Description

Technical Field

[0001] The invention relates to the technical field of cooling type resin manufacturing moulds, in particular to a high-efficiency cooling type phenolic resin piston manufacturing mould. Background Art

[0002] In today's industrial production field, with the rapid development of various industries, the performance and adaptability requirements of pistons are becoming more and more stringent, which makes the shapes of pistons rich and diverse to meet the operating requirements of different equipment such as automobile engines and hydraulic machinery under different working conditions.

[0003] In the traditional phenolic resin piston manufacturing process, each uniquely shaped piston must be equipped with a specially designed and manufactured mold; this mold customized production method brings many inconveniences and disadvantages; at the same time, the mold cooling link is particularly important in the phenolic resin piston manufacturing process.

[0004] This phenomenon is particularly prominent when facing pistons with complex shapes; since pistons of different shapes have different wall thickness distributions, structural characteristics, and heat conduction characteristics, there are significant differences in the demand for cooling intensity during the cooling process. For example, for some pistons, the bottom part often requires a stronger cooling effect to ensure the rapid solidification and structural stability of the material due to the greater pressure and friction heat; while the upper part requires a relatively lower cooling intensity. However, the existing fixed spiral cooling and serpentine cooling methods are very powerless in dealing with such complex and changeable cooling needs; the layout of the fixed cooling channel inside the mold is fixed, and its cooling rate is relatively uniform throughout the mold cavity. It is difficult to flexibly adjust according to the special needs of different parts of the piston, and it is impossible to effectively achieve precise control of the bottom and upper parts of the piston, which have obvious differences in cooling needs; this uneven cooling will cause serious stress concentration inside the piston. During the cooling process, due to the inconsistent shrinkage rates of different parts, internal stress gradually accumulates. When the stress value exceeds the ultimate strength of the phenolic resin material, cracks will appear on the surface or inside of the piston, seriously damaging the quality and reliability of the piston. In addition, uneven cooling will also cause deviations in the dimensional accuracy of the piston. Because of the difference in shrinkage amounts in different parts, the final molding size of the piston deviates from the design size, affecting the assembly accuracy of the piston and the cylinder body, and thus having an adverse effect on the performance and operating stability of the entire equipment.

[0005] In addition, in the process of using the mold for manufacturing phenolic resin pistons, the cooling channel in the cooling link exerts cooling efficiency and directly affects the curing process of the phenolic resin inside the mold. However, in the cooling water cooling mode widely used in the field of mold cooling, during the actual cooling operation, the cooling water usually contains impurities such as rust and scale, which are difficult to avoid; with the continuous advancement of time, these impurities will gradually deposit on the inner wall of the cooling channel; when a specific cooling channel is blocked, the cooling efficiency of the corresponding mold area will be sharply reduced, resulting in a significant imbalance in the mold temperature distribution; the phenolic resin piston manufactured under the above circumstances is very likely to cause shape deformation due to the differences in the curing speed and shrinkage degree experienced by the resin in different parts, which has a very serious negative impact on the dimensional accuracy and appearance quality of the product; at the same time, uneven cooling will cause uneven stress distribution inside the product, and cracking is very likely to occur in areas with highly concentrated local stress, which will greatly weaken the mechanical strength and reliability of the piston. In severe cases, the product may even be directly scrapped, resulting in a large amount of resource waste and a significant increase in cost.

[0006] Therefore, the present invention proposes a high-efficiency cooling type phenolic resin piston manufacturing mold to solve the above problems. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a high-efficiency cooling type phenolic resin piston manufacturing mold to solve the problems existing in the prior art.

[0016] As an improvement, the filling pipe A is fixedly connected to an automatic drain valve.

[0017] As an improvement, the plug-in slot and the thermal isolation sleeve are matched.

