Description

Technical Field

[0001] The utility model relates to the technical field of demoulding devices, in particular to a rapid demoulding device for integrated polyurethane molding. Background Art

[0002] Polyurethane is a polymer material synthesized by the reaction of isocyanates and polyols. It is widely used in foam plastics, coatings, adhesives, and elastomers. Its properties, including excellent wear resistance, elasticity, and insulation, make it important in industries such as furniture, construction, and automobiles. Its integrated molding method offers benefits such as reduced assembly steps, improved production efficiency, lower manufacturing costs, and reduced material waste. By completing all steps in a single mold, higher product consistency and improved structural strength are achieved, while also streamlining the production process.

[0003] After polyurethane is demolded, it is typically transferred using a suction cup to facilitate subsequent processing. However, due to the stickiness of polyurethane during demolding, the molded polyurethane may adhere to either side of the mold, making it difficult to determine its position during subsequent transfer. In light of this, the present invention provides a rapid demolding device for integrated polyurethane molding. Utility Model Content

[0004] The purpose of the utility model is to address the problem in the background technology that due to the viscosity of polyurethane during demoulding, the molded polyurethane may adhere to the mold on either side, which makes it impossible to determine the position of the polyurethane when it is subsequently transferred.

[0033] Example

[0034] like Figure 1-4 As shown, the utility model proposes a rapid demoulding device for integrated polyurethane molding, including a fixed first mold 1 and a second mold 2 corresponding to the first mold 1. Liquid polyurethane is filled into the first mold 1 and the second mold 2, and after solidification, a polyurethane part is formed in one piece.

[0035] Furthermore, the demolding device includes a switching mechanism 3 disposed on the side of the second mold 2 facing away from the first mold 1. The switching mechanism 3 is used to drive the movement of the second mold 2. The switching mechanism 3 includes a vertical plate 31 disposed on the side of the second mold 2 facing away from the first mold 1. A fixed plate 32 is also disposed on the side of the vertical plate 31 facing the second mold 2. Both the vertical plate 31 and the fixed plate 32 are fixedly mounted. A rotating rod 33 is rotatably connected between the vertical plate 31 and the fixed plate 32, and the rotating rod 33 rotates in position. A limiting post 34 is fixedly connected to the rotating rod 33, and the limiting post 34 rotates in position together with the rotating rod 33. The limiting post 34 is in the shape of a regular square prism. A limiting sleeve 35 is slidably mounted on the limiting post 34, so that rotation of the limiting post 34 drives the limiting sleeve 35 to rotate synchronously, but movement of the limiting sleeve 35 does not drive movement of the limiting post 34. A mounting plate 36 is mounted on the limiting sleeve 35, and the mounting plate 36 rotates synchronously with the limiting sleeve 35. The second mold 2 and the suction cup group 4 are both fixedly connected to the side of the mounting plate 36 close to the first mold 1. When the mounting plate 36 rotates, it drives the second mold 2 and the suction cup group 4 to switch positions.

[0036] Furthermore, the demoulding device further includes a suction cup group 4 installed on the switching mechanism 3, and the suction cup group 4 is used for adsorbing the molded polyurethane.

[0037] Specifically, the demolding device includes a drive assembly 5 mounted on the switching mechanism 3. The drive assembly 5 is used to drive the second mold 2 to swap positions with the suction cup assembly 4. The drive assembly 5 includes a first push rod motor 51 mounted on the side of the vertical plate 31 near the second mold 2. The output end of the first push rod motor 51 is fixedly connected to a rack 52. When the first push rod motor 51 is activated, it drives the rack 52 to move. A gear 53 is provided on one side of the rack 52, meshing with it. When the rack 52 moves, it drives the gear 53 to rotate. The gear 53 is fixedly mounted on the limit post 34. When the gear 53 rotates, it drives the limit post 34 to rotate synchronously. Sliders 54 are mounted on both sides of the rack 52. The outer sides of the two sets of slides 54 are slidably connected to limit blocks 55. The limit blocks 55 are fixedly connected to the side of the vertical plate 31 and are fixed in position, allowing the rack 52 to move smoothly under the restraining action of the slides 54 and the limit blocks 55.

