Description
[ technical field ] A method for producing a semiconductor device
The utility model belongs to the technical field of the mould design processing, especially, relate to an extrusion tooling panel that can effectively prevent excessive gluey.
[ background of the invention ]
In the prior art, the traditional extrusion panel is of an integrated structure, and the section of an extruded product is determined by a cavity of the panel. The extrusion process is widely applied to the production of the automobile sealing strip, and the automobile sealing strip generally comprises a built-in steel strip and a plastic coating part which is coated on the periphery of the built-in steel strip and has a set section shape. According to the structural design of a product, the phenomenon that the thickness of a local plastic cladding part is very thin exists, and in the production and processing process, the thickness of the part of the extruded plastic cladding part can be ensured to be within the design range due to the fact that the gap between the surface of the built-in steel belt and the surface of the panel cavity is required to be kept within the set range; however, the gap between the surface of the built-in steel strip and the surface of the panel cavity is very small, so that the shaking phenomenon can occur in the continuous pulling-out process of the built-in steel strip, the surface of the built-in steel strip is attached to the surface of the product cavity, the glue overflow phenomenon is caused when the built-in steel strip is attached to the wall of the cavity when the product is extruded out of the section, and the product quality and the appearance are seriously affected.
Therefore, there is a need to provide a new extrusion die panel that effectively prevents flash.
[ Utility model ] content
The utility model discloses a main aim at provides an extrusion tooling panel that can effectively prevent excessive gluey, can effectual solution die cavity inner wall and the incomplete glue problem in product built-in steel band clearance, avoid the sizing material to spill over from the panel and cause bad product, can effectively reduce the change rate of mould panel simultaneously.
The utility model discloses a following technical scheme realizes above-mentioned purpose: an extrusion die panel capable of effectively preventing glue overflow comprises a cavity which is profiled with the outline of a product, a built-in steel belt of the product passes through the cavity, and an elastic guide block which extends into the cavity and adjusts the gap between the built-in steel belt of the product and the inner wall of the cavity is arranged on the die panel.
Furthermore, a containing groove for limiting the movement elastic floating range of the elastic guide block is arranged on the die panel, and a part of the elastic guide block is arranged in the containing groove.
Furthermore, an elastic piece is arranged in the accommodating groove, one end of the elastic piece is fixed on the surface of the inner wall of the accommodating groove, and the other end of the elastic piece is fixedly connected with the elastic guide block.
Furthermore, one end of the elastic guide block abuts against the built-in steel belt of the product, and a slope guide surface is arranged on one surface facing the built-in steel belt of the product.
Compared with the prior art, the utility model relates to a can effectively prevent extrusion tooling panel of excessive glue's beneficial effect lies in: the spring guide block is additionally arranged to abut against the built-in steel belt of the product, so that the gap between the built-in steel belt of the product and the inner wall of the product cavity is maintained within a set range, and therefore the phenomenon that the rubber material overflows from a panel to cause bad products is avoided; the elastic guide block is embedded in the groove of the die panel through the elastic piece, so that on one hand, the space is saved, on the other hand, the elastic floating capacity of the elastic guide block is realized, the adjustment of the gap between the built-in steel belt of the product and the inner wall of the cavity of the product is facilitated, the elastic guide block is suitable for the production of products with different thicknesses, and the universality is high; the end part of the elastic guide block is provided with a slope guide surface, so that the steel belt can effectively and quickly pass through a product cavity, and the phenomenon of blockage, dragging and deformation is avoided; meanwhile, the elastic guide block is easier to replace after being worn, and the production cost is saved.

[ detailed description ] embodiments
Example (b):
referring to fig. 1 to 3, in the present embodiment, a face plate 100 of an extrusion die capable of effectively preventing glue overflow is provided, a product cavity 1 profiling an outer contour of a product, and an elastic guide block 2 having one end extending into the cavity 1 and adjusting a gap between an inner wall of the cavity 1 and a product built-in steel band 101.
The product built-in steel belt 101 passes through the product cavity 1.
The extrusion die panel 100 capable of effectively preventing glue overflow is provided with a receiving groove 4, and the elastic guide block 2 is disposed in the receiving groove 4 and limits the movement range thereof through the receiving groove 4.
An elastic piece 3 is further arranged in the accommodating groove 4, one end of the elastic piece 3 is fixed on the surface of the inner wall of the accommodating groove 4, the other end of the elastic piece is fixed on the elastic guide block 2, and the elastic floating of the elastic guide block 2 is realized through the elastic piece 3.
