Top Hose Adapter

Surface Finishing of Top Hose Adapter – Polish / Texture

Surface treatment is crucial in the manufacturing of plastic products. Ensure that the blue surface marked as mark 1 in the picture is polished to a B2 rating, while the green surface receives a textured VDI 3400-24.

The Parting Line Design of Top Hose Adapter

In mold design, parting lines, and slider lines are critical to the injection molding process. The red line represents the parting line of the top hose adapter product, while the blue lines indicate the parting lines of the sliders.

The Draft Angle Analysis of Top Hose Adapter

Picture 1: 

Add a 0.5-degree draft angle to the green surfaces specified in Figure 1. To achieve this adjustment, the cavity geometry can be altered by cutting the material, which ensures smoother part demolding, reduces potential problems in production, and improves product quality.

Picture 2: 

When designing the mold, add a 0.5-degree draft angle to the green surfaces specified in marked 1 and a 0.2-degree draft angle to the green surfaces specified in marked 2. To achieve this adjustment, the core geometry can be altered by cutting the material.

Picture 3:

Add a 0.5-degree draft angle to the green surfaces specified in Figure 1. To achieve this adjustment, the slider can be altered by cutting the material, which ensures a smoother part demolding, reduces potential problems in production, and improves product quality.

Picture 4:

In Fig. 4, No. 1, it is recommended that an additional 0.1 to 0.2 degrees of draw angle be added to the red surface. This adjustment can be achieved by cutting the material, especially to ensure the smooth operation of the slide during the demolding process.

Slider Design of Top Hose Adapter

The slider design is an important aspect in the manufacture of injection molds, which involves the precise arrangement of sliders in the mold structure and the design of corresponding slide trajectories and channels to achieve specific shapes or structural requirements in the top hose adapter product. The marked 1 is slider inserts, and the marked 2 of blue lines are slider parting lines.

Ejector Design Of Top Hose Adapter

Confirm the ejector position to ensure that the position of the ejector pin doesn’t interfere with the slide. Since the circled-out position is the sealing surface, it is recommended that it is best not to lower the ejector pin, and the ejector pin position can be changed to the marked 1 position section. During the mold design process, it is crucial to avoid conflict between the slider and ejector position, which not only prevents damage to the mold but also ensures a smooth demolding process and high-quality top hose adapter product output.

Gate Type & Location & Size of Top Hose Adapter

The dimensions of the valve gate of the hot runner system are Ø3 mm. To ensure the accuracy and stability of the gate, we recommend making a small flat area around the gate with dimensions of Ø4 mm and a thickness of 0.15 mm. This flat area helps to optimize the flow of the material and the pouring effect.

The Problem Points of Top Hose Adapter

Picture 1

The circled area in the image shows a case of slider sinking. We recommend adding material to this area, as indicated by the red surface in the first position of the image. This adjustment will eliminate the sagging issue, ensuring proper slider fit within the mold and improving demolding. It will also enhance the product’s structural integrity and finish quality.

Picture 2

The red surface area inside the holes has an undercut. We suggest modifying this by removing the step and fillet design in this section, as shown in the image. Eliminating these features will prevent potential demolding issues, simplify mold design, and improve machining accuracy and part quality.

Reasonable mold layout design needs to take into account factors such as the injection molding machine, mold, cooling system, operating space, and molded product removal to ensure the efficient operation of the production process and the quality of the final product.

Before delivery, we will fully maintain and clean the molds to make sure the surface of the molds are smooth and internal impurities. Then anti-shock material and protective padding are packed and put into wooden crates and labeled with model and quantity information.
