[0002] Automotive foam plays an important role in the automotive industry, and its applications are wide and diverse. Automotive foam materials are mainly used to make automotive parts such as front windshield sponges, fender sponges, and front fender gap plugging sponges. These parts are mainly located in the front area of ​​the car, close to the wipers, driving wheels, front hoods, and gap drainage areas. Automotive foam materials are used to make parts that connect the inside and outside of the car, and their water-proof and water-repellent properties are particularly important.

[0003] The advantages of automotive foam include environmental protection: automotive foam materials are mostly environmentally friendly materials, such as EVA foam and IXPP foam, which meet the environmental protection requirements of the modern automobile manufacturing industry; lightweight: automotive foam materials are lightweight, which helps to reduce the overall weight of the car and improve fuel economy; safety: automotive foam has good shock resistance, cushioning, sound insulation and other properties, which helps to improve the safety and comfort of the car.

[0004] During the production process of automotive foam, its water tightness needs to be tested. Nowadays, when testing automotive foam, two simpler splints are usually used to fix the automotive foam, and the staff usually operate it manually. This leads to uneven clamping force, poor fixing effect of automotive foam, uneven water volume detection, etc. during the test. The operation is more cumbersome and cannot meet production needs. Therefore, a special tooling for automotive foam water tightness testing is proposed to solve the above problems. Utility Model Content

It solves the problem that the automotive foam is usually fixed by two relatively simple plywood, and the staff usually operates it all manually. This leads to problems such as uneven clamping force, poor fixing effect of the automotive foam, uneven water volume detection, etc. during the test, and the operation is cumbersome and cannot meet the production needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special tool for testing the water tightness of automotive foam, comprising a workbench and a support plate fixedly connected to the top of the workbench, a top plate fixedly connected to the side of the support plate away from the workbench, and a fixing structure extending to the top of the workbench to fix the automotive foam is provided inside the workbench;

[0007] The fixing structure includes a bidirectional threaded rod rotatably connected to the inside of the workbench, the external thread of the bidirectional threaded rod is connected to a threaded sleeve, the top of the threaded sleeve is provided with a placement seat extending to the top of the workbench, a connecting block is fixedly connected between the placement seat and the threaded sleeve, and the inside of the placement seat is provided with a transparent clamping plate extending to the top thereof.

[0008] Furthermore, there are two of the placement seats and two of the transparent clamps, and the two transparent clamps are symmetrically distributed on the front and back of the top of the workbench, and the front of the transparent clamp on the back is fixedly connected with a positioning column.

[0009] Furthermore, a partition is fixedly connected inside the workbench, the bidirectional threaded rod passes through and is rotatably connected to the partition, and a rocker for rotating the bidirectional threaded rod is rotatably connected to the front of the workbench.

[0010] Furthermore, a limiting sliding block extending into the interior of the workbench is fixedly connected to the bottom of the placement seat, and a limiting sliding groove matched with the limiting sliding block is provided on the upper surface of the workbench.

[0011] Furthermore, the front surface of the placement seat is threadedly connected to a threaded rod extending into the interior thereof, one end of the threaded rod close to the transparent clamping plate is rotatably connected to a clamping fixing plate, and one end of the threaded rod away from the clamping fixing plate is fixedly connected to a rotating handle.

[0012] Furthermore, a water tank is fixedly installed on the side of the workbench top away from the support plate, a delivery pump is fixedly installed on the inner bottom wall of the water tank, one end of the delivery pump is fixedly connected to a hose extending to the top of the water tank, and one end of the hose away from the delivery pump is fixedly connected to a water injection head.

[0013] Furthermore, a mounting plate is fixedly connected to one side of the top plate close to the workbench, the water injection head is fixedly installed on the bottom of the mounting plate, and the water outlet of the water injection head is aligned between the two transparent clamping plates.

[0014] Compared with the prior art, the utility model provides a special tooling for testing the water tightness of automotive foam, which has the following beneficial effects:

[0015] 1. The special tooling for testing the water tightness of automotive foam drives the two-way threaded rod to rotate by turning the rocker, and then drives the two threaded sleeves and the placement seat to move relative to each other through the two-way threaded rod, so that the two placement seats can respectively drive the two transparent splints to move relative to each other, and then set the positioning column to facilitate the staff to place the automotive foam on the transparent splint, and at the same time form a U shape, so as to facilitate the clamping and fixing of the automotive foam.

[0016] 2. The special tooling for testing the water tightness of automotive foam can deliver the test liquid to the inside of the hose by setting a delivery pump and a water storage tank, and then output it through the water injection head, so that the test liquid can be accurately injected into the automotive foam to start the test process. This solves the problem of usually fixing the automotive foam with two relatively simple plywood, and the staff usually operate it manually. This leads to uneven clamping force during the test, poor fixing effect of the automotive foam, uneven test water volume, etc. The operation is more cumbersome and cannot meet the production needs.
