Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a mold device for manufacturing an oil pan housing. Background Technology

[0002] The oil pan housing is a key component of a car engine, and its manufacturing precision and quality directly affect the engine's performance. Currently, the production of oil pan housings mainly relies on stamping or die casting using molds.

[0003] During the manufacturing of oil pan housings using stamping technology, the blanking and trimming processes generate a large amount of metal scrap. This scrap is small in size and irregular in shape, and it is easy for it to fall off and get stuck in the mold cavity, channel corners, or gaps in the guide mechanism during the high-speed opening and closing of the mold. If this residual scrap is not removed in time and effectively, it will cause pressure marks or scratches on the product surface during the next mold closing and stamping, resulting in product scrap. More seriously, the continuous accumulation of scrap may directly damage the working edge of the mold or precision parts, forcing the production line to stop for manual cleaning. This not only greatly reduces production efficiency but also increases maintenance costs.

[0004] On the other hand, for aluminum alloy oil pan housings manufactured using die casting, mold temperature control becomes a decisive factor affecting product quality and production cycle. Oil pan housings typically have complex structures with deep cavities and uneven surfaces. Therefore, a large number of sliders and core-pulling mechanisms need to be installed on the die casting mold. These complex mechanical structures occupy a large amount of internal space, making it difficult to effectively arrange traditional cooling channels in key parts of the mold, especially at the slider locking point. This makes it easy for the mold to experience localized overheating and uneven heat dissipation during continuous production. Excessively high mold temperatures can directly cause molten metal to adhere to the mold surface, resulting in material sticking and scratches, which seriously affect the product's appearance and dimensional accuracy. Furthermore, in order to wait for the mold to cool down, the production cycle has to be extended, thus limiting overall production efficiency.

[0005] Therefore, this utility model proposes a mold device for manufacturing an oil pan housing to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the mold device for manufacturing oil pan housing, such as the difficulty in automatically cleaning up waste generated during the stamping process and insufficient cooling capacity due to the complex local structure during the die casting process, this utility model aims to provide a mold device for manufacturing oil pan housing with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a mold device for manufacturing an oil pan housing, including: a lower seat, an upper seat; and a cleaning mechanism disposed on the upper seat and a cooling mechanism disposed on the lower seat.

[0010] Preferably, the adjustment plate has a groove, and the positioning rod is slidably set in the groove to achieve precise adjustment of the cleaning position.

[0011] Preferably, the adjusting plate is also provided with a sliding groove, in which a spring is provided; and the positioning rod is provided with a screw, and the adjusting plate is provided with a screw hole that cooperates with the screw. Through the cooperation of the spring, the screw, and the screw hole, the cleaning mechanism can realize the automatic rebound and storage locking functions.

[0012] Preferably, cleaning brushes are provided on both the upper and lower sides of the fixed plate to improve the cleaning coverage and efficiency of a single reciprocating motion.

[0013] Preferably, the cooling mechanism also includes a return pipe, one end of which is connected to the cooling tank and the other end is connected to the cooling bottle, thereby forming a complete closed-loop circulation circuit for the coolant.

[0014] Preferably, the cooling bottle is equipped with a filter screen to filter impurities in the coolant returning from the return pipe.

[0015] Preferably, the outer walls of both the cooling pipe and the return pipe are connected with pleats made of elastic folded tubes so that they can adapt to the stretching and compression during the mold opening and closing process.

[0016] Preferably, the cooling tank is I-shaped to increase the contact area with the mold and improve heat exchange efficiency.

