Description

Technical Field

[0001] The present invention relates to the technical field of cabinet forming production equipment, and particularly to an automated foam box mold system. Background Art

[0002] The box shells of existing commercial freezers, household refrigerators and other refrigeration and heat preservation equipment are usually foam boxes, so as to have good heat preservation effects. The manufacturing process of the foam box is generally as follows: bending a thin metal sheet to form a temporary box structure with a hollow cavity, that is, the box board of the box of the temporary box structure is a hollow structure, and then filling the hollow cavity of the temporary box structure with a foaming material. After the foaming material in the hollow cavity hardens, a foam box is formed. In production, in order to prevent the temporary box structure from deforming when filling the foaming material and ensure the regular shape of the box, it is often necessary to use a corresponding foam box mold to 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 foam box mold consists of a core mold module for internal support of the temporary box structure and a cavity mold module for restricting the external shape of the temporary box. In actual use, when each cavity mold module is unfolded, the temporary box structure is placed into the cavity mold at this time, and then the core mold module and the cavity mold are covered to complete the mold closing. When it is necessary to take out the foam box after filling the foaming material, the cavity mold module is unfolded again, and then the core mold module can be taken out.

[0004] However, the above method has the following disadvantages: when the size of the box is large, the temporary box structure needs to be assisted by a corresponding hoisting device during the process of being placed into the mold cavity. The easily deformable temporary box structure has high requirements for the hoisting device, which is not convenient for the taking and placing operation of the temporary box structure in the foam box mold. To solve the above problems, we thus propose an automated foam box mold system. Summary of the Invention

Detailed implementation manners

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

[0030] Please refer to Figure 1-8 , an automated mold system for a foamed box body provided by an embodiment of the present invention includes a support frame 1 with a core mold installed on the top, a bottom template 2 installed on the support frame 1 and capable of reciprocating in the vertical direction thereof, left and right side template units 3 forming a mold cavity are arranged on both sides of the bottom template 2, front and rear side template units 4 forming a mold cavity are arranged on the top of the support frame 1. When the bottom template 2 is at the highest position in its stroke, the bottom template 2, the left and right side template units 3, and the front and rear side template units 4 can form a closed mold cavity structure adapted to the temporary box body structure with the core mold. When the bottom template 2 is at the lowest position in its stroke, it can be docked with the material conveying line;

[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 driving action of the transmission chain 6.4 and the chain wheel 15 at this time, the first wheel set 6.2 and the second wheel set 6.3 rotate synchronously. It should be particularly noted that in this state, the top surfaces of the multiple rubber wheels 14 are all higher than the top surface of the bottom template 2. Thus, the first wheel set 6.2 lifts the temporary box structure, making the bottom surface of the temporary box structure separated from the top surface of the bottom template 2. At the same time, the first wheel set 6.2 moves the temporary box structure parallel on the top surface of the bottom template 2, facilitating the transfer of the bottom template 2 to the material conveying line or receiving 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. The power unit 8 can provide a supporting force and a driving force for the transportation mechanism 6 at the lowest position of the stroke of the bottom template 2. Specifically, the power unit 8 includes a driving motor 8.1. 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. A supporting gear roller 8.3 rotatably installed on the base block 7 meshes with the bottom of the second gear 8.2. The supporting gear roller 8.3 provides a supporting force for the second gear 8.2 in the vertical direction.

[0039] During actual use, as the bottom template 2 approaches the lowest position, when the first gear 16 comes into contact and meshes with the second gear 8.2, under the supporting action of the second gear 8.2 at this time, the mounting plate 6.1 stops moving downward, while the bottom template 2 continues to move downward until it reaches the lowest position. At this time, the top surfaces of the multiple rubber wheels 14 are all higher than the top surface of the bottom template 2, thus lifting the temporary box structure relative to the bottom template 2. The driving motor 8.1 drives the second gear 8.2 to rotate, so that the first gear 16 drives the first wheel set 6.2 to rotate synchronously through the transmission chain 6.4. The moving 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 towards 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, at this time, the top surfaces of the respective rubber wheels 14 are flush with the top surface of the bottom template 2. Each rubber wheel 14 and the bottom template 2 both play a supporting role for the bottom of the temporary box structure, and the first gear 16 and the second gear 8.2 are separated.

