Description
Technical field
The present invention relates to casting technology field, particularly relate to a kind of squeeze casting mould.
Background technology
Aluminium alloy because its density is little, intensity is high, shape and the advantage such as good processability, recoverable,
It is widely used in the fields such as Aero-Space, military project, automobile, building.Owing to machining reduces material
Material utilization rate, increases production cost, so increasing alloy product tends to straight forming.
Connecting rod is the major part of transmitting movement and power, and its manufacturing process can be summarized as casting and die forging two kinds
Technique.Extrusion casint is also called liquid forging, is the few nothing of one grown up based on casting and forging
The novel metal processing technique extrusion casint of machining is the near-net-shape technique of a kind of advanced person, melted
Molten metal under high pressure solidifies and plastic deformation, cast structure is fine and close, mechanical property close to forging level,
The foundry goods that a lot of mechanical property requirements are high selects squeeze cast form.But, extrusion casint is due to metal
Liquid waters fluence to be difficult to control, and is commonly present that casting dimension is uneven or misrun, easily in forming process
Shrinkage porosite and crackle occur.
Summary of the invention
In order to overcome above-mentioned problem of the prior art, the invention provides a kind of squeeze casting mould, should
Mould structure is simple, production cost is low, it is possible to reduce impact and the generation of eddy current during casting and pouring, with
And the defect such as shrinkage cavity and porosity, so that link member even tissue is fine and closely woven.
Solve the technical problem that required by the present invention and can be achieved through the following technical solutions:
A kind of squeeze casting mould, including upper clamping plate, lower mold seat board, lower mold seat board passes through pull bar with upper
Die holder plate is connected, and the top of lower mold seat board is separately installed with low mold frame, upper framed, has lower mold, lower mold
Major part core, lower mold microcephaly's core are arranged in low mold frame, have upper mold, spreader, upper mold core to pacify
It is contained in framed interior；Described framed be arranged over upper molded plate, have punch one end through upper molded plate,
Upper framed and described upper mold is connected, and the described punch other end is fixed on punch retainer.
Further, described punch retainer is arranged above punch pad.
Further, described upper molded plate framed is connected by alignment pin is fixing with upper.
Further, described punch is provided with spring.
Further, between described framed and low mold frame, guide pillar is installed, described guide pillar is provided with and leads
Set.
Further, pressure head is installed between described low mold frame and lower mold seat board, described pressure head is provided with
Gland.
Beneficial effects of the present invention: a kind of squeeze casting mould, this mould structure is simple, production cost
Low, it is possible to reduce impact and the defect such as the generation of eddy current and shrinkage cavity and porosity, institute during casting and pouring
The defects such as the connecting rod cast structure densification that obtains, pore-free, and dimensional accuracy is high.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be readily apparent from effect
Understand, below in conjunction with being specifically illustrating, the present invention is expanded on further.
When being embodied as, in conjunction with Fig. 1, a kind of squeeze casting mould, lower mold seat board 1, low mold frame 2,
Upper the most framed 3, upper molded plate 4, upper mold 5, spring 6, punch 7, punch retainer 8, punch pad
9, upper clamping plate 10, spreader 11, upper mold core 12, alignment pin 13, guide pin bushing 14, guide pillar 15,
Lower mold microcephaly's core 16, pressure head 17, gland 18, liquid forging 19, lower mold major part core 20, lower mold
21, pull bar 22.
Squeeze casting mould, including upper clamping plate 10, lower mold seat board 1, lower mold seat board 1 passes through pull bar
22 are connected with upper clamping plate 10, the top of lower mold seat board 1 be separately installed with low mold frame 2, upper framed 3,
Have lower mold 21, lower mold major part core 20, lower mold microcephaly's core 16 to be arranged in low mold frame 2, have on
In mould 5, spreader 11, upper mold core 12 are arranged on framed 3；Upper framed 3 are arranged over upper mold
Pressing plate 4, has punch 7 one end through upper molded plate 4, upper framed 3 is connected with upper mold 5, liquid forging
In 19 cavitys being placed on punch 7 and upper mold 5, punch 7 other end is fixed on punch retainer 8,
Punch retainer 8 is arranged above punch pad 9.Upper molded plate 4 passes through alignment pin with upper framed 3
13 fixing connections.Spring 6 is installed on punch 7.Above between framed 3 and low mold frame 2, guide pillar is installed
15, guide pillar is provided with guide pin bushing 14.Pressure head 17, pressure head are installed between low mold frame 2 and lower mold seat board 1
On gland 18 is installed.
In work process, gravying with meat or vegetables poured over rice or noodles and be set on the lower section of mould, this mould needs three independent hydraulic pressure
Cylinder operation work.During production, aluminium alloy is quantitatively poured in gland, then decline upper mold and move downward
And matched moulds, punch is positioned by spring and auxiliary hydraulic cylinder, and reserves the height of secondary extrusion.
Then hydraulic cylinder works under hydraulic press, the pressure head being connected with lower hydraulic cylinder, with certain speed motion, makes
Aluminium alloy enters die cavity by running gate system, and after filling type and completing, auxiliary hydraulic cylinder drives punch downward
Motion, carries out secondary extrusion to not solidified liquid metal.After product solidification, upper mold rises die sinking,
Auxiliary hydraulic cylinder is the most up, and after rising to certain distance, auxiliary hydraulic cylinder declines, and punch is with upper
Mould does relative motion, and outside liquid forging is by punch launch mode, takes out liquid forging.
