Description
Technical Field
The utility model relates to a dull and stereotyped rubber mold technical field that directly presses especially relates to a manual quick mold opening device of pressure injection mould.
Background
When the existing flat plate direct-pressing rubber mold is matched with forming equipment, some molds can be directly fixed on the equipment, and some molds are limited by equipment functions due to complex structure and more layers of templates, so that only manual mold opening is performed, the efficiency is low, the production cost is increased, and the molds are easy to damage.
For products with small size and high size precision, rubber materials are placed between a pressure plate and an upper template, the plasticized and flowable rubber materials are injected into a product cavity through a pouring gate by equipment pressure, after vulcanization molding, the templates are in a vacuum state due to the fact that rubber is fully filled and sealed, and positioning columns and guide columns with small gaps are arranged among the templates at all layers, the pressure plate and the upper template are difficult to open manually, therefore, workers can pry the pressure plate and the upper template by using other tools such as a screwdriver or a copper bar through external force, the cavity is extremely easy to damage in the operation process, and the efficiency is extremely low.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, provide a manual quick mold opening device of pressure injection mould, realize artifical quick die sinking, improve production efficiency, reduce with the damage of instrument sled open mould to the mould.
In order to solve the technical problem, the technical scheme of the utility model is that: the manual rapid die opening device for the injection die comprises a pressure plate, an upper die plate, a middle die plate and a lower die plate which are connected from top to bottom; a boss is arranged at the bottom of the pressure plate, a non-return white steel sheet is concavely arranged on the bottom surface of the boss, and a vacuum breaking air inlet hole is formed in the center of the pressure plate; the upper die plate is internally provided with a material pressing cavity matched with the boss of the material pressing plate, the bottom of the material pressing cavity of the upper die plate is provided with a plurality of glue injection ports, the glue injection ports are positioned above the die core, and the die core is arranged on the lower die plate.
Furthermore, the bottom surface of the boss is provided with a non-return white steel sheet through a flat head screw in a concave manner.
Furthermore, the vacuum breaking air inlet hole is a step-shaped through hole.
Furthermore, the bottom surface of the non-return white steel sheet is higher than or even with the bottom surface of the boss.
Furthermore, the single-side allowance between the boss and the material pressing cavity is 0.1 mm.
The utility model discloses a contrary white steel sheet isotructure ends destroys the vacuum between pressing material chamber and the material chamber through compressed air, realizes the die sinking of manual quick, laborsaving, not damaged.

Detailed Description
The following description of the present invention will be made with reference to the accompanying drawings 1-3.
The manual rapid die opening device for the injection die comprises a pressure plate 1, an upper die plate 5, a middle die plate 6 and a lower die plate 7 which are connected from top to bottom; a boss is arranged at the bottom of the pressure plate 1, a non-return white steel sheet 2 is concavely arranged on the bottom surface of the boss, and a vacuum breaking air inlet hole 3 is formed in the center of the pressure plate 1; set up in the cope match-plate pattern 5 with the boss assorted pressure material chamber of pressing flitch 1, a plurality of injecting glue mouth 8 has been seted up to cope match-plate pattern 5's pressure material chamber bottom, and injecting glue mouth 8 is located the top of mould core 9, and mould core 9 is installed on lower bolster 7.
The bottom surface of the boss is provided with a non-return white steel sheet 2 through a flat head screw 4 in a concave manner, and the size of the non-return white steel sheet 2 is 45 × 0.1 mm.
The vacuum breaking air inlet hole 3 is a step-shaped through hole,
the bottom surface of the non-return white steel sheet 2 is higher than or even with the bottom surface of the boss.
The single-side allowance between the boss and the material pressing cavity is 0.1 mm.
The rubber material is placed between the pressure plate 1 and the upper die plate 2, the plasticized and flowable rubber material is injected into a cavity of a product 10 through a pouring gate by equipment pressure, the non-return white steel sheet 2 is fixed on the pressure plate 1 by a flat head screw 4, the rubber material is injected into the cavity under pressure and transmits the pressure to the non-return white steel sheet 2, the non-return white steel sheet 2 is forced to upwards block the vacuum breaking air inlet 3, and the rubber material is prevented from overflowing. After vulcanization molding, because the abundant packing of rubber is airtight between pressure flitch 1 and the cope match-plate pattern 5, form vacuum state equally, the workman blows contrary white steel sheet 2 of contrary through broken vacuum inlet port 3 with the compressed air of 6-8 kilograms of power through the air gun, the air gets into between pressure flitch 1 and the cope match-plate pattern 5 through contrary white steel sheet 3 clearance all around, destroy the vacuum state of vulcanizing formation and jack-up pressure flitch 1, thereby easily open pressure flitch 1, then open cope match-plate pattern 5 in proper order, well template 6 and lower bolster 7, the effectual damage die cavity of avoiding in operation process, and efficiency obtains greatly improving.
Above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the design of the present invention, equivalent replacement or change should be covered within the protection scope of the present invention.
