Abstract
The utility model discloses a die-casting is with cooling runner device, including runner cover body and cooling ring, runner cover body includes a runner pullover and a runner sleeve who connects the runner pullover, and the cooling ring connects on runner sleeve through hot equipment is supporting, corresponds on cooling ring and runner sleeve and sets up a locating hole, sets up inlet opening and apopore on the cooling ring of locating hole below, forms the connection with the spiral chamber that sets up on runner sleeve outer wall, and the cooling ring internal diameter is less than runner sleeve external diameter by 0.4 ~ 0.5 mm. The utility model takes the sprue bush body as a reference, positions by the positioning hole, and sleeves the cooling ring on the sprue bush body, thereby ensuring the concentricity; the hot assembly does not need welding, the assembly speed is high, the spiral cavity is arranged on the sprue bushing, and the cooling effect is more ideal.
Description
Technical Field
The utility model relates to a die-casting equipment especially relates to a die-casting is with cooling runner device.
Background
The sprue bush belongs to a vulnerable part in the field of die casting molds, and has long manufacturing period and high cost. In the prior art, the sprue bush body and the cooling ring are welded together, argon arc welding is adopted for welding, the precision of the sprue bush body is affected, the local thermal stress of the sprue bush body is increased after welding, the material structure is changed, the thermal fatigue of the sprue bush body accelerates the failure time, and the cooling ring is not easy to damage. Therefore, the cooling ring is welded with the sprue bush body, so that resource waste is caused due to poor recycling; in addition, after the sprue bush is produced for 5000 moulds, tempering and stress relieving treatment are needed through heat treatment, water leakage at the welding position of the sprue bush body and the cooling ring is easily caused in the process, the welding water leakage position needs to be dug and welded again after stress relieving, and the process is complex, the production cost is high, and the production period is long.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the prior art, the utility model aims to provide a cooling sprue device for die-casting.
In order to achieve the above purpose, the utility model adopts the following technical means: the utility model provides a die-casting is with cooling runner device, includes runner cover body and cooling ring, runner cover body includes a runner pullover and a runner cover pipe of connecting the runner pullover, and the cooling ring connects on runner cover pipe through hot equipment is supporting, corresponds on cooling ring and runner cover pipe and sets up a locating hole, sets up inlet opening and apopore on the cooling ring of locating hole below, forms the connection with the spiral chamber that sets up on runner cover pipe outer wall, and the cooling ring internal diameter is less than runner cover pipe external diameter by 0.4 ~ 0.5 mm.
Furthermore, a bayonet is arranged on the outer circumference of the sprue bushing head.
Furthermore, a sink groove is formed in the end face of the sprue bush inwards.
The beneficial effects of the utility model reside in that: the sprue bush body is used as a reference, the positioning hole is used for positioning, and the cooling ring is sleeved on the sprue bush body, so that the concentricity is guaranteed; the hot assembly does not need welding, the assembly speed is high, the spiral cavity is arranged on the sprue bushing, and the cooling effect is more ideal.
Drawings
The following description of the present invention will be made in conjunction with the accompanying drawings and examples.
Fig. 1 is a schematic structural section view of the present invention.
In the figure: 1. the sprue bush comprises a sprue bush body, 11, a sprue bush head, 12, a sprue bushing, 13, bayonets, 14, sink grooves, 2, a cooling ring, 21, positioning holes, 22, water inlet holes, 23 and water outlet holes.
Detailed Description
Example 1
As shown in fig. 1, a cooling sprue device for die casting includes a sprue bush body 1 and a cooling ring 2, where the sprue bush body 1 includes a sprue bush head 11 and a sprue bush 12 connected to the sprue bush head, the cooling ring 2 is connected to the sprue bush 12 through a shrink fit, a positioning hole 21 is correspondingly disposed on the cooling ring 2 and the sprue bush 12, a water inlet hole 22 and a water outlet hole 23 are disposed on the cooling ring below the positioning hole 21 and connected to a spiral cavity disposed on an outer wall of the sprue bush 12, and an inner diameter of the cooling ring 2 is 0.4-0.5 mm smaller than an outer diameter of the sprue bush 12.
The cooling sprue device for die casting is designed into two parts, namely a sprue bush body 1 and a cooling ring 2, the two parts are sleeved by adopting hot assembly, the cooling ring is heated to 800 ℃, and then the cooling ring is assembled on the sprue bush body, and in order to ensure the effect of hot assembly, the size of the inner diameter of the cooling ring and the outer diameter of a sprue bush pipe needs to be limited within a reasonable range. And, with the locating hole location, the hot assembly need not the welding, the assembly is firm, sets up the spiral chamber on runner sleeve 12 outer wall, can not leak.
Example 2
As a specific design of the structure of embodiment 1, a bayonet 13 is provided on the outer circumference of the sprue bush 11.
The end surface of the sprue bush head 11 is provided with a sunken groove 14 inwards.
The sprue bushing head is used for assembling and machining, so that the assembled cooling ring and the sprue bushing cannot be moved to the assembling or machining, and the assembling effect is further ensured.
In conclusion, the utility model takes the sprue bush body as the reference, the positioning holes are used for positioning, the cooling ring is sleeved on the sprue bush body, and the concentricity is ensured; the hot assembly does not need welding, the assembly speed is high, the spiral cavity is arranged on the sprue bushing, and the cooling effect is more ideal.
The embodiments of the present application are only used for illustrating the technical features disclosed in the present application, and the changes made by those skilled in the art through simple replacement still belong to the protection scope of the present application.
