[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1-7 As shown, the utility model is to solve the problem that the existing rolled plate type commutator insert splitting hook mold adopts a one-way splitting hook design, and each insert needs to go through two stamping processes to form a dovetail structure in the upper and lower directions respectively. This processing method is inefficient and increases the production cycle and cost. The following technical solutions are provided: a two-way splitting hook mold for a rolled plate type commutator insert, comprising an upper mold base 1, an upper clamping plate 2, a lower mold base 3 and a lower clamping plate 4, an upper pad 5 is arranged on the lower side of the upper clamping plate 2, an upper fixing plate 6 is arranged on the lower side of the upper clamping plate 5, an upper fixing sleeve 7 is vertically arranged in the upper fixing plate 6, the upper fixing sleeve 7 is connected to the upper pad 5, and the upper fixing sleeve 7 is connected to the upper pad 5. An upper die inner stripper 8 is inserted in the fixed sleeve 7, and an upper die chopping knife 9 is slidably provided in the middle of the upper die inner stripper 8, and the upper die chopping knife 9 passes through the upper clamping plate 2 and is connected to the upper die seat 1; a lower pad 10 is provided on the upper side of the lower clamping plate 4, and a lower fixed plate 11 is provided on the upper side of the lower pad 10, and a lower fixed sleeve 12 is vertically provided in the upper fixed plate 6 just below the upper fixed sleeve 7, and a lower die outer stripper 13 is inserted in the middle of the lower fixed sleeve 12, and a lower die chopping knife 14 is slidably provided in the middle of the lower die outer stripper 13, and the lower die chopping knife 14 passes through the lower clamping plate 4 and is connected to the lower die seat 3, and the dovetails of the insert in two directions are processed at the same time, with high efficiency.

[0024] In this embodiment, if Figure 1 As shown, the lower part of the upper die blade 9 and the upper part of the lower die blade 14 are both provided with a concave forming groove 91 , through which the upper and lower dovetails of the insert are punched and formed simultaneously.

[0025] In this embodiment, if Figure 1 As shown, the cross section of the molding groove 91 gradually increases from the middle section to the end portion, and the dovetail curvature of the insert is controlled by the inclined molding groove 91 surface.

[0026] In this embodiment, if Figure 5 As shown, a plurality of positioning protrusions 131 inserted into the insert grooves are arranged at intervals along the circumferential direction on the upper portion of the lower mold release 13 to position the insert.

[0027] In this embodiment, if Figure 4 As shown, a first slide groove 81 matching the upper die chopping knife 9 is provided through the middle of the upper die inner stripper 8, and the structure is simple. The first slide groove 81 allows the upper die chopping knife 9 to slide smoothly during the chopping hook process.

[0028] In this embodiment, if Figure 5 As shown, a second slide groove 132 matching the lower die chopping knife 14 is provided through the middle of the lower die release 13, and the structure is simple. The second slide groove 132 allows the lower die chopping knife 14 to slide smoothly during the chopping hook process.

[0029] In this embodiment, if Figure 3 As shown, an avoidance groove 71 is provided at the bottom of the upper fixing sleeve 7 to provide an avoidance space during the hook splitting process.

[0030] In this embodiment, if Figure 1 As shown, first, place the rolled plate type commutator insert to be processed on the upper side of the lower die outer stripping 13, insert the positioning protrusions 131 into the bottom groove of the insert respectively, ensure the correct position of the insert in the mold, the molding groove 91 on the upper part of the lower die splitter 14 is against the bottom of the insert, press the start button, and the upper die seat 1 moves down, so that the upper die splitter 9 and the lower die splitter 14 simultaneously split and hook the insert. Since the upper die splitter 9 and the lower die splitter 14 are both provided with a concave molding groove 91, the required dovetail structure can be formed on the insert during the splitting and hooking process, and the cross-section of the molding groove gradually increases from the middle section to the end, which helps to provide a better molding effect. After the stamping is completed, the upper die seat 1 is reset, and then the insert is ejected through the upper die inner stripping 8 to complete the demolding.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
