Description

Technical Field

[0001] This utility model relates to the field of mold cooling technology, specifically a rapid cooling device for epoxy resin pressure gel molding. Background Technology

[0002] Epoxy resin pressure gel molding is a crucial process in epoxy resin processing, widely used in the production of insulating components for electrical equipment. Traditional epoxy resin pressure molding equipment typically requires removing the resin from the mold for cooling after pouring it into the mold. This process is time-consuming, leading to a prolonged overall production cycle and low manufacturing efficiency. To shorten production time and increase output per unit time, a device capable of rapid cooling within the mold is needed, thereby reducing the time required for the cooling process and improving production efficiency.

[0003] Existing devices mainly involve adding cooling channels inside the mold for rapid cooling. These devices are largely similar to cooling devices for plastic mold processing that provide rapid cooling. The structure of device CN216658821U includes a mold body, with symmetrically arranged support frames at the bottom of the mold body. A cooling box is fixedly connected to the bottom of the support frames, and support seats are symmetrically arranged at the bottom of the cooling box. An oil inlet pipe is fixedly connected to the bottom of the mold body, and a connecting pipe is fixedly connected to one end of the oil inlet pipe. Heat dissipation plates are equidistantly connected to the connecting pipe. This invention uses cooling oil for heat exchange, which to some extent solves the problem of low cooling efficiency in existing molds. However, there are still areas for optimization in this device.

[0004] Existing devices primarily absorb heat from the mold through a cooling medium, requiring two sets of liquid supply components to cool a pair of molds, resulting in complex coolant delivery pipelines. Furthermore, some coolant expands upon absorbing heat, making it difficult for some devices to buffer the expansion deformation, leading to structural deformation and damage to parts of the cooling tank, thus reducing the device's efficiency and practicality. Therefore, to address these issues, a rapid cooling device for epoxy resin pressure gel molding molds is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 One embodiment provided by this utility model:

[0025] A rapid cooling device for a mold used in epoxy resin pressure gel molding includes a right cooling box 11, a right mold 12 fixedly connected inside the right cooling box 11, an injection seat 13 fixedly connected to the top center of the right mold 12, a left mold 14 on the left side of the right mold 12, a left cooling box 15 fixedly connected to the left side of the left mold 14, and a buffer cylinder 16 fixedly connected to the top of the left cooling box 15.

[0026] The right cooling tank 11 has a partitioned flow channel 21 inside. A water inlet seat 22 is fixedly connected to the top right side of the right cooling tank 11, and a drain seat 23 is fixedly connected to the top left side of the right cooling tank 11. This design allows coolant to be injected into the right cooling tank 11 through the water inlet seat 22 and discharged through the drain seat 23. A socket 24 is fixedly installed on the upper left side of the right cooling tank 11. The left cooling tank 15 has a through flow channel 25 inside, and a plug 26 is fixedly installed on the upper right side of the left cooling tank 15. This design allows coolant to flow sequentially through the partitioned flow channel 21 and the through flow channel 25 to cool the right mold 12 and the left mold 14.

[0027] A first through hole 31 is provided on the left side of the plug 26, and a pin 32 is fixedly connected to the left side of the inner wall of the plug 26. A second through hole 33 is provided on the left side of the outer wall of the socket 24, and a valve core 34 is slidably mounted on the left side of the interior of the socket 24. A limiting rod 35 is inserted into the right side of the valve core 34, and the right end of the limiting rod 35 is fixedly connected to the right side of the inner wall of the socket 24. Through this design, the pin 32 can be inserted into the interior of the socket 24 and push the valve core 34 to slide to the right. A compression spring 36 is fixedly connected to the right side of the inner wall of the socket 24, located on the outer ring of the limiting rod 35, and the left end of the compression spring 36 is fixedly connected to the left side of the interior of the valve core 34. Through this design, the valve core 34 can compress the compression spring 36 and open the second through hole 33.

[0028] A movable rod 41 is inserted into the rear wall of the buffer cylinder 16. A piston 42 is fixedly connected to the front end of the movable rod 41, and the outer wall of the piston 42 slides against the inner wall of the buffer cylinder 16. This design allows the piston 42 to drive the movable rod 41 to slide in a limited position. A buffer spring 43 is fixedly connected to the rear side of the piston 42, located on the outer ring of the movable rod 41. The rear end of the buffer spring 43 is fixedly connected to the rear side of the inner wall of the buffer cylinder 16. This design allows the buffer spring 43 to drive the piston 42 to automatically reset.

[0029] Working principle: When it is necessary to connect the cooling boxes, the plug 26 is first slid by the left cooling box 15. The plug 26 drives the pin 32 to be inserted into the socket 24 and pushes the valve core 34 to slide backward. The valve core 34 compresses the spring 36 and opens the second through hole 33, so that the coolant can flow between the left cooling box 15 and the right cooling box 11, realizing the connection operation of the cooling boxes.

[0030] When the coolant needs to expand and buffer, the coolant first expands due to heat and enters the interior of the buffer cylinder 16. The expanded coolant pushes the piston 42 to slide backward. The piston 42 drives the movable rod 41 to slide synchronously and compress the buffer spring 43, thus realizing the expansion and buffering operation of the coolant. The operation ends here.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
