Description

Technical Field

[0001] The invention relates to the field of foaming technology, and in particular to a box foaming clamp for refrigerator production. Background Art

[0002] The refrigerator body is foamed by winding a copper tube on the surface of the inner shell and arranging an outer shell in between, so that an injection foaming cavity is formed between the outer shell and the inner shell. After the foaming agent is injected into the foaming cavity, the inner shell and the outer shell are foamed and filled into shape by the foaming agent.

[0003] Chinese patent application CN116373201A discloses an integrated mold and clamp device for a beauty refrigerator, including an operating platform, a side clamp assembly and a top clamp assembly. A lifting frame is placed on the top of the operating platform, and a foaming mold box is placed on the lifting frame. The side clamp assembly is used to clamp and fix the four sides of the foaming mold box, and the top clamp assembly is used to clamp and fix the top surface of the foaming mold box. After placing the foaming mold box on the operating platform, it is convenient to clamp and fix the foaming mold box through the side clamp assembly and the top clamp assembly. The clamping and fixing of the foaming mold box is stable and reliable, and the operation is convenient, which avoids the occurrence of foaming and swelling, thereby ensuring the production quality of the foamed products and meeting the production needs of high-quality products.

[0004] The above patents and prior art have the following problems:

[0005] During the foaming process of the box, when the outer shell is a thin plate, it is easy to cause uneven bending in the middle and on both sides during the clamping and transfer process. When the uneven plate is combined into a mold on the outside of the box, it will cause uneven force on the foaming agent, thereby affecting the molding quality of the box. When the plate is clamped and assembled in the mold, it is necessary to use tape to fix it on the outside to combine the two outer shell plates. However, after the tape is combined with the plate and the box through foaming, the residual tape will increase the difficulty of cleaning. Summary of the invention

[0046] Beneficial effects of the present invention:

[0047] First, by starting the rotating driving source on the side of the bottom module, the rotating driving source drives the rotating ring to rotate, and the rotating ring drives the transmission member to rotate through the teeth on the top thereof, and the rotation of the transmission member drives the rotating rod to rotate, and the rotation of the rotating rod drives the threaded movement of the bottom of the driven block that cooperates with it through the thread on its surface, so that the rotating rod drives the driven block to approach the surrounding frame through the thread, and during the movement of the driven block, it drives the template 1 and template 2 on the top thereof to move, so that the template 1 and template 2 are respectively close to the corresponding surrounding frames, so that the side shell plates are finally clamped between the template 1 and its corresponding surrounding frame and between the template 2 and its corresponding surrounding frame, respectively, thereby reducing the use of tape in the prior art and the subsequent cleaning process of the tape residue on the shell surface, thereby improving work efficiency.

[0048] Second, as the surrounding frame approaches the inner box body, the fixed-length pull rope between the rollers on the outside of the shell plate and the top mounting plate will be pulled by the roller, that is, the roller fixes and restricts one end of the pull rope, and the other end of the pull rope is fixed to the surface of the shell plate and moves with the surrounding frame. The fixed-length pull rope moves with the movement of the surrounding frame under the fixed restriction of the roller, and the roller pulls the shell plate up along the extension groove through the pull rope. The movement of the shell plate will drive the rolling roller to move inside the surrounding frame, so that the rolling roller rolls the surface of the side shell plate clamped and restricted by the surrounding frame and the back plate, so that the surface of the side shell plate is rolled flat, thereby reducing the unevenness of the middle part of the box shell and reducing the problem of uneven surface of the box shell that the foaming agent cannot be evenly distributed during injection and foaming.

[0049] 3. The folded edge at the bottom of template 1 is inserted into the horizontal connecting groove on the corresponding side to complete the construction of the side of the injection mold cavity, which will make the folded edges on the left and right sides of the corresponding side shell plate of template 2 located on the inner side of the side shell plate corresponding to template 1, so that the folded edges on the left and right sides of template 2 increase the contact surface between the adjacent side shell plates, thereby strengthening the supporting structure and increasing the contact sealing area between the adjacent side shell plates. The upper and lower bent edges of the side shell plates increase the upper and lower sealing areas of the mold cavity and reduce the leakage of the foaming agent through the connecting gap.

