detailed description

The utility model is further described in conjunction with the following examples.

A specific embodiment of a mold for producing resistor brackets of the present utility model, as shown in Figures 2 to 4, includes an upper mold 22 and a lower mold 33, and a mold for forming is provided between the upper mold 22 and the lower mold 33. The cavity of the product, specifically, the upper mold 22 includes a mold handle 2, an upper mold base 3, an upper splint 4, a stripping back plate 5 and a stripper plate 6 arranged sequentially from top to bottom, the mold handle 2, the upper mold base 3 It is fixedly connected with the upper clamping plate 4, and the stripping back plate 5 is fixedly connected with the stripping plate 6. There is a gap between the upper clamping plate 4 and the stripping back plate 5 and an elastic reset mechanism is arranged.
