Description

Technical Field

[0001] The invention relates to the technical field of oil pressure molding dies, in particular to an oil pressure molding dies for silicone products which are easy to position. Background Art

[0002] Silica gel is a transparent or milky white granular solid with an open porous structure and strong adsorption capacity. It can adsorb a variety of substances. When dilute sulfuric acid (or hydrochloric acid) is added to an aqueous solution of water glass and allowed to stand, it becomes a hydrous silica gel and solidifies. The electrolyte Na+ and SO4 2-(Cl-) ions dissolved in it can be removed by washing with water, and silica gel can be obtained after drying.

[0003] The hydraulic molding mold for silicone products is generally composed of an upper and lower mold. When producing silicone products, silicone is often injected into the mold, and then a hydraulic press is used to push the upper or lower mold to press the silicone into shape. Hydraulic pressure refers to a technology that uses a hydraulic system to transmit a working medium (such as liquid) to an actuator through pressure to achieve mechanical action. Hydraulic pressure can convert mechanical energy into hydraulic energy, and use liquid to transmit force and execution power.

[0004] When manufacturing silicone products, it is necessary to melt the silicone raw materials and mix them. During this process, impurities are easily attached, and there may be some silicone particles that are not completely melted. Oil pressure on silicone containing impurities and particles will cause the surface of silicone products to be rough and uneven, and the quality of the finished products will decrease. The melted silicone needs to be injected into the mold through the injection hole. After the device is discontinued, the residual silicone inside the injection hole will solidify and agglomerate, causing the injection hole to be blocked. The injection hole needs to be penetrated during subsequent injection molding, which is more complicated. At the same time, during oil pressure, due to the presence of the injection hole, a small bulge will be left at the position corresponding to the injection hole after the silicone oil pressure molding, affecting the appearance of the product.

[0016] Compared with the prior art, the oil pressure molding mold for silicone products that is easy to position has the following beneficial effects: 1. The present invention firstly inputs the melted silicone into the outer cylinder through the top plate via the feeding pipe, and closes the electric valve, and then drives the half gear to rotate through the second motor, thereby driving the rack to move. When the half gear reaches the gearless position, the rack loses its limit, and under the action of the rebound force of the second spring, the inner cylinder is driven to move quickly inside the outer cylinder, and the electric valve is in a closed state, thereby squeezing the liquid silicone in the outer cylinder, and the pressure of the silicone increases, and the impurities in the silicone are filtered out through the X-shaped rubber plug and the inner cylinder, and the silicone is made smoother, thereby improving the quality of silicone utensils after subsequent molding.

[0017] 2. The present invention works repeatedly and cooperates with the closing of the electric valve. Silicone will be continuously input from the X-shaped rubber plug into the inside, then into the injection tube, and then into the lower mold body through the injection tube. While inputting silicone, the concentrated brine in the inner cylinder is heated by the heating ring to keep it warm to prevent the silicone from solidifying. At the same time, the connecting hole and the insulation water tank are also filled with concentrated brine to keep the silicone in the injection tube from solidifying.

[0018] 3. The present invention inputs a suitable amount of silicone into the lower mold body, pushes it upward through the hydraulic cylinder, and closes the upper mold body and the lower mold body to complete the oil pressure molding of the silicone. During the oil pressure process, because the input of silicone is stopped, the first spring is not subjected to force, rebounds, and the plug is embedded in the circular groove of the upper mold body, so that the outlet of the injection tube can be blocked, thereby avoiding the problem of convex points at the injection hole position during oil pressure molding, which affects the aesthetics of the product.

[0019] Fourth, in the present invention, during the upward movement of the threaded rod, the first gear and the second gear will also move upward under the limitation of the limiting plate, and the telescopic rod will retract. When the threaded rod rotates and moves upward, it will drive the threaded rod to rotate and move upward. Under the action of the threaded rod rotating and moving upward, the T-shaped demoulding head and the lower mold body are more easily separated, avoiding the problem of silicone being stuck in the gap between the lower mold body and the T-shaped demoulding head, and the T-shaped demoulding head is difficult to separate from the lower mold body, resulting in demoulding failure.

[0020] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

The driving unit 300 includes a second motor 301, which is fixedly installed at the bottom of the top plate 102. A half gear 302 is fixedly installed at the output end of the second motor 301. The half gear 302 is a gear with half teeth. A rack 303 is fixedly installed at the bottom of the top plate 102. One side of the rack 303 is meshed with the half gear 302. An outer cylinder 305 is fixedly installed at the bottom of the top plate 102. A filter assembly 306 is slidably arranged inside the outer cylinder 305. A second spring 304 is sleeved on the outer wall of the outer cylinder 305, and the second spring 304 provides a rebound force.

