Embodiment 1
[0023] Such as figure 1 and figure 2 As shown, the mold is provided with a blowing component mounting hole, and the bottom of the blowing component mounting hole is provided with an air pipe connection hole, the air pipe connection hole is connected to the air pipe, and then connected to the main pipe, and connected to the compressed air source through the solenoid valve.
[0024] The air blowing assembly includes a piston seat and a piston, and the piston seat is installed on the mounting hole of the air blowing assembly. The top of the piston seat is flush with the mold surface, the middle contains a through hole, the top of the through hole contains a coaxial first platform, and the bottom is a sealing surface.
[0025] The piston includes a vent part, a connecting part and a sealing part. The ventilation part is provided with several ventilation holes, the ventilation holes communicate with the through hole of the piston seat, the sealing part cooperates with the sealin...
Embodiment 2
[0032] The basic structure is the same as in Embodiment 1, the difference is that a second sinking platform coaxial with it is set at the bottom of the first sinking platform, so that the vent hole on the piston vent part can be better connected with the connection part and the through hole of the piston seat. The gaps are connected. When the piston is not rising, the resistance of the airflow is smaller, and the piston has a larger wind surface, which is smoother when it rises.
Embodiment 3
[0034] The basic structure of the air blowing assembly is the same as that of embodiment 1 or embodiment 2, the difference is that a sealing ring is added between the sealing part of the piston and the bottom surface of the piston seat, and a better sealing effect can be achieved when the piston rises. For this reason, when the piston is assembled, the sealing ring should be put on the connecting part in advance.
[0035] In addition, the assembly between the piston seat and the mold can be done in the manner shown in the attached drawing. A through hole is set on the piston seat, and a threaded hole is set at the corresponding position below the through hole on the mold, and the screw is screwed to the threaded hole on the mold through the through hole. Inside. In order to keep the surface of the mold flat, the screws are countersunk screws, and the holes on the piston seat should also correspond to it.
[0036] Although the ceiling is basically used as an example in this ar...

Abstract
The invention relates to an air blowing assembly for a mold, comprising a piston and a piston base. The air blowing assembly is characterized in that the piston base is assembled in an air blowing assembly mounting hole formed in the mold in advance, and the top of the piston seat is flush with the molded surface of the mold; a through hole communicating up and down is formed in the piston base; afirst sinking table coaxial with the through hole is arranged at the top of the through hole; the bottom of the through hole is a sealing surface; the piston comprises an upper ventilation portion, alower sealing portion, and a connecting portion for connecting the ventilation portion and the sealing portion; the outer contour of the ventilation portion is in clearance fit with the first sinkingtable at the top of the through hole of the piston base; the top is flush with the piston base and the mold; the ventilation portion is provided with a plurality of vertically-through ventilation ports; the ventilation ports communicate with the through hole in the piston base; the connecting portion is located in the through hole of the piston base, and the length is larger than that of the through hole of the piston base; a certain gap is formed between the connecting portion and the through hole of the piston base to allow gas to circulate; and the bottom sealing portion is provided with asealing surface matched with the bottom of the piston base. When the piston falls down, the top of the piston is flush with the piston base and the molded surface of the mold, the sealing portion isseparated from the sealing surface of the piston base, and ventilation can be implemented. When the piston rises, the top of the piston is higher than the piston base and the molded surface of the mold, and the sealing portion is matched with the sealing surface at the bottom of the piston base to implement sealing without ventilation. The air blowing assembly can be self-sealed during air leakage, and influences on other air blowing assemblies connected with the air blowing assembly in parallel are avoided.
Description
technical field [0001] The invention relates to an air blowing assembly for a mold, in particular to an air blowing assembly with a self-sealing function for a mold. Background technique [0002] Automotive interior roofs are divided into dry process and wet process. The dry process is a cold mold with hot material. After the mold is opened, the temperature is lower, the rigidity is better, and there is no difficulty in picking up the parts. The wet process uses cold material and hot mold, and uses liquid adhesive, so the ceiling temperature is higher after the mold is opened, and the rigidity is poor. Under the trend of light weight, the rigidity requirements of many ceilings are reduced, and the rigidity is even worse when the mold is opened. Due to the vacuum effect or the slight glue sticking to the mold, the ceiling may be tightly attached to the lower mold, making it difficult to take out parts and prone to breakage. Defects, so auxiliary demoulding measures need to ...
