Abstract

The invention provides a screw-type push-out rotary demolding mechanism which is used for demolding a formed threaded product. The screw-type push-out rotary demolding mechanism comprises a fixed moldpart, a movable mold part, a guiding component, a pushing component, a reset component and a pushing part, wherein the fixed mold part and the movable mold part are connected and guided by the guiding component; the pushing component drives the to-be-demolded formed threaded product to demold under the action of an equipment push rod; the pushing part is used for pushing out the demolded formed threaded product; the reset spring is used for resetting the movable mold part after the formed threaded product is pushed out; and the equipment push rod is driven by forming equipment of the formed threaded product. The screw-type push-out rotary demolding mechanism is simple and compact in structure, and small in size, can realize rotary demolding ejection by a push-out force of an injection molding machine without an external power device, and is quick in demolding, reliable in mechanism, lower in mold cost and suitable for mass production.

Description

technical field

[0001] The invention relates to the technical field of mold design, in particular to a screw-type push-out rotary demoulding mechanism. Background technique

[0002] With the rapid development of domestic automobiles, home appliances, electronic communications and various building materials, it is expected that in the future mold market, the proportion of plastic molds to the total molds will still gradually increase, and the development speed will be faster than other molds, while internal thread demoulding It is one of the difficulties in plastic mold design. Generally, the automatic stripping of internal threads adopts the forced stripping structure, the external stripping structure using the movable thread mandrel, the gear, the rack mechanism or the hydraulic pressure, and the gear mechanism. For the above structure, the forced stripping has specific requirements for the plastic formed by the product. , In addition, it is easy to damage the threaded par...
