Description

Technical Field

[0001] The present invention relates to the technical field of foaming molds, and specifically to a foaming mold and a foaming method for ultra-soft foaming materials. 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 characteristics such as light weight, heat insulation, sound insulation, and buffering, and are widely used in fields such as construction, packaging, automobiles, and household appliances.

[0003] When using foaming materials to produce finished products, the foaming materials will first be processed, such as heated and melted and injected with a foaming agent, and then the processed foaming materials will be poured into a mold through an external injection machine, so that the raw materials foam and expand in the mold cavity to form a foamed finished product.

[0004] When the existing molds shape the foaming materials, it is necessary to first inject the processed foaming materials into the mold through an injection machine, and then close the mold so that the materials expand and shape in the mold. However, when processing the foaming materials, different materials are added with different materials, so that the expansion speed of the foaming materials is also different. When closing the mold, it is necessary to first close the mold structure and then fix and close it through multiple latches or connectors, and the operation process takes a certain amount of time. When shaping foaming materials with a relatively fast expansion speed, it is easy that the mold structure is not fully closed due to the latches or connectors not being fully locked, resulting in the materials overflowing during the operation process, which is not conducive to shaping production.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 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 inside of the card slot. 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 card connection with the inner wall of the card 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 expansion and overflow of the foaming material in the process of closing and locking the mold, improving the injection molding quality, and thereby improving the quality of the finished product; 2. When the bracket drives the driving member and the driving member is running, 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 conflicts with the bottom of the upper template. When the upper template and the lower template are completely closed, the internal components of the sealing member can conflict with the upper template, thereby forming a seal, thereby improving the sealing between the lower template and the upper template, reducing the possibility of the foaming material overflowing from the gap between the two when the foaming material expands inside the lower template, and improving the molding quality of the finished product; 3. After the finished product is formed, the toggle piece is manually operated so that the internal components of the toggle piece drive the top contact piece, so that the internal components of the top contact piece push the trigger piece, so that the internal components of the trigger piece disconnect the clamping connection with the cutting piece, and under the elastic action of the internal components of the cutting piece, the internal structure of the cutting piece is driven to cut the finished product, and the burrs on the edge of the finished product can be cut, and then the finished product can be demolded pre-processed to improve the quality of the finished product.

A driving member 6 is fixedly connected to one side of the inner bottom of the storage 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 one side of the bottom 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 a mutually symmetrical reset member 7 is installed at one end of the upper template 2 close to the rotation point. The reset member 7 is transmission-connected with 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; 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 buckle of 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 snap-fitted with the card slot 21, and the mold can be closed.

[0034] 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 two ends of the transverse plate 51. A symmetrical sliding groove is opened on one side of the lower template 1. Here, the sliding groove is set 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 outer side 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, so that the elastic buckle group 12 is deformed.

[0035] 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, the top of the damping slider 33 is rotatably connected to a 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.

[0036] 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 clamping 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 clamping of the end of the cross-connecting plate 51, and the protrusion 64 is in an inclined state, which can be used to resist the driving of the sealing member 13.

[0037] 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, an arc-shaped toggle plate 43 is fixedly connected to the rotating rod 42, and 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 for squeezing and toggling the top contact 10 and the cross-connecting plate 51.

[0038] When shaping the foaming material, the inner part of the lower template 1 and the bottom of the upper template 2 can be coated with a release agent first, and then the foaming material is poured into the lower template 1. After that, manually pull the upper template 2 to make the upper template 2 flip towards the lower template 1, so that the upper template 2 and the lower template 1 form a closure. During the 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, making the damping slider 33 slide inside the slide rod 31. Then, the damping slider 33 drives the push block 35 to move towards the driving part 6. When the upper template 2 and the lower template 1 are close to the closed state, the elastic buckle group 12 is embedded into the card slot 21. At this time, the push block 35 can be in contact with 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 chuck 63 releases the buckling state of the cross-connecting plate 51. Under the elastic action of the first return spring 54, the extrusion block 55 can be pushed upward, so that the extrusion block 55 moves upward, and then the elastic buckle group 12 is extruded, so that the elastic buckle group 12 gradually changes from an inclined state to a vertical state. When the lower template 1 and the upper template 2 are completely closed, the elastic buckle group 12 can be completely in a vertical state, and then form a snap connection with the inner wall of the card slot 21, so as to realize the automatic locking of the lower template 1 and the upper template 2 when they are closed. The operation is simple, which reduces the time spent by people manually locking the mold, avoids the possibility of the foaming material expanding and overflowing during the process of closing and locking the mold, improves the injection quality, and then improves the finished product quality. After the mold is closed, the foaming material can quickly expand inside the lower template 1 and be shaped along the internal structure of the lower template 1, and then the finished product injection production can be realized.

