Description
Technical field
The utility model relates to a kind of big tapering carbide alloy edge and pieces together mould, belongs to the die cast technical field of mold.
Technical background
The general circular conelet degree of the carbide alloy mould of making is generally whole die, also presses the conelet degree for the big end in die type hole and extends, and its little tapering of the drift of the big end of mould gets final product with addition of the worker by it.Yet for big tapering and profile the mould of some convex tendons is arranged, as still using the unitary mould structure, convex tendon can't moulding, is difficult for processing, and the taper big opening end has major diameter partly to exist, and is undesirable.
Summary of the invention
The utility model purpose is to provide a kind of big tapering carbide alloy edge of being convenient to the big tapering carbide alloy moulding of surface band convex tendon to piece together mould, solved employing overall structure that prior art exists and can't finish the problems such as moulding that big tapering and profile have the carbide alloy of some convex tendons.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises the stop of bottom, core and following coaxial being assemblied in the stop in lower end of dashing, sheath is located at the upper end of described stop, upper cavity die, die cavity and lower cavity die are coaxial from top to bottom to be arranged in the sheath, the type hole of die cavity is tapered, described upper end coaxial cooperation of dashing down is in lower cavity die, the upper punch coaxial cooperation is in upper cavity die, described die cavity inwall is provided with some moulding convex tendons, the moulding convex tendon corresponding position of described upper cavity die and lower cavity die and die cavity inwall is respectively equipped with convex tendon and following convex tendon, rush on described and be provided with the upper groove that cooperates with the last convex tendon of upper cavity die, the described end outer wall that rushes to down is provided with the low groove that cooperates with the following convex tendon of lower cavity die inwall.Wherein, upper cavity die, die cavity and lower cavity die adopt the split setting, can solve the problem at the type hole of big taper die cavity inwall processing convex tendon; On the other hand convex tendon and following convex tendon are being set respectively on upper cavity die and the lower cavity die, and upper groove and the low groove that matches with last convex tendon and following convex tendon is set respectively in upper punch and following rushing to, the problem that occurs convex tendon top bedding and padding in can avoiding suppressing, thereby with the size of formed product to regulation, going up convex tendon and following convex tendon in addition cooperates with upper groove and low groove and has directionality, solved upper punch and upper cavity die and dash down and lower cavity die between orientation problem, be easy to charging, be easy to produce in batches.
As preferably, described sheath endoporus is square, the outline of described upper cavity die, die cavity and lower cavity die be with the sheath endoporus match square.Be easy to the location of upper cavity die, die cavity and lower cavity die on the one hand, guarantee the aligning between upper cavity die, die cavity and the lower cavity die three on the other hand.
As preferably, described core is corresponding to tapered in upper cavity die and the die cavity height.Wherein, core is arranged to the demoulding after taper can be convenient to moulding, easy operating corresponding to the position in upper cavity die and the die cavity height.
As preferably, the height of described stop is greater than the height sum of described upper cavity die and die cavity, and described stop is provided with an opening.Wherein, the height of stop can make stop as spacing dual-purpose with the demoulding greater than the height sum of described upper cavity die and die cavity, and opening is set on stop, and it is convenient to be beneficial to when getting product and opsition dependent.
As preferably, interference fit between described sheath endoporus and upper cavity die, die cavity and the lower cavity die outline can guarantee that the location between sheath and upper cavity die, die cavity and the lower cavity die is reliable.
As preferably, the big end in described die cavity type hole up small end down, thereby reduce work loading height and be easy to charging.
Therefore, the utlity model has the characteristics such as big tapering carbide alloy moulding that to be convenient to surface band convex tendon.
