See Fig. 1 and Fig. 2, the utility model provides a kind of mould, this mould comprises cover half 1 and dynamic model 2, one end sunken end face of dynamic model 2 is formed with at least one dynamic model groove 3, one end sunken end face of cover half 1 is formed with at least one cover half groove 13, the two ends of dynamic model groove 3 are provided with two installing holes and are formed with gathering sill 5 in installing hole, and the length direction of gathering sill 5 is perpendicular to the axial direction of installing hole; The second slide block 72 that the both sides of dynamic model groove 3 are respectively arranged with the first oblique top 61, second oblique top 62, are sheathed on the first slide block 71 in the first oblique top 61 and are sheathed in the second oblique top 62, first slide block 71 and the second slide block 72 are separately arranged in two installing holes, the outer wall of the first slide block 71 and the second slide block 72 is all outward extended with and looses core 8, the top of the first oblique top 61 and the top of the second oblique top 62 are separately fixed on the lower surface of cover half 1, and the distance between the first oblique top 61 and the second oblique top 62 increases gradually along the direction from top to bottom; Wherein, one end end face of dynamic model 2 can make the first oblique top 61 and the second oblique top 62 move to drive the first slide block 71 and the second slide block 72 close to each other until two are loosed core and 8 to be contacted with each other by dynamic model groove 3 and dynamic model groove 3 and cover half groove 13 complement each other to form forming cavity along the length direction of gathering sill 5 towards dynamic model 2 near one end end face of cover half 1 gradually, and material can enter forming cavity from the top of cover half 1 carries out shaping; One end end face of dynamic model 2 also can make the first oblique top 61 and the second oblique top 62 move to drive the first slide block 71 and the second slide block 72 along the length direction of gathering sill 5 mutually away from until two 8 disengaging dynamic model grooves 3 of loosing core towards cover half 1 away from one end end face of cover half 1 gradually.
Pass through technique scheme, when one end end face of dynamic model 2 is gradually when one end end face of cover half 1, first oblique top 61 and the second oblique top 62 move to drive the first slide block 71 and the second slide block 72 close to each other until two are loosed core and 8 to be contacted with each other by dynamic model groove 3 and dynamic model groove 3 and cover half groove 13 complement each other to form forming cavity along the length direction of gathering sill 5 towards dynamic model 2, and such material can enter forming cavity from the top of cover half 1 and carry out shaping; When one end end face gradually away from cover half 1 of one end end face of dynamic model 2, first oblique top 61 and the second oblique top 62 move to drive the first slide block 71 and the second slide block 72 along the length direction of gathering sill 5 mutually away from until two 8 disengaging dynamic model grooves 3 of loosing core towards cover half 1, now 8 to extract out in forming cavity owing to loosing core, make forming cavity not by any resistance on mold movement direction, the moulding demoulding is more smooth and easy.
In the present embodiment, change the process of mold insert for the ease of keeping in repair the core component of this mould and the isotype of injecting products, preferably, dynamic model 2 is movably set with mavable module core 9, dynamic model groove 3 is arranged on mavable module core 9.Similarly, preferred cover half 1 is movably set with fixed mold core 10, and cover half groove 13 is arranged on fixed mold core 10.Like this, the mavable module core 9 complemented one another by replacing and fixed mold core 10 just can carry out injection moulding production to akin injecting products, avoid the another set of mould of processing because of identical product tiny change, not only time saving and energy saving, and decrease raw material and the expense of mould production, avoid waste.
In the process that loosing core on above-mentioned oblique top band movable slider moves back and forth, as shown in Figure 3, in order to make 8 operations synchronously can carrying out pull or propelling movement of loosing core on the first slide block 71 and the second slide block 72, avoid due to loose core 8 motion asynchronous cause injection cycle extend or the moulding demoulding have some setbacks, preferably, the first oblique top 61 and the second oblique top 62 are symmetricly set in the both sides of dynamic model groove 3.
Form moulding blank by being extruded by the dynamic model of mould and cover half again after being injected into metal die after injection machine machine barrel hot melting plastic raw material in injection moulding process, injection nozzle for the ease of injection machine machine barrel is injected in mould, prevent the hot melting plastic cooled and solidified of its inside thus block injection nozzle, affect moulding production efficiency, preferably, the other end of cover half 1 is provided with cover half seat 11, cover half seat 11 is provided with sprue gate 4, material can flow in forming cavity by the runner from sprue gate 4 in cover half 1.
When loosing core 8 from forming cavity after extraction, the shaping need of moulding carry out demoulding process, and taking out from mold cavity after it cools completely needs a period of time again, virtually adds the injection time of single mould, causes whole injection cycle to extend, affect production efficiency.In order to solve this technical problem, make moulding without the need to the demoulding in advance when cooling completely, shorten molding cycle, preferably, the other end of dynamic model 2 is provided with dynamic model seat 12, be provided with ejecting structure between dynamic model seat 12 and dynamic model 2, the profiled member in forming cavity can eject by ejecting structure.Further, in order to optimize ejecting structure, alleviating the raw materials for production consumption of whole mould, saving production cost, preferred ejecting structure comprises the elastic component and thimble that are from bottom to top disposed with, and the top of thimble can extend to the inside of forming cavity.
In present embodiment, remain in same plane to make dynamic model and the cover half direction of motion in relative movement, preferably, the end face of cover half 1 is provided with the one in protruding and groove, the end face of dynamic model 2 is provided with the another one in protruding and groove, and projection can extend in groove.Like this, the two can not misplace when contacting, and affects the sealing of forming cavity, causes inner molten plastic generation leakage to make product surface generation overlap or burr, reduces product qualified rate.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible combination.
In addition, also can be combined between various different embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
