Description

Technical Field

[0001] The present invention relates to the technical field of injection molds, and particularly relates to an injection mold capable of intelligently monitoring whether the cooling water circulation ports are closed. Background Art

[0002] An injection mold refers to the supporting mold used for injection molding. Injection molding means a method in which, at a certain temperature, a completely molten plastic material is stirred by a screw and injected into the cavity of the injection mold under high pressure, and after cooling and solidification, a molded product is obtained.

[0003] When the existing injection mold is not in use, in order to prevent external insects, dust, impurities, etc. from entering the cooling water path and causing blockage, which affects subsequent cooling applications, the input and output ports of the cooling water path of the injection mold should be sealed. However, there is no corresponding mandatory structure currently. Once the staff forgets, it is very likely that external insects, dust, impurities, etc. will enter the cooling water path and cause blockage. Summary of the Invention

When the socket joint of the present invention is connected to the cooling water input pipe or the cooling water output pipe, under the socket pressing of the cooling water input pipe or the cooling water output pipe, the inside of the cooling cooperation housing is in a power-off state at this time. And through this setting, during the injection molding operation process, when the cooling water input pipe or the cooling water output pipe has a small distance detachment from the socket joint, at this time, due to the change in the pressing position of the cooling water input pipe or the cooling water output pipe on the pressing plate, the return spring returns and rebounds to push the pressing plate forward. At the same time, the insulating spacer and the conductive sheet slide forward along the through socket. At this time, the inside of the cooling cooperation housing will be in a power-on state, and the buzzer will emit a high-decibel sound to remind the staff that the current cooling water input pipe or the cooling water output pipe has a small distance detachment from the socket joint and needs to be re-socketed and installed in time. Through this setting, it is possible to avoid the detachment of the cooling water input pipe or the cooling water output pipe during the injection molding operation process, so as to avoid the leakage and loss of cooling water.

[0013] Beneficial effects

[0014] 1. When the socket joint of the present invention is connected to the cooling water input pipe or the cooling water output pipe, under the socket pressing of the cooling water input pipe or the cooling water output pipe, the inside of the cooling cooperation housing is in a power-off state at this time. And through this setting, during the injection molding operation process, when the cooling water input pipe or the cooling water output pipe is slightly detached from the socket joint, at this time, due to the change of the pressing position of the cooling water input pipe or the cooling water output pipe on the pressing plate, the return spring returns and rebounds to push the pressing plate forward. At the same time, the insulating spacer and the conductive sheet slide forward along the through socket. At this time, the inside of the cooling cooperation housing will be in a power-on state, and the buzzer will emit a high-decibel sound, reminding the staff that the cooling water input pipe or the cooling water output pipe is slightly detached from the socket joint at present and needs to be re-socketed and installed in time. Through this setting, it is possible to avoid the detachment of the cooling water input pipe or the cooling water output pipe during the injection molding operation process, so as to avoid the leakage and loss of cooling water.

[0015] 2. When the return spring is in the extended state, the conductive sheet is in contact with the conductive component a and the power supply component. Therefore, when the socket joint of the present invention is not socketed and installed with the cooling water input pipe or the cooling water output pipe, the inside of the cooling cooperation housing will be in a power-on state. Through this setting, when the injection mold of the present invention is not in use, in order to avoid the buzzer from sounding, the rubber sleeve can be inserted and installed with the socket joint. And through the pressing of the socket joint on the pressing plate, the power inside the cooling cooperation housing is cut off, ensuring that the buzzer will not sound when the injection mold of the present invention is not in use. And through this mandatory operation of the present invention, it can effectively avoid the situation that due to reasons such as forgetting by the staff, the socket joint part is not sealed when the injection mold of the present invention is not in use, resulting in foreign insects, dust impurities, etc. entering the cooling chamber a and the cooling chamber b, causing blockage and affecting subsequent cooling applications.

