Description

Technical Field

[0001] This invention belongs to the field of silicone mold technology, specifically a silicone mold component. Background Technology

[0002] Silicone molds are special molds used to make handicrafts. According to their properties, silicone mold raw materials can be divided into ordinary silicone and weather silicone. Because silicone molds have low clamping ability, or the gap between the upper and lower molds increases after the mold has been used for a long time, silicone products made from silicone molds are prone to having more burrs at the parting line. In order to ensure the aesthetics and performance of the product, the burrs on the parting line must be cleaned.

[0003] Currently, using flash-free molds can minimize the amount of burrs on silicone products. However, the purchase cost of flash-free molds is relatively high, increasing the burden on enterprises. Therefore, existing enterprises generally use handheld equipment to clean the burrs on products made from silicone molds, which can effectively reduce cost pressure. However, when polishing manually with special tools, if the hand is unstable, it is easy to over-polish, causing deviations in the size of the silicone products. At the same time, in order to ensure the yield rate, polishing operations require personnel with many years of experience, and the polishing process must be very careful, which leads to increased labor costs and low polishing efficiency.

[0004] In view of this, the present invention provides a silicone mold assembly to solve the above-mentioned technical problems. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and solve the problems of over-polishing when manually polishing the rough edges of silicone products, which can lead to dimensional deviations in the silicone products, and the increased labor costs due to the need for experienced personnel to operate the equipment, this invention proposes a silicone mold assembly.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] The silicone mold assembly of the present invention includes:

[0008] Lower mold;

[0009] The upper mold and the lower mold are symmetrically distributed vertically.

[0010] The mold cavities are respectively disposed in the upper mold and the lower mold;

[0011] Also includes:

[0012] A polishing unit is disposed inside the upper mold, and the polishing units are symmetrically distributed with the center line of the upper mold as a reference line.

[0013] A control component is disposed inside the polishing unit;

[0014] A polishing assembly is disposed inside the control assembly, the control assembly being used to drive the polishing assembly to move;

[0015] The polishing component is used to polish the rough edges of the parting line on silicone products.

[0016] Preferably, the polishing unit includes:

[0017] A support frame, which is slidably connected to the inner side of the upper mold, is L-shaped;

[0018] An electric slide rail is disposed on the upper surface of the support frame and is used to drive the control component to move.

[0019] The long groove is formed on the inner bottom of the electric slide rail.

[0020] Preferably, the control assembly includes a protective housing, and the polishing assembly is fixedly connected to the protective housing. The polishing assembly includes:

[0021] The second telescopic rod, the upper end of which is fixedly connected to the inside of the protective shell;

[0022] A drive device, which is fixedly connected to the lower end of the second telescopic rod;

[0023] A stabilizer bar is rotatably connected below the drive device, and annular grooves are provided on the inner sides of the upper and lower ends of the stabilizer bar.

[0024] A steel ball, which is rotatably connected to the lower end of the stabilizer bar.

[0025] Preferably, the stabilizer bar has an auxiliary component inside, the auxiliary component including:

[0026] A keyway is formed on the outer wall of the stabilizer bar, and is located on the lower side of the stabilizer bar and close to the steel ball;

[0027] The third telescopic rod is fixed inside the stabilizer rod;

[0028] The active rod is rotatably connected to the lower end of the third telescopic rod;

[0029] The driven rod, the upper end of which is rotatably connected to the lower end of the driving rod;

[0030] A coarse grinding wheel is rotatably connected at the rotatable connection between the driving rod and the driven rod.

[0031] Preferably, the outer surface of the stabilizer bar is fixed with a plurality of protrusions.

[0032] Preferably, an airbag is provided above the second telescopic rod;

[0033] A connecting pipe is fixedly connected to the outside of the drive device, and the upper end of the connecting pipe is connected to the airbag.

[0034] The upper end of the stabilizer bar has multiple liquid outlet holes, which are connected to the connecting pipe.

[0035] Preferably, a telescopic rod is fixedly connected inside the protective shell, and a drive rod is provided at the lower end of the telescopic rod.

[0036] A connecting spring is fixedly connected between the lower end of the first telescopic rod and the upper end of the drive rod.

[0039] Preferably, a torsion spring is provided at the rotatable connection between the cam and the protective shell.

[0040] The beneficial effects of this invention are as follows:

[0041] 1. In the silicone mold assembly of the present invention, when the distance sensor detects that the stabilizer is about to approach the silicone product, the electric slide rail reduces its driving speed under the control of the mold equipment system, thereby reducing the moving speed of the control component. This prevents the stabilizer from contacting the parting line of the silicone product at too high a speed, which could cause the sandpaper on the stabilizer to over-polish a certain area of ​​the silicone product if the electric slide rail brakes too late.