[0039] When demolding is required, the handle 41 can be manually rotated to drive the rotating rod 42 to rotate. The rotating rod 42 drives the arc-shaped dial 43 to rotate, so that the arc-shaped dial 43 drives the cross-connecting plate 51, making the cross-connecting plate 51 move downward. Then, the connecting rod 52 drives the extrusion block 55 to be pulled, so that the extrusion block 55 is retracted into the sliding groove again. At this time, the elastic buckle group 12 loses the extrusion force and rebounds, and then returns to the inclined state again, so as to release the snap connection with the card slot 21. After that, manually pull the upper template 2 to make the upper template 2 flip. After rotating a certain distance, the handle 41 can be released. During the upward flipping process of the upper template 2, 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 chuck 63 re-clamps the cross-connecting plate 51, so as to realize the separation of the upper template 2 and the lower template 1, and then demold the shaped finished product.

[0040] Embodiment 2 Please refer to Figure 11, which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the seal 13 includes a sealing plate 131 slidably connected inside the lower template 1. Driving rods 132 are fixedly connected to both sides of the sealing plate 131. The bottom end of the driving rod 132 is in contact with 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 performance between the lower template 1 and the upper template 2. Moreover, the seal 13 is not the only structure and can be changed according to the structure of the mold cavity inside the lower template 1.

[0041] When the pushing block 35 moves the abutting driving block 61, the protruding portion 64 at one end of the top of the driving block 61 can abut against the driving rod 132, causing the driving rod 132 to move upward along the structure of the protruding portion 64, thereby driving the sealing plate 131 to move, making the sealing plate 131 move upward from inside the lower template 1 and abut against the bottom of the upper template 2. When the upper template 2 and the lower template 1 are completely closed, the sealing plate 131 abuts against the upper template 2, thus forming a seal, so as to improve the sealing performance between the lower template 1 and the upper template 2 and reduce the possibility of the foaming material overflowing from the gap between the two when expanding inside the lower template 1, and improve the quality of the finished product shaping.

[0042] When the driving block 61 rebounds and resets, the protruding portion 64 is reset, and the driving rod 132 moves downward along the structure of the protruding portion 64, thereby retracting the sealing plate 131 back into the lower template 1 to complete the reset.

[0043] The remaining structures are the same as those in Embodiment 1.

[0044] Embodiment 3 Please refer to Figures 12 to 14 , which is the third embodiment of the present invention.

Here, the outer surface of the trigger block 101 and the inner side of the sliding box are both smooth, which can improve the smoothness of the movement of the trigger block 101.

[0045] The cutting member 9 includes a knife plate 91 slidably connected inside the upper template 2. Rack bars 93 are fixedly connected to both ends of one side of the knife plate 91. Moreover, 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 member 8 includes a hook 81 rotatably connected inside the upper template 2. A force-bearing plate 82 is fixedly connected to one side of the bottom end of the hook 81. A top block 83 is slidably connected inside the upper template 2. A second return spring 84 is fixedly connected to one side of the force-bearing plate 82. The end of the second return spring 84 away from the hook 81 is connected to the upper template 2.

[0046] The reset member 7 includes a reset reel 71 rotatably connected to one side inside the upper template 2. One side of the reset reel 71 is fixedly connected to an overrunning clutch 72. One side of the overrunning clutch 72 is fixedly connected to a gear 73. The gear 73 is meshed with a rack 93. A pull wire 74 is wound around the reset reel 71. One end of the pull wire 74 away from the reset reel 71 is fixedly connected to the top of the lower template 1. Here, a torsion spring is provided inside the reset reel 71 for the automatic rotation of the reset reel 71. One side of the reset reel 71 is connected to the driving shaft of the overrunning clutch 72, and the driving shaft direction of the overrunning clutch 72 is fixedly connected to the gear 73. 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 member 9 to reset. When the reset reel 71 rotates automatically, it will not drive the gear 73 to rotate, and when the gear 73 is not driven, it is in a free state.

[0047] After demolding the finished product, when manually rotating the turning handle 41 to drive the arc-shaped dial 43 to rotate, 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 towards the top block 83 and squeeze the top block 83, so that the top block 83 moves upward, and then squeezes the stress plate 82 to drive the hook 81 to rotate, so that the hook 81 releases the clamping of the hook joint 94. After that, under the elastic action of the driving spring 92, the knife plate 91 is pushed upwards, so that the knife plate 91 moves downward, and then cuts the burrs on the edge of the finished product, and then performs demolding pretreatment on the finished product to improve the quality of the finished product.

[0048] When manually flipping and lifting the upper template 2, the pull wire 74 can pull the reset reel 71, so that the reset reel 71 rotates, and then drives the gear 73 to rotate through the overrunning clutch 72. The rotating gear 73 can drive the rack 93, and then pull the knife plate 91 back to its original position and drive the hook joint 94 to form a clamping connection with the hook 81 again, so as to complete the reset of the cutting member 9. When the turning handle 41 is released, the push plate 104 loses the driving force of the arc-shaped dial 43. At this time, under the elastic action of the third reset spring 103, the push plate 104 is pushed upwards, and then drives the trigger block 101 to reset.

[0049] The remaining structures are the same as those of Embodiments 1 and 2.
