Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor in the protection scope required by the present application.

[0026] In the prior art, the injection molding machine cannot detect and identify the size of the mold and its installation position, and only relies on the manual measurement of the size of the mold by the operator and ensures the installation position of the mold by experience. In this way, not only a lot of time is wasted, but also if the installation position of the mold is measured by manual measurement, there is a position deviation, which will also lead to poor quality of the finished product of the subsequent plastic product.

[0027] In order to solve the above technical problems, the present application provides an injection molding machine with mold detection function.

[0028] Please refer to Figures 1-2 In an embodiment of the present application, the injection molding machine with mold detection function comprises a movable mold plate 1 and a fixed mold plate 2 arranged oppositely, a mold installation area 3 for installing an injection mold is arranged between the movable mold plate 1 and the fixed mold plate 2; the injection molding machine further comprises a mold size detection mechanism 4 and a mold position detection mechanism 5, the mold size detection mechanism 4 is used for measuring the mold size of the injection mold, and the mold position detection mechanism 5 is used for detecting whether the actual installation position of the injection mold in the mold installation area 3 is consistent with the preset installation position.

[0029] The technical scheme of the present application sets the mold size detection mechanism 4 and the mold position detection mechanism 5 on the injection molding machine, measures the mold size of the injection mold by the mold size detection mechanism 4, and detects whether the actual installation position of the injection mold in the mold installation area 3 is consistent with the preset installation position by the mold position detection mechanism 5. Since the above process does not require manual intervention, the detection and identification efficiency and accuracy of the mold size and its installation position are improved, and the quality of the finished product of the subsequent plastic product is ensured.

[0030] The mold size detection mechanism 4 has many specific forms, and in the embodiment, the mold size detection mechanism 4 includes at least two groups of light emitting and receiving assemblies 401, which are respectively located at the opposite ends of the mold mounting area 3; the light emitting and receiving assemblies 401 are used to measure the mold boundary of the injection mold to determine the mold size thereof. In this way, the two groups of light emitting and receiving assemblies 401 respectively located at the opposite ends of the mold mounting area 3 are used to ensure the mold boundary of the opposite ends of the injection mold, so as to determine the mold size of the injection mold, so that the mold size of the injection mold is effectively determined under the premise of setting as few light emitting and receiving assemblies 401 as possible, thereby reducing the detection equipment investment cost of the enterprise.

[0031] Specifically, each group of light emitting and receiving assemblies 401 includes a light emitting device 402 and a light receiving device 403, which are respectively installed on the movable die plate 1 and the fixed die plate 2; for the convenience of description, the technical solution of the light emitting device 402 installed on the fixed die plate 2 and the light receiving device 403 installed on the movable die plate 1 is adopted in the present application. In this way, since the injection mold is installed between the movable die plate 1 and the fixed die plate 2, the light receiving device 403 receives the light signal from the light emitting device 402, and if the injection mold exists on the light signal propagation path, the light receiving device 403 can only receive part of the light signal; then the data information of the blocked light signal is calculated by the background computer program, so as to obtain the mold boundary signal of the injection mold, and the mold size of the injection mold can be determined according to the mold boundary signal.

[0032] It should be noted that the installation structure between the light emitting device 402 and the light receiving device 403 and the movable die plate 1 and the fixed die plate 2 adopts an embedded installation mode, so that the light emitting device 402 and the light receiving device 403 will not hinder the installation of the injection mold and the movable die plate 1 and the fixed die plate 2.

[0033] Further, the light emitting device 402 and the light receiving device 403 are inclinedly arranged in a linear structure; the inclination angle between the light emitting device 402 and / or the light receiving device 403 and the horizontal line is 30-60°. It can be understood that, as shown in the accompanying drawings, Figure 3As shown, since the injection mold is generally in a square structure, when the square structure injection mold blocks the linear structure light emitting device 402 / light receiving device 403 arranged obliquely, part of the light signal is blocked by the injection mold, and the parameter value of the boundary line distance from the mold core 1 axis position is calculated by the computer program; since the two groups of light emitting and receiving components 401 are located at the opposite ends of the mold installation area 3, the length and width dimensions of the injection mold can be calculated by combining the two. It can be understood that if the light emitting device 402 / light receiving device 403 is arranged vertically, if the boundary line of the injection mold cannot reach its position, the injection mold cannot block the light emitting device 402 / light receiving device 403, so that the technical solution of the present application cannot be effectively implemented. In this embodiment, the inclination angle between the light emitting device 402 and the light receiving device 403 and the horizontal line is 45°.

