Description

Technical Field

[0001] The invention relates to the technical field of cabinet molding production equipment, and in particular to an automated mold system for a foaming cabinet. Background Art

[0002] The box shells of existing refrigeration and heat preservation equipment such as commercial freezers and household refrigerators are usually foam boxes, which have good heat preservation effects. The manufacturing process of the foam box is roughly as follows: a thin metal sheet is bent to form a temporary box structure with a hollow cavity, that is, the box plate of the box of the temporary box structure is a hollow structure, and then the hollow cavity of the temporary box structure is filled with foam material. After the foam material in the hollow cavity is hardened, a foam box is formed. In the production process, in order to prevent the temporary box structure from being deformed when the foam material is filled and ensure that the box shape is regular, it is often necessary to use a corresponding foam box mold when filling the foam, and wrap and support the inside and outside of the temporary box structure, so as to support and limit the shape of the temporary box structure;

[0003] The existing foaming box mold is composed of a core mold module that supports the interior of the temporary box structure and a cavity mold module that limits the external shape of the temporary box. In actual use, when each cavity mold module is unfolded, the temporary box structure is placed in the cavity mold, and then the core mold module is covered with the cavity mold to complete the mold closing. When the foaming material needs to be filled and taken out, the cavity mold module is unfolded again, and then the core mold module is taken out.

[0004] However, the above method has the disadvantage that when the box is large, the temporary box structure needs to be assisted by corresponding lifting equipment during the process of being placed into the mold cavity. The temporary box structure that is easily deformed has high requirements on the lifting equipment, which makes it inconvenient to take and place the temporary box structure in the foaming box mold. In order to solve the above problem, we propose an automated foaming box mold system. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-8 , an embodiment of the present invention provides an automated mold system for a foaming box, comprising a support frame 1 with a core mold installed on the top, a bottom template 2 that can reciprocate in its vertical direction is installed on the support frame 1, left and right template units 3 that constitute a mold cavity are arranged on both sides of the bottom template 2, and front and rear template units 4 that constitute a mold cavity are arranged on the top of the support frame 1. When the bottom template 2 is at the highest position on its stroke, the bottom template 2, the left and right template units 3, and the front and rear template units 4 can form a closed mold cavity structure adapted to a temporary box structure with the core mold, and the bottom template 2 can be connected to a material conveying line at the lowest position on its stroke;

[0031] Specifically, the support frame 1 includes an upper frame located at the top and a lower frame located on the ground. The corners of the upper frame and the lower frame are connected and fixed by frame columns. A top plate is fixed on the frame mouth surface of the upper frame. A core mold module is fixed below the top plate. The core mold module is filled and adapted with the internal space of the temporary box structure. The support frame 1 is a rectangular box frame structure as a whole. The plate surface of the bottom template 2 is parallel to the horizontal plane. During the lifting process of the bottom template 2, the plate surfaces of the left and right side template units 3 are perpendicular to the plate surface of the bottom template 2, and the plate surfaces of the front and rear side template units 4 can be perpendicular to the plate surfaces of the left and right side template units 3.

[0032] In actual use, when the bottom template 2 is able to connect with the material conveying line at the lowest position in its stroke, the material conveying line will transfer the temporary box structure to the bottom template 2, and the temporary box structure will rise synchronously with the rise of the bottom template 2. When the bottom template 2 reaches the highest position, the temporary box structure is located in the closed mold cavity structure composed of the bottom template 2, the left and right side template units 3, the front and rear side template units 4 and the core mold, thereby completing the mold closing of the temporary box structure. When the temporary box structure needs to complete filling and molding, the bottom template 2 returns to the lowest position and then re-connects with the material conveying line to complete the unloading. During the whole process, there is no need to use lifting equipment for auxiliary hanging, which is beneficial to prevent abnormal deformation of the temporary box structure. The process is simple to operate and can achieve coordinated action with the material conveying line to improve production efficiency.

[0033] In another embodiment provided by the present invention, a lifting mechanism 5 is installed on the support frame 1, and the lifting mechanism 5 includes a supporting frame 5.1 fixed to the bottom template 2, and the frame opening surface of the supporting frame 5.1 is parallel to the horizontal plane. The supporting frame 5.1 is connected to the support frame 1 through a plurality of hydraulic lifting columns 5.2. Preferably, the hydraulic lifting columns 5.2 can also be replaced by a servo motor fixed with a threaded column. The lifting mechanism 5 can switch the position of the bottom template 2 on its stroke, wherein a plurality of guide columns fixed to the support frame 1 are movably inserted on the supporting frame 5.1 to keep the supporting frame 5.1 in a horizontal state at all times. In actual use, the supporting frame 5.1 is switched between the highest position and the lowest position through the synchronous extension and contraction of the plurality of hydraulic lifting columns 5.2.