[0025] like Figure 1 , Figure 3 , Figure 5 As shown, the anti-blocking component 106 includes an upper mold body 106-1, the outer wall of the upper mold body 106-1 is fixedly installed with the rack 303, a heating ring 106-2 is fixedly installed on the top of the upper mold body 106-1, a connecting hole 106-3 is opened inside the upper mold body 106-1, a heat-insulating water tank 106-4 is opened inside the upper mold body 106-1, the connecting hole 106-3 and the heat-insulating water tank 106-4 are connected to each other, a heating wire 106-5 is fixedly installed inside the upper mold body 106-1, the heating wire 106-5 is located in the heat-insulating water tank 106-4, an injection tube 107 is fixedly installed inside the upper mold body 106-1, and a first elastic tube 106-6 is fixedly installed on the top of the upper mold body 106-1.

[0026] Specifically, by repeatedly working the second motor 301 and closing the electric valve 104, the silicone will be continuously input from the X-shaped rubber plug 306-2 into the first elastic tube 106-6, and then into the injection tube 107, and enter the lower mold body 203 through the injection tube 107. While inputting the silicone, the concentrated brine in the inner cylinder 306-1 is heated by the heating ring 106-2 to keep it warm to prevent the silicone from solidifying. At the same time, the connecting hole 106-3 and the insulation water tank 106-4 are also filled with concentrated brine to keep the silicone in the injection tube 107 from solidifying.

[0027] like Figure 2 and Figure 8 As shown, the check assembly 108 includes a connecting plate 108-2, which is fixedly installed inside the injection tube 107, a second elastic tube 108-3 is fixedly installed at the bottom of the connecting plate 108-2, a first spring 108-4 is fixedly installed at the bottom of the connecting plate 108-2, the first spring 108-4 is located inside the second elastic tube 108-3, a plug 108-1 is fixedly installed at the bottom of the second elastic tube 108-3, the first spring 108-4 is fixedly installed on the top of the plug 108-1, a circular groove is opened at the bottom of the upper mold body 106-1, and the plug 108-1 is slidably plug-connected with the upper mold body 106-1 through the circular groove.

[0028] Specifically, after a suitable amount of silicone is input into the lower mold body 203, the hydraulic cylinder 201 is used to push upward, and the upper mold body 106-1 and the lower mold body 203 are closed to complete the oil pressure molding of the silicone. During the oil pressure process, the input of silicone is stopped, and the first spring 108-4 is not subjected to force. The first spring 108-4 rebounds and the plug 108-1 is embedded in the circular groove of the upper mold body 106-1, so that the outlet of the injection tube 107 can be blocked, thereby avoiding the problem of convex points at the injection hole position during oil pressure molding, which affects the aesthetics of the product.

[0029] like Figure 1 , Figure 3 , Figure 4 , Figure 6 As shown, the demoulding assembly 202 includes a T-shaped demoulding head 202-1, a threaded rod 202-2 is rotatably installed at the bottom of the T-shaped demoulding head 202-1, a threaded sleeve 202-3 is threadedly installed on the outer wall of the threaded rod 202-2, a semi-circular ring 202-4 is fixedly installed on the outer wall of the threaded sleeve 202-3, a cylinder 202-5 is fixedly installed on the top of the semi-circular ring 202-4, a shell 202-6 is fixedly installed at the bottom of the lower mold body 203, a T-shaped through groove is opened inside the lower mold body 203, the T-shaped demoulding head 202-1 is slidably plugged into the lower mold body 203 through the T-shaped through groove, and the cylinder 202-5 is fixedly installed at the bottom of the lower mold body 203.

[0030] The transmission assembly 204 includes a first gear 204-1, which is fixedly installed at the bottom of the threaded rod 202-2. The outer wall of the first gear 204-1 is meshed with the second gear 204-2. Limiting plates 204-3 are fixedly installed at both ends of the second gear 204-2. A telescopic rod 204-4 is fixedly installed on the top of the limiting plate 204-3. The output end of the first motor 204-5 is fixedly installed on the top of the telescopic rod 204-4. The limiting plate 204-3 and the first gear 204-1 are installed in a close fit. The first motor 204-5 is fixedly installed at the bottom of the lower mold body 203.

[0031] Specifically, in the process of the threaded rod 202-2 moving upward, the first gear 204-1 and the second gear 204-2 will also move upward under the limitation of the limiting plate 204-3, and the telescopic rod 204-4 will retract. When the threaded rod 202-2 rotates and moves upward, it will drive the threaded rod 202-2 to rotate and move upward. Under the action of the threaded rod 202-2 rotating and moving upward, the T-shaped demolding head 202-1 and the lower mold body 203 are more easily separated, avoiding the silicone being stuck in the gap between the lower mold body 203 and the T-shaped demolding head 202-1, and the T-shaped demolding head 202-1 is difficult to separate from the lower mold body 203, resulting in the problem of demolding failure.

