Abstract

The utility model provides an injection mold using a gap type inclined ejector pin ejecting mechanism, which comprises a movable mould, a movable mould cavity, a stationary mould, a stationary mould cavity, and an inclined ejector pin ejecting mechanism. A gap is arranged on the movable mould and the movable mould cavity, the inclined ejector pin ejecting mechanism comprises an inclined ejector pin and a guide block, the inclined ejector pin is threaded in the guide block, to ensure the inclined ejector pin keep the gap state with the gap position in the ejecting and resetting process of the inclined ejector pin. The injection mold using a gap type inclined ejector pin ejecting mechanism greatly decreases the processing difficulty and the requirement to the processing equipment, the waste of the material can be reduced at the same time, and the manufacture cycle is reduced.

Description

Use the injection mold of empty avoiding formula oblique top pin ejecting mechanism
[technical field]
The utility model relates to a kind of injection mold, particularly relates to the injection mold that uses oblique top pin mechanism.
[background technology]
Injection mold is to use a kind of very widely mould in the present industrial production, and its structure mainly comprises cover half 1, cover half benevolence 2, dynamic model 3, mavable module core 4, ejection system 5 as shown in Figure 1.For producing the comparatively complicated plastic cement products of some structures, corresponding die structure also can be complicated, ejection system tends to adopt oblique top pin ejecting mechanism in this case, and oblique top pin ejecting mechanism is made up of oblique top pin 6, slider guide 7, face needle plate 8, end needle plate 9 etc.Eject in the process at plastic cement products, the distance that oblique top pin 6 gos deep into plastic cement products 10 glue bit positions is L11, ejection system move in the opposite direction along die sinking side L22 apart from the time, the oblique top pin is then along the vertical direction of the die sinking direction L33 distance of moving, as long as guarantee ejection system motion L22 apart from the time, L33 gets final product greater than L11, and promptly the oblique top pin gos deep into the distance of product glue bit position along the distance of die sinking direction movement in vertical direction greater than the oblique top pin, can guarantee the smooth depanning of product like this.
The long or bigger situation in angle of inclination for some oblique top pin length, if also adopt general oblique top needle construction, then can bring difficulty to Mould Machining, because the oblique top pin is to be assemblied in the oblique top pin hole of dynamic model, mavable module core, and oblique top pin other faces and oblique top pin hole except that moulding section are all fitted, the oblique top hole can not directly mill out with milling machine, need carry out the large tracts of land line to dynamic model and mavable module core cuts, so both need to use the equipment of superior performance, and can cause the huge waste of material and the prolongation of manufacturing cycle again.
[utility model content]
Technical problem to be solved in the utility model provides a kind of injection mold that uses empty avoiding formula oblique top pin ejecting mechanism, guarantee at oblique top pin longer dimension or angle of inclination when big, make mould can easier process, assemble, reduce the waste of material, shorten the manufacturing cycle.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of injection mold that uses empty avoiding formula oblique top pin ejecting mechanism, comprise dynamic model, mavable module core, cover half, cover half Renhe oblique top pin ejecting mechanism, described dynamic model and mavable module core are provided with clearance position, described oblique top pin ejecting mechanism comprises oblique top pin and guide pad, this oblique top pin is located in this guide pad, and makes this oblique top pin keep empty avoiding state in neutralize this clearance position of the process that ejects and reset.。
Under the situation that satisfies mould strength and structural requirement, clearance position size assurance oblique top pin is not interfered with this clearance position in the process that ejects and reset all the time.
Its further comprise the oblique top needle guide to guide pad, this guide pad is fixedly connected on the dynamic model, guide pad is provided with pilot hole, the oblique top pin is located in the pilot hole and can be free to slide along the hole direction of principal axis.
The beneficial effects of the utility model: the structure that replaces existing oblique top pin hole by the clearance position of on dynamic model and mavable module core, milling, avoided the line of dynamic model to cut, the line that has reduced mavable module core cuts, and greatly reduces difficulty of processing, reduce the waste of material simultaneously, shorten the manufacturing cycle.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 uses the injection mold cutaway view of oblique top pin ejection system for prior art;
Cutaway view when Fig. 2 uses the injection moulding of empty avoiding formula oblique top pin ejection system to finish as yet not die sinking for the utility model;
Fig. 3 is the empty avoiding formula oblique top pin that uses in the utility model and the structural representation of guide pad;
Fig. 4 separates the cutaway view when product does not begin to eject as yet fully for the utility model uses the injection mold active and inactive mold of empty avoiding formula oblique top pin ejection system;
Cutaway view when Fig. 5 uses the injection mold of empty avoiding formula oblique top pin ejection system that plastic cement products is ejected fully for the utility model;
[specific embodiment]
Please refer to Fig. 2, the utility model comprises dynamic model 10, mavable module core 11, cover half 12, cover half benevolence 13 and the oblique top needle system of being made up of oblique top pin 14, slider guide 15, face needle plate 16, end needle plate 17.Wherein, be respectively equipped with clearance position 18,19 on dynamic model 12 and the mavable module core 13, make oblique top pin 14 pass this clearance position 18,19, and can be in the process that ejects and reset and dynamic model 12, mavable module core 13 empty avoidings.Because the size of oblique top pin hole when the size of clearance position is greater than not empty avoiding in the prior art in the utility model, and clearance position is straight in the utility model, can be directly mill out, thereby avoid line to cut, greatly reduce the production difficulty and the requirement of production equipment with milling machine.
Please in the lump with reference to figure 3, the utility model has not had the guide effect of oblique top pin hole, need realize guide function by the sealing position at oblique top pin 14 tops and the guide pad 20 of bottom.The size of this sealing position is generally about 3 times of oblique top needle end part sectional dimension; This guide pad is to be fixedly connected on the dynamic model by screw hole 21 or alternate manner, and guide pad is provided with pilot hole, and the oblique top pin is located in the pilot hole and can be free to slide along the hole direction of principal axis, thereby realizes the guiding to the oblique top pin.This oblique top pin bottom is provided with draw-in groove 22, and is connected on the tilted footstock by this draw-in groove, and this oblique top pin bottom is provided with hanging platform and tilted footstock is used, and tilted footstock is fixed on the end needle plate by screw.
Please refer to Fig. 4 and Fig. 5, Fig. 4 is that this novel cover half, dynamic model separate fully, the state diagram when product does not eject as yet, and Fig. 5 is the state diagram of product when ejecting fully, die sinking powered ejector retainner plate during die sinking drives the oblique top pin product is ejected; During matched moulds, release link (in the schematic diagram expression) promotes ejector retainner plate, drives the oblique top pin and resets, and finishes the die sinking mould assembling action, whole eject with reseting procedure in, the oblique top pin is in the empty avoiding state with dynamic model and mavable module core all the time at the clearance position place of dynamic model, mavable module core.
