Plastic elbow mould pull rod inner pumping mechanism

Abstract

The invention discloses a plastic elbow mould pull rod inner pumping mechanism. The plastic elbow mould pull rod inner pumping mechanism comprises a mold cavity installed on a mould die carrier, wherein the cavity body of the mold cavity is provided with an elbow core, the elbow core can drive a loose core through a loose core oil cylinder, and the loose core oil cylinder is fixed on an oil cylinder plate; the oil cylinder plate is installed on the mould die carrier. The plastic elbow mould pull rod inner pumping mechanism is characterized in that the head of the elbow core is connected with a guide sloping block through an oblique I-shaped groove, and the head of the guide sloping block is connected with an elbow barb core; and the elbow core is provided with a sloping block push-out spring, the sloping block push-out spring is connected with a supporting block, the supporting block is contacted with the rear end part of the guide sloping block, the rear part of the guide sloping block is connected with a sloping block pull rod, and the other end of the sloping block pull rod is connected with the oil cylinder plate. The scheme adopts a pull rod to fix the sloping block, the reset action is stable and reliable, and a cavity body is not damaged.

Description

technical field [0001] The invention relates to an inner drawing mechanism of a pull rod of a plastic elbow mold, which belongs to the field of plastic molds. Background technique [0002] In the existing technology, plastic molds are used to produce plastic elbows. When the core of the elbow is pulled out and demoulded, because the elbow has a barb, the combination of the guide inclined block, the barb core and the elbow core is generally used. The secondary core-pulling method, but when the core is pulled, the guide ramp block and the barb core will jump, and when the guide ramp block and the elbow core are reset, the guide ramp block is reset by the spring, and the elbow The core is reset by the core-pulling oil cylinder, and there is a case of asynchronous reset, which is easy to touch the cavity of the cavity and damage the cavity. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide an ...