[0018] Compared with the prior art, the present invention provides a high-efficiency cooling type phenolic resin piston manufacturing mold, which has the following beneficial effects: 1. The present invention adds a design of a spiral attached tube that can circulate cooling water on the basis of a fixed cooling channel, and can flexibly adjust the thread distance between the spiral attached tubes according to demand. This design brings many significant advantages to the overall cooling work and the manufacturing of phenolic resin pistons: First: Accurate local temperature control: By adjusting the thread distance between the spiral attached tubes, the cooling intensity of different areas of the mold can be accurately adjusted. For example, in the case where the bottom of the piston requires strong cooling and the upper part requires weak cooling, the density of the bottom spiral attached tube can be accurately increased, that is, the thread distance of the spiral attached tube is reduced to strengthen the cooling, and the spacing of the upper spiral attached tube is increased to reduce the cooling intensity; this effectively solves the problem that the existing fixed cooling method is difficult to meet the differentiated cooling needs of complex-shaped pistons, and ensures that the resin curing speed and shrinkage degree of each part of the piston during the molding process are more uniform, thereby greatly reducing the internal stress concentration phenomenon caused by uneven cooling, significantly reducing the risk of cracks on the surface or inside of the piston, and greatly improving the quality and reliability of the piston, so that it can better adapt to various harsh working environments.

[0019] Second: Improve dimensional accuracy: Since precise local cooling control can be achieved, the problem of excessive differences in shrinkage in different parts caused by uneven cooling can be effectively avoided, so that the final molding size of the piston can more accurately meet the design requirements, effectively improving the assembly accuracy of the piston and cylinder matching parts, ensuring the performance stability and smooth operation of the entire equipment, reducing equipment failures and maintenance costs caused by poor assembly, and improving the overall service life and work efficiency of the equipment.

[0020] Third: Extend the service life of the mold: Precise cooling control and good cooling efficiency help reduce the thermal stress damage to the mold caused by excessive temperature or excessive temperature fluctuations, reduce the thermal fatigue of the mold material, effectively extend the service life of the mold, and reduce the frequency of mold replacement and maintenance costs.

[0021] 2. The present invention can effectively improve the cooling efficiency and stability through the overall design of multiple types of cooling adapter components; the contact area and heat exchange path between the cooling medium and the mold are increased in the spiral attached tube through which cooling water can circulate, thereby significantly improving the cooling efficiency without changing the basic structure of the original cooling system; even in a long-term continuous production process, the temperature of the mold can be stably maintained within a reasonable range, avoiding the problems of incomplete curing of phenolic resin and difficulty in demolding due to insufficient cooling, reducing the defective rate of products, improving the production qualification rate of products, and reducing the waste of resources and cost increase caused by product quality problems.

[0022] In addition, the adaptability and flexibility of the cooling system are enhanced; the adjustable thread distance of the spiral attachment tube enables the cooling system to quickly adapt to phenolic resin piston manufacturing molds of different shapes and different cooling requirements. Whether it is the production of high-performance pistons with special structures or conventional standard pistons, the cooling component can optimize the cooling strategy through simple thread distance adjustment, without the need to redesign and manufacture the cooling water flow channel for each new piston shape like traditional fixed cooling molds, which greatly shortens the mold development cycle, reduces mold manufacturing costs, and improves the company's production efficiency and market adaptability.

[0023] 3. The present invention can effectively improve the impurity filtering performance by adopting a rotating design for the sintered metal fiber felt filter element and adding a magnetic rod; that is, the rotating design of the sintered metal fiber felt filter element breaks the limitations of traditional static filtration. During the rotation process, the adsorption distribution of impurities on the surface of the filter element is more uniform, effectively avoiding the premature clogging of the filter element caused by excessive accumulation of impurities in local areas; at the same time, the centrifugal force generated by the rotation can cause larger particles of impurities to leave the surface of the filter element, further reducing the risk of filter element clogging, extending the service life of the filter element, and reducing the maintenance cost and downtime of frequent replacement of the filter element.