[0042] 2. The silicone mold assembly of the present invention allows for the selection of sandpaper with a suitable grit based on the hardness of the manufactured silicone product. The sandpaper is then rolled up and installed in an annular groove, enabling the rotating stabilizer to drive the sandpaper to rotate. The electric slide rail automatically operates after a period of intermittent movement, thereby driving the control component to move again. Simultaneously, the support frame slides along the edge of the upper mold, allowing the stabilizer to move to other positions on the silicone product's parting line for polishing. This solves the problem of the need for careful handling and time-consuming polishing when personnel use handheld special equipment. Attached Figure Description

[0054] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0055] Example 1:

[0056] The silicone mold assembly described in this invention, such as Figure 1-5 and Figure 7 ,include:

[0057] Lower mold 1;

[0058] Upper mold 11, which is symmetrically distributed vertically with the lower mold 1;

[0059] The mold cavity 12 is respectively disposed in the upper mold 11 and the lower mold 1; a lifting plate is slidably installed in the mold cavity 12 of the lower mold 1, the lifting plate is in close contact with the mold cavity 12 and can complete lifting and lowering.

[0060] Also includes:

[0061] Polishing unit 2 is disposed inside the upper mold 11 and is symmetrically distributed with the center line of the upper mold 11 as a reference line.

[0062] Control component 3, wherein the control component 3 is disposed inside the polishing unit 2;

[0063] Polishing component 4 is disposed inside the control component 3, and the control component 3 is used to drive the polishing component 4 to move;

[0064] The polishing component 4 is used to polish the rough edges of the parting line of the silicone product.

[0065] The polishing unit 2 includes:

[0066] Support frame 21, which is slidably connected to the inner side of the upper mold 11, and the support frame 21 is "L" shaped;

[0067] An electric slide rail 22 is disposed on the upper surface of the support frame 21, and the electric slide rail 22 is used to drive the control component 3 to move.

[0068] Long groove 221 is formed at the bottom inner side of the electric slide rail 22.

[0069] The specific workflow is as follows:

[0070] During operation, the lower mold 1 and upper mold 11 are first installed in the mold equipment. Sandpaper of appropriate grit is selected according to the hardness of the silicone and installed in the polishing component 4. Then, the operator operates the machine to close the mold and injects silicone liquid into the mold cavity 12, waiting for the silicone to cure in the mold cavity 12. After the silicone has cured in the mold cavity 12, the operator operates the equipment to separate the lower mold 1 and upper mold 11 and controls the lifting plate in the mold cavity 12 of the lower mold 1 to rise and push out the silicone product. Then, the polishing unit 2 is powered on and runs, thereby controlling the component 3 to slide in the electric slide rail 22 to adapt to the lateral dimensions of the silicone product. At the same time, the component 3 drives the internal polishing component 4 to run, so that the polishing component 4 grinds and polishes the parting line on the silicone product, removing the burrs on the parting line, thus eliminating the need for manual grinding and polishing.

[0071] like Figure 4-5As shown, the control component 3 includes a protective shell 31, and the polishing component 4 is fixedly connected to the protective shell 31. The polishing component 4 includes:

[0072] The second telescopic rod 41, the upper end of which is fixedly connected to the inside of the protective shell 31;

[0073] Drive device 411, which is fixedly connected to the lower end of the second telescopic rod 41;

[0074] A stabilizer bar 42 is rotatably connected below the drive device 411, and annular grooves are provided on the inner sides of the upper and lower ends of the stabilizer bar 42.

[0075] Steel ball 43 is rotatably connected to the lower end of the stabilizer bar 42.

[0076] Furthermore, after the polishing assembly 4 is powered on, the second telescopic rod 41 in the polishing assembly 4 will also be powered on and run, causing the second telescopic rod 41 to extend and push the drive device 411 and the stabilizing rod 42 to move down. Through the long groove 221 at the bottom of the electric slide rail 22, the bottom of the stabilizing rod 42 contacts the inner surface of the mold cavity 12. At the same time, the drive device 411 is fixed to the lower end of the second telescopic rod 41, and the drive device 411 is preferably a drive motor. When the drive motor is powered on, it can drive the stabilizing rod 42 to rotate. At the same time, annular grooves are opened on the inner sides of the upper and lower ends of the stabilizing rod 42, so that the personnel can select the appropriate grit sandpaper according to the hardness of the silicone product after it is made, and then roll up the sandpaper and embed it in the annular groove. This avoids the sandpaper grit being too large or too small affecting the polishing effect of the rough edges of the silicone product. Then the stabilizing rod 42 rotates and drives the sandpaper to rotate, ensuring that each side of the sandpaper can participate in the polishing of the rough edges of the silicone product. This prevents the sandpaper from always polishing on one side, which can easily increase the wear degree of a certain side of the sandpaper and reduce the polishing effect.

