Abstract
The invention relates to a pushrod mechanism for a metal die-casting die. The pushrod mechanism comprises a support plate, a movable template, a pushrod and a die casting, wherein the movable template is arranged above the support plate; concentric mounting holes are formed in the support plate and the movable template; the pushrod penetrates through the mounting holes, and contacts with the bottom end of the die casting; one side of the pushrod is connected with a plastic guide sleeve layer, and the other side of the pushrod is connected with a forming insert; the forming insert is inserted into a main die core; a plurality of trapezoidal grooves are downwards formed in the plane, contacting with the die casting, of the pushrod; a plurality of radiation holes are formed in the outer cylindrical surface of the pushrod. The pushrod mechanism is simple in structure, convenient to machine and maintain and low in operation failure rate, and pushing-out safety and reliability are achieved; the trapezoidal grooves are formed in the upper surface of the pushrod, so that gas on the contact part is effectively exhausted, and the condition that the die casting cannot be rapidly pushed out because the top end of the pushrod and the bottom end of the die casting are adhered under the action of pressure is avoided; meanwhile, the radiation holes are formed, so that the service life of the pushrod is prolonged, and lubrication effects are improved.
Description
Technical field
The present invention relates to die cast metal forming field, particularly relate to a kind of transfer bar mechanism of metal crimp mold.
Background technology
Die cast metal is shaping is by the molten metal of melting at a higher pressure, at full speed be packed into compression mod die cavity, and molten metal is solidified in a high voltage state and forms the process of metal crimp foundry goods, it is one most effective in current all metal casting forming methods.Along with the development that die cast metal is shaping, the punch forming of die cast metal forming technique and injection-moulding plastic, metallic plate is listed as three large shaping systems.The shaping distinguishing feature of die cast metal is: can forming shape is complicated, wall is thin non-ferrous metal structural member, be a kind of high efficiency, high accuracy, high interchangeability, low consumed precision component forming technique, metal crimp mold realizes die cast by the operation of die casting machine.
After molten metal cooling curing in mold cavity is shaping, due to reasons such as inprocess shrinkage, die casting can pack tightly the surface at forming part to some extent, and the mechanism that die casting is deviate from from mould is called ejecting mechanism.Common ejecting mechanism is by single or multiple release element; with an inferior goods repeatedly projecting motion; the mechanism that die casting can be released; modal version has push rod ejecting mechanism, ejector sleeve ejecting mechanism, stripper ejecting mechanism, rotation stripping mechanism and the comprehensive ejecting mechanism of multicomponent etc.; because transfer bar mechanism is easily manufactured; being convenient to installation, maintenance and replacing, is therefore that the most frequently used one releases form.But at present, push rod, in the process releasing die casting, because die casting and push rod contact position are plane contact, if there is die casting for cool completely, can cause push rod top and die casting bottom to be bonded in one piece due to pressure effect, cannot realize quick release.
Summary of the invention
The present invention, in order to overcome deficiency of the prior art, provides a kind of transfer bar mechanism of metal crimp mold.
The present invention is achieved through the following technical solutions:
A kind of transfer bar mechanism of metal crimp mold, comprise gripper shoe, moving platen, push rod, die casting, described moving platen is arranged on the top of gripper shoe, gripper shoe and moving platen offer concentric installing hole, described push rod passes installing hole and contacts with the bottom of die casting, the side of described push rod is connected with plasticity guide pin bushing layer, and opposite side is connected with shaping insert, and described shaping insert is embedded in main core; The plane contacted with die casting at described push rod offers multiple dovetail groove downwards and offer some louvres on the external cylindrical surface of push rod.
As the preferred technical solution of the present invention, the quantity of described dovetail groove is three, and the distance between adjacent dovetail groove is equal.
As the preferred technical solution of the present invention, described louvre is circular hole, is convenient to processing and manufacturing, and this louvre not only can dispel the heat but also can inject lubricating oil, to reduce the force of sliding friction in pushrod movement process.
As the preferred technical solution of the present invention, described die casting packs tightly the upper surface in main core, and push rod directly promotes die casting and comes off.
Compared with prior art, the invention has the beneficial effects as follows: transfer bar mechanism provided by the invention, structure is simple, be convenient to processing and maintenance, projecting motion is safe and reliable, and running fault not easily occurs; Offer dovetail groove by the upper surface at push rod, effectively discharge the gas of contact position, avoid push rod top and die casting bottom and be bonded in one piece due to pressure effect, quick release cannot be realized; Simultaneously by having offered louvre, improve service life and the lubricant effect of push rod.