[0024] In addition, the insertion of the magnetic rod plays an adsorption role on magnetic impurities in the cooling water, such as iron filings; these magnetic impurities are often difficult to be effectively removed by conventional filtering methods, but the magnetic rod can accurately capture them, preventing them from entering the cooling channel and the spiral attached tube and causing adverse consequences such as wear, blockage and affecting heat conduction; through the synergistic effect with the rotating filter element, it achieves multi-directional and efficient interception of impurities in the cooling water, greatly improving the cleanliness of the cooling water, ensuring the stable operation of the cooling system, and providing reliable cooling guarantee for piston manufacturing.

[0025] At the same time, the cooling effect and piston quality are optimized; that is, due to the significant improvement in the filtering effect, impurities in the cooling water cannot interfere with the normal heat exchange function of the channel. This allows all parts of the mold to be cooled evenly and efficiently according to the predetermined cooling strategy, effectively avoiding local cooling anomalies caused by impurities; thereby ensuring that the curing process of phenolic resin in the mold is uniform and stable, greatly reducing the internal stress concentration of the piston caused by uneven cooling. The probability of quality problems such as surface cracks, deformation, and dimensional deviations in the piston is significantly reduced, and the mechanical strength, wear resistance, and dimensional accuracy of the piston are improved, ensuring that the piston can operate stably and reliably under various complex working conditions, and improving the overall quality and performance of the piston product.

[0026] 4. The present invention, through the overall design of the channel interference factor processing component, filters the cooling water when it enters the cooling area, which brings many significant and key beneficial effects to the overall cooling work and the manufacture of phenolic resin pistons: First, prevent the cooling water from being blocked through the channel and ensure cooling uniformity: the component can effectively avoid the blockage problem caused by the deposition of impurities in the cooling channel and the inner wall of the spiral attachment tube; that is, because the cooling water flow route is always kept unobstructed, the cooling capacity of each area of ​​the mold can be stably maintained, and the uneven cooling phenomenon caused by partial channel blockage is completely eliminated; this enables the phenolic resin piston to solidify and shrink evenly in various parts during the manufacturing process, greatly reducing the internal stress caused by uneven cooling, effectively preventing cracks on the surface or inside of the piston, and significantly improving the quality and reliability of the piston, ensuring its stable operation under various working conditions.

[0027] Second: Improve cooling efficiency and ensure production efficiency: Unfiltered cooling water impurities will adhere to the wall of the cooling water channel, forming a thermal resistance layer and reducing the heat exchange efficiency. This component uses a sintered metal fiber felt filter element to isolate and remove impurities, ensuring the smoothness and thermal conductivity of the cooling water flowing through the cooling channel and the spiral attached tube, so that the cooling system can efficiently take away the heat from the mold; this not only speeds up the curing speed of phenolic resin, shortens the molding cycle of the piston, and increases the output per unit time, but also reduces the need to extend the cooling time or perform additional operations for secondary cooling due to insufficient cooling, thereby effectively improving the overall production efficiency and ensuring that more high-quality piston products can be produced in the same time; at the same time, since the cooling water flow channel is effectively prevented from being blocked, the mold does not need to be frequently cleaned, repaired or replaced due to blockage; this significantly reduces the maintenance cost of the mold, including labor costs, maintenance material costs, and production line downtime losses caused by mold maintenance.

[0028] 5. The present invention can reduce the risk and cost of mold scrapping in the field of phenolic resin piston manufacturing molds through the coordinated design of the spiral attached tube and the channel interference factor processing component: when the cooling water flows through the channel of the traditional mold and is blocked, since its channel is often constructed by directly slotting on the mold, once the blockage occurs and is difficult to clean and repair, the entire mold has to be scrapped, which undoubtedly brings huge economic losses to the company, including the manufacturing cost of the mold, the loss of production stagnation due to the scrapping of the mold, and the purchase cost of new molds; and the replaceable feature of the spiral attached tube in the present invention makes it possible to replace the spiral attached tube component in a targeted manner when a problem occurs with the related part, without scrapping the entire mold; this greatly reduces the risk of mold scrapping, effectively reduces the high cost caused by mold scrapping, and significantly improves the economy of mold use and resource utilization.

