Description

Technical Field

[0001] The utility model belongs to the technical field of mold tooling, and relates to a special-shaped plastic sealing mold applied to a special-shaped servo controller. Background Art

[0002] The special-shaped servo controller is a key component of the servo system. This type of servo controller utilizes a metal housing as its structural load-bearing member. Its circuit components are secured by four printed circuit boards connected to a vertical plate via inter-board electrical supports. However, overall specifications require it to meet the requirements for use in environments with a launch overload (≥12,000g). Currently, structural designs typically utilize the foaming properties of liquid, high-strength plastic encapsulant to encapsulate the circuitry within the electronic components. By controlling the density of the liquid foam, the circuit components' overload resistance is enhanced.

[0003] The servo controller to be encapsulated is a quarter-circle structure with electrical test ports reserved on the side, independent electrical guide pins at the bottom, and a standard electrical connector at the top. During encapsulation, the electrical test ports, guide pins, and connector must remain intact and protected from the plastic compound and the pressure generated by the liquid plastic compound during expansion. The reliability of the electrical signal connection must be guaranteed.

[0004] The existing plastic packaging mold currently used has poor sealing performance and is inconvenient to operate in clamping and positioning, resulting in a low yield rate of the finished product of the steering gear servo controller after plastic packaging, and cannot meet the existing indicator requirements of the steering gear servo controller.

[0005] In order to meet the technical requirements and reserve the electrical interface intact, this solution designs a special-shaped plastic packaging mold for the servo controller. Utility Model Content

[0026] Reference Figures 1 to 3 As shown, the special-shaped plastic encapsulation mold for the servo special-shaped controller in this embodiment includes an upper clamping block 1, an insert 2, an arc plate 3, a side plate I4, a side plate II5, a lower clamping block 6, and a cover plate 7; the upper clamping block 1 and the lower clamping block 6 are arranged up and down, and the side surfaces are surrounded by the arc plate 3, the side plate I4, and the side plate II5 to form a cylindrical inner cavity; the special-shaped controller to be plastic-encapsulated is arranged on the lower clamping plate 6, the insert 2 is placed on the top, and the cover plates 7 are placed around it for fixation.

[0027] The upper clamping block 1 and the lower clamping block 6 are of the same sector shape.

[0028] The special-shaped controller to be plastic-sealed is arranged vertically between the lower clamping block 6 .

[0029] Two groups of positioning holes are provided on the lower clamping block 6. Each group of positioning holes is arranged to form an arc. The two arcs formed by the two groups of positioning holes are concentric arcs. The guide pins of the special-shaped controller to be plastic-sealed pass through the two groups of positioning holes.

[0030] The curvature of the arc plate 3 is consistent with the curvature of the upper clamping block 1 and the lower clamping block 6. The arc plate 3 is supported between the corresponding arc edges of the upper clamping block 1 and the lower clamping block 6. The side plate I4 and the side plate II5 are respectively supported between the two sets of radius edges corresponding to the upper clamping block 1 and the lower clamping block 6.

[0031] The upper clamping block 1 and the lower clamping block 6 are respectively provided with center positioning holes on their arc sides and two sets of radius sides, and are positioned and connected to the arc plate 3, side plate I4 and side plate II5 through the center positioning holes.

[0032] The centers of the upper and lower end surfaces of the arc plate 3 , the side plate I 4 , and the side plate II 5 are all provided with threaded holes, which are aligned with the central positioning hole and are connected using bolts 8 .

[0033] One end face of the arc plate 3 is connected to one inner wall face of the side plate I4, the other inner wall face of the arc plate 3 is connected to one end face of the side plate II5, and the other end face of the side plate I4 is connected to the other inner wall face of the side plate II5.

[0034] Three connection holes are provided on the butt-jointed contact surfaces between the arc plate 3, the side plate I4 and the side plate II5, and the connection holes are connected by bolts.

[0035] The bolts used for connecting the upper clamping block 1, the lower clamping block 6, the arc plate 3, the side plate I 4, and the side plate II 5 are all hexagonal head bolts.

[0036] The working principle of this utility model is as follows:

[0037] The guide pins extending from the circuit connector on the special-shaped controller to be plastic-sealed are passed through the 15 positioning holes provided on the lower clamping plate 6 , and the special-shaped controller to be plastic-sealed is placed vertically to the lower clamping plate 6 .

[0038] The center positioning hole of the arc plate 3 and the center positioning hole of the lower clamping block 6 are fixedly connected with bolts 8, and then the side panels I4 and II5 are respectively placed on both sides of the arc plate and fixed with bolts 8. Three bolts 8 are used for fixing at each position. After the connection is completed, a semi-enclosed cavity is completed.

[0039] Next, insert 2 is placed on the irregularly shaped controller to be encapsulated. Cover plate 7 is placed within the cavity formed by arc plate 3, side plate I 4, side plate II 5, and lower clamping block 6 to secure the encapsulated controller under test. Once this is in place, liquid encapsulation compound can be introduced. The quality of the liquid encapsulation compound must meet the design specifications.
