Abstract
The utility model relates to an injection molding termination control device. The device comprises a supporting plate, a pin and a position sensor, wherein an injection runner for connecting an injection mouth with a mold injecting hole is arranged on the supporting plate; the pin is matched with a mold overflow hole and arranged on the supporting plate in a sliding manner; the sliding direction of the pin is parallel to the mold overflow hole; the position sensor is arranged on one side of the pin and used for detecting the position of the pin. In the injection molding termination control device, the pin is inserted into the mold overflow hole, so during injection molding of an injection molding machine, molten plastic can be injected through the mold injecting hole; when an overall mold chamber is filled with the molten plastic, the plastic can flow out of the mold overflow hole and pushes the pin to move; the position of the pin is detected by the position sensor; the mold chamber is proved to be filled with the plastic when the pin reaches a set position, and then the position sensor sends a corresponding signal so that the injection molding machine can be controlled to automatically stop injection molding, so the injection molding is precise, free from influences caused by factors of operators and also free from the influences caused by temperature fluctuation.
Description
Technical field
The utility model relates to a kind of injection moulding and stops control device.
Background technology
Injection moulding machine is to become after molten condition by heating of plastic particle, and by pressurizing unit, by the plastic extrusion of molten condition, the injection nozzle of the injecting head by injecting mechanism is injected into die for molding.Injection moulding machine is when injection moulding, if the material of injection is not enough, will cause the phenomenon that injection is not in place, product has scarce material, produces waste product; If it is excessive to inject, not only can cause defect ware, also can cause the waste of material.Therefore, existing injection moulding machine is to be all provided with the device of controlling injection volume conventionally, its principle is all to control inject time by prior setting, and due to the one side good experience of definite needs of inject time, general operation personnel are difficult to determine the suitable time; On the other hand, when temperature fluctuates to some extent, the mobility of the plastics of molten condition just has subtle difference, causes the injection volume within the identical time also can be different, can not reliably accurately control.
Summary of the invention
The purpose of this utility model be for overcome the deficiencies in the prior art provide a kind of easily and the injection moulding that can reliably accurately control injection volume stop control device.
In order to achieve the above object, the utility model provides a kind of injection moulding to stop control device, it is characterized in that: described injection moulding stops control device and comprises support plate, pin and a position sensor, described support plate is provided with for connecting the injection flow passage of injection nozzle and mould inlet, described pin and mould overfall match, described pin is slidably disposed on support plate, described pin glide direction parallels with mould overfall, and described position sensor is arranged on a side of described pin for surveying pin position.
The support plate that this injection moulding stops control device is arranged on the injecting head of injection machine, injection flow passage is connected injection nozzle with mould inlet, described pin is plugged in mould overfall, when injection moulding machine injection moulding, the plastics of molten condition inject from mould inlet, after whole die cavity is filled with, plastics will flow out from mould overfall, and promote pin and move, by position sensor, survey the position of pin, when arriving the position of setting, show that die cavity fills with, position sensor sends corresponding signal, control injection moulding machine and automatically stop injection moulding, therefore both accurate, can not be subject to again operating personnel's human factor impact, also can not be subject to the impact of temperature fluctuation.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
