摘要： A push-type die closing unit for injection molding machines in which a stationary die carrier plate, a rearwardly spaced head plate, and four tie rods form a rigid guide structure for a movable die carrier frame to which the piston rod of a linear actuator with power cylinder and auxiliary cylinder is centrally connected, for the direct and cant-free transmission of elevated closing pressures to the die carrier frame and die. The die carrier frame has axially spaced walls joined by four guide sockets and by pressure transfer ribs, a central accessory space defined therebetween accommodating, in conjunction with a hollow forward portion of the piston rod, an ejection device or other accessory device and a hydraulic drive therefor.

摘要： This invention embodies an intensifier cylinder assembly within the main hydraulic ram of a plastic molding machine whereby the clamping force holding the mold halves together can be increased during the shot cycle of the machine by at least three times the normal clamp force of the machine. Additionally, the location of the intensifier reduces the number of high pressure hydraulic fittings in the machine improving the safety factor while reducing the overall cost of the intensifier itself since the ram piston now becomes the housing for the intensifier piston.
摘要翻译：本发明体现了塑料成型机的主液压柱塞内的增压筒组件，由此在机器的喷射循环期间，将半模保持在一起的夹紧力可以增加机器的正常夹紧力的至少三倍。此外，增压器的位置减少了机器中的高压液压配件的数量，从而提高了安全系数，同时降低了增压器本身的总体成本，因为活塞活塞现在变成用于增压活塞的壳体。

摘要： A mold clamping mechanism for an injection molding machine characterized in that a relatively large mold clamping cylinder has a passage in its piston intercommunicating the head and rod ends of said mold clamping cylinder during stroking of said piston by a relatively small actuating cylinder for flow of oil from said head end into said rod end and into a makeup fluid tank having a capacity corresponding to the displacement of the piston rod of said mold clamping piston and vice versa during the respective mold opening and closing strokes. To effect mold clamping at required tonnage, the mold clamping cylinder has a port through which fluid under high pressure is admitted not only into the mold clamping piston to act on a fluid pressure actuated valve therein to close said passage, but also into the head end of the mold clamping cylinder to pressurize the fluid trapped therein by the closing of said passage.The mold clamping mechanism herein is further characterized in that an indexable mold supporting platen carries a plurality of mold sections for successive indexing to register with a mold section carried by a movable mold supporting platen and adapted to be clamped by said mold clamping mechanism against a stationary platen.

摘要： A hydraulic molding press comprising a main cylinder in which a main ram is mounted for forward and reverse movement and the main ram has a booster cylinder therein into which a hollow stationary booster ram extends. A control valve comprising a valve housing is provided at the end of the main cylinder and the booster ram extends therethrough. The valve housing includes a removable portion called a booster ram cap which threads onto and supports the end of the booster ram. The booster ram cap is detachably secured to the valve housing and the latter is detachably secured to the end of the main cylinder by four studs. A prefill tank connects to the valve housing for supplying prefill fluid to the main cylinder as the main ram is moved rapidly forward by booster fluid supplied through the booster ram from a port in the booster cap. A prefill valve piston slideably mounted in the valve housing is movable to close off prefill fluid flow from the prefill tank. The piston has a central opening through which the booster ram extends. The opening in the piston also serves as a fluid passage for supplying high pressure fluid to the main ram after the piston is moved forward to closed position. Fluid to this passage is supplied through a pair of prefill chambers in the booster ram cap which opens when the prefill pins are moved forward by pilot pressure to close the prefill valve piston. The prefill valve piston is controlled by a two-position remotely operated valve. The prefill pins are continually under pilot pressure. Forward and reverse movement of the main ram is controlled by a three-position remotely operated valve. To effect reverse movement of main ram, the two-position valve operates to decompress the high pressure fluid behind the main ram and opens the prefill valve piston to allow free fluid flow to the prefill tank. Then the three-position valve operates to move the main piston in reverse.