[0050] Fourth, the top template on the top of template one is turned over to the top of template one and template two, and the lock buckle one on the surface of the top template on the left and right sides is buckled with the corresponding hook two, and the lock buckle two on the surface of template two is buckled with the hook one on the surface of the top template corresponding to it, so as to complete the overall clamping and foaming locking of the side shell plate and the top shell plate, and the semicircular holes in the middle of the top template on the top of template one on the left and right sides are closed, and the injection hole is aligned with the through hole on the top surface of the top shell plate to facilitate the starting of the reciprocating driving source, so that the hollow rod at the bottom passes through the injection hole and is inserted into the through hole on the top surface of the top shell plate, and the foaming agent delivered by the external screw extruder is pushed into the inside of the foaming cavity through the external pipe and the hollow conveying of the hollow rod, so that the box body is foamed between the inner box body, the side shell plate and the top shell plate.

Of course, gears can also be installed on the top of the rotating driving source 20111, so that teeth are set on the contact surface between the rotating ring 2013 and the rotating driving source 20111, so that the rotating driving source 20111 can mesh with the teeth on the contact surface of the rotating ring 2013 through the gear on its top, thereby realizing meshing transmission.

[0100] The bottom of the vertical plate 105 is fixedly connected to a surrounding frame 106 .

[0101] Operation process:

[0102] like Figure 1-9 As shown, the inner box 301 is manually turned upside down on the surface of the stacking block 203 and the foaming unit 2 is pushed into the corresponding cavity 1011, so that the docking groove 2014 corresponds to the protrusion 1012, and through the restriction of the corresponding cavity 1011 and the snap-fit ​​cooperation between the docking groove 2014 and the protrusion 1012, the template 1 204 and the template 2 205 in the foaming unit 2 are aligned with the bottom of the surrounding frame 106;

[0103] The side shell plate 302 to be processed is manually placed on the sides of the template 1 204 and the template 2 205, so that the side shell plate 302 on the side of the template 2 205 is inserted into the space between the two positioning blocks 2055 at the bottom of the template 2 205 through the folded edge 3021 at the bottom, and the folded edges 3021 on the left and right sides of the side shell plate 302 are placed on the top surface of the positioning block 2055 to be supported, so that the side shell plate 302 on the side of the template 2 205 is supported and positioned;

[0104] The side shell plate 302 at the side of the template 1 204 is inserted into the space between the two positioning blocks 2055 at the bottom of the template 1 204 through the folded edge 3021 at its bottom, and the bottom surface of the folded edge 3021 at the bottom of the side shell plate 302 is in contact with the cross plate 2045 and supported by the cross plate 2045, so that the side shell plate 302 at the side of the template 1 204 is supported and positioned. At this time, the bottom surfaces of the folded edge 3021 at the bottom of the side shell plates 302 at the sides of both templates 1 204 and template 2 205 are coplanar.

[0105] Then, the telescopic driving source 104 is started, so that the telescopic driving source 104 drives the vertical plate 105 and the surrounding frame 106 at the bottom thereof to move downward, so that the four surrounding frames 106 are respectively moved to the sides of the template 1 204 and the template 2 205, and correspond to the back plates 2056 on the surfaces of the template 1 204 and the template 2 205. At this time, the straight plate portion of the folding plate 1051 is inserted into the notch of the docking groove plate 20541;

[0106] Then, by starting the rotating driving source 20111 on the side of the bottom module 201, the rotating driving source 20111 drives the rotating ring 2013 to rotate, so that the rotating ring 2013 drives the transmission member 2022 to rotate through the teeth on the top thereof, and the rotation of the transmission member 2022 drives the rotating rod 2021 to rotate, and the rotation of the rotating rod 2021 drives the thread on the bottom of the driven block 2023 to move through the thread on its surface, so that the rotating rod 2021 drives the driven block 2023 to move toward the surrounding frame 106 through the thread.

