Problems solved by technology
[0002] At present, the plastic or rubber product production industry knows that the mold opening speed must be greater than 500mm on the large-tonnage special foam molding machine for plastic or rubber products such as shoe soles, foamed floor glue, insulation boards, luggage linings, diving clothing materials, etc. / s can ensure the qualified performance of the product, and the sticky material phenomenon of the product affects the mold opening speed to varying degrees. The traditional design always increases the mold opening valve to increase the mold opening speed to meet the product performance, thus unconsciously increasing the mold opening speed.

The invention discloses an auxiliary mold-opening mechanism which comprises an upper footstock and an oil cylinder seat, and also comprises a column, middle hot plates, and a middle hot plate positioning mechanism which are disposed between the upper footstock and the oil cylinder seat; a positioning support is mounted at the bottom surface of the middle hot plate positioning mechanism; a plurality of guide rods are connected between the positioning support and the upper footstock; through holes are disposed on the upper footstock and correspond to the guide rods; a counterbore is disposed on the middle hot plate; a elastic member is disposed in the counterbore; one end of the guide rod passes through the through hole on the upper footstock and is fixed on the upper footstock; the middle hot plates are stringed on the guide rods one by one; and the other end of the guide rod passes through a mobile seat and is fixed on the positioning support. During the rising process of the mobile seat, the auxiliary mold-opening mechanism overcomes the force of a spring and allows a machine to close molds, perform pressurization and operate with a maintained pressure, and the spring generates pretightening force; the machine opens the molds, and transient mold opening is realized by the particularity of the machine performance; the spring releases the pretightening force instantly; and the functions of speed increase assistance and bonding resistance are generated.
Description
technical field [0001] The invention relates to the field of large-tonnage special foam molding machines for plastic or rubber products such as shoe soles, foamed floor glue, thermal insulation boards, luggage linings, diving clothing materials, etc., especially relates to an anti-sticking material and an auxiliary mold opening mechanism that helps speed up . Background technique [0002] At present, the plastic or rubber product production industry knows that the mold opening speed must be greater than 500mm on the large-tonnage special foam molding machine for plastic or rubber products such as shoe soles, foamed floor glue, insulation boards, luggage linings, diving clothing materials, etc. / s can ensure the qualified performance of the product, and the sticky material phenomenon of the product affects the mold opening speed to varying degrees.
