Profiling silicone rubber mold of lawn mower part and preparation method thereof

Abstract

The invention discloses a profiling silicone rubber mold of a lawn mower part and a preparation method thereof, and belongs to the technical field of a lawn mower assembly line technique. The profiling silicone rubber mold of the lawn mower part comprises a profiling positioner and a quick changing device, wherein the profiling positioner comprises a mold outer box, a clamp arranged on one cornerof the mold outer box, and a positioning plate arranged on the other corner of the mold outer box; the quick changing device comprises a fixed seat, a center shaft arranged in the middle of the fixedseat, and a stand column arranged under the fixed seat; the lawn mower part is arranged between the profiling positioner and the quick changing device and is fixed on the lower side of the fixed seat;the lawn mower part is suspended in an inner cavity of the mold outer box; and a silica gel is fully filled in the gap between the lawn mower part and the mold outer box. The profiling silicone rubber mold of the lawn mower part provided by the invention is simple in structure, convenient to clamp, low in assembling difficulty, and less in positioning error due to the tight contact of a positioning plane and a profiling surface, and ensures the assembling accuracy; the flexible silica gel contacts the curve surface of the lawn mower part, so that the surface wear and the collision of the lawnmower part are not easily caused, and the price is low.

Description

technical field [0001] The invention relates to a silicone mold, in particular to a profiling silicone mold for lawnmower components and a preparation method thereof, belonging to the technical field of lawnmower assembly lines. Background technique [0002] Traditional lawnmower components have complex structure, inconvenient clamping, low positioning accuracy, high price and short service life. [0003] Current lawn mowers use multiple positioning planes in contact with the curved shell for positioning, which has the following disadvantages: [0004] 1. The positioning error generated by the contact between the positioning plane and the surface of the shell will be transmitted to the specified feature structure of the assembly. Due to multiple errors, it will affect the assembly accuracy of the components. [0005] 2. In order to maintain the stability of the assembly parts, it is necessary to add multiple positioning planes, which will also cause the parts to be over-pos...

AI Technical Summary

Problems solved by technology

[0004] 1. The positioning error generated by the contact between the positioning plane and the surface of the shell will be transmitted to the specified feature structure of the assembly. Due to multiple errors, it will affect the assembly accuracy of the components

[0005] 2. In order to maintain the stability of the assembly parts, it is necessary to add multiple positioning planes, which will also cause the parts to be over-positioned. In order to avoid this situation, some positioning planes need to be made of soft materials, but this will increase the difficulty of assembly

[0006] 3. The hard positioning material contacts the assembly parts, and there is a possibility of abrasion and bumping the surface of the parts

[0007] Traditional lawnmower component tooling in related fields of lawnmower assembly line, especially a component positioning mechanism with complex curved surface, complex structure, inconvenient clamping and low assembly accuracy