Example

[0107] This embodiment is different from the first embodiment in that:

[0108] like Figure 9-13 As shown, the mounting groove block 202 on the bottom surface of the top mounting plate 102 is correspondingly installed with a mounting block 1025 at a position on the outer circumferential surface of the top mounting plate 102, a convex rod 10251 is installed in the middle of the mounting block 1025, a roller 10253 is rotatably installed on the surface of the convex rod 10251, a reset member 10252 is elastically connected between the convex rod 10251 and the roller 10253, the reset member 10252 is sleeved on the surface of the convex rod 10251, a pull rope 10254 is wound around the surface of the roller 10253, the pull rope 10254 on the surface of the roller 10253 passes through the moving block 103 and is fixedly connected to the shell buckle plate 10612, and the pull rope 10254 is an elastic rope;

[0109] A through-hole 1052 is provided on the surface of the vertical plate 105, and a folding plate 1051 is slidably installed inside the through-hole 1052. The folding plate 1051 is composed of a flat plate and a straight plate vertically downward. A vertical block 10512 is fixedly installed on the top of the folding plate 1051, and the vertical block 10512 is elastically connected to the vertical plate 105 through a locking piece 10513. An opening 10511 is provided on the surface of the folding plate 1051, that is, the opening 10511 is arranged on the surface of the flat plate, and an auxiliary plate 10613 and a pull rope 10254 are movably arranged inside the opening 10511, and a plurality of balls 10514 are movably embedded in the contact surface between the opening 10511 and the auxiliary plate 10613.

[0110] When the surrounding frame 106 returns to the outside of the top plate 102 under the reverse drive of the rotating drive source 20111, the rolling roller 1063 and the shell plate 10612 fall back to the bottom of the surrounding frame 106 under the action of their own gravity. At this time, the pull rope 10254 is not straightened. At this time, the reset member 10252 resets and drives the winding roller 10253 to reverse, so that the pull rope 10254 is wrapped around the surface of the winding roller 10253. The reset member 10252 is preferably a winding spring.

[0111] like Figure 11-13 As shown, a movable groove 1061 is provided on the side of the length side of the surrounding frame 106, a roller 10611 is slidably provided inside the movable groove 1061, an extension groove 1062 is provided on the surface of the surrounding frame 106 to communicate with the movable groove 1061, a shell plate 10612 is movably provided inside the extension groove 1062, and the shell plate 10612 passes through the extension groove 1062 and is sleeved on the side of the roller 10611;

[0112] The roller 10611 is arranged on a partial rolling sleeve inside the surrounding frame 106 and is provided with a rolling roller 1063. The surface of the shell plate 10612 opposite to the surrounding frame 106 is fixedly connected with an auxiliary plate 10613.

[0113] It should be noted that the reciprocating propulsion source 1021 and the telescopic driving source 104 are preferably cylinders or electric telescopic rods, and are powered by external energy and controlled by the same PLC.

The rotary driving source 20111 is preferably a servo motor or a unidirectional asynchronous reduction motor, and is powered by external energy and controlled by the same PLC.

[0114] The rest of the structure is the same as that of the first embodiment.

[0115] Operation process:

[0116] After the side shell plate 302 is clamped, the rotating driving source 20111 on the side of the top plate 102 and the bottom module 201 is started synchronously, and the direction and speed of the two are the same, so that the rotating driving source 20111 drives the rotating ring 2013 inside the top plate 102 and the bottom module 201 to rotate, so that the rotating ring 2013 drives the transmission member 2022 and the rotating rod 2021 to rotate, and the rotating rod 2021 drives the driven block 2023 to move toward the inner box body 301 at the top of the installation slot block 202 through the thread, so that the driven block 2023 on the surface of the top plate 102 drives the movement of the surrounding frame 106 and the driven block 2023 on the surface of the bottom module 201 drives the movement of the template 1 204 and the template 2 205 synchronously, so that the side shell plate 302 on the surface of the template 1 204 and the template 2 205 is always clamped between the surrounding frame 106 and the corresponding template 1 204 or template 2 205, thereby ensuring the stability of transfer clamping;

