Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold structure with lubrication function. Background Technology

[0002] In modern industrial production systems, molds, as core equipment for achieving mass production of products, are widely used in many fields such as automobiles, electronics, home appliances, and medical devices. Their performance and working status directly determine the precision, quality, and production efficiency of products, and play an irreplaceable role in promoting the high-quality development of the manufacturing industry.

[0003] During the long-term continuous production process of molds, the internal components of the mold, such as the mating parts of the stripper plate and the stop plate, and the moving components in the part slot, will experience friction and wear due to frequent relative movements, which will shorten the service life of the mold. To solve the above problems, adding lubricating oil during the mold production process has become a routine operation in the industry.

[0004] Lubricating oil can form a lubricating film on the friction surfaces of mold components, effectively reducing the coefficient of friction, decreasing wear on components, and extending the service life of the mold. However, the current lubrication methods used in the mold industry still have significant limitations and shortcomings. Traditional lubrication operations usually involve adding lubricating oil at the material head of the mold. This method lacks specificity and precision. Because the flow and distribution of lubricating oil inside the mold is difficult to control, the lubricating oil content in the area near the material head is too high. Meanwhile, the critical parts inside the mold that truly require lubrication, such as the mating surfaces of the stripper plate and the stop plate, and components in the part slots, are often in a state of insufficient or even no lubrication. This situation of excessive lubrication at the head and insufficient lubrication at critical parts not only results in serious waste of lubricating oil and increases the production costs of enterprises, but also means that friction and wear problems remain prominent in critical parts due to insufficient lubrication, and the service life of the mold is not effectively extended. Therefore, we need a mold structure with lubrication function. Utility Model Content

[0005] The purpose of this invention is to provide a mold structure with lubrication function to solve the problems of the traditional mold lubrication methods mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mold structure with lubrication function, including a stripper plate and a stop plate, wherein a lubrication component is provided on the inner wall of the stripper plate and a filter component is provided on the outer side of the stripper plate; The lubrication assembly includes a toothed hole, the inner wall of the stripper plate is provided with a first oil groove, the inner wall of the stop plate is provided with two first part grooves at the upper and lower positions, and the inner wall of the stop plate is provided with two second part grooves at the left and right positions, the inner wall of the stop plate is provided with a second oil groove, and the inner wall of the stop plate is provided with a sealing groove, and a sealing ring is embedded in the inner wall of the sealing groove. The filtration assembly includes a flow sensor, one end of which is threadedly connected to a mounting housing. The inner wall of the mounting housing is provided with a sealing gasket, and a filter screen placement cylinder is slidably connected to the inner wall of the mounting housing. An adsorption layer, a fine filter layer, and a coarse filter layer are slidably arranged on the inner wall of the filter screen placement cylinder from the inside to the outside. A threaded cap is threadedly connected to the outer wall of the mounting housing, and an oil pipe is threadedly connected to one side of the threaded cap through a threaded hole.

[0007] Preferably, the stripper plate forms a threaded connection structure with the flow sensor through a threaded hole, and one end of the flow sensor extends into the threaded hole to achieve the connection.

[0008] Preferably, after the stripping plate and the stop plate are assembled, the first oil tank and the second oil tank are in a connected state, and the inner walls of the first oil tank and the second oil tank are coated with a ceramic coating.

[0009] Preferably, there are two second oil grooves, which are symmetrically opened on the stop plate, and the two second oil grooves are respectively connected to the two first part grooves and the two second part grooves.

[0010] Preferably, one end of the flow sensor extends into the interior of the mounting housing and forms a threaded connection, and the end of the flow sensor abuts against the sealing gasket.

[0011] Preferably, the filter screen placement cylinder and the mounting shell form a sliding fit structure, and one end of the filter screen placement cylinder is provided with a placement groove, and the other end is provided with a through groove, and the size of the through groove is smaller than the size of the placement groove.

