Description

Technical Field

[0001] This utility model relates to the field of automotive molding technology, specifically an automotive engine cylinder block casting molding mold. Background Technology

[0002] With the rapid advancement of modern industrial technology, the casting industry, as an important pillar of the manufacturing industry, faces increasingly stringent challenges in terms of production efficiency, product quality, and working environment. However, in the traditional casting process, the problem of thoroughly removing dust and debris from the mold base has not been well resolved. This not only affects the smooth progress of the casting process but may also seriously impact product quality.

[0003] Upon investigation, a utility model patent discloses a casting mold for an automobile engine cylinder block (publication number: CN222740227U), including a support platform; a casting device and a dust removal device disposed on the support platform; the dust removal device includes a set of connecting plates symmetrically disposed on the inner side of the support platform; a lead screw rotating between the two connecting plates; a connecting block threaded onto the lead screw; a fan disposed on the outer side of the connecting block; an adsorption hood connected to the adsorption end of the fan; a filter box disposed on the outer side of the support platform, the exhaust end of the fan being connected to the filter box; and an activated carbon filter element disposed inside the filter box.

[0004] Although the above technical solution can remove dust and debris from the mold base by sliding the fan on one side of the mold base surface through the lead screw, it requires additional power to operate. Moreover, the fan's air intake is exposed on the outer surface. When the fan slides, the generated wind force may scatter dust and impurities at the bottom of the mold base, resulting in incomplete collection and treatment of dust and debris, and reducing the efficiency of dust and debris collection and treatment.

[0005] Therefore, this utility model provides a casting mold for automobile engine cylinder blocks to solve the above problems. Utility Model Content

[0006] This utility model provides a casting mold for an automobile engine cylinder block, which aims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A casting mold for an automobile engine cylinder block includes a base and a forming mechanism. A support frame is fixedly installed on the top of the base, and the forming mechanism is slidably installed on one side of the bottom of the support frame.

[0009] A hydraulic cylinder is fixedly installed at the top of the support frame, and a mold head is telescopically installed at the bottom of the support frame. A control panel is set on the top of the mold head.

[0010] The molding mechanism includes a worktable, a transfer plate is fixedly installed on the top of the worktable, guide rails are provided on both sides of the top of the transfer plate, a mold base is slidably installed on the top of the guide rails, a mating hole is opened on one side of the surface of the mold base, a connecting pipe is fixedly installed on one side of the surface of the transfer plate, a through hole is opened at the bottom of the connecting pipe, a filter box is fixedly installed at the bottom of the through hole, and a filter plate is movably installed inside the filter box.

[0011] The guide rails on both sides of the top of the transfer plate in the forming mechanism provide a stable sliding path for the mold base. The operator can flexibly adjust the position of the mold base along the guide rails to ensure that the mating holes on the surface of the mold base are precisely aligned with the connecting pipe of the transfer plate. This ensures that impurities and gases generated after casting can be smoothly transported to the mold base through the connecting pipe, improving material utilization and forming efficiency. The combination of the through hole at the bottom of the connecting pipe with the filter box and filter plate can filter impurities and gases during the transportation process. The filter plate intercepts impurities or foreign objects, effectively preventing impurities from entering the mold base and affecting the quality of the cylinder block casting, ensuring the casting accuracy and performance of the engine cylinder block. Furthermore, the filter plate adopts a movable installation method, which is convenient for later disassembly, cleaning or replacement, reducing the difficulty of mold maintenance and extending the overall service life of the mold.

[0012] As a preferred technical solution of this application, a servo motor is fixedly installed on one side of the material transfer plate. The mold base slides and adjusts on the guide rail surface via the servo motor, corresponding vertically to the bottom of the mold head, and slides and engages with the connecting pipe through the docking hole. The servo motor drive enables precise displacement control of the mold base on the guide rail, minimizing the vertical alignment error between the mold base and the bottom of the mold head, improving mold docking accuracy, and reducing cylinder forming defects caused by alignment deviation. At the same time, the sliding engagement of the mold base with the connecting pipe through the docking hole, under the precise drive of the servo motor, can quickly complete the coaxial docking of the two, avoiding jamming or misalignment that may occur during manual docking, and further improving the smoothness of the impurity and gas delivery channels generated after casting.

[0013] As a preferred technical solution of this application, a transmission pipe is fixedly connected to one side of the filter box, and a purification box is fixedly installed on one side of the transmission pipe. The interior of the filter box is connected to the interior of the mold base through connecting pipes, docking holes and through holes. The filter box and the purification box form a dual treatment system of filtration and purification through the transmission pipe. The filter box first intercepts solid impurities in the raw material. Subsequently, the small impurities or volatile substances that are not completely filtered can enter the purification box through the transmission pipe for further treatment, so as to avoid the residual impurities affecting the quality of the cylinder and reduce the emission of harmful substances.

