Description

Technical Field

[0001] This utility model relates to the field of automated scissor-foot mold technology, and in particular to an integrated cooling mechanism for a 16+32 cavity automated scissor-foot mold. Background Technology

[0002] Scissor-switch mechanism is an essential component of a pen keyboard, generally consisting of an inner scissor and an outer scissor. The inner scissor has pivots on its front and rear outer walls, while the outer scissor has corresponding pivot holes on its front and rear inner walls. The free end of the pivot has a cut-off wedge-shaped surface facing the pivot hole. The pivot hole is formed by a groove with an arc-shaped cross-section coaxially connected to a circular blind hole. The pivot passes through the groove axially before being inserted into the circular blind hole. When the pivots on the front and rear outer walls of the inner scissor are respectively inserted into the pivot holes on the front and rear inner walls of the outer scissor, the scissor mechanism is assembled.

[0003] To facilitate subsequent assembly, existing scissor-foot molds typically produce components consisting of inner shears, outer shears, and sprue heads. These components include regularly arranged inner and outer shears connected by sprue heads. To improve production efficiency, scissor-foot molds simultaneously injection mold multiple components, producing multiple components in a single injection using a multi-cavity mold structure. A 16+32 cavity scissor-foot automated mold refers to a mold with 16 sprue head cavities and 32 inner and outer shear cavities.

[0004] While existing scissor-type molds can effectively improve production efficiency through a multi-cavity injection molding structure, the excessive number of cavities after injection molding results in a slow cooling rate, severely impacting injection efficiency.

[0005] Therefore, it is necessary to provide an integrated cooling mechanism for automated molds with 16+32 cavity scissor feet to solve the above-mentioned technical problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] refer to Figures 1 to 5 This utility model provides a 16+32 cavity scissor-foot automated mold integrated cooling mechanism, comprising: an upper mold 2 with multiple cavities and a lower mold 1. The bottom of the lower mold 1 is provided with multiple rectangular connecting grooves 24. The cavities of the lower mold 1 are located inside the connecting grooves 24. The connecting grooves 24 are slidably connected to the inner wall of a cooling box 11. The bottom of the cooling box 11 is connected to the top of a fixed base 3. The two opposite outer sides of the cooling box 11 are respectively provided with a water inlet and a water outlet. The water inlet is connected to the peripheral side of a water inlet branch pipe 14 through a water inlet pipe 13 and a water inlet solenoid valve 12. One end of the inlet branch pipe 14 is connected to the periphery of the main inlet pipe 15. One end of the main inlet pipe 15 is connected to the external water pipe 16. The outlet is connected to the periphery of the outlet branch pipe 19 via the outlet pipe 18 and the outlet solenoid valve 17. One end of the outlet branch pipe 19 is connected to the periphery of the main outlet pipe 20. One end of the main outlet pipe 20 is connected to one end of the recovery pipe 21. The other end of the recovery pipe 21 is connected to the recovery box. The main inlet pipe 15 and the main outlet pipe 20 are placed opposite each other on the top of the fixed base 3. The inlet solenoid valve 12 and the outlet solenoid valve 17 are electrically connected to the controller.

[0026] It should be noted that the scissor-foot automated mold is a single mold with a multi-cavity structure. The 16+32 cavity scissor-foot automated mold refers to a mold with 16 material head cavities and 32 inner and outer shear cavities. The cavities of the lower mold 1 are located inside the connecting groove 24, which means that an inner shear + outer shear + material head cavity is located inside the connecting groove 24.

[0027] Before injection molding, the cooling box 11 is slidably connected to the connecting groove 24, leaving a gap between the bottom of the connecting groove 24 and the bottom of the cooling box 11. Then, the external water pipe 16 and the water inlet solenoid valve 12 are opened, and cooling water is injected into the gap between the cooling box 11 and the connecting groove 24 through the main water inlet pipe 15, the branch water inlet pipe 14, and the water inlet pipe 13. During the injection molding operation, the cooling water can absorb heat from the high-temperature material injected into the mold cavity, accelerating the cooling efficiency of the high-temperature material, allowing it to cool down and stabilize quickly, effectively improving the injection efficiency of the mold. By setting up a recovery pipe 21, after the cooling water has been used for a period of time, the outlet solenoid valve 17 is opened, and the cooled water that has absorbed heat enters the recovery pipe 21 through the outlet pipe 18, the outlet branch pipe 19 and the outlet main pipe 20, and is finally discharged into the recovery box. After discharge, new cooling water is injected into the cooling box 11 by opening the external water pipe 16 and the inlet solenoid valve 12. By replacing the cooling water, the temperature of the cooling water is prevented from rising after a period of use, which would affect the heat absorption efficiency of the mold cavity and thus the cooling efficiency of the high-temperature raw materials.

