Abstract
The invention relates to the technical field of injection dies, particularly to an injection die with a heat insulating runner. The injection mold sequentially comprises a fixed clamping plate, an upper runner plate, a lower runner plate, a fixed die plate, an ejection plate, a movable die plate and a mold core fixing plate from top to bottom, wherein a plurality of mold cores are arranged on the upper surface of the mold core fixing plate; a locating ring is arranged at the center of the upper surface of the fixed clamping plate; a main runner bushing is embedded in the locating ring; a plurality of sub-runners are uniformly distributed on the upper runner plate and the lower runner plate jointly; a plurality of heating probes are arranged on the upper runner plate, the heating probes can be inserted into sub-runner sprue parts respectively, and the tips of the heating probes can stretch into a sprue area, so that plastic at the sprue part is kept in the molten state. According to the injection die, the heating probes are arranged at the sub-runner sprue parts, and the tips of the heating probes stretch into a sprue area, so that plastic at the sprue part is kept in the molten state.
Description
Technical field
The present invention relates to the technical field of injection mold, especially a kind of injection mold with heat-insulating hot channel.
Background technology
Injection mold is the instrument producing plasthetics, and the material melted that is heated is injected die cavity by high pressure by it, after cooling curing, obtains formed products.The heat-insulating hot channel injection mould of cavity is the class in injection mould, the heat-insulating hot channel injection mould of cavity comprises the adiabatic runner mould of cavity and the adiabatic sprue mould of cavity, wherein the melt of the adiabatic runner mould of cavity after a shutdown in runner will all solidify, next time must be removed before start, during for spot pouring mouth, during die sinking, goods are easily from cast gate fracture, need not repair, shortcoming is the easy condensation in cast gate place, can only be used for the goods that molding cycle is short and easily shaping; The cast gate of the adiabatic sprue mould of other cavity is main flow channel type, and main flow channel type feeding with gating is made good use of, and cast gate not easily solidifies, but cast gate removing extremely bothers.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of injection mold with heat-insulating hot channel, the defect that the melt overcoming the heat-insulating hot channel injection mould cast gate place of existing cavity easily solidifies.
The technical solution adopted for the present invention to solve the technical problems is: a kind of injection mold with heat-insulating hot channel, has the top clamping plate, upper reaches guidance tape, dirty guidance tape, solid plate, push piece plate, moving platen and the core fixing plate that set gradually from top to bottom; The upper surface of described core fixing plate is provided with multiple core, the center position of described top clamping plate upper surface is provided with locating ring, described locating ring has been embedded in sprue bush, described upper reaches guidance tape and dirty guidance tape are evenly equipped with multiple runner jointly, upper reaches guidance tape is provided with multiple heated probe that can be inserted into runner cast gate position respectively, the tip of heated probe reaches gate area, makes the plastics at cast gate position remain molten condition.
Further, the solid plate described in technique scheme is provided with the die mold insert around core distribution and gate bush, so that meet the shaping demand of plastic products.
Further, the cast gate that each runner described in technique scheme is formed when pouring into a mould corresponding plastic products is positioned at the middle position of plastic products, because melt flows to cast gate from runner continuously, the melt at cast gate position continues the heating of the melt being subject to passing through, make the melt being positioned at centre remain molten condition, and then allow the melt from barrel continue through and to enter die cavity.
The invention has the beneficial effects as follows: the injection mold of band heat-insulating hot channel of the present invention, by arranging heated probe at runner cast gate position, the tip of heated probe reaches gate area, the plastics at cast gate position are made to remain molten condition, namely the plastics at cast gate position are effectively avoided to solidify, decrease the cost that manpower and materials go to dredge cast gate position, substantially increase production efficiency.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The injection mold of band heat-insulating hot channel of the present invention as shown in Figure 1, has the top clamping plate 1, upper reaches guidance tape 2, dirty guidance tape 3, solid plate 4, push piece plate 5, moving platen 6 and the core fixing plate 7 that set gradually from top to bottom; The upper surface of core fixing plate 7 is provided with multiple core 8, the center position of top clamping plate 1 upper surface is provided with locating ring 9, locating ring 9 has been embedded in sprue bush 10, upper reaches guidance tape 2 and dirty guidance tape 3 are evenly equipped with multiple runner 11 jointly, upper reaches guidance tape 2 is provided with multiple heated probe 12 that can be inserted into runner 11 cast gate position respectively, the tip of heated probe 12 reaches cast gate 15 region, makes the plastics at cast gate 15 position remain molten condition.Solid plate 4 is provided with the die mold insert 13 and gate bush 14 that distribute around core 8, so that meet the shaping demand of plastic products 16.The cast gate 15 that each runner 11 is formed when pouring into a mould corresponding plastic products is positioned at the middle position of plastic products 16, because melt flows to cast gate 15 from runner 11 continuously, the melt at cast gate 15 position continues the heating of the melt being subject to passing through, make the melt being positioned at centre remain molten condition, and then allow the melt from barrel continue through and to enter die cavity.Simultaneously, heated probe 12 can not contact with the wall of cast gate 15, lose heat effect to avoid the tip temperature of heated probe 12 to decline rapidly, and heated probe 12 is also provided with corresponding heating control system, also do not salivate to keep cast gate 15 place melt neither to solidify.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
