Embodiment 1

[0019] Embodiment 1, combining figure 1 and figure 2 , the left B-pillar upper decorative plate injection mold, including the movable mold 1 and the fixed mold matched with the movable mold, the inner wall of the cavity of the movable mold 1 is provided with a parting part 2 protruding from the inner wall of the movable mold cavity, and the parting part 2. The surface facing the fixed mold is a parting surface, and the parting surface 21 is a planar structure. The parting surface 21 is a square ring structure, and the inner contour line of the parting surface 21 is parallel to its outer contour line. The parting surface 21 of the parting part 2 divides the cavity of the movable mold 1 into two parts. The inner part is a closed cavity 11, and its outer part cooperates with the inner wall of the fixed mold to form an injection molding cavity.

[0020] The parting surface 21 is provided with a cutter 3, the cutter 3 includes a cutter body 31 and four claw-shaped parts 32, the ...

Embodiment 2

[0022] Example 2, combined with figure 1 , the fabric cutting method, using the above-mentioned left B-pillar upper decorative plate injection mold, including the following steps: Step 1, through the cloth hanging needle arranged on the movable mold 1, the fabric is laid flat on the cavity inner wall of the movable mold 1 . Step 2, the movable mold 1 moves to the fixed mold together with the fabric to realize mold closing. During the mold closing process, the tops of the ring-shaped convex ribs of the tool body 31 and the straight convex ribs of the claw-shaped part 32 are moved to their corresponding positions. The fabric touches through to realize the cutting of the fabric. Cutter main body 31 cuts out square hole on fabric, and rest material stays in closed cavity 11, and four claws 32 cut out three otches on the four corners of the square hole that cut out on fabric respectively, facilitates The fabric is stretched at the four corners of the square hole when the product ...

Abstract

The invention discloses an injection mould for a left-B-column upper decorative plate. The injection mould comprises a movable mould and a fixed mould matched with the movable mould. The inner wall ofa mould cavity of the movable mould is provided with a parting part protruding out of the inner wall of the mould cavity of the movable mould. The parting surface, directly facing the fixed mould, ofthe parting part is of a plane structure. The parting surface is provided with a cutter. The cutter comprises a cutter main body and four claw-shaped parts. The cutter main body and the claw-shaped parts are fixedly connected with the parting part into a whole. The cutter main body is an annular flange of a square structure. The four corners of the cutter main body are round corners. The four claw-shaped parts are arranged on the outer sides of the four round corners of a main body part correspondingly. Each claw-shaped part is composed of three sections of straight line flanges. One ends ofthe three sections of straight line flanges are connected with the cutter main body. The other ends of the three sections of straight line flanges are in an outwards-scattering shape. The invention further discloses a fabric cutting method. According to the injection mould for the left-B-column upper decorative plate, the process of singly cutting fabrics is omitted, the technical difficulty of laying the fabrics is reduced, the time and labor are saved, the production cost is saved, the rate of finished products is increased significantly, and the production efficiency of products is improvedsignificantly.

Description

technical field [0001] The invention relates to the technical field of injection molds for automobiles, in particular to an injection mold for a decorative plate on the left B-pillar of an automobile and a fabric cutting method. Background technique [0002] The outer surface of the trim panel on the left B-pillar of the car needs to be pasted with fabric. The usual method is to cut the fabric first, glue it to the outer surface of the upper trim panel with glue, and then cut off the rest of the fabric. The process is cumbersome and environmentally friendly. Poor, low service life, high technical requirements for workers, low product yield. According to the quality requirements of the product, the trimmed fabric is currently placed in the injection cavity of the mold. After the injection molding is completed, the fabric and the product are combined into one without the use of glue, which has good environmental performance. The combination is firmer and smoother. Before the...
