Detailed Implementation

[0020] This utility model provides, for example Figures 1-3 The mold shown is easy to demold, including a lower mold 1 and an upper mold 2 above the lower mold 1. The lower mold 1 is fixedly installed on a workbench, and a control component (not shown in the figure) is provided on the workbench to drive the upper mold 2 to move up and down. The control component includes structures such as an electric push rod. The fixed end of the electric push rod is fixedly connected to the workbench, and the upper mold 2 is fixedly connected to the telescopic end of the electric push rod. The electric push rod and the like are connected to the factory's power supply.

[0021] The lower mold 1 and the upper mold 2 are fixed together by a locking component 16, which includes a positioning pin, a positioning plate and other structures, and can connect and lock the lower mold 1 and the upper mold 2.

[0022] The top of the lower mold 1 has a groove 13, and a molding seat 3 is provided inside the groove 13. A molding cavity 5 is provided on the molding seat 3. The upper mold 2 is provided with an injection channel that cooperates with the mold cavity 17. A rubber ring 4 is fixedly connected to the outside of the molding seat 3. The rubber ring 4 is fixedly connected to the inner wall of the groove 13. The rubber ring 4 is made of rubber and has a certain deformation capability.

[0023] To fix the position of the molding base 3, a fixing ring 6 is fixedly connected to the outside of the molding base 3, and the fixing ring 6 is fixedly connected to the bottom of the rubber ring 4. The fixing ring 6 can be made of stainless steel, but is not limited to stainless steel.

[0024] Furthermore, when the upper mold 2 moves downwards and fits against the top of the rubber ring 4, there is a certain gap between the lower mold 1 and the upper mold 2.

[0025] The bottom end of the upper mold 2 has multiple mounting grooves 7, which are evenly distributed around the molding base 3. An electric push rod 8 is fixedly connected inside each mounting groove 7. A through groove 9 is provided on the rubber ring 4 through which the telescopic end of the electric push rod 8 passes. The inner diameter of the through groove 9 is larger than the outer diameter of the telescopic end of the electric push rod 8, ensuring that vibration and deformation of the rubber ring 4 will not affect the electric push rod 8. The telescopic end of the electric push rod 8 abuts against the fixing ring 6.

[0026] Specifically, when the telescopic ends of multiple electric push rods 8 are controlled to retract synchronously and into the mounting groove 7, the fixing ring 6 loses its compressive force, and the rubber ring 4 can swing and deform, thereby allowing the molding seat 3 to swing. When the telescopic ends of multiple electric push rods 8 are controlled to extend synchronously and pass through the through groove 9 to abut against the fixing ring 6, the telescopic ends of multiple electric push rods 8 abut against the fixing ring 6 from different positions. At this time, the fixing ring 6 cannot swing, thus achieving the positioning of the molding seat 3.

[0027] At this time, the top of the rubber ring 4 is still attached to the bottom of the upper mold 2, which does not affect the molding operation.

[0028] Furthermore, an electric push rod 8 can be installed below the fixed ring 6. The fixed end of the electric push rod 8 is fixed to the bottom of the groove 13, while the telescopic end of the electric push rod 8 abuts against the fixed ring 6. At this time, the telescopic end of the electric push rod 8 extends out, and the upper and lower electric push rods 8 cooperate to clamp and fix the fixed ring 6, further ensuring the stability of the fixed ring 6. Adjustments can be made according to the specific usage.

[0029] A vibrator 10 is fixedly connected to the bottom of the molding base 3. It is powered on and operates. Heat dissipation grooves, filters, etc. can be installed on the lower mold 1 to ensure heat dissipation of the vibrator 10.

[0030] In actual use, control the upper mold 2 to move downward and fit against the top of the rubber ring 4, and keep it still. Use the locking part 16 to connect and lock the lower mold 1 and the upper mold 2. Then control the telescopic ends of multiple electric push rods 8 to retract synchronously and retract into the interior of the mounting groove 7. At this time, the fixing ring 6 loses its squeezing effect, and the rubber ring 4 can swing and deform, so that the molding seat 3 can swing and inject molten material into the molding cavity 5 through the liquid injection channel.

[0031] At this time, the vibrator 10 is activated, causing the molding seat 3 to shake, eliminating shrinkage cavities and depressions, while also accelerating the filling speed of the molten material, improving production efficiency and reducing energy consumption.

[0032] Furthermore, the vibration frequency of the vibrator 10 is limited, and the top of the rubber ring 4 always adheres to the bottom of the upper mold 2, without affecting the molding operation.

[0033] After the molten material is injected, the telescopic ends of multiple electric push rods 8 are extended synchronously and pass through the through groove 9 to abut against the fixed ring 6. At this time, the fixed ring 6 cannot swing, thus positioning the molding seat 3 and ensuring stable molding.

[0034] After molding is completed, the telescopic ends of multiple electric push rods 8 are retracted synchronously and returned to the interior of the mounting groove 7. At this time, the fixing ring 6 loses its squeezing effect, the rubber ring 4 can swing and deform, so that the molding seat 3 can swing; the vibrator 10 is started to make the molding seat 3 shake, which helps the molded part to separate from the molding seat 3, making it easier for the molded part to be removed from the molding cavity 5, and facilitating demolding.

[0035] This utility model, by setting up a molding seat 3, a rubber ring 4 and other structures, allows the molding seat 3 to switch between swinging and positioning, assisting in the separation of the molded part from the molding seat 3, reducing the workload of operators, eliminating shrinkage cavities and depressions, and accelerating the filling speed of molten material, ensuring production efficiency and reducing energy consumption, and improving the utilization efficiency of the mold.

[0036] To improve demolding efficiency, a top groove 11 is provided at the bottom of the molding base 3. The molding cavity 5 is connected to the groove 13 through the top groove 11. A push rod 12 is slidably arranged inside the top groove 11.

[0037] The push rod 12 includes a first hard section 1201, a rubber section 1202, and a second hard section 1203. The rubber section 1202 is fixedly connected between the first hard section 1201 and the second hard section 1203. The first hard section 1201 is located inside the top groove 11. The first hard section 1201 and the second hard section 1203 can be made of stainless steel, but are not limited to stainless steel. The rubber section 1202 is made of rubber with a certain hardness. The rubber section 1202 corresponds to the bottom end of the molding seat 3.

[0038] The bottom end of the lower mold 1 is provided with a groove 14, which communicates with the groove 13. A slide plate 15 is slidably disposed inside the groove 14, and the bottom end of the second rigid section 1203 is fixedly connected to the slide plate 15. An electric push rod is installed on the worktable. The fixed end of the electric push rod is fixedly connected to the worktable, and the slide plate 15 is fixedly connected to the telescopic end of the electric push rod (not shown in the figure).

[0039] In actual use, the slide plate 15 moves downward inside the slide groove 14, at which point the top of the first rigid section 1201 is flush with the top of the top groove 11 (refer to...). Figure 3 This does not affect the molding operation. When the vibrator 10 is activated to make the molding seat 3 vibrate, the rubber segment 1202 can adapt to deformation without affecting the vibration of the molding seat 3.

[0040] When the vibrator 10 is restarted, after the molded part is separated from the molded seat 3, the slide plate 15 is controlled to move upward inside the slide groove 14, which drives the ejector rod 12 to move upward, pushing the molded part upward and speeding up demolding.
