Description

Technical Field

[0001] This utility model relates to the field of silicone processing equipment, and in particular to a silicone demolding device. Background Technology

[0002] In the production of silicone products, vulcanization is one of the key processes that determines the product's performance. After high-temperature vulcanization, the silicone material completes cross-linking and curing, forming a finished product with a certain strength and elasticity. However, due to the strong flexibility and adhesion of silicone, after vulcanization, the finished product usually adheres tightly to the lower mold cavity of the mold, making it difficult to detach naturally and posing significant challenges to the demolding process.

[0003] Currently, most silicone product manufacturers still rely primarily on manual methods for demolding. Operators need to use simple tools, such as pneumatic air blowers, to manually remove the finished silicone product from the mold cavity. This method is not only labor-intensive and inefficient, but also requires a high level of skill from the operators. In actual operation, due to the high surface temperature of the mold, workers are prone to burns if they are not careful, posing a significant safety risk. Therefore, a silicone demolding device is proposed to solve the above problems. Utility Model Content

[0004] The main purpose of this invention is to provide a silicone demolding device that solves the problems of high labor intensity and low production efficiency of existing demolding devices.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a silicone demolding device, including a mold conveying table of a vulcanizing machine, and further including:

[0006] The combined lower mold includes a fixed mold fixed on the top of the mold conveyor table. The top of the fixed mold is provided with a groove, in which a movable mold is movably embedded and a silicone molding cavity is formed between the two. The two side walls of the groove are symmetrically provided with slots. The two sides of the movable mold are symmetrically provided with plates that are adapted to the slots, and the plates extend to the outside of the slots.

[0007] The demolding mechanism includes a lifting and rotating mechanism. The lifting and rotating end of the lifting and rotating mechanism is equipped with a demolding component via a connecting frame. The demolding component includes a housing that can cover the top of the fixed mold. The housing has receiving openings on both side walls that correspond to the clamping plate. Above the receiving openings is a lifting component that lifts the movable mold through the clamping plate. The outer side of the housing is also equipped with a blower mechanism facing the clamping slot. The housing is also equipped with a gripping component for gripping silicone.

[0008] In the preferred embodiment, the lifting component includes a bending seat, a through-hole is provided on the horizontal plate of the bending seat, a rotary cylinder is installed above the through-hole, a telescopic cylinder is installed on the rotating table of the rotary cylinder through the through-hole, and a lifting plate is provided on the telescopic end of the telescopic cylinder.

[0009] In the preferred embodiment, the blower mechanism includes a support frame 1 disposed on both sides of the receiving port, and an air diffuser hood disposed at the end of the support frame 1. The air outlet of the air diffuser hood is tilted upward and faces the slot, and its air inlet is connected to a high-pressure blower through an air pipe.

[0010] In the preferred embodiment, the gripping component includes a second support frame mounted on top of the housing. A lifting cylinder is installed on the top of the second support frame. The telescopic end of the lifting cylinder passes through the second support frame and is connected to a lifting plate. Multiple pneumatic suction cups are installed on the lifting plate. The base of the pneumatic suction cups moves through the second support frame and is connected to a vacuum system.

[0011] In a preferred embodiment, the lifting and rotating mechanism includes a lifting hydraulic cylinder, a rotating bearing is provided on the telescopic end of the lifting hydraulic cylinder, a rotating shaft is mounted on the rotating bearing, and a drive mechanism for driving the rotating shaft to rotate is also provided on the telescopic end of the lifting hydraulic cylinder.

[0012] In a preferred embodiment, the drive mechanism includes a drive device mounted on the telescopic end of the lifting hydraulic cylinder, a transmission gear is provided on the output end of the drive device, and a driven gear meshing with the transmission gear is provided on the outside of the rotating shaft.

[0013] In the preferred embodiment, the connecting frame one includes a T-shaped cantilever set at the top of the rotating shaft, and connecting frames two extending downward are provided on both sides of the wide end of the T-shaped cantilever, and the connecting frames two are connected to the housing.

