Description

Technical Field

[0001] The utility model belongs to the technical field of fiberglass tank production, and particularly relates to a production mold for a fiberglass tank body. Background Art

[0002] A fiberglass tank, also known as a fiberglass storage tank, is a storage container made of fiberglass material. In the production process of the fiberglass tank body, injection molding and resin slurry coating are key process steps. After these steps, the tank body needs to be heated in the mold so that the resin can be fully cured, thereby enabling the tank body to obtain the desired strength, stability, and durability.

[0003] However, when the tank body is cured and shaped in the mold, its temperature is usually still very high, which poses challenges to subsequent production steps and the safe operation of workers. Since the temperature of the fiberglass tank body after heating and curing can reach several hundred degrees Celsius, such a high temperature not only affects production efficiency but may also damage the mold and shorten its service life. The traditional natural cooling method is not only inefficient but may also cause uneven cooling inside and outside the tank body, thereby affecting the quality and performance of the tank body.

The phrase appears at various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present utility model provides a production mold for a fiberglass tank, as Figures 1-4As shown in the figure, the production mold for a fiberglass tank body includes: a mold base 1, on which a cooling shell 2 is installed through columns. Inside the cooling shell 2, there is a mold shell 3 for producing the fiberglass tank body. Inside the mold shell 3, there is a separable mold core 5, and at the top end of the mold core 5, a mold cover 4 is fixedly installed; a liquid storage tank 6 for storing coolant, which is fixedly installed on the top of the mold base 1; a liquid pumping pump 7 for pumping the coolant, which is arranged on the mold base 1; a liquid suction pipe 8, which is fixedly installed at the liquid inlet end of the liquid pumping pump 7, and the liquid inlet end of the liquid suction pipe 8 extends into the liquid storage tank 6; a liquid injection pipe 9, which is fixedly connected to the lower part of one side of the cooling shell 2, and the liquid inlet end of the liquid injection pipe 9 is fixedly connected to the liquid outlet end of the liquid pumping pump 7; a return pipe 10, which is fixedly connected to the upper part of one side of the cooling shell 2, and the liquid outlet end of the return pipe 10 extends into the liquid storage tank 6; a control mechanism for controlling the opening, closing and turning of the mold cover 4, which is arranged on the mold base 1.

[0022] It should be noted that during the production process of the fiberglass tank body, especially in the resin curing stage, the tank body needs to undergo a heating process in the mold. This process is usually to ensure that the resin can fully react and cure, thereby endowing the tank body with sufficient strength and stability. However, when the tank body is cured, its temperature is often very high, reaching several hundred degrees Celsius. The high-temperature tank body needs to wait for natural cooling to a lower temperature before subsequent processing or handling, which significantly increases the production cycle. The long waiting time means a reduction in production efficiency, as well as a waste of equipment and human resources. The long-term high-temperature environment will cause damage to the materials and structures of the mold. The mold materials may soften, deform or crack due to high temperature, resulting in a shortened service life and the need for frequent replacement. This not only increases production costs but also may affect the stability of the production process. The traditional natural cooling method relies on air convection and radiation heat dissipation, and its efficiency is very low. This means that the tank body needs a long time to cool down to the safe operating temperature range. In addition, due to the differences in the shape and materials of the tank body, natural cooling often leads to uneven cooling inside and outside the tank body. This uneven cooling may cause stress inside the tank body, thereby affecting its quality and performance. Therefore, in order to solve the above problems, a new type of production mold for fiberglass tank bodies needs to be developed;

