Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically a drawer-type cooling water channel and cam-driven automobile engine guard plate mold. Background Technology

[0002] The car engine, the heart of the vehicle, provides power and determines its performance, fuel economy, stability, and environmental friendliness. An engine skid plate is an accessory designed to protect the engine. Its primary function is to prevent mud from accumulating on the engine, and secondly, it protects the engine from damage caused by impacts from uneven road surfaces during driving. Through a series of design features, it aims to extend the engine's lifespan and prevent breakdowns due to external factors. Car engine skid plates are typically manufactured using pressing molds.

[0003] Currently, traditional automotive engine guard plate molds often embed cooling pipes directly inside the mold. When the cooling pipes malfunction, maintenance personnel need to disassemble the mold extensively to troubleshoot the problem. This process is complex, time-consuming, and labor-intensive, severely impacting production efficiency.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a drawer-type cooling water channel and cam-driven automobile engine guard plate mold. Utility Model Content

[0005] The purpose of this invention is to provide a drawer-type cooling water circuit and cam-driven automotive engine guard plate mold to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drawer-type cooling water circuit and cam-driven automotive engine guard plate mold, comprising a housing and a moving mold. A spring is provided in the groove in the middle of the housing, and a roller bracket is provided on the top of the spring. The moving mold is located at the bottom of the roller bracket, and a fixed mold is provided inside the lower part of the housing. Guide pillars are provided at the four corners of the top of the fixed mold, and a cooling mechanism is provided in the accommodating cavity inside the moving mold and the fixed mold. The cooling mechanism includes a heat dissipation cavity, a cooling water circuit, a cooling water pump, an extraction pipe, a coolant tank, a first delivery pipe, and a second delivery pipe. The cooling water circuit is provided in the heat dissipation cavity. The inlet and outlet of the cooling water circuit are respectively connected to the cooling water pump and the coolant tank. The other end of the cooling water pump is connected to the extraction pipe, and the other end of the cooling water circuit is connected to the first delivery pipe. The second delivery pipe is connected below the surface of the coolant tank.

[0007] Furthermore, a servo motor is installed on the right side of the back of the housing, and the output end of the servo motor is connected to a drive rod.

[0008] Furthermore, bevel gear one and bevel gear two are sequentially fitted and fixed on the outside of the drive rod from right to left, and bevel gear three is connected to the outside of both bevel gear one and bevel gear two.

[0009] Furthermore, a transmission rod is inserted through the middle of the bevel gear three, and a cam is fixedly fitted around the outside of the transmission rod. The transmission rod is located inside the bearing at the opening on the back of the housing.

[0010] Furthermore, a roller is mounted on the top of the roller bracket, and the cam and the roller are in close contact, with the same number of cams and rollers.

[0011] Furthermore, the roller bracket is elastically connected to the housing via a spring, and the roller bracket has a cross-shaped structure.

[0012] Furthermore, the roller supports are symmetrically distributed about the top center of the moving mold, and guide grooves adapted to the diameter of the guide posts are provided at the four corners of the bottom of the moving mold.

[0013] This utility model provides a drawer-type cooling water channel and cam-driven automotive engine guard plate mold, which has the following beneficial effects:

[0014] 1. The cooling mechanism of this utility model adopts a drawer-type structure. Dovetail sliders are provided on both sides of the heat dissipation cavity, which cooperate with the dovetail guide rails in the cavity of the moving mold and the fixed mold. A sealing ring is installed between the slider and the guide rail to ensure reliable sealing after the cooling mechanism is inserted. When the cooling mechanism fails, the maintenance personnel do not need to disassemble the moving mold and the fixed mold extensively. They only need to pull out the dovetail sliders on both sides of the heat dissipation cavity along the dovetail guide rail to repair or replace the corresponding cooling mechanism. This greatly simplifies the maintenance process, shortens the maintenance time, reduces labor costs, and improves production efficiency.

[0015] 2. This utility model uses a servo motor to drive the drive rod, bevel gear one, and bevel gear two to rotate, which in turn causes bevel gear three, transmission rod, and cam to rotate. The cam's convex part contacts the roller, causing the roller support to move longitudinally, which drives the moving mold and the fixed mold to close. Since the moving mold and the fixed mold are guided and positioned by guide pillars and guide grooves, they can accurately fit together during the mold closing process, thus ensuring the dimensional accuracy of the product.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 3 As shown, a drawer-type cooling water channel and cam-driven automotive engine guard plate mold includes a housing 1 and a moving mold 12. A spring 11 is installed in a groove in the middle of the housing 1, and a roller bracket 10 is installed on the top of the spring 11. The roller brackets 10 are symmetrically distributed about the top center of the moving mold 12, and guide grooves adapted to the diameter of guide posts 14 are provided at the four corners of the bottom of the moving mold 12. The moving mold 12 is located at the bottom of the roller brackets 10, and a fixed mold 13 is installed at the lower part of the interior of the housing 1. Guide posts 14 are provided at the four corners of the top of the fixed mold 13, and a cooling mechanism 15 is installed in the receiving cavity inside the moving mold 12 and the fixed mold 13. The cooling mechanism 15 includes a heat dissipation cavity 1501, a cooling water passage 1502, a cooling water pump 1503, an extraction pipe 1504, a coolant tank 1505, a first delivery pipe 1506, and a second delivery pipe 1507. The heat dissipation cavity 1501 is provided with a cooling water passage 1502. The inlet and outlet of the cooling water passage 1502 are respectively connected to the cooling water pump 1503 and the coolant tank 1505. The other end of the cooling water pump 1503 is connected to the extraction pipe 1504. The other end of the cooling water passage 1502 is connected to the first delivery pipe 1506. The second delivery pipe 1507 is connected to the lower surface of the coolant tank 1505.

