Inclined core pulling mechanism of automobile armrest mould

Abstract

The invention discloses an inclined core pulling mechanism of an automobile armrest mould. The inclined core pulling mechanism comprises an inclined rod (1) which is fixed on a movable mould and a slide block seat (2) which is connected to a fixed mould in a sliding manner, wherein a first inclined hole (3) which is matched with the inclined rod (1) for controlling the slide block seat (2) to slide is formed in the slide block seat (2); one end, away from the first inclined hole (3), of the slide block seat (2) is provided with an inclined surface (4); the upper end of the slide block (6) is fixedly provided with a core pulling block (7); a second inclined hole (8) is formed in the core pulling block (7); an inclined top (9) is connected in the second inclined hole (8) in a sliding manner; the end surface of one end, connected to the slide block (6), of the core pulling block (7) is provided with a groove (10); an ejector block (11) sliding up and down is connected in the groove (10) in a sliding manner; and a spring (13) is arranged between the lower end surface of the ejector block (11) and the slide block (6). Compared with the prior art, the inclined core pulling mechanism has the characteristics of being relatively simple in structure, relatively small in size, relatively low in cost, relatively good in stability of use and relatively high in yield.

Description

technical field [0001] The invention relates to an oblique core-pulling mechanism for an automobile armrest mold used for producing automobile armrest panels. Background technique [0002] The central armrest of the car is also called the armrest of the car. At first, it was used to provide elbow support for passengers. Later, it developed into a storage box in the car, including the armrest panel, which is convenient for talking, working, and reading documents. [0003] At present, in order to make the outer surface more beautiful, the car handrail generally uses a built-in buckle. The buckle is integrally formed with the panel body and is directly connected to the frame during installation. However, for comfort and relatively small volume after shrinking, the frame There is a certain slope, and the buckle is generally vertical, but the vertical buckle is easy to cause stress concentration during use due to force, and it will break when it is accommodated, so the use stabil...

[0003] At present, in order to make the outer surface more beautiful, the car handrail generally uses a built-in buckle. The buckle is integrally formed with the panel body and is directly connected to the frame during installation. However, for comfort and relatively small volume after shrinking, the frame There is a certain slope, and the buckle is generally vertical, but the vertical buckle is easy to cause stress concentration during use due to force, and it will break when it is accommodated, so the use stability is relatively poor; improve stability Generally, two solutions are adopted, one is to increase the strength of the buckle itself, that is, to increase the thickness of the buckle, but after this setting, injection defects are prone to occur, and the yield is relatively low; the other is to use an oblique buckle, and due to the There are many reinforcing ribs, so that the core-pulling space of the inclined buckle is small. The structure of the oblique core-pulling mechanism in the prior art is relatively complicated, requiring at least two external power mechanisms and the volume of the slider is relatively large, which leads to an increase in the mold volume. Large, and the maintenance of the whole core-pulling mechanism is troublesome, and the stability of use is poor
