Press-forming mould of loudspeaker elastic wave

Abstract

The invention provides a press-forming mould of a loudspeaker elastic wave, comprising an upper mould component and a lower mould component. The lower mould component comprises a lower mould head, a movable press sleeve, return springs and a lower template, wherein the lower mould head comprises a moulding body and a bearing column; the moulding body comprises a lower moulding surface and a lower press ring; the movable press sleeve is sleeved on the moulding body and the bearing column; the return springs are sleeved on the bearing column and positioned between the movable press sleeve and the lower template; and the upper mould head and the lower mould head are coaxial. The movable press sleeve and the return springs are added to the lower mould head so that, in the operation of pressing an elastic wave, the upper press ring and the movable press sleeve first press cloth blanks to be moulded tight and ensure that peripheral cloth receives even force; and then the cloth blanks are deeply drawn and pressed to form a finished product so that the folds of the peripheral parts of the finished product of elastic wave can be eliminated. The press-forming mould of the invention can be operated by only one person; and moreover, the finished product can be automatically demoulded, which provides safe, convenient and labor-saving operation.

Description

Technical field: [0001] The invention relates to a mold, in particular to a loudspeaker elastic wave forming pressing mold. Background technique: [0002] The loudspeaker is also called the horn. It is a mechanical device that converts electrical signals into sound vibrations. To play the sound, the loudspeaker must include the speaker unit and the sound, which is the so-called speaker system. The existing speaker system The technology is very mature, but the sound quality of the speaker is an important factor to be considered in the design of the speaker. The sound quality of the speaker will be affected by the sound quality of the speaker, the voice coil, the drum paper and the adhesive. The elastic wave on the speaker is generally formed by stretching and heating the fiber cloth with rubber, such as cotton yarn, hemp yarn, nylon and other elastic materials. The elastic wave is installed between the speaker body and the voice coil to connect and support The role of the vo...

Problems solved by technology

In the pressing process, the bottom of the blank holder 93 around the elastic wave and the bottom of the waist body 92 are prone to wrinkles, and the greater the drop height of the elastic wave's waist body, the greater the possibility of wrinkles, and the more serious the wrinkles. It is the main process of producing waste or defective products in the current elastic wave production process. If such defects occur, when the elastic wave is assembled and glued on the speaker, the connection between the elastic wave and the voice coil will not be tight, resulting in the elastic wave not vibrating normally, thus Affects the sound quality and appearance of speakers

At the same time, in the process of suppressing the elastic wave of the existing elastic wave forming and pressing mold, two people must cooperate to operate. If the cooperation is not good, it is easy to cause work-related accidents, which will bring great damage and loss to the operator and the enterprise.
