Description

Technical Field

[0001] This invention relates to the field of molding technology, specifically to a demolding device and a continuous production system. Background Technology

[0002] Expandable thermoplastic materials include, but are not limited to, expandable polystyrene (EPS), expandable polypropylene (EPP), expandable polyolefin (EPO), expandable thermoplastic polyurethane (ETPU), and all other materials that can be physically foamed and molded by heating.

[0003] Currently, the molding production of these products typically employs a single "molding machine" operation mode. In this mode, the mold is fixedly mounted on the molding machine and remains stationary throughout the entire processing. The molding machine sequentially performs processes such as mold closing, filling, steam heating, cooling, mold opening, and demolding until the entire production cycle is completed and the product is ejected. This production method suffers from long production cycles and low efficiency. Furthermore, the repeated switching between heating and cooling states on the same molding machine leads to high energy consumption and significant energy waste.

[0004] The existing demolding mechanism is located inside the molding machine and only performs demolding operations on molds that are fixedly connected inside the molding machine. It is obviously not suitable for molds that are transported by a conveyor line. Summary of the Invention

[0005] The first objective of this invention is to provide a demolding device that can perform demolding operations on molds conveyed by a conveyor line.

[0006] A second objective of the present invention is to provide a continuous production system comprising the above-described demolding device.

[0007] To achieve the aforementioned first objective, the present invention provides a demolding device, comprising a fixed frame, a first lifting assembly, a second lifting assembly, and a base. The first lifting assembly is disposed at the lower part of the fixed frame and includes a demolding support seat that can move up and down. The second lifting assembly is disposed at the upper part of the fixed frame and includes a demolding frame that can move up and down. The demolding frame is provided with an ejector plate and an ejection drive assembly. The ejector plate is disposed within the demolding frame, and the ejection drive assembly can drive the ejector plate to move up and down. The base is disposed between the demolding support seat and the demolding frame. The base includes a first base and a second base. The second base is detachably disposed on the first base. The first base is provided with a lower mold support portion, and the second base is provided with an upper mold support portion. Both the lower mold support portion and the upper mold support portion are disposed within the demolding frame and are both disposed below the ejector plate. The second base can be detachably connected to the demolding frame and move with the demolding frame.

[0008] As can be seen from the above scheme, the demolding support is used to lift the base and the mold on it, so that the base is temporarily separated from the conveying surface of the conveying component, which facilitates the mold opening and demolding operations. It is especially suitable for continuous production methods that use the conveying component to continuously convey the mold. The lower mold is set on the first base, and the upper mold is set on the second base, and the second base can be connected to the demolding frame. When the mold is opened, the demolding frame drives the second base and the upper mold to move upward, completing the mold opening. At this time, the product is left in the upper mold. The upper mold is equipped with an ejection component. The ejection drive component drives the ejection plate to move downward, so that the ejection component ejects the product downward, thereby realizing demolding. This invention can perform mold opening and demolding operations sequentially on the molds conveyed to the demolding station. It has the advantages of simple structure, convenient operation, and suitability for continuous production.

[0009] A further design involves sealing the demolding frame with the second base to form a cavity; the demolding frame is connected to an air inlet pipe, which communicates with the cavity.

[0010] As can be seen from the above scheme, during demolding, compressed air is injected into the cavity through the air inlet pipe, thereby filling the gap between the upper mold and the product, and using air pressure to effectively assist in demolding the product.

[0011] A further embodiment is that a first locking component is connected between the first base and the second base; a first unlocking component is provided on the demolding frame, which can force the first locking component to unlock.

[0012] As can be seen from the above scheme, before the mold is opened, the first locking component is in a locked state to ensure that the second base is reliably connected to the first base; when the mold needs to be opened, the demolding frame moves down and the first unlocking component forces the first locking component to release the lock, so that the second base is separated from the first base.

