Description

Technical Field

[0001] This application relates to the field of automotive floor mat processing equipment technology, and in particular to a molding apparatus for automotive floor mats. Background Technology

[0002] For some plastic blanks, such as rubber, plastic or silicone, the blank is pressed into the mold cavity by a hot press plate through a molding process. The air between the plastic blank and the cavity is squeezed out. Because the plastic blank has poor air permeability, after molding, the plastic blank will stick too tightly to the bottom of the cavity due to the negative pressure, making it difficult to remove the molded plastic blank from the cavity.

[0003] In practical use, it was found that the traditional device is not reasonably designed in the demolding process and lacks an efficient ejection mechanism. It often requires manual assistance for demolding, which not only increases the labor intensity, but also makes it easy for the molded floor mats to be deformed and damaged due to external forces, affecting the product qualification rate. In addition, the manual operation is inefficient and cannot adapt to the problem of large-scale automated production. Therefore, we propose a molding device for automotive floor mats to solve the above problems. Utility Model Content

[0004] The purpose of this application is to provide a molding device for car floor mats, which facilitates material handling and solves the problems of difficult demolding and easy product damage caused by traditional devices.

[0011] By adopting the above technical solution and setting an ejection mechanism, high-pressure gas can enter the hollow seat through the inflation pipe and then be blown upward through the vent pipe. The generated air pressure can push the support plate to move upward against the spring force, thereby ejecting the formed foot pad from the die seat and detaching the foot pad from the mold cavity, making it easier for manual or robotic arms to pick up the material.

[0012] A further configuration of this application is as follows: the reset mechanism includes two first connecting plates, two second connecting plates, and a spring. The first connecting plates are fixedly installed on both sides of the top of the support plate, the second connecting plates are fixedly installed on the top of the first connecting plates, and the spring is fixedly installed on the bottom of the second connecting plates.

[0026] (2) Through the cooperation of piston rod, piston rod, air inlet pipe and air outlet pipe, it is possible to realize that after the pressure mold is formed, the hydraulic cylinder output shaft retracts and drives the piston plate to move upward, so that high pressure gas can enter the hollow seat through the air inlet pipe and then blow out upward through the air outlet pipe. The generated air pressure can push the support plate to overcome the spring force and move upward, so as to push the formed foot pad out of the die seat, so that the foot pad is separated from the mold cavity, making it convenient for manual or robotic arm to pick up the material.

The piston rod 302 is located outside the hollow seat 4 and the punch seat 203.

[0037] Specifically, the ejection mechanism includes an inflation pipe 401 and a vent pipe 402. The same inflation pipe 401 is provided between the piston cylinder 3 and the hollow seat 4. One end of the inflation pipe 401 is located above the piston plate 301. The same vent pipe 402 is provided between the hollow seat 4 and the die seat 101. The top end of the vent pipe 402 is adapted to the bottom of the support plate 5.

[0038] Specifically, the reset mechanism includes two first connecting plates 501, two second connecting plates 502, and a spring 503. The first connecting plates 501 are fixedly installed on both sides of the top of the support plate 5, the second connecting plates 502 are fixedly installed on the top of the first connecting plates 501, and the spring 503 is fixedly installed on the bottom of the second connecting plates 502.

[0039] Specifically, a pressure sensor 6 is provided between the punch seat 203 and the lifting plate 202, and the pressure sensor 6 is electrically connected to the controller 10.

[0040] Specifically, a heating seat 7 is provided at the bottom of the punch seat 203, and the heating seat 7 is electrically connected to the controller.

[0042] Specifically, a first connecting pipe 303 and a second connecting pipe 304 are provided on the outside of the piston cylinder 3. The first connecting pipe 303 is located above the piston plate 301, and the second connecting pipe 304 is located below the piston plate 301. Both the first connecting pipe 303 and the second connecting pipe 304 penetrate the bottom box 1.

[0043] Specifically, a one-way valve is installed in both the first connecting pipe 303 and the second connecting pipe 304.

[0044] In this application, during operation, the rubber blank is first placed on the top of the support plate 5 inside the die holder 101. The hydraulic cylinder 201 is activated by the controller 10, and its output shaft can drive the lifting plate 202 and the punch holder 203 to move the die downward. At this time, the piston rod 302 moves down synchronously with the lifting plate 202, causing the piston plate 301 to slide downward in the piston cylinder 3. The space above the piston plate 301 increases, and the one-way valve in the first connecting pipe 303 opens. Outside air enters the upper cavity of the piston cylinder 3 through the first connecting pipe 303 to replenish the gas and store energy for the subsequent ejection mechanism. When the punch holder... After the mold 203 and the die holder 101 are closed, the plastic blank can be heated to a molten state by the heating seat 7. The molding pressure can be monitored in real time by the pressure sensor 6 and fed back to the controller 10. By adjusting the pressure of the hydraulic cylinder 201, the mold cavity pressure is kept stable. This achieves the purpose of ensuring that the blank is fully filled into the mold cavity through pressure holding, forming the precise contour of the car floor mat. After the molding is completed, the output shaft of the hydraulic cylinder 201 retracts, which can drive the lifting plate 202 to move upward. The piston rod 302 can pull the piston plate 301 to move upward. At this time, the one-way valve of the first connecting pipe 303 is closed. The air pressure above the piston plate 301 increases sharply. High-pressure gas enters the hollow seat 4 through the inflation pipe 401 and is then blown upward through the vent pipe 402. The generated air pressure pushes the support plate 5 upward against the elastic force of the spring 503, thus ejecting the formed foot pad from the die seat 101 and detaching it from the mold cavity. This facilitates manual or robotic arm material removal, thereby solving the problems of difficult demolding and easy product damage associated with traditional devices. After material removal, the support plate 5 slides downward under the reset action of the spring 503, passing through the first connecting plate 501, The second connecting plate 502 drives the smooth descent, awaiting the next feeding. Throughout the process, the slide bar 8 slides on the top plate 2, ensuring the straightness and stability of the lifting plate 202's movement and avoiding dimensional errors caused by displacement during molding. The second connecting pipe 304 closes its one-way valve when the piston plate 301 moves down to prevent gas leakage, and opens when it moves up to balance the air pressure below the piston plate 301. This ensures accurate gas flow logic of the ejection mechanism, realizing an automated cycle of "molding-heating-forming-ejection," thereby improving the efficiency and yield of automotive floor mat molding.
