Abstract
The utility model discloses an improved hot runner mold. The improved hot runner mold comprises a fixed mold plate and a fixed mold fixing plate, wherein a spacing plate, a splitter plate and a bearing plate are sequentially arranged between the fixed mold fixing plate and the fixed mold plate; the fixed mold fixing plate is provided with a positioning ring; the center of the spacing plate is provided with a space for accommodating the splitter plate; a junction box is installed at one side of the spacing plate; the splitter plate is provided with a heating pipe; a main injection nozzle is poisoned on the middle part of the splitter plate; the bearing plate is provided with positioning holes corresponding to two hot nozzles; the splitter plate is provided with a temperature sensing wire; the temperature sensing wire passes through a wire exiting groove in the spacing plate, and is connected with a temperature control cabinet. According to the utility model, the temperature is controlled uniformly, so that the pressure loss in a runner is less; plastic in the runner is at the fused state, and has good fluidity; the surface quality and the mechanical property of the product are improved; all or most of runner waste materials can be removed; the material utilization ratio is improved; the production cost is saved.
Description
Technical field
The utility model relates to injection mold field, is specifically related to a kind of improved hot runner mould.
Background technology
According to the difference of mold runner type, injection mold is generally divided into hot runner mould and cold runner die.Stream hot flow path is by the way of heating, to guarantee the plastics maintenance molten condition of runner and cast gate, and TOP-TIP is generally comprised of several parts such as hot nozzle, flow distribution plate, temperature control box and annexes.
Hot runner mould is to utilize heater to make the interior melt of runner noncondensing mould all the time, because it is shorter than traditional moulds forming period, and more economize in raw materials, so hot runner mould is in the world today, each industrially developed country and area all obtain applying very widely.The advantage of hot runner mould has: shorten product molding cycle, production waste, does not save plastic raw materials, improves the quality of products etc.
Existing hot runner mould in use, because temperature control is not good, or because temperature control system cost is compared with high and less use, causes the poor fluidity of plastics in runner, has affected the surface quality of product.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of improved hot runner mould simple in structure, with low cost.
For solving the problems of the technologies described above, improved hot runner mould of the present utility model, comprise solid plate and cover half fixed head, between described cover half fixed head and solid plate, be provided with successively space bar, flow distribution plate and board, described cover half fixed head is provided with locating ring, space bar central authorities are provided with the space that holds described flow distribution plate, terminal box is arranged on a side of described space bar, described flow distribution plate is provided with heat-generating pipe, main nozzle is positioned at the centre position of described flow distribution plate, described board is provided with and two locating holes that hot mouth is corresponding, described flow distribution plate is provided with temp.-sensing wire, described temp.-sensing wire is connected with temperature control box through the line outlet groove on space bar.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model overall structure advantages of simple, on flow distribution plate, be provided with heat-generating pipe and temp.-sensing wire, temperature is controlled evenly, the loss of runner internal pressure is reduced, in runner, plastics have good mobility in molten condition, the surface quality and the mechanical property that have improved product, the phenomenons such as common shrink, lack of fill, weld mark, irregular colour, overlap, warpage also greatly reduce.
2, the utility model can be eliminated whole or most of runner waste material, has improved the utilization rate of material, has reduced production cost.
3, due to needn't the old material of reuse, thereby shorten molding cycle and opening stroke, further improved production efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, improved hot runner mould, comprise solid plate 5 and cover half fixed head 1, between described cover half fixed head 1 and solid plate 5, be provided with successively space bar 2, flow distribution plate 3 and board 4, described cover half fixed head 1 is provided with locating ring 11, space bar 2 central authorities are provided with the space 21 that holds described flow distribution plate 3, terminal box 23 is arranged on a side of described space bar 2, described flow distribution plate 3 is provided with heat-generating pipe 32, main nozzle 31 is positioned at the centre position of described flow distribution plate 3, described board 4 is provided with and two locating holes 41 that hot mouth 33 is corresponding, described flow distribution plate 3 is provided with temp.-sensing wire, described temp.-sensing wire is connected with temperature control box through the line outlet groove 22 on space bar 2.
Critical piece assembling of the present utility model is as follows: on solid plate 5, establish a plurality of alignment pins, by alignment pin and board 4, position fixing, locating hole 41 on board 4 aligns fixing with two hot mouths 33, flow distribution plate 3 is fixed on space bar 2 by four fixed screws, temp.-sensing wire on flow distribution plate 3 is connected with temperature control box through the line outlet groove 22 on space bar 2, terminal box 23 is arranged on to a side of space bar 2, finally loads onto cover half fixed head 1.
Operation principle of the present utility model is: power-on, heat-generating pipe 32 heating, thermal energy transfer is to flow distribution plate 3, the all sites of flow distribution plate 3 all obtains heat, by temp.-sensing wire and temperature control box, carry out temperature control, in running channel, plastics keep good molten condition, and the plastics in molten condition are from main nozzle 31 ejections.Because plastics in runner have good mobility in molten condition, thereby improved surface quality and the mechanical property of product, the phenomenons such as common shrink, lack of fill, weld mark, irregular colour, overlap, warpage also greatly reduce.