[0013] A further embodiment includes a first locking component comprising a fixed base, a locking element, a first elastic element, and a sliding block. The fixed base is provided with a locking groove, an unlocking groove, and a sliding groove. The sliding groove communicates with the locking groove and the unlocking groove, respectively. The locking element is detachably disposed in the locking groove. The sliding block is disposed in the sliding groove. The first end of the sliding block engages with the locking element. The first elastic element elastically abuts against the second end of the sliding block between the second end of the sliding block and the groove wall of the sliding groove. The first unlocking component can be inserted into the unlocking groove to push the sliding block away from the locking element.

[0014] As can be seen from the above solutions, the mechanical locking method has the advantages of simple structure and high reliability.

[0015] A further embodiment is that a second locking component is connected between the demolding frame and the second base; a second unlocking component is provided on the demolding frame, which can force the second locking component to unlock.

[0016] As can be seen from the above scheme, before the mold is opened, the second locking component is first locked to fix the demolding frame to the second base, so that the demolding frame can drive the second base and the upper mold on it to move upward together to realize the mold opening; after the product is demolded, the demolding frame drives the second base to reset and move downward, and the second unlocking component forces the second locking component to unlock, thereby realizing the separation of the demolding frame and the second base.

[0017] A further embodiment is that the first base has a first through hole, and the second base has a second through hole communicating with the first through hole; a reinforcing component is provided on the demolding frame, the reinforcing component includes a rotary drive device and a reinforcing hook, the reinforcing hook passes through the second through hole and is set in the first through hole, the rotary drive device can drive the reinforcing hook to rotate at a preset angle, so that the reinforcing hook abuts against the bottom wall of the second base.

[0018] As can be seen from the above scheme, when the demolding frame drives the second base away from the first base, the reinforcing hook is rotated 90° to connect with the bottom wall of the second base and hook the second base, which can effectively prevent it from falling accidentally.

[0019] A further embodiment is that the ejection drive assembly includes a first drive device, a sleeve, a drive rod, and a slider. The sleeve is located outside the demolding frame, and the drive rod and slider are both located inside the sleeve. The first end of the slider is connected to the drive rod, and the second end of the slider extends into the demolding frame and is connected to the ejector plate. The first drive device drives the slider to move up and down through the drive rod.

[0020] A further option is to use a lead screw as the drive rod and a sliding sleeve as the sliding component. A first nut is installed inside the sliding sleeve, and the lead screw is inserted into the sliding sleeve and connected to the first nut for transmission.

[0021] As can be seen from the above scheme, the lifting stroke of the ejector plate can be precisely controlled through the transmission connection between the lead screw and the first nut. This ensures that the ejector assembly accurately ejects the product and also avoids the ejector plate failing to reset properly after ejection, which would interfere with subsequent production cycles.

[0022] A further embodiment includes a demolding device that further comprises a conveying assembly and a product receiving assembly. The conveying assembly extends at least partially into the demolding device, and a base is disposed on the conveying assembly and moves along the conveying direction of the conveying assembly. The product receiving assembly includes a horizontally movable product receiving tray disposed between the demolding frame and the conveying assembly.

[0023] As can be seen from the above scheme, the conveying component is used to automatically convey and remove the mold to the demolding device; the product receiving tray is used to move to the bottom of the product during the ejection process to receive the product after demolding.

[0024] To achieve the second objective mentioned above, the present invention provides a continuous production system including the demolding device described above. Attached Figure Description

[0055] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0056] Example of a demolding device:

[0057] See Figure 1 and Figure 2 and combined Figure 12 The demolding device 100 provided in this embodiment includes a fixed frame 1, a first lifting component 2, a second lifting component 3, a base 4, a conveying component (not shown in the figure), and a product receiving component 5.

[0058] The first lifting assembly 2 is located at the lower part of the fixed frame 1. The first lifting assembly 2 includes a demolding support 21, a first lifting drive device 22, a mounting frame 23, two first lifting frames 24, and four buffer assemblies 25. The two first lifting frames 24 are arranged opposite to each other, and the two sides of the mounting frame 23 are respectively connected to the two first lifting frames 24. The demolding support 21 is mounted on the mounting frame 23. The first lifting drive device 22 is preferably a motor. The first lifting drive device 22 drives the two first lifting frames 24 to move up and down synchronously through a screw transmission mechanism, thereby driving the demolding support 21 to move up and down. The buffer assemblies 25 are connected between the demolding support 21 and the mounting frame 23. Preferably, the four buffer assemblies 25 are respectively connected to the lower side of the four corners of the demolding support 21, so that the demolding support can move elastically up and down relative to the mounting frame 23.