[0018] 2. This utility model, through an independent closed-loop cooling mechanism located on the lower base and composed of components such as a cooling bottle, a micro pump, a flexible cooling pipe with pleats, and an I-shaped cooling groove, solves the problem that existing die-casting molds, due to structural limitations, cannot accommodate cooling water channels at positions such as the slider, resulting in insufficient local cooling capacity and excessively high temperatures in the mold, which in turn causes material sticking, scratches, and affects product quality and production efficiency.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figure 1 , Figure 2 and Figure 3 A mold device for manufacturing an oil pan housing includes a lower seat 1 and an upper seat 2 that is closable and mounted on top of the lower seat 1. The lower seat 1 and the upper seat 2 together constitute the main mold structure for manufacturing the oil pan housing. To achieve automatic cleaning and efficient cooling, the mold device also integrates a cleaning mechanism 3 and a cooling mechanism 4. The cleaning mechanism 3 is located on both sides of the outer wall of the upper seat 2 and is used to remove residual waste during mold operation. The main components of the cooling mechanism 4 are mounted on the lower seat 1 and cool the mold through forced liquid circulation. The structure of the cleaning mechanism 3 includes an adjusting plate 301 fixedly connected to the upper seat 2. The adjusting plate 301 is provided with a mating structure that allows a positioning rod 303 to move. The bottom of the positioning rod 303 is fixedly connected to... A cleaning brush 305, which is directly used to perform cleaning tasks, is mounted on a fixed plate 304. The working area of ​​the cleaning brush 305 can be adjusted by moving the positioning rod 303. The structure of the cooling mechanism 4 forms an independent coolant circulation loop. The loop includes a cooling bottle 401 for storing coolant, a micro pump 403 as a power source, a delivery pipeline, and a cooling tank 407 for heat exchange. Specifically, the cooling bottle 401 and the micro pump 403 are both fixed to the lower base 1. The outlet of the micro pump 403 is connected to the cooling pipe 406 through a connecting pipe 402. The end of the cooling pipe 406 is connected to the cooling tank 407 opened inside the mold, thereby accurately delivering the coolant to the part that needs to be cooled.

[0023] Please refer to Figure 3 and Figure 4The main structure of the cleaning mechanism 3 is fixedly connected to both sides of the outer wall of the upper seat 2. The adjusting plate 301 is fixed to the upper seat 2 by bolts. The adjusting plate 301 is provided with a sliding groove 302 and a shifting groove 306. The positioning rod 303 is slidably engaged in the sliding groove 302, thereby allowing the cleaning area to be adjusted. The bottom of the positioning rod 303 is fixedly connected to a fixing plate 304. The cleaning brush 305 for directly cleaning waste is fixedly installed on the upper and lower sides of the fixing plate 304. In order to realize the automatic rebound and storage locking of the mechanism, a spring 307 is accommodated in the shifting groove 306. The positioning rod 303 is provided with a screw 308. The adjusting plate 301 is provided with a corresponding screw hole 309. When the positioning rod 303 is pushed and the screw 308 is threadedly connected to the screw hole 309, the cleaning mechanism 3 is locked in the storage position. When the screw 308 is unscrewed, the elastic force of the spring 307 will push the positioning rod 303 to automatically rebound to the working position.

[0024] Please refer to Figure 3 The cooling mechanism 4 forms a closed liquid circulation loop. The cooling bottle 401 and the micro pump 403 are both fixedly installed on the lower seat 1. The suction port of the micro pump 403 is fluidly connected to the bottom of the cooling bottle 401. The discharge port of the micro pump 403 is connected to one end of the cooling pipe 406 through the connecting pipe 402. The other end of the cooling pipe 406 is connected to the I-shaped cooling tank 407 opened inside the mold. The outlet end of the cooling tank 407 is then connected back to the upper part of the cooling bottle 401 through the return pipe 405. In order to adapt to the movement when the mold opens and closes, the outer walls of the cooling pipe 406 and the return pipe 405 are connected with pleats 404 made of elastic folding tubes. In order to realize the recycling of coolant, a filter screen is also provided inside the cooling bottle 401 to filter impurities.

