Abstract

The utility model discloses a double-layer retracting and demoulding mechanism for a movable mould, comprising a first push plate, a second push plate, an oblique guide post, a pull plate, a buckling machine, a limiting screw, a shutter and a plurality of retracting inserts, wherein the first push plate and the second push plate are arranged on the movable mould, and the pull plate is arranged on a fixed mould. When the movable mould and the fixed mould are separated from each other, the first parting is finished. The movable mould continues advancing and the pull plate drives the first push plate to move; driven by the pull plate, the first push plate gets rid of the controlling of the shutter; and the retracting inserts on the first push plate slide to leave spiral tooth positions so as to finish the second parting. The mould opening is continuously carried out and the first push plate is limited by the limiting screw; at the moment, the buckling machine is disconnected, the second push plate is flicked and then the oblique guide post drives the retracting inserts on the second push plate to slide to leave the spiral tooth positions so as to finish the third parting. The pull plate arranged on the fixed mould drives the two push plates of the movable mould to carry out dedentition layer by layer, which changes the traditional method of rotating dedentition of a round product, thereby achieving the purpose of convenient demoulding.

Description

The double-deck movable core,return core core puller mould emptier of a kind of dynamic model

Technical field

The utility model relates to a kind of mould emptier, refers in particular to the double-deck movable core,return core core puller mould emptier of a kind of dynamic model.

Background technology

In recent years, develop rapidly and general and engineering plastics improving constantly along with plastics industry at aspects such as intensity and precision, the range of application of plastic products is also in continuous expansion, as: household electrical appliance, instrument and meter, construction equipment, various fields such as auto industry, haberdashery and hardware, the shared ratio of plastic products just rapidly increases.A working of plastics reasonable in design often can replace a plurality of conventional metals parts.The trend of industrial products and daily product plastic constantly rises.Therefore the correct selection of mould has crucial effects to the quality of product.

The common inboard of circular product is a circle internal screw thread, and traditional method is to adopt the mode of rotation debentition that internal screw thread is deviate from, and the higher operation of cost is complicated, takes a lot of work, time-consuming.Therefore need a kind of conveniently stripped mechanism.

Summary of the invention

The purpose of this utility model is to provide a kind of dynamic model simple in structure, easy to use double-deck movable core,return core core puller mould emptier.

For realizing above-mentioned technical purpose; the technical solution adopted in the utility model is as follows: the double-deck movable core,return core core puller mould emptier of a kind of dynamic model; it comprises first push pedal; second push pedal; Angle Pin; arm-tie; deduction; limited screw; shutter and some movable core,return core core puller mold inserts; described first and second push pedal is arranged on the dynamic model; described arm-tie is arranged on the cover half; when deciding to finish when dynamic model separates somatotype for the first time; after this dynamic model continues to advance; arm-tie drives the first push pedal campaign; the control of shutter is thrown off in first push pedal under the drive of arm-tie; movable core,return core core puller mold insert in first push pedal slides and throws off the thread position; finish somatotype for the second time, continue the restriction that die sinking first push pedal is subjected to limited screw, this moment, deduction was thrown off; thereby second push pedal flicks Angle Pin and drives movable core,return core core puller mold insert in second push pedal and slide and throw off the thread position, finishes somatotype for the third time.

The double-deck movable core,return core core puller mould emptier of the utility model dynamic model compared with prior art; has following beneficial effect: by the two-layer push pedal debentition successively by different level that is located at the arm-tie drive dynamic model on the cover half; change the traditional approach of circular product rotation debentition, reached conveniently stripped purpose.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further.

Please refer to Fig. 1 to shown in Figure 5, the double-deck movable core,return core core puller mould emptier of a kind of dynamic model of the utility model, it comprises first push pedal 1, second push pedal 2, Angle Pin 3, arm-tie 4, deduction 5,

limited screw

6,7, shutter 8 and movable core,return core core puller mold insert S1, S2, S3, S4, S5 and S6, described first and

second push pedal

1,2 are arranged on the dynamic model, described arm-tie 4 is arranged on the cover half, when deciding to finish when dynamic model separates somatotype for the first time, after this dynamic model continues to advance, arm-tie 4 drives first push pedal, 1 motion, the control of shutter 8 is thrown off in first push pedal 1 under the drive of arm-tie 4, movable core,return core core puller mold insert S1 in first push pedal 1, S2, S3 is subjected to the power slip of dovetail groove direction to throw off the thread position, finish somatotype for the second time, continue the restriction that die sinking first push pedal 1 is subjected to limited screw 7, deduction 5 disengagements this moment, thereby second push pedal 2 flicks the movable core,return core core puller mold insert S4 that Angle Pin 3 drives in second push pedal, S5, S6 slides and throws off the thread position, finishes somatotype for the third time; So far, six movable core,return core core puller mold inserts have all broken away from thread back-off position, and product just can take out.

Described movable core,return core core puller mold insert S1～S6 is fixed in first, second push pedal with pressing plate and screw.

When somatotype for the third time, under the promotion of second push pedal 2, Angle Pin 3 drives movable core,return core core puller mold insert in second push pedal and slides and throw off the thread position.

Described deduction is arranged on the dynamic model, and limited screw is arranged on the cover half, and described arm-tie and first push pedal interlock make the movable core,return core core puller mold insert slip in first push pedal throw off the thread position.

Described Angle Pin is arranged in first push pedal, and second push pedal is provided with the slideway that slides for Angle Pin.
