Description

Technical Field

[0001] The utility model belongs to the technical field of ignition coil sheath processing, and particularly relates to a high-voltage sheath processing and fixing mechanism for an ignition coil. Background Art

[0002] As automotive gasoline engines evolve toward higher speeds, higher compression ratios, higher power, lower fuel consumption, and lower emissions, traditional ignition systems are no longer suitable. The core components of an ignition system are the ignition coil and the switch. Increasing the energy of the ignition coil allows the spark plug to produce a sufficiently energetic spark, a fundamental requirement for the ignition system to adapt to modern engine operation. To protect the ignition coil from damage, a protective sheath is typically added to the exterior of the system. This sheath is typically manufactured using injection molding.

[0003] Publication No. CN104960152A discloses a method for producing a silicone ignition coil cover and its molding equipment. In this patent, the upper and lower molds are closed and then injection molded to achieve the production and processing of the ignition coil cover. However, it does not disclose how the upper and lower molds are fixed to the mold base. Although the currently conventional bolts can also play a fixing role, they are relatively inconvenient during disassembly and assembly. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The purpose of the utility model is to provide a high-voltage sheath processing and fixing mechanism for an ignition coil, so as to solve the problem of complicated operation of the structure used in the prior art for fixing the upper and lower molds.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a processing and fixing mechanism for a high-voltage sheath of an ignition coil, comprising a mold base one, the middle part of which is through-shaped, and a cavity is reserved on its bottom end surface; a mold base two, which is placed at the bottom of the mold base one, and a non-through slot is opened in the middle part, and the slot is completely connected with the through-hole of the mold base one, and can hold the upper and lower molds, and a cavity identical to that of the mold base one is provided on its top surface; a limiting assembly, which is composed of an adjusting part and a mounting part, wherein the adjusting part is placed in the cavity of the mold base one and the mold base two, and one end of the mounting part is connected to the adjusting part, and the other end passes through the outside of the cavity. When installing the upper and lower molds, the mounting part is pushed outward by the adjusting part, and the mounting part is stuck into the inside of the side of the upper and lower molds, thereby realizing the limited installation.

[0006] Preferably, the adjusting part is an airbag tube, which has at least one air supply and outlet end, which is connected to an external air supply device. The air supply device includes an air pump installed on the side of mold base one and mold base two, and the mounting part is a limit block arranged around the four walls of the slot. During the installation of the upper and lower molds, the gas is transmitted to the airbag tube through the external air supply device. After the airbag tube bulges, it will push out the limit block, and the limit block will be stuck in the side hole of the upper and lower molds to achieve rapid fixation.

[0007] Preferably, one end of the limit block is also adhered with double-sided tape, and the double-sided tape is adhered to the inner side of the airbag tube to achieve the connection between the two. When the airbag tube is supplied with air, the limit block is pushed out synchronously. Conversely, when the airbag tube is deflated, the limit block will be synchronously driven to retract and separate from the upper and lower molds.

[0008] Preferably, the cavities on mold base one and mold base two include placement grooves symmetrically opened on opposite surfaces of the two, and the airbag tube is placed in the placement groove; the inner wall of the placement groove toward the middle position of mold base two is provided with a through groove for the limit block to pass through, so that the limit block can pass through to complete subsequent tightening, or retract to complete separation.

[0009] Preferably, the cavity also includes a through hole opened on the end surface of mold base one and mold base two, which is connected to the placement groove. The airbag tube is placed in the through hole and passes through to the outside of mold base one and mold base two, so as to facilitate the connection of the airbag tube with external air supply equipment.

[0010] Preferably, the cross-sectional areas of the mold base 1 and the mold base 2 are equal, and the mold base 1 and the mold base 2 are fixed by bolts.

[0011] Preferably, an upper die or a lower die is placed in the die base one and the die base two, and the sides of the upper die and the lower die are provided with holes or annular grooves for the limit blocks to be inserted into.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Through the design of the utility model, the upper and lower molds and the mold base can be quickly fixed. When facing different processing requirements, the upper and lower molds with different specifications and sizes can be quickly disassembled and fixed. The overall flexibility and versatility are greatly improved, and the shortcomings of the existing fixed structure are improved. BRIEF DESCRIPTION OF THE DRAWINGS
