Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection, in particular to an air tightness detection device for mold inserts. Background Art

[0002] In-mold inserts are a common method of injection molding. The principle is to implant inserts such as screws and nuts into the mold cavity in advance, and then use an injection molding machine to heat and pressurize the molten plastic material through a plasticizer to make it flow through the needle eye into the mold cavity, then cool and solidify into shape, and finally remove the product from the mold.

[0003] Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Electric vehicles are usually referred to as vehicles that use batteries as energy sources and use controllers, motors and other components to convert electrical energy into mechanical energy to control the current size and change speed. Electric vehicles need to have a dashboard installed above the handlebars to display information such as the battery level, speed, and mileage of the electric vehicle.

[0004] Since the dashboard is connected with electronic components and wires, the waterproof performance of the dashboard is tested, especially the waterproof performance of the screw holes of the dashboard and its base. If the sealing is not good, rainwater will penetrate into the dashboard, causing the electronic components in the dashboard to malfunction and fail to reach the waterproof level. Therefore, electric vehicle dashboards and their bases are basically produced through the in-mold insert process.

[0005] The in-mold insert process is also widely used in the production of notebook shells.

[0006] In order to ensure the sealing of the in-mold inserts, there are many electric vehicle air tightness detection devices for the instrument panel and the screw holes of the base in the prior art, but most of these are electronic detection instruments, which are very automated in operation but very inefficient in use. Summary of the invention

[0007] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a more efficient in-mold insert air tightness detection device.

[0008] In order to achieve the above functions, the technical solution adopted by the utility model is as follows:

[0009] The invention discloses an air tightness detection device for mold-insert parts, comprising a base plate, a detection block arranged on the base plate, the interior of the detection block being a hollow structure, an air inlet hole, an air outlet hole and an air tightness detection hole being arranged on the surface of the detection block, a pressure clamp being mounted on the base plate through a base, a pressure head being arranged on the pressure clamp and placed directly above the air tightness detection hole, and a pressure gauge being mounted on the air outlet hole.

[0010] Preferably, a first sealing ring is provided at the connection between the detection block and the base plate, and a second sealing ring is provided in the airtightness detection hole.

[0011] Preferably, a boss is provided on the pressure head.

[0012] The utility model mold insert air tightness detection device fixes the product to be detected on the detection block through the pressure clamp and the pressure head, uses the existing gas source in the factory to fill in from the air inlet, maintains the pressure for a few seconds, and manually observes the pressure gauge pointer to determine whether it is sealed. The utility model air tightness detection hole can be designed in multiples according to the product, and the efficiency is very high. BRIEF DESCRIPTION OF THE DRAWINGS

They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention. DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1-5 As shown, the in-mold insert air tightness detection device includes a base plate 1, a detection block 2 is arranged on the base plate 1, the interior of the detection block 2 is a hollow structure, and an air inlet hole 3, an air outlet hole 4 and an air tightness detection hole 5 are arranged on the surface of the detection block 2. A pressure clamp 6 is installed on the base plate 1 through a base 7, a pressure head 8 is arranged on the pressure clamp 6 and placed directly above the air tightness detection hole 5, and a pressure gauge 9 is installed on the air outlet hole 4.

[0021] Preferably, a first sealing ring is provided at the connection between the detection block 2 and the base plate 1 , and a second sealing ring is provided in the airtightness detection hole 5 .

[0022] Preferably, a boss is provided on the pressure head 8 .

[0023] The utility model mold insert air tightness detection device is mainly used for the air tightness detection of the mold insert of injection molding. When in use, the product to be detected 100 (such as Figure 5 The airtightness detection hole 5 on the upper part of the detection block 2 should correspond to the insert position of the product 100 to be detected one by one. The pressure head 8 connected to the detection block 2 is driven by the pressure clamp 6 to fix the product 100 to be detected. The air source inside the factory is connected to the air inlet 3 and is closed after inflating for a few seconds. The operator visually observes the pointer of the pressure gauge 9. If there is no fluctuation after a few seconds, it can be determined that there is no leakage. If the pointer of the pressure gauge 9 fluctuates, it is retested or determined to be a defective product. The air inlet 3 is deflated to complete the detection. The device is provided with a first sealing ring and a second sealing ring. Its main function is to ensure the sealing of the device itself. The device is provided with a boss on the pressure head 8. The purpose is to prevent the pressure head 8 from completely contacting the position to be detected after being pressed, so as to expose all the risks of air leakage in the position to be detected.

[0024] The air tightness detection hole 5 of the in-mold insert air tightness detection device of the utility model can be multiple, and the air tightness of multiple in-mold insert positions can be detected at one time. The device itself does not contain electronic parts, and the detection efficiency is very high.

[0025] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
