Spring structure of mold slider

Abstract

The invention discloses a spring structure of a die slider, wherein a die is provided with the slider, a template arranged under the slider, and a die cavity formed in the template; and the spring structure comprises a sliding groove formed in the template, a spring arranged in the sliding groove and a stop block fixed at the bottom of the slider, the side of the sliding groove toward the slider is open; one end of the spring is propped against one end of the sliding groove in the vicinity of the die cavity; and one side of the stop block is propped against one end of the spring far away from the die cavity. The spring structure of the die slider provided by the invention is characterized in that the size of the slider does not need to be increased because the spring is arranged in the sliding groove of the template; therefore, the thickness of the die cavity and the template does not need to be increased, and the cost of the die is saved; the position of the sliding groove on the template is flexible and not limited, so that the mounting position of the spring is quite flexible; and as the spring is arranged on the bottom of the slider, interferences with an inclined guide column and a water route cannot be caused.

Description

【Technical field】 [0001] The invention relates to a spring structure, in particular to a spring structure of a mold slider. 【Background technique】 [0002] When producing the housing of electronic products, plastic molds are usually used, and some molds need to use sliders when molding products. When molds using sliders are opened, in order to prevent the sliders from returning, usually Will be designed with a spring. [0003] see figure 1 , figure 1 It is a schematic diagram of the spring structure of the mold slider in the prior art. The mold has a template 1, a core 2, a slide block 3, a slide block insert 4, an inclined guide post 5, and a spring 6. The slider 3 has a hole near the mold core 2 , one end of the spring 6 is arranged in the hole of the slider 3 , and the other end is against the mold core 2 . [0004] However, adopting the above-mentioned structure has the following problems: 1. The slider 3 needs to be made large enough to accommodate the spring 6. In...
