DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a clamping device for foaming equipment, including a support plate 1, two support frames 2 are fixed on the support plate 1, an upper clamp 4 is slidably fitted between the two support frames 2, a lower clamp 3 is fixed on the support plate 1, a groove 9 is opened in the lower clamp 3, the groove 9 corresponds to the upper clamp 4, a pressure detection structure is fixed in the groove 9, a push-out structure is installed at the bottom of the groove 9, a placement plate 20 is installed in the groove 9, and a limiting structure is installed between the placement plate 20 and the groove 9.

[0022] In this embodiment, a first slide groove 5 is opened in the support frame 2, a first slider 8 is fixed to the side of the upper clamp 4, the first slider 8 corresponds to the first slide groove 5, a hydraulic cylinder 6 is fixed to the lower side of the support plate 1, and the output end of the hydraulic cylinder 6 is fixedly connected to the upper clamp 4.

[0023] Specifically, when filling and foaming are required, the mold is placed on the placement plate 20, and then the hydraulic cylinder 6 is started, so that the hydraulic cylinder 6 drives the upper clamp 4 to move downward, thereby squeezing the mold so that the mold enters the groove 9, and filling and foaming can be performed.

[0024] The pressure detection structure includes a plurality of first strain gauges 10, a plurality of second strain gauges 11 and a plurality of third strain gauges 12. The first strain gauges 10, the second strain gauges 11 and the third strain gauges 12 are all fixed on the side walls of the groove 9. The first strain gauges 10, the second strain gauges 11 and the third strain gauges 12 are arranged downward in sequence. The limiting structure includes a plurality of second sliders 19 fixed to the peripheral side of the placement plate 20. A second slide groove 18 is opened in the groove 9, and the second slide groove 18 corresponds to the second slider 19.

[0025] Specifically, when the mold enters the groove 9, the lower mold squeezes the third strain gauge 12 and the upper mold squeezes the first strain gauge 10. By judging the pressure, it is determined whether the upper mold and the lower mold are misaligned, so that the upper mold and the lower mold can be manually adjusted in time.

[0026] When the foam overflows, the overflowing foam squeezes the second strain gauge 11, and the foaming equipment can be shut down in time, thereby preventing the foam from overflowing and reducing the waste of foaming.

[0027] The ejection structure includes multiple springs 13, one end of the spring 13 is fixed to the bottom of the groove 9, and the other end of the spring 13 is fixedly connected to the placement plate 20. The ejection structure also includes a push rod 14. A through groove 15 is opened in the support plate 1, and the through groove 15 is connected to the groove 9. The push rod 14 corresponds to the through groove 15. A piston 17 is fixed to one end of the push rod 14. An air pipe 16 is fixed to the lower side of the support plate 1, and the air pipe 16 is connected to the through groove 15.

[0028] Specifically, after the foaming and filling is completed, the upper clamp 4 moves upward and resets, so that the spring 13 rebounds and pushes the support plate 1 out.

[0029] When the mold is heavy, the elastic force of the spring 13 cannot push out the support plate 1, and the air pipe 16 can be used to inflate the through groove 15, so that the piston 17 drives the push rod 14 to move upward, and the support plate 1 can be pushed upward with the help of air pressure, which makes it convenient to take the mold.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
