Description

Technical Field

[0001] The utility model relates to the technical field of correction of injection molded parts, in particular to a cooling tool for correction of precision injection molded parts. Background Art

[0002] Injection molded part correction is the process of physically modifying the shape of an injection molded part. In the design and manufacture of small injection molded parts, complex structures above thick bottom walls often occur in products that require good support and complex geometries, such as lock components, electronic equipment brackets, and automotive parts. These injection molded parts may be corrected manually, which requires the operator to have high skills and experience. Cooling the injection molded part after correction is an important step to ensure the stability of the correction effect. For such injection molded parts, some factories use air cooling for heat dissipation. When the complex structure on the top of the injection molded part is cooled by airflow, the fixed airflow direction may lead to uneven internal heat dissipation. The thick bottom wall, if cooled simply by air, would take a long time and be inconvenient to use. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 5 The top of the limit seat 11 is provided with two cooling grooves 111, and the interior of the cooling groove 111 is slidably connected to a placement plate 12. The interior of the limit seat 11 is connected to a cooling pipe 13, and four flow grooves 113 are provided inside the limit seat 11. The top of the flow groove 113 is connected to the adjacent cooling grooves 111, and the outer wall of the cooling pipe 13 is connected with a plurality of connecting shells 132. One end of the connecting shell 132 is connected to the adjacent flow groove 113. Cooling water tanks 14 for cooling the cooling pipe 13 are fixedly embedded on both sides of the limit seat 11. Two limit frames 16 are fixedly connected to the rear side of the limit seat 11. The interior of the limit frame 16 is slidably connected to an exhaust pipe 161. The top of the limit seat 11 is provided with an air supply mechanism 17 for supplying and regulating air to the two exhaust pipes 161.

[0023] Specifically, the cooling pipe 13 and the cooling tank 111 are connected through the circulation groove 113 and the connecting shell 132, the placement plate 12 is used to place the injection molded parts, and the rotation of the exhaust pipe 161 is used to blow air at different angles to cool the top of the injection molded parts, and the electric push rod 123 is started to lift the placement plate 12, and the plastic cylinder 131 is squeezed to supply the moisture in the cooling pipe 13 into the cooling tank 111. The height of the cooling water in the cooling tank 111 can also be adjusted, and the thicker bottom plate of the injection molded parts can be water-cooled, which is convenient to use.

[0024] Example 1

[0025] like Figure 1-3 As shown, in this embodiment, a limiting groove 112 is provided inside the limiting seat 11, and a connecting plate 122 is slidably connected between the two inner walls of the limiting groove 112. Two round rods 124 are fixedly connected to the top of the connecting plate 122. The top of the round rod 124 passes through the limiting seat 11 and is fixedly connected to the bottom of the adjacent placement plate 12. Two electric push rods 123 are fixedly connected to the inner bottom surface of the limiting groove 112. The output end of the electric push rod 123 is fixedly connected to the bottom of the connecting plate 122. The placement plate 12 is movably engaged with the inner bottom surface of the cooling groove 111. A plurality of tooth plates 121 are equidistantly fixedly connected to the top of the placement plate 12. Both ends of the limiting seat 11 are connected to a water pipe 141. The two water pipes 141 are connected to the cooling circulation pipeline through the pipeline. The cooling pipe 13 passes through the two cooling water tanks 14.

[0026] In this embodiment, the limiting groove 112 limits the sliding of the connecting plate 122, and the limiting of the two round rods 124 by the connecting plate 122 limits the sliding of the placing plate 12. The two electric push rods 123 are started synchronously to synchronously adjust the height of the two placing plates 12 and the injection molded parts therein. When the placing plate 12 is engaged with the inner bottom surface of the cooling groove 111, the top of the two adjacent circulation grooves 113 is blocked. When the placing plate 12 is separated from the inner bottom surface of the cooling groove 111, the water inside the cooling pipe 13 can enter the cooling groove 111 through the connecting shell 132 and the circulation groove 113. After the placing plate 12 is lifted, the excess water on the top of the placing plate 12 flows back to the cooling groove 111 through the gap between the multiple tooth plates 121, and the cooling pipe 13 and the water inside it are cooled by the circulating cooling water inside the cooling water tank 14. The cooling pipe 13 passes through the cooling water tank 14 but does not directly contact the water inside the cooling water tank 14.

