Description

Technical Field

[0001] The invention relates to the technical field of foaming molds, in particular to a foaming mold and a foaming method for an ultra-soft foaming material. Background Art

[0002] Foaming materials are a type of material that introduces gas through physical or chemical methods to form a large number of bubble structures in a polymer matrix. They have the characteristics of light weight, heat insulation, sound insulation, and cushioning, and are widely used in construction, packaging, automobiles, homes and other fields.

[0003] When using foam materials to produce finished products, the foam materials will first be processed, such as heating and melting and injecting a foaming agent. The processed foam material is then poured into the mold through an external injection machine, so that the raw material foams and expands in the mold cavity to produce the foamed finished product.

[0004] When shaping foam materials, existing molds need to first inject the processed foam material into the mold through an injection machine, and then close the mold to allow the material to expand and shape in the mold. However, when processing the foam material, different materials require different processed and added materials, which makes the foam material expand at different speeds. When closing the mold, the mold structure needs to be closed first, and then fixed and closed by multiple locks or connectors, and the operation process takes some time. If a foam material with a faster expansion speed is shaped, it is easy for the connectors or locks to not be fully locked, resulting in insufficient closure of the mold structure, which in turn causes the material to overflow during the operation, which is not conducive to shaping production.

[0018] To achieve the above object, the present invention provides the following technical solution: a foaming method of a foaming mold for an ultra-soft foaming material, comprising the following steps:

[0019] S1: Pour the foaming material into the lower template, then manually pull the upper template and gradually fit it with the lower template, so that the elastic buckle group is inserted into the slot. When the upper template is pulled, the bracket is driven to move, so that the bracket drives the driving member, so that the driving member releases the buckle connection with the extrusion member. Then, the extrusion member squeezes the elastic buckle group, so that the elastic buckle group is engaged with the slot, and the lower template and the upper template are closed.

[0020] S2: When the driving member is driven, the sealing member is driven to move toward the upper template, thereby forming a seal at the gap between the lower template and the upper template;

[0021] S3: After the lower template and the upper template are closed, the foam material expands inside the lower template and expands and shapes along the internal structure of the lower template. After the foam material is completely shaped, the upper template can be opened and demoulded;

[0023] S5: Afterwards, the upper template is opened while the toggle member is kept in the screwed state, and then the toggle member can be released. When opened, the reset member can pull the cutting member to reset. At this time, the driving member is re-connected with the extrusion member, and then the shaped finished product can be taken out from the lower template.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention manually flips the upper template so that the lower template and the upper template are closed. When the upper template rotates, it drives the bracket to operate, so that the internal components of the bracket gradually move toward the direction of the driving member. When the lower template and the upper template are about to form a closed state, the elastic buckle group enters the inner groove. At the same time, the bracket drives the driving member so that the internal components of the driving member release the buckling restriction on the extrusion member, thereby triggering the internal components of the extrusion member, so that the internal components of the extrusion member top-extrude the elastic buckle group, so that the elastic buckle group is deformed and forms a buckling connection with the inner wall of the slot, thereby realizing the closed connection between the lower template and the upper template. The operation is simple, and when the lower template and the upper template are closed, they can be quickly closed and locked, thereby realizing the closed self-locking function, reducing the time spent on manually locking the mold, avoiding the possibility of foam material expansion and overflow during the closing and locking process of the mold, improving the quality of injection molding, and thus improving the quality of the finished product;

[0026] 2. When the bracket drives the driving member and the driving member is in operation, the sealing member can be driven synchronously, so that the internal components of the sealing member rise from the inside of the lower template, so that its internal structure contacts the bottom of the upper template. When the upper and lower templates are completely closed, the internal components of the sealing member can contact the upper template, thereby forming a seal, thereby improving the sealing between the lower and upper templates, reducing the possibility of the foaming material overflowing from the gap between the two when expanding inside the lower template, and improving the quality of the finished product.

[0027] 3. After the finished product is formed, the toggle piece is manually operated so that the internal component of the toggle piece drives the top contact piece, so that the internal component of the top contact piece pushes the trigger piece, so that the internal component of the trigger piece disconnects the clamping connection with the cutting piece. Under the elastic action of the internal component of the cutting piece, its internal structure is driven to cut the finished product, and the burrs generated on the edge of the finished product can be cut, and then the finished product is demoulded pre-processed to improve the quality of the finished product.

