only applying different degrees of downward pressure to the pull frame assembly 120, which can achieve the effect of simplifying the structure of the adjustment assembly 130.

[0048] In some embodiments, the main body 100 further includes a hanging flexible member, which is disposed on the inner wall of the hanging hole or hanging groove, and the hanging head is used to interact with the hanging hole or hanging groove through the hanging flexible member. When the hanging hole or hanging groove is disposed on the pull rod 160, the hanging flexible member can be disposed on the inner wall of the hanging hole or hanging groove relative to the model plate 210 and away from the model plate 210 to prevent the machining error of the hanging hole or hanging groove, or the machining error of the lower hanging part 220, which leads to the asynchronous movement of the lower hanging part 220 and the uneven movement of the model plate 210.

[0049] In one embodiment, the adjustment assembly 130 includes an action member 131 and a pull member 132, the pull member 132 is rotatably connected to the support assembly 110, the action member 131 is connected to the pull member 132, the action member 131 includes a first end and a second end, and the distance between the first end of the action member 131 and the rotation axis of the action member 131 is greater than the distance between the second end of the action member 131 and the rotation axis of the action member 131. The pull member 132 is used to drive the action member 131 to rotate around the rotation axis of the action member 131 under the action of an external force, so that the first end or the second end of the action member 131 abuts against the pull frame assembly 120, when the first end of the action member 131 abuts against the pull frame assembly 120, the model plate 210 is located in a relaxed position away from the support assembly 110, and when the second end of the action member 131 abuts against the pull frame assembly 120, due to the action of the elastic member 190, the model plate 210 is located in a fastened position close to the support assembly 110.

[0050] The pull member 132 is used for hand-held rotation, and specifically may include a U-shaped rotating handle and a rotating shaft, the rotating shaft being connected to the support assembly 110, such as being connected to a connecting block of the support assembly 110 for connecting the cantilever. The action member 131 may be a cam, and a through hole is provided along the rotation axis of the cam, and the through hole may be a D-shaped through hole, and the rotating shaft is a D-shaped rotating shaft adapted to the through hole, and the rotating shaft is connected to the through hole, and is mutually limited in the circumferential direction with the through hole. When the handle is manually pulled, the cam will be driven to rotate, and then the cam will press down the pull frame assembly 120 to different degrees.

[0051] In one embodiment, the handle includes a long arm in the same direction as the extension of the rotating shaft, and the long arm is always perpendicular to the long diameter of the cam, so that the handle is easier to pull. When the action member 131 is in contact with the pull frame assembly 120 from the second end and rotates to the first end to abut against the pull frame assembly 120, the pull frame assembly 120 will be pushed and then move downward, so that the model plate 210 is away from the support assembly 110, and the support assembly 110 is released from the pressure on the model plate 210, and then the model plate 210 can be disassembled. When the first end is in contact with the pull frame assembly 120 and rotates to the second end to abut against the pull frame assembly 120, the pull frame assembly 120 can move upward under the action of the elastic member 190, so that the model plate 210 is close to the support assembly 110, until the support assembly 110 presses the model plate 210, and then the model plate 210 is limited, and printing can be performed.

[0052] When the elastic member 190 is arranged between the lower shell 112 and the pull frame assembly 120, a spring groove is opened on the lower shell 112. The elastic member 190 can be a spring, and the bottom end is embedded in the spring groove. The elastic member 190 is compressed, which can increase the length of the spring and thus increase the degree of deformation, and make the position of the spring more stable when deformed.

[0053] In a first embodiment of the pull frame assembly 120, as Figure 3-5 As shown, the pull frame assembly 120 includes a pull frame 121 and a pressing head 122 . The pressing head 122 is connected to the pull frame 121 , and the action member 131 abuts against the pressing head 122 .

