CN-121973122-A - Double-acting holding mechanism

Abstract

Embodiments of the present invention provide a die holder for use in a tool. The die holder may include a nose, a release button, and a die pin. The handpiece includes a mold cavity and a pair of sides on opposite sides of the mold cavity. The release button may extend through a release button aperture formed in the handpiece and include opposite ends extending beyond each of the corresponding pair of sides. The mold pin extends through a mold pin cavity intersecting the release button hole. The mold release button may be actuatable from either of the opposite ends to withdraw the mold pin from the mold cavity.

Claims (10)

1. 1. A die holder for use with a die in a tool, the die holder comprising: A handpiece including a mold engaging surface defining a mold cavity, a pair of lateral surfaces on opposite sides of the mold cavity, a release button aperture, and a mold pin cavity intersecting the release button aperture; A release button extending through the release button aperture, the release button including a pair of opposing ends, each of the opposing ends extending beyond one of the pair of lateral surfaces, the release button including a slot extending between a first slot end and a second slot end, the second slot end defining a recess having at least one sloped surface, and A mold pin extending through the mold pin cavity, the mold pin including a button engagement portion configured to move along at least one sloped surface of the release button and a mold engagement portion extending beyond the mold engagement surface of the nose into the mold cavity to retain the mold.
2. 2. The die holder of claim 1, wherein the die pin extends through the slot of the release button such that the button engagement portion extends beyond the first slot end and the die engagement portion extends beyond the second slot end.
3. 3. The mold holder of claim 1, wherein the nose defines a second mold pin cavity, and Wherein a second mold pin extends through the second mold pin cavity and into the mold cavity to retain the mold.
4. 4. The mold holder of claim 3, wherein the second mold pin is a stop member having a stop ball extending partially into the mold cavity.
5. 5. The mold holder of claim 1, wherein the release button is a first release button, and further comprising a second release button extending through the handpiece and beyond each of a pair of lateral surfaces of the handpiece.
6. 6. The mold holder of claim 5, further comprising a first bridge member coupled to each of the first and second release buttons adjacent one of the pair of lateral surfaces and a second bridge member coupled to each of the first and second release buttons adjacent the other of the pair of lateral surfaces, Wherein each of the first bridge element and the second bridge element is configured to receive an actuation force to release the mold from the mold cavity of the handpiece.
7. 7. The mold holder of claim 1, wherein the release button is double-acting and is actuatable from either of a pair of opposing ends of the release button to withdraw the mold engaging portion from the mold cavity.
8. 8. The mold holder of claim 1, wherein the recess comprises a symmetrical profile.
9. 9. The mold holder of claim 8, wherein the at least one sloped surface slopes away from the mold cavity and is sized to withdraw the mold engaging portion from the mold cavity as the button engaging portion moves in the axial direction of the release button toward one side of the symmetrical profile.
10. 10. The mold holder of claim 1, further comprising a biasing element configured to engage the mold pin proximate the button engagement portion and bias the mold pin toward a retaining orientation.

Description

Double-acting holding mechanism The application is a divisional application of patent application with the application date of 2021, 11/8, the application number of 202180087206.0, the international application number of PCT/US2021/058456 and the application name of 'double-acting holding mechanism'. Cross Reference to Related Applications The present application claims priority from U.S. provisional patent application No. 63/110,492, filed on even 6 months of 11 in 2020, U.S. provisional patent application No. 63/124,985, filed on even 14 months of 12 in 2020, and U.S. provisional patent application No. 63/209,688, filed on even 11 months of 2021, the entire contents of which are incorporated herein by reference. Background The crimper and cutter typically include a crimping or cutting head and certain crimping and cutting features, depending on the particular configuration of the tool. Some crimpers and cutters are hydraulic power tools that include a piston that can apply a force to a crimp head, which can be used to move a crimp feature to perform a crimping or hold down operation at a target crimp location. Some crimpers and cutters may include a die that may be secured to the crimp head via a die retention mechanism. Disclosure of Invention Embodiments of the present invention provide a die holder for use in a tool. The mold holder includes a head including a mold-engaging surface defining a mold cavity and a pair of sides on opposite sides of the mold cavity. The die holder includes a release button that extends through a release button aperture formed in the handpiece. The release button includes a pair of opposing ends extending beyond each of the corresponding pair of sides and a slot extending through the release button. The slot has a first end defining a recess, and the recess has one or more sloped surfaces. The mold retainer includes a mold pin extending through a mold pin cavity formed in the mold engagement surface and intersecting the release button aperture. The mold pin includes a button engagement portion configured to move along the inclined surface and a mold engagement portion sized to extend beyond the mold engagement surface into the mold cavity to engage the mold. In some embodiments, a dual action release assembly for use in a mold is provided. The dual action release assembly includes a mold release button. The mold release button includes a button body having opposite ends each configured to receive an actuation force and a slot extending through the button body. The slot includes a first end and a second end defining a recess having opposed ramped surfaces. The dual action release assembly includes a mold pin having a button engagement portion and a mold engagement portion. The mold pin may be inserted into the recess via the button engagement portion and may be rotated relative to the mold release button between a locked orientation and an unlocked orientation.