[0027] like Figure 1-2As shown, in this embodiment, a plastic tube 131 is connected to the outer wall of the cooling tube 13, a mounting plate 114 is fixedly sleeved between the outer walls of the limit seat 11, and the top of the mounting plate 114 is slidably connected to a clamping plate 115 for squeezing the plastic tube 131, and the top of the mounting plate 114 is rotatably connected to a screw rod 116, which passes through the clamping plate 115 and is screwed together with it, and two organic glass blocks 15 are fixedly embedded in the top of the limit seat 11.

[0028] During specific implementation, the limiting seat 11 is fixed as a whole by means of the mounting plate 114 and the bolts. When the placing plate 12 is separated from the bottom of the cooling groove 111, the screw rod 116 is rotated to drive the clamping plate 115 to move, and the clamping plate 115 squeezes the plastic tube 131, and squeezes the water inside the cooling tube 13 into the circulation groove 113 through the connecting shell 132, and enters the cooling groove 111 through the top of the circulation groove 113. The height of the water inside the cooling groove 111 can be adjusted, and the internal situation of the cooling groove 111 can be conveniently observed through the setting of the organic glass block 15.

[0029] Example 2

[0030] On the basis of the first embodiment, in order to be able to drive the exhaust pipe 161 to continuously rotate and change the air outlet direction, the internal groove structure on the top of the injection molded part can be fully cooled.

[0031] like Figure 4-5 As shown, in this embodiment, the air supply mechanism 17 includes a support base 171 fixedly connected to the outer wall of the rear side of the limiting seat 11, a fan 172 is fixedly connected to the top of the support base 171, a main pipe 173 is fixedly connected to the top of the support base 171, the air outlet end of the fan 172 is connected to the main pipe 173, and two branch pipes 174 are connected on the outer wall of the main pipe 173. The bottom end of the branch pipe 174 is connected to the adjacent exhaust pipe 161 through a rotating joint 175. Two mounting brackets 163 are symmetrically fixedly connected to the outer wall of the rear side of the limiting seat 11. The top of the mounting bracket 163 is fixedly connected to the outer wall of the adjacent limiting bracket 16, and the exhaust pipe 16 1 is fixedly connected with a ferrule 162 on the outer wall, and an arc-shaped slider 166 is fixedly connected to the outer wall of the ferrule 162. The arc-shaped slider 166 is slidably connected to the inside of the limit frame 16. The top and bottom ends of the arc-shaped slider 166 are rotatably connected with balls 167. The top of the limit frame 16 is rotatably connected with a fixing ring 164. The ferrule 162 is fixedly connected to the fixing ring 164. The inner wall of the fixing ring 164 is fixedly sleeved with an outer gear ring 165. The top of the mounting frame 163 is fixedly embedded with a second motor 176. The output end of the second motor 176 is fixedly sleeved with a second gear 177. The second gear 177 is meshed with the outer gear ring 165.

[0032] During the specific implementation, the support base 171 is used to fix the fan 172 and the main pipe 173, and the fan 172 is started to blow the air flow through the main pipe 173 into the two branch pipes 174. The setting of the rotary joint 175 can meet the rotation connection requirements of the branch pipe 174 and the exhaust pipe 161. The air flow enters the exhaust pipe 161 and continuously changes the ejection direction and position of the air flow as the bottom end of the exhaust pipe 161 changes. The rotary joint 175 can adopt a pneumatic rotary joint, which is a conventional existing technical means. The limiting frame 16 limits the arc-shaped slider 166 to achieve sliding limitation of the sleeve 162 and the exhaust pipe 161. The ball 167 reduces the friction between the arc-shaped slider 166 and the limiting frame 16. The starting motor 2 176 drives the gear 2 177 to rotate. The transmission of the gear 2 177 and the outer gear ring 165 drives the fixed ring 164, the sleeve 162 and the exhaust pipe 161 to rotate, so that the bottom end of the exhaust pipe 161 continuously changes position along the trajectory of the limiting frame 16, so that the air outlet direction continuously changes.

[0033] It will be apparent 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 characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
