Abstract
The utility model discloses an injection mold component structure, especially an injection mold's thimble structure, including the thimble, be equipped with the metal framework in the below of a side end of thimble, be equipped with on the interior bottom surface of this metal framework and support the diaphragm frame, be fixed with on the interior top surface that supports the diaphragm frame and pass through the outside output voltage of signal amplification circuit, and the resistance strain gauge that changes because of its mechanical deformation of voltage signal value, a side end of above -mentioned thimble runs through and gets into to the metal frame internally, and this tip apical grafting is to support the unfamiliar outer top surface that puts up on. Its technical problem who has solved " the thimble function is diversified in realizing injection mold ", when above -mentioned thimble combines to use in whole pair of injection mold, the ejector pin of ejecting product when it not only can regard as the die sinking, simultaneously, its pressure condition that can also be used for monitoring injection mold during operation, the resin in its die cavity to ensure injection mold's the precision of moulding plastics in real time, promote the quality of moulding plastics.
Description
Technical field
The utility model relates to a kind of modular construction of injection mold, particularly a kind of thimble structure of injection mold.
Background technology
Injection mold is a kind of instrument producing plasthetics; Also be the instrument giving plasthetics complete structure and accurate dimension.
Although the structure of mould may be ever-changing because plastics variety and performance, the shape of plastic products and the type of structure and injector etc. are different, basic structure is consistent.Mould forms primarily of running gate system, thermoregulating system, forming part and constitutional detail.
Above-mentioned constitutional detail includes ejector pin mechanism, in die sinking process, for the ease of taking out plastic products, needing ejecting mechanism and plastic products and the solidifying material in runner thereof being released or pull-out.Retaining plate and push pedal are in order to clamp push rod.In push rod, be generally also fixed with release link, release link makes push pedal reset when dynamic, cover half matched moulds.
But the ejector pin mechanism in existing injection mold has just only possessed this simple function above-mentioned, and it obviously cannot meet high-precision injection moulding requirement instantly.Therefore, applicant thinks and is necessary that making further structure to the ejector pin mechanism of above-mentioned injection mold or thimble improves.
Utility model content
The purpose of this utility model is the thimble structure providing a kind of injection mold in order to solve above-mentioned the deficiencies in the prior art.When the thimble of said structure uses in a whole set of injection mold, when it can be used for monitoring injection mold work, the pressure condition of the resin in its die cavity.
To achieve these goals, the thimble structure of a kind of injection mold designed by the utility model, comprise thimble, metal frame is provided with in the below of a side end of thimble, the inner bottom surface of this metal frame is provided with support diaphragm frame, the inner top surface supporting diaphragm frame is fixed with can by the outside output voltage signal of signal amplification circuit, and the resistance strain gage that voltage signal values changes because of its mechanical deformation, one side end of above-mentioned thimble runs through and enters in metal frame, and this end apical grafting is on the outer end face supporting diaphragm frame.
The operation principle of above-mentioned middle resistance strain gage makes based on strain effect, and when namely conductor or semi-conducting material produce mechanically deform under the effect of external force, its resistance value changes accordingly, thus causes the output voltage signal at its two ends to change.
The thimble structure of above-mentioned middle provided a kind of injection mold, a side end immediate roof of thimble described in its structure is connected to and is fitted with on the support diaphragm frame of resistance strain gage.After the thimble of said structure is bonded to and uses in whole pair of injection mold, when injection mold works on injection machine, above-mentioned thimble can convert the pressure condition of resin in mould to voltage signal, then output signal to computer or other various measuring instruments in real time with the form of waveform, thus monitoring is in real time realized to the Shooting Technique of injection mold.
Preferred as a kind of technology, the side end surface of above-mentioned thimble is the conical surface, and this conical surface apical grafting is on the outer end face supporting diaphragm frame.
Described in above-mentioned technology preferred version, thimble directly contacts the support diaphragm frame being fitted with resistance strain gage by the conical surface, make the force value change sensed on thimble that resistance strain gage can be sensitiveer, promote the sensitivity that resistance strain gage detects die cavity pressure inside the resin.
The thimble structure of a kind of injection mold that the utility model obtains, when it is bonded to and uses in whole pair of injection mold, it not only can as the push rod of ejecting product during die sinking; Meanwhile, when it can also be used for monitoring injection mold work, the pressure condition of the resin in its die cavity, thus the injection moulding precision guaranteeing injection mold in real time, promote injection moulding quality.
Accompanying drawing explanation

Fig. 2 be embodiment 2 a kind of schematic diagram of thimble structure of injection mold is provided.
In figure: thimble 1, metal frame 2, inner bottom surface 3, support diaphragm frame 4, inner top surface 5, resistance strain gage 6, outer end face 7.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1:
As shown in Figure 1, thimble 1 structure of a kind of injection mold that the utility model provides, comprise thimble 1, metal frame 2 is provided with in the below of a side end of thimble 1, the inner bottom surface 3 of this metal frame 2 is provided with and supports diaphragm frame 4, the inner top surface 5 supporting diaphragm frame 4 is fixed with can by the outside output voltage signal of signal amplification circuit, and the resistance strain gage 6 that voltage signal values changes because of its mechanical deformation, one side end of above-mentioned thimble 1 runs through and enters in metal frame 2, and this end apical grafting is on the outer end face 7 supporting diaphragm frame 4.
Thimble 1 structure of above-mentioned middle provided a kind of injection mold, a side end immediate roof of thimble 1 described in its structure is connected to and is fitted with on the support diaphragm frame 4 of resistance strain gage 6.After the thimble 1 of said structure is bonded to and uses in whole pair of injection mold, when injection mold works on injection machine, above-mentioned thimble 1 can convert the pressure condition of resin in mould to voltage signal, then output signal to computer or other various measuring instruments in real time with the form of waveform, thus monitoring is in real time realized to the Shooting Technique of injection mold.
