Specific embodiment
The present invention provides automotive safety lid bicolor injection mould.Technical solution of the present invention is carried out below in conjunction with attached drawing detailed
Description, so that it is more readily understood and grasps.
Automotive safety lid bicolor injection mould includes pedestal, the second die holder and third die holder as shown in Figures 1 to 5.
Pedestal 1 is equipped with the base station 2 for having rotation switching displacement, sets that there are two the first moulds being separately arranged on base station 2
Seat 3, the first die holder 3 are equipped with the first glue road 32 of several first type chambers 31 and any first type chamber 31 of connection.
Second die holder 4 be used between the first die holder 3 formed first time injection molding, the second die holder 4 be equipped with it is several with
The second type chamber 41 mutually matched one by one of first type chamber 31, the second die holder 4 have the shift reciprocately towards pedestal 1.
Third die holder 5 for forming second of injection molding between the first die holder 3, third die holder 5 be equipped with it is several with
The third type chamber 51 mutually matched one by one of first type chamber 31 and the second glue road 52 being connected with any third type chamber 51, third mould
Seat 5 has the shift reciprocately towards pedestal 1.
Under the rotation toggle bit shifting state of base station 2, any first die holder 3 is in the second die holder and third die holder on base station 2
Between mutually switching contraposition.After rotating switching position, station still phase exactitude position.
Specifically realize process and principle explanation:
When carrying out injection molding operation, the second die holder 4 first and the first die holder 3 carry out molding operation, carry out first time injection molding
Molding, after first time injection molding, the second die holder 4 is separated with 3 phase of the first die holder, due to the second type chamber 4 of the second die holder 4 and the
The semi-finished product contact surface of single injection-molded is more smooth, therefore the semi-finished product of first time injection molding can be bonded in the first die holder
In 3 the first type chamber 31, and the second die holder 4 is detached from.
At this point, base station carries out rotation switching displacement, so that carrying the first die holder 3 of the semi-finished product of first time injection molding
It switches to third die holder 5 with respect to position, and another first unloaded die holder 3 and the opposite position of the second die holder 4.
First time injection molding is carried out after the displacement of second die holder 4, and carries out second of injection molding after the displacement of third die holder,
First time injection molding is consistent with the above process.
When second of injection molding, third die holder 5 carries out second by the second glue road 52 and is molded, in the first die holder 3
Semi-finished product are formed by cavity with third type chamber 51 and are molded, to realize secondary injection molding, obtain double-colored compound
Moulding finished product, at this point, having been cured between moulding finished product and the first type chamber 31 of the first die holder 3, cohesive force is smaller, divides mould
Moulding finished product is located in the third type chamber 51 of third die holder 5 afterwards, carries out demoulding to the moulding in third type chamber 51.
Such cycle operation realizes the injection molding of double-deck overlaying part.
In a specific embodiment, as shown in Figure 1, pedestal 1 is equipped with the position-limit mechanism 6 for limiting to base station 2, base
Platform 2 has telescopic displacement.
It specifically describes, by position-limit mechanism 6, can ensure that the position of base station is stablized, and the telescopic displacement of base station 2 is for keeping away
The position-limit mechanism 6 is allowed to carry out position switching, it is ensured that the closing precision of double-station is reliable and stable.
In a specific embodiment, as shown in Fig. 2, third die holder 5 includes the first template 7 and the second template 8, the first mould
Plate 7 is equipped with several mould roads 71, and mould road 71 is equipped with mould road end type chamber 72 towards the end face of pedestal 1, if the second template 8 is equipped with
The free end of the dry mould column 81 corresponded in the road Chuan Jiemo 8, mould column 81 is equipped with model end 82, the road model Duan82Yu Mo end type
Chamber 72 forms third type chamber 51, and the second template has the shift reciprocately towards the first template.
It specifically describes, is displaced by the second template 8 towards the first template 7, is able to achieve the molding of third type chamber 51, formed
Second of injection mold cavity, and after second of injection molding, the second template 8 is moved away from the first template 7, so that model end 82 and note
Plastic mutually separates, and then the second template 8 is displaced again towards the first template 7, and model end 82 can eject moulding, so that injection molding
The road Jian Yumo end type chamber 72 is separated, so that automatic blanking, improves shaping efficiency.
In actual application, which is round sheet body structure, and two sides have several same respectively
The ring rib of heart circle structure, and have the recessed structure of ring to form ring rib on the first type chamber 31, second type chamber 41 is plane wall construction, because
, when the second die holder 4 is separated with the first die holder 3, being molded semi-finished product for the first time can be attached on the first type chamber 31 for this.
And in first time injection molding, the first die holder 3 carries out the injection molding of PA glue, it is between the first type chamber 41 after PA glue is cooling
Viscosity can be smaller, and third die holder 5 carries out the injection molding of EVA glue, has the recessed structure of ring in third type chamber 51, with EVA glue surface
Between viscosity it is larger, when third die holder 5 and the first die holder 3 divide mould, finished product moulding can be detained in third die holder 5, lead to
The second displacement of the second template 8 is crossed, to realize the stripping operation to moulding.
By above description it can be found that automotive safety lid bicolor injection mould of the present invention, is able to achieve double-colored soft material injection molding
The injection molding of part realizes continuous injection molding operation by way of double-station rotation switching, shortens molding cycle, and operation is efficient,
Moulding formed precision is higher, and product qualification rate is protected.Second of injection molding has automatic material separator function, without additional
Increase shedding mechanism, improve the smoothness of injection molding operation, production efficiency effectively improves, and is not easy to generate moulding de-
Material damage.Whole design is ingenious, is easy to the double-shot moulding demand of automotive safety lid, is suitable for popularization and application.
Technical solution of the present invention is fully described above, it should be noted that specific embodiment party of the invention
Formula is simultaneously not limited by the description set out above, the Spirit Essence of those skilled in the art according to the present invention structure, method or
All technical solutions that function etc. is formed using equivalents or equivalent transformation, all fall within protection scope of the present invention
Within.