[0059] The second lifting assembly 3 is disposed on the upper part of the fixed frame 1. The second lifting assembly 3 includes a demolding frame 31, a second lifting drive device 32, and two second lifting frames 33. The two second lifting frames 33 are arranged opposite to each other, and the two sides of the demolding frame 31 are respectively connected to the two second lifting frames 33. The second lifting drive device 32 is preferably a motor. The second lifting drive device 32 drives the two second lifting frames 33 to move up and down synchronously through a screw transmission mechanism, thereby driving the demolding frame 31 to move up and down.

[0060] The conveying component extends at least partially into the demolding device 100, preferably penetrating the demolding device 100 in the front-to-back direction, so that the mold 6 can enter from one side of the demolding device 100 and exit from the other side after demolding.

[0061] The base 4 is mounted on the conveying assembly and moves along the conveying direction of the conveying assembly. The mold 6 is mounted on the base 4 and moves with the base 4. The base 4 and the mold 6 on it are both positioned between the demolding support 21 and the demolding frame 31.

[0062] The product receiving assembly 5 includes a product receiving conveyor frame 51 and a product receiving tray 52. ​​The conveying part of the product receiving conveyor frame 51 is located above the conveying assembly and below the demolding frame 31. The product receiving tray 52 is horizontally movable on the conveying part, so that the product receiving tray 52 can move horizontally between the demolding frame 31 and the conveying assembly, which facilitates receiving the product during demolding.

[0063] See Figure 3 and Figure 4 The demolding frame 31 is provided with an ejector plate 34 and an ejector drive assembly 35. The ejector plate 34 is disposed inside the demolding frame 31, and the ejector drive assembly 35 is disposed on the upper part of the demolding frame 31. The ejector drive assembly 35 can drive the ejector plate 34 to move up and down inside the demolding frame 31.

[0064] The ejection drive assembly 35 includes a first drive device 351, a transmission assembly 352, four sleeves 353, four drive rods 354, and four sliding members 355.

[0065] A sleeve 353 is disposed on the top of the demolding frame 31, and the drive rod 354 and the sliding member 355 are both disposed within the sleeve 353. The first end of the sliding member 355 is connected to the drive rod 354, and the second end of the sliding member 355 extends through the top wall of the demolding frame 31 into the interior of the demolding frame 31 and is connected to the ejector plate 34. The first drive device 351 is preferably a motor, the drive rod 354 is a lead screw, and the sliding member 355 is a sliding sleeve. A first nut is disposed within the first end of the sliding sleeve, and the lead screw is inserted into the sliding sleeve and is connected to the first nut for transmission. The first drive device 351 simultaneously drives the four drive rods 354 to rotate via the transmission assembly 352, thereby causing the four sliding members 355 and the ejector plate 34 to move up and down.

[0066] See Figures 5 to 7 and combined Figure 3 and Figure 4 The base 4 includes a first base 41 and a second base 42, with the second base 42 detachably mounted on the first base 41. The first base 41 has four lower mold support portions 411 and four connecting holes 412, with each lower mold support portion 411 corresponding to one of the connecting holes 412. Each connecting hole 412 passes through the middle of the lower mold support portion 411. The second base 42 has four upper mold support portions 421 and four clearance holes 422, with each clearance hole 422 corresponding to and connecting to one of the connecting holes 412. The upper mold support portions 421 correspond to the lower mold support portions 411. Both the lower mold support portions 411 and the upper mold support portions 421 are located within the demolding frame 31 and below the ejector plate 34. The second base 42 is detachably connected to the demolding frame 31 and moves with it.