[0029] In addition, the mold maintenance efficiency and production continuity can be improved: in the existing integrated cooling mold design, the maintenance work after the cooling water flow through the channel is blocked is complicated and time-consuming, and often requires a long period of downtime for processing, which seriously affects the continuity and efficiency of production; and the spiral attachment tube and channel interference factor processing component matching structure of the present invention make the mold maintenance work more convenient and efficient; when the spiral attachment tube parts need to be replaced or maintained, its replaceable design can quickly realize the disassembly and installation of the parts, greatly shortening the mold maintenance time. At the same time, since there is no need to carry out large-scale maintenance or replacement of the entire mold, the production line can resume normal production more quickly, reducing the production interruption time caused by mold maintenance, and improving production continuity and overall production efficiency.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0045] Example: Please refer to Figures 1 to 3 , Figures 5 to 7 As shown: In order to solve the problems mentioned in the technical solution, an embodiment of the present application provides a high-efficiency cooling phenolic resin piston manufacturing mold, including: a molding seat 1, an ejector tube 2, the ejector tube 2 is fixedly connected to the molding seat 1, and a groove is provided on the molding seat 1, and also includes: a multi-type cooling adapter component 3, a channel interference factor processing component 4, and the channel interference factor processing component 4 is located in the multi-type cooling adapter component 3.

[0046] The multi-type cooling adapter component 3 is used to adapt to the stability cooling of piston molding manufacturing with different shapes, thereby reducing the shortage of finished pistons and the cracking of the finished pistons.

[0047] The multi-type cooling adapter component 3 includes an upper plate 301, an upper mold 302 is fixedly connected to the bottom surface of the upper plate 301, telescopic rods 303 are fixedly connected to the four corners of the bottom surface of the upper plate 301, a column cavity 304 is embedded in the groove on the forming seat 1, a stamping forming cavity 305 is provided in the inner cavity of the column cavity 304, a liquid filling tube A306 is fixedly connected through the bottom surface of the outer ring wall of the column cavity 304, a cooling channel 307 is provided on the column cavity 304, a ring-shaped partition plate 308 is slidably connected in the cooling channel 307, a transfer arc tube 309 is fixedly connected to the bottom of the inner cavity of the cooling channel 307, one end of the transfer arc tube 309 is fixedly connected to a spiral attachment tube 310, the spiral attachment tubes 310 are spirally distributed in the cooling channel 307, and liquid filling tubes B311 are fixedly connected to the column cavity 304 at equal intervals, and the liquid filling tube B311 is connected to the cooling channel 307.

[0048] Among them: the multi-type cooling adapter component 3 is used to adapt to the stability cooling of piston molding manufacturing with different shapes, reducing the shortage of finished pistons and cracking.

[0049] In the manufacture of spark plugs of different shapes, there is no need to replace the column cavity 304, only the upper mold 302 needs to be replaced, so the disassembly rate is small and the adaptability is strong.

[0050] The telescopic rod 303 can drive the upper plate 301 to move, thereby changing the relative position of the upper mold 302 and the column cavity 304 .

[0051] The filling pipe A306 is mainly used to fill cooling water into the transfer arc tube 309.

[0052] One end of the spiral attached tube 310 is connected to the transfer arc tube 309, and the other end is connected to the output tube; that is, the liquid filling tube A306, the transfer arc tube 309, the spiral attached tube 310, the output tube at one end of the spiral attached tube 310, and the external delivery pump and cooling box can form a cooling circulation system.

[0053] The filling pipe B311 is mainly used to fill cooling water into the cooling channel 307. A plurality of filling pipes B311 may be provided according to usage conditions, so as to indirectly adjust the distance between two adjacent annular partition plates 308 by the amount of cooling water, that is, indirectly adjust the thread distance between the threaded spiral attached tubes 310, thereby changing the cooling temperature at the local position.

