Abstract
The invention relates to a sliding block pin device for die-casting, which comprises an insert that is provided with a pin, and is characterized in that the insert is internally provided with a main waterway channel; the two ends of the waterway channel are respectively provided with a water outlet and a water inlet; meanwhile, the pin is internally provided with an auxiliary waterway channel communicated with the main waterway channel. Therefore, the pin has the function of water cooling. The sliding block pin device not only reduces the probability of breakage caused by thermal fatigue, but also is beneficial to attachment of release agent, thus realizing the continuity of production and being worth popularization.
Description
Technical field
The present invention relates to a kind of pin, relate in particular to a kind of die casting slide block dowel means.
Background technology
As everyone knows, in casting industry, mould is a vital ring.And an important factor that influences mould is a slide block, because slide block is a dynamic factor that influences product.And in actual production, the son of having strong market potential on the slide block is easy to break.The son of having strong market potential on the slide block is under the high temperature for a long time, and mould release is difficult to attached to above the pin, and during the demoulding, aluminium liquid produces the very big power of holding tightly to pin, thereby causes pin to break easily; Another aspect pin is under the high temperature for a long time, and heat fatigue can be aggravated, and this also can cause pin to rupture easily.
Solve this situation now and probably have two kinds: a kind of is by the control spraying, increases the quantity for spray on the pin.Another kind is to change the pin that breaks by standby pin.
But, adopt first method, be difficult to control, spray very fewly, power is held in increase tightly easily, and overspray is unfavorable for moulding again; Adopt second method, increase cost on the one hand, another aspect can not guarantee the continuity of producing.
Summary of the invention
The objective of the invention is to overcome the above problem that prior art exists, a kind of die casting slide block dowel means is provided.
For realizing a kind of die casting of purpose of the present invention slide block dowel means, include and insert, inserting is provided with pin, and wherein: be provided with main waterway channel in described the inserting, the two ends of waterway channel are respectively equipped with delivery port and water inlet; Be provided with secondary waterway channel in the described pin, be communicated with main waterway channel.
Further, above-mentioned a kind of die casting slide block dowel means wherein, is provided with the water proof sheet in the described secondary waterway channel, and on an end of water proof sheet was fixed on and inserts, the other end did not contact with secondary waterway channel inwall.
Further, above-mentioned a kind of die casting slide block dowel means, wherein, described inserting is provided with fixed screw, and the water proof sheet is connected with inserting by screw.
Further, above-mentioned a kind of die casting slide block dowel means wherein, all is equipped with connecting device on described delivery port and the water inlet.
Again further, above-mentioned a kind of die casting slide block dowel means, wherein, described connecting device is a nut.
Adopt technical solution of the present invention, make pin have the function of water-cooled.Thus, can not only reduce the probability that it occurs rupturing owing to heat fatigue, also can help adhering to of mould release, can realize being worthy to be popularized the continuity of producing.
Purpose of the present invention, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the organigram of this die casting with the slide block dowel means.
The implication of each Reference numeral is as follows among the figure:
12 pins of inserting
3 main waterway channel 4 delivery ports
5 water inlets, 6 secondary waterway channels
7 water proof sheets, 8 fixed screws
9 nuts
The specific embodiment
As shown in Figure 1 die casting includes and inserts 1 with slide block pin 2 devices, inserts 1 to be provided with pin 2, and its special feature is: described inserting is provided with main waterway channel 3 in 1, and the two ends of waterway channel are respectively equipped with delivery port 4 and water inlet 5; Be provided with secondary waterway channel 6 in the described pin 2, main waterway channel 3 is communicated with.
Further, for the better current that must control in main waterway channel 3 and the secondary waterway channel 6, promptly control into water and water-out manners well, allow current can be fully, mobile in order in main waterway channel 3 and secondary waterway channel 6 smoothly, be provided with water proof sheet 7 in the secondary waterway channel 6, one end of water proof sheet 7 is fixed on to be inserted on 1, and the other end does not contact with secondary waterway channel 6 inwalls.
Simultaneously, in conjunction with the present invention's one preferred implementation, consider water proof sheet 7 and insert that quick, easy, firm installation is connected needs between 1 that inserting 1 is provided with fixed screw 8, water proof sheet 71 is connected with inserting by screw.
Certainly, considering inserts 1 can be smoothly effectively be connected with miscellaneous part such as water supply installation, nut 9 all is installed as connecting device on delivery port 4 and the water inlet 5.
Be used for seeing in conjunction with actual the making of this die casting, be connected corresponding water supply, discharging device with water inlet 5 at delivery port 4 with slide block pin 2 devices.After opening machine, by the guiding of water proof sheet 7, main waterway channel 3 has cooling water with secondary waterway channel 6 interior flowing in order.Like this, the heat fatigue that occurs can effectively be cooled off pin 2 because be in for a long time under the high temperature can effectively to prevent pin 2 in the real-world operation process of equipment, reduces the probability that it occurs rupturing owing to heat fatigue, has guaranteed the continuity of production.Moreover, owing to control pin 2 temperature by cooling water in the course of the work, can help adhering to of mould release, further reduced the heat fatigue of pin 2.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, behind employing the present invention, make pin 2 have the function of water-cooled.Thus, can not only reduce the probability that it occurs rupturing owing to heat fatigue, also can help adhering to of mould release, can realize being worthy to be popularized the continuity of producing.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
