Description

Precision casting mold without thimble trace for body of beauty clamp

Technical Field

The utility model relates to a precision casting mold without thimble marks on a body of a pair of beauty pliers.

Background

The beauty clamp is a tool often used by a manicure and manicure master for trimming nails and cutting dead skins, however, the beauty clamp is mostly cast through a precision casting mold, the traditional beauty clamp precision casting mold mostly arranges ejector pins on the side surfaces and the hinged parts of a main clamp body model and an auxiliary clamp body model, the ejector pins are arranged at the two positions and can leave the position trace of the ejector pins after the main clamp body and the auxiliary clamp body are cast, however, the ejector pin trace can be removed by a processing and polishing party when the beauty clamp is processed, so that the defects of multiple procedures of processing the beauty clamp, more labor, high processing cost, slow delivery rate and the like are caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide the precision casting mold without thimble marks for the clamp body of the beauty clamp.

The utility model is realized by the following technical scheme:

according to one technical scheme adopted by the utility model: the utility model discloses a precision casting mold without thimble marks on a body of a pair of beauty pliers, which comprises an upper mold and a lower mold, wherein a material flow channel is arranged on each of the upper mold and the lower mold and is connected with a main pliers body model and an auxiliary pliers body model, casting wax is injected into the material flow channel from the material flow channel to fill the main pliers body model and the auxiliary pliers body model through a sprue model after the upper mold and the lower mold are closed, thimbles are arranged in nail holes of a hinged part of the main pliers body model and the auxiliary pliers body model and on the sprue model, telescopic springs are sleeved on the peripheries of the thimbles, the end parts of the thimbles are in a plane with the inner surfaces of the main pliers body model and the auxiliary pliers body model, the thimbles can be stretched to be in contact with the surfaces of a cast main pliers body and the cast auxiliary pliers body, and the main pliers body and the auxiliary pliers body are supported by the thimbles to be demouldered with the mold after the cast main pliers body and the auxiliary pliers body.

The number of the main forceps body model and the number of the auxiliary forceps body models are respectively set to be 1-20.

By adopting the structure, the thimble is arranged at the pouring gate and the nail hole, and the main clamp body and the auxiliary clamp body after casting, forming and demoulding have no thimble trace, so that the regret that the thimble trace is arranged on the surfaces of the main clamp body and the auxiliary clamp body in the casting and forming process of the traditional cosmetic clamp precision casting mould is effectively solved, the four steps of direct rolling, assembling, opening and splaying are realized, the goods can be delivered, a large amount of time, labor and cost are saved, and the delivery rate is improved.

In addition to the objects, features and advantages described above, other objects, features and advantages of the present invention are also provided. The present invention will be described in further detail below with reference to the drawings.
