Abstract
The utility model relates to a sprue bushing structure of a plastic injecting mould, comprising a cylinder bushing body, one end part of which is provided with a round table along the radial direction, and the round table is integrated with the cylinder bushing body into one body and protrudes outwards for forming a step, and an axle center at the other end part of the cylinder bushing body is opened with a cone-shaped punching hole, the upper part of which is big and the lower part thereof is small; a plurality of claws which are parallel to the outer wall of the cylinder bushing body and integrated into one body with the outer wall of the cylinder bushing body for locating hardware are arranged on the inner wall of the cone-shaped punching hole along circle-center direction. Any side of the circular table is cut along the penetrating part with the cylinder bushing body for forming a straight side. A pouring head of the sprue bushing structure is that: a plurality of the claws are arranged in the cone-shaped punching hole in an protruding way and press the hardware at the position of the pouring head for leading the hardware to be reliably located, thus ensuring the top surfaces of the hardware at the edge and at the center to at the same plane and leading product quality to have no fluctuation.
Description
Technical field
The utility model relates to a kind of sprue bush structure of plastics injection mould.
Background technology
See also Fig. 5, shown in Figure 6, known sprue bush structure radially is provided with its one by a cylinder body 1, one end end and outwards protrudes out round platform 2 to form step, is positioned at the conical perforations 3 ' that the round platform 2 one side direction other ends enlarge gradually along cylinder body 1 and forms.Use this structure, owing to be placed on the handware at cast gate place owing to lack constraint reliably, the situation of handware deflection appears in regular meeting in the actual production, causes deterioration in quality.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provide a kind of cast gate is designed to be convexly equipped with in the conical hole several claws, this claw is pushed down the handware at cast gate place and is made its reliable location, the five metals sheet that guarantees the edge and the end face of the handware at center at grade so that product quality does not have the sprue bush structure of the plastics injection mould that fluctuates.
The purpose of this utility model can reach by following measure:
The sprue bush structure of this plastics injection mould, comprise that a cylinder body, one end end radially are provided with its one and outwards protrude out to form the round platform of step, its special character is: the axle center along cylinder body other end end offers greatly, little cone-type piercer down, and this cone-type piercer inwall is provided with the claw that some and one parallel with the external wall of cylindrical sleeve are used to locate handware to center of circle direction.
The purpose of this utility model can also reach by following measure:
Arbitrary edge of described round platform passes through the position mutually with the cylinder body and cuts to form a straight flange.
The utility model has following advantage compared to existing technology:
1, use this sprue bush structure after, can guarantee that the handware location at cast gate place is reliable, product quality is fluctuation not.
2, the end face that has guaranteed the handware at the five metals sheet at edge and center is same plane, makes not deflection of handware.

The specific embodiment.
The utility model is further described below in conjunction with accompanying drawing:
See also Fig. 1～shown in Figure 4, the sprue bush structure of described plastics injection mould, comprise that a cylinder body 1, one end end radially are provided with its one and outwards protrude out to form the round platform 2 of step 21, axle center along cylinder body 1 other end end offers greatly, little cone-type piercer 3 down, and these cone-type piercer 3 inwalls are provided with the claw 31 that some and one parallel with cylinder body 1 outer wall are used to locate handware to center of circle direction.Arbitrary edge of described round platform 2 passes through the position mutually with cylinder body 1 and cuts to form a straight flange 22.
During use, by hand handware 4 is placed in the mould before the mould matched moulds, behind the mould matched moulds on preceding internal mold 5, the claw 31 of sprue bush is installed with the position of cast gate dead in line is pushed down handware 4, during injection mo(u)lding, the plastics of fusion flow into sprue bush and then flow into die cavity from the big cast gate of front mould 5, and handware 4 is wrapped in wherein, after the plastic cool handware 4 are fixed in the product.Then by the ejecting mechanism of mould under the top rod driving of injection machine, cooled product is ejected from mould, finish the one-shot forming process.Eject product after the cooling and remove cast gate, promptly obtain the product that needs.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
Claims (2)
1, a kind of sprue bush structure of plastics injection mould, comprise that a cylinder body, one end end radially are provided with its one and outwards protrude out to form the round platform of step, it is characterized in that: the axle center along cylinder body other end end offers greatly, little cone-type piercer down, and this cone-type piercer inwall is provided with the claw that some and one parallel with the external wall of cylindrical sleeve are used to locate handware to center of circle direction.
2, according to the sprue bush structure of the described plastics injection mould of claim 1, it is characterized in that: arbitrary edge of described round platform passes through the position mutually with the cylinder body and cuts to form a straight flange.