[0014] This invention provides a silicone demolding device. The shell of the demolding component can be placed above the combined lower mold to form a relatively enclosed operating space. This not only effectively prevents impurities from entering the mold cavity during demolding, ensuring the cleanliness of the production environment, but also provides a good airflow guiding area for subsequent air-blowing separation. When the movable mold is lifted by the lifting component, a certain gap is formed between the silicone product and the fixed mold. At this time, the blowing mechanism can accurately blow high-pressure air into this gap area. The airflow diffuses along the contact surface between the silicone and the movable mold, quickly reducing the adhesion between the two, thereby achieving rapid and stable separation of the silicone product from the movable mold. This avoids quality problems such as product deformation and tearing caused by mechanical prying or manual peeling in traditional demolding methods. At the same time, the gripping component and the lifting component work together. After the silicone product is separated from the movable mold, the pneumatic suction cup can accurately adsorb the product surface and complete the gripping action. Then, the lifting and rotating mechanism realizes the lifting and transfer of the product. The entire demolding process is continuous, efficient, safe and reliable. This structure not only significantly improves demolding efficiency and product yield, but also effectively replaces traditional manual operation, reducing labor intensity and operational risks.

[0026] Example 1

[0027] like Figure 1-9 As shown, a silicone demolding device includes a mold conveying platform 1 for a vulcanizing machine, a combined lower mold 2, and a demolding mechanism 3. The mold conveying platform 1 is mainly used for loading and unloading materials outside the vulcanizing machine, as well as carrying raw materials to the vulcanizing machine for vulcanization. This is prior art in the field and therefore will not be described in detail here.

[0028] Furthermore, the combined lower mold 2 includes a fixed mold 201 fixedly mounted on the top of the mold conveyor table 1. The top of the fixed mold 201 is provided with a groove 205, in which a movable mold 202 is movably embedded, forming a silicone molding cavity between the two. In this embodiment, a protrusion is provided in the groove 205, and a mold hole is provided on the movable mold 202. The required mold cavity is formed by the combination of the protrusion and the mold hole. During processing, the silicone raw material is placed on the movable mold 202, and then the mold conveyor table 1 is moved to the vulcanizing machine for molding. This process is prior art in the field and therefore will not be described in detail here.

[0029] The groove 205 has symmetrical slots 203 on its two side walls. The movable mold 202 has symmetrically arranged plates 204 on both sides that are adapted to the slots 203, and the plates 204 extend to the outside of the slots 203, providing effective conditions for separation between the two.

[0030] Furthermore, the demolding mechanism 3 includes a lifting and rotating mechanism 31. The lifting and rotating end of the lifting and rotating mechanism 31 is equipped with a demolding component 33 via a connecting frame 32. The demolding component 33 includes a housing 330 that can cover the top of the fixed mold 201. The housing 330 has receiving openings 331 on both side walls that correspond to the clamping plate 204. Above the receiving openings 331, there is a lifting component 332 that lifts the movable mold 202 through the clamping plate 204. The outer side of the housing 330 is also provided with a blower mechanism 333 facing the clamping slot 203. The housing 330 is also provided with a gripping component for gripping silicone.

[0031] With this design, the demolding component 33 can be rotated to the mold conveying table 1 of the vulcanizing machine using the lifting and rotating mechanism 31. Using its lifting function, the housing 330 of the demolding component 33 can be placed over the combined lower mold 2. Then, the movable mold 202 can be lifted above the fixed mold 201 by the lifting component 332, completing the initial separation of the silicone product. During this process, since the contact area between the silicone product and the fixed mold 201 is small, the product quality will not be affected during the separation process. At the same time, a gap can be formed between the two, and the gap is surrounded by the housing 330 except for the slot 203. Then, the gripping component can grab the silicone product on the movable mold 202. Then, the blowing mechanism 333 blows high-pressure airflow into the gap between the movable mold 202 and the fixed mold 201, so that the silicone product is separated from the movable mold 202. Thus, the silicone product is separated under the gripping of the gripping component, and the lifting and rotating mechanism 31 can transfer the silicone product.