[0117] As the surrounding frame 106 approaches the inner box body 301, the fixed-length pull rope 10254 between the shell plate 10612 and the roller 10253 outside the top plate 102 is pulled by the roller 10253, that is, the roller 10253 fixes and restricts one end of the pull rope 10254, and the other end of the pull rope 10254 is fixed to the surface of the shell plate 10612 and moves with the movement of the surrounding frame 106, so that the fixed-length pull rope 10254 moves with the movement of the surrounding frame 106 under the fixed restriction of the roller 10253. 253 pulls the shell plate 10612 upward along the extension groove 1062 through the pull rope 10254, and the movement of the shell plate 10612 will drive the rolling roller 1063 to move inside the surrounding frame 106, so that the rolling roller 1063 rolls the surface of the side shell plate 302 clamped and restricted by the surrounding frame 106 and the back plate 2056, so that the surface of the side shell plate 302 is rolled flat, reducing the unevenness of the middle part of the box shell, and reducing the problem of uneven distribution of the foaming agent during injection and foaming due to the uneven surface of the box shell.

[0118] It should be noted that, before the surrounding frame 106 moves downward to correspond to the back plate 2056 and has not approached the inner box body 301, the pull rope 10254 on the surface of the roller 10253 is pulled by the gravity of the rolling roller 1063 and the shell plate 10612 and the downward movement of the surrounding frame 106. Except for the pull rope 10254 fixed to the surface of the roller 10253, the pull rope 10254 wrapped around the surface of the roller 10253 is all pulled away from the roller 10253. At this time, the pull rope 10254 between the shell plate 10612 and the moving block 103 is straightened, and the rolling roller 1063 is located at the bottom of the surrounding frame 106.

[0119] During the upward movement of the shell plate 10612, the auxiliary plate 10613 is always restricted in the empty opening 10511 in the folding plate 1051, so that the shell plate 10612 connected to the auxiliary plate 10613, and the roller 10611 and the rolling roller 1063 inside the shell plate 10612 move more stably, and as the shell plate 10612 drives the auxiliary plate 10613 to move, the slope block 10614 on the surface of the auxiliary plate 10613 gradually enters the empty opening 10511, so that the slope block 10614 The bottom pushes up the folding plate 1051 to move outwards, and the folding plate 1051 is inserted into the inside of the docking groove plate 20541. The outward movement of the folding plate 1051 drives the push frame plate 2054 to move outwards, and finally makes the upper and lower folding edges 3021 of the shell plate 302 on the surface of the template 1 204 be squeezed and bent as the front end of the push frame plate 2054 moves, and the upper and lower folding edges 3021 of the template 2 205 are squeezed and bent as the front end of the push frame plate 2054 moves, so that the folding edges 3021 are pushed flat by the movement of the push frame plate 2054;

[0120] When the template 1 204 and the template 205 move to the side of the inner box 301, the rotation driving source 20111 on the side of the bottom module 201 stops rotating, and the rotation driving source 20111 on the side of the top plate 102 continues to rotate. At this time, the push frame plate 2054 completes the bending of the folding edge 3021, and the rolling roller 1063 is pulled to the top of the surrounding frame 106 by the pull rope 10254. It should be noted that the thickness of the push frame plate 2054 is greater than the folding edge 3021. 021 width, i.e., the thickness of the push frame plate 2054 is greater than the distance between the surface farthest from the side shell plate 302 and the side shell plate 302 after the folding edge 3021 is bent. When the push frame plate 2054 moves to complete the bending of the folding edge 3021, the outermost side of the folding edge 3021 does not contact the surface of the vertical plate 105, and the bent folding edge 3021 is located between the surrounding frame 106 and the push frame plate 2054. At this time, part of the push frame plate 2054 is inside the receiving groove 2053.