[0054] For further examples, please refer to Figures 3 to 5 ; Figures 8 to 10 As shown: the channel interference factor processing component 4 is used to ensure the stable circulation of cooling water. The channel interference factor processing component 4 includes a plug-in slot 401 equidistantly provided on the liquid filling tube A306, an auxiliary sheet 402 is provided on one side of the liquid filling tube A306, a through hole 403 is provided on the auxiliary sheet 402, a thermal isolation sleeve 404 is equidistantly fixedly connected to the auxiliary sheet 402, a magnetic rod 405 is inserted in the thermal isolation sleeve 404, and a filter chamber 406 is provided in the liquid filling tube A306. 6. The outer ring wall of the filling tube A306 is fixedly connected to an external shell 407, and a driving tooth 408 is fixedly connected to the external shell 407 through a motor. An annular groove is provided in the inner cavity of the filling tube A306, and a driven gear disc 409 is rotatably connected in the annular groove of the filling tube A306. The driving tooth 408 is meshed with the driven gear disc 409, and a sintered metal fiber felt filter element 410 is fixedly connected to the driven gear disc 409. The filling tube A306 is fixedly connected to an automatic drain valve 411.

[0055] Wherein: the channel interference factor processing component 4 is used to ensure the stable circulation of cooling water.

[0056] The plug-in slot 401 and the thermal isolation sleeve 404 are matched.

[0057] The auxiliary piece 402 can be fastened to the liquid filling tube A306 by screws.

[0058] The external pipeline can transport cooling water to the liquid filling pipe A306 through the opening 403.

[0059] The heat isolation sleeve 404 is mainly used to prevent the cooling water carrying the temperature from affecting the magnetic magnet rod 405, causing the magnet rod 405 to be demagnetized and difficult to absorb impurities and rust in the water.

[0060] The rotating sintered metal fiber felt filter element 410 can make the distribution of impurities on the filter element surface more uniform, avoiding excessive accumulation of impurities in a certain area and blocking the cooling water inflow channel. At the same time, the rotating motion can generate centrifugal force, which helps to remove larger particle impurities adsorbed on the filter element surface, making it less likely to block the pores of the filter element.

[0061] In the cooling channel, the coolant absorbs the heat of the mold, that is, the column cavity 304, flows out from the outlet after the temperature rises, returns to the coolant tank for cooling, and then is circulated again by the circulating pump to form a circulating cooling system; during the circulation process, the automatic drain valve 411 of the filter chamber 406 will automatically detect the blockage of the filter element according to the pressure difference and drain the sewage in time to ensure the normal operation of the filtration system.

[0062] When the pressure difference in the filter chamber 406 reaches a certain value, it means that the sintered metal fiber felt filter element 410 is seriously clogged, and the automatic drain valve 411 opens to discharge the filtered impurities. At the same time, a liquid level sensor can be equipped to prompt the user to add coolant or check the filter system when the liquid level is too low.

[0063] The working principles of all the contents in the above embodiments are as follows: in the initial state: the telescopic rod 303 has not started working, the cooling channel 307 is filled with cooling water, the annular partition plates 308 in the cooling channel 307 are equidistantly distributed, the auxiliary plate 402 is fastened to the liquid filling tube A306, the magnetic rod 405 is inserted into the filter chamber 406, the driving tooth 408 has not started working, and the automatic sewage valve 411 has not performed sewage discharge work.

[0064] The following is the working process of the multi-type cooling adapter assembly 3: When in use, the cooling system composed of the liquid filling pipe A306, the transfer arc tube 309, the spiral attachment tube 310, the external circulation pump, and the cooling box will circulate the cooling water. Figure 6 The resin will be poured into the stamping molding cavity 305, and the upper mold 302 on the bottom of the upper plate 301 will enter the stamping molding cavity 305, so as to cooperate with the column cavity 304 to perform model processing on the resin solution poured into the stamping molding cavity 305. During this process, the cooling water in the cooling channel 307 and the cooling water passing through the spiral attached tube 310 spirally arranged in the cooling channel 307 will take away the temperature generated by the resin at this time, and finally circulate back to the coolant tank for cooling, and then be circulated again by the circulating pump to form a circulating cooling system, thereby providing cooling assistance for piston manufacturing.