[0032] In the preferred embodiment, the lifting component 332 includes a bending seat 3320, which consists of a vertical plate and a horizontal plate set at the top of the vertical plate. A through-hole 3321 is provided on the horizontal plate of the bending seat 3320. A rotary cylinder 3322 is installed above the through-hole 3321. A telescopic cylinder 3323 is installed on the rotating platform of the rotary cylinder 3322 through the through-hole 3321. A lifting plate 3324 is provided on the telescopic end of the telescopic cylinder 3323.

[0033] This design allows the lifting plate 3324 to be height-adjusted by the extension and retraction of the telescopic cylinder 3323, and by lifting upwards, it can drive the movable mold 202 to detach from the fixed mold 201. During this process, the direction of the lifting plate 3324 can be adjusted by the rotation function of the rotary cylinder 3322, thereby achieving the effect of moving it below the card plate 204 in conjunction with the lifting and lowering.

[0034] The control system of the aforementioned cylinder uses a common commercially available product, so it will not be described in detail here.

[0035] In the preferred embodiment, the blower mechanism 333 includes a support frame 3330 disposed on both sides of the receiving port 331, and an air diffuser 3331 disposed at the end of the support frame 3330. The air outlet of the air diffuser 3331 is inclined upward and faces the slot 203. Its air inlet is connected to a high-pressure blower through an air pipe.

[0036] This design allows high-pressure airflow to be blown upwards into the gap between the movable mold 202 and the fixed mold 201. Under the encirclement of the housing 330, the airflow lifts the silicone product on the movable mold 202 from below, thereby separating the two. Combined with the upper body of the gripping component, this achieves the demolding effect.

[0037] In the preferred embodiment, the gripping component includes a second support frame 334 mounted above the housing 330. The second support frame 334 includes four support legs and a top plate mounted on the support legs. A lifting cylinder 337 is mounted on the top of the second support frame 334. In this embodiment, there are two lifting cylinders 337. The telescopic ends of the lifting cylinders 337 pass through the second support frame 334 and are connected to a lifting plate 335, thereby controlling the lifting plate 335 to rise and fall. A plurality of pneumatic suction cups 336 are mounted on the lifting plate 335. The seats of the pneumatic suction cups 336 move through the second support frame 334 and are connected to a vacuum system.

[0038] It should be noted that the pneumatic suction cup 336 should be positioned away from the mold cavity so that the movable mold 202 can provide planar support during gripping, ensuring the sealing of the gripping.

[0039] This design allows for the adsorption and extraction of finished silicone products by utilizing the pneumatic suction cup 336 in conjunction with the lifting plate 335.

[0040] In the preferred embodiment, the lifting and rotating mechanism 31 includes a lifting hydraulic cylinder 310. A rotating bearing 311 is provided on the telescopic end of the lifting hydraulic cylinder 310, and a rotating shaft 312 is mounted on the rotating bearing 311. The telescopic end of the lifting hydraulic cylinder 310 is also provided with a drive mechanism for driving the rotating shaft 312 to rotate. Thus, by lifting the lifting hydraulic cylinder 310, the overall height of the demolding component 33 can be controlled, and by rotating the rotating shaft 312, its transfer effect can be achieved.

[0041] Furthermore, the drive mechanism includes a drive device 314 mounted on the telescopic end of the lifting hydraulic cylinder 310. The drive device 314 is composed of a drive motor and a reducer. A transmission gear 315 is provided on the output end of the drive device 314, and a driven gear 313 that meshes with the transmission gear 315 is provided on the outside of the rotating shaft 312.

[0042] With this design, the rotation of the rotating shaft 312 can be achieved by using the drive device 314 and the transmission between the transmission gear 315 and the driven gear 313.

[0043] In the preferred embodiment, the connecting frame 32 includes a T-shaped cantilever 320 disposed on the top of the rotating shaft 312, and connecting frames 321 extending downward on both sides of the wide end of the T-shaped cantilever 320, the connecting frames 321 being connected to the housing 330.

[0044] It should be noted that, in order to improve structural strength, appropriate reinforcing ribs can be installed at the corners.

[0045] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
