TECHNICAL FIELD
[0001] The utility model relates to the mould field, concretely relates to a mould for processing high-precision armature assembly. BACKGROUND
[0002] The armature assembly includes a framework, an armature, a coil and the like, and its processing requirement stipulates that the framework is of plastic material, and the plastic material is also used to wrap the armature and the coil. In the prior art, a twice injection molding process is used for production and processing, that is, the framework is first injection molded, then the coil is wound on the framework, and finally the framework and the armature with the wound coil are placed into a mold for twice injection molding, so as to finally form the armature assembly.
[0003] However, the processing difficulty of the armature assembly lies in that the product process requires that a groove is arranged on the long side of the armature assembly, and the bottom surface of the groove is the outer surface of the framework. In simple terms, the framework is once injection molded, for example, the once injection material is black; the armature assembly is twice injection molded, and the twice injection material is white, which wraps the framework and the armature. However, through the groove, it can be observed that the bottom surface of the groove is black. Since the size and depth of the groove are small (for example, the size of some grooves is 18mm*7mm*0.4mm), if the core for forming the groove on the mold is too large in force during the twice injection molding, the outer surface of the framework will be damaged (the temperature during the twice injection molding will also affect the strength of the framework), which will affect the structure of the entire product; if the core for forming the groove on the mold is too small in force, the groove will not be easily formed, and overflow or burr phenomenon will easily occur.

[0035] Example 1
[0036] This embodiment provides a mold for machining high-precision armature components, as shown in the attached figure. Figures 1-4 As shown, it includes:
[0037] The body 11 has a cavity 111, which is formed by the cooperation of a fixed mold 12 and a moving mold 13. In this embodiment, the cavity 111 is used for secondary molding of the armature assembly 14. The skeleton is processed in one molding process and is irrelevant to this embodiment, so the mold for one molding will not be described in detail. The long side of the armature assembly 14 has a groove 141. The number of grooves 141 is set according to product requirements, with one groove 141 corresponding to one movable insert 15. The depth of the groove 141 is 0.4mm. In this embodiment, both long side surfaces of the armature assembly 14 have grooves 141. During processing, the two long side surfaces of the armature assembly 14 correspond to the top and bottom surfaces of the inner wall of the cavity 111.
[0038] Movable insert 15, the movable insert 15 cooperates to form groove 141, the number of movable inserts 15 is set according to the number of grooves 141. The movable insert 15 extends into cavity 111, the part of the movable insert 15 extending into cavity 111 cooperates to form groove 141, which is the material removal structure known to those skilled in the art.
[0039] The first elastic member 16 is in abutment with the movable insert 15 at one end and in abutment with other components of the body 11 at the other end. During processing, the first elastic member 16 enables the movable insert 15 to be located at a preset position, and even if force is applied to the movable insert 15, the movable insert 15 can be reset to the preset initial position due to the buffering energy storage of the first elastic member 16, thereby ensuring that the position of the movable insert 15 does not move during processing. Through the arrangement of the first elastic member 16, a buffering effect is formed during mold clamping, thereby avoiding the movable insert 15 from being pushed through the framework due to excessive force, effectively avoiding the phenomena of material overflow and burrs, enabling the edge wall of the groove 141 to be smooth and burr-free, achieving the effect of high-precision processing, and improving product quality.
[0040] Specifically, as shown in the accompanying drawings, the body 11 includes a fixed plate 17, and the other end of the first elastic member 16 is in abutment with the fixed plate 17. Through the arrangement of the fixed plate 17, the elastic buffering effect of the first elastic member 16 is better achieved. In addition, the fixing can also be formed by other fixing methods. For example, the first elastic member 16 and the movable insert 15 are directly formed in an integrated structure and fixed inside the body 11. Figure 2
[0041] Specifically, the fixed plate 17 is provided with a fixed cavity 171, and the first elastic member 16 is accommodated in the fixed cavity 171. Here, one end of the first elastic member 16 is in abutment with the bottom surface of the fixed cavity 171, and the other end of the first elastic member 16 is in abutment with the movable insert 15. The arrangement of the fixed cavity 171 forms the fixing effect of the first elastic member 16, and the fixed cavity 171 also forms a guiding effect.
[0042] Specifically, the first elastic member 16 is a spring or an elastic rubber or a spring sheet or a plastic elastic member. Here, the first elastic member 16 can be adjusted according to actual needs.
[0043] Specifically, as shown in the accompanying drawings, the body 11 is provided with a glue port 112, a first channel 113, and a second channel 114. The first channel 113 and the second channel 114 are both in communication with the glue port 112. The other end of the first channel 113 is in communication with one side of the cavity 111, and the other end of the second channel 114 is in communication with the other side of the cavity 111. Through the glue feeding mode of the two channels, the glue feeding is more stable. When the body 11 is provided with only one cavity 111, one cavity 111 corresponds to two channels. When the number of cavities 111 is two, the number of channels is four. One glue port 112 can be matched with four channels, or two glue ports 112 can correspond to two channels respectively, thereby forming the effect of the glue entering the cavity 111. Based on this, a person skilled in the art can increase the number of corresponding cavities 111. Figure 3
[0044] Specifically, the body 11 comprises a fixed mold 12 and a movable mold 13, and the movable mold 13 is connected with a second elastic member 18.
[0045] Specifically, as shown in the accompanying drawings, Figures 1-2 the fixed mold 12 is provided with an inclined block 19, the inclined block 19 is provided with a first inclined surface 191, the movable mold 13 is provided with a fixed groove 131, the fixed groove 131 is provided with a second inclined surface 132, and the first inclined surface 191 is in contact with the second inclined surface 132 when the movable mold 13 cooperates with the fixed mold 12. The inclined block 19 cooperates with the fixed groove 131 to realize the fixing effect between the movable mold 13 and the fixed mold 12.
[0046] Specifically, as shown in the accompanying drawings, Figure 2 the body 11 further comprises a guide block 20 and a third elastic member 21, the guide block 20 is provided with a through hole 201, the inclined block 19 passes through the through hole 201 and cooperates with the fixed groove 131, one end of the third elastic member 21 is in contact with the guide block 20, and the other end of the third elastic member 21 is in contact with the outer wall of the cavity 111. The guide block 20 forms a guiding effect, and the third elastic member 21 forms a buffering and reverse force of the guide block 20, so as to better realize the cooperation between the guide block 20 and the inclined block 19. Here, the guide block 20 moves horizontally and transversely.
[0047] Specifically, as shown in the accompanying drawings, Figure 2 the through hole 201 is provided with a third inclined surface 202, and the inclined block 19 cooperates with the third inclined surface 202. When the first inclined surface 191 is in contact with the third inclined surface 202, the inclined block 19 drives the guide block 20 to move.
[0048] Specifically, in addition to the above, the body 11 is further provided with other inserts, and different inserts cooperate to form other structural features of the armature assembly 14.
[0049] Obviously, the above embodiments are only examples for clear illustration, and are not intended to limit the embodiments. Based on the above description, those skilled in the art can make other different forms of changes or modifications. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or modifications derived therefrom are still within the protection scope of the present application.