[0038] Furthermore, the demolding device includes a limiting mechanism 6 disposed within the switching mechanism 3. The limiting mechanism 6 is used to ensure smooth movement of the second mold 2 and the suction cup assembly 4. The limiting mechanism 6 includes two sets of slide bars 61 fixedly connected to the side of the mounting plate 36 away from the second mold 2. The slide bars 61 move synchronously with the mounting plate 36. Slide sleeves 62 are slidably connected to both sets of slide bars 61. As the slide bars 61 rotate with the mounting plate 36, they drive the slide sleeves 62 to rotate synchronously. Simultaneously, as the mounting plate 36 moves, the slide bars 61 slide within the slide sleeves 62. Guide blocks 63 are mounted on opposite sides of the two sets of slide sleeves 62. A guide ring 64 is slidably connected to both sets of guide blocks 63. The guide ring 64 is annular and centered around the rotating rod 33. The limiting action of the guide blocks 63 and the guide ring 64 ensures smooth rotation of the slide sleeves 62 and the slide bars 61. A plurality of positioning plates 65 are fixedly connected to one side of the vertical plate 31 close to the guide ring 64 . Connecting columns 66 are fixedly connected between the positioning plates 65 and the guide ring 64 . The positioning plates 65 and the connecting columns 66 fix the position of the guide ring 64 .

[0039] Finally, the demolding device further includes a movable assembly 7 for achieving demolding. The movable assembly 7 includes a second push rod motor 71 mounted on the side of the vertical plate 31 near the first mold 1. The output end of the second push rod motor 71 faces the first mold 1. The second push rod motor 71 is used to drive the mounting plate 36 toward the first mold 1 after activation, thereby facilitating the second mold 2 to be closely attached to the first mold 1 for casting. Simultaneously, during demolding, the formed polyurethane adheres to the first mold 1, and the second push rod motor 71 facilitates driving the suction cup assembly 4 toward the polyurethane. The movable assembly 7 also includes multiple groups of third push rod motors 72 mounted on the side of the fixed plate 32 away from the mounting plate 36. The output end of the third push rod motor 72 extends through the fixed plate 32 toward the mounting plate 36. The third push rod motor 72 is used to drive the second mold 2 away from the first mold 1 after activation, thereby exposing the formed polyurethane. The third push rod motor 72 is also used to remove the polyurethane from the first mold 1 after the suction cup assembly 4 absorbs the formed polyurethane.

[0040] In this embodiment, the second push rod motor 71 is first activated to extend. After the second push rod motor 71 contacts the mounting plate 36, it pushes the second mold 2 so that the second mold 2 is close to the first mold 1. Then, liquid polyurethane is filled into the first mold 1 and the second mold 2 and allowed to solidify. At the same time, the second push rod motor 71 and the third push rod motor 72 are activated. The second push rod motor 71 shortens while the third push rod motor 72 extends. At this time, the output end of the third push rod motor 72 contacts the mounting plate 36, pushing the mounting plate 36 and the limit sleeve 35 to slide on the limit post 34. At this time, the second mold 2 moves away from the first mold 1.

[0041] When the formed polyurethane adheres to the first mold 1, the first push rod motor 51 is started to drive the rack 52 to move. The rack 52 moves and meshes with the gear 53, causing the gear 53 to drive the limiting column 34 to rotate. The limiting column 34 then drives the mounting plate 36 to rotate through the limiting sleeve 35. The mounting plate 36 is started to rotate smoothly under the limiting action of the guide block 63 and the guide ring 64, causing the suction cup group 4 to move downward. The second push rod motor 71 then extends and the third push rod motor 72 shortens, driving the suction cup group 4 to contact and absorb the polyurethane. The second push rod motor 71 then shortens and the third push rod motor 72 extends, causing the suction cup group 4 to remove the polyurethane from the first mold 1. The first push rod motor 51 is then started to reset, and the suction cup group 4 moves upward to facilitate the external suction cup to absorb the polyurethane.

[0042] When the formed polyurethane adheres to the second mold 2, the first push rod motor 51 is activated to move the rack 52. The rack 52 moves and meshes with the gear 53, causing the gear 53 to rotate the limiting post 34. The limiting post 34 then rotates the mounting plate 36 via the limiting sleeve 35. The mounting plate 36 is then activated and smoothly rotated under the restraining action of the guide block 63 and the guide ring 64, allowing the second mold 2 to move upward. This allows the polyurethane to be directly sucked up by the external suction cup.

[0043] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
