Abstract
The invention provides a mould, which is provided with a first template, a second template and a tooth mold insert arranged in the first template. The first template is provided with a first joint face and a first side face. The second template is provided with a second joint face and a second side face. The mould is further provided with a controller, a driving device, an infrared ray sensor arranged on the first side face and a locating bolt arranged on the second side face. The sensor has a transmitting point. The locating bolt is provided with a first side wall and a second side wall adjacent to the first side wall. The first side wall is separated from the second side face and the second side wall is connected with the second side face. The distance between the infrared ray transmitting point and the first joint face is the same as the distance between the end part of the second side wall, far away from the first side wall, and the second joint face. The transmitting point of the sensor emits the infrared ray which is reflected to the sensor by the first side wall. The sensor outputs control signals to the controller according to the reflected ray. The driving device drives the tooth mold insert under the control action of the controller.
Description
Technical field
The present invention relates to a kind of mould, especially a kind of mould for ejection formation.
Background technology
Ejection forming technique refers to injection material is added in the barrel of ejaculator, through being heated to molten condition, under the promotion of the screw rod of ejaculator or plunger, enters the die cavity of mould through the running gate system of nozzle and mould, injection material hardening by cooling moulding.
Present mould penetrates product, such as fruit product screw thread is arranged, and generally all enters son with tooth and comes the moulding screw thread.After the die sinking, tooth enters son under the drive of motor, is rotating and is withdrawing from product.
Yet, all is to penetrate board as the operation interface of motor generally, sometimes operating personnel's carelessness, also not die sinking with regard to starter, and not die sinking, tooth enters son can not be withdrawed from, and so, not only can damage product, also can damage tooth and enter son, cause expense to increase, production efficiency is low.
Summary of the invention
In view of this, be necessary to provide a kind of tooth that prevents to enter sub impaired mould.
A kind of mould, be used for the threaded profiled member of forming device, it has first template, second template and a tooth that is installed in described the first template enter son, described the first template has first land area and first side adjacent with described the first land area, described the second template has second land area that matches with described the first land area and second side adjacent with described the second land area, described tooth enters son and is used for the moulding screw thread, described mould further has controller, drive unit, be arranged on the infrared sensor on described the first side and be arranged on fastening screw on described the second side, described infrared sensor has an infrared emitting point, described fastening screw has the first side wall and second sidewall adjacent with the first side wall, the second side of the first side wall of described fastening screw and described the second template is separated, the second sidewall of described fastening screw links to each other with the second side of described the second template, described infrared emitting point to the distance of described the first land area equals described the second sidewall away from the end of the described the first side wall distance to described the second land area, the infrared emitting point of described infrared sensor sends infrared ray, reflexed to described infrared sensor by the first side wall, described infrared sensor outputs control signals to described controller according to reflection ray, and described drive unit drives described tooth and enters son under the control action of described controller.
Compared with prior art, the infrared sensor of mould provided by the invention outputs control signals to described controller according to reflection ray, described drive unit drives described tooth and enters son under described controller control action, thereby the situation of having avoided not die sinking just to move back tooth produces, reduced the spoilage that profiled member and tooth enter son, directly reduce cost, improved production efficiency.
Description of drawings
The mould schematic diagram that is in die opening state that Fig. 1 provides for the embodiment of the invention.
The mould schematic diagram of the matched moulds state that is in that Fig. 2 provides for the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
See also Fig. 1, it provides a kind of mould 10 that is under the die opening state for the embodiment of the invention, and it is used for the threaded profiled member (not shown) of forming device.This mould 10 comprises that the first template 12, the second template 14, installing the first template 12 interior teeth enter 16, controllers 18 of son and the drive unit 19 by controller 18 controls.This first template 12 can move relative to the second template 14.This tooth enters son 16 and is used for the moulding screw thread.Certainly, this tooth enters son and 16 also can be installed in the second template 14.
This first template 12 has the first land area 122, one first side 124 and the infrared sensor 126 that be arranged on first side 124 on adjacent with the first land area 122.This infrared sensor 126 has an infrared emitting point 128.The distance of these infrared reflection point 128 to first land areas 122 is L1.
This second template 14 has second land area 142 that matches with this first land area 122, one second side 144 and the fastening screw 146 that be arranged on second side 144 on adjacent with the second land area 142.This fastening screw 146 has a first side wall 148 and second sidewall 149 adjacent with the first side wall 148.This first side wall 148 and the second side 144 are separated, and it is used for reflecting the infrared ray perpendicular to the first side 124 of being launched by infrared emitting point 128.Described the second sidewall 149 and the second side 144 join.This first side wall 148 equals L1 away from the distance L 2 of end to the second land area 142 of this second sidewall 148, so that this infrared sensor 126 is when sensing fastening screw 146, the first template 12 and the second template 14 be matched moulds just.
Preferably, in the present embodiment, this fastening screw 146 is L-type perpendicular to the cross section of the second side 144, and the first side wall 148 of this fastening screw 144 is parallel to these the second side 144, the second sidewalls 149 perpendicular to the second side 144.
For reflected infrared ray better, the first side wall 148 of this fastening screw 146 and sensor 126 relative surfaces are provided with an infrared reflection body 15.In the present embodiment, this infrared reflection body 15 is the infrared reflection sheet.Certainly, this infrared reflection body 15 also can be infrared reflection film.
See also Fig. 2, the infrared ray of the infrared sensor 126 emission latch 146 that is positioned reflexes to namely matched moulds state of infrared sensor 126(), this infrared sensor 126 outputs control signals to controller 18 according to reflection ray, and drive unit 19 can not start under controller 18 control actions.
When the infrared ray of sensor 126 emission latch 146 reflex times (namely die opening state) that are not positioned, it can accept the reflection ray of other object, and according to reflection ray to controller 18 output another one control signals enter son 16 rotations and withdraw from profiled member to drive tooth so that this controller 18 starts drive units 19.
Because the sensor 126 of mould 10 is used for sensing fastening screw 146, to determine that mould 10 is in die opening state or matched moulds state, if die opening state, controller 18 accessory drives 19 allow its driving tooth enter son 16 rotations and withdraw from, thereby the situation of having avoided not die sinking just to move back tooth produces, reduce the spoilage that profiled member and tooth enter son 16, directly reduced cost, improved production efficiency.
In addition, those skilled in the art can also do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
