Abstract

The utility model relates to a mould frame, comprising a fixed die and a moving die. A groove 1 used for putting a die core is arranged on the fixed die; a groove 2 corresponding to the groove 1 and used for putting the die core is arranged on the moving die; a heave 1 is arranged in the middle of the groove 1; a limited heave is arranged on the edge of the groove 1; casting nozzles are respectively arranged on the two sides of the heave 1 on the lower part of the groove 1; a heave 2 corresponding to the heave 1 is arranged in the middle of the groove 2; a limited port corresponding to the limited heave is arranged on the edge of the groove 2. During the production process, the moving die rotates 180DEG, and the position between the fixed die and the moving die is enabled to keep invariant through an accurate locating mechanism, thereby realizing that a bichrome plastic part with long service and ideal color transition is manufactured without scratch phenomenon only by using one mould frame. By adopting the mould frame, the utility model also has the advantages of high productivity effect and low manufacturing cost at the same time.

Description

A kind of mould bases

Technical field

The utility model relates to the production parts of dual-color plastic spare, relates in particular to a kind of mould bases.

Background technology

Mould is the new high-tech product of state key encourage growth.Dual-color plastic spare has numerous outstanding representations as a kind of achievement of mature technology on the outward appearance of product, color, function.The principle of producing the mould of dual-color plastic spare is with a width of cloth cover half two width of cloth dynamic models, first in first width of cloth mold cavity injection moulding first look plastics, the not demoulding of die sinking then, cover half again with another dynamic model matched moulds, inject the second look plastics, die sinking again, finally demould.Because the guide pillar location is only adopted in the location during die change, thereby there is the scratch phenomenon in the inaccurate dual-color plastic spare that causes this method to be produced of this localization method, and service life is short, the unfavorable shortcoming of color transition.Produce a dual-color plastic spare and will employ a width of cloth cover half two width of cloth dynamic models, so production cost is higher, production efficiency is low simultaneously.

Summary of the invention

The technical problems to be solved in the utility model has provided a kind of mould bases, only needs a width of cloth cover half and a width of cloth dynamic model just can produce dual-color plastic spare, and accurate positioning is reliable when cover half and dynamic model matched moulds.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: mould bases comprises fixed half and moving half, described cover half is provided with the groove I that is used to place core rod, described dynamic model be provided be used to place core rod and with groove I corresponding groove II, be provided with protruding I in the middle of the described groove I, the edge of described groove I is provided with spacing preiection, protruding I both sides at groove I lower curtate are respectively equipped with casting gate, be provided with the protruding II of respective protrusions I in the middle of the described groove II, the edge of described groove II is provided with the limited mouth of corresponding spacing preiection.

As a kind of improvement of the present utility model, the described spacing preiection outside is provided with inclined-plane I, and described limited mouth inboard is provided with the inclined-plane II of inclined surface I.

As another kind of improvement the of the present utility model, the protruding II both sides of described groove II lower curtate are respectively equipped with the locating hole that is used to locate core rod.

After the utility model adopts technique scheme, dynamic model rotates 180 degree in the production process, guarantee that by accurate in locating mechanism the position between cover half and the dynamic model remains unchanged, thereby realizing only producing with a width of cloth mould bases does not have the scratch phenomenon, and long service life, the desirable dual-color plastic spare of color transition adopt this mould bases also to have production efficiency height, advantage that production cost is low simultaneously.

Fig. 6 is the A-A figure of Fig. 5.

The specific embodiment

As shown in Figure 1, 2, the utility model mould bases comprises a cover half 1, a dynamic model 2, dynamic model 2 is installed on the base 3, dynamic model 2 is provided with four guide pillars that are used to locate 4, cover half 1 is provided with the jack 5 of corresponding guide pillar 4, one end of guide pillar 4 is fixed on the dynamic model 2, and another inserts jack 5 and flexibly connects with cover half 1.Shown in Fig. 5,6, be provided with protruding I7 in the middle of being used to place the groove I6 of core rod in the cover half 1, projection I7 is divided into two grooves with groove I6, the cross section of groove I6 is the M type substantially, thereby can place two core rods, each bottom portion of groove is that the protruding I7 both sides of groove I6 lower curtate are respectively equipped with casting gate 8 again, and casting gate 8 directly communicates with groove I6; The edge of groove I6 is provided with spacing preiection 9, and the height of spacing preiection 9 is identical with the height of protruding I7, thereby is in same horizontal plane; Spacing preiection 9 outsides are provided with inclined-plane I10, so because spacing preiection 9 be symmetrical about two inclined-plane I constitute a V font.Shown in Fig. 3,4, dynamic model 2 also has a groove II11 who is used to place core rod, be provided with a protruding II12 corresponding in the middle of it with protruding I7, be provided with the limited mouth 13 of corresponding spacing preiection 9 at the edge, top and limited mouth 13 bottoms of projection II12 maintain an equal level, be positioned at equally on the horizontal plane, the cross section of groove II11 is the W type substantially, can place two core rods too; Be provided with inclined-plane II14 in the inboard of limited mouth 13, it and inclined-plane I14, and then about two inclined-plane II14 also become a V font, two inclined-planes just can be combined together so up and down.The protruding II12 both sides of groove II11 lower curtate are respectively equipped with the locating hole 15 that is used to locate core rod, and core rod is placed in the mould bases securely.

All be provided with two groove parts on cover half 1 and the dynamic model 2 and be used for placing core rod, spacing preiection 9 and limited mouth 13 are connected when combining up and down, projection I7 also closely links to each other with protruding II12 and then forms two independently working chambers, elder generation's injection moulding first look plastics in chamber during work, die sinking is spent matched moulds again with dynamic model 2 rotations 180 then, the injection second look plastics in another chamber, and in chamber just now injection moulding first look plastics still, die sinking just can obtain dual-color plastic spare.So repeatable operation just can be produced needed product on same mould bases.Compare with production in the past and to adopt the utility model mould bases to have production efficiency height, advantage that production cost is low.The two detent mechanisms that are made of guide pillar and inclined-plane can make the product of producing not have the scratch phenomenon, long service life, color transition ideal simultaneously for mould bases provides high-precision location.