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1

[0045] See also Figures 1 to 10, is the first embodiment of the present invention, provides a technical solution: a foaming mold of an ultra-soft foam material, comprising a lower template 1, the top side of the lower template 1 is rotatably connected to the upper template 2, and both sides of the lower template 1 are provided with a receiving groove 11, a bracket 3 is installed inside the receiving groove 11, one side of the upper template 2 is connected to the bracket 3, and the top side of the lower template 1 is fixedly connected with a mutually symmetrical elastic buckle group 12. Here, the elastic buckle group 12 is made of elastic metal sheets, and one end is a metal clamping block. The elastic buckle group 12 is composed of two mutually symmetrical elastic metal sheets and metal clamping blocks, and is tilted on the lower template 1 so that the elastic buckle group 12 forms an inclined triangular shape, which is convenient for inserting into the slot 21. The bottom of the upper template 2 is provided with mutually symmetrical clamping grooves 21. The diameter of the clamping grooves 21 is larger than the installation setting range of the elastic buckle group 12, which will not affect the insertion of the elastic buckle group 12. An inner groove is opened on one side of the part, and an extrusion member 5 is installed inside the inner groove. A driving member 6 is fixedly connected to one side of the inner bottom of the receiving groove 11, and the driving member 6 is buckled with the extrusion member 5. A toggle member 4 is installed on one side of the lower template 1, and a top contact member 10 is installed on one side of the lower template 1. A trigger member 8 is installed on the bottom side of the upper template 2. Here, the top contact member 10 corresponds to the trigger member 8. When the lower template 1 and the upper template 2 are closed, the trigger member 8 and the top contact member 10 correspond vertically, and a cutting member 9 is installed inside the upper template 2, and mutually symmetrical reset members 7 are installed at one end of the upper template 2 near the rotating point. The reset member 7 is transmission-connected to the cutting member 9, and a sealing member 13 is installed inside the lower template 1. An installation chamber is provided inside the upper template 2, which can be used for the installation and operation of the reset member 7, the trigger member 8 and the cutting member 9. A plurality of exhaust ports are provided on the upper template 2, which can be used to exhaust the gas generated when the foaming material expands;

[0046] The upper template 2 is rotated to make it fit with the lower template 1. During the rotation of the upper template 2, the bracket 3 is driven, so that the bracket 3 drives the driving member 6 to release the connection with the extrusion member 5. At this time, the extrusion member 5 starts to operate and pushes the receiving groove 11 to the top, so that the receiving groove 11 is connected with the card slot 21, and the mold is closed.

[0047] The extrusion member 5 includes a transverse plate 51 slidably connected to the inside of the inner groove, and connecting rods 52 are fixedly connected to the top ends of the transverse plate 51. A symmetrical sliding groove is provided on one side of the lower template 1. Here, the sliding groove is arranged in the middle of the elastic buckle group 12, and a sleeve 53 is fixedly connected to the inside of the sliding groove. The connecting rod 52 passes through and is connected to the inside of the sleeve 53. A return spring 54 is sleeved on the outside of the sleeve 53. An extrusion block 55 is fixedly connected to the end of the connecting rod 52 away from the transverse plate 51. The outer surface of the extrusion block 55 and the inner side of the sliding groove are smoothed to improve the smoothness of the extrusion block 55 when moving. The extrusion block 55 resists the elastic buckle group 12, causing the elastic buckle group 12 to deform.

[0048] The bracket 3 includes a sliding rod 31 fixedly connected to the bottom of the storage groove 11, one end of the sliding rod 31 is rotatably connected to the auxiliary rod 32, and a damping slider 33 is connected through the sliding rod 31, and the top of the damping slider 33 is rotatably connected to the support rod 34, one end of the support rod 34 is rotatably connected to the upper template 2, and one side of the support rod 34 is rotatably connected to the auxiliary rod 32, and a push block 35 is fixedly connected to one side of the top of the damping slider 33.

[0049] The driving member 6 includes a connecting box fixedly connected to one end of the bottom of the storage groove 11, and a driving block 61 is slidably connected inside the connecting box. A protrusion 64 is provided on one side of the top of the driving block 61, and a clamping head 63 is provided on the other side of the top of the driving block 61. A tension spring 62 is fixedly connected to one side of the inside of the connecting box, and one end of the tension spring 62 is fixedly connected to the driving block 61. Here, a locking groove is provided on one side of the driving block 61, and is located below the clamping head 63, which is used to adapt to the movement and locking of the end of the cross-plate 51, and the protrusion 64 is in an inclined state, which can be used to resist the driving of the seal 13.

[0050] The toggle member 4 includes a handle 41 rotatably connected to one side of the lower template 1, a rotating rod 42 is fixedly connected to one side of the handle 41, and an arc-shaped toggle plate 43 is fixedly connected to the rotating rod 42. The arc-shaped toggle plate 43 is located inside the inner groove. Here, the arc-shaped toggle plate 43 is an arc-shaped structure that can be used to squeeze and toggle the top contact 10 and the cross-connecting plate 51.