[0034] Wherein, the specific form of the above mold position detection mechanism 5 is various, in this embodiment, the mold position detection mechanism 5 includes a plurality of first distance measuring devices 501, the first distance measuring device 501 is installed on the movable mold plate 1 or the fixed mold plate 2, and the measuring end of the first distance measuring device 501 faces the end surface of the injection mold for installation with the movable mold plate 1 or the fixed mold plate 2. In order to facilitate the description, the first distance measuring device 501 is installed on the fixed mold plate 2 in the technical solution of the present application. By using the first distance measuring device 501 to detect the distance between itself and the injection mold, under normal circumstances, since the distance between the end surface of the injection mold for installation with the fixed mold plate 2 and the fixed mold plate 2 is equal everywhere, the distance data measured by the plurality of first distance measuring devices 501 should be consistent; if the injection mold is offset, so that the distance between the end surface of the injection mold for installation with the fixed mold plate 2 and the fixed mold plate 2 is inconsistent everywhere, at this time, compare the theoretical distance with the actual distance, if the error is within the specified allowable error, it is determined that the injection mold is in the standard position, if the error exceeds the allowable error, it is determined that the injection mold is in the offset state, and the installation position of the injection mold needs to be adjusted by the subsequent operator.

[0035] Specifically, the mold position detection mechanism 5 includes at least four first distance measuring devices 501, and the at least four first distance measuring devices 501 are respectively located in the upper side region, the lower side region, the left side region and the right side region within the mold installation area 3. By combining the plurality of first distance measuring devices 501 located in different regions of the mold installation area 3, the accuracy of detecting the offset of the injection mold is improved.

[0036] It should be noted that the installation mode between the first distance measuring device 501 and the movable mold plate 1 and the fixed mold plate 2 adopts an embedded installation structure, so that the first distance measuring device 501 will not hinder the installation of the injection mold and the movable mold plate 1 and the fixed mold plate 2.

[0037] Further, the mold position detection mechanism 5 comprises a plurality of second distance measuring devices 502, which are installed on the base 7 of the injection molding machine, and the measuring ends of the second distance measuring devices 502 face the lower end face of the injection mold. In this way, since the first distance measuring device 501 can only be used to measure whether the injection mold is tilted and biased, if the injection mold is rotated and biased around its axis, since the distance between the end face of the injection mold used to be installed with the fixed mold plate 2 and the fixed mold plate 2 remains consistent, the first distance measuring device 501 cannot detect it; Based on the above consideration, the second distance measuring device 502 is arranged on the base 7 of the injection molding machine, and the lower end face of the injection mold is detected by the plurality of second distance measuring devices 502 to determine whether the injection mold is rotated and biased. By combining the first distance measuring device 501 and the second distance measuring device 502, the detection and identification accuracy of the installation position of the injection mold can be more effectively improved. One side of the base 7 is fixedly connected with the fixed mold plate 2, and the other side of the base 7 is slidably connected with the movable mold plate 1, and the movable mold plate 1 moves towards or away from the fixed mold plate 2 along the base 7.

[0038] Further, the plurality of second distance measuring devices 502 are linearly distributed along a preset line, and the preset line is perpendicular to the advancing direction of the movable mold plate 1. In this way, since the advancing direction of the movable mold plate 1 is generally linearly moving along the axis direction of the injection mold, the above design ensures that the plurality of second distance measuring devices 502 can accurately measure whether the injection mold is rotated and biased around its axis.

[0039] It should be noted that the installation mode between the second distance measuring device 502 and the base 7 adopts an embedded installation structure, so that the second distance measuring device 502 will not hinder the movement of the movable mold plate 1 relative to the fixed mold plate 2.

[0040] The first distance measuring device 501 and / or the second distance measuring device 502 adopts an optical distance sensor. In this way, since the commonly used optical distance sensor on the market is used as the first distance measuring device 501 and the second distance measuring device 502, it has simple structure and strong practicability.

[0041] As a preferred scheme of the above embodiment, the injection molding machine comprises an alarm device 6, which is electrically connected with the mold size detection mechanism 4 and the mold position detection mechanism 5. In this way, when the actual mold size detected by the mold size detection mechanism 4 does not match the expected mold size, it is determined that the injection mold is incorrectly installed at this time; when the actual installation position detected by the mold position detection mechanism 5 does not match the preset installation position, it is determined that the injection mold is offset at this time. The occurrence of the above two conditions will trigger the alarm signal of the alarm device 6 to remind the operator to pay attention in time. In the embodiment, the alarm device 6 can be an alarm lamp, an alarm bell or other devices with an alarm function.

[0042] In addition, the alarm device 6 is also electrically connected with a braking device (not shown in the figure), which is used to suspend the operation of the injection molding machine, so as to ensure that the injection molding machine cannot work when the above two conditions occur, and to avoid the production of injection molded products with quality problems. Specifically, the braking device can be a brake or other devices with a braking function, which are all optional specific implementation manners, and the present application is not limited thereto.

[0043] It should be noted that other contents of the injection molding machine with mold detection function disclosed in the utility model are prior art, which will not be described here.

[0044] The above is only an optional embodiment of the utility model, and does not limit the patent range of the utility model. Any direct / indirect application of the utility model in other related technical fields is included in the patent protection range of the utility model.
