Abstract
The utility model provides a hydraulic motor chain transmission gear thread-dropping mechanism which ensures that dropping of internal thread products is convenient, and efficiency is high. The hydraulic motor chain transmission gear thread-dropping mechanism comprises an A plate, a push plate, a support plate, a front mould core and a back mould core. A cavity is arranged between the front mould core and the back mould core. The hydraulic motor chain transmission gear thread-dropping mechanism is characterized in that the back mould core is specifically a back thread mould core with an outer thread on a ring surface on the upper portion of the back mould core. A circular truncated cone structure which expands port downwards is below the outer thread of the back thread mould core. An insert structure matched with the circular truncated cone structure is sleeved outside the circular truncated cone structure. The bottom face of the mould insert structure is supported by the support plate and arranged inside an installing groove of the push plate. The lower end of the back thread mould core is specifically a gear structure.
Description
Technical field
The utility model relates to the technical field of injection mould mould structure, is specially a kind of hydraulic motor chain drive gear and takes off thread mechanism.
Background technology
Some is as the bottle cap series products, usually has internal thread in the lid the inside, and internal thread is back-off in the depanning direction of mould, and the existence of back-off is arranged, and goods just can not take out smoothly, at this moment will use and take off spiral shell mechanism.Material as fruit product softer (as mineral water bottle cap, material mostly is HDPE) in the not dark situation of screw thread, can adopt the mode of forced stripper mechanism.But some goods, material is harder, and screw thread is deep time marquis again, can damaged screw during forced stripper mechanism.
Summary of the invention
For the problems referred to above, the utility model provides a kind of hydraulic motor chain drive gear to take off thread mechanism, and it makes the internal thread product conveniently come off, and efficient is high.
a kind of hydraulic motor chain drive gear takes off thread mechanism, its technical scheme is such: it comprises the A plate, push pedal, supporting plate, front cavity, rear cavity, described front cavity, it is die cavity between rear cavity, it is characterized in that: described rear cavity is specially top loop and has worn externally threaded rear thread die, the externally threaded below of described rear thread die is the frustum cone structure of downward enlarging, the outer cover of described frustum cone structure is equipped with the insert structure that is mated, the bottom surface of described insert structure is supported on described supporting plate, described insert structure is positioned at the mounting groove of described push pedal, the lower end of described rear thread die is specially gear structure, the described gear structure gear input gear that is connected with a joggle, described input gear is set in the output of main shaft, the two ends of described main shaft are supported on described supporting plate by bearing respectively, in the installation cavity of base plate, the input adapter sleeve of described main shaft is equipped with input sprocket, described input sprocket connects outside output chain gear by chain, motor base is fastenedly connected the outer face of described supporting plate, hydraulic motor is supported on described motor base, the bottom output of described hydraulic motor is set with described output chain gear, described square iron chord position is in described supporting plate, between base plate, described input gear, gear structure, input sprocket, chain all is positioned at the cavity of described square iron frame inside, inner mold insert is mounted on described die cavity after running through the center of described rear thread die, the bottom outer ring surface of described rear thread die is the external screw thread anchor ring, described external screw thread anchor ring is set in thread bush, the bottom supporting of described thread bush is in the mounting groove of described base plate, leave the gap between the end face of the bottom end face of described rear thread die and the mounting groove of described base plate.
after adopting said structure of the present utility model, goods are after injection moulding is completed, the front and back mould is opened, the threaded portion of goods is enclosed within on the rear thread die of mould, at this moment hydraulic motor drives the output chain gear rotation, rotated by the chain-driving main shaft again, input gear on main shaft drives the rear thread die again and rotates, because rear mold thread core bottom outer ring surface is the external screw thread anchor ring, this section is threaded in thread bush, so the rear mold thread core moves in thread bush when rotating, until the thread segment on the rear thread die and product break away from, by push pedal, product is ejected again, and then resetted by hydraulic motor drive rear thread die, complete and reset until frustum cone structure is close to the inner surface of the insert structure that is mated, carry out next injection cycle, it makes the internal thread product conveniently come off, and efficient is high.
