Technical Field

[0001] The present application relates to the technical field of testing mold manufacturing, and in particular to a test piece die for verifying material fluidity. Background Art

[0002] At present, thermoplastic elastomer TPV materials are formed by dynamic vulcanization of PP / EPDM. If the EPDM in the system is not evenly dispersed and the particle size is large, it will cause jagged edges when the product is extruded. After the TPV material is produced, it is necessary to test extrude the surface of the material to observe whether the jagged phenomenon and the transmittance appear. Usually, a test piece template needs to be extruded through the test piece die for observation and inspection.

[0003] However, the existing test piece die for verifying the fluidity of materials has the following defects: for example, during the inspection, the thickness of the extrusion template cannot be adjusted according to customer needs, and the sawtooth phenomenon and light transmittance of templates with different thicknesses cannot be tested.

[0010] Further preferably, a knife groove is provided inside the support frame, and a cutting knife is slidably installed inside the knife groove.

[0011] Further preferably, a connecting flange is fixedly connected to the top of the discharge block.

[0025] 8. As Figure 1-5The test piece die for verifying the fluidity of the material shown includes a back plate 1, two first fixing frames 2 fixedly connected to the top of the front end of the back plate 1 and symmetrically distributed, two second fixing frames 3 fixedly connected to the bottom of the front end of the back plate 1 and symmetrically distributed, and two support frames 4 fixedly connected to the inner walls of the second fixing frames 3 and relatively distributed.

[0026] A discharge block 6 is installed inside the first fixed frame 2, an adjustment component for controlling the thickness of the template is installed on the top of the support frame 4, a driving component for driving the adjustment component is installed on one side of the adjustment component, and a detection component for facilitating observation of the template is installed inside the second fixed frame 3.

[0027] First, according to customer needs, the spacing of the components is controlled and adjusted through the driving component, and then the molten plastic enters the discharge block 6. At this time, the molten plastic needs to be discharged from the bottom of the discharge block 6 through the extrusion of the discharge device at the top of the discharge block 6. When discharged, the molten plastic contacts the outside air and then cools down quickly. Then the serration phenomenon and light transmittance of the template can be observed through the detection component.

[0028] The adjustment component includes a first mounting frame 8, a second mounting frame 9 and a roller 16. The first mounting frame 8 is fixedly connected to the top of the support frame 4 and close to one end of the back plate 1. The second mounting frame 9 is slidably installed on the top of the support frame 4. There are two rollers 16 that are movably installed on the top of the first mounting frame 8 and the second mounting frame 9 in sequence. First, the second mounting frame 9 is driven by the driving component to move toward the direction of the first mounting frame 8, and at the same time, the two rollers 16 are driven to move, so that the distance between the two rollers 16 can be adjusted. Then the molten plastic passes through the middle of the two rollers 16 and is squeezed into the required thickness by the two rollers 16.

[0029] The driving assembly includes a slide bar 10, a slide hole 11, a mounting block 12, a screw rod 13, a screw hole 14 and a driving motor 15. The slide bar 10 has two fixed connections on one side of the first mounting frame 8, two slide holes 11 are opened on one side of the second mounting frame 9 and correspond to the slide bar 10, and two mounting blocks 12 are fixedly connected to the first mounting frame 8 and the other side of the second mounting frame 9 in sequence. The screw rod 13 is movably installed in the mounting block 12 on the first mounting frame 8, and a screw hole 14 is opened inside the mounting block 12 on the second mounting frame 9 and corresponds to the screw rod 13. The driving motor 15 is installed at the rear end of the screw rod 13. When the adjustment assembly needs to be adjusted, the driving motor 15 is started to drive the screw rod 13 to rotate. Through the rotation of the screw rod 13, the second mounting frame 9 moves toward the direction of the first mounting frame 8. At the same time, the slide bar 10 can make the second mounting frame 9 slide smoothly.

[0030] The detection component includes an LED flat panel light 18 and a rectangular magnifying glass 19. The LED flat panel light 18 is fixedly installed on the front end of the back panel 1, and the rectangular magnifying glass 19 is installed on the front end of the second fixing frame 3 by bolts. The extruded template is discharged from the bottom of the two rollers 16. At this time, the light transmittance of the template can be observed through the light emitted by the LED flat panel light 18, and the serration phenomenon of the template can be more clearly observed through the rectangular magnifying glass 19.

[0031] A knife groove 5 is provided inside the support frame 4 , and a cutting knife 17 is slidably installed inside the knife groove 5 . After the inspection is completed, the template is cut by the cutting knife 17 .

[0032] The top of the discharging block 6 is fixedly connected with a connecting flange 7. When in use, the device is fixed to the discharging device through the connecting flange 7.

[0033] Working principle: First, fix the equipment on the discharging device through the connecting flange 7, and then adjust the template thickness according to the customer's requirements. When adjusting, start the drive motor 15 to drive the screw rod 13 to rotate. When the screw rod 13 rotates, the second mounting frame 9 moves toward the direction of the first mounting frame 8. At the same time, the slide bar 10 can make the second mounting frame 9 slide smoothly, and at the same time drive the movement of the two rollers 16, so that the spacing between the two rollers 16 can be adjusted. Then the molten plastic enters the discharging block 6. At this time, the molten plastic needs to be discharged from the bottom of the discharging block 6 through the extrusion of the discharging device at the top of the discharging block 6. Then the molten plastic passes through the middle of the two rollers 16 and is squeezed into the required thickness by the two rollers 16. Then the molten plastic contacts the outside air and then cools quickly. At this time, the light emitted by the LED flat panel lamp 18 can be used to observe the light transmittance of the template. At the same time, the serration phenomenon of the template can be more clearly observed through the rectangular magnifying glass 19. After the inspection is completed, the template is cut by the cutting knife 17.
