Abstract

The utility model discloses a die, in particular to a main runner free super high taking die with a runner lock pin. The die comprises a fixed die and a moving die matched with the fixed die, wherein the fixed die comprises a fixed die mounting plate positioned at the upper part, a heat-runner plate and a gating material unloading plate connected with the fixed die in sequence, and a fixed die plate positioned below the gating material unloading plate, and the die cavity for forming workpieces in the fixed die plate is communicated with the hot runner on the heat-runner plate and the gating material unloading plate. The die is characterized in that a runner lock pin fixing plate is fixed on the heat-runner plate; a runner lock pin retaining plate is fixed on the inner side of the gating material unloading plate; the upper pin cap of the runner lock pin is positioned in the groove on the runner lock pin fixing plate; the runner lock pin extends downwards from the hole on the runner lock pin retaining plate, and the pin head is positioned in a pin head cavity; and the pin head cavity is communicated with the pouring head on the fixed die plate, and the pin head takes the shape of an inverted cone. When the fixed die and the moving die are opened, the gating material cut in the pouring head can be automatically taken out due to the runner lock pin, thereby resulting in conveniences, integral simple structure, and flexible and reliable actions.

Description

Has the no sprue superelevation delivery tool that draws the material pin

Technical field

The utility model relates to a kind of mould, and particularly a kind of have a no sprue superelevation delivery tool that draws material pin.

Background technology

The plastic products that with the resin are raw material are adding man-hour, adopt the mold injects moulding more, and traditional hot runner mould does not produce the cast gate material, because the hot flow path self structure is limit, it is too much to peek; Perhaps adopt Accu-Valve hot flow path form, the hot flow path cost is extremely expensive.Traditional mould with pin point gate can produce a large amount of cast gate material again when peek is a lot of, cause resin waste; And the mould planar dimension also can be very big.Therefore, cold and hot in conjunction with super many deliverys tool, the high peek of little tonnage equipment mould is achieved.But must draw materials device that the cast gate material is limited, with smooth taking-up cast gate material.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, get the cast gate material and have the no sprue superelevation delivery tool that draws material pin easily, overcome the deficiencies in the prior art.

Of the present utility model have a no sprue superelevation delivery tool that draws material pin, comprise cover half and the dynamic model that matches with cover half, described cover half comprises the cover half installing plate 1 that is positioned at the top, the heat flux plates 2 that is connected successively with cover half installing plate 1, unload cast gate flitch 3 and be positioned at the solid plate that unloads cast gate flitch 3 belows, there is the die cavity that forms workpiece to be connected in the solid plate with heat flux plates 2 and the hot flow path 4 that unloads on the cast gate flitch 3, it is characterized in that: be fixed with on the described heat flux plates 2 and draw material pin fixed head 5, unloading cast gate flitch 3 inboards is fixed with and draws material pin holding plate 6, draw the last square cotter cap 10 of material pin 7 to be positioned at the groove that draws on the material pin fixed head 5, draw material pin 7 to be positioned at pin head cavity 8 downwards from drawing hole on the material pin holding plate 6 to stretch out and selling 9, pin head cavity 8 is connected with cast gate on the solid plate, and described pin head 9 is inverted cone shape.

Of the present utility model have a no sprue superelevation delivery tool that draws material pin, when dynamic model and cover half die sinking, owing to draw the material pin, can make to be breaking at the interior cast gate material of cast gate and to take out automatically, and very convenient, overall structure is simple, and flexible movements are reliable.

Description of drawings

Fig. 1 is the structural representation of the utility model specific embodiment;

Fig. 2 is an A portion enlarged drawing shown in Figure 1;

Fig. 3 is the structural representation that draws the material pin shown in Figure 1.

The specific embodiment

As shown in Figure 1, 2, 3: this mould comprises the cover half that is positioned at the top and is positioned at the dynamic model of below, cover half comprises the cover half installing plate 1, the heat flux plates 2 that is connected successively with cover half installing plate 1 that are positioned at the top, unloads cast gate flitch 3 and be positioned at the solid plate that unloads cast gate flitch 3 belows, the die cavity that forms workpiece is arranged in the solid plate, this die cavity is connected with heat flux plates 2 and the hot flow path 4 that unloads on the cast gate flitch 3.Draw material pin fixed head 5 by bolting on the heat flux plates 2, unloading cast gate flitch 3 inboards is fixed with and draws material pin holding plate 6, draw the last square cotter cap 10 of material pin 7 to be positioned at the groove that draws on the material pin fixed head 5, draw material pin 7 to be positioned at the pin head cavity 8 that draws on the material pin holding plate 6 downwards, sell head cavity 8 and be connected with cast gate on the solid plate from drawing hole on the material pin holding plate 6 to stretch out and sell 9.Wherein the side of pin 9 is inverted cone shape.

During work, melt shape raw material is full of Workpiece shaping chamber and cast gate and pin head cavity 8, by shearing device cast gate material in the cast gate and shaping workpiece are cut off before the die sinking, exist owing to drawing material to sell 7 during die sinking, draw material pin 7 terminations that the pin 9 of inverted cone shape is arranged, utilize pin 9 to pull out and promptly take out the cast gate material, very convenient.