[0034] In another embodiment provided by the present invention, the left and right side template units 3 include two first plate bodies 3.1 symmetrically located on both sides of the bottom template 2, the first plate bodies 3.1 are hinged to the supporting frame 5.1, specifically, a connecting plate 3.3 is fixed to the back of the first plate body 3.1, the bottom end of the connecting plate 3.3 is hinged to the supporting frame 5.1, the connecting plate 3.3 is a long strip plate, the number of connecting plates 3.3 is two, and the bottom template 2 is at the lowest position. The left and right side template units 3 can be in an expanded state. In actual use, when the two first plate bodies 3.1 deflect in opposite directions, such as when the angle between the first plate body 3.1 and the upper frame surface of the supporting frame 5.1 is 110 degrees, the left and right side template units 3 are in an expanded state. When the bottom template 2 leaves the lowest position, the angle between the first plate body 3.1 and the upper frame surface of the supporting frame 5.1 is 90 degrees. At this time, the left and right side template units 3 are in a retracted state, and the plate surfaces between the two first plate bodies 3.1 are parallel to each other;

[0035] In actual use, when the bottom template 2 is in the lowest position, the left and right side template units 3 are in an expanded state, so as to facilitate the acceptance of the temporary box structure or the transfer of the formed temporary box structure to the material conveying line. When the bottom template 2 leaves the lowest position, the left and right side template units 3 are always in a retracted state, so as to maintain support for the temporary box structure. When the bottom template 2 reaches the highest position, the first plate body 3.1 is in vertical contact with the template on the core mold, and the bottom template 2, the left and right side template units 3, the front and rear side template units 4 and the core mold form a closed mold cavity structure.

[0036] In another embodiment provided by the present invention, both sides of the bottom template 2 are provided with a transport mechanism 6 movably mounted on the support frame 5.1, each transport mechanism 6 includes a mounting plate 6.1 vertically clamped with the inner wall surface of the support frame 5.1, the mounting plate 6.1 can move in its vertical direction, and a first wheel set 6.2 and a second wheel set 6.3 are rotatably mounted on the plate body of the mounting plate 6.1, and the first wheel set 6.2 and the second wheel set 6.3 are connected by a transmission chain 6.4, wherein the first wheel set 6.2 and the second wheel set 6.3 are both rotatably mounted Installed on the side of the mounting plate 6.1 facing the bottom template 2, the first wheel set 6.2 and the second wheel set 6.3 are both composed of a plurality of rotating wheel units arranged linearly, and the rotating wheel unit includes a wheel shaft fixed vertically to the mounting plate 6.1, wherein a rubber wheel 14 is rotatably mounted on the wheel shaft of the first wheel set 6.2, and a chain plate 15 meshing with the transmission chain 6.4 is fixed on the side of the rubber wheel, and a first gear 16 is rotatably mounted on the wheel shaft of the first wheel set 6.2, and a chain plate 15 meshing with the transmission chain 6.4 is fixed on the side of the first gear 16;

[0037] In actual use, when the first gear 16 rotates, under the transmission action of the transmission chain 6.4 and the chain plate 15, the first wheel group 6.2 and the second wheel group 6.3 rotate synchronously. It should be noted that in this state, the top surfaces of the multiple rubber wheels 14 are higher than the top surface of the bottom template 2, so that the first wheel group 6.2 lifts the temporary box structure, so that the bottom surface of the temporary box structure and the top surface of the bottom template 2 are in a phase-separated state. At the same time, the first wheel group 6.2 moves the temporary box structure parallel to the top surface of the bottom template 2, so as to facilitate the bottom template 2 to be transmitted to the material conveying line, or to receive the temporary box structure from the material conveying line.

[0038] In another embodiment provided by the present invention, the support frame 1 further includes a base block 7, a power unit 8 is fixed on the base block 7, and the power unit 8 can provide support and driving force for the transportation mechanism 6 at the lowest position of the bottom template 2. Specifically, the power unit 8 includes a driving motor 8.1, and a second gear 8.2 that can mesh with the first gear 16 is fixed on the output shaft of the driving motor 8.1. The bottom of the second gear 8.2 is meshed with a supporting gear roller 8.3 rotatably mounted with the base block 7, and the supporting gear roller 8.3 provides vertical support for the second gear 8.2;

[0039] In actual use, as the bottom template 2 approaches the lowest position, when the first gear 16 is in contact and meshing with the second gear 8.2, the mounting plate 6.1 stops moving downward under the support of the second gear 8.2, while the bottom template 2 continues to move downward until it reaches the lowest position. At this time, the top surfaces of the plurality of rubber wheels 14 are all higher than the top surface of the bottom template 2, thereby lifting the temporary box structure relative to the bottom template 2, and the driving motor 8.1 drives the second gear 8.2 to rotate, so that the first gear 16 drives the first wheel group 6.2 to rotate synchronously through the transmission chain 6.4, and the movement direction of the temporary box structure on the bottom template 2 is controlled by controlling the rotation direction of the output shaft of the driving motor 8.1;