[0032] like Figure 3 , Figure 5 As shown, the filter assembly 306 includes an inner cylinder 306-1, which is filled with concentrated brine. The inner cylinder 306-1 is slidably installed on the inner wall of the outer cylinder 305. A through hole is opened inside the inner cylinder 306-1. An X-shaped rubber plug 306-2 and a filter screen 306-3 are fixedly installed in the through hole of the inner cylinder 306-1. The filter screen 306-3 is located below the X-shaped rubber plug 306-2. The first elastic tube 106-6 is fixedly installed at the bottom of the inner cylinder 306-1 and is located outside the through hole. The inner cylinder 306-1 is fixedly installed on the top of the upper mold body 106-1.

[0033] Specifically, the melted silicone is fed into the outer cylinder 305 through the top plate 102 via the feed pipe 103, and the electric valve 104 is closed. Then, the half gear 302 is driven to rotate by the second motor 301, thereby driving the rack 303 to move. When the half gear 302 reaches the gearless position, the rack 303 loses its limit, and under the action of the rebound force of the second spring 304, the inner cylinder 306-1 is driven to move rapidly inside the outer cylinder 305, and the electric valve 104 is in a closed state, thereby squeezing the liquid silicone in the outer cylinder 305. The pressure of the silicone increases, and the impurities in the silicone are filtered out through the X-shaped rubber plug 306-2 and the inner cylinder 306-1, making the silicone smoother and improving the quality of silicone utensils after subsequent molding.

[0034] Working principle: First, the melted silicone is fed into the outer cylinder 305 through the feed pipe 103 through the top plate 102, and the electric valve 104 is closed. Then, the second motor 301 drives the half gear 302 to rotate, thereby driving the rack 303 to move. When the half gear 302 reaches the gearless position, the rack 303 loses its limit, and under the action of the rebound force of the second spring 304, the inner cylinder 306-1 is driven to move quickly inside the outer cylinder 305, and the electric valve 104 is in a closed state, thereby squeezing the liquid silicone in the outer cylinder 305. The pressure of the silicone increases, and the impurities in the silicone are filtered out through the X-shaped rubber plug 306-2 and the inner cylinder 306-1, making the silicone smoother and improving the quality of silicone utensils after subsequent molding. Secondly, by the second motor 301 repeatedly working and the electric valve 104 being closed, the silica gel will be continuously inputted from the X-shaped rubber plug 306-2 into the first elastic tube 106-6, and then into the injection tube 107, and then into the lower mold body 203 through the injection tube 107. While the silica gel is inputted, the concentrated brine in the inner cylinder 306-1 is heated by the heating ring 106-2 to keep it warm to prevent the silica gel from solidifying. At the same time, the connecting hole 106-3 and the heat preservation water tank 106-4 are also filled with concentrated brine to keep the silica gel in the injection tube 107 from solidifying. When the silicone is input from the injection tube 107 into the lower mold body 203, the plug 108-1 is stressed and stretches the first spring 108-4 and the second elastic tube 108-3, and the plug 108-1 is separated from the circular groove, so that the silicone can enter the lower mold body 203 from the injection tube 107; After a suitable amount of silicone is input into the lower mold body 203, the upper mold body 106-1 and the lower mold body 203 are closed by the hydraulic cylinder 201 to complete the hydraulic molding of the silicone. During the hydraulic molding process, the first spring 108-4 is not subjected to force because the input of silicone is stopped. The first spring 108-4 rebounds and the plug 108-1 is embedded in the circular groove of the upper mold body 106-1, so that the outlet of the injection tube 107 can be blocked, thereby avoiding the problem of convex points at the injection hole position during hydraulic molding, which affects the aesthetics of the product. After the oil pressure is completed, the hydraulic cylinder 201 drives the housing 202-6 to move downward, thereby driving the lower mold body 203 to move downward. An anti-stick coating is provided on the outer wall of the upper mold body 106-1. When the lower mold body 203 moves downward, the molded silicone will be separated from the upper mold body 106-1, and then the molded silicone needs to be demolded. When demolding, the telescopic rod 204-4 is driven to rotate by the first motor 204-5, thereby driving the limit plate 204-3 and the second gear 204-2 to rotate, thereby driving the first gear 204-1 to rotate, thereby driving the threaded rod 202-2 to rotate. Under the rotation and position limit of the semicircular ring 202-4, the threaded rod 202-2 rotates and moves upward; Finally, in the process of the threaded rod 202-2 moving upward, the first gear 204-1 and the second gear 204-2 will also move upward under the limitation of the limiting plate 204-3, and the telescopic rod 204-4 will retract. When the threaded rod 202-2 rotates and moves upward, it will drive the threaded rod 202-2 to rotate and move upward. Under the action of the threaded rod 202-2 rotating and moving upward, the T-shaped demolding head 202-1 and the lower mold body 203 are more easily separated, avoiding the silicone being stuck in the gap between the lower mold body 203 and the T-shaped demolding head 202-1, and the T-shaped demolding head 202-1 is difficult to separate from the lower mold body 203, resulting in demolding failure.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
