Description

Technical Field

[0001] This utility model relates to the field of instrument bottom cover mold technology, and in particular to an instrument bottom cover mold that is easy to replace. Background Technology

[0002] The instrument base cover is an important component of the instrument. It is usually located at the bottom or rear of the instrument body. As part of the instrument housing, it isolates external dust, moisture, minor impacts or foreign objects, and protects internal precision circuits, sensors, pointers or displays and other core components from damage.

[0003] In the existing technology, the process of manufacturing the instrument bottom cover first requires the use of a mold. With the precise mold-closing of the upper and lower mold cavities, the molten raw materials can be quickly molded into the shape of the bottom cover that perfectly matches the design drawings, thus achieving high-precision control of product dimensions.

[0004] However, due to the large number of bolts on the mold itself, the replacement of the mold cavity directly prolongs the disassembly and installation time. It is necessary to loosen the fixing bolts of the old mold cavity one by one with tools, and then tighten them one by one after replacing the new mold cavity. Frequent bolt disassembly and assembly can easily cause component wear, reduce the tightness of the connection, and thus affect the mold closing accuracy. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figures 1-6As shown, this utility model provides a technical solution: a replaceable instrument bottom cover mold, including a replacement mechanism 1. The inner wall of the replacement mechanism 1 is provided with a limiting mechanism 2. The replacement mechanism 1 includes a lower mold base 11, and an upper mold base 15 is provided above the lower mold base 11. The upper part of the lower mold base 11 is radially corresponding to the upper mold base 15. An upper mold cavity 14 is provided on the bottom side of the upper mold base 15. The bottom side of the upper mold base 15 contacts the top side of the upper mold cavity 14. The top side of the lower mold base 11 contacts the bottom end of the lower mold cavity 12. The upper mold cavity 14 and the lower mold cavity... A T-plate 16 is provided on one side of each of the upper and lower mold cavities 14 and 12. One side of each cavity is fixedly connected to one end of the T-plate 16. A positioning plate 17 is provided on the inner wall of the T-plate 16, and the inner wall of the T-plate 16 is through-engaged with the protrusion of the positioning plate 17. A movable arm 18 is provided on one side of the middle of the positioning plate 17, and the middle side of the positioning plate 17 is rotatably connected to one end of the movable arm 18. A connecting plate 19 is provided on the other end of the movable arm 18, and the other end of the movable arm 18 is rotatably connected to the inner side of one end of the connecting plate 19. The internal part is equipped with a spring 113. The internal part of the connecting plate 19 is fixedly connected to the bottom end of the spring 113. The top end of the spring 113 is equipped with a sub-block 110, and the top end of the spring 113 is fixedly connected to the bottom end of the sub-block 110. The inclined surface of the sub-block 110 is equipped with a mother block 111, and the inclined surface of the sub-block 110 is slidably engaged with the inclined surface of the mother block 111. The top end of the mother block 111 is equipped with a rectangular plate 112, and the top end of the mother block 111 is fixedly connected to the bottom side of the rectangular plate 112. One end of the inner wall of the rectangular plate 112 is equipped with... The guide plate 114 has one end of the inner wall of the rectangular plate 112 slidably connected to the outer side of the guide plate 114. One end of the guide plate 114 is fixedly connected to the inner wall of the lower mold base 11 and the upper mold base 15 respectively. An inner plate 115 is provided on one side of the rectangular plate 112, and one side of the rectangular plate 112 contacts one side of the inner plate 115. The outer side of the inner plate 115 is slidably connected to the inner wall of the upper mold base 15 and the lower mold base 11 respectively. A push rod 116 is provided at the middle end of the connecting plate 19, and one end of the push rod 116 is fixedly connected to the middle end of the connecting plate 19.

[0029] In this embodiment, the easily replaceable instrument base mold uses a lower mold base 11 and an upper mold base 15 as the main frame. The top side of the lower mold base 11 is fixedly connected to the lower mold cavity 12, while the bottom side of the upper mold base 15 is fixed to the upper mold cavity 14. The upper mold cavity 14 and the lower mold cavity 12 are radially aligned, and a T-plate 16 is installed on one side of both the upper mold cavity 14 and the lower mold cavity 12. The components on the inner walls of the upper mold base 15 and the lower mold base 11 are identical. Taking the components on the inner wall of the lower mold base 11 as an example, two positioning plates 17 are installed on the inner wall of the lower mold base 11. Each positioning plate 17 has a protrusion and two protrusions. Both positioning plates 17 are connected to a movable arm 18, which is in an inclined state. The other end of the movable arm 18 rotates inside one end of a connecting plate 19. The connecting plate 19 is located between the two positioning plates 17. Then, by applying an external force to one side to the push rod 116, the connecting plate 19 moves, and the arm of the movable arm 18 is extended, thereby increasing the distance between the two positioning plates 17. At the same time, the positioning plate 17 will pass through the T plate 16 under the push of the external force. After passing through the T plate 16, the lower mold cavity 12 and the lower mold base 11 can be structurally connected. In addition, the upper mold base 15 and the upper mold cavity 14 are also connected in this way. Since the mold cavity and the mold base adopt a modular positioning structure, when it is necessary to replace the instrument bottom cover mold of different specifications, it is not necessary to disassemble the entire mold frame. Only by controlling the locking state of the positioning plate 17 and the T plate 16 through the push rod 116, the mold cavity can be quickly replaced, effectively shortening the mold replacement time.