[0012] Preferably, the outer wall of the mounting shell is machined with external threads, and the mounting shell is threadedly connected to the threaded cover through the external threads. The inner wall of the threaded cover is provided with a convex tube, and one end of the convex tube extends into the inside of the filter screen placement cylinder and abuts against the coarse filter layer.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: First, this utility model is equipped with a lubrication assembly consisting of a first oil groove, a second oil groove, a first part groove, and a second part groove. This effectively realizes the directional delivery of lubricating oil, solving the problems of excessive lubrication at the head and insufficient lubrication at critical parts in the traditional lubrication method. When the stripper plate and the stop plate are assembled, the first oil groove and the second oil groove are connected, and the second oil groove is connected to the first part groove and the second part groove respectively. This allows the lubricating oil to be directly delivered along the oil groove channel to the mating surface of the stripper plate and the stop plate, the moving parts in the part groove, and other critical lubrication areas. This ensures that each part that needs lubrication receives sufficient and uniform lubricating oil, avoids oil waste in areas that do not need lubrication, reduces the lubricating oil procurement cost for enterprises, and keeps critical parts in a good lubrication state, reducing friction and wear between parts and extending the overall service life of the mold.

[0014] Secondly, this utility model is equipped with a filter assembly including an adsorption layer, a fine filter layer, and a coarse filter layer, which can perform multi-stage purification of the lubricating oil entering the mold, ensuring the cleanliness of the lubricating oil. Among them, the coarse filter layer can quickly filter out large particulate impurities in the oil, the fine filter layer can further intercept small impurities, and the adsorption layer can effectively adsorb harmful substances such as water and oil stains in the oil, preventing these impurities from entering the oil tank and parts tank with the lubricating oil. The lubricating film formed by the clean lubricating oil on the surface of the parts is more stable and uniform, and will not be damaged by impurities, thus avoiding the situation where impurities aggravate the wear of parts. At the same time, it also prevents the problem of impurities clogging the oil tank and causing the lubrication channel to be obstructed. By setting up a flow sensor, the delivery flow of the lubricating oil can be monitored in real time. When abnormal situations such as low flow or flow interruption occur, the staff can promptly detect and troubleshoot the fault, such as oil pipe blockage or filter layer blockage.

[0017] 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.

[0018] like Figure 1-5 As shown, a mold structure with lubrication function includes a stripper plate 1 and a stop plate 2. The inner wall of the stripper plate 1 is provided with a lubrication component 3, and the outer side of the stripper plate 1 is provided with a filter component 4. The lubrication assembly 3 includes a toothed hole 301, a first oil groove 302 is provided on the inner wall of the stripper plate 1, two first part grooves 304 are provided on the upper and lower positions of the inner wall of the stop plate 2, and two second part grooves 305 are provided on the left and right positions of the inner wall of the stop plate 2, a second oil groove 303 is provided on the inner wall of the stop plate 2, and a sealing groove 306 is provided on the inner wall of the stop plate 2, and a sealing ring 307 is embedded in the inner wall of the sealing groove 306. The filter assembly 4 includes a flow sensor 401, one end of which is threadedly connected to a mounting housing 402. A sealing gasket 403 is provided on the inner wall of the mounting housing 402, and a filter screen placement cylinder 404 is slidably connected to the inner wall of the mounting housing 402. An adsorption layer 405, a fine filter layer 406, and a coarse filter layer 407 are slidably arranged on the inner wall of the filter screen placement cylinder 404 from the inside to the outside. A threaded cap 408 is threadedly connected to the outer wall of the mounting housing 402, and an oil pipe 410 is threadedly connected to one side of the threaded cap 408 through a threaded hole 409.

