Embodiment Construction

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0024] see figure 1 and figure 2 , the filter screen mold according to the present invention comprises a fixed mold 10 and a movable mold 20; the mesh material is arranged between the fixed mold 10 and the movable mold 20; a plurality of pins 30 are arranged on the fixed mold 10, and the pins 30 are arranged on the mesh Both sides of the material and stop the edge of the material.

[0025] see figure 1 and figure 2 , The filter screen mold also includes hanging pins 40, and the hanging pins 40 are arranged on the movable mold 20 and pass through the edge of the mesh material. The hanging pins 40 are arranged outside the grid area of ​​the net material. To locate the non-grid part of the edge of the net material, the fixed mold 10 is provided ...

Abstract

The invention provides a filter screen mold. The filter screen mold comprises a fixed mold, a movable mold, a net material which is arranged between the fixed mold and the movable mold, and multiple pins which are arranged on the fixed mold, located at two sides of the net material and used for blocking the edge of the net material. The pins are arranged on the fixed mold and the net material is clamped by the pins so that the net material tightly clings to the fixed mold and thus in net material molding, the technical problem of part disqualification caused by cavity deviation is solved, production efficiency is improved and a production cost is reduced.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a filter mesh mould. Background technique [0002] When the filter net mold is produced, it is necessary to manually put the net material in the mold cavity before injection molding, and then close the mold and inject it into one. Due to the curved surface of the filter screen product, the mesh material is not easy to locate, and the unreasonable method of hanging the mesh may easily cause the mesh material to deviate from the cavity during molding, resulting in unqualified parts. The mesh is positioned with 2 hanging needles. Because the net material is dense and hard, the hanging needles for positioning the net material are relatively sharp. If the operator hangs the net to the fixed mold too fast, it will easily prick his hands, posing a safety hazard; if it is too slow, the production efficiency will be low and the production cost will increase. The hanging pins for positioning the me...
