[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the scope of the present invention.

[0028] Type restrictions.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0031] The present invention proposes an automatic stripping processing equipment for forming an automobile engine underbody, comprising a main housing 11, a fixing block 21 extending from the lower right end surface of the main housing 11, a fixing vertical plate 14 extending from the upper end surface of the fixing block 21, an upper fixing plate 13 extending from the upper left end surface of the main housing 11, a hydraulic cylinder 16 fixed to the middle lower end surface of the upper fixing plate 13, and a lower pressure plate 12 fixed to the lower end surface of the hydraulic cylinder 16;

[0032] The present invention starts the hydraulic cylinder 16 in the positive direction, which moves the lower pressure plate 12 downward, thereby driving the upper module 22 to move downward, and driving the upper module 22 to move into the lower die cavity 25 to perform die-casting on the automobile engine bottom guard plate.

[0033] After the bottom guard plate is formed, the hydraulic cylinder 16 is started in the reverse direction, driving the lower pressing plate 12 to move upward, and then driving the stripping plate 20 to move upward, so that the bottom guard plate is demoulded, which is convenient for later processing.

[0034] The upper end surface of the main box body 11 is provided with a plate placing cavity 36 with an upward opening and a U-shaped opening. The lower end surfaces on the left and right sides of the lower pressure plate 12 are extended with symmetrical drop boxes 37. The lower walls on the left and right sides of the plate placing cavity 36 are symmetrically provided with upper lifting cavities 26 with an upward opening and a U-shaped opening. The upper end surfaces on the left and right sides of the lower pressure plate 12 are provided with extension openings 18 with an upward opening and a U-shaped opening. A spring cavity 28 is provided in the side wall of the extension opening 18 away from the plate placing cavity 36.

[0035] Four positioning rods 15 are evenly distributed on the upper end surface of the main box body 11 and pass through the lower pressing plate 12.

[0036] A movable translation plate 34 is provided in the spring cavity 28, and a translation spring 33 is provided between a side of the translation plate 34 away from the plate placement cavity 36 and a side wall of the spring cavity 28 away from the plate placement cavity 36. A translation rod 35 is extended into the extension opening 18 on the side of the translation plate 34 close to the plate placement cavity 36.

[0037] A movable stripping plate 20 is provided in the plate placement cavity 36 . The upper end surface of the stripping plate 20 is provided with a lower limiting groove 24 with an upward opening and a U-shaped opening. A lower pressing groove 31 is penetrated through the lower wall of the lower limiting groove 24 .

[0038] The lower wall of the plate placement cavity 36 is provided with a lower mold cavity 25 with an upwardly opening and a U-shaped opening. The lower pressing groove 31 is connected to the lower mold cavity 25. The lower end surface of the lower pressing plate 12 is fixedly provided with an upper module 22. The upper module 22 has upper limit blocks 23 extending from both end surfaces. When the lower pressing plate 12 moves up and down, it is quickly positioned by the positioning rod 15, making the formed bottom guard plate more standardized. At the same time, when the lower pressing plate 12 moves downward, the upper limit block 23 moves into the lower limit groove 24, so that the bottom guard plate is formed on the stripping plate 20. In this way, when the stripping plate 20 moves upward, it will drive the bottom guard plate upward together, thereby achieving demolding.

[0039] A lower pressing hole 32 is provided between the upper and lower end surfaces on the left and right sides of the stripping plate 20, and a movable upper lifting baffle 27 is provided in the upper lifting cavity 26. The upper end surface of the upper lifting baffle 27 passes through the lower pressing hole 32 and extends into the extension opening 18 to form an extension rod 19, and a limiting plate 29 is fixed to the upper end surface of the extension rod 19.

[0040] The lower end surfaces of the left and right sides of the upper fixing plate 13 are extended with return rods 17, and the upper end surface of the limiting plate 29 is provided with an L-shaped return groove 30 that opens upward and away from the plate placement cavity 36.

[0041] The translation rod 35 has a first wedge-shaped surface, which can move the translation rod 35 and compress the translation spring 33 after contacting the limiting plate 29 .

[0042] The fall-back rod 17 has a second wedge-shaped surface, which, after contacting the translation rod 35 , causes the translation rod 35 to move and compress the translation spring 33 .

[0043] Under normal conditions, the extension rod 19 moves downward under the action of gravity, and when the lower pressure plate 12 moves downward, it drives the translation rod 35 to move downward, so that the translation rod 35 moves to the upper side of the limiting plate 29, and then is squeezed by the limiting plate 29, driving the translation rod 35 to compress the translation spring 33 until the translation rod 35 moves to the lower side of the limiting plate 29. At the same time, the translation plate 34 moves toward the direction close to the plate cavity 36 under the action of the translation spring 33, so as to drive the translation rod 35 to move toward the direction close to the plate cavity 36, thereby limiting the extension rod 19.

[0044] When the lower pressing plate 12 moves upward, it will drive the translation rod 35 to move upward, thereby driving the extension rod 19 to move upward, and the stripping plate 20 will also move upward to perform demoulding. When the lower pressing plate 12 moves upward to make the return rod 17 move into the return groove 30, the translation rod 35 is pushed by the return rod 17 to move away from the plate placement cavity 36, so that the extension rod 19 is freed from the restriction. In this way, the stripping plate 20 moves downward under the action of gravity and moves back into the plate placement cavity 36.

[0045] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
