Description

Technical Field

[0001] The utility model relates to the technical field of transfer film adsorption transfer, in particular to a vacuum pumping device used for transfer in a mold. Background Art

[0002] In-mold transfer injection molding is a process that simultaneously completes the molding and surface decoration of injection molded parts. The decorative pattern to be transferred is formed on a transfer film in advance by printing or vapor deposition, and then the transfer film is placed between the male mold and the female mold. After the molds are closed, plastic is injected into the mold to form a plastic part and the decorative pattern is transferred to the surface of the plastic part at the same time. After the plastic is solidified, the plastic part is ejected to form a plastic part with a decorative pattern.

[0003] However, when the transfer film of the prior art is adsorbed onto the in-mold component, there is no dedicated equipment to adsorb it, but the mold with the transfer film (not yet adsorbed) is uniformly taken to the vacuum equipment for the transfer process, which is extremely cumbersome and troublesome, and the handling of the mold is time-consuming and laborious, and the mold with the transfer film cannot be transferred immediately, which greatly reduces the production efficiency of the transfer film transfer. In view of the above defects, the utility model has made improvements. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0026] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without the specific details or the specific manner described herein.

[0027] See also Figure 1-2The utility model provides a vacuum extraction device for in-mold transfer of a mold, comprising: a vacuum pump 1, an air box 2, a control valve 3, a first connecting pipe 4, a second connecting pipe 5, a supporting frame 6, and a movable base 7. The air box 2 is connected to the vacuum pump 1 through the second connecting pipe 5, and the air hole of the mold is connected to the vacuum pump 1 through the first connecting pipe 4. The control valve 3 is installed on the first connecting pipe 4, the supporting frame 6 is arranged on the lower side of the vacuum pump 1, and a movable base 7 is installed on the lower side of the supporting frame 6, and a plurality of movable wheels 8 are connected to the movable base 7.

[0028] When in use, the first connecting tube 4 is connected to the air hole of the mold. When the transfer film in the mold is laid, the vacuum pump 1 works, and then the control valve 3 is opened. The vacuum pump 1 drives the first connecting tube 4 to suck air into the mold. The gas is sucked into the air box 2 through the second connecting tube 5, and the transfer film in the mold is transferred to the components in the mold. When it is necessary to switch to the next mold for adsorption transfer, the vacuum pump 1 only needs to be pushed under the action of the moving wheel 8 to move the device to the mold area where air suction is required. Similarly, the first connecting tube 4 can be connected to the air hole of the mold.

[0029] According to some embodiments of the present application, optionally, a push rod 9 is installed on one side of the vacuum pump 1 or the air box 2, which facilitates pushing the device.

[0030] According to some embodiments of the present application, the control valve 3 may be a butterfly valve structure. The gas valve has the advantages of simple structure, small size, light weight, convenient operation and easy opening.

[0031] According to some embodiments of the present application, the moving wheel 8 may be a universal wheel structure, which makes it easier to control the moving direction and makes it easier to move to the destination.

[0032] According to some embodiments of the present application, optionally, the mobile base 7 includes a support column 71, a center seat 72, a connecting arm 73, an anti-slip foot 74, a telescopic main rod 75, a telescopic secondary rod 76, and a cylinder 77. The support column 71 is installed on the center seat 72, and the connecting arm 73 is installed around the center seat 72. The lower end of one side of the connecting arm 73 is provided with an anti-slip foot 74, and the two sides of the center seat 72 are obliquely connected with the telescopic main rod 75. The telescopic secondary rod 76 is movably and telescopically inserted into the telescopic main rod 75, and the lower side of the telescopic secondary rod 76 is connected to the moving wheel 8. The cylinder body of the cylinder 77 is installed on the telescopic main rod 75, and the rod body is connected to the telescopic secondary rod 76, and the support column 71 is connected to the supporting base frame 6. Since the vacuum pump 1 generates large vibrations when working, in order to prevent the movable base 7 from moving due to the vibration, after the device is moved to the desired area through the movable wheels 8, the cylinder 77 controls the telescopic sub-rod 76 to retract into the telescopic main rod 75, so that the anti-slip foot 74 touches the ground, which plays a role in stably supporting the vacuum pump 1. When it is necessary to move, it is only necessary to extend the rod body of the cylinder 77 to push the telescopic sub-rod 76 to move until the movable wheels 8 touch the ground, and then lift the device to move it.

[0033] According to some embodiments of the present application, the anti-skid foot 74 is optionally made of rubber material, which has a better anti-skid effect.

[0034] According to some embodiments of the present application, optionally, the telescopic secondary rod 76 is rotatably connected to the rod body of the cylinder 77 via an ear plate 78. This has the function of preventing the rod body of the cylinder 77 from getting stuck when it is extended.

[0035] According to some embodiments of the present application, the connecting arm 73 is optionally rotatably connected to the central seat 72 via the shaft plate 79. This has the function of being able to adjust the connecting arm 73 to rotate to a suitable position for supporting and preventing slipping according to needs.