[0077] During polishing, a predetermined program can be used to control the combined motion trajectory of the support frame 21, control component 3, and second telescopic rod 41 to be the same as the outer contour of the silicone product. At the same time, the stabilizer rod 42 is equipped with a pressure sensor and a distance sensor. When the distance sensor detects that the stabilizer rod 42 is about to approach the silicone product, the electric slide rail 22 reduces its driving speed under the control of the mold equipment system, which reduces the moving speed of the control component 3. This prevents the stabilizer rod 42 from contacting the parting line of the silicone product at too high a speed. If the electric slide rail 22 brakes too late, the sandpaper on the stabilizer rod 42 may cause over-polishing of a certain area on the silicone product.

[0078] As the electric slide rail 22 drives the control component 3 to move slowly, when the stabilizer bar 42 contacts the parting line of the silicone product, the pressure sensor in the stabilizer bar 42 detects a pressure change and controls the electric slide rail 22 to brake, so that the stabilizer bar 42 is stabilized at the edge of the parting line of the silicone product. Then, sandpaper is used to remove the burrs on the parting line of the silicone product.

[0079] Meanwhile, the upper mold 11 is equipped with a drive slide rail of the same type as the electric slide rail 22. The drive slide rail drives the support frame 21 to slide along the edge of the upper mold 11, allowing the stabilizer 42 to move to other positions on the parting line of the silicone product for polishing. A pressure sensor ensures that the stabilizer 42 does not over-contact the silicone product each time it comes into contact with it. Furthermore, the electric slide rail 22 drives the control component 3 to reciprocate, allowing the stabilizer 42 to adapt to the curves on the parting line of the silicone product. This solves the problem of the need for careful handling and time-consuming polishing when using handheld equipment. Additionally, the polishing units 2 are symmetrically distributed along the centerline of the upper mold 11. Therefore, a single stabilizer bar 42 only needs to polish one side of the parting line of the silicone product, which indirectly improves the polishing efficiency. This completely polishes the burrs on the parting line of the silicone product, improving both the aesthetics and performance of the silicone product. It solves the problem that existing equipment mainly relies on manual operation, which can easily lead to over-polishing and dimensional deviations in silicone products. At the same time, the equipment can be operated without requiring highly experienced personnel, reducing labor costs. It also allows for the removal of burrs on the parting line of the silicone product without removing the product, avoiding the need to transfer the silicone product back and forth to different workstations and improving production efficiency.

[0080] Meanwhile, a steel ball 43 is rotatably connected to the bottom of the stabilizer bar 42. When the bottom of the steel ball 43 contacts the inner surface of the mold cavity 12, the stabilizer bar 42 cannot continue to move. Then, as the stabilizer bar 42 moves along the bottom of the mold cavity 12, the steel ball 43 can reduce the resistance during the movement of the stabilizer bar 42 and will not cause significant wear to the inside of the mold cavity 12.

[0081] Example 2:

[0082] The silicone mold assembly described in this invention, such as Figure 8-9 As shown, the difference between Embodiment 2 and Embodiment 1 is that an auxiliary component 5 is provided inside the stabilizer bar 42, and the auxiliary component 5 includes:

[0083] Keyway 51, the keyway 51 is formed on the outer wall of the stabilizer bar 42, and is located on the lower side of the stabilizer bar 42 and close to the steel ball 43;

[0084] The third telescopic rod 52 is fixedly connected inside the stabilizer rod 42;

[0085] Active rod 53, which is rotatably connected to the lower end of the third telescopic rod 52;

[0086] Driven rod 54, the upper end of which is rotatably connected to the lower end of driving rod 53;

[0087] A coarse grinding wheel 55 is rotatably connected at the rotatable connection between the driving rod 53 and the driven rod 54.

[0088] The specific workflow is as follows:

[0089] If the silicone product has a high hardness, in order to improve the polishing efficiency, manual polishing is usually done by first pre-treating the rough edges of the parting line with coarse sandpaper, and then polishing the parting line with finer sandpaper. This requires changing equipment back and forth, increasing the polishing time. In this case, polishing can be achieved by using an auxiliary component 5 in the stabilizer 42. During the polishing process, finer sandpaper is first installed in the annular grooves at the upper and lower ends of the stabilizer 42. Then, a notch is cut on the lower side of the fine sandpaper at the position corresponding to the keyway 51. When the stabilizer 42 is polishing, the third telescopic rod 52 is powered on and drives the active rod 53 to rotate. The active rod 53 drives the driven rod 54 to rotate, causing the coarse grinding wheel 55 at the connection between the active rod 53 and the driven rod 54 to move outward through the keyway 51. Then, when the stabilizer 42 rotates, it drives the coarse grinding wheel 55 to rotate to pre-treat the parting line of the silicone product.

