Description
Technical Field
The utility model relates to an injection molding device especially relates to a reducible unedged injection molding device.
Background
In the prior art, referring to fig. 1, when performing injection molding of a hardware and a plastic part, the hardware 100 needs to be installed in a mold, and after the plastic part 101 is molded in the mold, the hardware 100 and the plastic part 101 are combined into an integral structure. However, in this injection molding method, in order to facilitate insertion and removal of the hardware 100, there are generally fine gaps between the hardware 100 and the mold, but during the injection molding process, plastic is easily poured into these gaps, and after the workpiece is injection molded, vertical burrs or burrs are formed around the hardware 100, which requires further processing. In order to remove burrs or rough edges, secondary processing is generally performed manually or by using an appliance, so that the production process of the injection molding workpiece is complicated, the efficiency is low, the labor cost is high, and the production requirement is difficult to meet.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model lies in, to prior art not enough, provide a reducible burr or deckle edge, reducible manufacturing procedure, can improve production efficiency and save manufacturing cost's the device of moulding plastics.
In order to solve the technical problem, the utility model adopts the following technical scheme.
The utility model provides a reducible unedged device of moulding plastics, its is including mould and hardware, the jack has been seted up on the mould, the first end of hardware is inserted and is located in the jack, the second end of hardware is outside protruding, the lateral part of hardware is formed with outside convex shirt rim, the shirt rim surround in the hardware, the shirt rim butt in the mould, just the shirt rim cover in the edge of jack is in when plastic work piece shaping back on the mould, will the second end of hardware with the shirt rim inlays to be located in the plastic work piece.
Preferably, the hardware is cylindrical.
Preferably, the second end of hardware is formed with gear portion, gear portion inlays to be located in the plastic work piece.
The utility model discloses an injection molding device capable of reducing burrs, wherein the skirt edge surrounding the hardware is arranged at the side part of the hardware, when the hardware is inserted in a mold, the skirt edge can cover the edge of the jack, thereby shielding the gap between the hardware and the jack, after the plastic work piece is injection molded, the formation of burrs or burrs at the second end of the hardware is effectively avoided, thereby not only improving the injection molding quality of the work piece, but also avoiding the need of secondary processing, reducing the processing procedure, improving the production efficiency and saving the labor cost, in addition, because the skirt edge is simultaneously embedded in the plastic work piece, a step notch is formed at the joint of the plastic work piece and the skirt edge, and under the matching of the step notch and the skirt edge, the combination relationship between the hardware and the plastic work piece is more compact and reliable, make the hardware with plastic work piece shaping back is more firm, reliable, and then has improved the wholeness ability of work piece.

Detailed Description
The present invention will be described in more detail with reference to the accompanying drawings and examples.
The utility model discloses a reducible unedged injection moulding device combines fig. 2 to 6 to show, and it is including mould 1 and hardware 2, jack 10 has been seted up on the mould 1, hardware 2's first end is inserted and is located in the jack 10, hardware 2's second end is outside protrusion, hardware 2's lateral part is formed with outside convex shirt rim 20, shirt rim 20 encircle in hardware 2, shirt rim 20 butt in mould 1, just shirt rim 20 cover in jack 10's edge is in when plastic work piece 3 shaping back on the mould 1, will hardware 2's second end with shirt rim 20 inlays and locates in the plastic work piece 3.
In the injection molding device, the skirt rim 20 surrounding the hardware 2 is arranged on the side part of the hardware 2, when the hardware 2 is inserted into the mold 1, the skirt rim 20 can cover the edge of the insertion hole 10, so as to shield the gap between the hardware 2 and the insertion hole 10, after the plastic workpiece 3 is injection molded, burrs or burrs are effectively prevented from being formed on the second end of the hardware 2, thereby not only improving the injection molding quality of the workpiece, but also avoiding secondary processing, reducing the processing procedures, improving the production efficiency and saving the labor cost, in addition, because the skirt rim 20 is simultaneously embedded in the plastic workpiece 3, a step notch 30 is formed at the joint of the plastic workpiece 3 and the skirt rim 20, and under the matching of the notch 30 and the skirt rim 20, the combination relationship between the hardware 2 and the plastic workpiece 3 is more compact and reliable, make hardware 2 with plastic work piece 3 shaping back is more firm, reliable, and then has improved the wholeness ability of work piece.
In this embodiment, the hardware 2 is cylindrical.
Preferably, a gear portion 21 is formed at the second end of the hardware 2, and the gear portion 21 is embedded in the plastic workpiece 3. The gear part 21 can make the hardware 2 and the plastic workpiece 3 combined more tightly, so that the overall structure of the workpiece is firmer.
The utility model discloses an injection molding device inlays the course of working that the piece was glued at the hardware, and the shirt rim design of hardware is modelled, can effectively solve the deckle edge problem at hardware and plastic joint position to reduce the post-processing process, improved the production efficiency of product.
The above is only the embodiment of the present invention, and is not intended to limit the present invention, and all modifications, equivalent replacements or improvements made within the technical scope of the present invention should be included within the protection scope of the present invention.