[0041] In yet 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. The supporting unit 17 includes a fixed block 17.1 fixed to the mounting plate 6.1. Above the fixed block 17.1, a first supporting wheel 17.2 that is in rolling contact with the wheel body of the first wheel set 6.2 is rotatably mounted. Below the fixed block 17.1, a second supporting wheel 17.3 that is in rolling contact with the wheel body of the second wheel set 6.3 is rotatably mounted. The supporting unit 17 plays a role of rolling support between the first wheel set 6.2 and the second wheel set 6.3.

[0042] In yet another embodiment provided by the present invention, each first plate body 3.1 and the mounting plate 6.1 are connected by a chain component 9. The chain component 9 includes strip plates 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 plate 9.1 is perpendicular to the plate surface of the first plate body 3.1. A long slot 9.2 is formed in the plate body of the strip plate 9.1. The length direction line of the long slot 9.2 is parallel to the length direction line of the strip plate 9.1. An insertion post 9.3 rotatably mounted on the end surface of the mounting plate 6.1 is inserted into the long slot 9.2. The axis line of the insertion post 9.3 is perpendicular to the plate surface of the strip plate 9.1.

[0043] During 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 supporting action of the second gear 8.2, at this time, the mounting plate 6.1 stops moving downward, while the bottom template 2 and the first plate body 3.1 still continue to move downward. At this time, the insertion post 9.3 moves relatively forward in the long slot 9.2, and the first plate body 3.1 deflects in a direction away from the bottom template 2, so as to realize the unfolded state of the left and right side template units 3 until the bottom template 2 reaches the lowest position. Similarly, when the bottom template 2 and the first plate body 3.1 rise, at this time, the insertion post 9.3 moves relatively backward in the long slot 9.2, and at this time, the first plate body 3.1 deflects in a direction close to the bottom template 2, so as to realize the folded state of the left and right side template units 3. In summary, under the connection action of the chain component 9, when the bottom template 2 is at the lowest position, the left and right side template units 3 are in the unfolded state, and when the bottom template 2 is at the highest position, the left and right side template units 3 are in the folded state, so that the state of the left and right side template units 3 can automatically switch accordingly according to the change of the bottom template 2 at different positions.

[0044] In yet another embodiment provided by the present invention, the width diameter value of the long strip opening 9.2 is greater than the cross-sectional diameter value of the insertion post 9.3. A tooth groove structure 9.4 is provided on the circumferential surface of the inner wall of the long strip opening 9.2. The number of the tooth groove structures 9.4 is multiple. The multiple tooth groove structures form a tooth surface on the circumferential surface of the inner wall of the long strip opening 9.2. A tooth ring groove 9.5 that is meshed and matched with the tooth groove structure 9.4 is provided on the column body of the insertion post 9.3. In practical applications, when the tooth ring groove 9.5 is meshed with the tooth groove structure 9.4, the circumferential surface of the inner wall of the long strip opening 9.2 and the column body of the insertion post 9.3 are in a squeezing state. When there is a force along the length direction line of the long strip opening 9.2 on the column body of the insertion post 9.3, the insertion post 9.3 rolls relatively on the circumferential surface of the inner wall of the long strip opening 9.2;

[0045] Wherein, a rotation blocking post unit 10 is installed at the top end of the mounting plate 6.1. The rotation blocking post unit 10 includes a support rod 10.1 vertically inserted into the top end of the mounting plate 6.1. 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 set 6.2 lifts the temporary box structure relative to the bottom template 2, at this time, the roller 10.2 is located on the side surface of the temporary box structure, playing a limiting role in the side surface of the temporary box structure during the horizontal movement on the bottom template 2, preventing the temporary box structure from shifting during the horizontal movement. It should be particularly noted that a recess 3.2 is provided on the bottom side surface of the first plate body 3.1, so that when the left and right side template units 3 are in a retracted and combined state, the recess 3.2 houses the rotation blocking post unit 10;