[0040] When the bottom template 2 moves toward the highest position, as the bottom template 2 moves upward, the bottom template 2 gradually approaches the bottom of the temporary box structure. When the bottom template 2 contacts and supports the bottom of the temporary box structure and drives the temporary box structure to move upward, the top surface of each rubber wheel 14 is flush with the top surface of the bottom template 2. Each rubber wheel 14 and the bottom template 2 support the bottom of the temporary box structure, and the first gear 16 and the second gear 8.2 are separated.

[0041] In another embodiment provided by the present invention, a supporting unit 17 is provided between the first wheel set 6.2 and the second wheel set 6.3, and the supporting unit 17 includes a fixed block 17.1 fixed to the mounting plate 6.1, a first support wheel 17.2 is rotatably mounted above the fixed block 17.1 and is in rolling contact with the wheel body of the first wheel set 6.2, and a second support wheel 17.3 is rotatably mounted below the fixed block 17.1 and is in rolling contact with the wheel body of the second wheel set 6.3, and the supporting unit 17 plays a rolling support role between the first wheel set 6.2 and the second wheel set 6.3.

[0042] In another embodiment provided by the present invention, each first plate body 3.1 is connected to the mounting plate 6.1 through a locking assembly 9, and the locking assembly 9 includes strips 9.1 located at both ends of the mounting plate 6.1 and fixed to the first plate body 3.1, the length direction line of the strip 9.1 is perpendicular to the plate surface of the first plate body 3.1, and a long strip opening 9.2 is opened on the plate body of the strip 9.1, and the length direction line of the long strip opening 9.2 is parallel to the length direction line of the strip 9.1, and a plug post 9.3 rotatably installed on the end surface of the mounting plate 6.1 is inserted into the long strip opening 9.2, and the axis line of the plug post 9.3 is perpendicular to the plate surface of the strip 9.1;

[0043] In actual use, when the first gear 16 on the mounting plate 6.1 is in meshing contact with the second gear 8.2 on the power unit 8, under the support of the second gear 8.2, the mounting plate 6.1 stops moving downward, while the bottom template 2 and the first plate body 3.1 continue to move downward. At this time, the plug post 9.3 moves relatively forward in the long strip opening 9.2, and the first plate body 3.1 deflects in the direction away from the bottom template 2, thereby realizing that the left and right side template units 3 are in the expanded state until the bottom template 2 reaches the lowest position. Similarly, when the bottom template 2 and the first plate body 3.1 are in the expanded state, the bottom template 2 and the first plate body 3.1 are in the expanded state. When the body 3.1 rises, the plug post 9.3 moves relatively in the opposite direction in the long strip opening 9.2, and the first plate body 3.1 deflects in the direction close to the bottom template 2, so that the left and right side template units 3 are in a retracted state. In summary, under the connection action of the interlocking assembly 9, when the bottom template 2 is in the lowest position, the left and right side template units 3 are in an expanded state, and when the bottom template 2 is in the highest position, the left and right side template units 3 are in a retracted state, so that the states of the left and right side template units 3 can automatically generate corresponding automatic switching according to the changes of the bottom template 2 in different positions.

[0044] In another embodiment provided by the present invention, the width diameter of the strip opening 9.2 is greater than the cross-sectional diameter of the plug post 9.3, a tooth groove structure 9.4 is provided on the inner wall circumferential surface of the strip opening 9.2, and the number of the tooth groove structures 9.4 is multiple, and the multiple tooth groove structures form a tooth surface on the inner wall circumferential surface of the strip opening 9.2, and a tooth ring groove 9.5 that meshes with the tooth groove structure 9.4 is provided on the column body of the plug post 9.3. In actual application, when the tooth ring groove 9.5 meshes with the tooth groove structure 9.4, the inner wall circumferential surface of the strip opening 9.2 and the column body of the plug post 9.3 are in an extrusion state, and when the column body of the plug post 9.3 has a force acting along the length direction line of the strip opening 9.2, the plug post 9.3 rolls relatively on the inner wall circumferential surface of the strip opening 9.2;

[0045] Among them, a swivel column unit 10 is installed at the top of the mounting plate 6.1, and the swivel column unit 10 includes a support rod 10.1 vertically plugged into the top of the mounting plate 6.1, and a roller 10.2 is fixed on the rod body of the support rod 10.1 extending out of the mounting plate 6.1. When the first wheel group 6.2 lifts the temporary box structure relative to the bottom template 2, the roller 10.2 is located at the side of the temporary box structure, which limits the side of the temporary box structure when the bottom template 2 moves horizontally, preventing the temporary box structure from shifting during horizontal movement. It should be particularly noted that a recessed portion 3.2 is provided on the side surface of the bottom end of the first plate body 3.1, so that when the left and right template units 3 are in a retracted state, the recessed portion 3.2 accommodates the swivel column unit 10;

