The injection mold that has mold insert
Technical field:
The utility model relates to technical field of mold, relates in particular to a kind of injection mold that has mold insert.
Background technology:
Injection mold is to be used for the material that melts that is heated is injected die cavity by high pressure, behind cooling curing, obtains the device of formed products, and injection mold is applicable to the batch process of complex-shaped parts.The injecting products molding cycle is long, and manufacturing cost is high, is to belong to more difficult workpiece.The cooling fortune water design of existing injection mold can't be cooled off mold insert during injection moulding on fixed block, and mold insert can't directly import fortune water, during moulding, leans on the fixed block cooling water channel to lower the temperature, and cool time is slow, causes the production cycle longer.
The utility model content:
The purpose of the utility model is exactly the deficiency that exists to prior art and a kind of cool time and injection mold that has mold insert of molding cycle when shortening formed product is provided.
To achieve these goals; The technical scheme that the utility model adopts is: have the injection mold of mold insert, it comprise dynamic model with the cover half of the corresponding setting of dynamic model, cover half is provided with fixed block and mold insert; The top of mold insert is fixed on the fixed block; Mold insert inside offers at least one cooling water channel, and cooling water channel is provided with water inlet in the mold insert side, and cooling water channel is provided with delivery port in the mold insert top.
The material of said mold insert is a beryllium copper.
Said cooling water channel is two.
Article two, the shared water inlet of cooling water channel.
Offer the mounting groove that runs through top and bottom on the said fixed block, the top of mold insert is fixed in the mounting groove.
The side of said mold insert convexes with cooling end, and cooling water channel is located in the cooling end.
The utility model beneficial effect is: the injection mold that has mold insert that the utility model provides, and it includes fixed block, mold insert, and the top of mold insert is fixed on the fixed block, and mold insert inside offers at least one cooling water channel; Cooling water channel is provided with water inlet in the mold insert side, and cooling water channel is provided with delivery port in the mold insert top, and the utility model is through improving mould structure, and the runner of mould is shortened; And in the cooling water channel of mold insert, import fortune water, during moulding, accelerate the cooling velocity of product; Good cooling results shortens the cool time of product, and has reduced the waste material generation of mouth of a river material; Thereby shorten the formed product cycle, enhance productivity, reduce cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cutaway view of the utility model;
Fig. 3 is the decomposing schematic representation of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described; See shown in Fig. 1~3, the utility model comprise dynamic model (figure do not show) with the cover half (figure does not show) of the corresponding setting of dynamic model, cover half is provided with fixed block 1 and mold insert 2; The top of mold insert 2 is fixed on the fixed block 1; Mold insert 2 inside offer at least one cooling water channel 3, and cooling water channel 3 is provided with water inlet 31 in mold insert 2 sides, and cooling water channel 3 is provided with delivery port 32 in mold insert 2 tops.The material of mold insert 2 is a beryllium copper, can accelerate cooling velocity.
Cooling water channel 3 is two, and two cooling water channel 3 shared water inlets 31 can improve cooling effect.The side of mold insert 2 convexes with cooling end 21, and cooling water channel 3 is located in the cooling end 21.
Offer the mounting groove 11 that runs through top and bottom on the fixed block 1, the top of mold insert 2 is fixed in the mounting groove 11, and mounting or dismounting are convenient.
The utility model is through improving mould structure, the runner of mould shortened, and in the cooling water channel 3 of mold insert 2, import fortune water, and mold insert 2 materials are changed to the beryllium copper material; During moulding, accelerate the cooling velocity of product, good cooling results, the cool time of shortening product; And the waste material that has reduced mouth of a river material produces, thereby shortens the formed product cycle, drops to 15.8S by original 42S; Enhance productivity, reduce cost, the unit's of making mould material cost and the corresponding reduction of unit plastic material cost.
Certainly, the above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