[0025] As a preferred implementation method, to achieve flexible adjustment and convenient storage of the cleaned area, please refer to... Figure 4 The structure of the cleaning mechanism 3 is further defined. The mating structure on the adjusting plate 301 is a sliding groove 302 extending along the length of the adjusting plate 301. The positioning rod 303 is installed inside the sliding groove 302 by sliding engagement, so that it can move along the path of the sliding groove 302 to change the working range of the cleaning brush 305. In order to realize the automatic rebound function, the adjusting plate 301 is also provided with a shift groove 306. The spring 307 is set inside the shift groove 306 and pre-compressed between the positioning rod 303 and the groove wall of the shift groove 306. In order to realize locking, the positioning rod 303 is integrally formed with a screw 308, and the adjusting plate 301 is provided with a corresponding screw hole 309. The cleaning mechanism 3 can be fixed in the storage state by the threaded connection between the screw 308 and the screw hole 309. In order to improve the cleaning efficiency, the cleaning brush 305 is fixedly installed on both the upper and lower surfaces of the fixing plate 304.

[0026] As another preferred embodiment, in order to achieve coolant recycling and adapt to mold movement, please refer to... Figure 3 The structure of the cooling mechanism 4 is further defined. One end of the return pipe 405 is connected to the outlet of the cooling tank 407, and the other end is connected to the cooling bottle 401, thus forming a complete closed loop together with the cooling bottle 401, the micro pump 403, the connecting pipe 402, the cooling pipe 406 and the cooling tank 407. In order to ensure the cleanliness of the circulating coolant, a filter screen is provided inside the cooling bottle 401 near the inlet of the return pipe 405. In order to ensure the reliability of the connection of the pipeline during the opening and closing of the mold, the outer walls of the cooling pipe 406 and the return pipe 405 are connected with pleats 404 made of elastic folded tubes. In order to achieve efficient heat exchange in a specific area, the cross-sectional shape of the cooling tank 407 is set as I-shaped.

[0027] Working principle: First, during the stamping process, scrap may get stuck at the corners of the channel or the edges of the cavity and cannot fall off automatically. To avoid excessive scrap accumulation leading to abnormal stamping of the mold, a cleaning mechanism 3 is specially set up. Its main body is located on both sides of the outer wall of the upper seat 2. Adjustment plates 301 are fixedly connected to both sides of the upper seat 2. The adjustment plates 301 have sliding grooves 302. The positioning rod 303 can adjust the cleaning area of ​​the cleaning component by moving on the sliding grooves 302. The bottom of the positioning rod 303 is fixedly connected to a fixing plate 304. The upper and lower sides of the fixing plate 304 are equipped with cleaning brushes 305, which are the key components for cleaning the mold. When cleaning the outer wall, the cleaning mechanism 3 needs to be stored. Simply push the positioning rod 303 to move along the outside of the sliding groove 306 until the screw 308 on the positioning rod 303 contacts the screw hole 309 and is completely fixed with the thread. When cleaning is required, a spring 307 is connected in the sliding groove 306. When the screw 308 is released from the screw hole 309, the cleaning component will automatically spring back. Furthermore, some die-casting molds do not adequately consider cooling in their structural design, and cooling channels cannot be installed at the slider locking point, resulting in insufficient mold cooling capacity. This can cause excessively high mold temperatures, leading to defects such as material sticking and scratches, affecting product quality and production efficiency. To avoid this, a cooling mechanism 4 is installed. A cooling bottle 401 is fixed to the top of the lower seat 1. When cooling of the mold interior is required, only the micro pump 403 located on the lower seat 1 needs to be activated. The micro pump 403 draws coolant from the cooling bottle 401, allowing the coolant to cool down. After passing through the connecting pipe 402 and the micro pump 403, the coolant reaches the cooling tank 407 through the cooling pipe 406. The cooling tank 407 is I-shaped. After one round of cooling is completed, the residual coolant is collected through the return pipe 405 and finally merged into the cooling bottle 401. The cooling bottle 401 is equipped with a filter screen, which can filter impurities in the residual coolant to achieve reuse and improve the utilization efficiency of the coolant. The outer walls of the cooling pipe 406 and the return pipe 405 are connected with pleats 404, which are made of folded tubes with a certain degree of elasticity to facilitate the flow of coolant during mold operation.
