Injection mould for curved needle clamp

Abstract

The invention provides an injection mould for a curved needle clamp. The injection mould for the curved needle clamp comprises a fixed mold and a movable mold, wherein the fixed mold is covered and compacted by the movable mold; a parting surface is formed in the combined part of the fixed mold and the movable mold; a mold core, a cavity and a pouring channel are formed in the fixed mold, wherein the bottom part of the cavity is formed at the top part of the mold core; the pouring channel is communicated with the cavity; the injection mould for the curved needle clamp comprises a first hole channel, a second hole channel and a mold picking block, wherein the first hole channel is horizontally formed in the fixed mold and communicated with the cavity; the second hole channel vertically passes through the parting surface and is communicated with the cavity; a drawing pin and an inserting pin are arranged and can be inserted into the first hole channel and the second hole channel; a horizontal through hole is formed at the lower part of the fixed mold; the mold picking block passes through the horizontal through hole and is connected to the bottom part of the mold core; and the pouring channel is provided with a rod-shaped pouring port which is provided with a circular cross section.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold specially used for producing a looper clip. Background technique [0002] In some existing injection molds used for injection molding of looper clips, it is often impossible to meet the injection molding needs of looper clips due to the cavity design, especially for the through holes and positioning holes involved in the present invention. The injection molding requirements for the shape of the cavity and the looper clip of the bump generally cannot be met. In addition, in terms of the design of the runner, the traditional injection mold will affect the production efficiency because of the low flow rate of the wax liquid due to the design of the runner. In the design of the module, due to some defects in the design, such as the inconvenient operation of taking the module, the demoulding operation is troublesome, and it is easy to cause the demoulding failure, resulting in th...

Problems solved by technology

[0002]In some existing injection molds for injection molding of looper clips, the cavity design cannot meet the injection molding needs of looper clips. Especially for the injection molding needs of the shape of the looper clip with through holes, positioning cavities and projections involved in the present invention, generally can not meet. Due to some defects in the design of the module, such as the inconvenient operation of taking the module, the demoulding operation is troublesome, and it is easy to cause demoulding failure, resulting in defective products. The production of looper clips affects production efficiency and increases the cost burden
