Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a precision clamper for a micro mold. Background Art

[0002] With the continuous development of micro-manufacturing technology, micro-molds are increasingly used in micro-electromechanical systems, microelectronic packaging, biomedicine and other fields. Micro-molds require clamping devices during processing. Existing clamping devices for molds have complex structures and relatively simple performance. In actual processing, they are usually only convenient for clamping molds of specific specifications, which is not easy to adjust and use.

[0003] A Chinese patent discloses a clamping device for a plastic mold (authorization announcement number CN209304392U). The limit plate in the patented technology can move along the slide rail under the push of an electric telescopic rod. When it moves to a suitable distance, a long rod can be inserted into a circular hole through a through hole to fix the limit plate. The lifting and retracting mechanism on one side of the baffle can better clamp the mold.

[0004] However, it has certain disadvantages: the clamping force of the mold cannot be precisely controlled, and it is easy to cause damage to the mold surface due to excessive clamping force, and it is also easy to cause the mold to be loosely fixed due to insufficient clamping force. Utility Model Content

[0005] The purpose of the utility model is to provide a precision clamp for a micro mold to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] As a further solution of the utility model: the detection mechanism includes a connecting seat, a seat cover is installed on the left end of the connecting seat, and a first connecting plate is slidably connected to the inside of the connecting seat, a connecting rod is installed through the inside of the first connecting plate, a second connecting plate is installed on the right end of the connecting rod, an elastic pad is installed on the right surface of the second connecting plate, and a spring is installed on the left surface of the first connecting plate.

[0009] As a further solution of the utility model: the lower end of the slide plate is slidably connected to the inside of the slide groove.

[0010] As a further solution of the utility model: the right end of the mounting bolt is threadedly connected to the inside of the slide plate.

[0011] As a further solution of the utility model: the seat cover is installed on the right side surface of the skateboard, the connecting rod movably passes through the right side surface of the connecting seat and the seat cover, and the connecting rod movably passes through the skateboard, and the left end of the connecting rod movably fits the pressure sensor.

[0012] As a further solution of the utility model: the left end of the spring is installed on the right side surface of the seat cover.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model drives the slide plate to move to one side close to the micro mold by rotating the rocker, and the elastic pad in the detection mechanism fits the micro mold. The elastic pad is squeezed to produce relative displacement, and fits the pressure sensor through the connecting rod and squeezes the pressure sensor. When the pressure sensor detects that the pressure is within the set range, the external control system sends an alarm, and the staff stops rotating the rocker. The detection mechanism ensures precise clamping, and the fixing pressure on the micro mold will not be too large or too small, thereby avoiding damage to the surface of the micro mold caused by excessive pressure, and also avoiding the micro mold being unable to be firmly fixed due to insufficient pressure.