[0065] Furthermore, if after the manufacturing of a batch of pistons of a certain shape is completed, it is necessary to manufacture another batch of pistons of another shape; for example, this piston requires weak cooling at the upper part and strong cooling at the lower part during manufacturing; at this time, there is no need to replace the column cavity 304, only the upper mold 302 on the upper plate 301 needs to be adjusted, and the spiral attachment tube 310 in the cooling channel 307 needs to be adjusted to a suitable position; specifically, since it is known that a plurality of liquid filling tubes B311 can be provided according to usage conditions, the distance between two adjacent annular partition plates 308 can be indirectly adjusted by the amount of cooling water, that is, the thread distance between the threaded spiral attachment tubes 310 can be indirectly adjusted, and the The cooling temperature of the local position changes; therefore, at this time, the operator only needs to extract the cooling water in the cooling channel 307 through the filling pipe B311 at the upper part of the column cavity 304, and then fill the cooling water into the cooling channel 307 from the filling pipe B311 at the lower part of the column cavity 304. At this time, the originally equidistantly distributed annular partition plates 308 will be transformed into a state in which the spacing from bottom to top in the cooling channel 307 gradually decreases. Furthermore, the thread pitch of the spiral attachment tube 310 fixedly connected to the annular partition plate 308 will also undergo the same change. At this point, a new mold cooling system is generated, and it is adapted to meet the manufacturing cooling requirements of the new piston.

[0066] Furthermore, on the basis of the fixed cooling channel 307, a spiral attached tube 310 for circulating cooling water is added, and the thread distance between the spiral attached tubes 310 can be flexibly adjusted according to the needs. This design can accurately control the local temperature during the overall cooling work and the manufacturing process of the phenolic resin piston: by adjusting the thread distance between the spiral attached tubes 310, the cooling intensity of different areas of the mold can be accurately adjusted. For example, in the case where the bottom of the piston needs strong cooling and the upper part needs weak cooling, the density of the bottom spiral attached tube 310 can be accurately increased, that is, the thread distance of the spiral attached tube 310 is reduced to strengthen the cooling, and the spacing of the upper spiral attached tube 310 is increased to reduce the cooling intensity; this effectively solves the problem that the existing fixed cooling method is difficult to meet the differentiated cooling needs of complex-shaped pistons, and ensures that the resin curing speed and shrinkage degree of each part of the piston during the molding process are more uniform, thereby greatly reducing the internal stress concentration caused by uneven cooling, significantly reducing the risk of cracks on the surface or inside of the piston, and greatly improving the quality and reliability of the piston, so that it can better adapt to various harsh working environments.

[0067] Improve dimensional accuracy: Due to the ability to achieve precise local cooling control, the problem of large differences in shrinkage in different parts caused by uneven cooling is effectively avoided, so that the final molding size of the piston can more accurately meet the design requirements, effectively improve the assembly accuracy of the piston and cylinder matching parts, ensure the performance stability and smooth operation of the entire equipment, reduce equipment failures and maintenance costs caused by poor assembly, and improve the overall service life and work efficiency of the equipment.

[0068] Extend mold service life: Accurate cooling control and good cooling efficiency help reduce thermal stress damage to the mold caused by excessive temperature or excessive temperature fluctuations, reduce thermal fatigue of the mold material, effectively extend the mold service life, and reduce mold replacement frequency and maintenance costs.

[0069] Furthermore, through the overall design of the multi-type cooling adapter assembly 3, the cooling efficiency and stability can be effectively improved; the contact area and heat exchange path between the cooling medium and the mold are increased in the spiral attached tube 310 through which cooling water can circulate, and the cooling efficiency is significantly improved without changing the basic structure of the original cooling system; even in a long-term continuous production process, the temperature of the mold can be stably maintained within a reasonable range, avoiding the problems of incomplete curing of phenolic resin and difficulty in demolding due to insufficient cooling, reducing the defective rate of products, improving the production qualification rate of products, and reducing the waste of resources and cost increase caused by product quality problems.