[0046] In addition, an insertion port 11 for the plug post 9.3 to be plugged into is provided at the end of the mounting plate 6.1, an inner ring groove 12 is provided on the inner wall of the insertion port 11, and a ratchet ring 13 fixed to the column of the plug post 9.3 is adapted in the inner ring groove 12. The rotation of the plug post 9.3 and the ratchet ring 13 is synchronous and in the same direction, the support rod 10.1 can contact with the ratchet ring 13, the ratchet ring 13 can only rotate in the same direction, and the support rod 10.1 can move in the direction of the axial center line of the support rod 10.1; therefore, when the ratchet ring 13 rotates clockwise, the bottom end of the support rod 10.1 moves along the ratchet ring 13. The tooth slope slides, so that the support rod 10.1 moves upward in the axial direction. When the support rod 10.1 passes over the ratchet teeth of the ratchet ring 13, the support rod 10.1 drops to the ratchet tooth root position of the ratchet ring 13 under the gravity of the support rod 10.1 and the roller 10.2. When the ratchet ring 13 rotates counterclockwise, the support rod 10.1 located at the ratchet tooth root position of the ratchet ring 13 contacts the right-angle surface of the ratchet teeth of the ratchet ring 13, thereby limiting the reverse rotation of the ratchet ring 13, so that the plug post 9.3 can only rotate clockwise and cannot rotate counterclockwise.

[0047] In actual use, when the bottom template 2 and the first plate body 3.1 descend, so that the first plate body 3.1 deflects in the direction away from the bottom template 2, the plug post 9.3 is squeezed on the upper wall surface of the inner wall circumferential surface of the long strip opening 9.2, and the plug post 9.3 moves relatively positively in the long strip opening 9.2, and the rotation of the plug post 9.3 relative to the mounting plate 6.1 is clockwise; when the bottom template 2 and the first plate body 3.1 rise, so that the first plate body 3.1 deflects in the direction close to the bottom template 2, the plug post 9.3 is squeezed on the lower wall surface of the inner wall circumferential surface of the long strip opening 9.2, and the plug post 9.3 moves relatively reversely in the long strip opening 9.2, and the rotation of the plug post 9.3 relative to the mounting plate 6.1 is still clockwise;

[0048] When the left and right side template units 3 are in the retracted state, if a deflection force is applied to the first plate body 3.1 alone in the direction away from the bottom template 2, the plug post 9.3 is squeezed on the lower wall surface of the inner wall circumferential surface of the long strip opening 9.2, and the plug post 9.3 moves relatively positively in the long strip opening 9.2. Then, the rotation of the plug post 9.3 relative to the mounting plate 6.1 has a counterclockwise rotation trend. Since the plug post 9.3 cannot rotate counterclockwise, it can achieve a locking effect on the left and right side template units 3 in the retracted state. In other words, when the bottom template 2 is out of the lowest position, the interlocking component 9 can switch the left and right side template units 3 from the expanded state to the retracted state, and lock the left and right side template units 3 in the retracted state. When the bottom template 2 is close to the lowest position, the interlocking component 9 can switch the left and right side template units 3 from the retracted state to the expanded state, and unlock the left and right side template units 3 in the retracted state.

[0049] In another embodiment provided by the present invention, the front and rear side template units 4 include two second plate bodies 4.1, and a template plate 4.2 fixed to the support frame 1 is arranged in parallel on the back of each second plate body 4.1, and a plurality of bars 4.3 are hinged on the template plate 4.2, and the other end of each bar 4.3 is hinged to the side of the second plate body 4.1. In actual use, when the second plate body 4.1 has not yet contacted with the bottom template 2, the bottom end of the second plate body 4.1 extends below the template plate 4.2, and the angle between the bar 4.3 and the plate surface of the template plate 4.2 is an acute angle, such as 45 degrees. As the bottom template 2 rises, the second plate body 4.1 is lifted, and at this time, under the support of the bar 4.3, the second plate body 4.1 moves toward the position of the first plate body 3.1 until the bottom template 2 reaches the highest position. The bar 4.3 is perpendicular to the second plate body 4.1, thereby forming a closed mold cavity structure suitable for the temporary box structure together with the first plate body 3.1, the bottom template 2 and the core mold. Similarly, when the bottom template 2 descends, the second plate body 4.1 returns to its initial position under the action of its own gravity. The whole process realizes that the front and rear side template units 4 can adaptively change their positions according to the position change of the bottom template 2, cooperating with the formation and expansion of the closed mold cavity structure.

[0050] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
