Abstract
The utility model provides a flow channel improving structure of an injection mold. The flow channel improving structure comprises a fixed mold, wherein the fixed mold is provided with a main flow channel and a detachable main flow channel insert, and the main flow channel is arranged on the main flow channel insert. According to the flow channel improving structure provided by the utility model, with the arrangement of the detachable main flow channel insert, when the main flow channel is abrased, and the plastic forming quality is seriously influenced, the main flow channel insert can be conveniently disassembled and repaired, thus saving the time and the labor; and when the main flow channel insert is damaged, a standby main flow channel insert can be directly changed, and the whole part does not need to be replaced, thus saving materials and the cost.
Description
Technical field
The utility model relates to a kind of injection mold, particularly relates to a kind of improved flow passage structure of injection mold.
Background technology
Injection mold is used for moulded plastic products, and injection mold is installed on the injection machine, and injection machine is injected in the mould after with the melting of plastic cement pellet, and the plastic cement of melting enters through sprue, runner and forms plastic products in the mold cavity.In injection molding process, the sprue of injection mold is melted thousands of inferior the washing away, push of plastic rubber material under the environment of HTHP, damage will appear in the rear sprue that accumulates over a long period, if injury region is not repaired timely, will injection mo(u)lding go out underproof plastic products.Especially for injection mo(u)lding some during to the relatively accurate plastic product of dimensional requirement, the product disqualification rate can be very high.At present, general sprue is all integrally manufactured with mould, needs to repair if sprue damages, and just a whole set of mould must be dismantled, and repair is very difficult, and is not only consuming time but also require great effort, and is unfavorable for the raising of operating efficiency.
The utility model content
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of flow channel of injection die to improve structure, and convenient reparation to sprue improves die life, can solve the problems of the technologies described above fully.
The technical solution adopted in the utility model is:
A kind of flow channel of injection die improves structure, comprises cover half, and sprue is arranged on the cover half, and described cover half is provided with dismountable sprue mold insert, and sprue is opened on this sprue mold insert.
After the sprue damage, can dismantle separately the sprue mold insert and repair, or the sprue mold insert that directly more renews, convenient and saving cost.
As preferably, described sprue mold insert is cuboid or cylinder.
As preferably, offer the mold insert fitting recess on the described cover half, the sprue mold insert is interference fitted in this mold insert fitting recess.
As preferably, be equipped with alignment pin between sprue mold insert and the cover half.
Alignment pin can be good at locating the relative position between sprue mold insert and the cover half, makes correct position between sprue and the runner.
As preferably, the sprue mold insert adopts the Cr12MoV steel to make.
Cr
12The MoV steel has high-hardenability, and the cross section is 300-400mm
2Fully through hardening of following person still can keep good hardness and wearability in the time of 300-400 ℃, toughness is than Cr
12Steel is high, and Volume Changes is minimum during quenching.Therefore, adopt Cr
12The MoV steel is made the sprue mold insert, has good hardness and wearability, and service life is longer.
Compared with prior art, the utility model has the advantage of:
1. have dismountable sprue mold insert, when the sprue serious wear affects the plastic shaping quality, the reparation of getting off for convenience detach, time saving and energy saving.
2. the sprue mold insert adopts the high rigidity steel to make, and greatly improves the degree of anti-damage of sprue, all adopt the manufacturing of high rigidity steel and need not a whole set of mould, thereby amplitude has reduced die manufacturing cost.
3. mould all needs to heat-treat usually, and sprue mold insert volume is little, and thermal effectiveness is good, processing ease safety.
4. when the sprue mold insert damages, directly change sprue mold insert for subsequent use and get final product, will whole part replacement, economical with materials and cost.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the structural representation of another embodiment of the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Embodiment one
As depicted in figs. 1 and 2, a kind of flow channel of injection die improves structure, comprises cover half 1, and sprue 3 is arranged on the cover half 1, and described cover half 1 is provided with dismountable sprue mold insert 2, and sprue 3 is opened on this sprue mold insert 2.This sprue mold insert 2 adopts Cr
12The MoV steel are made, and are cylindrical shape.Offer the mold insert fitting recess on the described cover half 1, sprue mold insert 2 is interference fitted in this mold insert fitting recess, and between sprue mold insert 2 and cover half 1 assembling and positioning pin 4 so that 2 accurate positionings of sprue mold insert.
In the process of injection mo(u)lding, if sprue 3 damages, can dismantle separately sprue mold insert 2 and repair, or the sprue mold insert 2 for subsequent use that directly more renews, convenient and saving cost.
Embodiment two
As described in Figure 3, the difference of the present embodiment and embodiment one is that sprue mold insert 2 is rectangular shape.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (5)
