Sweeping Robot Moulding

In addition, our company has established cooperative relationships with plastic raw material suppliers, printing manufacturers, etc. to ensure the supply of raw materials and printing quality. Through our rich experience and perfect supply chain, our company can provide customers with high-quality customized Sweeping robot products to meet their specific needs. At the same time, we have 10 years of professional foreign trade service experience, understand the foreign trade process, and better serve our customers. For Sweeping robot products, we can make corresponding plastic parts, which is mainly done through injection molds.

The production of injection molds for sweeping robots needs to take into account complex structural molding, high precision requirements and production efficiency

1. Core design points:

1) The outer shell of sweeping robots often contains multi-directional undercut structures (such as roller brush cover buckles and sensor holes), and a combination of front mold sliders (T-slots or hydraulic drives) and rear mold inclined tops is required. For example, the roller brush cover bracket needs to be embedded with a metal rod to enhance strength, and the mold needs to be designed with split inserts and a press table structure to ensure accurate positioning of metal parts and plastic coating

2) The parting surface avoids the appearance surface, and the gate is usually selected in the battery compartment or the internal hidden area. Point gates or diving injection are used to avoid affecting assembly and appearance

2. Precision core and cooling system

1) Slender cores (such as fan blade mounting holes) need to be made of high-wear-resistant steel (NAK80 or S136), and built-in copper cooling rods to improve heat dissipation efficiency and prevent deformation.

2) The four corners of the mold core are designed with 5° jaw positioning, and the mold clamping accuracy is ≤0.01mm with the guide pin and guide sleeve. Some high-precision molds are equipped with double positioning blocks (tapered first positioning block and second positioning block) to improve stability

3. Hot runner and ejection optimization

1) Hot runner system is recommended for multi-cavity molds to reduce waste and ensure melt uniformity, which is suitable for small batch multi-component synchronous production such as rear wheel guards.

2) The ejection mechanism uses Z-shaped ejector and manipulator to cooperate with demolding. Transparent parts need to avoid scratches. Some cases integrate CCD visual system to achieve automatic sorting

4. Technical difficulties and solutions

1) Complex structure one-piece molding

Problem: The shell sound guide hole or the empty tube inside the U-shaped pendant is prone to functional defects due to welding marks.

Solution: Use banana-shaped gate design + in-mold hot cutting technology to optimize the melt flow path, and monitor dimensional consistency through SPC process control

2) Insert injection molding stability

Problem: The metal rod is prone to offset or uneven rubber coating when embedded in the roller brush cover bracket.

Solution: Pre-embed positioning pins in the mold, split insert design to reserve mold repair margin, combined with liquid silicone (LSR) secondary injection molding to improve adhesion

3) Automated production adaptation

Problem: The efficiency of manual inspection of small transparent parts (such as sensor covers) is low.

Solution: Integrate CCD visual system and robotic arm to achieve automatic sorting and defect identification. Some manufacturers use 100,000-level dust-free workshops to ensure light transmittance

5 Material and process selection

1) Mold steel

Preferably choose 718H, S136 (corrosion resistance), NAK80 (high polishability), key inserts require vacuum quenching treatment to extend life

2) Injection molding parameters

Use 90-700T injection molding machine, mold temperature controller accurately controls temperature (±1℃), transparent parts require oil circulation system to reduce shrinkage deformation

3) Surface treatment

The shell often needs frosted surface or leather grain treatment, and the mold cavity uses etching process to improve anti-slip and aesthetics