[0019] Through the above technical solutions, by setting a sealing groove 306 and a sealing ring 307 on the inner wall of the stop plate 2, the sealing performance of the stripper plate 1 and the stop plate 2 after assembly is enhanced, preventing lubricating oil leakage. By setting a sealing gasket 403 on the inner wall of the mounting housing 402, the sealing performance of the connection between the flow sensor 401 and the mounting housing 402 is enhanced, preventing lubricating oil leakage. By opening a groove with a sealing ring on the outer side of the mounting housing 402, when the threaded cover 408 is threaded onto the mounting housing 402, the threaded cover 408 abuts against the sealing ring, enhancing the sealing performance and preventing lubricating oil leakage. By setting a protruding tube on the threaded cover 408 to abut against the coarse filter layer 407, the sliding of the coarse filter layer 407 is prevented, enhancing stability. Qualitatively, this comprehensive sealing design solves the problem of easy leakage in traditional mold lubrication systems. It avoids the waste caused by lubricating oil leakage and prevents the leaked oil from contaminating the mold, products, and production environment. The filter assembly 4 adopts a structure in which the mounting shell 402 and the threaded cover 408 are threadedly connected, and the filter screen placement cylinder 404 is slidably engaged with the mounting shell 402. The operator only needs to unscrew the threaded cover 408 to easily remove the filter screen placement cylinder 404 and replace or clean the adsorption layer 405, the fine filter layer 406, and the coarse filter layer 407. The entire maintenance process is simple and convenient to operate, without the need to disassemble the complex mold structure, which shortens the maintenance time and reduces the maintenance difficulty and labor costs.

[0020] Specifically, the stripper plate 1 is connected to the flow sensor 401 by a threaded connection structure through the threaded hole 301, and one end of the flow sensor 401 extends into the threaded hole 301 to achieve connection.

[0021] Through the above technical solution, the threaded connection structure ensures that the flow sensor 401 is firmly connected to the stripper plate 1 by the threaded hole 301, avoiding loosening of the connection due to vibration during mold operation. The flow sensor 401 can monitor the flow rate of lubricating oil entering the stripper plate 1, allowing the operator to monitor the flow rate of lubricating oil delivered to the stripper plate 1 in real time. Once an abnormal flow occurs, it can be detected immediately, and problems such as blockage of oil pipe 410 can be investigated in time to prevent lubrication failure of the mating part between the stripper plate 1 and the stop plate 2 due to insufficient lubricating oil supply. There are two threaded holes 301, which are symmetrically opened on the stripper plate 1 to facilitate the connection of two filter components 4.

[0022] Specifically, after the stripper plate 1 and the stop plate 2 are assembled, the first oil tank 302 and the second oil tank 303 are connected, and the inner walls of the first oil tank 302 and the second oil tank 303 are coated with ceramic coating.

[0023] Through the above technical solution, the interconnected structure of the oil groove after the stripper plate 1 and the stop plate 2 are assembled creates a continuous conveying channel for lubricating oil inside the mold. This allows the lubricating oil to flow smoothly from the first oil groove 302 of the stripper plate 1 into the second oil groove 303 of the stop plate 2, laying the foundation for subsequent oil supply to key parts. The ceramic coating on the inner wall of the oil groove, due to the excellent smoothness and wear resistance of the ceramic material, serves two purposes: firstly, it reduces the frictional resistance of the lubricating oil flowing in the oil groove, making the oil delivery smoother and preventing oil stagnation caused by the roughness of the inner wall of the oil groove, thus ensuring timely lubrication; secondly, it enhances the wear resistance of the inner wall of the oil groove, preventing damage to the inner wall of the oil groove caused by oil scouring or impurity friction during long-term use, thereby extending the service life of the oil groove.

[0024] Specifically, there are two second oil grooves 303, which are symmetrically arranged on the stop plate 2, and the two second oil grooves 303 are respectively connected to the two first part grooves 304 and the second part groove 305.

[0025] Through the above technical solution, the connection structure between the second oil groove 303 and the first part groove 304 and the second part groove 305 can guide the lubricating oil to the moving components in the part groove, ensuring that all the part grooves that need lubrication on the stop plate 2 can get sufficient lubricating oil and the oil supply is uniform, thus solving the problem of insufficient lubrication of the components in the part groove under the traditional lubrication method.

[0026] Specifically, one end of the flow sensor 401 extends into the interior of the mounting housing 402 and forms a threaded connection, and the end of the flow sensor 401 abuts against the sealing gasket 403.

