[0002] The rear outer tub of the drum washing machine is one of the important components of the drum washing machine. This piece was originally assembled from the rear outer tub of the functional parts and the computer board installation box. When the two are separately injected, two sets of molds need to be opened, occupying two Injection molding machine, low production efficiency, cumbersome later assembly
However, if the rear outer barrel and the computer board installation box are integrated into one piece, and the injection molding is carried out on the same injection molding machine, the mold structure will be more complicated, there will be undercuts and core pulling in different directions, the core pulling is difficult, and the scrap rate high, difficult to achieve

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Such as Figure 1-6 As shown, the slider multi-directional core-pulling mechanism of the injection mold includes a slider 1, which is slidably installed on the movable mold, and the slider 1 is formed with a bent pin groove 101, and the bent pin groove 101 There is a bent pin 2 penetrating inside, and the bent pin 2 is fixed on the fixed mold. An inclined roof groove 103 is also formed inside the slider 1, and an inclined roof is installed inside the inclined roof groove 103, so that The lifter includes a lifter head 12 that makes the undercut 13 of the product formed and a lifter rod 4 that connects the lifter head 12, as figure 2 As shown, the product undercut 13 is located in the product A area.

[0020] Among the above-mentioned technical schemes: Figure 4 As shown, the side of the slider 1 is provided with an auxiliary slider 8, and one...

Abstract

The invention relates to a multi-direction core-pulling mechanism for a slide block of an injection mold. The mechanism comprises the slide block slidably mounted on a movable mold. A curved pin groove is formed in the slide block, a curved pin is arranged in the curved pin groove in a penetrating manner, the curved pin is fixed to a fixed mold, an obliquely arranged angle ejector slot is also formed in the slide block, an angle ejector is arranged in the angle ejector slot in a penetrating manner, the angle ejector comprises an angle ejector head which is reversely buckled and formed on a product and an angle ejector rod connected to the angle ejector head. Compared with the prior art, a back outer barrel and a computer plate mounting box are integrated as one part for injection molding production. By arranging the angle ejector and an auxiliary slide block on the slide block, core pulling in different parts and in different directions is achieved, so that the mold can be demolded smoothly, the mold structure is simplified and the production efficiency is improved.
