Abstract
The utility model relates to a split oil passage cast pin. The lower side of the upper part of the oil passage cast pin is matched with the upper side of the lower part of the oil passage cast pin; the upper part of the oil passage cast pin is arranged in one segment of a die and the lower part of the oil passage cast pin is correspondingly arranged in the other segment of the die. The utility model has compact structure and reasonable design which reduce the production cost, prevent the stress from concentrating at the right-angle part, reduce the fault rate of the oil passage and improve the production efficiency.
Description
Technical field
The utility model relates to a kind of oil circuit casting pin, especially a kind of special casting pin that prevents the fracture of oil circuit casting pin that is used on the die casting.
Background technology
At present, existing oil circuit casting pin is all-in-one-piece, generally is made up of mould mounting portion, die cavity counterpart and right-angle structure.Right-angle structure between mould mounting portion and the die cavity counterpart when aluminium liquid fills type at a high speed this position the time stress concentrate, oil circuit casting pin easily ruptures from mould right angle part.The casting pin is installed in the mould lobe, and the die casting volume is bigger, because the casting pin is prone to fault, and changes inconvenience, and this has influenced production efficiency, has also increased manpower, has increased cost.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, a kind of compact conformation, reasonable in design is provided, reduced production cost, this oil circuit casting pin has not only reduced the fracture that causes that stress is concentrated, and has correspondingly also reduced the split type oil circuit casting pin that manpower expends.
In order to achieve the above object, the technical solution adopted in the utility model is: cooperatively interact above the following and oil circuit casting pin bottom on oil circuit casting pin top, oil circuit casting pin top is loaded in the mould lobe, and the oil circuit casting sells that the bottom is corresponding to be loaded in the mould lobe.
The utility model has the advantages that:
Compact conformation, reasonable in design has reduced production cost, has avoided the stress of right angle part to concentrate, and has reduced the fault rate of oil circuit casting pin, has improved production efficiency, has reduced cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model mould valve structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, cooperatively interact above the following and oil circuit casting pin bottom 2 on the utility model oil circuit casting pin top 1, oil circuit casting pin top 1 is loaded in the mould lobe 3, oil circuit casting pin bottom 2 corresponding being loaded in the mould lobe 3.
Eliminate the right angle part between oil circuit casting pin top 1 and the oil circuit casting pin bottom 2.
Split type oil circuit casting pin is made up of oil circuit casting pin top 1 and oil circuit casting pin bottom 2.
Top 1 is sold in the oil circuit casting to the utility model and oil circuit casting pin bottom 2 is formed by being decomposed into along the right angle part at split type oil circuit casting pin.Among Fig. 1, match above the following and oil circuit casting pin bottom 2 on oil circuit casting pin top 1, mutual group becomes split type oil circuit casting pin.It is fastening in the mould lobe 3 now to be packed in oil circuit casting pin top 1, fastening in the mould lobe 3 of being packed in oil circuit casting pin bottom 2 then, eliminates the right angle part.
Claims (2)
1. a split type oil circuit casting is sold, form by oil circuit casting pin top (1) and oil circuit casting pin bottom (2), it is characterized in that: cooperatively interact above the following and oil circuit casting pin bottom (2) on oil circuit casting pin top (1), oil circuit casting pin top (1) is loaded in the mould lobe (3), corresponding being loaded in the mould lobe (3) in oil circuit casting pin bottom (2).
2. split type oil circuit casting pin according to claim 1 is characterized in that: eliminate the right angle part between oil circuit casting pin top (1) and the oil circuit casting pin bottom (2).