[0046] In addition, an insertion opening 11 for the insertion post 9.3 to be inserted 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 opening 11. A ratchet ring 13 fixed to the column body of the insertion post 9.3 is fitted in the inner ring groove 12. The rotation of the insertion post 9.3 and the ratchet ring 13 is synchronous and in the same direction. The support rod 10.1 can contact the ratchet ring 13. The ratchet ring 13 can only rotate in the same direction. The support rod 10.1 can move in the axial direction of the support rod 10.1; Therefore, when the ratchet ring 13 rotates clockwise, at this time, the bottom end of the support rod 10.1 slides along the inclined surface of the ratchet teeth of the ratchet ring 13, so that the support rod 10.1 moves upward in the axial direction. When the support rod 10.1 crosses the ratchet teeth of the ratchet ring 13, at this time, under the gravity of the support rod 10.1 and the roller 10.2, the support rod 10.1 descends again to the root position of the ratchet teeth of the ratchet ring 13; When the ratchet ring 13 rotates counterclockwise, at this time, the support rod 10.1 located at the root position of the ratchet teeth of the ratchet ring 13 contacts the right-angle surface of the ratchet teeth of the ratchet ring 13, thereby restricting the reverse rotation of the ratchet ring 13, so that the insertion post 9.3 can only rotate clockwise and cannot rotate counterclockwise;

[0047] During actual use, when the bottom formwork 2 and the first plate body 3.1 descend, causing the first plate body 3.1 to deflect away from the bottom formwork 2, at this time, the insertion post 9.3 is squeezed against the upper wall surface of the circumferential surface of the inner wall of the long slot 9.2, and the insertion post 9.3 moves relatively forward within the long slot 9.2, and the rotation of the insertion post 9.3 relative to the mounting plate 6.1 is clockwise; when the bottom formwork 2 and the first plate body 3.1 ascend, causing the first plate body 3.1 to deflect towards the bottom formwork 2, at this time, the insertion post 9.3 is squeezed against the lower wall surface of the circumferential surface of the inner wall of the long slot 9.2, and the insertion post 9.3 moves relatively backward within the long slot 9.2, and the rotation of the insertion post 9.3 relative to the mounting plate 6.1 is still clockwise;

[0048] When the left and right side formwork units 3 are in the retracted and combined state, if a deflecting force is applied to the first plate body 3.1 alone in the direction away from the bottom formwork 2 at this time, the insertion post 9.3 is squeezed against the lower wall surface of the circumferential surface of the inner wall of the long slot 9.2, and the insertion post 9.3 moves relatively forward within the long slot 9.2. Then, the rotation of the insertion post 9.3 relative to the mounting plate 6.1 has a counterclockwise rotation tendency. Since the insertion post 9.3 cannot rotate counterclockwise, it can lock the left and right side formwork units 3 in the retracted and combined state. In other words, when the bottom formwork 2 leaves the lowest position, the interlocking assembly 9 can switch the left and right side formwork units 3 from the deployed state to the retracted and combined state, and lock the left and right side formwork units 3 in the retracted and combined state. And when the bottom formwork 2 approaches the lowest position, the interlocking assembly 9 can switch the left and right side formwork units 3 from the retracted and combined state to the deployed state, and unlock the left and right side formwork units 3 in the retracted and combined 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. On the back surface of each second plate body 4.1, a die carrier plate 4.2 fixed to the support frame 1 is arranged in parallel. A plurality of strip bars 4.3 are hinged on the die carrier plate 4.2, and the other ends of the strip bars 4.3 are hinged to the side surfaces of the second plate bodies 4.1 respectively. During actual use, when the second plate body 4.1 has not yet contacted the bottom template 2, the bottom end of the second plate body 4.1 extends below the die carrier plate 4.2 at this time, and the included angle between the strip bar 4.3 and the plate surface of the die carrier 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. At this time, under the support of the strip bar 4.3, the second plate body 4.1 tends to move closer to the position where the first plate body 3.1 is located. Until the bottom template 2 reaches the highest position, the strip bar 4.3 is perpendicular to the second plate body 4.1, so as to form a closed die cavity structure adapted to 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 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, and cooperate with the formation and expansion of the closed die cavity structure.

[0050] Some exemplary embodiments of the present invention have been described only by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different 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 protection scope of the claims of the present invention.
