Problems solved by technology
However, because there are usually some barb structures on the product, the mold cannot be released according to the conventional mold release method, and the barb part and the slider cannot be demolded. If the demoulding is forced, the barb structure part of the product will be damaged. damage, thus causing the scrapping of the product. If the barb part of the product is damaged and deformed less, and it is not detected in time during the inspection process, then the defective product will affect its performance after being used in the car.

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as Figure 1~5 As shown, the present invention provides a slider core-pulling mechanism, comprising a movable mold 100, a large slider 1 is slidably provided on the movable mold 100, a small slider 2 is arranged on the large slider 1, and the large slider 1 and the The small slider 2 is relatively slidable. In this embodiment, the sliding mating surface between the large slider 1 and the small slider 2 is an inclined surface, because the two inclined surfaces can also play a certain guiding role when sliding relative to each other. In this embodiment, Among them, because the head structure of the small slider 2 is very thin, it is easy to deform during processing. If the slider is deformed, it will not be usable. Therefore, the material of the small slider 2 in the present invention is preferably Buderus 2738 die steel. The materia...

The invention discloses a sliding block core pulling mechanism. The sliding block core pulling mechanism comprises a moving mold (100). Large sliding blocks (1) are slidably arranged on the moving mold (100). A small sliding block (2) is slidably arranged on each large sliding block (1). Each large sliding block (1) is provided with a guiding through hole (1.1). Inclined guide pillars (3) are arranged between the moving mold (100) and a fixed mold. One end of each inclined guide pillar (3) is fixedly connected to the fixed mold, and the other end of each inclined guide pillar (3) slidably penetrates the corresponding guiding through hole (1.1) and is arranged on the moving mold (100). A kidney-shaped hole (2.1) is arranged on each small sliding block (2). When the moving mold (100) moves apart from the fixed mold, the inclined guide pillars (3) drive the large sliding blocks (1) to slide rightwards. When the large sliding blocks (1) slide to the preset positions, the small sliding blocks (2) slide together with the large sliding blocks (1). An ejection device (4) is arranged between each large sliding block (1) and the corresponding small sliding block (2). By means of the slidingblock core pulling mechanism, a barb position of a product can be demolded easily, and the product cannot be damaged.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to a slider core-pulling mechanism. Background technique [0002] In the auto parts industry, many accessories are plastic parts, and most of them are produced by injection molding. However, because there are usually some barb structures on the product, the mold cannot be released according to the conventional mold release method, and the barb part and the slider cannot be demolded. If the demoulding is forced, the barb structure part of the product will be damaged. damage, thus causing the scrapping of the product. If the barb part of the product is damaged and deformed slightly, and it is not detected in time during the inspection process, then the defective product will affect its performance after being used in the car. [0003] Therefore, a slider core-pulling mechanism that can make the barbs on the product easy to demould, and has an uncomplicated structure and low cost needs ...
