Description

Technical Field

[0001] The utility model relates to an injection mold with embedded hardware, in particular to a hardware in-mold in-place detection device. Background Art

[0002] In the manufacturing process of injection molded workpieces, hardware is generally fed into the molding cavity through a slider. For the relevant structure, please refer to the Chinese patent publication number CN219311851U, entitled "A positioning mechanism and injection mold for hardware injection molding", which records:

[0003] "A positioning mechanism and injection mold for hardware injection molding, belonging to the field of injection molds, including a transmission mechanism arranged on a slider seat; the transmission mechanism includes a shifting block, a first carrier and a first insert; the first carrier is provided with a first slide groove; the guide portion on the shifting block is slidably connected to the first slide groove; the mold core of the injection mold is provided with a second slide groove; the first carrier is slidably connected in the second slide groove of the mold core; the mold core is provided with a cavity A for accommodating the first insert; the shifting block on the slider seat drives the first carrier to slide along the second slide groove, and the inclined surface D of the first carrier pushes the first insert to fit with one side of the cavity A, the first insert is used to position on the hardware, and the first insert and the second insert are provided with notches for avoiding convex bumps on the hardware";

[0004] In this type of structure, although the hardware insert can be sent into the molding cavity when the slider is slid, it cannot guarantee that the hardware is reliably positioned in the cavity. Once it collides with other sliders, the hardware is easily offset, resulting in unqualified injection molding, which not only wastes materials but also affects work efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an in-mold hardware in-place detection device which can ensure that hardware is delivered in place and improve manufacturing efficiency and yield rate in view of the deficiencies of the prior art.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions.

[0007] A device for detecting hardware in place in a mold comprises a lower mold, wherein a first slider and a second slider are provided on the lower mold, a molding cavity for molding an injection molded workpiece is formed between the first slider and the second slider, a hardware insertion hole is provided at the front end of the second slider, hardware is inserted in the hardware insertion hole, and the hardware extends into the molding cavity, a detection support is fixed to the rear end of the second slider, a first tube head is provided in the detection support, the front end of the first tube head is connected to the hardware insertion hole, and the rear end of the first tube head is connected to a vacuum generator through an air pipe.

[0008] Preferably, the lower mold is provided with two first slide blocks and one second slide block.

[0009] Preferably, the two first sliding blocks are arranged symmetrically.

[0010] Preferably, a plug-in portion is formed at the rear end of the second sliding block, a socket is formed at the front end of the detection support, and the plug-in portion is inserted into the socket.

[0011] Preferably, a fixing screw is inserted into the detection support, a front end of the fixing screw extends into the socket, and a front end of the fixing screw is screwed into the plug-in portion.

[0012] Preferably, a second tube head is provided in the second sliding block, the rear end of the second tube head is flush with the rear end of the plug-in portion, the rear end of the second tube head is butted against the front end of the first tube head and the two are sealed together.

[0013] In the in-mold hardware in-place detection device disclosed by the utility model, a first slider and a second slider are simultaneously arranged on the lower mold, and the area between the first slider and the second slider forms a molding cavity for preparing the injection molded workpiece. On this basis, the hardware is pre-inserted into the hardware insertion hole at the front end of the second slider, and the hardware is pushed into the molding cavity through the second slider. During this process, the vacuum generator continuously inhales air through the air pipe, the first pipe head and the hardware insertion hole. If the hardware is pushed into place, the negative pressure obtained by the vacuum generator feedback gradually increases. If the hardware is touched or not pushed into place for other reasons, the vacuum generator issues an alarm because the negative pressure does not meet the requirements, thereby reminding the operator to check between mold closing. Compared with the prior art, the utility model can not only ensure that the hardware is delivered in place, but also improve the manufacturing efficiency and yield rate, and better meet the application requirements.