Four rectangularly distributed threaded limit blind holes a105 are provided at each of the two cooling connection hole positions a104 on the front end surface of the lower mold 1. A set of cooling fitting shells 3 is provided at each of the two cooling connection hole positions a104 on the front end surface of the lower mold 1. The cooling fitting shell 3 has a square shell structure. Installation plates 301 are provided on the left and right end surfaces of the cooling fitting shell 3. Two locking bolts 302 are slidably inserted into the two installation plates 301. The locking bolts 302 are threadedly fixed to the threaded limit blind holes a105. A socket joint 3010 is provided at the center of the front end surface of the cooling fitting shell 3. A communication hole position 3011 that penetrates the rear end surface of the cooling fitting shell 3 is opened at the center of the axis of the socket joint 3010. When the cooling fitting shell 3 is installed with the lower mold 1, the communication hole position 3011 corresponds to the cooling connection hole position a104 in position. Two cooling connection hole positions b203 that are connected to the cooling cavity b206 are opened on the front end surface of the upper mold 2.

A set of cooling fitting shells 3 is provided at each of the two cooling connection hole positions b203 on the front end surface of the upper mold 2.

[0032] Among them, at the positions adjacent to the upper left corner and the lower right corner of the socket joint 3010 on the front end face of the cooling mating housing 3, a limiting storage groove 3012 is provided at each position. The limiting storage groove 3012 is in a circular groove structure, and a limiting through hole 3014 penetrating the rear end face of the cooling mating housing 3 is provided at the axial center of the two limiting storage grooves 3012; a pressing plate 304 is provided directly in front of the cooling mating housing 3. The pressing plate 304 is in a square plate structure. At the upper left corner and the lower right corner of the rear end face of the pressing plate 304, a limiting post 306 is provided. The limiting post 306 is slidably inserted into the limiting through hole 3014. A mating opening 305 is provided at the center of the front and rear end faces of the pressing plate 304. The mating opening 305 is a circular hole, and the diameter of the mating opening 305 is larger than the diameter of the socket joint 3010; a return spring 307 is sleeved around each of the two limiting posts 306. The front end of the return spring 307 is fixedly connected to the rear end face of the pressing plate 304, and the rear end of the return spring 307 is fixedly connected to the inner rear side face of the limiting storage groove 3012; when the return spring 307 is in the extended state, the rear end face of the pressing plate 304 does not contact the front end face of the cooling mating housing 3. At the position adjacent to the upper right corner of the socket joint 3010 on the front end face of the cooling mating housing 3, a through socket 3013 penetrating the rear end face of the cooling mating housing 3 is provided. The through socket 3013 is in a rectangular opening structure; a conductive component a3016 is embedded and installed on the left side face of the inner end of the through socket 3013. The conductive component a3016 is a copper conductive block. On the right side face of the inner end of the through socket 3013, a power supply component 3017 and a conductive component b3018 are sequentially embedded and installed. The power supply component 3017 is a button battery. The negative end of the power supply component 3017 faces the through socket 3013, and the positive end of the power supply component 3017 is in contact with the conductive component b3018. The conductive component b3018 is a copper conductive block; a buzzer 3015 is provided inside the cooling mating housing 3. The conductive component a3016 and the conductive component b3018 are connected to the pins of the buzzer 3015 through wires. An insulating spacer 308 is fixedly installed at the upper right corner of the rear end face of the pressing plate 304. A conductive sheet 309 is fixedly installed on the rear end face of the insulating spacer 308. Both the insulating spacer 308 and the conductive sheet 309 are slidably inserted into the through socket 3013; when the return spring 307 is in the extended state, the conductive sheet 309 is in contact with the conductive component a3016 and the power supply component 3017.

[0033] Among them, it further includes a rubber sleeve 303. The rubber sleeve 303 is inserted and matched with the socket joint 3010. When the rubber sleeve 303 is inserted and installed with the socket joint 3010, the return spring 307 is in a compressed state at this time, and the conductive sheet 309 is not in contact with the conductive component a3016 and the power supply component 3017, while the insulating spacer 308 is in contact with the conductive component a3016 and the power supply component 3017. Therefore, when the injection mold of the present invention is not in use, in order to prevent the buzzer 3015 from sounding, the rubber sleeve 303 can be inserted and installed with the socket joint 3010. By the socket joint 3010 pressing against the pressure plate 304, the conductive sheet 309 is not in contact with the conductive component a3016 and the power supply component 3017, cutting off the power supply inside the cooling cooperation housing 3, ensuring that the buzzer 3015 will not sound when the injection mold of the present invention is not in use.