[0023] The specific operation is as follows: the cooling mechanism 15 adopts a drawer-type structure, and the heat dissipation cavity 1501 is provided with dovetail sliders on both sides, which cooperate with the dovetail guide rails in the cavity of the moving mold 12 and the fixed mold 13. A sealing ring is installed between the slider and the guide rail to ensure reliable sealing after the cooling mechanism 15 is inserted. When the cooling mechanism 15 fails, the maintenance personnel do not need to disassemble the moving mold 12 and the fixed mold 13 extensively. They only need to pull out the dovetail sliders on both sides of the heat dissipation cavity 1501 along the dovetail guide rail to repair or replace the corresponding cooling mechanism 15. This greatly simplifies the maintenance process, shortens the maintenance time, reduces labor costs, and improves production efficiency.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a servo motor 2 is installed on the right side of the back of the housing 1, and the output end of the servo motor 2 is connected to a drive rod 3. From right to left, bevel gear 1 4 and bevel gear 2 5 are sequentially fitted and fixed on the outside of the drive rod 3. Both bevel gear 1 4 and bevel gear 2 5 are connected to the outside of bevel gear 3 6. A transmission rod 7 passes through the middle of bevel gear 3 6, and a cam 8 is fitted and fixed on the outside of the transmission rod 7. The transmission rod 7 is located in the bearing at the opening on the back of the housing 1. A roller 9 is installed on the top of the roller bracket 10, and the cam 8 and the roller 9 are in close contact. The number of cams 8 and rollers 9 is the same. The roller bracket 10 is elastically connected to the housing 1 by a spring 11, and the roller bracket 10 has a cross-shaped structure.

[0025] The specific operation is as follows: the servo motor 2 drives the drive rod 3, bevel gear 1 4, and bevel gear 2 5 to rotate, which causes bevel gear 3 6, transmission rod 7, and cam 8 to rotate. The convex part of cam 8 contacts roller 9 to make roller support 10 longitudinally displace, which drives the moving mold 12 and the fixed mold 13 to close. Since the moving mold 12 and the fixed mold 13 are guided and positioned by guide post 14 and guide groove, they can accurately cooperate during the mold closing process, thus ensuring the dimensional accuracy of the product.

[0026] In summary, when using this drawer-type cooling water circuit and cam-driven automotive engine guard plate mold, the moving mold 12 and the fixed mold 13 are both made of high-strength alloy steel and have undergone heat treatment processes such as quenching and tempering, resulting in good hardness, wear resistance and strength. The parting surfaces of the moving mold 12 and the fixed mold 13 are provided with cores and cavities that match the shape of the automotive engine guard plate for forming the automotive engine guard plate. The moving mold 12 and the fixed mold 13 are machined with receiving cavities that are compatible with the cooling mechanism 15, and dovetail guide rails are installed on the inner wall of the receiving cavity. The dovetail slider of the cooling mechanism 15 is aligned with the dovetail guide rails, and the cooling mechanism 15 is smoothly inserted into the receiving cavity along the direction of the dovetail guide rails until the cooling component 4 is completely embedded in the receiving cavity.

[0027] Next, the material to be pressed is placed in the fixed mold 13. The servo motor 2 drives the drive rod 3, bevel gear 1 4, and bevel gear 2 5 to rotate, causing bevel gear 3 6, transmission rod 7, and cam 8 to rotate. The convex part of cam 8 contacts the roller 9, causing the roller bracket 10 to compress the spring 11 and move longitudinally, driving the moving mold 12 to close with the fixed mold 13. Since the moving mold 12 and the fixed mold 13 are guided and positioned by the guide post 14 and the guide groove, they can accurately fit together during the mold closing process, thus ensuring the dimensional accuracy of the product.

[0028] During the production process, the cooling water pump 1503 draws coolant from the coolant tank 1505 and then delivers it to the cooling water channel 1502 of the heat dissipation cavity 1501. The coolant circulates in the cooling water channel 1502 of the heat dissipation cavity 1501, absorbing the heat of the mold and rapidly cooling and molding the material, thereby improving production efficiency. The coolant tank 1505 is used to store coolant. The ends of the first delivery pipe 1506 and the second delivery pipe 1507, which are away from the coolant tank 1505, are connected to the existing equipment cooling tower. After absorbing heat in the cooling water channel 1502 of the heat dissipation cavity 1501, the temperature of the coolant rises, and then it flows back to the cooling tower through the first delivery pipe 1506 for cooling. After being cooled by the cooling tower, the coolant returns to the coolant tank 1505 through the second delivery pipe 1507, forming a complete coolant circulation loop, thereby ensuring the cooling effect of the mold. When the material is cooled to a certain extent, the servo motor 2 works, and the moving mold 12 and the fixed mold 13 separate.

[0029] If the cooling mechanism malfunctions, maintenance personnel do not need to disassemble the moving mold 12 and the fixed mold 13 extensively. They can simply pull out the cooling mechanism 15 along the opening of the receiving cavity to repair or replace it, which greatly simplifies the maintenance process, shortens the maintenance time, reduces labor costs, and improves production efficiency.
