[0002] An on-board charger is an electronic device used to charge the high-voltage battery packs of pure electric vehicles or plug-in hybrid electric vehicles. It converts alternating current (AC) from the power grid into direct current (DC) suitable for the vehicle's battery pack. Bidirectional on-board chargers can also allow the vehicle to power appliances in a car refrigerator. Due to space constraints, the on-board charger's housing needs to protect internal components while also saving installation space. As shown in the attached diagram, one type of on-board charger housing has an arc-shaped top, a sloping inner front side with an inward buckle, and a near 90° arc-shaped notch at the rear to avoid pipelines. During demolding, the mold core is restricted by the inward buckle, the arc-shaped notch, and the gap between the top surface, making demolding difficult. Utility Model Content

[0031] The principle of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0032] This utility model proposes a slanted top release mold, and the product 300 produced by injection molding is the on-board charger housing in the background art. The inclined ejector mold includes a front mold 100, a rear mold 200, and a cavity formed when the front mold 100 and the rear mold 200 are closed. The inner side of the cavity is composed of a mold core 1 located in the rear mold 200, a shovel-shaped plate 2 located in front of the mold core 1, and a slope plate 3 located behind the mold core 1. The shovel-shaped plate 2 is connected to a pair of first inclined ejector mechanisms 4, and the slope plate 3 is connected to a pair of second inclined ejector mechanisms 5. The shovel-shaped plate 2 is used for forming the arc edge of the front part of the product 300. The first inclined ejector mechanism 4 is used to push the shovel-shaped plate 2 obliquely to separate it from the product 300 after the mold core 1 is separated from the product 300. The slope plate 3 is used for forming the slope surface and the slope inner buckle 310 of the product 300. The second inclined ejector mechanism 5 is used to push the slope plate 3 obliquely to separate it from the product 300 after the mold core 1 is separated from the product 300.

[0033] The inner wall of the cavity of the inclined ejector mold is composed of a shovel-shaped plate 2, a slope plate 3, and a mold core 1. During demolding, the mold core 1 is first retracted to make room. Then, the first inclined ejector mechanism 4 and the second inclined ejector mechanism 5 are used to push the shovel-shaped plate 2 and the slope plate 3 obliquely towards the mold core 1 to disengage from the gap 320 and the inner clip 310, thereby achieving smooth demolding.

[0034] In this embodiment, the rear mold 200 is provided with a push plate 6 that reciprocates along the mold opening direction. The rear mold 200 also includes a rectangular frame structure composed of a rear template 210, a rear mold fixing plate 220, and a pair of side plates 230. The push plate 6 is parallel to the rear template 210 and the rear mold fixing plate 220 and is slidably disposed between the pair of side plates 230. A first hydraulic cylinder 61 is fixedly mounted at one end of the rear template 210, and a second hydraulic cylinder 62 is fixedly mounted at the opposite end. The piston rod of the first hydraulic cylinder 61 is connected to one end of the push plate 6, and the piston rod of the second hydraulic cylinder 62 is connected to the other end of the push plate 6. The push plate 6 is driven by the first hydraulic cylinder 61 and the second hydraulic cylinder 62. The mold core 1 is fixedly mounted at the front of the rear template 210. The first inclined release mechanism 4 includes a slide 41, a trolley 42, and a first connecting rod 43. The slide 41 has an inclined slide groove 44 with an opening at the top and a through groove 45 at the bottom. The trolley 42 is slidably disposed in the inclined slide groove 44 and has a first guide hole 46. The bottom of the first connecting rod 43 passes through the first guide hole 46, and the top of the first connecting rod 43 is fixedly connected to the shovel-shaped plate 2. The slide 41 is fixedly mounted on the push plate 6, and the side plate 230 has a guide groove 47. The first connecting rod 43 extends laterally from the guide rod 48 and inserts into the guide groove 47. When the push plate 6 moves forward, the slide 41 pushes the trolley 42 to slide obliquely, and the first connecting rod 43 drives the shovel-shaped plate 2 to move towards the mold core 1, causing the shovel-shaped plate 2 to disengage from the clamping gap 320.

[0035] In this embodiment, the second inclined release mechanism 5 includes a slide rail 51, a slider 52, and a second connecting rod 53. The slide rail 51 is provided with a horizontal groove 54, and the slider 52 is slidably disposed in the horizontal groove 54. The slider 52 is provided with a second guide hole 55 extending obliquely. The bottom of the second connecting rod 53 passes through the second guide hole 55, and the top of the second connecting rod 53 is fixedly connected to the slope plate 3. The second connecting rod 53 has an inclination angle with the push plate 6. When the push plate 6 pushes backward onto the template, it forces the second connecting rod 53 to translate towards the mold core 1, so that the slope plate 3 is released from the limiting range of the inner buckle 310. The top of the mold core 1 is provided with an inner buckle molding block 11 for forming the inner buckle 310. The inner buckle molding block 11 is released from the product along with the mold core 1.

[0036] When demolding, the push plate 6 simultaneously pushes the first inclined ejector mechanism 4 and the second inclined ejector mechanism 5, so that the shovel-shaped plate 2 and the slope plate 3 do not detach from the product 300 synchronously with the mold core 1, and move closer to the mold core 1 after the mold core 1 makes room, so as to disengage from the gap 320 and the inner buckle 310.

[0037] In this embodiment, a heating pipe 31 is provided inside the slope plate 3, which can keep the adhesive fluid during the injection process to avoid premature curing of the adhesive during injection and thus affecting product quality.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
