Description

Technical Field

[0001] This utility model relates to the field of engine cover mold technology, specifically to an automobile engine cover mold. Background Technology

[0002] Automotive engine cover mold is a specialized piece of equipment used for the mass production of automotive engine covers (i.e., the outer covering of the engine compartment, which serves to protect the engine and enhance its appearance).

[0003] A search revealed Chinese patent application CN202322378411.1, which discloses a die-casting mold for an automobile engine hood. This invention includes a workbench with a lower mold fixedly connected to its top. The lower mold has a mold groove at its top and an installation chamber inside. A bidirectional lead screw is rotatably connected within the installation chamber. Connecting blocks are threaded to the outer walls of both ends of the bidirectional lead screw. Push rods are hinged to the tops of both sets of connecting blocks. The output shaft of a first motor drives the bidirectional lead screw to rotate. The rotating lead screw, through threaded transmission, causes both sets of connecting blocks to move simultaneously towards the center of the lead screw, which in turn drives the push rods hinged to its top to push a push plate upwards. This pushes the die-cast engine hood blank upwards, making it easier for workers to remove. This avoids situations where the die-cast engine hood blank is firmly attached to the mold groove, making it difficult for workers to remove from the lower mold, thus improving work efficiency.

[0004] In the aforementioned prior art, the movement of the upper mold downwards drives the movement of a pull plate on one side. This movement of the pull plate and the lower push plate pushes the molded engine hood blank out of the lower mold, achieving a rapid material removal effect. Although this material removal method can provide a good auxiliary effect, the use of a single pull plate to pull the push rod with the help of a snap-fit ​​mechanism, which in turn pushes the push plate upwards to squeeze the engine hood blank, results in a large force and pressure. After long-term use, the snap-fit ​​mechanism is prone to breakage, thus affecting the material removal efficiency. Utility Model Content

[0018] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: an automobile engine hood mold, including a base 1, a control box 11 fixedly connected to the upper end of one side of the base 1, and a bracket 12 fixedly connected to the end of the base 1 away from the control box 11. An electric telescopic stamping plate 13 is fixedly connected to the upper end of the bracket 12, and a lower mold 14 is provided below the electric telescopic stamping plate 13. The lower end of the lower mold 14 is fixedly connected to the base 1, and slots 15 are provided at both ends of the lower mold 14.

The lower ends of the connecting rod 21, transmission rod 22, and pressure plate 23 are inserted into the base 1. A pushing component 3 is provided on the outer side of the pressure plate 23, and an elastic component 4 is provided at the lower end of the pushing component 3. An air blowing component 5 is provided on one side of the lower mold 14, and an extraction component 6 is provided at the end of the lower mold 14 away from the air blowing component 5. A collection component 7 is provided at the end of the extraction component 6 away from the lower mold 14. When the engine hood blank stamped in the lower mold 14 is removed by the pressing component 2 and the pushing component 3, the stability is stronger and it is not easy for some parts to break due to excessive force after long-term use, thereby improving the service life. The air blowing component 5 and the extraction component 6 can also be used to clean the stamping debris remaining in the lower mold 14, improving the convenience of stamping.

[0019] like Figure 2 As shown, the pushing component 3 includes a sleeve 31 sleeved on the outside of the pressure plate 23, and a first spring 32 is fixedly connected to the upper outer end of the sleeve 31. The upper end of the first spring 32 is fixedly connected to the base 1, and the inside of the first spring 32 is sleeved on the outside of the transmission rod 22. The pressure plate 23 pushes the sleeve 31 to compress the first spring 32 while pulling the push plate 33 to move upward. The sleeve 31 moves synchronously with the elastic potential energy of the second spring 42 under the positioning of the positioning cylinder 41. Then the push plate 33 squeezes the engine cover blank in the lower mold 14 out of the lower mold 14.

[0020] like Figure 2 As shown, push plates 33 are fixedly connected to one end of the two sets of pressure plates 23, and the upper end of the push plates 33 passes through the base 1 and is inserted into the lower mold 14.

