Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiberglass production technology, and in particular to a fiberglass curing and molding equipment with automatic temperature control function. Background Technology
[0002] Fiberglass, or fiber reinforced composite plastic, generally refers to reinforced plastics made by reinforcing unsaturated polyester, epoxy resin, and phenolic resin matrices with glass fibers or their products as reinforcing materials. It is called glass fiber reinforced plastic or fiberglass. Unlike tempered glass, when fiberglass is used to cure and mold some large products, the wound mandrel needs to be sent into the molding equipment for heating and curing.
[0003] For example, CN215040471U discloses a fiberglass heating and curing molding device, which includes a device base. Support legs are fixedly installed at the four corners of the bottom outer surface of the device base. Bottom columns are fixedly installed on the bottom outer surface of the support legs. The bottom outer surface area of the bottom columns is larger than the bottom outer surface area of the support legs. A curing and molding chamber is fixedly installed inside the device base. A first hinge is rotatably installed at the left end of the front outer surface of the curing and molding chamber. A first front cover is fixedly installed on the right outer surface of the first hinge.
[0004] In the existing technology, the wound core mold is directly cured at high temperature. Rapid curing will lead to the concentration of thermal stress and a significant temperature difference between the surface and the interior of the product. The surface resin cures prematurely while the interior remains liquid, resulting in uneven curing. At the same time, uneven temperature can also easily cause deformation of the product surface, affecting the curing and molding quality of the product. Utility Model Content
[0005] The purpose of this invention is to solve the problem in the existing technology that directly curing the wound core mold at high temperature and rapid curing will lead to thermal stress concentration, uneven curing and surface deformation, which will affect the curing and molding quality of the product. Therefore, this invention proposes a fiberglass curing and molding equipment with automatic temperature control function.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fiberglass curing and molding equipment with automatic temperature control function, comprising a conveying assembly, a curing and molding box fixedly connected to the top side of the conveying assembly, and isolation mechanisms installed on both sides of the curing and molding box. A preheating mechanism is installed on one side of one set of isolation mechanisms, the preheating mechanism comprising a preheating box fixedly connected to the top side of the conveying assembly, a fan fixedly connected to the top side of the preheating box, inner plates fixedly connected to both sides of the interior of the preheating box, a cavity provided between one side of the two inner plates and the interior of the preheating box, a transition box fixedly connected to one side of the other set of isolation mechanisms, the transition box fixedly connected to the top of the conveying assembly, and a curing heating mechanism installed inside the curing and molding box. The curing heating mechanism comprises a guide plate and a fixing frame, the fixing frame fixedly connected to the interior of the conveying assembly, a first heating pipe installed inside the fixing frame, a second heating pipe fixedly connected between the two guide plates, and the second heating pipe positioned above the first heating pipe.
[0007] Preferably, a connecting frame is fixedly connected to one side of the guide plate, and the top of the connecting frame is fixedly connected to the inside of the curing box.
[0008] Preferably, the top of the connecting frame is fixedly connected to an air guide pipe, the other end of the air guide pipe is fixedly connected to a fan, and one side of the fan is fixedly connected to one side of the conveying component via a mounting bracket.
[0009] Preferably, doors are installed on one side of the preheating box and one side of the transition box, and an isolation frame is fixedly connected inside the preheating box. The bottom two sides of the isolation frame are fixedly connected to the top of the two inner plates respectively.
[0010] Preferably, air outlets are provided on the sides of both inner plates, and a third heating tube is fixedly connected inside the isolation frame.
[0011] Preferably, the isolation mechanism includes a fixed plate, one side of which is fixedly connected to one side of the curing and molding box, and an electric push rod is fixedly connected to the top of the fixed plate. One end of the electric push rod passes through the fixed plate and is fixedly connected to the isolation plate.
[0012] Preferably, guide rails are slidably connected to both sides of the isolation plate, and one side of the two guide rails is fixedly connected to one side of the fixed plate.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, the third heating tube first heats the air inside the isolation frame, and the fan drives the air to circulate. The hot air is blown out from the air outlet, forming a low-temperature pre-curing zone inside the preheating box to preheat the core mold. The second heating tube works with the first heating tube to heat the upper and lower areas of the core mold together, providing heat for the curing of fiberglass. After heating and curing, the core mold enters the transition box for post-processing. By using zoned heating to preheat the pre-curing zone and control the temperature in the high-temperature zone for rapid curing, the temperature zone is dynamically adjusted, solving the problems of uneven curing, high energy consumption, large deformation, and poor material compatibility in traditional curing technologies.
[0015] 2. In this utility model, isolation mechanisms are installed on both sides of the curing and molding box. The electric push rod drives the isolation plate to move, so that the isolation plate can close the connection between the curing and molding box and the preheating box, and the connection between the curing and molding box and the transition box respectively. The isolation mechanism acts as a physical barrier to divide the preheating box, the curing and molding box and the transition box into independent temperature zones, so as to avoid the direct mixing of hot air from the high temperature zone and the low temperature zone, which would lead to a chaotic temperature gradient.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1: As Figures 1-5 As shown, this utility model provides a fiberglass curing and molding equipment with automatic temperature control function, including a conveying assembly 1. A curing and molding box 2 is fixedly connected to the top side of the conveying assembly 1. Isolation mechanisms 4 are installed on both sides of the curing and molding box 2. A preheating mechanism 6 is installed on one side of one set of isolation mechanisms 4. The preheating mechanism 6 includes a preheating box 61, which is fixedly connected to the top side of the conveying assembly 1. A fan 66 is fixedly connected to the top side of the preheating box 61. Inner layer plates 62 are fixedly connected to both sides of the interior of the preheating box 61. A cavity is provided between one side of the two inner layer plates 62 and the inner side of the preheating box 61. A transition box 3 is installed on one side of the other set of isolation mechanisms 4. The transition box 3 is fixedly connected to the conveying assembly 1. At the top, a curing heating mechanism 5 is installed inside the curing molding box 2. The curing heating mechanism 5 includes a guide plate 55 and a fixing frame 53. The fixing frame 53 is fixedly connected to the inside of the conveying assembly 1. A first heating pipe 54 is installed inside the fixing frame 53. A second heating pipe 57 is fixedly connected between the two guide plates 55. The second heating pipe 57 is located above the first heating pipe 54. A connecting frame 56 is fixedly connected to one side of the guide plate 55. The top of the connecting frame 56 is fixedly connected to the inside of the curing molding box 2. A duct 52 is fixedly connected to the top of the connecting frame 56. A fan 51 is fixedly connected to the other end of the duct 52. One side of the fan 51 is fixedly connected to one side of the conveying assembly 1 through a mounting bracket.