[0014] As a preferred technical solution of this application, the mold head is raised and lowered at the bottom of the control panel by a hydraulic cylinder and is engaged with the top of the mold base. This drives the mold head to rise and fall at a uniform speed, avoiding impact when the mold head and mold base are connected due to uneven lifting speed. This protects the mold components and reduces defects such as cracks and pores in the cylinder casting caused by impact. It also enables quick and stable connection between the mold head and mold base, reduces the difficulty of operation, and improves the efficiency of molding preparation.

[0015] As a preferred technical solution of this application, the purification box is fixedly installed at the bottom of the base and is connected to the inside of the filter box through a transmission pipe. The transmission pipe is located on one side of the filter box near the bottom. The fact that the transmission pipe is located near the bottom of the filter box ensures that the sedimented impurities and the processed materials in the filter box can smoothly enter the transmission pipe, avoiding material accumulation or residue at the bottom of the filter box and improving filtration and transmission efficiency.

[0016] As a preferred technical solution of this application, there are three filter plates, which are evenly distributed inside the filter box. The filter plates on the upper and lower sides are connected to the through holes and the transmission pipes respectively, ensuring that impurities and gases can pass through each level of filter plates along the preset path in sequence, avoiding impurities and gases from being directly transported around the filter plates, ensuring that each stage of filtration can play its full role, and further enhancing the stability of the filtration effect.

[0017] As a preferred technical solution of this application, the filter box is fixedly installed on one side of the bottom of the workbench and is vertically connected to the connecting pipe. The vertical connection between the filter box and the connecting pipe allows impurities and gas to fall naturally in the vertical direction when they enter the filter box from the connecting pipe, without changing the conveying direction, reducing the retention or blockage of impurities and gas in the pipeline, and improving the conveying efficiency.

[0018] The beneficial effects of this utility model are as follows:

[0019] The guide rail on the top of the transfer plate in the forming mechanism provides a stable sliding path for the mold base. With the precise drive of the servo motor on one side of the transfer plate, the vertical and precise alignment of the mold base and the bottom of the mold head can be achieved. At the same time, the mold base can quickly complete the coaxial connection with the connecting pipe through the docking hole, reducing the alignment deviation and reducing the cylinder forming defects caused by inaccurate docking. In addition, the precise connection between the connecting pipe and the mold base ensures that impurities and gases generated during the casting process can be smoothly transported, avoiding the retention and waste of impurities and gases, and improving the utilization rate of impurities and gases.

[0020] The combination design of the bottom through hole of the connecting pipe with the filter box and filter plate forms a reliable filtration system. The three evenly distributed filter plates constitute a multi-stage filtration structure. The filter plates on the upper and lower sides are also connected to the through hole and the transmission pipe respectively, ensuring that impurities and gases are fully filtered along the preset path, effectively intercepting impurities and foreign objects of different particle sizes, preventing them from entering the mold base and affecting the purity of the cylinder block casting, and ensuring the casting precision and performance of the engine cylinder block.

[0028] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0029] This utility model provides a casting mold for an automobile engine cylinder block, such as... Figure 1-4 As shown, it includes a base 100 and a molding mechanism 200. A support frame 101 is fixedly installed on the top of the base 100, and the molding mechanism 200 is slidably installed on one side of the bottom of the support frame 101.

[0030] A hydraulic cylinder 102 is fixedly installed on the top of the support frame 101, and a mold head 104 is telescopically installed on the bottom of the support frame 101. A control panel 103 is provided on the top of the mold head 104.

[0031] The molding mechanism 200 includes a workbench 201, a transfer plate 202 fixedly installed on the top of the workbench 201, guide rails 204 provided on both sides of the top of the transfer plate 202, a mold base 205 slidably installed on the top of the guide rails 204, a mating hole 206 opened on one side of the surface of the mold base 205, a connecting pipe 207 fixedly installed on one side of the surface of the transfer plate 202, a through hole 211 opened at the bottom of the connecting pipe 207, a filter box 208 fixedly installed at the bottom of the through hole 211, and a filter plate 212 movably installed inside the filter box 208.

[0032] The guide rails 204 on both sides of the top of the transfer plate 202 in the forming mechanism 200 provide a stable sliding path for the mold base 205. The operator can flexibly adjust the position of the mold base 205 along the guide rails 204 so that the mating hole 206 on the surface of the mold base 205 is precisely aligned with the connecting pipe 207 of the transfer plate 202. This ensures that impurities and gases generated after casting can be smoothly transported to the mold base 205 through the connecting pipe 207, improving material utilization and forming efficiency. The combination of the bottom through hole 211 of the connecting pipe 207 with the filter box 208 and the filter plate 212 can filter impurities and gases during the transportation process. The filter plate 212 intercepts impurities or foreign objects, effectively preventing impurities from entering the mold base 205 and affecting the quality of the cylinder block casting, ensuring the casting accuracy and performance of the engine cylinder block. In addition, the filter plate 212 adopts a movable installation method, which is convenient for later disassembly, cleaning or replacement, reducing the difficulty of mold maintenance and extending the overall service life of the mold.

