Abstract
The utility model discloses an injection mold's cooling stick subassembly, its characteristics are: including barred body and connecting block, the barred body is made for highly heat -conductive material and for the cylinder size, is provided with center bore on the barred body, is provided with a plurality of axial recesses on the periphery of barred body, and the upper end of barred body is provided with corresponding center bore's butt joint, be provided with the central through hole of ability and butt joint on the connecting block, the lower terminal surface of connecting block is provided with the ring channel, and the side of connecting block is provided with the opening, central through hole and butt joint. The utility model discloses setting up center bore, recess and butt joint on the cooling stick, with the connecting block cooperation, making the cooling water get into from the central through hole of connecting block, center bore flows through to palirrhea enterings ring channel from the recess flows from the opening part, and its cooling rate is faster, and the cooling evenly is favorable to improving the productivity ratio and the qualification rate of product.
Description
Technical field
This utility model belongs to mould cooling technology field, especially relates to a kind of cooling rod assembly of injection mold.
Background technology
In prior art, injection mold is typically made up of cover half, dynamic model etc., forms die cavity, type after cover half and dynamic model matched moulds
Chamber bottom is provided with cooling well, for cooling down to product plastic.Existing injection mold is only cooled down using cooling well, its
Cooling effect is poor, low production efficiency, accordingly, it would be desirable to a kind of cooling accessory that can promote cooling well rate of cooling.
Content of the invention
The purpose of this utility model is the deficiency existing for above-mentioned prior art, provides a kind of cooling rod of injection mold
Assembly, it can accelerate to cool down the rate of cooling of well, and cooling is uniformly.
To achieve these goals, this utility model be the technical scheme is that a kind of cooling rod group of injection mold
Part, including barred body and contiguous block,
Described barred body is made for highly heat-conductive material and is cylinder type, described barred body is provided with central shaft hole, described rod
The groove of some axial directions is provided with the periphery of body, the upper end of described barred body is provided with the butt joint of corresponding central shaft hole；
The central through hole that can be docked with butt joint is provided with described contiguous block, the lower surface of described contiguous block is provided with ring
Shape groove, the side of described contiguous block is provided with opening；
Described central through hole is docked with butt joint.
Described highly heat-conductive material is beryllium copper or aluminum.
The quantity of described groove is 3～8, is evenly distributed on the periphery of barred body.
After said structure, this utility model compared to the prior art advantageously: this utility model is cold
But setting central shaft hole, groove and butt joint on rod, with contiguous block cooperation, makes cooling water enter from the central through hole of contiguous block,
Flow through central shaft hole, and reflux enters cannelure from groove, flow out at opening, faster, cooling uniformly, has its rate of cooling
Beneficial to the productivity ratio improving product and qualification rate.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of barred body.
Fig. 3 is the upward view of contiguous block.
Specific embodiment
Described below is only preferred embodiment of the present utility model, does not therefore limit protection model of the present utility model
Enclose, with reference to the accompanying drawings and examples this utility model is further illustrated.
Embodiment, as shown in Fig. 1 to Fig. 3: a kind of cooling rod assembly of injection mold, including barred body 1 and contiguous block 2, institute
State barred body 1 make for the highly heat-conductive material such as beryllium copper or aluminum and be cylinder type, described barred body 1 is provided with central shaft hole 11, institute
State the groove 12 that 6 axial directions are uniformly provided with the periphery of barred body 1, the upper end of described barred body 1 is provided with corresponding central shaft
The butt joint 13 in hole 11；The central through hole 21 that can be docked with butt joint 13 is provided with described contiguous block 2, described contiguous block 2
Lower surface is provided with cannelure 22, and the side of described contiguous block 2 is provided with opening 23；Described central through hole 21 is right with butt joint 13
Connect.
During use, barred body 1 and contiguous block 2 are installed in the cooling well of mould, central through hole 21 install water inlet pipe, opens
Outlet pipe is installed on mouth 23, cooling water enters central through hole 21 from water inlet pipe, flows through central shaft hole 11, and anti-from groove 12
Stream enters cannelure 22, exits into outlet pipe at opening 23, and therefore, faster, cooling is uniformly for its rate of cooling.