[0054] The size of the adjustment opening 114 is not limited. The side wall of the adjustment opening 114 may or may not be in contact with the pressure head 122. The pressure head 122 passes through the adjustment opening 114. The top of the pressure head 122 may be higher than the adjustment opening 114, and the action member 131 interacts with the pressure head 122 above the adjustment opening 114. It is also possible that the top of the pressure head 122 is lower than the adjustment opening 114, and the action member 131 partially extends into the adjustment opening 114 and interacts with the pressure head 122. The surface of the pressure head 122 includes a first limiting portion, and the surface of the first end and / or the surface of the second end of the action member 131 includes a second limiting portion. The first limiting portion and the second limiting portion are used to cooperate with each other for limiting. The surface shapes of the first limiting portion and the second limiting portion are adapted to each other, and the first limiting portion and the second limiting surface are used for surface abutment.

[0055] For example, the first limiting portion and the second limiting portion are both arc-shaped surfaces. More specifically, the pressure head 122 is a cylinder extending in the horizontal direction, and the arc-shaped side surface is opposite to the action member 131, and the first end of the action member 131 is provided with an inwardly concave arc surface. On the one hand, when the model plate 210 needs to be removed, when the first limiting portion and the second limiting portion are rotated to interact with each other, there will be a stuck feeling, reminding the user that the action member 131 has been rotated into place, avoiding excessive rotation causing the model plate 210 to rise repeatedly; on the other hand, in the absence of external force, the action member 131 will not rotate easily, so that the pull rod 160 is limited to the height when the model plate 210 moves to the relaxed position, which is convenient for the hanging of the model plate 210 on the next side. It can be understood that the first limiting portion may not be provided, and the surface of the pressure head 122 may be provided as a plane.

[0056] In a second embodiment of the pull frame assembly 120, as Fig.10 As shown, the pull frame assembly 120 includes a pull frame 121 and a pressure head 122, and the first end of the pressure head 122 is connected to the pull frame 121. The pressure head 122 is connected to the adjustment opening 114, and the second end of the pressure head 122 is in contact with the action member 131. The main body 100 also includes a first sealing member 141, which is arranged around the edge of the adjustment opening 114, and the pressure head 122 is connected to the first sealing member 141, and is in contact with or pressed against the first sealing member 141.

[0057] The pressure head 122 is a vertically extending cylinder, and the opening of the adjustment opening 114 can be small in area and have a small interval with the pressure head 122, such as 3 mm. The first seal 141 is annular and made of soft rubber. By setting the first seal 141, one side of the adjustment opening 114 is blocked to prevent the resin from entering the adjustment inner cavity through the adjustment opening 114. The first seal 141 and the adjustment opening 114 can be an interference fit, so that the first seal 141 is stably connected and can be disassembled and replaced.

[0058] Furthermore, the main body 100 further includes a second sealing member 142 , which is disposed around the edge of the clearance hole 111 , and the pull rod 160 penetrates the second sealing member 142 and abuts against or presses the second sealing member 142 .

[0059] The pull rod 160 can have a small interval with the clearance hole 111, such as 3 mm. The second seal 142 is annular and can be made of soft rubber. By setting the second seal 142, one side of the clearance hole 111 is blocked to prevent the resin from entering the adjustment cavity through the clearance hole 111. The first seal 141 and the second seal 142 cooperate to achieve the closure of the adjustment cavity. The second seal 142 and the clearance hole 111 can be an interference fit, so that the second seal 142 is stably connected and can be disassembled and replaced.

[0060] In one embodiment, the adjustment assembly 130 further includes a direction limiting member, which is connected to the support assembly 110 and is located on one side of the pull member 132 . The direction limiting member is used to limit the rotation direction of the pull member 132 .

[0061] For example, the action member 131 can only switch between the first end and the second end abutting the pull frame assembly 120 when it rotates in the preset direction, and when it rotates in the opposite direction to the preset direction, the first end or the second end cannot be moved to a position where it can abut the pull frame assembly 120. Therefore, a direction limiting member is provided to limit the rotation direction of the pull member 132, or in other words, when the user rotates the pull member 132, the action member 131 can be rotated in the preset direction to achieve the switching between the first end and the second end abutting the pull frame assembly 120.

