Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a molding die for an electric vehicle shell. Background Technology

[0002] Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as their energy source and are powered by components such as controllers and motors. The outer shell of electric vehicles is mostly made of plastic parts and is processed into one piece using molding.

[0003] The existing announcement number CN219820535U, entitled "An Electric Vehicle Taillight Housing Mold," includes a mold base, an injection mold head, and a connecting seat. The injection mold head is movably embedded in the top surface of the mold base, and the connecting seat is integrally connected to the back of the mold base. An injection cavity is provided in the top opening of the mold base, and a lifting plate is movably embedded inside the injection cavity. An electro-hydraulic push rod is fixedly installed on the top surface of the connecting seat, and a movable top plate is connected to the top surface of the electro-hydraulic push rod. This utility model, by setting up an electro-hydraulic push rod and an injection mold head, allows the movable top plate to descend, which in turn causes a connecting rod to push the injection mold head down and embed it into the injection cavity. Then, hot-melt plastic is injected between the injection mold head and the injection cavity through the injection hole, forming the taillight housing using the injection mold head. Finally, the electro-hydraulic push rod is controlled to reset, causing the injection mold head to rise and disengage from the injection cavity. The structure is simple, the operation is convenient, and the use is easy, effectively improving work efficiency.

[0004] However, the above-mentioned molding dies are mostly processed by turning the whole blank into different outer shell cavities. Different electric vehicle shells require different mold cavities. The molding die cannot be quickly changed to a suitable cavity, and the cost of different mold cavities for different electric vehicle shells is high. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a molding die for electric vehicle shells.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an electric vehicle shell molding mold, including a mold frame, a lower mold core, a lifting frame, and a mold assembly component. Two limiting plates are symmetrically and horizontally fixed on the top of the mold frame, and multiple lower mold cores are horizontally assembled between the two limiting plates. A slide is horizontally arranged below the mold frame, and the slide is vertically slidably assembled on the mold frame. The lower mold cores are detachably assembled on the top surface of the slide. The lifting frame is vertically fixed on the top surface of the two limiting plates, and a mold assembly component is vertically slidably assembled on the lifting frame. The mold assembly component includes a hole frame, which is vertically slidably assembled on the lifting frame. Multiple upper mold cores are vertically inserted into the bottom surface of the hole frame, and the multiple upper mold cores correspond one-to-one with the multiple lower mold cores. A lower hydraulic rod is vertically fixed on the bottom surface of the mold frame, and the output end of the lower hydraulic rod is fixed on the bottom surface of the slide. An upper hydraulic rod is vertically fixed on the top surface of the lifting frame, and the output end of the upper hydraulic rod is fixed on the top surface of the hole frame.

[0007] As a preferred embodiment, multiple limiting strips are vertically fixed on both sides of the lower mold core, and a stud is vertically provided on the bottom surface of the lower mold core. A rotating seat is rotatably connected to the top of the stud, and the rotating seat is fixed on the bottom surface of the lower mold core.

[0008] As a preferred option, multiple sliding grooves are provided horizontally and vertically on the vertical end face of the limiting plate, and the multiple sliding grooves correspond one-to-one with the multiple limiting strips on the lower mold core for sliding assembly.

[0009] As a preferred option, multiple screw cylinders are vertically fixed on the carriage, and the screw cylinders are threadedly assembled and connected to the studs.

[0010] As a preferred embodiment, one end of the hole frame is fixed with a fixing seat, and the fixing seat is horizontally fixed with bolts.

[0011] As a preferred embodiment, a rod is horizontally mounted on the hole frame, and a through hole is horizontally opened at one end of the rod. The through hole on the rod is inserted into a bolt on the fixing seat, and a nut is threaded onto the bolt on the fixing seat.

[0012] As a preferred embodiment, a hole seat is fixed on the top surface of the upper mold core, and the hole seat on the upper mold core is slidably inserted into the rod frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, according to the processing requirements of electric vehicle shells, select appropriate lower mold cores of suitable shape and assemble them horizontally and sequentially on the top surface of the slide. Then, start the extension of the lower hydraulic rod to push the slide vertically upward on the mold frame, causing multiple lower mold cores to press against and assemble on the top of the limiting plate. Then, select appropriate upper mold cores of suitable shape according to the multiple lower mold cores and assemble them on the bottom surface of the hole frame. Then, in use, add molten plastic, start the extension of the upper hydraulic rod on the rod frame, push the upper mold core into the lower mold core, and complete the molding process of the plastic part. Thus, according to the actual processing requirements of electric vehicle shells, select appropriate lower mold cores of suitable shape for assembly. The mold only needs to replace the appropriate upper mold core and lower mold core, and there is no need to process the entire mold with different external structures. This reduces the cost of processing different mold cavities for different electric vehicle shells. Attached Figure Description

