Technical Field

[0002] When the parts of the rubber-coated shell of electric tools are made by molds, the traditional production method is to use a rubber-coated mold because different colors are required for the two parts. That is, first a hard rubber of one color is punched out, and then the hard rubber of the one color is manually placed on the soft rubber of the handle by a two-color mold. This process increases the problems caused by the secondary rubber coating, such as difficulty in product installation, compression molding, low efficiency and waste of manpower, loose rubber coating, and high defective rate.
[0003] In response to the above problems, the new mold adopts a two-color mold to produce the finished product in one shot on a two-color injection molding machine to solve the problem of the overmolding mold, but it also brings new challenges to the development of the two-color mold. Since this product not only has large dimensions but also has many side ribs and undercuts, the mold of this product needs to make a slider structure on the mold for demolding. If the ribs are deep, the clamping force on the slider is large, which increases the lateral parting force and easily causes the product to deform during the demolding process, seriously affecting the accuracy and qualified rate of the product. The current solution is to use a movable insert on the mold. After the product is formed, the movable insert is removed from the mold together with the product, and then a way is found to remove the movable insert from the product hole. However, this method is time-consuming and labor-intensive and cannot meet the requirements of mass production. Utility Model Content
