Description

Technical Field

[0001] This utility model relates to the field of electric vehicle manufacturing technology, and in particular to a fixed mold for injection molded parts for electric vehicles. Background Technology

[0002] Electric tricycles are three-wheeled transportation vehicles powered by batteries and driven by motors, used for hauling goods or people. During the production process of electric vehicles, a plastic panel for the controller needs to be manufactured. The electric vehicle display plastic panel is a plastic component in front of the electric vehicle's display screen; it typically serves as a protective cover for the display screen, providing wind protection, safeguarding the screen, and also adding a decorative element. The electric vehicle display plastic panel is located in front of the electric vehicle's display screen and is the direct protective layer for the display.

[0003] like Figure 1 As shown, the controller's plastic panel is bent at one end at a right angle, and on the back of the right-angle bend, there is a row of clips that need to be injection molded for connection with parts on the electric vehicle. Currently, in existing molds, after the product is injection molded, demolding is performed. During the demolding process between the fixed mold and the moving mold, the clips are easily broken, causing the product to be scrapped.

[0004] Therefore, it is desirable to provide a mold for injection molded parts for electric vehicles, in order to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a fixed mold for injection molding parts for electric vehicles, which effectively protects the plastic buckles formed on the back of the product when demolding plastic panels bent at right angles, and greatly improves the product molding rate.

[0006] To achieve the above-mentioned utility model objectives, a fixed mold for injection molding parts for electric vehicles is provided, including a fixed mold base, a buffer plate, and a bending forming block;

[0007] The buffer plate is vertically slidably mounted on the fixed mold base by the limiting screw;

[0008] The buffer plate has a first contoured area;

[0009] The bending and forming block is slidably disposed on the upper surface of the buffer plate along the length direction of the buffer plate and is located on one side of the first contouring area;

[0010] A guide block is fixed on the fixed mold base, and the front and rear sides of the guide block are both parallel inclined surfaces.

[0011] The bending forming block is provided with an oblique hole, which penetrates the upper and lower surfaces of the bending forming block, and the bending forming block is slidably sleeved on the guide block through the oblique hole;

[0012] The buffer plate has several connection holes.

[0013] Preferably, the bending forming block includes a contour block and a mounting block. The contour block is adapted to the right-angle bending area of ​​the plastic panel. The contour block and the mounting block are detachably fixed. The oblique hole is provided on the mounting block.

[0014] Furthermore, hydraulic cylinders are symmetrically arranged on both sides of the fixed mold base, the piston rods of the hydraulic cylinders are arranged vertically upward, and the piston rods of the hydraulic cylinders are connected to the buffer plate.

[0015] Preferably, the mold base is provided with cooling water pipes.

[0016] The advantages of the fixed mold for injection molded parts for electric vehicles provided by this utility model compared with the prior art

[0017] (1) By setting a buffer plate on the fixed mold base and sliding a bending forming block on one side of the buffer plate; after the product is formed in the mold, the external hydraulic device drives the moving mold to move outward and separate from the fixed mold. At this time, the rubber plug on the moving mold core is in the connecting hole, pulling the buffer plate upward. Due to the effect of the limit screw, the buffer plate will not detach from the fixed mold base. Under the action of the guide block, the bending forming block moves upward and backward, separating from the right angle bending area of ​​the injection-molded plastic panel. The molded plastic panel is completely pulled out by the passive mold, effectively protecting the plastic buckle formed in the bending area of ​​the plastic panel.

[0018] (2) Simple structure and easy to use. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 2As shown, a fixed mold for injection molding parts for electric vehicles according to this utility model includes a fixed mold base 3, a buffer plate 4, and a bending forming block 5; the buffer plate 4 is vertically slidably disposed on the fixed mold base 3 by the limiting screw (not shown in the figure); the buffer plate 4 has a first contouring area 6; the bending forming block 5 is slidably disposed on the upper surface of the buffer plate 4 along the length direction of the buffer plate 4, and is located on one side of the first contouring area 6.

[0025] like Figure 2 and Figure 3 As shown, a guide block 7 is fixed on the fixed mold base 3, and the front and rear sides of the guide block 7 are mutually parallel inclined surfaces; the bending forming block 5 is provided with an inclined hole 8, which penetrates the upper and lower surfaces of the bending forming block 5, and the bending forming block 5 is slidably sleeved on the guide block 7 through the inclined hole 8.

[0026] The buffer plate 4 has several connection holes 9.

[0027] In this embodiment, as Figure 4 As shown, the bending forming block 5 includes a contour block 10 and a mounting block 11. The contour block 10 is adapted to the right-angle bending area of ​​the plastic panel. The contour block 10 and the mounting block 11 are detachably fixed. The oblique hole 8 is provided on the mounting block 11 to realize a detachable connection, which is convenient for subsequent maintenance.

[0028] In this embodiment, hydraulic cylinders 12 are symmetrically arranged on both sides of the fixed mold base 3. The piston rod of the hydraulic cylinder 12 is arranged vertically upward and is connected to the buffer plate 4. This arrangement facilitates the reset of the buffer plate 4.

[0029] In this embodiment, the fixed mold base 3 is provided with a cooling water pipe 13 to facilitate cooling of the mold and the molded product.