[0067] Four molds 6 are provided on the base 4, and the four molds 6 are correspondingly arranged with four connecting holes 412. Each mold 6 includes an upper mold 61 and a lower mold 62. The upper mold 61 is set on the upper mold support part 421 and can move up and down with the second base 42. The lower mold 62 is fixedly set on the lower mold support part 411 and extends upward through the corresponding clearance hole 422 into the upper mold 61. A molding cavity is formed between the upper mold 61 and the lower mold 62. When the mold is opened, the second base 42 and the upper mold 61 on it can move with the demolding frame 31. In this embodiment, the upper mold 61 is the female mold and the lower mold 62 is the male mold. When the upper mold 61 and the lower mold 62 are separated, the product is located in the upper mold 61.

[0068] Each upper mold 61 has multiple first air holes (not shown in the figure), multiple ejector assemblies 611, and multiple filling nozzle assemblies 63 on its top. The multiple first air holes are evenly distributed on the outer peripheral wall of the upper mold 61, penetrating the outer peripheral wall and communicating with the molding cavity. The diameter of the first air holes is small, preventing material filling the molding cavity from entering the first air holes. The ejector assemblies 611 are located below the ejector plate 34. Each ejector assembly 611 includes an ejector rod 6111 and a second elastic member 6113. The first end of the ejector rod 6111 has a pushing part 61111 for direct contact with the product, and the second end of the ejector rod 6111 is connected to a second nut 6112. The top wall of the upper mold 61 has a mounting hole 613, through which the ejector rod 6111 passes, and the pushing part 61111 extends into the molding cavity. The second elastic member 6113 elastically abuts against the second nut 6112 and the top wall of the upper mold 61.

[0069] When ejecting the product, the ejector plate 34 moves downward and pushes the ejector rod 6111 and the second nut 6112 downward. The pushing part 61111 pushes the product downward, causing the product to separate from the upper mold 61, thus achieving demolding. During this period, the second elastic element 6113 is compressed. After demolding is completed, the ejector plate 34 rises, and under the rebound force of the second elastic element 6113, the ejector rod 6111 automatically returns to its initial position, waiting for the next ejection operation.

[0070] The filling nozzle assembly 63 is located at the feed inlet of the mold 6, and the feed inlet of the mold 6 can be opened or closed by an external filling gun. The top of the filling nozzle assembly 63 is lower than the top of the ejector rod 6111 to prevent the ejector plate 34 from colliding with the filling nozzle assembly 63.

[0071] To facilitate product demolding, the demolding frame 31 in this embodiment is designed as a downward-opening cover structure. The lower perimeter of the demolding frame 31 is sealed to the surface of the second base 42, forming a sealed cavity. Since the perimeter of the upper mold 61 is also sealed to the surface of the second base 42, the cavity remains sealed when the demolding frame 31 drives the second base 42 and the upper mold 61 on it to rise.

[0072] The demolding frame 31 is connected to an air inlet pipe 311. One end of the air inlet pipe 311 is connected to the cavity, and the other end of the air inlet pipe 311 is connected to an external air source through a pipe for injecting compressed air into the cavity. During the process of the ejector plate 34 pushing the ejector assembly 611 downward, since the upper mold 61 has multiple first air holes, compressed air can enter the gap between the upper mold 61 and the product through the first air holes, using air pressure to assist demolding.

[0073] See Figures 8 to 11 A plurality of first locking components are connected between the first base 41 and the second base 42. The first locking components include a plurality of first locking components 7a and a plurality of first locking components 7b. The first locking components 7a and the first locking components 7b are respectively disposed around the first base 41 and the second base 42.

[0074] Several first locking components 7a are respectively disposed on both sides of the second base 42 in the width direction. Each first locking component 7a includes a fixed base 71a, a locking element 72a, a first elastic element 73a, and a sliding block 74a. One of the fixed base 71a and the locking element 72a is disposed on the first base 41, and the other is disposed on the second base 42. The fixed base 71a is provided with a locking groove 711, an unlocking groove 712, and a sliding groove 713, the sliding groove 713 communicating with both the locking groove 711 and the unlocking groove 712. The sliding block 74a is disposed within the sliding groove 713, and the sliding block 74a is provided with a recess 741, a first protrusion 742, and a second protrusion 743, the recess 741 being disposed between the first protrusion 742 and the second protrusion 743. The locking element 72a is detachably disposed within the locking groove 711 and the recess 741. The locking element 72a can engage with the first protrusion 742 to restrict the separation of the locking element 72a from the fixed base 71a, that is, to restrict the separation of the first base 41 and the second base 42. The first elastic element 73a elastically abuts against the end of the sliding block 74a and the groove wall of the sliding groove 713, so that the sliding block 74a can slide within the sliding groove 713.

