Embodiment approach

[0090] According to an embodiment of the dynamic model of the present invention, such as Figure 10-12 As shown, the movable mold 4 includes two opposite core-pulling sliders 5, and both core-pulling sliders 5 have a stepped structure that cooperates with each other for mutual insertion. The two core-pulling sliders 5 are used for forming and assembling The lower part 133 of the assembly and the connecting part 134 of the assembly, that is, the two core-pulling sliders 5 are combined to form a cavity surface for injection molding the lower part 133 of the assembly and the connecting part 134 of the assembly.

[0091] It should be noted that the lower part 133 of the assembly generally needs to form a positioning structure, and the plug-in end of the connector 15 needs to form a port structure, and the above structures are formed by two opposing core-pulling sliders 5 .

[0092] The positioning structure of the lower part of the assembly of the present invention includes but is...

Abstract

The invention belongs to the technical field of rotary transformers, and in particular relates to a rotary transformer integrated molding process and its injection mold. The invention integrates the stator frame assembly and the housing of the rotary transformer through injection molding of high-strength engineering plastics. The device is directly formed on the resolver body, reducing the number and steps of assembly parts of the whole machine, reducing the accumulation of installation dimension tolerances, improving the accuracy of system products, and strengthening the overall strength of the resolver; on the other hand, reducing the number of resolver assembly parts and steps, The product structure is more compact, the process is simpler, and the cost is lower; in addition, the present invention divides the shell into a cover plate and an assembly body, and then molds it integrally through the rotary transformer injection mold, thus solving the difficulty of demoulding.

Description

technical field [0001] The invention belongs to the technical field of rotary transformers, and in particular relates to a rotary transformer integral molding process and an injection mold thereof. Background technique [0002] Resolvers have been widely used in various industries, especially in the field of new energy vehicles. Resolvers have strong anti-interference ability, long service life and strong adaptability to harsh environments, so they have basically replaced other types of sensors in motor systems. inside. [0003] The installation position of the resolver in the motor system is generally at the head and tail ends of the motor shaft, and then a protective structure is added. [0004] Such as figure 1 As shown, the rotary transformer 1' in the prior art includes a stator frame assembly 11' and a rotor 12', the rotor 12' is installed on the motor shaft 2', the stator frame assembly 11' is fixedly installed in the casing 13', and the casing 13' is fixedly conne...
