[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0019] Reference to“an embodiment” herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is explicitly contemplated that embodiments described herein can be combined with other embodiments in combinations other than the combinations explicitly set forth herein.

[0020] Based on the existing mold, after long time use, the upper die or the lower die is easy to leave the injection molding material used in the injection molding process on the forming surface, which causes the forming surface to be uneven and affects the clamping problem. Please refer to Figures 1-4 The present application provides an embodiment to solve the above problems, specifically including an upper die 1 and a lower die 2, the upper die 1 and the lower die 2 are respectively provided with a first forming surface 11 and a second forming surface 21 matched with each other. It can be understood that during the injection molding process, when the upper die 1 and the lower die 2 are clamped, the first forming surface 11 of the upper die 1 and the second forming surface 21 of the lower die 2 will abut, and a corresponding injection cavity will be formed for product forming; preferably, the second forming surface 21 is provided with a protruding portion 22, the first forming surface 11 is provided with a groove 12 for accommodating the protruding portion 22, the inner wall of the groove 12 is provided with two symmetrically arranged elastic buckles, each elastic buckle is internally provided with an electric wire, the protruding portion 22 is provided with a channel penetrating through opposite sides thereof, a conductive member 4 is installed in the channel, the two elastic buckles clamp the conductive member 4 from both sides of the conductive member 4, so that the electric wires in the two elastic buckles are mutually conductive, the side surface of the upper die 1 is provided with a signal lamp 5 and a power supply 6, the signal lamp 5 is electrically connected with the power supply 6, the electric wire of one elastic buckle is electrically connected with the signal lamp 5, and the electric wire of the other elastic buckle is electrically connected with the power supply 6;

[0021] The specific working principle of the embodiment is as follows: the existing driving mechanism is used to drive the upper die 1 and the lower die 2 to approach each other, and the groove 12 cooperates with the protruding part 22 to preliminarily guide and position the upper die 1 and the lower die 2. When the protruding part 22 enters the groove 12, the two symmetrically arranged elastic buckles are extruded by the protruding part 22 and move towards the inner wall of the groove 12. At this time, although the front ends of the two elastic buckles abut against the protruding part 22, the protruding part 22 is made of a material that is not conductive except for the conductive part 4, so the wires inside the two elastic buckles cannot be conductive. Only when the protruding part 22 is deeply inserted to the predetermined position (i.e., the accurate molding position of the upper die 1 and the lower die 2), the two elastic buckles can be in communication with the conductive part 4, the circuit of the signal lamp 5 and the power supply 6 is conductive, and the signal lamp 5 can be turned on. The operator on site can determine whether the upper die 1 and the lower die 2 are in place according to whether the signal lamp 5 is turned on.

[0022] In some embodiments, the protruding part 22 is provided with arc-shaped grooves on opposite sides, the inner wall of the groove 12 is provided with a relief groove for installing the elastic buckle, the elastic buckle includes a buckle part 31 and a spring 32, the buckle part 31 has opposite first and second end faces, the first end face is curved and used for cooperating with the arc-shaped groove, and the spring 32 is arranged between the second end face and the inner wall of the relief groove. The curved surface of the buckle part 31 cooperates with the arc-shaped groove on the protruding part 22 to achieve accurate positioning. In addition, when the protruding part 22 enters the groove 12, the protruding part 22 first contacts the curved surface of the buckle part 31. The design of the curved surface allows the protruding part 22 to push the buckle part 31. Preferably, the bottom surface of the relief groove is connected with a limiting tube 121, and the second end face is connected with a support rod 33 which is slidingly connected in the limiting tube 121. It can be understood that, in order to prevent the buckle part 31 from being dislocated during reciprocating movement, the support rod 33 arranged on the buckle part 31 cooperates with the limiting tube 121 to play a limiting and guiding role, preventing the buckle part 31 from deviating.

[0023] In some embodiments, the two arc-shaped grooves are connected by a channel, and the channel is arranged at the bottom of the bottom surface of the arc-shaped groove. The conductive part 4 includes a copper column which is a flat cuboid, and the thickness of the copper column is not more than 3 mm. Arranging the copper column in the channel not only serves as an element for conducting electricity, but also strengthens the structural strength of the protruding part 22 because the copper column itself is metal. The limitation of the thickness of the copper column is necessary. In the embodiment, if the thickness of the copper column is too thick, the two elastic buckles may be in communication with the copper column before the protruding part 22 is deeply inserted to the predetermined position. Therefore, the thickness of the copper column needs to be controlled within a certain range to prevent misjudgment.

[0024] Regarding the power supply 6, the power supply 6 can be a rechargeable battery or a removable and replaceable battery can be installed by configuring a corresponding slot on the side of the upper mold 1. The specific wiring connection method is well known to those skilled in the art.

[0025] It should be noted that the terms "first," "second," etc., used in this document are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