[0027] Through the above technical solution, by designing the end of the flow sensor 401 to abut against the sealing gasket 403, the elastic deformation of the sealing gasket 403 can fill the gap between the flow sensor 401 and the mounting housing 402, ensuring the sealing and connection stability of the connection between the flow sensor 401 and the mounting housing 402, preventing lubricating oil from leaking from the connection gap between the flow sensor 401 and the mounting housing 402, and avoiding lubricating oil waste and environmental pollution.

[0028] Specifically, the filter screen placement cylinder 404 and the mounting shell 402 form a sliding fit structure, and one end of the filter screen placement cylinder 404 is provided with a placement groove, and the other end is provided with a through groove, and the size of the through groove is smaller than the size of the placement groove.

[0029] Through the above technical solution, the sliding fit structure between the filter screen placement cylinder 404 and the mounting shell 402 facilitates the quick removal or installation of the filter screen placement cylinder 404 by the staff, simplifying the replacement and cleaning of the filter layer. The coarse filter layer 407 can be made of stainless steel woven mesh, the fine filter layer 406 can be made of glass fiber filter paper, and the adsorption layer 405 can be made of activated carbon filter screen. The design of the placement groove provides a stable installation space for the adsorption layer 405, the fine filter layer 406, and the coarse filter layer 407, ensuring that the filter layers can be placed in an orderly manner. The design of the through groove size being smaller than the placement groove size can limit the filter layer and prevent it from slipping off one side of the through groove. At the same time, the through groove can also allow the filtered lubricating oil to flow out smoothly.

[0030] Specifically, the outer wall of the mounting shell 402 is machined with external threads, and the mounting shell 402 is threadedly connected to the threaded cover 408 through the external threads. The inner wall of the threaded cover 408 is provided with a convex tube, and one end of the convex tube extends into the filter screen placement cylinder 404 and abuts against the coarse filter layer 407.

[0031] Through the above technical solution, the threaded connection structure between the mounting shell 402 and the threaded cover 408 facilitates the quick disassembly and installation of the threaded cover 408 by the staff, providing convenience for the removal and installation of the filter screen placement cylinder 404; the convex tube on the inner wall of the threaded cover 408 extends into the interior of the filter screen placement cylinder 404 and abuts against the coarse filter layer 407, which can play a role in pressing and fixing the coarse filter layer 407, the fine filter layer 406, and the adsorption layer 405, preventing the filter layer from loosening or shifting during the flow of lubricating oil.

[0032] In use, first connect the external lubricating oil supply system to the oil pipes 410 of the filter components 4 on both sides of the stripper plate 1. After starting the lubricating oil supply system, the lubricating oil on both sides enters the respective mounting housings 402 simultaneously along the corresponding oil pipes 410, starting the dual-path lubrication process. The working process of the filter components 4 on both sides is the same. Taking one side as an example, the lubricating oil enters the mounting housing 402 along the oil pipe 410 and passes through the coarse filter layer 407, the fine filter layer 406, and the adsorption layer 405 in sequence. The coarse filter layer 407 intercepts large particles of impurities in the lubricating oil, the fine filter layer 406 filters fine impurities in the oil, and the adsorption layer 405 adsorbs impurities in the oil, ensuring the stability of the lubricating oil performance. The purified clean lubricating oil flows into the flow sensor through the groove at the end of the filter screen placement cylinder 404. The device 401 and the flow sensor 401 monitor the flow data of the lubricating oil in real time. The lubricating oil enters the first oil groove 302 on the stripper plate 1 through the tooth hole 301. After the stripper plate 1 and the stop plate 2 are assembled, the first oil groove 302 and the second oil groove 303 are connected, so that the oil can flow smoothly from the first oil groove 302 into the second oil groove 303 of the stop plate 2. The lubricating oil flowing into the second oil groove 303 will be distributed to each part groove simultaneously to ensure that each part that needs lubrication can obtain sufficient and uniform lubricating oil, so that the key parts are in a good lubrication state, reducing friction and wear between parts and extending the overall service life of the mold. This completes all the work. The contents not described in detail in this specification are the prior art known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