[0062] In order to make the movement of the pull frame 121 more stable, Figure 3-10 As shown, a guide hole 123 is provided on the pull frame 121. The main body 100 also includes at least one guide head 150, which is connected to the support assembly 110 and plugged into the guide hole 123. The guide head 150 slides against the edge of the guide hole 123. In some embodiments, the pull frame assembly 120 also includes a guide plate 124, which is connected to the pull frame 121 and covers a partial area of ​​the guide hole 123, and the pressure head 122 is connected to the guide plate 124. The guide head 150 is inserted between the guide plate 124 and the edge of the guide hole 123, and at least slides against the guide plate 124. For example, the number of the guide heads 150 can be two, and the guide plates 124 are slidably abutted on the opposite sides of the guide plate 124, and then play a guiding role in the movement of the pull frame assembly 120, so that the pull frame assembly 120 only moves in the vertical direction and is not easy to vibrate.

[0063] In one embodiment, if Figure 9-10As shown, the tie rod 160 includes at least one long tie rod 1601 and at least one short tie rod 1602, the short tie rod 1602 and the long tie rod 1601 are arranged at intervals in a preset direction, and the distance between the upper hanging portion 161 on the long tie rod 1601 and the pull frame assembly 120 is greater than or equal to the distance between the end of the short tie rod 1602 and the pull frame assembly 120. The lower hanging portion 220 includes a first lower hanging portion 221 and a second lower hanging portion 222, and the height of the first lower hanging portion 221 relative to the model plate 210 is lower than the height of the second lower hanging portion 222 relative to the model plate 210. The first lower hanging portion 221 can be detachably hung on the long tie rod 1601, and the second lower hanging portion 222 can be detachably hung on the short tie rod 1602.

[0064] In the embodiment where there are ten tie rods 160, the number of long tie rods 1601 and the number of short tie rods 1602 are both five, and the five long tie rods 1601 and the five short tie rods 1602 are respectively arranged in the width direction of the model plate 210 and are spaced apart, and the five long tie rods 1601 extend spaced apart in the length direction of the model plate 210, and the five short tie rods 1602 extend spaced apart in the length direction of the model plate 210. In the hanging direction of the lower hanging part 220, the long tie rod 1601 is located in front of the short tie rod 1602. By ensuring that the distance between the upper hanging portion 161 on the long pull rod 1601 and the pull frame assembly 120 is greater than or equal to the distance between the end of the short pull rod 1602 and the pull frame assembly 120, the upper hanging portion 161 on the long pull rod 1601 and the end of the short pull rod 1602 are staggered in the horizontal direction, and then the model plate 210, or the easily detachable platform assembly 200, can be pushed horizontally, so that the two sets of pull rods 160 distributed in parallel can be hung at the same time, without adjusting the angle of the easily detachable platform assembly 200 for two hangs, and then the hanging process is made simpler and faster while ensuring the hanging strength.

[0065] In one embodiment, if Figure 7 , Fig.11 As shown, at least one slide groove 170 is formed on the main body 100 relative to the model plate 210 , one end of the slide groove 170 passes through the main body 100 to form a slide groove entrance 171 , and the upper hanging portion 161 is at least partially opposite to the slide groove 170 .

[0066] The easily dismantled platform assembly 200 further includes at least one rib plate 230, which is connected to the model plate 210, and a lower hanging portion 220 is provided on the rib plate 230. The number of rib plates 230 corresponds to the number of slide slots 170, and the rib plate 230 is used to be inserted into the slide slot 170 through the slide slot entrance 171, so that the lower hanging portion 220 is hung with the upper hanging portion 161 when moving along the slide slot 170.

