[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Reference Figure 1-Figure 3The utility model provides an embodiment: a cooling mechanism for processing a sealing cover injection mold, comprising a lower mold 1, the inner wall of the lower mold 1 is detachably mounted with an inner mold core 3 through a positioning assembly 2, and the inner mold core 3 can be replaced by sealing covers of different models and types by disassembling and replacing the inner mold core 3, and a plurality of groups of positioning blocks 6 are fixedly connected to the bottom end of the outer wall of the inner mold core 3, and a plurality of groups of positioning grooves are provided on the inner wall of the lower mold 1, and the positioning blocks 6 are plugged into the inner walls of the positioning grooves, and the positioning plugging between the two fixes the inner mold core 3 inside the lower mold 1 to avoid shaking of the inner mold core 3 when the raw material is poured and the upper mold is matched, and the inner mold core 3 is slidably connected to the inner wall of the lower mold 1, and the positioning assembly 2 comprises two groups of fixing seats 21, and cavities are provided on both sides of the lower mold 1, and the two groups of fixing seats 21 are fixedly connected to the inner wall of the cavity of the lower mold 1.

[0037] Reference Figure 2-Figure 4 The inner side wall of the fixed seat 21 is elastically connected with a block 26 through a limit spring 25. One end of the limit spring 25 is fixedly connected to the outer wall on the right side of the fixed seat 21, and the other end of the limit spring 25 is fixedly connected to the outer wall of the block 26. The function of the limit spring 25 is to automatically reset the block 26 when the inclined surface is squeezed. The outer wall on the left side of the block 26 is fixedly connected with a connecting rod 24, which passes through and is slidably connected to the inner wall of the fixed seat 21. The block 26 is slidably connected to the inner wall of the cavity of the lower mold 1. The cavity opened by the lower mold 1 is equal to the height of the block 26, thereby preventing the block 26 from moving. The end of the connecting rod 24 away from the clamping block 26 is fixedly connected to the fixing block 23, and the bottom end of the fixing block 23 is provided with an inclined surface. The outer wall of the triangular block 22 contacts the inclined surface of the fixing block 23, and the contact between the two can push the fixing block 23 to drive the connecting rod 24 and the clamping block 26 to move outward synchronously through the movement of the triangular block 22. The outer walls on both sides of the inner mold core 3 are provided with a clamping groove, and the clamping block 26 is clamped with the inner wall of the clamping groove. The clamping connection between the two can fix the position of the inner mold core 3 inside the lower mold 1 to avoid shaking of the inner mold core 3 during use. The inner wall of the fixing seat 21 is slidably connected with the triangular block 22.

[0038] Reference Figure 5-Figure 6 A connector A4 is provided on the surface of the lower mold 1, and a plurality of ventilation holes 7 are provided on the inner side wall of the lower mold 1. A fan can be connected externally through the connector A4, so that the inner mold core 3 can be cooled from the ventilation holes 7 in the guide groove at the top of the lower mold 1. A circulation pipe 8 is fixedly connected to the bottom end of the inner wall of the lower mold 1, and both ends of the circulation pipe 8 are fixedly connected to the connector B5. Connectors B5 are provided on the outer walls on both sides of the lower mold 1. Two groups of connectors B5 can be connected to the condenser through external pipes, so that the condensed water can move inside the circulation pipe 8, thereby cooling the inner mold core 3, wherein the condenser is the prior art.

[0039] Working principle: The device is basically consistent with other mold usage methods and belongs to conventional technology within the field, so it will not be elaborated here. When injection molding is required according to the shape and size of different sealing covers, different inner mold cores 3 can be replaced, and the triangular block 22 can be pushed to move laterally on the surface of the fixed seat 21, so that the inclined surface of the bottom end of the fixed block 23 can be squeezed by the inclined surface of the triangular block 22. When the inclined surfaces of the two are in contact, the triangular block 22 will squeeze the fixed block 23 to drive the connecting rod 24 to move outward on the inner wall of the fixed seat 21, so that the block 26 at the other end of the connecting rod 24 can be disengaged from the slot of the inner mold core 3. At this time, the inner mold core 3 can be easily and quickly disassembled to replace the inner mold core 3 of the corresponding sealing cover.

[0040] During processing, the water temperature inside the condenser can be lowered by starting the condenser, and enters the circulation pipe 8 through the connector B5, and flows back into the condenser from another set of connectors B5, thereby realizing water circulation, so as to continuously control the temperature of the lower mold 1, and at the same time, the inner mold core 3 is also cooled to prevent the temperature from being too high, resulting in poor molding of the sealing cover. At the same time, an external blowing device is connected to the connector A4, so that the two sides of the inner mold core 3 are ventilated through the ventilation holes 7, so that the internal sealing cover can be quickly molded.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
