Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an extrusion mold for automotive rubber sealing strips. Background Technology

[0002] Automotive rubber sealing strips are widely used in car doors, windows, body, seats, sunroofs, engine compartments, and trunks, playing an important role in waterproofing, sealing, sound insulation, dustproofing, antifreeze, shock absorption, heat preservation, and energy saving.

[0003] Automotive sealing strips are mainly made of EPDM rubber foam and compacted composite, which has good elasticity, resistance to compression deformation, aging, ozone, chemical action, and a wide operating temperature range (-40℃~+120℃). They contain unique metal clips and tongue-shaped buckles, making them sturdy, durable, and easy to install.

[0004] Patent CN216001361U discloses an extrusion mold for preparing automotive window sealing strips, including an extrusion device, a connecting mold, and multiple extrusion molds. The connecting mold and the extrusion end of the extrusion device are threadedly connected. Two fixing plates are fixedly mounted on the right end of the extrusion device, and two first fixing rods are fixedly mounted between the two fixing plates. Two lead screws are rotatably mounted between the two first fixing rods via a first bearing. A driving mechanism is provided at the upper end of the lead screws. Multiple symmetrically arranged threaded blocks are provided on the rod walls of the two lead screws. A sliding mechanism is provided at one end of the two threaded blocks facing each other, and a sliding rod is provided at the other end of the sliding mechanism. The two sliding rods are fixedly mounted on the extrusion mold at one end facing each other. A second fixing rod is fixedly mounted on the middle right side of the fixing plate, and an electric cylinder is fixedly mounted on the left end of the second fixing rod. This utility model allows for convenient replacement of the extrusion mold, reducing the workload of the workers.

[0005] However, this patented technology still has the following problems: First, the patented technology achieves the replacement of the mold head through the linkage of various motors, reducing the workload of the staff; however, in actual production and use, some rubber will stick to the mold when the sealing strip is extruded, so the mold head needs to be cleaned regularly. However, the mold head of this patented technology is not easy to remove for cleaning. At the same time, the sealing strip needs to be cooled after extrusion in order to quickly set its shape, but this device does not have a corresponding cooling structure, which causes the extruded sealing strip to not cool down quickly, resulting in deformation and a decline in product quality. Utility Model Content

[0006] In view of the above technical problems, this utility model provides an extrusion mold for automotive rubber sealing strips that can improve product quality.

[0007] This utility model provides an extrusion mold for automotive rubber sealing strips, including a worktable.

A cooling water tank is sleeved on the front end of the extrusion die head, and water pipes are connected to the left and right sides of the cooling water tank. One end of each water pipe is connected to the same water storage tank, which is fixed to the front side of the worktable. A water pump is installed in the middle of the water pipe located on one side of the cooling water tank. A telescopic cylinder is fixedly connected to the top rear side of the cooling water tank, and the telescopic cylinder is connected to a fixed plate, which is fixed to the outside of the fixed base.

[0008] The front side of the fixed base is provided with multiple positioning holes, and the outer side of the fixed base is provided with multiple threaded mounting holes.

[0010] The cooling water tank is provided with an outlet pipe at the bottom and a through hole in the middle.

[0011] A water inlet pipe is installed on the top of the water storage tank.

[0012] The beneficial effects of this utility model are as follows: This utility model is an extrusion mold for automotive rubber sealing strips. By setting up a cooling water tank, a water storage tank, and water pipes, the cooling water tank is mounted on the extrusion die head to cool the extrusion die head, thereby cooling the extruded rubber sealing strip and making it better formed for subsequent cutting work; improving work efficiency; by setting an insert plate on the extrusion die head and setting corresponding positioning holes on the fixing seat, the two are inserted and fixed by multiple bolts to achieve a detachable connection of the extrusion die head, which is convenient for future replacement of other dies head, and also convenient for later regular maintenance and cleaning.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0020] As shown in the figure, this utility model provides an extrusion mold for automotive rubber sealing strips, including a workbench 1. The workbench 1 is characterized by having a support seat 2 fixedly connected to the top left and right sides, an extrusion device 3 fixedly connected to the top of the support seat 2, a feed pipe 11 set on the top of the extrusion device 3, a protective box 10 connected to the outside of the feed pipe 11, a fixing seat 4 fixedly installed on the front side of the extrusion device 3, and an extrusion die head 5 detachably connected to the fixing seat 4 by bolts 6. A cooling water tank 7 is sleeved on the front end of the extrusion die head 5, and water pipes 8 are connected to the left and right sides of the cooling water tank 7. One end of each water pipe 8 is connected to the same water storage tank 12, which is fixed to the front side of the workbench 1. A water pump 9 is set in the middle of the water pipe 8 located on one side of the cooling water tank 7, and a telescopic cylinder 14 is fixedly connected to the top of the rear side of the cooling water tank 7.
