Description

Technical Field

[0001] The invention relates to the technical field of automobile interior decoration production, in particular to a production and processing device and method for liquid nitrile automobile interior decoration. Background Art

[0002] Nitrile rubber sealing ring is an annular cover composed of one or several parts, fixed on a ring or washer of the bearing and in contact with another ring or washer or forming a narrow labyrinth gap to prevent leakage of lubricating oil and intrusion of foreign objects. It is a copolymer formed by the polymerization of acrylonitrile and butadiene monomers. Nitrile rubber sealing ring has the following advantages: excellent oil resistance, high wear resistance, good heat resistance and strong adhesion; it is widely used in various oil-resistant rubber products, various oil-resistant washers, gaskets, sleeves, soft packaging, soft hoses, etc. in automobiles, and has become an indispensable elastic material in the automotive, aviation, petroleum, copying and other industries. Nowadays, the molding processing of nitrile rubber sealing rings mostly adopts compression molding.

[0003] At present, the existing production and processing equipment for automobile interior has the following shortcomings in use: first, in the nitrile processing and molding of automobile gaskets, this process is to heat and melt the raw materials, and then extrude the nitrile rubber sealing ring through high pressure. The nitrile rubber seal made in this way sometimes causes adhesion and cracking of the gasket molding due to the reasons such as less oil or more resin in the formula design, too high vulcanization temperature and poor fluidity, and factors such as too thick raw materials during production. When there is only 1% to 3% damage rate in the processing equipment, it will be directly ignored, and when it occurs 10% to 30%, it will cause waste of nitrile gaskets if not handled in time. When further improvements are made, in the process of debugging data materials and components in the processing equipment, a part of the cracked defective gaskets will still be recycled and processed, which invisibly increases the cost of production and processing and reduces the requirements for molding quality.

[0004] Therefore, those skilled in the art provide a production and processing device for liquid nitrile automotive interior to solve the problems raised in the above background technology. Summary of the invention

10. A method for producing a liquid nitrile automobile interior decoration device, characterized in that: The method specifically comprises the following steps: S1: The upper mold (4) is controlled to move downwards and overlap with the bottom mold (6) through the main push rod (60) to start the molding operation. After molding, the finished product is taken out by the mechanical arm gripper (2). If there is adhesion, the nitrile gasket will crack or break due to pulling during demoulding. Then, the switch of the hydraulic push rod (10) can be turned on by the external controller. When the hydraulic push rod (10) is operated, the telescopic control is controlled, thereby driving the two-way tower plate (13) to move horizontally, so that the linkage frame (12) on one side of the movement direction rises upward, further pushing the top extension frame ( After the movement of the top extension frame (23), the rack plate (21) drives the traction gear (26) to rotate, thereby driving the transfer gear (25) to rotate and the linkage gear (27) to rotate accordingly, so that the rack plate (21) continues to rise after the material transfer cone (30) rotates by a predetermined angle, and at the same time, one of the material passing holes (32) rotates to coincide with the opening (34), and the other material passing hole (32) coincides with the reinforcing agent channel (28), and the position of the directional gravity core plate (36) remains unchanged and coincides with the opening (34). Then, when the rack plate (21) continues to rise vertically, it drives the support rod (20) to move, thereby rotating and pushing on the sliding sleeve (19), causing it to slide on the outer surface of the fixed rod (18), and after sliding, it pushes the first lever plate (16) to flip in the port plate (17), thereby pushing the pressure rod plate (59) to compress the first spring (15), and slide in the reinforcing agent channel (28), so as to drive the push piston (29) to push the supplementary liquid entering from the feed valve (14), further enter from the through hole (32), and move along the directional gravity core plate (36) ) is discharged into the opening (34) through another material passage hole (32), so that it flows into the formed gasket fed into the inner mold (11), and then the hydraulic push rod (10) is reset in the same step as above, so that the traction unit (555) is reset, the rack plate (21) and the traction gear (26) are re-engaged, and the linkage control unit (554) is further driven to reset, and the feeding unit (551) and the material transfer cone (30) are further driven to reset and seal the inner mold (11), and then the upper mold (4) is started again to re-mold the gasket in the bottom mold (6); S2: After fusion, the micro push rod (24) is operated to automatically move and retract to drive the reciprocating tooth plate (41) to reciprocate, so that the external gear (46) continuously rotates to drive the coaxial cam (45) to rotate and swing, and then reciprocates to push the limit slide plate (48) to slide in the limit slide frame (49), so that the steering push frame (44) moves outward, pushes the two swing rods (58) to move in the direction of approaching each other, and compresses the second spring (39), and further pulls the sealing plug (43) to overlap the docking rod (57). The sealing plug (43) is slid outward and the sealing plug (43) is brought out and separated from the sealing sleeve (42), so that the liquid in the stearic acid storage chamber (33) can smoothly enter the sealing sleeve (42) from the oil port (35). The drainage cover (40) has a funnel diversion effect, so that under the reciprocating overlap of the sealing plug (43) and the sealing sleeve (42), the oil is sent from the stearic acid storage chamber (33) to the inner wall of the inner mold (11) and fused with the gasket. After molding, the mechanical arm gripper (2) is started again from the external controller to clamp and take out the molded part.