[0075] Several first locking components 7b are respectively disposed on both sides of the second base 42 along its length. Each first locking component 7b includes a fixed base 71b, a locking element 72b, a first elastic element 73b, and a sliding block 74b. The connection relationship between the fixed base 71b, the locking element 72b, the first elastic element 73b, and the sliding block 74b is the same as that in the first locking component 7a, and will not be repeated here. The fixed base 71b is disposed within a through hole in the first base 41, and the locking element 72b is disposed on the side wall of the second base 42 along its length.

[0076] The demolding frame 31 is equipped with several first unlocking components, including a first unlocking component 8a and a first unlocking component 8b. The first unlocking component 8a corresponds one-to-one with the first locking component 7a, and can force the first locking component 7a to unlock. Similarly, the first unlocking component 8b corresponds one-to-one with the first locking component 7b, and can force the first locking component 7b to unlock. Specifically, the first unlocking component can be inserted into the corresponding unlocking slot 712. The first unlocking component abuts against the second protrusion 743 and pushes the first protrusion 742 away from the locking slot 711, causing the locking component 72a to separate from the first protrusion 742, or causing the locking component 72b to separate from the corresponding first protrusion 742, thus achieving unlocking.

[0077] The first unlocking component 8a is directly connected to the demolding frame 31, and automatically inserts into the unlocking slot 712 as the demolding frame 31 moves downward. Figure 11 As shown. The first unlocking component 2 8b includes a cylinder 81 and an unlocking block 82 connected to the drive end of the cylinder 81. The cylinder 81 is connected to the side wall of the demolding frame 31. The cylinder 81 drives the unlocking block 82 to move downward and insert it into the unlocking slot 712, as shown. Figure 12 As shown.

[0078] See Figure 3 To ensure that the demolding frame 31 can lift the second base 42, in this embodiment, a plurality of second locking components 9 are connected between the demolding frame 31 and the second base 42. The plurality of second locking components 9 are respectively disposed around the second base 42 and the demolding frame 31. The structure of the second locking components 9 is similar to that of the first locking components, except that one of the fixing seat and the locking fastener of the second locking component 9 is disposed on the second base 42, and the other is disposed on the demolding frame 31. In this embodiment, it is preferred that the fixing seat is disposed on the second base 42 and the locking fastener is disposed on the demolding frame 31.

[0079] The demolding frame 31 is also provided with several second unlocking components 10, which are arranged one-to-one with the second locking components 9. The second unlocking components 10 can force the second locking components 9 to unlock. The second unlocking component 10 includes a cylinder and an unlocking block connected to the cylinder drive end. The cylinder is connected to the side wall of the demolding frame 31. The cylinder drives the unlocking block to move downward and insert it into the unlocking slot of the second locking component 9, which facilitates the separation of the demolding frame 31 and the second base 42 after demolding.

[0080] Combination Figure 3 , Figures 8 to 10 In order to prevent the second base 42 from falling off accidentally during the mold opening process, the demolding frame 31 of this embodiment is provided with a number of reinforcing components 20, which are respectively arranged on opposite sides of the demolding frame 31.

[0081] The first base 41 has first through holes 413 on opposite sides, and the second base 42 has second through holes 423 on opposite sides. The second through holes 423 are vertically connected to the first through holes 413, and the first through holes 413, the second through holes 423, and the reinforcing component 20 are arranged in a one-to-one correspondence. The second through holes 423 have two unequal hole widths. Preferably, the second through holes 423 are rectangular holes, and the length of the rectangular hole is greater than the width of the rectangular hole.

