Abstract

The utility model discloses an injection mold, which comprises a cover die and a moving die arranged correspondingly to the cover die, wherein the moving die comprises a moving die plate, a mold core positioned on the moving die plate, a spring, a slide block and a limit structure; the spring is arranged between the moving die plate and the slide block; the slide block is movably arranged on the moving die plate, and the slide block is provided with a foot groove; the mold core of the moving die, the slide block and the cover die can be enclosed to form a mold cavity; the slide block moves relative to the moving die plate through the action of the cover die and the spring; and the limit structure can limit the motion of the slide block. In opening mold, the slide block moves a certain distance under the action of the spring to push products away from the moving die plate, thereby enabling users to take products from the moving die. The injection mold has the advantages of having simple structure and reducing production cost.

Description

Injection mold

Technical field

The utility model relates to a kind of mould, relates in particular to an injection mold.

Background technology

In the injection mold field, under the situation of the comparatively complicated plastic product of forming shape, during the plastic product demoulding, some part of product is easy to because of be out of shape by brute force.

The lower extending part that a kind of injecting products has base portion, extend downwards from base portion and extend laterally the oblique pin of side direction of formation from lower extending part, injecting products often need adopt the oblique pin of slide block mechanism assistant formation side direction on injection mold when moulding.

Yet the position that slide block mechanism takies on injection mold is bigger, thereby makes the size of injection mold strengthen, and has increased production cost.

The utility model content

The purpose of this utility model is to provide a kind of injection mold simple in structure, lower-cost.

For achieving the above object, injection mold that the utility model provides is used for the moulding injecting products.Injection mold comprise a cover half and one with the dynamic model of the corresponding setting of cover half, this dynamic model comprises that a moving platen, is installed in core, spring, sliding shoe and the position limiting structure on the moving platen, spring is located between moving platen and the sliding shoe, sliding shoe is installed on the moving platen movably, and sliding shoe is provided with a pin groove; The core of dynamic model, sliding shoe can be enclosed die cavity with cover half, and sliding shoe is moving platen activity relatively by the effect of cover half and spring, and position limiting structure can limit the activity of sliding shoe.

As mentioned above, the utility model injection mold is when die sinking, and sliding shoe moves a certain distance under the effect of spring and product is pushed away moving platen, thereby product can be taken off from dynamic model, thereby the utility model is simple in structure, can reduce production costs.

As further improvement, offer containing hole on the moving platen; Described sliding shoe upper surface is concaved with a holding hole, be concaved with a connecting hole on this holding hole diapire, position limiting structure one end passes holding hole, connecting hole and containing hole and is fixed on the moving platen, and described spring housing is located on this position limiting structure and is contained in this containing hole.

Position limiting structure is a stop screw.

The sliding shoe lower surface is concaved with an accepting hole that is connected with connecting hole, and described spring one end is installed in this accepting hole.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1 to Fig. 3, the utility model injection mold 1 comprise a dynamic model 10 and one with the cover half 20 of dynamic model 10 corresponding settings.

Described dynamic model 10 comprises that a moving platen 11, is installed in core 12, some springs 13, some push rods 14, a sliding shoe 15 and at least one position limiting structure on the moving platen 11, in the present embodiment, this position limiting structure is a stop screw 16, offer some containing holes 111 on the moving platen 11, sliding shoe 15 upper surfaces are concaved with a holding hole 151, be concaved with a connecting hole 152 on these holding hole 151 diapires, sliding shoe 15 lower surfaces are concaved with an accepting hole 153, and this accepting hole 153 is connected with connecting hole 152.Upper end, sliding shoe 15 left sides is provided with the pin groove 154 of an oblique pin shape.Spring 13 is installed in the containing hole 111 of moving platen 11, stop screw 16 mobilizable being fastened in the holding hole 151, spring 13 is sheathed on this stop screw 16, this stop screw 16 passes connecting hole 152, accepting hole 153 and containing hole 111 and is fixed on the moving platen 11, and spring 13 is contained in the accepting hole 153 and spring 13 1 ends are resisted against accepting hole 153 diapires.

During injection mold 1 matched moulds, described cover half 20 is enclosed die cavity with moulding injecting products 80 with core 12, the sliding shoe 15 of dynamic model 10, and injecting products 80 has base portion 81, the lower extending parts 82 that extend downwards from base portion 81 and the oblique pin 83 of side direction that extends laterally formation from lower extending part.Push rod 14 passes moving platen 11 and core 12 is resisted against injecting products 80 inwalls.

See also Fig. 2, during injection mold 1 die sinking, cover half 20 separates with dynamic model 10, sliding shoe 15 upsprings under the effect of spring 13 from a segment distance simultaneously, when the end face of stop screw 16 is connected to holding hole 151 diapires, sliding shoe 15 stop motions, and the oblique pin 83 of the side direction of injecting products 80 has broken away from core 12, thus make the space that when next step push rod 14 ejects, has injecting products 80 distortion.

See also Fig. 3, after the oblique pin of the side direction of injecting products 80 83 breaks away from cores 12, promote push rod 14 by injection machine (figure does not show) and replace injecting products 80 and the pin groove 154 of the oblique pin 83 of the side direction of injecting products 80 from sliding shoe 15 ejected.

As mentioned above, the utility model injection mold 1 is when die sinking, sliding shoe 15 moves a certain distance under the effect of spring 13 and the lower extending part 82 and the oblique pin 83 of side direction of injecting products 80 is pushed away moving platen, thereby injecting products 80 can be taken off from dynamic model 10, thereby the utility model is simple in structure, can reduce production costs.

The utility model is not limited to the above-mentioned specific embodiment, those skilled in the art that also can make multiple variation in view of the above, only be installed on the moving platen or only be installed in the sliding shoe as spring, these variations all should be covered by in the scope of the utility model claim.