[0034] Specific usage method and function of this embodiment:

[0035] When the socket joint 3010 of the present invention is connected to the cooling water input pipe or the cooling water output pipe, under the socket pressing of the cooling water input pipe or the cooling water output pipe, the return spring 307 is in a compressed state at this time, and the conductive sheet 309 is not in contact with the conductive component a3016 and the power supply component 3017, while the insulating spacer 308 is in contact with the conductive component a3016 and the power supply component 3017. Therefore, the power supply inside the cooling cooperation housing 3 is in a cut-off state at this time. Through this setting, during the injection molding operation process, when the cooling water input pipe or the cooling water output pipe is slightly detached from the socket joint 3010, at this time, due to the change in the pressing position of the cooling water input pipe or the cooling water output pipe on the pressure plate 304, the return spring 307 rebounds and pushes the pressure plate 304 forward. At the same time, the insulating spacer 308 and the conductive sheet 309 slide forward along the through socket 3013. At this time, the conductive sheet 309 will be in contact with the conductive component a3016 and the power supply component 3017, and the power supply inside the cooling cooperation housing 3 will be in a connected state. Since the conductive component a3016 and the conductive component b3018 are connected to the pins of the buzzer 3015 through wires, the buzzer 3015 will emit a high-decibel sound, reminding the staff that the current cooling water input pipe or the cooling water output pipe is slightly detached from the socket joint 3010 and needs to be re-socketed and installed in time. Through this setting, it is possible to prevent the cooling water input pipe or the cooling water output pipe from falling off during the injection molding operation process, so as to avoid the leakage and loss of cooling water;

[0036] When the reset spring 307 of the present invention is in the extended state, the conductive sheet 309 is in contact with the conductive component a3016 and the power supply component 3017. Therefore, when the socket joint 3010 of the present invention is not socketed and installed with the cooling water input pipe or the cooling water output pipe, the inside of the cooling cooperation housing 3 will be in a power-on state. Through this setting, when the injection mold of the present invention is not in use, in order to avoid the buzzer 3015 from sounding, the rubber sleeve 303 can be inserted and installed with the socket joint 3010. And through the pressing of the pressing plate 304 by the socket joint 3010, the conductive sheet 309 is not in contact with the conductive component a3016 and the power supply component 3017, cutting off the power inside the cooling cooperation housing 3, ensuring that the buzzer 3015 will not sound when the injection mold of the present invention is not in use. And through this mandatory operation of the present invention, it can effectively prevent the staff from forgetting and other reasons from failing to seal the socket joint 3010 when the injection mold of the present invention is not in use, resulting in foreign insects, dust and impurities entering the cooling chamber a106 and the cooling chamber b206, causing blockage and affecting the subsequent cooling application phenomenon;

[0037] When the present invention is injection molded, the lower mold 1 and the upper mold 2 are cooperatively installed. At this time, an injection molding cavity structure is formed between the female mold 102 and the male mold 205. The molten raw material is input into the injection molding cavity formed between the female mold 102 and the male mold 205 through pressurization from the injection hole position 201. The lower mold 1 and the upper mold 2 are respectively connected to the cooling water input pipe and the cooling water output pipe of the socket joint 3010 in each of the two groups of cooling cooperation housings 3 installed in cooperation, so that the cooling water circulates along the cooling chamber a106 and the cooling chamber b206. And because a cooling chamber a106 is provided in the lower mold 1 adjacent to the lower part of the female mold 102, the structure of the cooling chamber a106 is similar to the structure of the female mold 102, and a cooling chamber b206 is provided inside the male mold 205, and the cooling chamber b206 is similar to the structure of the male mold 205. Therefore, through the settings of the cooling chamber a106 and the cooling chamber b206 that are respectively similar to the structure of the female mold 102 and the structure of the male mold 205, it can be ensured that the injection molded part in the injection molding cavity formed between the female mold 102 and the male mold 205 is cooled evenly, ensuring the cooling effect and ensuring that there will be no adhesion phenomenon between the injection molded part and the injection molding cavity during the subsequent mold opening and demolding processes.

[0038] The above is only an exemplary embodiment of the present invention, rather than being used to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
