[0001] The utility model relates to the technical field of molding machines, in particular to a silicone oil hydraulic molding machine. Background Art

[0002] Silicone is a high molecular compound connected by silicon-oxygen bonds and is usually used as an elastic material or a sealing material. Nowadays, when making silicone parts, it needs to be operated on a silicone oil hydraulic molding machine. The silicone oil hydraulic molding machine is a device specially used for the production of silicone products. It forms and processes the silicone material through a hydraulic system and cooperates with a specific mold to complete the production of silicone parts.

[0003] However, when the existing silicone oil hydraulic molding machine extrudes the silicone material, it is not convenient to clean the burrs of the formed product, so that the staff needs to clean it manually, increasing the manual labor. In view of this, we propose a silicone oil hydraulic molding machine. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following further describes the technical solutions of the present utility model with reference to the accompanying drawings and specific embodiments.

[0019] Embodiment

[0020] As Figures 1-3As shown in the figure, a silicone oil hydraulic molding machine proposed by the present utility model includes a workbench 1. A lower mold base 2 is installed on the top wall of the workbench 1. The bottom ends of a plurality of vertical rods 3 are fixedly connected to the top wall of the workbench 1. The bottom of a top plate 4 is connected to the top ends of the plurality of vertical rods 3, and the vertical rods 3 play a supporting role for the top plate 4. A hydraulic cylinder 5 is fixedly installed on the top wall of the top plate 4. The output end of the hydraulic cylinder 5 penetrates through a through hole opened in the top plate 4 and is fixedly connected to the top wall of an upper mold base 6, which facilitates driving the upper mold base 6 to move. In the descending state, the upper mold base 6 can cooperate with the lower mold base 2 to extrude and form the silicone placed on the lower mold base 2. A sliding hole is opened in the upper mold base 6, and the plurality of vertical rods 3 are respectively arranged in the corresponding sliding holes, thereby playing a guiding and limiting role for the moving upper mold base 6 to prevent the upper mold base 6 from tilting during the subsequent stamping of the silicone, which affects the production of silicone parts. A second cutter 8 is fixedly installed on the bottom wall of the upper mold base 6. A moving groove is opened in the bottom wall of the upper mold base 6. A first spring is installed in the moving groove. The top end of the first spring is connected to the wall of the moving groove, and the bottom end of the first spring is connected to the top of the second cutter 8, so that when the upper mold base 6 drives the second cutter 8 to descend, the burrs on the silicone part can be cut off, which is beneficial to subsequent cleaning. The moving groove and the first spring are not shown in the figure.

[0021] Furthermore, a cutting assembly 7 and a second cutter 8 for facilitating the cutting of the burrs of the silicone part are installed at the bottom of the upper mold base 6. The cutting assembly 7 is arranged in a movable cavity opened in the bottom wall of the upper mold base 6. The cutting assembly 7 includes a second spring 71. A plurality of second springs 71 are all arranged in the movable cavity. Their top ends are fixedly connected to the wall of the movable cavity, and the bottom ends are fixedly connected to the top wall of a U-shaped plate 72, which facilitates driving the U-shaped plate 72 to move. A first cutter 73 is fixedly installed on the bottom wall of the U-shaped plate 72 and is arranged in a U-shaped state. By driving it to press down by the upper mold base 6, the first cutter 73 can cut off the burrs around the silicone part, providing convenience for subsequent cleaning work. And with the setting of the second spring 71, the first cutter 73 can be received in the movable cavity to avoid affecting the stamping production of the silicone part. At the same time, under the action of automatic edge cutting, there is no need for workers to manually clean the burrs, saving labor.

[0022] Further, an inclined cavity is formed on the wall body facing the workbench 1, and a blanking assembly 9 for facilitating the cleaning of burrs is arranged on the lower die base 2. The blanking assembly 9 includes air cylinders 91. A plurality of air cylinders 91 are all installed in the first blanking openings formed on the bottom wall of the inclined groove. The second blanking openings formed on the lower die base 2 correspond to the positions of the first blanking openings. A movable seat 92 is arranged in the second blanking openings, and the bottom wall thereof is connected to the output ends of the plurality of air cylinders 91, facilitating the driving of the movable seat 92 to descend by the air cylinders 91, so that the burr materials move into the inclined groove when the movable seat 92 descends, and are discharged from the workbench 1 through the inclined groove, and are collected centrally by a conventional container, facilitating subsequent reuse to prevent resource waste; An air extraction pump 93 is fixedly installed in the cavity formed in the movable seat 92. The outlet end of the air extraction pump 93 is exposed at the bottom of the movable seat 92. The suction end of the air extraction pump 93 is communicated with the positioning cavity formed on the movable seat 92. Since a plurality of suction holes are formed on the top wall of the positioning cavity, when the air extraction pump 93 extracts air from the positioning cavity, the bottom of the burr materials is positioned through the positioning holes, avoiding subsequent detachment from the movable seat 92 during the cleaning process, resulting in accumulation on the lower die base 2 and affecting the subsequent work.

[0023] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