[0023] In this embodiment, the mold base 1 serves as the foundation of the entire mold, providing stable support for other components; the cooling shell 2 is arranged on the mold base 1 and internally houses the mold shell 3 to form a closed cooling environment; the mold shell 3 is used to produce the main part of the fiberglass tank, and its shape determines the external contour of the tank; the mold core 5 is detachably installed inside the mold shell 3 to form the internal shape of the tank; the mold cover 4 is fixed to the top end of the mold core 5 to close the mold during the resin curing stage and prevent resin leakage; the liquid storage tank 6 is fixedly installed on the top of the mold base 1 to hold the coolant; the liquid extraction pump 7 is arranged on the mold base 1 to extract the coolant from the liquid storage tank 6; the liquid extraction pipe 8 connects the liquid inlet end of the liquid extraction pump 7 and the liquid storage tank 6 to ensure that the coolant can be effectively extracted; the liquid injection pipe 9 connects the liquid outlet end of the liquid extraction pump 7 and the cooling shell 2 to inject the coolant into the cooling shell 2 to cool the mold shell 3; the return pipe 10 leads out from the cooling shell 2 to return the cooled coolant to the liquid storage tank 6 to realize the recycling of the coolant; arranged on the mold base 1, it is used to control the opening, closing and rotation of the mold cover 4 to ensure the convenience and safety of operation; through the cooling system composed of the liquid extraction pump 7, the liquid extraction pipe 8, the liquid injection pipe 9 and the return pipe 10, the coolant can be quickly injected into the cooling shell 2 to efficiently cool the mold shell 3, which greatly shortens the time required for the tank to cool to the safe operating temperature and improves the production efficiency. Since the coolant directly acts on the mold shell 3 inside the cooling shell 2, uniform cooling of the inside and outside of the tank can be achieved; this avoids the generation of internal stress in the tank caused by uneven cooling and ensures the quality and performance of the tank; through timely and effective cooling, the mold is prevented from being in a high-temperature state for a long time, thereby reducing problems such as softening, deformation and cracking of the mold material and prolonging the service life of the mold.

[0024] In a further preferred embodiment of the present utility model, the control mechanism includes: a mounting frame 11 fixedly installed on the mold base 1; a rotating shaft 12 rotatably installed on the mounting frame 11; an assembly seat 13 fixedly installed on the top end of the rotating shaft 12; a motor 14 fixedly installed on the mounting frame 11 for driving the rotating shaft 12 to rotate, and the output shaft of the motor 14 is fixedly connected to the bottom end of the rotating shaft 12; a cylinder 15 fixedly installed on the assembly seat 13; a connecting plate 16 fixedly installed on the top end of the output rod of the cylinder 15, and the bottom of the connecting plate 16 is fixedly connected to the top of the mold cover 4.

[0025] In this embodiment, the mounting bracket 11 is fixedly installed on the mold base 1, serving as the support foundation for the entire control mechanism to ensure the stable installation of other components; the rotating shaft 12 is rotatably installed on the mounting bracket 11, providing a rotation axis for the opening and closing of the mold cover 4; the assembly seat 13 is fixedly installed at the top end of the rotating shaft 12, serving as the installation platform for the cylinder 15 to ensure the stability and vertical movement of the cylinder 15; the motor 14 is fixedly installed on the mounting bracket 11, and its output shaft is fixedly connected to the bottom end of the rotating shaft 12. The rotation of the motor 14 can drive the rotation of the rotating shaft 12, thereby controlling the opening and closing angle of the mold cover 4; the cylinder 15 is fixedly installed on the assembly seat 13, and the lifting movement of the mold cover 4 is realized through the telescopic movement of its output rod; the connecting plate 16 is fixedly installed at the top end of the output rod of the cylinder 15, and its bottom is fixedly connected to the top of the mold cover 4. The connecting plate 16 ensures that the output force of the cylinder 15 can directly act on the mold cover 4 to realize its lifting action; through the combined use of the motor 14 and the cylinder 15, the automatic opening, closing, lifting and lowering of the mold cover 4 are realized. This not only improves the operation convenience, but also reduces the errors and potential safety hazards that may be brought by manual operation; the motor 14 can accurately control the rotation angle of the rotating shaft 12 to ensure that the opening and closing angle of the mold cover 4 meets the production requirements. At the same time, the cylinder 15 can also accurately control the lifting height of the mold cover 4 to ensure its close fit with the mold shell 3; the automatic control makes the opening, closing, lifting and lowering of the mold cover 4 fast and accurate, reducing the waiting time in the production process and improving the production efficiency.

[0026] In a further preferred embodiment of the present utility model, an air inlet pipe 17 for guiding cold air is arranged in the liquid storage tank 6, and the air inlet end of the air inlet pipe 17 extends outside the liquid storage tank 6.