[0121] The rotating driving source 20111 on the side of the top mounting plate 102 continues to rotate, so that the surrounding frame 106 is away from the template 1 204 and the template 2 205, and pulls the pushing frame plate 2054 that has been bent at the folding edge 3021 to continue to move outward, that is, the part of the pushing frame plate 2054 located inside the accommodating groove 2053 moves outward. At this time, the side shell plate 302 is still located between the pushing frame plate 2054 and the surrounding frame 106. When the surrounding frame 106 leaves the inside of the folding edge 3021, the telescopic driving source 104 controls the surrounding frame 106 to lift and reset. In this process, the pull rope 10254 is pulled elastically. The push frame plate 2054 is within the extended range, and part of the push frame plate 2054 is still located inside the accommodating groove 2053. The push frame plate 2054 will stop at the position where the surrounding frame 106 is lifted under the support of the telescopic member 20542 to support the folded edge 3021. At this time, the inner top surface of the bottom of the push frame plate 2054 in contact with the side shell plate 302 is coplanar with the bottom surface of the transverse connecting groove 30111. The opening width of the transverse connecting groove 30111 is greater than the thickness of the folded edge 3021, so that the push frame plate 2054 can complete the connection and guidance of the folded edge 3021 at the bottom of the side shell plate 302 relative to the transverse connecting groove 30111.

[0122] Then, the rotary driving source 20111 on the side of the bottom module 201 continues to move, so that the push frame plate 2054 contacts the bottom frame plate 3011 at the bottom of the inner box body 301, and under the obstruction of the bottom frame plate 3011, the push frame plate 2054, the telescopic member 20542 and the positioning block 2055 gradually retract into the inside of the accommodating groove 2053 and the shrinking groove 20531, so that the side shell plate 302 and the folded edge 3021 inside the push frame plate 2054 are gradually exposed by the push of the template 1 204 and the template 2 205, and as the template 1 204 and the template 2 205 continue to move, the folded edge 3021 at the bottom of the side shell plate 302 is inserted into the inside of the transverse connecting groove 30111;

[0123] It should be noted that, by designing the number of teeth of the transmission member 2022 on the outer side of the bottom of the template 1 204 and the template 2 205 and the number of teeth of the transmission member 2022 on the outer side of the upper surrounding frame 106 corresponding to the transmission member 2022 on the outer side of the bottom of the template 1 204 and the template 2 205, the number of teeth of the transmission member 2022 on the outer side of the rotating rod 2021 at the bottom of the template 2 205 and the number of teeth of the transmission member 2022 on the outer side of the upper surrounding frame 106 corresponding to the transmission member 2022 are the same, and the number of teeth of the transmission member 2022 on the outer side of the rotating rod 2021 at the bottom of the template 1 204 and the number of teeth of the transmission member 2022 on the outer side of the upper surrounding frame 106 corresponding to the transmission member 2022 are the same;

[0124] The number of teeth of the transmission member 2022 on the outer side of the rotating rod 2021 at the bottom of the second template 205 and the number of teeth of the transmission member 2022 on the outer side of the upper surrounding frame 106 are smaller than the number of teeth of the transmission member 2022 on the outer side of the rotating rod 2021 at the bottom of the first template 204 and the number of teeth of the transmission member 2022 on the outer side of the upper surrounding frame 106, so that the rotating rod 2021 at the bottom of the second template 205 and the rotating rod 2021 at the top of the corresponding surrounding frame 106 are driven by the transmission member 20 The rotation speed of the transmission 22 is greater than the rotation speed of the bottom rotating rod 2021 of the template 1 204 and the corresponding rotating rod 2021 at the top of the surrounding frame 106 driven by the transmission member 2022, so that the folded edge 3021 at the bottom of the side shell plate 302 on the surface of the template 2 205 is preferentially inserted into the inside of the horizontal connecting groove 30111, and the folded edges 3021 on the left and right sides of the side shell plate 302 are located at the top of the bottom frame plate 3011, so that the template 2 205 drives the side shell plate 302 to fit the surface of the bottom frame plate 3011;