[0090] After the parting line of the silicone product is pre-treated once, the No. 3 telescopic rod 52 is reset, which drives the active rod 53 and the driven rod 54 to reset, so that the coarse grinding wheel 55 is retracted from the keyway 51. Then the stabilizing rod 42 continues to rotate, so that the fine sandpaper on the outside can further polish the parting line of the silicone product. This solves the trouble of manually changing equipment and reduces the time required for polishing.

[0091] Example 3:

[0092] The silicone mold assembly described in this invention, such as Figure 7 As shown, a plurality of protrusions 421 are fixedly connected to the outer surface of the stabilizer bar 42.

[0093] The specific workflow is as follows:

[0094] The outer side of the stabilizer bar 42 is provided with a protrusion 421. When the stabilizer bar 42 rotates to polish the parting line of the silicone product, the protrusion 421 increases the friction between the sandpaper and the stabilizer bar 42. Thus, the protrusion 421 can prevent the sandpaper from slipping during the polishing process and ensure that the sandpaper is in a more stable state during the sanding process.

[0095] Example 4:

[0096] The silicone mold assembly described in this invention, such as Figure 4-5 As shown, a telescopic rod 311 is fixedly connected inside the protective shell 31, and a drive rod 312 is provided at the lower end of the telescopic rod 311.

[0097] A connecting spring 313 is fixedly connected between the lower end of the first telescopic rod 311 and the upper end of the drive rod 312.

[0098] The specific workflow is as follows:

[0099] When the polishing assembly 4 is running, the first telescopic rod 311 in the protective shell 31 will also be energized and run. As a result, the first telescopic rod 311 pushes the drive rod 312 down through the connecting spring 313, so that the lower end of the drive rod 312 contacts the silicone product and presses the silicone product into the mold cavity 12. Then the first telescopic rod 311 continues to run, so that it receives a reaction force and begins to compress the connecting spring 313. A pause switch for the first telescopic rod 311 is provided between the connecting spring 313 and the connection point of the first telescopic rod 311. When the connecting spring 313 is compressed, it will squeeze the pause switch at the connection point, so that the first telescopic rod 311 stops running, thereby fully pressing the silicone product and preventing the silicone product in the mold cavity 12 from moving during the polishing process.

[0100] When the polishing position of the silicone product is changed, the first telescopic rod 311 retracts and resets, thereby releasing the pressure on the silicone product. Then, after the control component 3 and the polishing component 4 move to the next position, the first telescopic rod 311 runs again and drives the drive rod 312 to press the silicone product, ensuring that the silicone product is pressed tightly every time it is polished, preventing the silicone product from moving during polishing and affecting the polishing effect.

[0101] Example 5:

[0102] The silicone mold assembly described in this invention, such as Figure 5-6 As shown, an airbag 44 is provided above the second telescopic rod 41;

[0103] A connecting pipe 412 is fixedly connected to the outside of the driving device 411, and the upper end of the connecting pipe 412 is connected to the airbag 44.

[0104] The upper end of the stabilizer bar 42 is provided with a plurality of liquid outlet holes 422, and the liquid outlet holes 422 are connected to the connecting pipe 412;

[0105] A cam 441 is provided below the airbag 44, and the cam 441 is rotatably connected to the inner wall of the protective shell 31.

[0106] A connecting rope 442 is fixedly connected to the inner side of the cam 441, and the other end of the connecting rope 442 is fixedly connected to the outer surface of the drive rod 312.

[0107] A torsion spring is provided at the rotatable connection between the cam 441 and the protective shell 31.

[0108] The specific workflow is as follows:

[0109] The airbag 44 is filled with liquid polishing agent. When the drive rod 312 moves to the bottom under the push of the first telescopic rod 311, the drive rod 312 will drive the connecting rope 442 to move. The connecting rope 442 will drive the cam 441 to rotate, so that the cam 441 will squeeze the bottom of the airbag 44. As a result, the airbag 44 will be under pressure, causing the liquid polishing agent inside to flow into the connecting tube 412. Then, the liquid polishing agent in the connecting tube 412 will flow further into the liquid outlet 422 under the action of gravity, and then flow onto the sandpaper. As a result, during the polishing process, the parting line of the silicone product is smoother and more regular after polishing due to the participation of the liquid polishing agent, which enhances the removal effect of burrs.

[0110] When the first telescopic rod 311 retracts and resets, it drives the rod 312 to reset, thereby loosening the connecting rope 442. This causes the cam 441 to lose the tension constraint of the connecting rope 442 and then reset under the action of the inner torsion spring. As a result, the airbag 44 loses the pressure of the cam 441, and the liquid polishing agent inside flows back to the bottom of the airbag 44 under the action of gravity, waiting for the cam 441 to rotate again to squeeze it. At the same time, personnel regularly inject an appropriate amount of polishing agent into the airbag 44 to ensure that the airbag 44 does not lack polishing agent.