[0027] In this embodiment, the air inlet pipe 17 arranged in the liquid storage tank 6 mainly functions to introduce external cold air into the liquid storage tank 6. The air inlet end of the air inlet pipe 17 extends outside the liquid storage tank 6, allowing external cold air (such as cold air or cold air processed by a cooling system) to enter the liquid storage tank 6; by introducing external cold air, the air inlet pipe 17 can reduce the temperature in the liquid storage tank 6 and further cool the coolant in the liquid storage tank 6. When the coolant is injected into the cooling shell 2 through the liquid injection pipe 9 to cool the mold shell 3, the low-temperature coolant can more effectively reduce the temperature of the mold shell 3, thereby improving the efficiency of the entire cooling system; as the coolant is continuously used in the circulation system, its temperature will gradually increase. By introducing external cold air through the air inlet pipe 17, it can help maintain the temperature of the coolant within a lower and stable range. This helps to ensure the continuity and stability of the cooling effect, thereby improving the production efficiency and product quality.

[0028] In a further preferred embodiment of the present utility model, a liquid replenishing port is opened at the top of the liquid storage tank 6, a cover plate 18 is arranged in the liquid replenishing port, and an air outlet pipe 19 is arranged on the cover plate 18.

[0029] In this embodiment, a liquid replenishing port is provided at the top of the liquid storage tank 6, which facilitates adding new coolant to the liquid storage tank 6 in a timely manner when the coolant is insufficient. The setting of the liquid replenishing port makes the process of replenishing coolant simple and fast, improving the convenience of production operations; a cover plate 18 is provided in the liquid replenishing port. The function of the cover plate 18 is to close the liquid replenishing port when the coolant does not need to be added, preventing the coolant from overflowing or dust and impurities from entering the liquid storage tank 6. The setting of the cover plate 18 not only ensures the cleanliness of the liquid storage tank 6 but also ensures the purity of the coolant, thus guaranteeing the cooling effect; an air outlet pipe 19 is provided on the cover plate 18. The main function of the air outlet pipe 19 is to discharge the gas in the liquid storage tank 6. Especially when adding new coolant, the air outlet pipe 19 can discharge the gas generated due to the addition of coolant, preventing the gas from accumulating in the liquid storage tank 6. At the same time, during the coolant circulation process, the air outlet pipe 19 can also help to discharge the gas generated due to temperature changes, maintaining the pressure balance in the liquid storage tank 6.

[0030] In a further preferred embodiment of the present utility model, an air inlet hole and an exhaust hole are provided at the top of the mold cover 4, and a liquid replacement pipe is fixedly communicated with one side of the cooling shell 2, and a valve is provided on the liquid replacement pipe.

[0031] In this embodiment, an air inlet hole is provided at the top of the mold cover 4 to allow external air or a specific gas to enter the mold interior, which helps to provide the required air or gas environment during specific stages in the production process of the fiberglass tank body, such as the resin curing stage; similarly, an exhaust hole is provided at the top of the mold cover 4 to allow the gas inside the mold to be discharged; during the resin curing process, gas or steam may be generated, and the presence of the exhaust hole can timely discharge these gases, preventing them from having an adverse effect on the quality of the tank body; the liquid replacement pipe is fixedly communicated with one side of the cooling shell 2 for replacing or replenishing the coolant when needed. A valve is provided on the liquid replacement pipe to control the flow of the coolant, ensuring that the system can maintain an appropriate pressure and flow rate when replacing or replenishing the coolant.

[0032] In a further preferred embodiment of the present utility model, support columns are symmetrically and fixedly installed at the bottom of the assembly seat 13, balls are embedded at the bottom ends of the support columns, and an annular groove adapted to the balls is provided at the top of the mounting frame 11.

[0033] In this embodiment, support columns are symmetrically and fixedly installed at the bottom of the assembly seat 13. These support columns provide additional support for the assembly seat 13, ensuring its stability and balance during rotation; balls are embedded at the bottom ends of the support columns. The design of the balls can significantly reduce the friction force of the assembly seat 13 during rotation, making the rotation smoother; an annular groove adapted to the balls is provided at the top of the mounting frame 11. The annular groove provides a sliding track for the balls, ensuring that the balls always move on a predetermined path when the assembly seat 13 rotates.

[0034] In summary, the cooling system composed of the liquid extraction pump 7, the liquid extraction pipe 8, the liquid injection pipe 9 and the return pipe 10 can quickly inject the coolant into the cooling shell 2 to efficiently cool the mold shell 3. This greatly shortens the time required for the tank body to cool to the safe operating temperature, improves the production efficiency, and solves the problem of low cooling efficiency of the fiberglass tank body after curing and shaping in the prior art.
