Description
Technical field
The utility model belongs to hardware spare and accessory parts technical field, is exactly specifically a kind of flat surface side of cold extrusion shaped plunger latch head
The master mold mold insert structure of hole forming.
Background technology
Usually using to various hardwares are as processing and install in security protection industry, such as plunger latch head is exactly a kind of common
Hardware.Lock is a kind of device for being commonly used to fasten door or window, and each built-in lock has a plunger latch head, and it can stretch
To be inserted into the metallic plate on doorframe, prevent that door is opened.And plunger latch head is flexible, controlled by a cam.In lock
There is the small pin of a row cylinder the inside, and when inserting the key of this lock, groove on the key will be mutually aligned pin,
It is set to arrange straight line.So, key just can freely carry out back rotation, and be moved by cam driven lock bolt, lock open or
Lock.So plunger latch head usually is designed into profile of one group of circular arc opposite side plus one group of straight opposite side, inner hollow, one and half envelopes
Close, one end is opened wide completely, and flat opposite side carries side opening, semiclosed end center pinking.Wherein, circular arc opposite side face is used to support and locked
Fasten the telescopic slide of head with a bolt or latch, flat opposite side face is then supporting surface during for fastening, and larger contact surface can reduce face pressure by force, greatly
The service life of metallic plate on big increase doorframe.
But, such lock bolt header structure is in cold-heading molding, and the side opening on flat opposite side face becomes very big problem,
Conventional machining process be cold-heading after a set of diel is individually opened to be molded side opening.It is so no doubt feasible, but frequently remove
Operating moves the waste for also bringing the risk of batch mixing and largely carrying, and output efficiency is also reduced.
Utility model content
The purpose of this utility model needs separately vertical station, the technology of one-shot shaping aiming at the flat surface side hole of existing plunger latch head
Defect directly can pass through multistation there is provided a kind of master mold mold insert structure of the cold extrusion shaped flat surface side hole forming of plunger latch head
Fitting cold extrusion shaping machine completes the processing in the flat surface side hole of plunger latch head, substitutes traditional punching technology, improves production efficiency and production
Quality stability, reduces the waste of carrying, has saved production cost.
Technical scheme
In order to realize above-mentioned technical purpose, the flat surface side hole forming of cold extrusion shaped plunger latch head of the utility model design
Master mold mold insert structure, it is characterised in that：It includes master mold core rod body, and the master mold core rod body includes core rod shell, push piece
Pipe can be slidably reciprocated in the mounting hole of core rod shell, and stroke, rear cushion block are limited by rear cushion block in push piece pipe sliding process
In core rod shell, guard aperture plug can be promoted in core rod shell by push piece pipe, and guard aperture plug is provided with chip removal neck,
Head part bar is provided with cushion block afterwards, head part bar can promote push piece pipe, and the core rod shell of guard aperture plug side is built with side core-pulling
Rod, the both sides of side core-pulling rod, which are respectively arranged with transmission wedge and movable wedge, side core-pulling rod, is provided with inclined-plane one and oblique
Face two is corresponding with transmission wedge and movable wedge respectively, and transmission wedge and movable wedge can in core rod shell
Slide, movable wedge is connected with movable spring, transmission wedge can be limited pin limitation stroke in sliding.
The spacer pin is driven on wedge and half groove mounted in half groove of core rod shell and transmission wedge boundary
Corresponding position is provided with stroke groove.
Beneficial effect
The utility model provides a kind of master mold mold insert structure of the cold extrusion shaped flat surface side hole forming of plunger latch head, Neng Gouzhi
The processing that multistation fitting cold extrusion shaping machine completes the flat surface side hole of plunger latch head was connected, traditional punching technology is substituted, greatly improves
Production efficiency and product quality stability, reduce the waste of carrying, have saved production cost.
