Profile forming mold of single-layer door frame

Abstract

The invention relates to a profile forming mold of a single-layer door frame. The profile forming mold is sequentially connected with an opening mold a, an opening mold b, an opening mold c, a convergence plate, a support plate a, a support plate b, a transition plate, a mold body and a core rod from front to back. The core rod is composed of a large core rod and a small core rod. The tail of thelarge core rod is embedded into the support plate a and the support plate b at the same time, the front end of the large core rod is flushed with the outer end face of the opening mold a, and the front end face of the large core rod is segmented into five independent large core rod bodies a, b, c, d and e backwards by 45 mm. The small core rod comprises a small core rod body A and a small core rodbody B. The upper end of the small core rod body A is embedded to the left lower corner of the large core rod body c, and the lower end of the small core rod body B is embedded to the right upper corner of the large core rod body b. The area defined by the large core rod body b, the large core rod body d, the large core rod body e, the opening mold a and the opening mold b is used for forming a door plate mounting cavity on a profile of the single-layer door frame. The profile forming mold is simple and practical in structure improvement and good in profile forming effect and has good actualuse and popularization value.

Description

technical field [0001] The invention relates to the technical field of extrusion profile forming dies, in particular to a single-layer door frame profile forming die. Background technique [0002] Wood-plastic doors and windows are a new type of material in interior decoration at present. Different from traditional granite, marble and PU materials, wood-plastic is a kind of fusion extrusion molding of pvc resin, high-quality stone powder and some auxiliary materials at high temperature. The new composite decorative material not only has the characteristics of stone powder being insoluble in water and not afraid of fire, but also has the characteristics of flexibility, wear resistance and bending resistance of PVC material. [0003] The traditional single-layer door frame is either directly made of solid material or made of extruded profiles. However, if the extruded profiles are processed and manufactured, due to the large number of internal cavities in the profile itself, t...

Problems solved by technology

[0003] The traditional single-layer door frame is either directly made of solid material or made of extruded profiles. However, if the extruded profiles are processed and manufactured, due to the large number of internal cavities in the profile itself, the mold core If the division of rod design is unreasonable, it is easy to cause the surface of the formed profile to be uneven, the material replenishment is not in place, and the probability of defective products is extremely high
