DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0036] The specific embodiment of the present invention provides a one-machine multi-mode rapid mold change foam molding machine, as shown in the attached Figure 1 As shown, it includes a frame 1, a fixed mold mounting frame 2, a movable mold mounting frame 3, a mold loading trolley 4 and a mold 5. The frame 1 is used to install mechanisms such as the fixed mold mounting frame 2 and the movable mold mounting frame 3. The number of fixed mold mounting frames 2 and movable mold mounting frames 3 installed is two or more. At the same time, the number of mold loading trolleys 4 and molds 5 also needs to be two or more. The mold can be installed on the mold loading trolley 4 according to actual needs. A track 6 is provided on the frame 1. The mold loading trolley 4 is slidably set on the track 6. The track 6 is used to guide the mold loading trolley 4 to the fixed mold mounting frame 2 and the movable mold mounting frame 3 to complete the installation in sequence. When the mold 5 needs to be replaced or installed, only the mold loading trolley 4 installed with different molds 5 is placed on the corresponding track 6, and the mold loading trolley 4 can be controlled to travel to the fixed mold mounting frame 2 and the movable mold mounting frame 3 to complete the installation of the mold 5.

[0037] In order to further facilitate installation and avoid manual installation, a first connecting part 7 can be set on the fixed mold mounting frame 2, a second connecting part 8 can be set on the movable mold mounting frame 3, and a third connecting part 9 and a fourth connecting part 10 can be set on the mold 5. Since the mold 5 includes a punch 501 and a die 502, the third connecting part 9 and the fourth connecting part 10 are respectively arranged on the die 502 or the punch 501, wherein the first connecting part 7 can be detachably connected to the third connecting part 9, and the corresponding second connecting part 8 can be detachably connected to the fourth connecting part 10.

[0038] As attached Figure 3 And attached Figure 6 As shown in the present application, the third connecting part 9 provided is arranged on the die 502, and the fourth connecting part 10 is arranged on the punch 501. The punch 501 and the die 502 are detachably connected. When the mold 5 is located on the mold loading trolley 4 and is not installed on the fixed mold mounting frame 2 and the movable mold mounting frame 3, the punch 501 and the die 502 are both arranged on the mold loading trolley 4.

[0039] The first connecting portion 7 provided in the specific embodiment of the present application is as shown in the attached Figure 5 The figure shows a first driving mechanism 701, a transmission mechanism 702 and a connecting mechanism 703, wherein the first driving mechanism 701 can be a cylinder or a motor that can be remotely controlled and can provide linear power, the transmission mechanism 702 is used for transmission, one end of the transmission mechanism 702 is connected to the first driving mechanism 701 and the other end is connected to the connecting mechanism 703, and the connecting mechanism 703 is also slidably connected to the fixed mold mounting frame 2, so that the transmission mechanism 702 is slidably connected to the fixed mold mounting frame 2.

[0040] The transmission mechanism 702 can be in the form of a connecting rod structure, which is connected to the first driving mechanism 701. The first driving mechanism 701 can drive the connecting rod to move back and forth. A connecting mechanism 703 is provided on the connecting rod. In order to strengthen the connection between the die 502 and the fixed die mounting frame 2 to be more stable, a plurality of connecting mechanisms 703 can be provided on the connecting rod. The connecting mechanism 703 is in the form of a hook structure, the hook end of the hook faces the direction of the die loading trolley 4 and the die 5, the tail end of the hook is hinged to the transmission mechanism 702, and the hook is also hinged to the fixed die mounting frame 2. When the connecting rod moves in a straight line, it can drive the hook to swing, and then cooperate with the third connecting portion 9 of the hanging rod structure, the hook is hooked on the hanging rod under the drive of the first driving mechanism 701, so as to realize the detachable connection between the die 502 and the fixed die mounting frame 2.

[0041] Since the die 502 needs to be firmly connected to the fixed die mounting frame 2, it is also necessary to design multiple first connection parts 7, which are distributed on the four sides of the fixed die mounting frame 2. At the same time, the third connection parts 9 on the die 502 are also arranged in multiple numbers distributed on the four sides of the die 502.

[0042] The second connecting portion 8 provided in the specific embodiment of the present application is as shown in the attached Figure 2 As shown, it includes a second driving mechanism 801 and a connecting rod 802 connected to the second driving mechanism 801. The second driving mechanism 801, like the first driving mechanism 701, can adopt a device that can provide linear power, such as a cylinder or a motor. The connecting rod 802 is used for detachable connection with the fourth connecting part 10. In order to ensure a stable connection between the punch 501 and the movable mold mounting frame 3, the number of the second connecting parts 8 can be two or more.

[0043] In order to specifically realize the connection between the connecting rod 802 and the fourth connecting part 10, the connecting rod 802 can be provided with a strip hole 11, and the strip hole 11 is used to pass through and limit the fourth connecting part 10, so the width of the first end of the strip hole 11 can be set to be greater than the width of the second end, as shown in the attached Figure 2 As shown, the fourth connection part 10 as a whole can be a rod body, and the fourth connection part 10 can be inserted from the first end of the strip hole 11 with a larger width. As the connecting rod 802 moves, the second end of the strip hole 11 moves to the fourth connection part 10, thereby limiting the fourth connection part 10 from being pulled out. Specifically, the fourth connection part 10 includes a first connection end 1001, a second connection end 1002, and a tightening part 1003 arranged between the first connection end 1001 and the second connection end 1002. One end of the tightening part 1003 is connected to the first connection end 1001, and the other end is connected to the second connection end 1002. The first connecting end 1001 is connected to the punch 501 and can be connected to the punch 501 by bolts. The second connecting end 1002 can be inserted into the strip hole 11 from the first end. The diameter of the tightening part 1003 is smaller than the first connecting end 1001, and the diameter of the tightening part 1003 is larger than the diameter of the second connecting end 1002. When the connecting rod 802 moves, the strip hole 11 will also move. At this time, after the second connecting end 1002 moves to the tightening part 1003, the fourth connecting part 10 can be restricted by the connecting rod 802, thereby finally realizing the detachable connection between the punch 501 and the movable mold mounting frame 3.

[0044] The present application provides a plurality of bar holes 11 which are evenly distributed on the connecting rod 802. The movement of the connecting rod 802 drives the movement of the plurality of bar holes 11. The corresponding fourth connecting parts 10 are multiple in number, and the connection stability of the punch 501 is improved by connecting at multiple positions.

[0045] Since the connecting rod 802 needs to be restricted to move in a certain direction and avoid arbitrary movement, this can be achieved by setting a limit sleeve 12, wherein the limit sleeve 12 is fixedly set on the movable mold mounting frame 3, and the number of the limit sleeves 12 is multiple and evenly arranged on the movable mold mounting frame 3. The limit sleeve 12 is provided with a through hole in the same direction as the connecting rod 802, and the connecting rod 802 is passed through the through hole to achieve a sliding connection between the limit sleeve 12 and the connecting rod 802. The most stable method is to set the limit sleeve 12 at a position corresponding to the strip hole 11, and also set a perforation on the limit sleeve 12. When the second connecting end 1002 passes through the strip hole 11, it also passes through the perforation to reinforce the contact position between the second connecting end 1002 and the strip hole 11.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
