Abstract
The utility model discloses a hot runner system which comprises a splitter plate, an injection nozzle and a hot nozzle, wherein the hot runner used for communicating the output end of the injection nozzle and the input end of the hot nozzle is arranged in the splitter plate; a support block is fixed on the splitter plate at the position opposite to the mounting position of the hot nozzle; and a heat insulation block is fixedly connected on the outer side of the support block. Compared with the conventional hot runner system, the hot runner system provided by the utility model has the advantages that the support block and the heat insulation block are additionally arranged onto the splitter plate, the pressure generated in the injection molding process can be balanced by the support block so as to improve the strength of the splitter plate and effectively prevent the splitter plate from being deformed, and the heat insulation block can reduce the heat transfer between the splitter plate and a mould so as to reduce the influence of overhigh temperature of the splitter plate on the mould. The hot runner system is simple in structure, and the material of the splitter plate does not need to be changed, thus being convenient for reducing the cost of the hot runner system.
Description
Technical field
The utility model relates to the injection molding technology field, is specifically related to a kind of TOP-TIP.
Background technology
Along with the continuous expansion in plastic cement products market, the demand of injection mold also constantly increases.The hot flow path technology is as key technology in the injection mold, also more and more is widely used and payes attention to.
In the hot runner mould injection process, the plastics melten gel gets in the hot flow path through the injection machine injection nozzle, is injected in the product die cavity by hot mouth or through cold runner again; In above-mentioned injection process; Flow distribution plate will bear the impact that comes from the big pressure of injector; The flow distribution plate easy deformation causes flow distribution plate and Re Zui junction to leak glue, makes that TOP-TIP can't operate as normal; If strengthen flow distribution plate rigidity, be on material cost or processing cost, all can improve from the material aspect that changes flow distribution plate.In flow distribution plate when work,, its temperature is generally higher, but mould needs relatively low operating temperature, for not influencing the operate as normal of mould, i.e. and heat insulation also quite important between flow distribution plate and the mould.
The utility model content
Deficiency to prior art; The purpose of the utility model is intended to provide a kind of TOP-TIP, can under the prerequisite that does not change the flow distribution plate material, strengthen the impact strength of flow distribution plate; Simultaneously, can effectively reduce heat transmission between flow distribution plate and the mould again.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of TOP-TIP; Comprise flow distribution plate, injection nozzle and hot mouth; Has hot flow path in the flow distribution plate with the input conducting of the output of injection nozzle and hot mouth; Be installed with the higher back-up block of a hardness on the position relative with the Re Zui installation site on the flow distribution plate, the outside of this back-up block is fixedly connected with the relatively poor heat insulation of a heat transfer property.
Back-up block and heat insulation are connected on the flow distribution plate through a bolt.
The one side that heat insulation and back-up block are fitted is provided with avoiding hollow groove.
Avoiding hollow groove extends along circular trace at the medial surface of heat insulation.
The beneficial effect of the utility model is:
Than existing TOP-TIP; The utility model is set up back-up block and heat insulation on flow distribution plate; Back-up block can the balance injection machine pressure big, increase the intensity of flow distribution plate, effectively prevent the flow distribution plate distortion; Heat insulation can reduce the heat transmission between flow distribution plate and the mould simultaneously, reduces the influence of the too high temperature of flow distribution plate to mould.The utility model is installed simple, need not to change the material of flow distribution plate, is convenient to control the cost of TOP-TIP.
Description of drawings
Fig. 1 is the structural representation of a kind of TOP-TIP of the utility model;
Fig. 2 is the zoomed-in view at A place among Fig. 1;
Fig. 3 is the structural representation of heat insulation among Fig. 1;
Fig. 4 is the B-B cutaway view of Fig. 3.
The specific embodiment
Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing:
Like Fig. 1,2,3, shown in 4; The TOP-TIP of the utility model comprises flow distribution plate 1, injection nozzle 3 and hot mouth 4; Hot flow path 2 is set in the flow distribution plate 1, and this hot flow path 2 is with the input conducting of the output and the hot mouth 4 of injection nozzle 3, and injection nozzle 3 and hot mouth 4 are installed in the both sides of flow distribution plate 1 respectively; The position relative on flow distribution plate 1 with hot mouth 4; Through bolt 8 lockings back-up block 5 and heat insulation 6 are installed, back-up block 5 is close to the surface of flow distribution plate 1,6 lateral surfaces of being close to back-up block 5 of heat insulation.
In the shunting process, the one side that flow distribution plate 1 is equipped with back-up block 5 has higher intensity, and the compression shock in the time of can bearing injection can effectively be avoided the distortion of flow distribution plate 1.In addition, flow distribution plate 1 has higher temperature when work, and this temperature is passed to after the back-up block 5, can have been avoided the too high influence to mould of flow distribution plate 1 temperature by heat insulation 6 effective isolation.In order to obtain more significant effect of heat insulation, the one side (being the medial surface of heat insulation 6) of fitting at heat insulation 6 and back-up block 5 offers avoiding hollow groove 61, can reduce the contact area with back-up block 5; Avoiding hollow groove 61 extends along circular trace at the medial surface of heat insulation 6; Increase heat insulation 6 and not only can avoid of the influence of the too high temperature of flow distribution plate 1, simultaneously, can also reduce the loss of heat in the flow distribution plate 1 mould; Reduce the heating power of flow distribution plate 1, reduced energy loss.