[0025] A preheating mechanism 6 is provided at the front end of the curing and molding box 2. When the core mold enters the preheating box 61, the third heating pipe 64 operates to heat the air inside the isolation frame 65. The fan 66 operates to drive the airflow, blowing the hot air from inside the isolation frame 65 into the cavity separated from the two inner layer plates 62 by the preheating box 61. Then, the hot air is blown out from the air outlets 63 opened on the two preheating mechanisms 6, preheating the core mold from both sides. A low-temperature pre-curing zone is formed inside the preheating box 61, allowing the solvent in the resin to slowly evaporate. Afterward, the core mold enters the curing and molding box 2. The second heating tube 57 works in conjunction with the first heating tube 54 to heat the upper and lower areas of the core mold together, providing heat for the curing of fiberglass. The fan 51 drives the gas through the air duct 52 into the interior of the connecting frame 56 at regular intervals, which can accelerate the flow of hot air inside the curing and molding box 2. After heating and curing, the core mold enters the transition box 3 for post-processing. By using zoned heating for preheating in the pre-curing zone and temperature control in the high-temperature zone for rapid curing, the temperature zone can be dynamically adjusted, solving the problems of uneven curing, high energy consumption, large deformation, and poor material compatibility in traditional curing technology.
[0026] Example 2: Figure 1 , Figure 2 and Figure 5 As shown, a door 7 is installed on one side of the preheating box 61 and one side of the transition box 3. An isolation frame 65 is fixedly connected inside the preheating box 61. The bottom two sides of the isolation frame 65 are fixedly connected to the top of the two inner layer plates 62 respectively. An air outlet 63 is opened on the side of the two inner layer plates 62. A third heating pipe 64 is fixedly connected inside the isolation frame 65. The isolation mechanism 4 includes a fixing plate 41. One side of the fixing plate 41 is fixedly connected to one side of the curing box 2. An electric push rod 42 is fixedly connected to the top of the fixing plate 41. One end of the electric push rod 42 passes through the fixing plate 41 and is fixedly connected to the isolation plate 43. Guide rails 44 are slidably connected to both sides of the isolation plate 43. One side of the two guide rails 44 is fixedly connected to one side of the fixing plate 41.
[0027] The overall effect of this embodiment is that doors 7 are installed on one side of the preheating box 61 and one side of the transition box 3. The connection of the doors 7 is connected by a torsion spring. After the core mold moves and opens and then separates from the two doors 7, the deformed torsion spring can drive the doors 7 to close automatically. Isolation mechanisms 4 are installed on both sides of the curing and molding box 2. When heating for curing and molding, the electric push rod 42 drives the isolation plate 43 to move. The isolation plate 43 slides on the inside of the guide rail 44 and fixes the isolation plate 43 to make linear movement. This allows the isolation plate 43 to close the connection between the curing and molding box 2 and the preheating box 61, and the connection between the curing and molding box 2 and the transition box 3, respectively. The isolation mechanism 4 acts as a physical barrier to divide the preheating box 61, the curing and molding box 2, and the transition box 3 into independent temperature zones, avoiding direct mixing of hot air from the high-temperature zone and the low-temperature zone, which would cause a chaotic temperature gradient. When the core mold position is moved, the electric push rod 42 drives the isolation plate 43 to rise, facilitating the passage of the core mold.
[0028] The operating method and working principle of this device are as follows: A preheating mechanism 6 is set at the front end of the curing and molding box 2. When the core mold enters the preheating box 61, the third heating pipe 64 heats the air inside the isolation frame 65. The fan 66 drives the airflow, blowing the hot air from inside the isolation frame 65 into the cavity separated from the preheating box 61 by the two inner plates 62. Then, the hot air is blown out from the air outlets 63 on the two preheating mechanisms 6, preheating the core mold from both sides. The electric push rod 42 drives the isolation plate 43 to rise, and the core mold is transported into the curing and molding box 2. The second heating pipe 57 and the first heating pipe 64 heat the air inside the cavity separated from the preheating box 61. When the heat pipe 54 is working, it can heat the upper and lower areas of the core mold together. When the fan 51 is working, it drives the gas through the air duct 52 into the interior of the connecting frame 56, which can accelerate the flow of hot air inside the curing and molding box 2 and control the temperature. When the curing and molding process is heating, the electric push rod 42 is working to move the isolation plate 43, which closes the connection between the curing and molding box 2 and the preheating box 61, and the connection between the curing and molding box 2 and the transition box 3 respectively. The isolation mechanism 4 acts as a physical barrier to divide the preheating box 61, the curing and molding box 2 and the transition box 3 into independent temperature zones. Then, the heated and cured core mold enters the interior of the transition box 3 for post-processing.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
