Embodiment 1

[0050] Step 1. Injection mold preparation

[0051] In this example, the figure 1 The injection mold shown includes a fixed mold and a movable mold; the fixed mold mainly includes a thermal partition, a panel 20 and a fixed template 40 connected sequentially from top to bottom, and the movable mold mainly includes a base plate 90 and a support plate connected sequentially from bottom to top 70 and the movable template 50, the ejector plate 80 is also arranged on the bottom plate 90. The fixed template 40 cooperates with the movable template 50 to form a mold cavity for product injection inside.

[0052] combine figure 1 and figure 2 , the movable template 50 is provided with a recessed groove 501, and a first insert 51 is arranged in the recessed groove 501. The first insert 51 includes a first mold core 511, a second mold core 512 and a third mold core 513. The first mold core The core 511 is set in the concave groove 501 and has an integrated structure with the movable...

Embodiment 2

[0072] The difference from Embodiment 1 is that the second needle valve 120 is opened 9s later than the first needle valve 110, the injection pressure is 120Mpa, the temperature of the entire injection molding process is controlled at 175°C, and the injection time of the first cavity 50a lasts 14s. The injection time of the second cavity 50b lasts for 8s, and the pressure is maintained for 6s after the injection of the first cavity 50a and the second cavity 50b is completed.

Abstract

The invention discloses an injection molding method for a water bucket with a handle, which includes preparing an injection mold, providing a paired movable mold and a fixed mold; The first cavity and the second cavity are formed between the molds; Injection molding, the thermoplastic resin is brought into the first cavity and the second cavity and filled gradually; Demoulding, the movable mold is separated from the fixed mold, and the molding is removed The barrel and handle in the first cavity and the second cavity are molded at the same time in one injection molding process, and the assembly between the barrel and the handle is completed during the demoulding process, which greatly improves the production efficiency .

Description

technical field [0001] The invention relates to the technical field of polymer material molding, in particular to an injection molding method for a water bucket with a handle. Background technique [0002] Plastic buckets are generally used in daily life and work. Existing conventional plastic buckets include a staving body and a handle, and the handle is rotatably connected to the outer wall of the bucket. E.g Figure 13 to Figure 15 The structure of a plastic bucket is shown, which specifically includes a bucket body 1 and a handle 2 rotatably connected to the outer wall of the bucket. The outer wall of the barrel body 1 is provided with a clamp joint 1a, the clamp joint 1a includes a clamp head 1c, and an annular groove 1b is opened at the junction of the clamp head 1c and the barrel body 1; two ends of the handle 2 are provided with a clamp tube 2a, and the clamp tube 2a has a mounting hole 2b inside. When the handle 2 is connected to the barrel body 1, the clamp head 1...