[0067] The upper hanging portion 161 is at least partially opposite to the slide groove 170, which means that the upper hanging portion 161 is at least partially located in the slide groove 170, or, the upper hanging portion 161 is at least partially located on the virtual extension line of the slide groove 170, or, in other words, the moving path of the upper hanging portion 161 is at least partially located on the moving path of the lower hanging portion 220 along the slide groove 170.

[0068] In the aforementioned embodiment including the long pull rod 1601 and the short pull rod 1602, the long pull rod 1601 is further away from the chute entrance 171 than the short pull rod 1602, thereby achieving the giving way effect of the short pull rod 1602 for the horizontal movement of the first lower hanging part 221. In the embodiment where the lower hanging part 220 is a hanging head, a notch is provided on the rib plate 230 to form the lower hanging part 220.

[0069] When installing the model plate 210, align the end of the rib plate 230 with the chute entrance 171, and push the model plate 210 into the chute 170. The chute 170 is used to guide the movement of the rib plate 230, so that the lower hanging part 220 can be accurately hung on the upper hanging part 161, making the installation process of the model plate 210 more convenient, and there is no need to align multiple lower hanging parts 220 and upper hanging parts 161 in sequence. At the same time, the interaction between the chute 170 and the rib plate 230 also makes the movement of the model plate 210 more stable, and the rib plate 230 is not easy to deform under the pulling or pushing force of the upper hanging part 161. In the embodiment where the lower hanging part 220 includes a first lower hanging part 221 and a second lower hanging part 222, the number of the rib plates 230 can be five, and a first lower hanging part 221 and a second lower hanging part 222 are formed on any rib plate 230. The rib plate 230 and the model plate 210 can be integrally formed.

[0070] In one embodiment, the width of the chute 170 includes a decreasing trend in the direction away from the chute entrance 171. For example, if the width of the chute 170 at the chute entrance 171 is greater than the thickness of the rib plate 230, on the one hand, the chute entrance 171 is wider so that the rib plate 230 can be easily inserted into the chute 170; on the other hand, the side away from the chute entrance 171 is narrower, which can better limit the position of the rib plate 230 and provide a differentiated feel for the user to push the model plate 210 to move, which can prompt the user that it is about to move into place. Specifically, the width of the chute 170 away from the chute entrance 171 is less than or equal to the thickness of the rib plate 230, and the rib plate 230 can be moved into place by applying force to squeeze the inner wall of the chute 170 to deform, and fit tightly with the inner wall of the chute 170. The deformation of the inner wall of the chute 170 can be achieved by the elastic deformation of the material of the support component 110 itself, or the main body 100 also includes a chute flexible member, which is arranged on the inner wall of at least one side of the chute 170 away from the chute entrance 171, such as being arranged on the side walls of the opposite sides, in order to make the forces on both sides of the rib plate 230 uniform. The distance between the two chute flexible members is less than the thickness of the rib plate 230. When the rib plate 230 is inserted between the two chute flexible members, the two chute flexible members will be squeezed, and then the insensitive force of movement will be provided, which plays a role in prompting the movement to be in place, and the chute flexible member plays a role in squeezing and limiting the rib plate 230. The width of the slide groove 170 away from the slide groove entrance 171 can be set according to the difficulty of deformation of the inner wall of the slide groove 170. For example, the width of the slide groove 170 away from the slide groove entrance 171 is greater than 0.1 mm less than the thickness of the rib plate 230 and less than 3 mm. This is intended to provide a differentiated feel while taking into account the smooth pushing of the rib plate 230 to avoid excessive extrusion that may cause the rib plate 230 to fail to be pushed into place.

[0071] In one embodiment, the chute 170 is closed on the side opposite to the chute entrance 171, which can limit the final position of the rib plate 230 or the model plate 210. Alternatively, in some embodiments, the chute 170 can also be through on the side opposite to the chute entrance 171.

