Description
Technical field
The utility model is related to a kind of cooling devices, and in particular to a kind of plastic mould sprue bush cooling device.
Background technology
Cold to detour injection mold in process of production, major ingredient handle is thick compared with expecting connection section point with branch, needs longer
Time cools down.If major ingredient not cooling down and mold completely, is expected soft, deformation, without accurate position, make injection molding machine
Tool hand can not ensure to press from both sides out major ingredient handle, so as to losing in mold, mold parting surface be made not press thoroughly, Xia Yimo major ingredient
Production can not be molded, so as to influence the full-automatic unmanned production of injection molding machine.If cooling time is long, the total of single mode is increased
Production time reduces production efficiency, increases product cost.And there is processing technology complexity, processing weeks for hot runner mold
Phase is long, and die cost is high, more demanding to injection lathe in production, at the same change the mold in manufacture process it is cumbersome, in
The mold of be pilot and it is inapplicable the characteristics of.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of plastic mould sprue bush cooling device, cooling effects
Rate is high, saves the time.

A kind of plastic mould sprue bush cooling device, including the coolant jacket being set on the periphery wall of sprue bush, coolant jacket
The upper side outer wall close to the nearly mouth end of sprue bush is equipped with water inlet, close to the opposite side at the nearly mouth end of sprue bush on coolant jacket
Outer wall is equipped with water outlet, is equipped with stepped part close to one end of the port of export of sprue bush on coolant jacket, set is fixed on coolant jacket
Housing in stepped part periphery, there are gaps between the inner wall of housing and the periphery wall of stepped part to form annular cooling chamber, described
The first passage of connection water inlet and annular cooling chamber is equipped on coolant jacket in the side wall of water inlet, close to going out on coolant jacket
The second channel of connection water outlet and annular cooling chamber is equipped in the side wall at the mouth of a river.
Preferably, the coolant jacket and housing are connected through a screw thread, wherein close to the periphery wall of stepped part on coolant jacket
External screw thread is equipped with, puts on be equipped with and the matched internal thread of external screw thread close to one end of water inlet outside.
Preferably, annular slot is offered on the coolant jacket on equipped with externally threaded periphery wall, is set in annular slot
There is the first rubber seal with housing sealing cooperation.
Preferably, the stepped part is equipped with annular notch close to the periphery wall of the port of export of sprue bush, in annular notch
Equipped with the second rubber seal with housing sealing cooperation.
Preferably, the section of the housing is U-shaped, and housing center offers the centre bore with annular notch sealing cooperation.
Preferably, the water inlet is equipped with water inlet tap, and water outlet is equipped with faucet.
The utility model has the advantage of the utility model is arranged with coolant jacket, coolant jacket on the periphery wall of sprue bush
Inlet and outlet are equipped with, cooling water enters through water inlet and first passage in annular cooling chamber, then cold by annular
But chamber enters second channel, then outside water outlet outflow mold, so as to be cooled down to sprue bush, reaches cooling major ingredient handle and divides
For branch material the purpose of junction, cooling efficiency is high, the 4-5 seconds cooling time of mold can be reduced in manufacture process, greatly
The big cost for improving production efficiency, reducing product, improves competitiveness of the enterprise in market.
