Description
Technical Field
The utility model relates to the technical field of mold, specifically be a runner size adjusting device for injection mold.
Background
When the injection molding plastic body flows from the runner to the mold forming cavity, the colloid is often extruded inwards in a fountain type and flows in the injection molding cavity in a diffusion mode, when the product is small, the colloid is directly filled in the diffusion mode basically, and the flowing direction of the colloid is random. If the flow of the injection molding body of each cavity in the multi-cavity mold is inconsistent, the size of the injection molded product is inconsistent or shrinkage is caused, which is contrary to the requirements of consistency and repeatability of industrial production.
Controlling the flow of the colloid in the injection molding cavity and considering two factors, one is the shape of the product and the other is the sprue; but the shape of the product cannot be changed by each professional mold company, and only the gate can be adjusted. Based on the above, in combination with an actual product, the applicant provides an injection mold in which the gate size can be adjusted.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a big or small adjusting device of runner for injection mold possesses simple structure, realizes the guide to the colloid flow direction when moulding plastics through adjusting runner size to try to obtain suitable flow direction, reduce because the bad advantage of the product that random diffusion flow caused, solved the problem that above-mentioned technical background provided.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a runner size adjusting device for injection mold, includes template and mould benevolence, the mounting groove has been seted up to the template bottom, mould benevolence is installed in this mounting groove, and mould benevolence with be formed with the holding chamber between the template, install the runner mold insert at this holding intracavity, be provided with runner mold insert clamp plate on the runner mold insert, the runner has been seted up to runner mold insert bottom, and still runs through in the runner mold insert and be provided with the runner, the runner is linked together with the runner, the feed inlet has still been seted up on the template, the feed inlet through the runner with the runner is linked together.
Preferably, the template is provided with a cold cutting flow passage.
Preferably, the gate insert is tapered, and one surface of the gate insert located at the gate is a smooth plane.
Preferably, the gate insert pressing plate is provided with two mounting holes, and the two mounting holes are symmetrically distributed along the central axis of the gate insert pressing plate.
Preferably, the diameter of the gate is between 0.2mm and 2 mm.
Preferably, the cross section of the feed inlet is U-shaped.
Compared with the prior art, the beneficial effects of the utility model are as follows:
1. the utility model provides a pair of a big or small adjusting device of runner for injection mold, this adjusting device overall structure is simple, reasonable in design, and convenient to use through setting up a plurality of runner mold inserts, the runner size variation on every runner mold insert realizes the guide to the colloid flow direction when moulding plastics through adjusting runner size to ask to obtain suitable flow direction, reduce because the product that random diffusion flow caused is bad.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to fig. 3, the present invention provides an embodiment: a sprue size adjusting device for an injection mold comprises a template 1 and a mold core 2, wherein a mounting groove 3 is formed in the bottom of the template 1, the mold core 2 is mounted in the mounting groove 3, a containing cavity is formed between the mold core 2 and the template 1, a sprue insert 4 is mounted in the containing cavity, a sprue insert pressing plate 5 is arranged on the sprue insert 4, two mounting holes 10 are formed in the sprue insert pressing plate 5, the two mounting holes 10 are symmetrically distributed along the central axis of the sprue insert pressing plate 5, the bottom of the sprue insert pressing plate 5 is in contact with the sprue insert 4, the top end of the sprue insert pressing plate is fixed with the mounting holes 10 through fasteners, a sprue 6 is formed in the bottom of the sprue insert 4, a sprue runner 7 is arranged in the sprue insert 4 in a penetrating manner, the sprue runner 7 is communicated with the sprue 6, and a feed inlet 8 is formed in the template 1, the feed inlet 8 is communicated with the sprue 6 through a sprue runner 7, and the cross section of the feed inlet 8 is U-shaped, so that colloid can flow conveniently.
Specifically, the template 1 is provided with a cold cutting flow passage 9.
Specifically, the gate insert 4 is conical, and one surface of the gate insert 4 located on the gate 6 is a smooth plane.
Specifically, the diameter of the gate 6 is between 0.2mm and 2mm, in this embodiment, the diameter of the gate 6 is 0.5mm, and in other embodiments, the gates 6 with different sizes are selected according to the size of the product, so as to guide the flow direction of the colloid during injection molding, so as to obtain a proper flow direction, and reduce product defects caused by random diffusion flow.
The working principle is as follows: the utility model discloses in operation, at first select the runner 6 size of looks adaptation with it according to the size of different products, later install runner mold insert 4 in the holding intracavity that template 1 and mould benevolence 2 formed, pour into the colloid into by feed inlet 8, the colloid reaches the purpose of moulding plastics by runner 7 in the runner mold insert 4 in through runner 6 gets into mould benevolence 2.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
