They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] As shown in Figures 1-8, an electric vehicle charger shell molding device includes a bottom mounting plate 1, a molding die 2 and a feeding device 6. The bottom mounting plate 1 is provided with a molding die 2 for molding, and the feeding device 6 replenishes the molding material into the molding die 2. It is characterized in that three molding dies 2 are evenly distributed in the circumference are provided on the bottom mounting plate 1, the bottom mounting plate 1 is arranged on a rotating device, the feeding device 6 is connected to the replenishing device, the molding die 2 is arranged on two positioning sliding devices 3, the sliding device 3 and the separating device 4 are arranged on the bottom mounting plate 1, the separating device 4 drives the molding die 2 to be demolded, and the feeding device 6 is provided with an exhaust device 5.

[0029] The molding material is injected into the molding die 2 through the feeding device 6. When the molding die 2 is filled with material, the exhaust device 5 will block the exhaust end of the molding die 2. After the molding die 2 is blocked, the feeding device 6 will automatically close and stop injecting material into the filled molding die 2. Then the bottom mounting plate 1 rotates to drive the molding die 2 without material to rotate above the feeding device 6. Then the feeding device 6 is released to add material to the new molding die 2. When the molding die 2 filled with material cools down, the separation device 4 allows the molding die 2 to slide on the sliding device 3 for demoulding.

[0030] As shown in Figure 1-8, the molding die 2 includes two outer molds 2-1, a semi-exhaust hole 2-2, a bottom plate 2-3, a feed hole 2-4, an inner mold 2-5 and a molding cavity 2-6. The outer mold 2-1 is arranged on a sliding device 3. The two outer molds 2-1 are enclosed into a cylinder. The outer mold 2-1 is provided with a semi-exhaust hole 2-2. The two semi-exhaust holes 2-2 enclose a circular hole. The bottom plate 2-3 is arranged on the bottom mounting plate 1. The bottom plate 2-3 is provided with an inner mold 2-5. A molding cavity 2-6 is provided between the two outer molds 2-1 and the inner mold 2-5. The bottom plate 2-3 is provided with a feed hole 2-4 connected to the molding cavity 2-6. The feeding device 6 is connected to the feed hole 2-4. The outer mold 2-1 is provided with an exhaust device 5 connected to the semi-exhaust hole 2-2. The separation device 4 drives the two outer molds 2-1 to move relative to each other.

[0031] The molding material is injected into the molding cavity 2-6 through the feed hole 2-4. As the material inside the molding cavity 2-6 gradually increases, the air inside the molding cavity 2-6 is discharged through the semi-exhaust hole 2-2. When the material enters the exhaust device 5 from the semi-exhaust hole 2-2, the molding cavity 2-6 is already filled with molding material. When demolding, pull the outer mold 2-1 toward both ends, and then remove the outer shell from the inner mold 2-5.

[0032] Among them, as shown in Figure 1-8, the inner mold 2-5 is hollow.

[0033] The inner molds 2-5 are hollow to reduce costs.

[0034] As shown in Figure 1-8, the sliding device 3 includes a first support rod 3-1, a fixed square tube 3-2 and a sliding square rod 3-3. The first support rod 3-1 is arranged on the bottom mounting plate 1, the fixed square tube 3-2 is arranged on the first support rod 3-1, the sliding square rod 3-3 slides on the fixed square tube 3-2, and the outer mold 2-1 is arranged on the sliding square rod 3-3.

[0035] The fixed square tube 3-2 and the sliding square rod 3-3 fix the sliding track of the outer mold 2-1.

[0036] As shown in Figure 1-8, the separation device 4 includes a second support rod 4-1, a servo motor 4-2, a gear 4-3, a first rack 4-4 and a second rack 4-5. The servo motor 4-2 is arranged on the bottom mounting plate 1 through the second support rod 4-1, the gear 4-3 is arranged on the servo motor 4-2, the first rack 4-4 is arranged on an outer mold 2-1, and the second rack 4-5 is arranged on another outer mold 2-1. The first rack 4-4 and the second rack 4-5 are both engaged with the gear 4-3.

[0037] The servo motor 4-2 drives the first rack 4-4 and the second rack 4-5 to move in opposite directions through the gear 4-3. The moving first rack 4-4 and the second rack 4-5 cause the two outer molds 2-1 to move to the sides or to the center.

[0038] As shown in Figure 1-8, the exhaust device 5 includes two half-tubes 5-1, a fixing frame 5-2, a sliding bolt 5-3, a float 5-4, a retaining ring 5-5 and an exhaust hole 5-6. A fixing frame 5-2 and a retaining ring 5-5 are provided inside one of the half-tubes 5-1. The sliding bolt 5-3 slides on the fixing frame 5-2. The float 5-4 is set on the sliding bolt 5-3. The retaining ring 5-5 is provided with an exhaust hole 5-6. The float 5-4 moves to the position of the retaining ring 5-5 to block the exhaust hole 5-6. The half-tube 5-1 is set on the outer mold 2-1 and is connected to the half exhaust hole 2-2.

[0039] After the material enters the two half-tubes 5-1, when the material is released to the float 5-4, the float will move upward. When the float 5-4 moves to the position of the retaining ring 5-5 and blocks the exhaust hole 5-6, the material can no longer be replenished into the molding cavity 2-6. When demolding, the half-tube 5-1 will move together with the outer mold 2-1.

[0040] As shown in Figure 1-8, the feeding device 6 includes a feeding pipe 6-1, a feeding hole 6-2, a connecting pipe 6-3, a sliding disk 6-4, a limiting ring 6-5, a connecting bent rod 6-6, a sliding baffle 6-7 and a discharge through-hole 6-8. The feeding pipe 6-1 is arranged on the feeding device, the feeding pipe 6-1 is connected to the feeding hole 2-4, the connecting pipe 6-3 is arranged on the feeding pipe 6-1 and is connected to the feed hole 6-2, the sliding disk 6-4 slides inside the connecting pipe 6-3, the sliding baffle 6-7 slides on the feeding pipe 6-1, the sliding baffle 6-7 is provided with a discharge through-hole 6-8 connected to the feed hole 6-2, the sliding disk 6-4 and the sliding baffle 6-7 are connected by a connecting bent rod 6-6, and a limiting ring 6-5 is provided on the connecting pipe 6-3.

[0041] When the molding cavity 2-6 is closed, the pressure inside the feeding pipe 6-1 will increase, and the increased pressure will push the sliding plate 6-4 to slide inside the connecting pipe 6-3. The moving sliding plate 6-4 drives the sliding baffle 6-7 to move through the connecting bent rod 6-6. The moving sliding baffle 6-7 separates the discharge hole 6-8 and the feed hole 6-2. The sliding baffle 6-7 blocks the feeding pipe 6-1 to prevent material waste.
