Weld mark influences product strength and appearance.
Utility model content
The utility model provides a kind of plastic processing device that can eliminate weld mark, and technical solution is as follows:
A kind of plastic processing device that can eliminate weld mark, including mold, heating tube, computer heating control switch and warming line
Two sprue gates are arranged in circle, mold, and heating tube is located at position among two sprue gates of mold periphery, and warming coil includes temperature
Induction metal plate, contact I, DC power supply, iron core and the coil being wound on outside iron core, sheet metal are located at two casting of mold wall surface
Close to placement, when sheet metal expanded by heating, contacts with contact I for mouthful intermediate position, sheet metal and contact I, sheet metal, contact I, electric
Source is connected with coil, and when sheet metal cooling meat separates with contact I.
Computer heating control switch includes armature and contact II, and armature, contact II are connected with heating tube, and armature is opposite with iron core to be put
It sets, warming coil determines that computer heating control switches on-off according to temperature height.
Further, heat-conducting layer is arranged in the mold wall surface close with heating tube.
A kind of plastic processing device that can eliminate weld mark provided by the utility model, among two sprue gates of mold
Heating tube is arranged in position, so that two strands of plastic solutions is sufficiently finally combined together in intersection's dissolution, can eliminate weld mark.Due to
Using warming Coil Detector intersection temperature, when temperature rises to set temperature, sheet metal expansion increases closing coil and supplies
Circuit, iron core are sucked armature and disconnect computer heating control switch, avoid temperature excessively high, when temperature is lower than set temperature, sheet metal
It shrinks and disconnects coil power supply, iron core release armature heats computer heating control switch connection heating tube.The plastic processing apparatus structure
Simply, reliable operation can eliminate weld mark well, it is ensured that product strength and surface aesthetic.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is

Geat, 31- armature, the contact 32- II, 41- sheet metal, the contact 42- I, 43- power supply, 44- iron core, 45- coil, 5- heat-conducting layer.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
As shown in Figure 1, a kind of plastic processing device that can eliminate weld mark, including mold 1, heating tube 2, computer heating control are opened
3 and warming coil 4 are closed, two sprue gates 11 are arranged in mold 1, and heating tube 2 is located at the middle part at the 1 periphery sprue gate Liang Ge 11 of mold
Position, warming coil 4 include temperature sense sheet metal 41, contact I 42, power supply 43, iron core 44 and the coil 45 being wound on outside iron core, gold
Belong to positions among two sprue gates that 41 are located at 1 wall surface of mold, sheet metal 41 and contact I 42 close to placement, sheet metal 41 by
It is contacted when thermal expansion with contact I 42, sheet metal 41, contact I 42, power supply 43 are connected with coil 45, when 41 cooling meat of sheet metal
