深筋产品螺栓固定模具结构

Abstract

本实用新型涉及一种深筋产品螺栓固定模具结构，用于一次摆放螺栓和固定螺栓固定的注塑模具，包括滑块结构、螺栓、定位结构，滑块结构具有二次滑动动作的滑块，二次滑动动作的滑块在开模后滑到指定的位置和再滑动到所需距离后分别在滑块的上、下镶针上安装螺栓；且镶针与螺栓配合连接处增设定位结构。本实用新型的滑块的动作分批次完成，模具通过增加了该结构，同时满足滑块上下分批装螺栓的动作；镶针上增加定位结构，可以满足螺栓不同的批次上因内孔尺寸公差的大小来满足螺栓在安装后能很好的固定在滑块的底部，产品在注塑后不低于产品的表面。

Claims

1. A deep rib product bolt fixture mold structure for a one-shot bolt placement and bolt fixation injection mold, characterized by, It includes a slider structure, bolts, and positioning structure. The slider structure is a slider with a two-stage sliding action. After the slider slides to the designated position and then slides to the required distance after the mold is opened, bolts are installed on the upper and lower inserts of the slider respectively. Furthermore, a positioning structure is added at the connection between the insert and the bolt.

2. The bolt fixing mold structure for deep-ribbed products according to claim 1, characterized in that, The upper and lower pins are each fitted with two bolts, for a total of four bolts.

3. The bolt fixing mold structure for deep-ribbed products according to claim 1, characterized in that, The positioning structure consists of the internal thread of the bolt and an elastic steel ball on the head of the insert pin.

4. The bolt fixing mold structure for deep-ribbed products according to claim 3, characterized in that, When the bolt is inserted into the insert, the elastic steel ball on the head of the insert engages with the internal thread of the bolt, thereby positioning the bolt on the head of the insert.

5. The bolt fixing mold structure for deep-ribbed products according to claim 4, characterized in that, The inner diameter of the bolt's internal thread is slightly larger than the outer diameter of the pin head.

6. The bolt fixing mold structure for deep-ribbed products according to claim 4, characterized in that, The head of the insert has two elastic steel balls arranged in a front-to-back manner, and the distance between the two elastic steel balls is adapted to the pitch of the bolt's internal thread.

7. The bolt fixing mold structure for deep-ribbed products according to claim 1, characterized in that, Supports are added at the corresponding positions of the bolts in the mold cavity, and the bolt displacement is offset by the action of the data machine during injection molding.