[0082] The reinforcement component 20 includes a rotary drive device 201 and a reinforcement hook 202. The reinforcement hook 202 is designed with an inverted T-shaped structure. The lower part of the reinforcement hook 202 is provided with two receiving parts 2021. The two receiving parts 2021 are arranged along a straight line, and the longest distance between the two receiving parts 2021 is slightly less than the length of the second through hole 423 and greater than the width of the second through hole 423.

[0083] In the initial state, the two receiving parts 2021 are parallel to the length direction of the second through hole 423, allowing the reinforcing hook 202 to pass through the second through hole 423 and extend into the first through hole 413. When the demolding frame 31 drives the second base 42 to rise to a preset height, the rotary drive device 201 can drive the reinforcing hook 202 to rotate by a preset angle, preferably 90°, so that the two receiving parts 2021 are parallel to the width direction of the second through hole 423, and the receiving parts 2021 abut against the bottom wall of the second base 42 to hook the second base 42 and prevent the second base 42 from accidentally falling.

[0085] See Figure 13 The continuous production system provided in this embodiment includes a conveying device 200, a heating device 300, a cooling device 400, a filling device 500, and a demolding device 100 as described in the previous embodiment. The filling device 500, heating device 300, cooling device 400, and demolding device 100 are all located within the conveying range of the conveying device 200. The base 4 and the mold 6 are both mounted on the conveying device 200 and can move along the conveying direction of the conveying device 200 to sequentially enter the filling device 500, heating device 300, cooling device 400, and demolding device 100, and are thus cyclically conveyed. The conveying device 200 is connected to the conveying assembly of the demolding device 100, allowing the base 4 and the mold 6 on it to be transferred between the conveying device 200 and the conveying assembly. Alternatively, the conveying assembly of the demolding device 100 is part of the conveying device 200.

[0086] The conveying route of the conveying device 200 is set to a closed loop or a linear loop to realize the function of cyclic conveying and ensure continuous molding production of products.

[0087] The closed-loop type in this embodiment is a rectangular loop type. The conveying device 200 includes four conveyor frames 2001 and four transplanters 2002. The four conveyor frames 2001 are connected end to end and arranged in a rectangle. The transplanter 2002 is set at the connection between two adjacent conveyor frames 2001 and is used to transfer the base 4 and the mold 6 on the previous conveyor frame 2001 to the next conveyor frame 2001.

[0088] In another embodiment, the closed-loop type is a circular loop type. The conveying device includes a turntable that can rotate around its own axis. A filling device, a heating device, a cooling device and a demolding device are arranged in sequence around the turntable. Multiple bases and the molds on them are set on the turntable and rotate with it.

[0089] In another embodiment, the conveying route of the conveying device is set as a linear circulation type. The conveying device includes two conveying frames and two elevators. The two conveying frames are arranged vertically, and the two elevators are respectively located at both ends of the conveying frames. The filling frame moves vertically between the two conveying frames to realize the cyclical movement of the base and the mold on it between the upper and lower conveying frames.

[0090] In summary, the demolding support 21 of the present invention is used to lift the base 4 and the mold 6 on it, so that the base 4 is temporarily separated from the conveying surface of the conveying component, which facilitates the mold opening and demolding operations. It is especially suitable for continuous production methods in which the mold 6 is continuously conveyed by the conveying component. The lower mold 62 of the mold 6 is set on the first base 41, and the upper mold 61 of the mold 6 is set on the second base 42, and the second base 42 can be connected to the demolding frame 31. When the mold is opened, the demolding frame 31 drives the second base 42 and the upper mold 61 to move upward, completing the mold opening of the mold 6. At this time, the product is left in the upper mold 61. The upper mold 61 is provided with an ejection component 611. The ejection drive component 35 drives the ejection plate 34 to move downward, so that the ejection component 611 ejects the product downward, thereby realizing demolding. The present invention can perform mold opening and demolding operations sequentially on the mold 6 that is conveyed to the demolding station. It has the advantages of simple structure, convenient operation and suitability for continuous production.

[0091] Finally, it should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