[0051] When shaping the foam material, the demoulding liquid can be applied to the inside of the lower template 1 and the bottom of the upper template 2 first, and then the foam material can be poured into the lower template 1. After that, the upper template 2 can be manually pulled to flip the upper template 2 toward the lower template 1, thereby closing the upper template 2 and the lower template 1. When flipping, the support rod 34 can be driven during the movement of the upper template 2, so that one end of the support rod 34 pushes the damping slider 33, so that the damping slider 33 slides inside the slide rod 31, and then the damping slider 33 drives the push block 35 to move toward the direction of the driving member 6. When the upper template 2 and the lower template 1 are close to the closed state, the elastic buckle group 12 is embedded in the card slot 21. At this time, the push block 35 can contact one side of the driving block 61 and push the driving block 61 as the upper template 2 moves downward, thereby driving the driving block 61 to move, so that the clamping head 6 3. The buckled state of the cross-connecting plate 51 is released. Under the elastic action of the return spring 1 54, the extrusion block 55 can be pushed up, so that the extrusion block 55 moves upward, thereby squeezing the elastic buckle group 12, so that the elastic buckle group 12 gradually changes from the inclined state to the vertical state. When the lower template 1 and the upper template 2 are completely closed, the elastic buckle group 12 can completely form a vertical state, and then form a snap connection with the inner wall of the clamping groove 21, so that the lower template 1 and the upper template 2 are automatically locked when closed. The operation is simple, reducing the time spent on manually locking the mold, avoiding the possibility of expansion and overflow of the foaming material during the closing and locking process of the mold, improving the quality of injection molding, and thus improving the quality of the finished product. When the mold is closed, the foaming material can expand rapidly inside the lower template 1 and be shaped along the internal structure of the lower template 1, so that the finished product can be injection molded.

[0052] When demoulding is required, the handle 41 can be manually rotated so that the handle 41 drives the rotating rod 42 to rotate. The rotating rotating rod 42 drives the arc-shaped dial plate 43 to rotate, so that the arc-shaped dial plate 43 drives the cross-connecting plate 51, so that the cross-connecting plate 51 moves downward, thereby driving the connecting rod 52 to pull the extrusion block 55, so that the extrusion block 55 is re-entered into the sliding groove. At this time, the elastic buckle group 12 loses the extrusion force and rebounds, thereby re-entering the tilted state, thereby releasing the engagement with the clamping groove 21. Thereafter, the upper template 2 is manually pulled to turn the upper template 2. After rotating a certain distance, the handle 41 can be released. In the process of the upper template 2 turning upward, the damping slider 33 can be driven away from the driving block 61, and then the driving block 61 is pulled back to its original position under the elastic action of the tension spring 62, so that the clamping head 63 is re-engaged with the cross-connecting plate 51, thereby realizing the separation of the upper template 2 and the lower template 1, and then the molded finished product is demoulded.

[0053] Example 2

[0054] See also Figure 11, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the seal 13 includes a sealing plate 131 slidably connected to the inside of the lower template 1, and driving rods 132 are fixedly connected on both sides of the sealing plate 131. The bottom end of the driving rod 132 contacts the top of the driving block 61. Here, a rubber pad is provided on the top of the sealing plate 131, which can cooperate with the sealing plate 131 to enhance the sealing between the lower template 1 and the upper template 2, and the seal 13 is not a unique structure and can be changed according to the internal mold cavity structure of the lower template 1.

[0055] When the push block 35 moves the contact driving block 61, the protrusion 64 at the top end of the driving block 61 can contact the driving rod 132, so that the driving rod 132 moves upward along the structure of the protrusion 64, thereby driving the sealing plate 131 to move, so that the sealing plate 131 moves upward from the inside of the lower template 1, so that it contacts the bottom of the upper template 2. When the upper template 2 and the lower template 1 are completely closed, the sealing plate 131 contacts the upper template 2, thereby forming a seal, thereby improving the sealing between the lower template 1 and the upper template 2, reducing the possibility of the foaming material overflowing from the gap between the two when expanding inside the lower template 1, and improving the molding quality of the finished product.

[0056] When the driving block 61 rebounds and resets, the protrusion 64 is reset, and the driving rod 132 moves downward along the structure of the protrusion 64, thereby retracting the sealing plate 131 into the interior of the lower template 1 to complete the reset.

[0057] The remaining structures are the same as those of Example 1.

