Description

Technical Field

[0001] The utility model relates to the technical field of mold temperature controllers, in particular to a segmented temperature control module for an extruder mold. Background Art

[0002] Each process section of the extruder requires different temperature control. Generally, a segmented mold temperature controller is used to control the temperature. Each process section in the extruder equipment can be independently heated and cooled at the same time. The existing segmented mold temperature controller is usually equipped with a pulley structure for easy transportation. When the oil circulation temperature controller is in use, it needs to be connected to the external oil pipe. If the oil circulation temperature controller moves, the oil pipe may fall off.

[0003] In order to solve the above technical problems, a Chinese utility model patent with authorization announcement number CN214926404U discloses an oil circulation temperature control machine for an automatic segmented temperature control intelligent molding machine, including a box body and a temperature control system inside the box body, a universal wheel is arranged at the bottom of the box body, and a fixed component is arranged at the center of four sets of universal wheels. The stepper motor in the fixed component can drive the fixed bottom plate to move up and down. When the fixed bottom plate rises to the highest point, the height of the lower edge of the fixed bottom plate is slightly higher than the lowest point of the universal wheel, and when it falls to the lowest point, the lower edge of the fixed bottom plate is slightly lower than the lowest point of the universal wheel, so that the locking of the device is realized, and no manual lifting work is required, which is highly efficient.

[0004] However, the above-mentioned prior art has the following problems: it adds a supporting structure at the bottom of the box, increases the contact area between the box and the ground, increases the grip, and plays an effect of preventing the box from moving. However, this has high requirements on the flatness of the ground. The factory floor cannot have bumps, otherwise it will not be possible to prevent the box from moving. Therefore, it has relatively strict requirements on the environment and has a limited scope of application. Utility Model Content

[0005] The purpose of the utility model is to provide an extruder mold segmented temperature control module to solve the problem raised by the above background technology that the extruder mold segmented temperature control equipment on the market currently relies on increasing the contact area between the box and the ground to prevent the box from moving, and thus cannot adapt to all terrains.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a segmented temperature control module for an extruder die, comprising a box body, an oil tank arranged in the box body and an oil inlet conduit connected to the oil tank, the oil inlet conduit is connected to a temperature controller, the temperature controller is connected to the inlet of an oil pump, the outlet of the oil pump is connected to an oil outlet conduit, one end of the oil tank is connected to an oil return conduit, a universal wheel is arranged at the bottom of the box body, and further comprises:

[0013] As a preferred technical solution of the utility model, the connecting tube is provided with a plurality of fixed blocks about the axis line array, and a roller is rotatably connected in the fixed block, and the roller is in contact with the sliding tube.

[0014] As a preferred technical solution of the utility model, one end of the connecting pipe is connected to a connector, the outside of the connector is provided with threads, and the connector is threadedly connected to the sliding pipe port.

[0015] As a preferred technical solution of the utility model, a plurality of hydraulic rods are arranged at the bottom of the box body, the output ends of the hydraulic rods are connected to a supporting bottom plate, and the supporting bottom plate is provided with a through groove for the universal wheel to move.

[0016] As a preferred technical solution of the utility model, an internal thread groove is provided at one end of the connecting pipe, and the connecting pipe is threadedly connected to the oil outlet conduit and the oil return conduit.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figure 1-6 The utility model provides a technical solution: a segmented temperature control module for an extruder die, comprising a box body 1, an oil tank 2 arranged in the box body 1 and an oil inlet conduit 3 connected to the oil tank 2, the oil inlet conduit 3 is connected to a temperature controller 4, the temperature controller 4 is connected to the inlet of an oil pump 5, the outlet of the oil pump 5 is connected to an oil outlet conduit 6, one end of the oil tank 2 is connected to an oil return conduit 7, a universal wheel 8 is arranged at the bottom of the box body 1, and further comprises:

[0028] A connecting pipe 12 connected to the oil outlet conduit 6 and the oil return conduit 7 respectively; an inner thread groove 13 is formed at one end of the connecting pipe 12, and the connecting pipe 12 is threadedly connected to the oil outlet conduit 6 and the oil return conduit 7;

[0029] A sliding tube 14 is movably arranged in the connecting tube 12, and the sliding tube 14 is connected to a sealing ring 15. A reset structure for driving the sliding tube 14 to reset is arranged in the connecting tube 12; the reset structure comprises: a first fixing ring 16 fixedly arranged on the outside of the sliding tube 14 and a second fixing ring 18 fixedly arranged on the inner wall of the connecting tube 12; a reset spring 17 arranged between the first fixing ring 16 and the second fixing ring 18 for connecting the two;

[0030] A connection pipe 20 connected to the sliding pipe 14 and used to connect the mold; one end of the connection pipe 20 is connected to a connector 19, the connector 19 is provided with threads on the outside, and the connector 19 is threadedly connected to the end of the sliding pipe 14;

[0031] The above technical solution can buffer the pulling force on the connecting pipe 20 caused by the movement of the box body 1, and prevent the connecting pipe 20 from loosening. When in use, the connecting pipe 20 connected to the oil outlet conduit 6 is connected to the oil pipe inlet of the extruder mold, and the connecting pipe 20 connected to the oil return conduit 7 is connected to the oil pipe outlet of the extruder mold. When heating the mold, the oil pump 5 sucks the oil in the oil tank 2 into the temperature controller 4 through the oil inlet conduit 3. The temperature controller 4 is a tubular container with an electric heating wire inside. After the oil enters the tubular container, the electric heating wire heats the oil to raise its temperature. The heated hot oil is pumped into the inlet by the oil pump 5, and sent to the oil outlet conduit 6 through the outlet of the oil pump 5. The oil outlet conduit 6 sends the hot oil to the connecting pipe 12, and enters the connecting pipe 20 through the sliding pipe 14. The connecting pipe 20 sends the hot oil to the oil pipe inlet of the extruder mold. The hot oil of the extruder mold is discharged through the oil pipe outlet and enters the oil return conduit 7. The oil return conduit 7 re-enters the oil tank 2, thereby forming a closed-loop oil circuit.