[0021] like Figure 2 As shown, the elastic component 4 includes a positioning cylinder 41 inserted into the inner side of the lower end of the pressure plate 23, and the lower end of the positioning cylinder 41 is fixedly connected to the base 1. A second spring 42 is inserted inside the positioning cylinder 41, and the lower end of the second spring 42 is fixedly connected to the base 1. The upper end of the second spring 42 is fixedly connected to the pressure plate 23. When the pressure plate 23 moves down, the second spring 42 is compressed under the positioning of the positioning cylinder 41.

[0022] like Figure 1 As shown, the air blowing assembly 5 includes a blower 51 disposed on one side of the slot 15, and a first connecting end 52 is fixedly connected to the end of the blower 51 near the lower mold 14. The first connecting end 52 is fixedly connected to the lower mold 14 at the end near the lower mold 14. When the blower 51 is started, external air is drawn out, and the drawn air is discharged through the first connecting end 52 and injected into the lower mold 14 through the slot 15.

[0023] like Figure 1 As shown, the extraction component 6 includes a second connecting end 61 fixedly connected to the lower mold 14 at the end away from the first connecting end 52, and an air pump 62 fixedly connected to the second connecting end 61 at the end away from the lower mold 14. A delivery pipe 63 is fixedly connected to one side of the air pump 62. The air pump 62 extracts the airflow flowing inside the lower mold 14 through the second connecting end 61, thereby allowing the airflow to carry away the residual debris inside the lower mold 14.

[0024] like Figure 1 As shown, the collection assembly 7 includes a collection box 71 fixedly connected to the end of the delivery pipe 63 away from the air pump 62, and a filter screen 72 is fixedly connected to the upper end of the collection box 71 by bolts. A cover plate 73 is rotatably connected to the end of the collection box 71 away from the delivery pipe 63, and the lower end of the collection box 71 is fixedly connected to the base 1. The extracted airflow carries debris into the collection box 71 through the delivery pipe 63 for storage, while the airflow is filtered through the filter screen 72 and discharged. The debris remains in the collection box 71, and the cover plate 73 can be opened later to clean the debris stored in the collection box 71.

[0025] Working principle: When the engine hood blank stamped in the lower mold 14 is removed, the electric telescopic stamping plate 13 retracts, causing the connecting rod 21 to move upward. After the connecting rod 21 moves upward, it pulls the transmission rod 22 and the pressure plate 23 upward. Then, the pressure plate 23 pushes the sleeve 31 to compress the first spring 32, while simultaneously pulling the push plate 33 upward. The sleeve 31, under the positioning of the positioning cylinder 41, moves synchronously with the elastic potential energy of the second spring 42. Subsequently, the push plate 33 extrudes the engine hood blank from the lower mold 14. After extrusion, it is removed. Then, the electric telescopic stamping plate 13 can be restarted to extend and push the connecting rod 21 downward. After the connecting rod 21 moves downward, it pushes the transmission rod 22 and the pressure plate 23 downward. At this time, the sleeve 31, with the elastic potential energy of the first spring 32, pulls the push plate 33 downward back to its original position. Then, the pressure plate 23 moves downward and, under the positioning of the positioning cylinder 41, compresses the second spring 42. When the lower end of the electric telescopic stamping plate 13... After being inserted into the lower mold 14, the lower side of the electric telescopic stamping plate 13 has a certain gap with the lower side of the interior of the lower mold 14, serving as a storage space for the stamped engine hood cover blank. At this time, the blower 51 can be started to extract external air. The extracted air is discharged through the first connecting end 52 and injected into the lower mold 14 through the slot 15. Since the upper part of the lower mold 14 is blocked by the lower end of the electric telescopic stamping plate 13, the airflow will be discharged from the slot 15 at the other end of the lower mold 14. At this time, the vacuum pump 62 is started simultaneously. The vacuum pump 62 extracts the airflow flowing in the lower mold 14 through the second connecting end 61, so that the airflow carries the residual debris in the lower mold 14 and is extracted. The extracted airflow carrying the debris enters the collection box 71 through the conveying pipe 63 for storage, while the airflow is filtered through the filter screen 72 and discharged. The debris remains in the collection box 71. The cover plate 73 can be opened later to clean the debris stored in the collection box 71.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