[0058] Example 3

[0059] See also Figures 12 to 14 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that: the top contact member 10 includes a sliding box fixedly connected to one side of the lower template 1, and a trigger block 101 is slidably connected inside the sliding box. The bottom of the trigger block 101 is fixedly connected to a guide rod 102, and the bottom end of the guide rod 102 is fixedly connected to a push plate 104. The outer side of the guide rod 102 is provided with a return spring 103. Here, the outer surface of the trigger block 101 and the inner side of the sliding box are smoothed to improve the smoothness of the movement of the trigger block 101.

[0060] The cutting piece 9 includes a knife plate 91 slidably connected to the inside of the upper template 2, and racks 93 are fixedly connected to both ends of one side of the knife plate 91, and a hook joint 94 is fixedly connected to the other side of the knife plate 91. A plurality of driving springs 92 are fixedly connected to both sides of the top of the knife plate 91. The trigger part 8 includes a hook 81 rotatably connected to the inside of the upper template 2, and a force plate 82 is fixedly connected to one side of the bottom end of the hook 81. A top block 83 is slidably connected to the inside of the upper template 2, and a reset spring 2 84 is fixedly connected to one side of the force plate 82. The reset spring 2 84 is connected to the upper template 2 at one end away from the hook 81.

[0061] When the pull wire 74 pulls the reset reel 71, it drives the reset reel 71 to rotate, and then drives the gear 73 to rotate through the overrunning clutch 72, and drives the cutting piece 9 to reset. When the reset reel 71 rotates automatically, it will not drive the gear 73 to rotate, and the gear 73 is in a free state when it is not driven.

[0062] When the finished product is demoulded, the handle 41 is manually rotated to drive the arc-shaped dial plate 43 to rotate, and the push plate 104 can be driven synchronously, so that the push plate 104 drives the guide rod 102 to move upward, and then drives the trigger block 101 to move toward the top block 83, and squeezes the top block 83, so that the top block 83 moves upward, and then squeezes the force-bearing plate 82, driving the hook 81 to rotate, so that the hook 81 releases the engagement with the hook joint 94, and then, under the elastic action of the driving spring 92, the knife plate 91 is pushed up, so that the knife plate 91 moves downward, and then the burrs on the edge of the finished product are cut, and then the finished product is pre-processed for demoulding, thereby improving the quality of the finished product.

[0063] When the upper template 2 is manually flipped and lifted, the pull wire 74 can pull the reset reel 71, causing the reset reel 71 to rotate, and then drive the gear 73 to rotate through the overrunning clutch 72. The rotating gear 73 can drive the rack 93, thereby pulling the knife plate 91 back to its original position and driving the hook joint 94 to re-engage with the hook 81, thereby completing the reset of the cutting piece 9. When the handle 41 is released, the push plate 104 loses the driving force of the arc-shaped dial plate 43. At this time, under the elastic action of the reset spring three 103, the push plate 104 is pushed up, thereby driving the trigger block 101 to reset.

[0064] The remaining structures are the same as those of Examples 1 and 2.

[0067] S1: Pour the foaming material into the lower template 1, then manually pull the upper template 2 and gradually fit it to the lower template 1, so that the elastic buckle group 12 is inserted into the slot 21. When the upper template 2 is pulled, the bracket 3 is driven to move, so that the bracket 3 drives the driving member 6, so that the driving member 6 releases the buckle connection with the extrusion member 5. Then, the extrusion member 5 squeezes the elastic buckle group 12, so that the elastic buckle group 12 is engaged with the slot 21, and the lower template 1 and the upper template 2 are closed.

[0068] S2: When the driving member 6 is driven, the sealing member 13 is driven so that the sealing member 13 moves toward the upper template 2 to form a seal at the gap between the lower template 1 and the upper template 2;

[0069] S3: After the lower template 1 and the upper template 2 are closed, the foam material expands inside the lower template 1 and expands and shapes along the internal structure of the lower template 1. After the foam material is completely shaped, the upper template 2 can be opened and demoulded;

[0070] S4: During demolding, the toggle member 4 is rotated so that the toggle member 4 drives the extrusion member 5 and simultaneously drives the top contact member 10, so that the top contact member 10 drives the trigger member 8 and releases the restriction on the cutting member 9, so that the cutting member 9 is triggered and the burrs of the finished product after shaping are removed;

[0071] S5: Afterwards, the upper template 2 is opened while the toggle member 4 remains in the screwed state, and then the toggle member 4 can be loosened. When opened, the reset member 7 can pull the cutting member 9 to reset. At this time, the driving member 6 is re-connected with the extrusion member 5, and then the shaped finished product can be taken out from the lower template 1.

[0072] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
