AI Technical Summary
The filter screen of the existing power tool air vent cover is difficult to position in the mold, especially the edge of the filter screen is difficult to keep accurately positioned during the plastic wrapping process.
The filter screen is held in place by a front and rear mold core structure and several retractable positioning blocks. The positioning blocks are automatically hidden when the mold is closed to avoid opening positioning points on the filter screen. The filter screen is stably held and positioned by the elastic force of the front and rear mold springs.
It enables quick and convenient positioning of filter screens, is suitable for filter screens of different thicknesses, avoids positioning deviation, and optimizes the processing flow.

Abstract
Claims
1. A machining die for an electric power tool air outlet guard, characterized by: The mold includes a front mold core (1) and a rear mold core (2). Several positioning blocks (3) are vertically slidably arranged on the top of the rear mold core (2). A rear mold spring (4) is arranged between the positioning blocks (3) and the rear mold core (2). The filter screen (5) to be processed is placed on the top of the rear mold core (2), and all the positioning blocks (3) clamp the filter screen (5) to be processed from the side. A front mold spring block (6) is vertically slidably arranged on the bottom of the front mold core (1). A front mold spring block (7) is arranged between the front mold spring block (6) and the front mold core (1). When the bottom of the front mold core (1) abuts against the top of the rear mold core (2) and closes the mold, the front mold spring block (6) presses against the filter screen (5) under the elastic force of the front mold spring block (7). The front mold core (1) presses the positioning block (3) to overcome the elastic force of the rear mold spring block (4) and moves downward away from the filter screen (5).
2. The machining die for the protective cover of the air outlet of the electric power tool according to claim 1, characterized in that: The rear mold core (2) has an injection groove (201) on its top. The injection groove (201) is located below the outer edge of the filter screen (5) to be processed. The positioning block (3) has a docking groove (301) on its top side that contacts the filter screen (5) to be processed. When the front mold core (1) and the rear mold core (2) are closed, the docking groove (301) on the positioning block (3) moves downward and is flush with the injection groove (201).
3. The machining die for a protective cover of an air outlet of a power tool according to claim 1, characterized in that: The rear mold core (2) has a vertically opened rear mold groove at the top, and the positioning block (3) is vertically slidably disposed in the rear mold groove.
4. The machining die for a protective shroud for an air outlet of a power tool of claim 3, wherein: The bottom side of the positioning block (3) is provided with a rear mold limiting protrusion (302).
5. The machining die for a protective shroud for an air outlet of a power tool of claim 1, wherein: The bottom of the front mold core (1) is vertically provided with a front mold groove, and the front mold spring block (6) is vertically slidably disposed in the front mold groove.
6. A machining die for a protective shroud for an air outlet of a power tool according to claim 5, characterized in that: The front mold spring block (6) is provided with a front mold limiting protrusion (601) on the top side.
7. The machining die for a protective shroud for an air outlet of a power tool of claim 1, wherein: The positioning block (3) is set in three parts.
