Through adopting above-mentioned technical scheme, start through first hydro-cylinder and drive the rack and rotate, through the rotatory tooth that takes off of rack drive screw thread core, take off the tooth and accomplish the back, the second hydro-cylinder opens a department section of thick bamboo ejecting with the product through carving the mechanism drive slider to one side, takes the mode of twisting tooth slider earlier and then open to rotate the thread smoothly and deviate from, improves the thread quality by a wide margin, improves the yields, effectual saving enterprise manufacturing cost, improvement production efficiency.

The utility model discloses further set up to, the output of second hydro-cylinder is connected with wedge to one side, and the outside sliding connection of wedge inboard and slider to one side.

By adopting the technical scheme, the inclined wedge block and the sliding block are connected with the groove, so that the inclined wedge block can move the sliding block to open under the action of the second oil cylinder.

The utility model discloses further set up to, the bottom of template is provided with a department section of thick bamboo.

By adopting the technical scheme, when the sliding block is pulled open, the ejector sleeve is ejected out, so that the product is ejected out.

The utility model discloses further set up to, be provided with the cooperation pivoted draw-in groove that supplies rack and gear in the template.

Through adopting above-mentioned technical scheme, the setting up of draw-in groove prevents that rack and gear cooperation from causing the destruction to the inside other components of template when rotating.

The utility model discloses further set up to, the output of first hydro-cylinder is the setting of T shape, and the one end of rack is provided with rather than the complex recess.

By adopting the technical scheme, the first oil cylinder is convenient to separate when being maintained subsequently, and the whole die does not need to be disassembled.

To sum up, the utility model discloses mainly have following beneficial effect:

the utility model discloses a first hydro-cylinder starts to drive the rack and rotates, takes off the tooth through the rotation of rack drive screw thread core, takes off the tooth and accomplishes the back, and the second hydro-cylinder opens a department section of thick bamboo ejecting with the product through carving mechanism drive slider to one side, takes the mode of opening behind the hank tooth slider earlier to deviate from the smooth rotation of screw tooth, improves the screw tooth quality by a wide margin, improves the yields, effectual saving enterprise manufacturing cost, improvement production efficiency.
