Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Referring to fig. 1-5, the present embodiment discloses a mold inner cutting mechanism for a mold gate, the inner cutting mechanism is disposed at a gate of the mold, the mold includes a moving mold 1, a fixed mold 2, an ejection assembly 3 and a feeding pipe 4; wherein movable mould 1, cover half 2 mutually support, and movable mould 1 can reciprocate relatively cover half 2, and ejection subassembly 3 sets up in the inside of cover half 2, and inlet channel 4 and mould advance jiao kou intercommunication for mould plastics to the mould is inside, and the sizing material gets into ejection subassembly 3 surface by inlet channel 4 and finally forms the product.

The inscribing mechanism may include a glue-notch insert 5 and a swage assembly 6. Referring to fig. 3, 4 and 6, the glue inlet insert 5 is disposed at the glue inlet of the moving mold 1, the bottom surface of the glue inlet insert 5 is flush with the bottom surface of the mold, the bottom of the glue inlet insert 5 is provided with an insert plate 51, and the side surface of the insert plate 51 is provided with an injection molding hole 52 matched with the injection molding glue inlet 41 of the feeding pipe 4. During injection molding, the movable mold 1 and the fixed mold 2 are assembled, and the injection molding glue opening 41 injects glue into the surface of the ejection assembly 3 from the injection molding hole 52 to form the plastic product 7.

The material pressing component 6 is arranged on the side surface of the glue opening insert 5, and the material pressing component 6 can slide up and down relative to the glue opening insert 5, namely slide along the side wall of the glue opening insert 5. And when the mold is opened, the pressing assembly 6 is separated from the ejection assembly 3 after the gate insert 5, that is, the pressing assembly 6 is firstly contacted with the ejection assembly 3 when the mold is closed, that is, in an initial state, the bottom surface of the pressing assembly 6 is lower than the bottom surface of the gate insert 5, and when the ejection assembly 3 is firstly contacted, the pressing assembly 6 starts to slide upwards against the gate insert 5 until the insert plate 51 is inserted into the ejection assembly 3 completely.

Specifically, in an initial state, the movable and fixed mold is in a mold opening state, when injection molding is required to be started, the movable and fixed mold is closed, when the insertion plate 51 is completely inserted into the ejection assembly 3, the feeding pipeline 4 starts feeding, and plastic materials flow through the injection molding glue opening 41 and the injection molding hole 52 from the feeding pipeline 4 and enter the surface of the ejection assembly 3 to form the plastic product 7. After a plastic product 7 is formed, then the mold is opened, in the mold opening process, the movable mold 1 drives the rubber opening insert 5 to move upwards, in the upwards moving process, due to the effects of the injection molding hole 51 and the material pressing component 6, the injection molding rubber opening 41 and the plastic product 7 are cut open in the upwards moving process of the insertion plate 51, in addition, due to the fact that the material pressing component 6 leaves the ejection component 3 from the rubber opening insert 5, the plastic product 7 cannot be pulled and deformed by the insertion plate 51, the separation of the plastic product 7 and the injection molding rubber opening 41 is realized, the condition that the rubber opening is unstably treated by the plastic mold twice is avoided, and the labor and jig input cost are effectively saved.

Referring to fig. 2, the pressing assembly 6 includes an ejector block 61, a mounting plate 62, and a spring 63. The ejection block 61 is slidably connected to the side surface of the glue opening insert 5, before mold closing, the bottom surface of the ejection block 61 is flush with the bottom surface of the insertion plate 51, a gap for sliding the ejection block 61 is formed in the movable mold 1, the mounting plate 62 is arranged at the top of the ejection block 61, the spring 63 is arranged at the top of the mounting plate 62, and during mold opening, the ejection block 61 leaves the ejection assembly 3 after the glue opening insert 5 under the elastic force of the spring 63. During mold closing, the elastic ejecting block 61 contacts the ejecting assembly 3 and starts to move upwards, at the moment, the spring 63 contracts to accumulate elastic force, during the mold opening process, due to the effect of the elastic force, the elastic ejecting block 61 can always press the plastic product 7 at the initial stage of mold opening, and when the inserting plate 51 is completely pulled away from the ejecting assembly 3, namely when the inserting plate 51 completely cuts the plastic product 7 and the injection molding glue opening 41, the elastic ejecting block 61 starts to move upwards, so that the mold opening action is completed.

Referring to fig. 2 and 5, the ejection assembly 3 includes an ejection rod 31 and an ejection block 32. The ejector rod 31 is arranged inside the fixed mold 2, the ejector block 32 is arranged on the top of the ejector rod 31, and the top of the ejector block 32 is provided with a slot 321 matched with the insertion plate 51. Preferably, the ejector rod 31 is fixedly connected with the ejector block 32 through screws, so that the problems of deformation caused by too long ejector block 32 and difficulty in disassembling and maintaining the ejector block 32 are effectively solved, and the ejector block can be disassembled and maintained from the surface of the mold through a screw fixing mode.

Through the technical scheme, the utility model discloses a mould jiao kou mould inscription mechanism, this mechanism is through jiao kou mold insert 5 and the cooperation of pressing material subassembly 6, presses material subassembly 6 to push down plastic product 7, takes out gluey kou mold insert ejecting subassembly 3 through moving the cover half die sinking outside to make jiao kou mold insert 5 with plastic product 7 with advance the separation of moulding plastics mouth 41, avoided the plastic mould secondary treatment to glue the condition that there is the instability in the mouth, effectively saved manual work and tool input cost.