[0030] Taking the lower mold base 11 as an example, a rectangular plate 112 is designed on the inner wall of the lower mold base 11. Multiple mother blocks 111 are designed along the plane of the rectangular plate 112. The mother blocks 111 are triangular in shape, and the inclined surfaces of the mother blocks 111 contact the inclined surfaces of the daughter blocks 110. The daughter blocks 110 are also triangular in shape and are installed inside the connecting plate 19. Two daughter blocks 110 are sufficient to engage with the mother blocks 111. A spring 113 is located between the daughter blocks 110 and the connecting plate 19, which in turn pushes the connecting plate 19... During the process, the inclined surface of the sub-block 110 slides relative to the inclined surface of the mother block 111. The sub-block 110 will retract into the connecting plate 19 and compress the spring 113. When the sub-block 110 slides to the gap between the adjacent mother blocks 111, the elastic force of the spring 113 will push the sub-block 110 to reset, so that it re-engages with the mother block 111 to form a positioning. This makes the advancement process of the connecting plate 19 present a stepped positioning effect, effectively preventing the connecting plate 19 from retreating after being subjected to force, and ensuring that the fixing effect of the positioning plate 17 is in a stable state.

[0031] Taking the lower mold base 11 as an example, an inner plate 115 is designed on the inner wall of the lower mold base 11, located on the top side of the rectangular plate 112. The inner plate 115 is located between the lower mold base 11 and the rectangular plate 112. By pulling the inner plate 115 out from the lower mold base 11, a gap is created between the rectangular plate 112 and the lower mold base 11. When the connecting plate 19 is reset, the rectangular plate 112 cannot retain its position, making the reset process easier. At the same time, a guide plate 114 is passed through the inner wall of one end of the rectangular plate 112. When the rectangular plate 112 is not pressed by the inner plate 115, the movement path of the guide plate 114 is restricted, avoiding skewing.

[0032] Example 2

[0033] like Figure 3 As shown, the limiting mechanism 2 includes a fixed plate 21. A connecting rod 22 is provided on one side of the fixed plate 21. One side of the fixed plate 21 is fixedly connected to one end of the connecting rod 22. The outer side of one end of the connecting rod 22 is slidably connected to the inner wall of the positioning plate 17. A second spring 23 is provided on one side of the positioning plate 17. One side of the positioning plate 17 is fixedly connected to one end of the second spring 23. The other end of the second spring 23 is fixedly connected to one side of the fixed plate 21.

[0034] In this embodiment, a fixing plate 21 is installed on the inner wall of both the upper mold base 15 and the lower mold base 11. A connecting rod 22 is designed on one side of the fixing plate 21, and the outer side of one end of the connecting rod 22 is located on the inner wall of the positioning plate 17. This allows the positioning plate 17 to move along the designed path when it moves, preventing the positioning plate 17 from tilting due to uneven force and ensuring that both ends of the positioning plate 17 remain parallel. A second spring 23 is installed between the positioning plate 17 and the fixing plate 21. When the positioning plate 17 moves under the push of the movable arm 18, the second spring 23 is compressed. When the external force driving the positioning plate 17 disappears, the rebound force of the second spring 23 will assist the movable arm 18 in driving the positioning plate 17 to quickly reset.

[0035] Working principle:

[0036] like Figures 1-6As shown, by applying an external force to one side to the push rod 116, the connecting plate 19 moves, and the arm of the movable arm 18 extends, thereby increasing the distance between the two positioning plates 17. Simultaneously, the positioning plate 17, pushed by the external force, passes through the T-plate 16. After passing through the T-plate 16, the lower mold cavity 12 and the lower mold base 11 are structurally connected. Furthermore, the upper mold base 15 and the upper mold cavity 14 are also connected in this way. Simultaneously, by controlling the locking state of the positioning plate 17 and the T-plate 16 through the push rod 116, the mold cavity can be quickly changed. Then, the connecting plate 19 is moved... During the pushing process of the connecting plate 19, the inclined surface of the sub-block 110 slides relative to the inclined surface of the mother block 111. The sub-block 110 will retract into the connecting plate 19 and compress the spring 113. When the sub-block 110 slides to the gap between the adjacent mother blocks 111, the elastic force of the spring 113 will push the sub-block 110 to reset, so that it re-engages with the mother block 111 to form a positioning. This makes the pushing process of the connecting plate 19 present a stepped positioning effect, effectively preventing the connecting plate 19 from retreating after being subjected to force, and ensuring that the fixing effect of the positioning plate 17 is in a stable state.

[0037] By installing fixing plates 21 on the inner walls of both the upper mold base 15 and the lower mold base 11, and designing a connecting rod 22 on one side of the fixing plate 21, with one end of the connecting rod 22 located on the inner wall of the positioning plate 17, the positioning plate 17 can move along the designed path when it moves. A second spring 23 is installed between the positioning plate 17 and the fixing plate 21. When the external force driving the positioning plate 17 disappears, the second spring 23 will reset the positioning plate 17.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