[0125] Then, the template 1 204 will bring its side shell plate 302 to fit the folded edge 3021 surfaces on the left and right sides of the side shell plate 302 on the side of the template 2 205, and insert the folded edge 3021 at the bottom of the template 1 204 into the corresponding side of the horizontal connecting groove 30111 to complete the construction of the side of the foaming cavity. At this time, the frame plate 2054 and the telescopic member 20542 are pushed back into the inside of the accommodation groove 2053 and the positioning block 2055 is retracted into the inside of the inner shrinkage groove 20531, and the frame plate 2054 and the positioning block 2055 are pushed to be coplanar with the back plate 2056 on the surface of the template 1 204 and the template 2 205;

[0126] The folded edge 3021 at the bottom of the template 1 204 is inserted into the corresponding side of the horizontal groove 30111 to complete the construction of the side of the injection mold cavity, so that the folded edges 3021 on the left and right sides of the corresponding side shell plate 302 of the template 2 205 are bent and located on the inner side of the side shell plate 302 corresponding to the template 1 204, so that the folded edges 3021 on the left and right sides of the template 2 205 are bent to increase the contact surface between the adjacent side shell plates 302, thereby strengthening the support structure and improving the contact sealing between the adjacent side shell plates 302. The upper and lower bent edges 3021 of the side shell plate 302 increase the upper and lower sealing areas of the cavity and reduce the leakage of the foaming agent through the connecting gap. It should be noted that template 1 204 is equivalent to constructing the length side of the cavity, and template 2 205 is equivalent to constructing the width side of the cavity, so that the length of template 1 204 is greater than the length of template 2 205, and the relative transverse grooves 30111 of the two also follow the same rule that the transverse grooves 30111 corresponding to template 1 204 are longer than the transverse grooves 30111 corresponding to template 2 205.

[0127] When the template 1 204 and the template 2 205 push the side shell plate 302 to contact the bottom frame plate 3011, a foaming space is formed between the inner box body 301 and the side shell plate 302. The bending of the top folding edge 3021 of the side shell plate 302 makes it easy to manually place the top shell plate 303 on the surface of the folding edge 3021 at the top of the side shell plate 302 after the mold is closed between the template 1 204 and the template 2 205 and the bottom frame plate 3011, so that the side shell plate 302 at the side of the template 1 204 and the template 2 205 supports the top shell plate 303 through the folding edge 3021 at the top, so that the inner box body 301 and the side shell plate 302 and the top shell plate 303 are convenient to form a foaming cavity.

[0128] The top template 2041 on the top of the template 1 204 is manually flipped to the top of the template 1 204 and the template 2 205. It should be noted that the width of the top template 2041 is greater than the width of the template 1 204 and its outer surface is flush with the outer surface of the template 2 205, and the lock 1 2043 on the surface of the top template 2041 on both sides is buckled with the corresponding hook 2044, and the lock 2051 on the surface of the template 2 205 is buckled with the corresponding hook 1 2042 on the surface of the top template 2041, so as to complete the overall connection between the side shell plate 302 and the top shell plate 303. The foaming is clamped and locked, and the semicircular hole in the middle of the top template 2041 on the top of the left and right side templates 204 is closed. The injection hole is aligned with the through hole on the top surface of the top shell plate 303, which is convenient for starting the reciprocating driving source 1021, so that the hollow rod 1023 at the bottom passes through the injection hole and is inserted into the through hole on the top surface of the top shell plate 303, and the foaming agent delivered by the external screw extruder is pushed into the interior of the foaming cavity through the external pipe 10231 and the hollow conveying of the hollow rod 1023, so that the box body is foamed and formed between the inner box body 301, the side shell plate 302 and the top shell plate 303.