[0072] In one embodiment, the main body 100 includes a support assembly 110 and a clamping plate 180. The support assembly 110 is provided with an empty slot 115 opposite to the model plate 210. The clamping plate 180 is located in the empty slot 115. The end of the clamping plate 180 and the opening edge of the empty slot 115 are located in the same plane. The slide groove 170 is provided on the clamping plate 180. The clamping plate 180 is also provided with a clearance notch 181. The clearance notch 181 is opposite to the clearance hole 111 and is used to make way for the pull rod 160. The end of the clamping plate 180 and the opening edge of the empty slot 115 are used to abut the model plate 210.

[0073] The end of the clamping plate 180 refers to the end of the clamping plate 180 close to the model plate 210, or the bottom end of the clamping plate 180. In the embodiment where the empty slot 115 and the clamping plate 180 are not provided, the lower surface of the support assembly 110 between the slide grooves 170 is used to abut the model plate 210. In the embodiment where the empty slot 115 and the clamping plate 180 are provided, the end of the clamping plate 180 and the opening edge of the empty slot 115 are used to abut the model plate 210. The provision of the empty slot 115 greatly reduces the weight of the support assembly 110, or the lower shell 112, making it easier to drive the molding platform.

[0074] In one embodiment, the support assembly 110 is further provided with at least one liquid guide notch 116 connected to the empty groove 115 and the outside of the support assembly 110, so that the resin can be discharged from between the slide groove 170 and the plate rib 230, or from the gaps along the edges of other empty grooves 115 to the top of the model plate 210 and between the empty grooves 115. In addition, in some embodiments, the model plate 210 is provided with at least one liquid guide hole for discharging the resin between the top of the model plate 210 and the empty grooves 115.

[0075] In one embodiment, if Fig.11 As shown, the easily detachable platform assembly 200 further includes two handles 240, which are respectively connected to opposite sides of the model plate 210. The handles 240 extend perpendicularly to the model plate 210.

[0076] The handle 240 may be a U-shaped handle 240, which is used to facilitate the movement or bending of the model plate 210. At the same time, the distance between the two handles 240 is adapted to the distance between the two opposite sides of the support assembly 110, so that when the model plate 210 is installed, the two handles 240 can respectively abut against the support assembly 110 from the opposite sides of the support assembly 110, and then play a role in assisting the alignment of the rib plate 230 and the chute entrance 171, and guiding the movement of the model plate 210. When the rib plate 230 extends in the width direction of the model plate 210, the two handles 240 are respectively arranged at the two ends of the length direction of the model plate 210. In addition, the model plate 210 can also be subjected to force through the handles 240, so that the model plate 210 is easier to bend.

[0077] In one embodiment, the easily detachable platform assembly 200 further includes at least one roller 250 , which is rotatably connected to the handle 240 , and the roller 250 is used to roll on a side of the main body 100 opposite to the model plate 210 .

[0078] One or more rollers 250 may be provided on the handle 240, and the height of the roller 250 from the model plate 210 is such that when the roller 250 is rollingly connected to the side of the main body 100 opposite to the model plate 210, the height of the lower hanging portion 220 is opposite to the upper hanging portion 161. During installation, the handle 240 is aligned, the roller 250 is pressed against the upper surface of the main body 100 near the edge, and then the handle 240 or the model plate 210 is pushed, so that there is no need to provide an upward pulling force to the easily detachable platform assembly 200, and only pushing is required, making it more convenient to install the easily detachable platform assembly 200.

[0079] In one embodiment, the easily disassembled platform assembly 200 further includes a positioning plate 260 , and the positioning plate 260 includes a first vertical positioning surface and a second vertical positioning surface, the first positioning surface is connected to the surface of the model plate 210 , and the second positioning surface is connected to the surface of the handle 240 .

[0080] There are two positioning plates 260, which are arranged one by one corresponding to the handles 240. The first positioning surface and the second positioning surface of the positioning plate 260 are used to limit the angle between the handle 240 and the model plate 210, so that the overall structural stability of the easily dismantled platform assembly 200 is better.
