Description

Technical Field

[0001] This utility model relates to the field of silicone product processing technology, and in particular to an efficient demolding auxiliary device for silicone products. Background Technology

[0002] Silicone products are products made of silicone. Silicone, also known as silica gel, is a highly active adsorbent material and an amorphous substance. The main component of silicone is silicon dioxide, which is chemically stable and non-flammable. The processing of silicone products requires the application of molds, and injection molds are commonly used for molding.

[0003] A search revealed Chinese Patent Publication No. CN216267394U, which discloses a solid silicone injection mold, including a lower mold plate. A lower mold base is fixedly installed in the middle of the top surface of the lower mold plate, and a positioning guide post is inserted into the top of the lower mold base. An upper mold base is fixedly installed at the top of the positioning guide post, and an upper mold plate is fixedly installed at the top of the upper mold base. In use, this technical solution uses a motor to drive the upper mold plate and the upper mold to move upward and separate from the lower mold, thereby improving demolding efficiency. However, during use, the molded product is prone to sticking and retention at the parting surface, requiring manual cleaning or secondary ejection, which significantly affects processing efficiency during demolding and cannot meet usage requirements. Therefore, an efficient demolding auxiliary device for silicone products is proposed to solve the above-mentioned problems. Utility Model Content

[0029] A mold-opening mechanism 8 is fixedly installed at the bottom of the support frame 1, extending through to the top of the mounting platform 3 and fixedly connected to the top plate 6. The mold-opening mechanism 8 includes a servo motor 81, which is fixedly installed at the bottom of the support frame 1. A rotating cylinder 82, extending through to the top of the support frame 1, is rotatably installed at the bottom of the support frame 1. A bearing 821, rotatably connected to the support frame 1, is fixedly installed on the outer side of the rotating cylinder 82. Bevel gears 83 are fixedly installed on the output shaft of the servo motor 81 and the outer side of the rotating cylinder 82. The two bevel gears 83 mesh with each other. The internal threads of the rotating cylinder 82 are fitted with... The threaded rods 84 extend to the upper and lower sides. A lifting plate 85 is fixedly connected to the top of the threaded rods 84. A connecting rod 86 is fixedly installed on the top of the lifting plate 85 and is fixedly connected to the top plate 6. There are four connecting rods 86, which are distributed in a rectangular array.

[0030] A push-down assembly 9, penetrating into the upper mold 5, is fixedly installed on the top of the top plate 6. The push-down assembly 9 includes a support frame 91, which is fixedly installed on the top of the top plate 6. An electric push rod 92 is fixedly installed on the top of the support frame 91. The output end of the electric push rod 92 penetrates into the support frame 91 and is fixedly connected to a pressure plate 93. Several support springs 94 are fixedly installed between the bottom of the pressure plate 93 and the inner bottom wall of the support frame 91. A push-down rod 95, penetrating into the upper mold 5, is fixedly installed on the bottom of the pressure plate 93. A push-down plate 96, which is adapted to the upper mold 5, is fixedly connected to the bottom of the push-down rod 95.

[0031] The working process of this utility model:

[0032] Step 1: By controlling the servo motor 81 to start, the bevel gear 83 drives the rotating cylinder 82 to rotate, which in turn drives the threaded rod 84 to rise and fall vertically. This causes the lifting plate 85 to push the top plate 6 upward via the connecting rod 86, thus achieving rapid separation of the upper mold 5 and the lower mold 4.

[0033] Step 2: After the lifting plate 85 moves upward to a certain height, it pushes the connecting plate 74 of the pushing assembly 7 to move upward. The connecting plate 74 pushes the connecting block 72 and the ejector plate 71 upward through the ejector rod 73. The vibration motor 76 starts high-frequency micro-vibration simultaneously, and transmits elastic impact force through the auxiliary spring 77, so that the ejector plate 71 flexibly ejects the product.

[0034] Step 3: As the top plate 6 moves upward, the electric push rod 92 of the push assembly 9 drives the push rod 95 to press down. The push plate 96 pushes out the silicone product in the inner cavity of the upper mold 5 to avoid adhesion. The auxiliary product is removed from the cavity. The threaded rod 84 of the mold opening mechanism 8 rotates in the opposite direction to reset the top plate 6. The reset spring 75 and the auxiliary spring 77 automatically rebound, driving the ejector plate 71 to reset, thus completing the auxiliary demolding operation.

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