[0070] In addition, the adaptability and flexibility of the cooling system are enhanced; the adjustable thread distance of the spiral attachment tube 310 enables the cooling system to quickly adapt to phenolic resin piston manufacturing molds of different shapes and different cooling requirements. Whether it is the production of high-performance pistons with special structures or conventional standard pistons, the cooling component can optimize the cooling strategy through simple thread distance adjustment, without the need to redesign and manufacture the cooling water flow channel for each new piston shape like traditional fixed cooling molds, which greatly shortens the mold development cycle, reduces mold manufacturing costs, and improves the company's production efficiency and market adaptability.

[0071] Please refer to the above working process Figures 1 to 3 , Figures 5 to 7 .

[0072] The following is the working process of the channel interference factor processing component 4: Furthermore, during the period when the circulating pump is pumping cooling water, the cooling water entering the filter chamber 406 through the port 403 will first be filtered by the sintered metal fiber felt filter element 410 before entering the sintered metal fiber felt filter element 410, and then enter the spiral attachment tube 310 through the filling pipe A306 and the transfer arc tube 309. During this process, the thermal isolation sleeve 404 inserted in the plug-in slot 401 will absorb the rust impurities in the filter chamber 406 under the action of the magnetic rod 405 therein. Furthermore, the drive gear 404 in the external shell 407 08 will rotate with the sintered metal fiber felt filter element 410 through the driven gear disc 409 under the drive of the motor. The above designs can effectively improve the treatment of impurities in cooling water; further, in the circulation process, the automatic drain valve 411 of the filter chamber 406 will automatically detect the blockage of the filter element according to the pressure difference and discharge the sewage in time to ensure the normal operation of the filtration system. When the pressure difference in the filter chamber 406 reaches a certain value, it means that the sintered metal fiber felt filter element 410 is seriously blocked, and the automatic drain valve 411 opens to discharge the filtered impurities; as for the rust adsorbed on the outer surface of the thermal isolation sleeve 404, it can be disassembled and processed regularly.

[0073] Furthermore, by adopting a rotating design for the sintered metal fiber felt filter element 410 and adding a magnet rod 405, the impurity filtering performance can be effectively improved; that is, the rotating design of the sintered metal fiber felt filter element 410 breaks the limitations of traditional static filtration. During the rotation process, the adsorption distribution of impurities on the surface of the filter element is more uniform, effectively avoiding the premature clogging of the filter element caused by excessive accumulation of impurities in local areas; at the same time, the centrifugal force generated by the rotation can cause larger particles of impurities to leave the surface of the filter element, further reducing the risk of filter element clogging, extending the service life of the filter element, and reducing the maintenance cost and downtime of frequent replacement of the filter element.

[0074] The insertion of the magnetic rod 405 plays an adsorption role on the magnetic impurities in the cooling water, such as iron filings; these magnetic impurities are often difficult to be effectively removed by conventional filtering methods, but the magnetic rod 405 can accurately capture them, preventing them from entering the cooling channel 307 and the spiral attached tube 310 and causing adverse consequences such as wear, blockage and affecting heat conduction; through the synergistic effect with the rotating filter element, multi-directional and efficient interception of impurities in the cooling water is achieved, which greatly improves the cleanliness of the cooling water, ensures the stable operation of the cooling system, and provides reliable cooling guarantee for piston manufacturing.

[0075] At the same time, the cooling effect and piston quality are optimized; that is, due to the significant improvement in the filtering effect, impurities in the cooling water cannot interfere with the normal heat exchange function of the channel. This allows all parts of the mold to be cooled evenly and efficiently according to the predetermined cooling strategy, effectively avoiding local cooling anomalies caused by impurities; thereby ensuring that the curing process of phenolic resin in the mold is uniform and stable, greatly reducing the internal stress concentration of the piston caused by uneven cooling. The probability of quality problems such as surface cracks, deformation, and dimensional deviations in the piston is significantly reduced, and the mechanical strength, wear resistance, and dimensional accuracy of the piston are improved, ensuring that the piston can operate stably and reliably under various complex working conditions, and improving the overall quality and performance of the piston product.

