Description

Technical Field

[0001] The utility model relates to the technical field of extrusion equipment, in particular to a pressure pad heat insulation structure of an extruder and an extruder. Background Art

[0002] Extruders are widely used in the molding process of metals, plastics, and other materials. This process is often accompanied by high temperatures and high pressures. As a key component in an extruder, the pressure pad bears the immense pressure from the die during the extrusion operation and comes into direct contact with the extruded material and die. Therefore, the pressure pad must not only have excellent pressure resistance but also a certain degree of high-temperature resistance.

[0003] However, existing pressure pads for extruders often face the following problems in actual use: Because the plug needs to be heated during operation, when the plug is squeezed and contacts the pressure pad, the pressure and heat are directly transferred to the pressure pad through the contact surface, exposing the pressure pad to high temperature and high pressure for a long time. High temperatures can cause the material strength of the pressure pad to decrease, and long-term heat exposure can also cause thermal fatigue and even lead to cracking or failure of the pressure pad. This situation not only affects the normal operation of the extruder, but also increases equipment maintenance costs and shortens the service life of the pressure pad. Utility Model Content

[0004] The purpose of this application is to provide an extruder's pressure pad insulation structure to solve the problem of damage to the existing pressure pad due to long-term high temperature and high pressure during surgery; in addition, this application also provides an extruder including the extruder's pressure pad insulation structure.

[0025] The pressure pad 10 and the plug 30 are spaced apart, and a heating device 31 is provided on the plug 30. The heating device 31 is configured to heat the plug 30.

[0027] Specifically, the connecting member 20 is configured as a thermally insulating short shaft.

[0028] By fixing the connecting piece 20 between the plug 30 and the pressure pad 10, not only the influence of the high temperature of the plug 30 on the pressure pad 10 is reduced, and the material strength reduction and thermal fatigue problems of the pressure pad 10 caused by long-term heating are avoided, but also the structure is simple and easy to operate.

[0029] In one embodiment, the pressure pad 10 , the connecting member 20 and the plug 30 are coaxially arranged.

[0031] In one embodiment, the second end of the connecting member 20 is configured as a tapered shaft 23 , the end surface of the tapered shaft 23 gradually expands as it approaches the pressure pad 10 , and the tapered shaft 23 abuts against the pressure pad 10 .

[0032] By providing a tapered shaft 23 at the second end of the connecting member 20, not only the contact area between the pressure pad 10 and the connecting member 20 is increased, which facilitates uniform distribution of the extrusion force and reduces local overload, but also the overall structure is made more stable.

[0033] In one embodiment, the pressure pad 10 is provided with a first slot, which is adapted to the second end of the connector 20; the plug 30 is provided with a second slot, which is adapted to the second end of the connector 20. Through the cooperation of the first slot and the second slot, not only is the precise docking of the connector 20 with the pressure pad 10 and the plug 30 ensured, thus avoiding the influence of position deviation on the working performance of the extruder, but also the connector 20 can be effectively prevented from sliding or shifting during operation, thereby ensuring that each component is tightly fixed and significantly improving the stability of the overall structure.

[0034] In one embodiment, a first inclined surface 21 is formed at the first end of the connecting member 20 along the circumferential direction, and a second inclined surface 22 is formed at the second end of the connecting member 20 along the circumferential direction.

[0035] The cooperation between the first inclined surface 21 and the second inclined surface 22 not only provides guidance for the two ends of the connector 20 to enter the first slot and the second slot respectively, but also improves the efficiency of structural installation.
