Abstract
The invention provides a screw rod thread demoulding mechanism. The screw rod thread demoulding mechanism enables inner-thread products to be conveniently demould and is high in efficiency. The screw rod thread demoulding mechanism comprises an A plate, a pushing plate, a support plate, a front mould core and a back mould core, wherein a cavity is formed between the front mould core and the back mould core. The screw rod thread demoulding mechanism is characterized in that the back mould core is specifically a back thread mould core with outer threads on the upper-portion annular face, a circular truncated cone structure flaring downward is arranged under the outer threads of the back thread mould core, and an insert structure matched with the circular truncated cone structure is sleeved outside the circular truncated cone structure. The bottom face of the insert structure is supported on the support plate, the insert structure is located in an installing groove of the pushing plate, the lower end of the back thread mould core is specifically a gear structure, the gear structure is in meshed connection with an input gear, and the input gear is sleeved on a sleeve.
Description
Technical field
The present invention relates to the technical field of injection mould mould structure, be specially screw rod and take off thread mechanism.
Background technology
Some has internal thread in the lid the inside usually such as the bottle cap series products, 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 such as fruit product softer (such 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 invention provides screw rod and take off thread mechanism, it is so that the internal thread product conveniently comes off, and efficient is high.
Screw rod 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 the 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 sleeve, the two ends of described sleeve are supported on described supporting plate by bearing respectively, in the installation cavity of base plate, the center adapter sleeve of described sleeve is equipped with center-pole, the top evagination of described center-pole is in described A plate, the square iron chord position is in described supporting plate, between the base plate, described input gear, gear structure, sleeve 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 leaves the gap between the end face of the bottom end face of described rear thread die and the mounting groove of described base plate in the mounting groove of described base plate.
After adopting said structure of the present invention, goods are after injection moulding is finished, 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 center-pole rotates, input gear on the logical sleeve of band rotates, driving the rear thread die rotates again, because rear mold thread core bottom outer ring surface is the external screw thread anchor ring, this section is threaded in the 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 center-pole drive rear thread die, finish 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 is so that the internal thread product conveniently comes off, and efficient is high.
Description of drawings