[0076] Furthermore, through the overall design of the channel interference factor processing component 4, the cooling water is filtered when entering the cooling area, and the cooling water flow through the channel is prevented from being blocked during the overall cooling work and the phenolic resin piston manufacturing process, thereby ensuring cooling uniformity: this component can effectively avoid impurities from being deposited in the cooling channel 307 and the inner wall of the spiral attachment tube 310 to cause blockage problems; that is, since the cooling water flow route is always kept unobstructed, the cooling capacity of each area of ​​the mold can be stably maintained, and the uneven cooling caused by partial channel blockage is completely eliminated; this enables the phenolic resin piston to solidify and shrink evenly in various parts during the manufacturing process, greatly reducing the internal stress caused by uneven cooling, effectively preventing cracks on the surface or inside of the piston, and significantly improving the quality and reliability of the piston, ensuring its stable operation under various working conditions.

[0077] Improve cooling efficiency and ensure production efficiency: Unfiltered cooling water impurities will adhere to the wall of the cooling water channel, forming a thermal resistance layer and reducing the heat exchange efficiency. This component isolates and removes impurities through the sintered metal fiber felt filter element 410, ensuring the smoothness and thermal conductivity of the cooling water flowing through the cooling channel 307 and the spiral attached tube 310, so that the cooling system can efficiently take away the heat from the mold; this not only speeds up the curing speed of phenolic resin, shortens the molding cycle of the piston, and increases the output per unit time, but also reduces the need to extend the cooling time or perform additional operations for secondary cooling due to insufficient cooling, thereby effectively improving the overall production efficiency and ensuring that more high-quality piston products can be produced in the same time; at the same time, since the cooling water flow channel is effectively prevented from being blocked, the mold does not need to be frequently cleaned, repaired or replaced due to blockage; this significantly reduces the maintenance cost of the mold, including labor costs, maintenance material costs, and production line downtime losses caused by mold maintenance.

[0078] Please refer to the above working process Figures 3 to 5 ; Figures 8 to 10 .

[0079] Furthermore, through the coordinated design of the spiral attachment tube 310 and the channel interference factor processing component 4, the risk and cost of mold scrapping can be reduced in the field of phenolic resin piston manufacturing molds: when the cooling water flows through the channel of the traditional mold and is blocked, since its channel is often constructed by directly grooving on the mold, once the blockage occurs and it is difficult to clean and repair, the entire mold has to be scrapped, which undoubtedly brings huge economic losses to the company, including the manufacturing cost of the mold, the loss of production stagnation due to the scrapping of the mold, and the purchase cost of the new mold; and the replaceable feature of the spiral attachment tube 310 in the present invention makes it possible to replace the spiral attachment tube 310 component in a targeted manner when a problem occurs with the related part, without scrapping the entire mold; this greatly reduces the risk of mold scrapping, effectively reduces the high cost caused by mold scrapping, and significantly improves the economy of mold use and resource utilization.

[0080] In addition, the mold maintenance efficiency and production continuity can be improved: in the existing integrated cooling mold design, the maintenance work after the cooling water flow through the channel is blocked is complicated and time-consuming, and often requires a long period of downtime for processing, which seriously affects the continuity and efficiency of production; and the spiral attachment tube 310 and the channel interference factor processing component 4 of the present invention cooperate with each other to make the mold maintenance work more convenient and efficient; when the spiral attachment tube 310 parts need to be replaced or maintained, its replaceable design can quickly realize the disassembly and installation of the parts, greatly shortening the mold maintenance time. At the same time, since there is no need to carry out large-scale maintenance or replacement of the entire mold, the production line can resume normal production more quickly, reducing the production interruption time caused by mold maintenance, and improving production continuity and overall production efficiency.
