Description

Technical Field

[0001] This utility model relates to the field of rubber extrusion die processing, specifically to an automatic processing equipment for rubber extrusion dies for automotive sealing strips. Background Technology

[0002] Automotive sealing is an important indicator of overall vehicle quality, and automotive sealing strips are one of the key components that determine the quality of this indicator. They are widely used in the front and rear windshields, doors, windows, engine compartment, trunk, and other body parts of automobiles to fill the gaps between body parts. They have functions such as shock absorption, waterproofing, dustproofing, sound insulation, and decoration, and play a protective role for drivers, passengers, and the entire vehicle.

[0003] Automotive sealing strips are produced using rubber extrusion equipment. During the extrusion process, the extrusion cylinder needs to be heated to melt the rubber material before it is extruded from the sealing strip mold. Temperature control is crucial in this process. The conventional method involves setting up multiple heating rods around the outside of the extrusion cylinder. However, the temperature varies, with areas without heating rods experiencing lower temperatures. Temperature control is not ideal, and the process is costly, has poor applicability, and cannot meet the needs of actual use.

[0004] Therefore, there is a need for automated processing equipment for automotive sealing strip rubber extrusion molds, which aims to solve the above problems. Utility Model Content

[0028] See Figures 1-3An automatic processing equipment for automotive sealing strip rubber extrusion molds includes a support platform 1, an extrusion cylinder 2 for processing mounted on the support platform 1, a heating cylinder 3 connected to the outside of the extrusion cylinder 2, a feed pipe 4 for feeding material connected to the extrusion cylinder 2, and an extrusion pipe 25 for discharging material on the extrusion cylinder 2. It also includes:

[0029] The extrusion feeding mechanism is installed on the extrusion cylinder 2 and is used for extrusion feeding and uniform feeding at the feed pipe 4.

[0030] Furthermore, the extrusion feeding mechanism includes an extrusion shaft 11 and an extrusion blade 22 for extrusion feeding. The extrusion shaft 11 is rotatably mounted inside the extrusion cylinder 2. The extrusion shaft 11 is provided with the extrusion blade 22. The output shaft of the motor 10 is fixedly connected to the extrusion shaft 11. The motor 10 is fixedly mounted on the support platform 1.

[0031] Furthermore, the extrusion feeding mechanism also includes a stirring flap 24 for uniform feeding into the feed pipe 4. The stirring flap 24 is rotatably connected to the inside of the feed pipe 4 via a stirring shaft 6, and the stirring shaft 6 is rotatably connected to the support frame 5. The support frame 5 is fixedly installed on the feed pipe 4. A first pulley 7 is fixedly connected to the stirring shaft 6, and a second pulley 9 is fixedly connected to the extrusion shaft 11. The first pulley 7 is rotatably connected to the second pulley 9 via a synchronous belt 8.

[0032] Preferably, when performing rubber extrusion processing, the rubber raw material to be extruded is fed into the feed pipe 4, and the output shaft of the motor 10 drives the extrusion blades 22 on the extrusion shaft 11 to rotate, thereby realizing the rubber extrusion processing and material discharge from the extrusion pipe 25.

[0033] In addition, during the extrusion process, the extrusion shaft 11 is driven by the synchronous belt 8 to rotate the stirring flap 24 on the stirring shaft 6, which facilitates the uniform feeding of material into the feed pipe 4 and avoids the blockage of material feeding at the feed pipe 4, thus significantly improving the processing efficiency.

[0034] It should be noted that the motor 10 is driven by an externally connected power supply and controller (not shown in the figure), which is common knowledge known to those skilled in the art and will not be elaborated further in this article.

[0035] Example 2

[0036] like Figures 1-4 As shown, this embodiment, based on embodiment 1, also includes a circulating heating mechanism, which is installed on the heating cylinder 3 and used for circulating heating treatment inside the extrusion cylinder 2.

[0037] Furthermore, the circulating heating mechanism includes a heating rod 21 for heating the inside of the heating cylinder 3. The heating cylinder 3 has a liquid storage chamber 23 for storing heatable liquid. The heating rod 21 is movably connected to the inside of the liquid storage chamber 23 through a mounting ring 19. The mounting ring 19 has a plurality of flow guiding holes 20 for guiding the flow.

[0038] Furthermore, the circulating heating mechanism also includes a push ring 15 for driving the heating rod 21 to reciprocate. The push ring 15 is fixedly connected to the mounting ring 19 via a guide rod 17. A spring 18 is provided at the connection between the push ring 15 and the heating cylinder 3. Several second protrusions 16 are provided on the push ring 15.

[0039] Furthermore, the circulating heating mechanism also includes a pressure ring 13 for driving the push ring 15 to reciprocate. The pressure ring 13 is provided with a plurality of first protrusions 14 that are adapted to and slidably connected to the second protrusions 16. The pressure ring 13 is fixedly connected to the extrusion shaft 11 through the connecting frame 12.

[0040] Furthermore, a temperature display screen 26 for temperature display is provided on the support platform 1, and a support foot 27 for support is provided at the bottom of the support platform 1.

[0041] Preferably, in this embodiment, the liquid storage chamber 23 on the heating cylinder 3 stores liquid for heating (the liquid storage chamber 23 is provided with an exhaust hole for heating exhaust and an inlet pipe for injecting liquid, which are not shown in the figure), and the heating rod 21 heats the liquid in the liquid storage chamber 23, so that the heated liquid surrounds the outside of the extrusion cylinder 2, thereby achieving uniform heating treatment of the extrusion cylinder 2.

[0042] In addition, as the extrusion shaft 11 rotates, it drives the first protrusion 14 on the pressure ring 13 to rotate. Under the adaptive connection between the first protrusion 14 and the second protrusion 16 on the push ring 15, and under the elastic action of the spring 18, the push ring 15 drives the mounting ring 19 on the guide rod 17 to reciprocate within the liquid storage chamber 23. Thus, the mounting ring 19 drives the heating rod 21 to reciprocate within the liquid storage chamber 23, thereby achieving uniform heating treatment at various positions. Moreover, the manufacturing cost is low, making it worthy of widespread use.

[0043] In addition, it also promotes the flow of liquid in the liquid storage chamber 23, thereby further improving the heating efficiency of the extrusion cylinder 2. The heating effect is good, which promotes the extrusion processing of the rubber. The temperature display screen 26 can display the heating temperature in the liquid storage chamber 23 in real time, which is convenient for corresponding adjustment and easy to use.

[0044] It should be noted that both the heating rod 21 and the temperature display screen 26 are driven by an externally connected power supply and controller (not shown in the figure). This is common knowledge known to those skilled in the art, and will not be elaborated further in this article.

[0045] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