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

[0026] like Figures 1 to 5As shown, an electric vehicle shell molding die includes a mold frame 1, a lower mold core 2, a lifting frame 3, and a mold assembly 4. Two limiting plates 11 are symmetrically and horizontally fixed to the top of the mold frame 1, and multiple lower mold cores 2 are horizontally assembled between the two limiting plates 11. A slide 22 is horizontally arranged below the mold frame 1, and the slide 22 is vertically slidably assembled on the mold frame 1. The lower mold cores 2 are detachably assembled on the top surface of the slide 22. The lifting frame 3 is vertically fixed to the top surface of the two limiting plates 11. Above, a mold assembly 4 is vertically slidably assembled on the lifting frame 3. The mold assembly 4 includes a hole frame 41, which is vertically slidably assembled on the lifting frame 3. Multiple upper mold cores 42 are vertically inserted into the bottom surface of the hole frame 41, and the multiple upper mold cores 42 correspond one-to-one with multiple lower mold cores 2. A lower hydraulic rod 12 is vertically fixed on the bottom surface of the mold frame 1, and the output end of the lower hydraulic rod 12 is fixed on the bottom surface of the slide 22. An upper hydraulic rod 3 is vertically fixed on the top surface of the lifting frame 3. 1. The output end of the upper hydraulic rod 31 is fixed on the top surface of the hole frame 41. During use, according to the processing requirements of the electric vehicle shell, the lower mold core 2 of a suitable shape is selected and assembled horizontally on the top surface of the slide 22. Then, the lower hydraulic rod 12 is activated to extend, pushing the slide 22 to move vertically upward on the mold frame 1, causing multiple lower mold cores 2 to press against the top of the limit plate 11. Then, according to the multiple lower mold cores 2, the upper mold core 42 of a suitable shape is selected and assembled on the bottom surface of the hole frame 41. Then, molten plastic is added, the upper hydraulic rod 31 on the rod frame 3 is activated to extend, pushing the upper mold core 42 to insert into the lower mold core 2, completing the molding process of the plastic part. Thus, according to the actual processing requirements of the electric vehicle shell, the lower mold core 2 of a suitable shape is selected for assembly. The mold only needs to replace the appropriate upper mold core 42 and lower mold core 2, without the need to process the entire mold with different external structures, reducing the cost of processing different mold cavities for different electric vehicle shells.

[0027] In one embodiment, such as Figure 3 and 4 As shown, multiple limiting strips 21 are vertically fixed on both sides of the lower mold core 2, and studs 24 are vertically arranged on the bottom surface of the lower mold core 2. The top of the studs 24 is rotatably connected to a rotating seat 25, and the rotating seat 25 is fixed on the bottom surface of the lower mold core 2. Multiple sliding grooves 111 are horizontally and vertically opened on the vertical end face of the limiting plate 11, and the multiple sliding grooves 111 correspond one-to-one with the multiple limiting strips 21 on the lower mold core 2 and are slidably assembled. Multiple screws are vertically fixed through the slide 22. The cylinder 23 and the screw cylinder 23 are threadedly connected to the stud 24. During use, different lower mold cores 2 are arranged horizontally and sequentially above the slide 22. Then, the stud 24 on the bottom surface of the lower mold core 2 is rotated and threadedly assembled into the screw cylinder 23 of the slide 22, which facilitates the vertical installation of multiple lower mold cores 2 arranged horizontally and sequentially above the slide 22. The limiting strip 21 on the lower mold core 2 and the sliding groove 111 on the limiting plate 11 are slidably assembled, which improves the assembly effectiveness of the lower mold core 2 and the limiting plate 11.

[0028] In one embodiment, such as Figure 2 and 5 As shown, a fixing seat 43 is fixed to one end of the hole frame 41, and a bolt is horizontally fixed on the fixing seat 43.

The through hole on the rod frame 45 is inserted into the bolt on the fixing seat 43, and a nut 44 is threaded onto the bolt on the fixing seat 43. A hole seat 421 is fixed on the top surface of the upper mold core 42, and the hole seat 421 on the upper mold core 42 is slidably inserted into the rod frame 45. In use, the rod frame 45 slides through the hole seat 421 on the top surface of the upper mold core 42, and then the rod frame 45 is inserted into the bolt on the fixing seat 43. The nut 44 is threaded onto the bolt on the fixing seat 43 to ensure the stability of locking the upper mold core 42.

[0029] In this embodiment, according to the processing requirements of the electric vehicle shell, lower mold cores 2 of appropriate shape are selected and horizontally assembled on the top surface of the slide 22. Different lower mold cores 2 are horizontally arranged on the slide 22. Then, the studs 24 on the bottom surface of the lower mold cores 2 are screwed into the screw cylinder 23 of the slide 22, which facilitates the vertical installation of multiple lower mold cores 2 horizontally arranged on the slide 22. The limiting strips 21 on the lower mold cores 2 are slidably assembled with the sliding grooves 111 on the limiting plate 11. Then, the lower hydraulic rod 12 is activated to extend, pushing the slide 22 to move vertically upward on the mold frame 1, causing multiple lower mold cores 2 to press against the top of the limiting plate 11. Then, according to the multiple lower mold cores 2, an upper mold core 42 of appropriate shape is selected and assembled on the bottom surface of the hole frame 41. Then, molten plastic is added, and the upper hydraulic rod 31 on the rod frame 3 is activated to extend, pushing the upper mold core 42 to insert into the lower mold core 2, completing the molding process of the plastic part. Thus, according to the actual processing requirements of the electric vehicle shell, a lower mold core 2 of appropriate shape is selected for assembly.
