Description

Technical Field

[0001] The utility model relates to the technical field of communication electronic workpiece processing, in particular to an exhaust structure for communication electronic precision moulds. Background Art

[0002] In precision molds for communication electronics, the design of the exhaust structure is crucial. If the air in the mold cavity and the high-temperature volatilization of the plastic are not discharged in time, there will be bubbles, silver streaks or clouds on the product after it is formed. Good exhaust can ensure that the plastic flows more smoothly in the mold and avoid mixing of gas and molten plastic, thereby reducing product defects and improving product quality. Some molds use breathable plugs for exhaust, which is suitable for situations where exhaust grooves are not allowed in certain parts. Breathable steel can be used as an insert to achieve exhaust. Breathable steel has a mesh structure that allows gas to pass through. However, in the working environment of the mold, the breathable plug will gradually wear and may be blocked. The exhaust plug needs to be checked and replaced regularly. Some exhaust plugs are fixed with threads, which may become loose in an impact working environment. Some exhaust plugs are fixed by welding and bonding. The removal of welded exhaust plugs requires cutting, which is more troublesome. After the removal of bonded exhaust plugs, the installation groove needs to be cleaned. The replacement of exhaust plugs is more time-consuming and inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figures 1 to 5 In an embodiment of the utility model, an exhaust structure for a precision mold for communication electronics comprises an exhaust mechanism 10, the exhaust mechanism 10 comprises a mother mold body 11 and an exhaust base 14, two limit shells 143 are symmetrically fixedly connected to the outer wall of the exhaust base 14, a mold core body 12 is fixedly embedded in the mother mold body 11, an exhaust branch groove 121 is provided in the mold core body 12, a mounting groove 122 for limiting the exhaust base 14 is provided on the top of the mold core body 12, the mounting groove 122 is communicated with the exhaust branch groove 121, a breathable mesh plate 141 is fixedly connected to the top of the exhaust base 14, two limit blocks 123 are slidably connected between the inner walls of the mounting groove 122, the limit blocks 123 are movably engaged with adjacent limit shells 143, and a control module 15 for controlling the adjacent limit blocks 123 is arranged inside the two limit shells 143, and an exhaust main groove 13 is provided inside the mother mold body 11.

[0022] Specifically, the exhaust base 14 and the air permeable mesh plate 141 are both made of stainless steel. By fixing two limit shells 143 on the outer wall of the exhaust base 14, the limit shell 143 can be aligned with the installation groove 122 and then snapped in. The limit shell 143 and the limit block 123 are quickly snapped into place, and the installation is convenient. The exhaust base 14 cooperates with the air permeable mesh plate 141 to limit the top of the exhaust branch groove 121 and exhaust. The stamping operation of the mold will not loosen the connection. The air permeable mesh plate 141 is impacted by sharp objects such as a screwdriver, so that the push rod 152 moves to push out the limit block 123, and the exhaust base 14 can be quickly disassembled for easy use. The exhaust main groove 13 is used to dock with multiple exhaust branch grooves 121, and the gases in the multiple exhaust branch grooves 121 are merged into the exhaust main groove 13 and discharged uniformly.

[0023] Embodiment 1

[0024] like Figure 1-2 As shown, in this embodiment, two slide grooves 1221 are provided on the inner wall of the installation groove 122, and the limit block 123 is slidably connected to the inside of the adjacent slide groove 1221. A return spring 124 is fixedly connected between one end of the limit block 123 and the slide groove 1221, and the other end of the limit block 123 is arc-shaped. A docking groove 144 is provided on one side of the limit shell 143, and the limit block 123 can be movably engaged with the adjacent docking groove 144.

[0025] In this embodiment, the limit block 123 is slidably limited by the slide groove 1221. When the exhaust base 14 and the breathable mesh plate 141 move down and are inserted into the installation groove 122, the bottom end of the limit shell 143 contacts the arc-shaped end surface of the limit block 123, and then the limit block 123 is moved to the inside of the slide groove 1221 to compress the reset spring 124. As the limit shell 143 continues to move downward, the limit block 123 is pushed by the reset spring 124 to be inserted into the docking groove 144 and connected with the limit shell 143, thereby quickly limiting the limit shell 143.

[0026] like Figure 3 As shown, in this embodiment, a reinforcement ring 142 is fixedly sleeved on the outer wall of the exhaust base 14 .

[0027] In specific implementation, when the mold is in operation, certain stress will be generated inside the installation groove 122, and the reinforcement ring 142 is used to strengthen the overall strength of the exhaust base 14, so that the exhaust base 14 and the air-permeable mesh plate 141 can better adapt to the installation environment.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, in order to separate the limiting block 123 from the limiting shell 143 from the outside, the exhaust base 14 can be quickly disassembled, and the installation groove 122 does not need to be cleaned.

[0030] like Figure 1-5 As shown, in the present embodiment, the regulating module 15 includes a limiting plate 151 fixedly connected between the two inner walls of the limiting shell 143, a push rod 152 is slidably connected inside the limiting plate 151, a return spring 153 is fixedly connected between the push rod 152 and the limiting plate 151, one end of the return spring 153 is fixedly connected to a mounting plate 154, a pull rope 158 is movably connected inside the limiting shell 143, a regulating block 157 is movably connected to the top of the limiting shell 143, the regulating block 157 is fixedly connected to the breathable mesh plate 141, the top end of the pull rope 158 passes through the limiting shell 143 and is fixedly connected to the adjacent regulating block 157, the bottom end of the pull rope 158 passes through the limiting shell 143 and is fixedly connected to the adjacent mounting plate 154, a card plate 155 is fixedly connected to the outer wall of the push rod 152, and a card plate 2 156 for limiting the card plate 155 is fixedly connected between the two inner walls of the limiting shell 143.

[0031] In a specific implementation, the push rod 152 is slidably limited by the limit plate 151, and the return spring 153 is used to drive the push rod 152 to remain in place. When the limit shell 143 is pulled out from the installation groove 122, the push rod 152 is moved, and the push rod 152 pushes the limit block 123 to push it out of the docking groove 144. After the limit block 123 is separated from the limit shell 143, the limit shell 143 can be moved upward for disassembly. When the damaged exhaust base 14 and the air permeable mesh plate 141 need to be replaced, the air permeable mesh plate 141 can be directly impacted with a sharp object such as a screwdriver to deform the air permeable mesh plate 141. 41 pulls the two regulating blocks 157 to move and separate from the limit shell 143. The regulating block 157 pulls the mounting plate 154 and the limit plate 151 to move through the pull rope 158 to drive the push rod 152. The pull rope 158 can be made of graphite packing rope, which has the characteristics of high temperature and high pressure resistance. It is often used for sealing packing and can withstand flexible high temperature environment. The moving range of the push rod 152 is limited by the clamping plate 155 and the clamping plate 2 156, so that the push rod 152 will not move to the outside of the docking groove 144 and exceed the outer wall of the limit shell 143, thereby preventing the push rod 152 from contacting the inner wall of the mounting groove 122 and affecting the disassembly of the limit shell 143.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
