Abstract
The utility model discloses a travel limiting mechanism for an injection mold. The travel limiting mechanism for an injection mold comprises a fixed mold holder (1), a fixed mold base plate (2), a fixed mold plate (3), a movable mold plate (4), a movable mold base plate (5) and a movable mold holder (6), wherein a guiding sleeve (7) is mounted in the fixed mold plate (3); a guiding column (8) is mounted in the movable mold plate at a position corresponding the guiding sleeve (7). The mechanism is characterized in that a stripper bolt (9) is mounted in the fixed mold holder (1); the stripper bolt (9) penetrates through the fixed mold base plate (2) and the fixed mold plate (3); a pulling rod (10) penetrates through the movable mold plate (4) and the movable mold base plate (5); the stripper bolt (9) is in threaded connection with the pulling rod (10); the stripper bolt (9) and the pulling rod (10) can move back and forth in a mold together. According to the travel limiting mechanism for the injection mold provided by the utility model, through arranging a travel limiting mechanism on the movable mold directly, travel control of the movable mold can be realized, injection moldings of a plurality of colors and a plurality of textures are completed, defects that the existing traditional mechanism requires larger reformation on an injection machine and the cost is high are avoided, and the whole device is simple in structure and low in construction cost.
Description
Technical field
The utility model belongs to forming materials field, specifically just relates to injection molded field, especially relates to the position-limit mechanism that can control injection mold dynamic model opening stroke.
Background technology
Injection molded is a kind of important means of product shaping, injection molded is to utilize the plastic material principle that shape changes under HTHP, use plastic mould various plastic materials to be made into the process of the needed product of people, in general, plastic mould is the built-up plastics mould for compression moulding, extrusion molding, injection, blowing and low foaming, it mainly comprises dynamic model, cover half and core rod, on dynamic model and cover half, is equipped with die cavity, and core rod is housed in die cavity.Existing common plastic mould is all to form after injecting plastic mould by injection machine after the melting of plastic cement raw material, then by the guiding mechanism in injection mold, dynamic model is separated with quiet mould, thereby product is taken out from injection moulding die cavity.
Along with the development of injection molding technology, modern injection moulding can complete the injection mo(u)lding of multiple color and different plastic cement material products in a mold, conventionally in the time of the plastic cement products of this multiple color of injection moulding and material, need to complete by mould opening stroke position-limit mechanism is set in injection mold, existing journey stop gear is all by adding that in the original program of injection machine Stroke Control program controls, need to transform by a relatively large margin existing injection machine, cost is higher.
Utility model content
The purpose of this utility model be for existing injection machine in multiple color and various material injection molding process, the technological deficiency that need to transform original injection machine, a kind of injection mold journey stop gear is provided, journey stop gear is directly set on dynamic model, just can realize the control to die stroke, complete multiple color and various material injection mo(u)lding.
Technical scheme
In order to realize above-mentioned technical purpose, the present invention designs a kind of injection mold journey stop gear, it comprises cover half seat, cover half backing plate, solid plate, moving platen, dynamic model backing plate and dynamic model seat, guide pin bushing is contained in solid plate, guide pillar is arranged in moving platen and guide pin bushing correspondence position, it is characterized in that: in described cover half seat, unloading bolt is housed, unloading bolt is through cover half backing plate and solid plate, pull bar is through moving platen and dynamic model backing plate, unloading bolt is connected with pull rod screw, and unloading bolt can move back and forth together with pull bar in mould.
Described guide pillar uses screw lock on dynamic model backing plate.
Described rod outer sleeve has spring, and spring is contained in solid plate spring groove.
Described unloading bolt is sleeved in lower link bar.
Beneficial effect
A kind of injection mold journey stop gear that the utility model provides directly arranges journey stop gear on dynamic model, just can realize the control to die stroke, completes multiple color and various material injection mo(u)lding.Avoid existing traditional mechanism to transform by a relatively large margin injection machine, defect with high costs, whole apparatus structure is simple, low cost.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
As shown in Figure 1, a kind of injection mold journey stop gear, it comprises cover half seat 1, cover half backing plate 2, solid plate 3, moving platen 4, dynamic model backing plate 5 and dynamic model seat 6, guide pin bushing 7 is contained in solid plate 3, guide pillar 8 is arranged in moving platen 4 and guide pin bushing 7 correspondence positions, it is characterized in that: in described cover half seat 1, unloading bolt 9 is housed, unloading bolt 9 is through cover half backing plate 2 and solid plate 3, pull bar 10 is through moving platen 4 and dynamic model backing plate 5, unloading bolt 9 and pull bar 10 are threaded, and unloading bolt 9 can move back and forth together with pull bar 10 in mould.
Described guide pillar 8 use screw locks are on dynamic model backing plate 5.
Described pull bar 10 overcoats have spring 11, and spring 11 is contained in solid plate 3 spring grooves.
Described unloading bolt 9 is sleeved in lower link bar 12.
A kind of injection mold journey stop gear that the utility model provides directly arranges journey stop gear on dynamic model, just can realize the control to die stroke, completes multiple color and various material injection mo(u)lding.Avoid existing traditional mechanism to transform by a relatively large margin injection machine, defect with high costs, whole apparatus structure is simple, low cost.
