The beneficial effects of the utility model include: the mould has good drainage effect, avoids the cooling water from remaining in the mould, avoids the corrosion of the mould, avoids the residual cooling water from entering the cavity, and is beneficial to improving the product quality.
Description
Technical Field
The utility model relates to a die casting die field, concretely relates to die casting die that drainage is good.
Background
The cooling of the die-casting die can be divided into external cooling and internal cooling, wherein the external cooling is to spray a spray head on the surface of a die cavity for cooling after the casting is demoulded, and spray a demoulding agent; the inner cooling is the circulation cooling water which is introduced into the mould and is the main cooling mode of the mould. The cooling water has a great influence on the die casting mold and the product in the cooling process.
1. When the spraying robot cools the die, water in the spraying robot is remained in the die through the die core and the die frame gap, the time can corrode the die for a long time, and the service life of the die is shortened.
2. In the internal cooling process (point cooling is mainly considered), the cooling water is difficult to avoid and is not omitted, and the cooling water is remained in the clearance between the back of the mold core and the mold frame, so that the mold can be corroded for a long time. The cooling water can also enter the cavity through the ejector rod hole and the core hole of the mold core, so that the defects of product air holes, watermarks and cold shut are caused.
Disclosure of Invention
To the weak point among the above-mentioned prior art, the utility model provides a die casting die that drainage is good, its fine will remain the cooling water and discharge from the mould, the corruption of having avoided the mould and cooling water entering die cavity influence product quality.
In order to achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides a die casting die that water drainage is good which characterized in that: including vertical arrangement's framed and mold core, the mold core sets up the middle part of framed, be provided with a plurality of extensions on the framed some cold charge is put in the mold core, the mold core back has some cold holes, all is provided with water drainage tank in the below of every cold hole, framed with the lowest of mold core contact has the through-hole that bores through to ground side, water drainage tank follows the back of mold core is the crotch shape and assembles through-hole department.
Further, the water drainage tank is the circular arc recess, the circular arc diameter of circular arc recess is 10mm, the degree of depth of circular arc recess is 3mm.
Furthermore, the drainage grooves extend towards the ground side and avoid the through holes in the mold core.
Further, a wire cooling device is arranged on the mold frame and surrounds the mold core.
The beneficial effects of the utility model include: the mold has a good drainage effect, avoids the cooling water from remaining in the mold, avoids the corrosion of the mold, avoids the residual cooling water from entering the cavity, and is favorable for improving the product quality.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 isbase:Sub>A cross-sectional viewbase:Sub>A-base:Sub>A of fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the following specific embodiments and accompanying drawings.
A die-casting die with good water drainage performance as shown in figures 1-2 comprises a die frame 1 and a die core 2 which are vertically arranged, wherein the die core 2 is arranged in the middle of the die frame 1. A plurality of spot cooling devices extending into the mold core 2 are arranged on the mold frame 1, and a line cooling device 6 is arranged on the mold frame 1 around the mold core 2. Therefore, the mold has good cooling performance, the spot cooling holes of the spot cooling device need to be punched on the mold core 2 from the mold frame 1, cooling water omission is inevitably generated at the disconnection position, the omitted cooling water is left in the gap between the mold core 2 and the mold frame 1, the mold is corroded for a long time, the cooling water is more likely to enter the cavity along the ejector rod hole and the mold core hole, and the defects of product air holes, watermarks and cold insulation are caused in the die casting process.
The embodiment of the utility model provides a on the some cold hole 3 at the 2 backs of mold core and the 1 contact surface of framed, and all set up water drainage tank 4 in the below of every cold hole 3, consequently can guide the discharge with the cooling water that overflows here. And the lowest part of the die frame 1, which is in contact with the die core 2, is provided with a through hole 5 which is drilled through to the ground side, and the through hole 5 is used for discharging water out of the die. Because the mold core 2 is provided with a plurality of spot cooling holes 3, the drainage grooves 4 in the embodiment converge to the through holes 5 along the inner side end surface of the mold frame 1 in a crotch shape. Water drainage tank 4 is the circular arc recess, and the circular arc diameter of circular arc recess is 10mm, and the degree of depth of circular arc recess is 3mm, and this water drainage tank 4's structure is convenient to leak assembling of cooling water and is discharged, and water drainage tank 4 all extends to ground side for water is flowed out naturally by gravity, can not be detained, and water drainage tank still need avoid the through-hole on the mold core 2, prevents that water from following through-hole entering type intracavity.
Because water drainage tank 4 is the crotch shape network and distributes at the mold core 2 back, consequently sprays the cooling water, also can discharge along with water drainage tank 4's guide after getting into the mould from the clearance of mold core 2 and framed 1, the through-hole 5 of drainage sets up the lower extreme in addition, and the through-hole 5 diameter is 14mm, can the at utmost with the water discharge.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