[0028] With the above structure, each group of mold cavities is cooled individually through a cooling box 11, which effectively improves the cooling efficiency of the mold cavities and prevents the cooling speed from being too slow after injection molding due to too many mold cavities, which would seriously affect the injection molding efficiency.

[0029] In the embodiments of this utility model, reference is made to Figure 3 As shown, a rectangular sealing gasket 22 is bonded to the top of the cooling box 11, and the sealing gasket 22 is made of rubber.

[0030] It should be noted that the rubber sealing gasket 22 effectively improves the sealing performance at the connection between the top of the cooling box 11 and the connecting groove 24 by utilizing the elasticity of the sealing gasket 22.

[0031] In the embodiments of this utility model, reference is made to Figure 3 As shown, the edge of the fixed base 3 is provided with a rectangular support frame 4, the cooling box 11 is located inside the support frame 4, and the top of the support frame 4 is movably connected to the bottom of the lower mold 1.

[0032] In the embodiments of this utility model, reference is made to Figure 3 , Figure 5 As shown, the top of the support frame 4 is provided with multiple fixing grooves 10, and the bottom of the lower mold 1 is provided with a fixing shaft 25 that cooperates with the fixing grooves 10.

[0033] It should be noted that by setting the support frame 4, the lower mold 1 can be connected to the support frame 4, which improves the stability of the lower mold 1 when it is placed. By setting the fixing groove 10 and the fixing shaft 25, the stability and convenience of the connection between the lower mold 1 and the support frame 4 are improved, and the lower mold 1 can be easily removed from the fixing seat 3 in case of problems.

[0034] In the embodiments of this utility model, reference is made to Figure 5 As shown, the bottom of the lower mold 1 below the center of the cavity is provided with multiple conductive grooves 26.

[0035] It should be noted that by setting the conduction groove 26, the thickness of the bottom of the mold cavity can be reduced without affecting the normal use of the lower mold 1, so that the cooling water in the cooling box 11 can better absorb heat.

[0036] In the embodiments of this utility model, reference is made to Figure 1 , Figure 2 As shown, a rectangular cooling frame 5 is installed on the outer surface of the lower mold 1. The cooling frame 5 has a hollow structure. The two opposite outer sides of the cooling frame 5 are respectively provided with an upper water inlet and an upper water outlet. The upper water inlet is connected to the peripheral side of the upper water inlet pipe 7 and the upper water inlet main pipe 15 through an upper water inlet solenoid valve 6. The upper water outlet is connected to the peripheral side of the upper water outlet pipe 9 and the upper water outlet main pipe 20 through an upper water outlet solenoid valve 8.

[0037] It should be noted that by setting the cooling frame 5, heat can be absorbed from the side of the lower mold 1. In conjunction with the cooling box 11, the heat absorption efficiency of the lower mold 1 is improved, and the cooling of the high-temperature raw material is accelerated.

[0038] In the embodiments of this utility model, reference is made to Figure 4 As shown, a temperature sensor 23 is installed at the bottom of the interior of the cooling box 11, and the temperature sensor 23 is electrically connected to the controller.

[0039] It should be noted that by setting temperature sensor 23, the water temperature of the cooling water in the cooling box 11 can be monitored in real time. The inlet solenoid valve 12 and outlet solenoid valve 17 can be opened according to the water temperature to replace the cooling water. The high-temperature water can be replaced with low-temperature water in a timely manner, which effectively improves the cooling efficiency.

[0040] The working principle of the 16+32 cavity scissor-foot automated mold integrated cooling mechanism provided by this utility model is as follows:

[0041] Cooling water is injected into the gap between the cooling box 11 and the connecting groove 24 through the main water inlet pipe 15, the branch water inlet pipe 14, and the water inlet pipe 13. During the injection molding operation, the cooling water can absorb heat from the high-temperature raw material injected into the mold cavity, accelerate the cooling efficiency of the high-temperature raw material, and make it cool down and stabilize quickly, effectively improving the injection efficiency of the mold. By setting up the recovery pipe 21, after the cooling water has been used for a period of time, the outlet solenoid valve 17 is opened, and the cooled water after absorbing heat enters the recovery pipe 21 through the outlet pipe 18, the branch water outlet pipe 19, and the main water outlet pipe 20, and is finally discharged into the recovery box. After discharge, new cooling water is injected into the cooling box 11 by opening the external water pipe 16 and the water inlet solenoid valve 12. By replacing the cooling water, the temperature of the cooling water is prevented from rising after a period of use, which would affect the subsequent heat absorption efficiency of the mold cavity and thus affect the cooling efficiency of the high-temperature raw material.

[0042] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