[0032] When the box body 1 moves away from the extruder, the connecting tube 20 pulls the connecting head 19 to move, and the connecting head 19 pulls the sliding tube 14 to slide, thereby buffering the pulling force generated by the movement of the box body 1. Since a sealing ring 15 is provided on the outside of the sliding tube 14, it can prevent oil from leaking from the gap between the sliding tube 14 and the connecting tube 12. When the worker resets the box body 1, the pulling force of the connecting tube 20 on the sliding tube 14 disappears. Under the elastic force of the reset spring 17, the sliding tube 14 automatically resets. Compared with the prior art, it no longer relies on increasing the contact area between the box body 1 and the ground to prevent the connecting tube 20 and the oil outlet conduit 6 or the oil return conduit 7 from falling off, thereby improving practicality.

[0033] Further, such as Figure 4 As shown, the connecting tube 12 is provided with a plurality of fixed blocks 21 in an array about the axis line, and a roller 22 is rotatably connected in the fixed block 21, and the roller 22 is in contact with the sliding tube 14;

[0034] The above technical solution can further improve the buffering effect. Since the roller 22 is provided in the connecting tube 12, the sliding friction can be replaced by rolling friction. When the sliding tube 14 slides in the connecting tube 12, the friction resistance between the sliding tube 14 and the inner wall of the connecting tube 12 can be avoided, making the sliding tube 14 unable to slide.

[0035] Furthermore, Figure 3 As shown, a plurality of hydraulic rods 9 are arranged at the bottom of the box body 1, and the output ends of the hydraulic rods 9 are connected to a supporting bottom plate 10, and the supporting bottom plate 10 is provided with a through slot 11 for the universal wheel 8 to move;

[0036] The adoption of the above technical solution can further improve the buffering effect. In order to further improve the stability of the box 1, the hydraulic rod 9 is started to drive the supporting bottom plate 10 to move downward, so that the supporting bottom plate 10 is in full contact with the ground, thereby increasing the grip of the box 1. In order to improve the stability, anti-skid patterns or anti-skid protrusions can be further provided at the bottom of the supporting bottom plate 10 to increase the friction coefficient and prevent the box 1 from moving.

[0037] Working principle: when in use, the connecting pipe 20 connected to the oil outlet conduit 6 is connected to the oil pipe inlet of the extruder mold, and the connecting pipe 20 connected to the oil return conduit 7 is connected to the oil pipe outlet of the extruder mold. When the mold is heated, the oil pump 5 sucks the oil in the oil tank 2 into the temperature controller 4 through the oil inlet conduit 3. The temperature controller 4 is a tubular container with an electric heating wire inside. When the oil enters the tubular container, the electric heating wire heats the oil and raises its temperature. The heated hot oil is drawn into the inlet by the oil pump 5, and the hot oil is sent to the oil outlet conduit 6 through the outlet of the oil pump 5. The oil outlet conduit 6 sends the hot oil to the connecting pipe 12, and enters the connecting pipe 20 through the sliding pipe 14. The connecting pipe 20 sends the hot oil to the oil pipe inlet of the extruder mold. The hot oil of the extruder mold is discharged through the oil pipe outlet and enters the oil return conduit 7. The oil return conduit 7 re-enters the oil tank 2, thereby forming a closed-loop oil circuit.

[0038] When the box body 1 moves away from the extruder, the connecting pipe 20 pulls the connecting head 19 to move, and the connecting head 19 pulls the sliding pipe 14 to slide, thereby buffering the pulling force generated by the movement of the box body 1. Since the sealing ring 15 is arranged on the outside of the sliding pipe 14, it can prevent the oil from leaking from the gap between the sliding pipe 14 and the connecting pipe 12. After the worker resets the box body 1, the pulling force of the connecting pipe 20 on the sliding pipe 14 disappears. Under the elastic force of the reset spring 17, the sliding pipe 14 automatically resets. Since the roller 22 is arranged in the connecting pipe 12, the sliding friction can be replaced by the rolling friction. When the sliding pipe 14 slides in the connecting pipe 12, it can avoid the friction resistance between the sliding pipe 14 and the inner wall of the connecting pipe 12, so that the sliding pipe 14 cannot slide. Compared with the prior art, it no longer relies on increasing the contact area between the box body 1 and the ground to prevent the connecting pipe 20 and the oil outlet pipe 6 or the oil return pipe 7 from falling off, thereby improving the practicality.

[0039] In order to further improve the stability of the box 1, the hydraulic rod 9 is started to drive the supporting bottom plate 10 to move downward, so that the supporting bottom plate 10 is in full contact with the ground, thereby increasing the grip of the box 1. In order to improve the stability, anti-skid patterns or anti-skid protrusions can be further provided at the bottom of the supporting bottom plate 10 to increase the friction coefficient and prevent the box 1 from moving.
