Abstract
The utility model discloses the wear-resisting mold insert mechanism of a kind of shaped block, is provided with the die cavity matched with profile shapes in shaped block, extrudes direction and is provided with embedding piece groove, be inserted with the mold insert in convex-type chamber in described embedding piece groove in described die cavity along material.The utility model has the advantage of and can change upon wear, shaped block does not need again to make, and substantially prolongs shaped block service time, easy and simple to handle, is convenient to revise mould.
Description
Technical field
The utility model relates to plastic profile extrusion sizing field, particularly relates to a kind of wear-resistant detachable mold insert mechanism being applied to shaped block.
Background technology
When plastic profile extrusion is produced, the shaped block being arranged in cooling water tank mainly plays cooling and shaping effect.But when plastic profile extrusion is produced, owing to being subject to the resistance restriction of shaped block, during section bar extrusion, resistance becomes large, and section bar easily trembles, and the function bayonet socket causing shaped block serious wear, particularly partial aperture little is as adhesive tape mouth and press strip mouth position.Along with the impurity in the prolongation found time and cooling water tank is brought into, very easily cause Surface of profile to occur the defect such as bright band and cut, in high-speed production, especially seem more outstanding.
Utility model content
Technical problem to be solved in the utility model realizes a kind of insert structure improving shaped block anti-wear performance.
To achieve these goals, the technical solution adopted in the utility model is: the wear-resisting mold insert mechanism of a kind of shaped block, be provided with the die cavity matched with profile shapes in shaped block, extrude direction along material in described die cavity and be provided with embedding piece groove, in described embedding piece groove, be inserted with the mold insert in convex-type chamber.
Described embedding piece groove cross section is trapezium structure little outside the interior length of side, and described mold insert embeds embedding piece groove part and matches with it.
Described mold insert embeds embedding piece groove part and is provided with fluting.
Establish pin-and-hole in described fluting, in described pin-and-hole, be inserted with distribution.
The stainless steel material that described mold insert is more than HRC55 by quenching and tempering hardness is made.
The utility model has the advantage of and can change upon wear, shaped block does not need again to make, and substantially prolongs shaped block service time, easy and simple to handle, is convenient to revise mould.

Detailed description of the invention
As shown in Figure 1, the die cavity 2 matched with profile shapes is provided with in shaped block 1, for the little function bayonet socket of partial aperture as adhesive tape mouth and press strip mouth position, shaped by mold insert, thus change during convenient damage, needing the position of installing mold insert to arrange embedding piece groove 3, embedding piece groove 3 is extruded direction along material in die cavity 2 and is arranged, and is inserted with the mold insert in convex-type chamber 2 in embedding piece groove 3.
For convenience of fixing, and guarantee fixing reliable, as shown in Figure 2-5, embedding piece groove 3 cross section is trapezium structure little outside the interior length of side, mold insert embeds embedding piece groove 3 part and matches with it, this external mold insert embeds embedding piece groove 3 part and is provided with fluting, thus makes insertion portion have certain elasticity, establishes pin-and-hole in fluting, distribution 4 is inserted with in pin-and-hole, mold insert is fixed by distribution 4, ensure that mold insert can not rock in embedding piece groove 3, offsets.
Mold insert protrudes die cavity 2 partial shape and is limited by its functional characteristics, can adopt various shapes as required.For ensureing the stability that section bar is produced, this wear-resisting mold insert have employed the high-quality stainless steel material that quenching and tempering hardness is more than HRC55, greatly extends shaped block 1 service life, improves the surface quality of plastic shaped material products.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
