Specifically, a wear-resistant part 80 is arranged on one side of the third slide block 421 away from the rear mold core 10; when one side of the third slide block 421 away from the rear mold core 10 is slidably connected to the second inclined plane I, the wear-resistant part 80 abuts against the second inclined plane I. In this embodiment, in order to prolong the service life of the third slider 421, the wear-resistant member 80 may be disposed on a side of the third slider 421 away from the rear mold core 10, and the wear-resistant member 80 abuts against the second inclined surface I to prevent the third slider 421 from being damaged by friction.
Specifically, one side of the first slider 20, which is far away from the rear mold core 10, is provided with an adjusting groove K which runs through the first slider 20, and the multistage slider demolding device 100 further comprises: the inclined guide post 90 comprises a vertical part 91 and an inclined part 92, the vertical part 91 is arranged in the adjusting groove K, the inclined part 92 has the same inclined direction as the adjusting rod 422, and the vertical part 91 is fixed relative to the shovel base 70; when the inclined guide post 90 moves upward, the shovel base 70 and the fixing member 60 move upward synchronously to drive the third slider 421 to be away from the rear mold core 10, and when the inclined portion 92 enters the adjusting groove K, the first slider 20 abuts against the inclined portion 92 and slides under force, and the sliding direction of the first slider 20 is the same as that of the third slider 421. In this embodiment, in order to reduce the demolding process, an adjusting groove K penetrating through the first slider 20 may be provided on a side of the first slider 20 away from the rear mold core 10, and an inclined guide post 90 having a vertical portion 91 and an inclined portion 92 is provided, where the vertical portion 91 is relatively fixed to the fixing member 60, the vertical portion 91 is disposed in the adjusting groove K, an inclined direction of the inclined portion 92 is the same as an inclined direction of the adjusting rod 422, a height of the vertical portion 91 is smaller than a height of the inclined portion 92, the vertical portion 91 of the inclined guide post 90 is used as a driving component for demolding of the second glue position surface B, when the second glue position B is demolded, the inclined guide post 90 moves upward, the vertical portion 91 drives the shovel base 70 and the fixing member 60 to move upward synchronously, and the adjusting rod 422 drives the third slider 421 away from the rear mold core 10 under a force until the second glue position B realizes demolding; however, the product in the first mold cavity is not yet demolded, at this time, the inclined portion 92 is driven to continue to move towards the adjusting groove K until the inclined portion 92 abuts against the groove wall of the adjusting groove K, and since the inclined direction of the inclined portion 92 is the same as the inclined direction of the adjusting rod 422, the first slider 20 slides under the force, and the sliding direction of the first slider 20 is the same as the sliding direction of the third slider 421, so that the first slider 20 is separated from the rear mold core 10, and the demolding of the first glue position surface a is realized.
The invention provides an automobile functional part mold, which comprises any one of the multi-stage slide block demolding device 100 and a bottom plate (not shown); the driving assembly (not shown) is disposed on the bottom plate, the driving assembly is fixedly connected to the demolding assembly 40, and the specific structure of the multistage slider demolding device 100 refers to the above embodiments.