[0033] like Figure 2 As shown, a servo motor 203 is fixedly installed on one side of the material transfer plate 202. The mold base 205 slides and adjusts on the surface of the guide rail 204 through the servo motor 203, corresponding vertically to the bottom of the mold head 104, and is slidably connected to the connecting pipe 207 through the docking hole 206. The driving method of the servo motor 203 can realize the precise displacement control of the mold base 205 on the guide rail 204, which can minimize the vertical alignment error between the mold base 205 and the bottom of the mold head 104, improve the mold docking accuracy, and reduce cylinder forming defects caused by alignment deviation. At the same time, the mold base 205 slides and connects to the connecting pipe 207 through the docking hole 206. Under the precise drive of the servo motor 203, the two can quickly complete the coaxial docking, avoiding the jamming or misalignment that may occur during manual docking, and further improving the smoothness of the impurity and gas conveying channels generated after casting.

[0034] like Figure 3As shown, a transmission pipe 209 is fixedly connected to one side of the surface of the filter box 208, and a purification box 210 is fixedly installed on one side of the surface of the transmission pipe 209. The interior of the filter box 208 is connected to the interior of the mold base 205 through the connecting pipe 207, the docking hole 206, and the through hole 211. The filter box 208 and the purification box 210 form a dual treatment system of filtration and purification through the transmission pipe 209. The filter box 208 first intercepts solid impurities in the raw materials. Subsequently, the small impurities or volatile substances that are not completely filtered can enter the purification box 210 through the transmission pipe 209 for further processing, so as to avoid the impurities remaining and affecting the quality of the cylinder, and at the same time reduce the emission of harmful substances.

[0035] like Figure 1-2 As shown, the mold head 104 is raised and lowered at the bottom of the control panel 103 by the hydraulic cylinder 102, and is engaged with the top of the mold base 205. This drives the mold head 104 to rise and fall at a uniform speed, avoiding impact when the mold head 104 and the mold base 205 are connected due to uneven lifting speed. This protects the mold components and reduces defects such as cracks and porosity in the cylinder casting caused by impact. It also enables the mold head 104 and the mold base 205 to connect quickly and stably, reducing the difficulty of operation and improving the efficiency of molding preparation.

[0036] like Figure 3 As shown, the purification box 210 is fixedly installed at the bottom of the base 100 and is connected to the interior of the filter box 208 through the transmission pipe 209. The transmission pipe 209 is located on one side of the surface of the filter box 208 near the bottom. The transmission pipe 209 is located near the bottom of the filter box 208 to ensure that the sedimented impurities and processed materials in the filter box 208 can smoothly enter the transmission pipe 209, avoiding material accumulation or residue at the bottom of the filter box 208 and improving filtration and transmission efficiency.

[0037] like Figure 4 As shown, there are three filter plates 212, which are evenly distributed inside the filter box 208. The filter plates 212 on the upper and lower sides are connected to the through holes 211 and the transmission pipe 209 respectively. This ensures that the raw materials can pass through the filter plates 212 in sequence along the preset path, avoiding impurities and gas from being directly transported around the filter plates 212. This ensures that each stage of filtration can play its full role and further enhances the stability of the filtration effect.

[0038] like Figure 3-4 As shown, the filter box 208 is fixedly installed on one side of the bottom of the workbench 201 and is vertically connected to the connecting pipe 207. The vertical connection between the filter box 208 and the connecting pipe 207 allows impurities and gas to fall naturally in the vertical direction when they enter the filter box 208 from the connecting pipe 207, without changing the conveying direction, reducing the retention or blockage of impurities and gas in the pipeline, and improving the conveying efficiency.

[0039] In summary: The servo motor 203 on one side of the material transfer plate 202 is activated. Under the precise drive of the servo motor 203, the mold base 205 slides along the guide rails 204 on both sides of the top of the material transfer plate 202 until the mold base 205 is perpendicularly aligned with the mold head 104 at the bottom of the support frame 101, completing the initial alignment of the mold base 205 and the mold head 104. Next, the hydraulic cylinder 102 on the top of the support frame 101 is controlled via the control panel 103 on the top of the mold head 104. The hydraulic cylinder 102 drives the mold head 104 to descend at a uniform speed, causing the mold head 104 to be raised and engaged on the top of the mold base 205, forming a closed casting cavity. Subsequently, the mating hole 206 on the surface of the mold base 205 aligns with the connecting pipe on the material transfer plate 202. 207 achieves sliding connection. Impurities and gases generated during the casting process enter the connecting pipe 207 through the docking hole 206 of the mold base 205, fall down the connecting pipe 207 to the through hole 211 at the bottom, and then enter the filter box 208 which is vertically connected to the connecting pipe 207. In the filter box 208, the impurities and gases first pass through three evenly distributed filter plates 212 for multi-stage filtration. Larger impurities are intercepted by the filter plates 212, while small impurities or volatile substances that are not completely filtered enter the purification box 210 fixed at the bottom of the base 100 through the transmission pipe 209 near the bottom of the filter box 208 for further purification treatment, so as to avoid the residual impurities affecting the quality of the cylinder or the emission of harmful substances.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
