Abstract
The utility model relates to a rotary type throttle valve, which comprises flow channel slots, a polygonal hole and a wave bead locating slot. Three flow channel slots are arranged at the top end of the throttle valve, the three flow channel slots are distributed in a T shape, two flow channel slots are in linear connection, and the other flow channel slot is vertical and is connected with the two flow channel slots; the polygonal hole is arranged at the point of intersection of three flow channels; and when two products are needed to be injection-molded, the polygonal hole is rotated to enable flow channels on the left side and the right side of a movable mold core to be communicated with the two flow channel slots linearly connected on the throttle valve. When one product is needed to be injection-molded, the polygonal hole is rotated to enable the flow channel slot vertically arranged on the throttle valve to be communicated with the flow channel on the mold core at the other side of an injection-molding product. The wave bead locating slot on the throttle valve plays a role of positioning the rotating throttle valve. The rotary type throttle valve is simple in structure and low in cost, and can not be damaged easily, the fabrication process is optimized while the product quality is ensured, and the follow-up maintenance is simpler and more convenient.
Description
Technical field
The utility model relates to the injection mold field, particularly a kind of rotary throttle valve.
Background technology
Existing injection mold field often has the situation of the common injection moulding of two products, but sometimes, only needs the single product in the injection mold again.For this problem, usually adopt the method for changing mold insert in the prior art: make a plurality of mold inserts, include the mold insert of runner and do not have the mold insert of runner; When wanting two products of injection moulding, be placed with the mold insert of runner; When needs injection moulding wherein during a mould product, original product runner mold insert is more changed.
Adopt said method to bring following problem through regular meeting: 1, increase and join mould difficulty (need repeatedly join mould), mold insert is lost easily, causes the increase of labour cost and Master Cost.
2, field operation personnel's professional knowledge is had relatively high expectations.Be easier to cause mould to damage, increase the expense that repairs a die.
The utility model content
Technical problem to be solved in the utility model provides a kind of rotary throttle valve, and this kind structure can realize wherein single product of multi-imprssion mould tool injection moulding.When guaranteeing product quality, optimized manufacture craft, made follow-up maintenance simpler more convenient.
The technical scheme that its technical problem that solves the utility model adopts provides a kind of rotary throttle valve, comprise flow path groove, polygonal hole, rotary throttle valve integral body is cylinder, there are three flow path grooves on the top of choke valve, these three flow path grooves are T-shaped and distribute, wherein two flow path grooves point-blank, another flow path groove is vertical and connect above-mentioned two flow path grooves; There is a polygonal hole at the intersection point place of three flow path grooves.
The rotary throttle valve bottom has three ripple pearl locating slots, and the angle of the ripple pearl locating slot in the middle of being positioned at and the line of centres and other two the ripple pearl locating slots and the line of centres is 90 degree.
Beneficial effect
1, the utility model can be realized wherein single product of multi-imprssion mould tool injection moulding, has optimized manufacture craft when guaranteeing product quality, makes follow-up maintenance simpler more convenient.
2, the utility model is simple in structure, and is not fragile, and cost of manufacture is cheap.

Fig. 2 is the utility model front view.
Fig. 3 is the utility model side view.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of rotary throttle valve, comprise flow path groove 1, polygonal hole 2, rotary throttle valve integral body is cylinder, there are three flow path grooves 1 on the top of choke valve, these three flow path grooves 1 are T-shaped and distribute, wherein two flow path grooves point-blank, another flow path groove is vertical and connect above-mentioned two flow path grooves; There is a polygonal hole 2 at the intersection point place of three flow path grooves 1.
The rotary throttle valve bottom has three ripple pearl locating slots 3, and the angle of the ripple pearl locating slot in the middle of being positioned at and the line of centres and other two the ripple pearl locating slots and the line of centres is 90 degree.
When two products of needs injection moulding, the runner of the right and left on the dynamic mould core is communicated with two flow path grooves that linearly connect on the choke valve.
When only needing one of them product of injection moulding, rotate polygonal hole 2, choke valve is revolved to the left or to the right turn 90 degrees, at this moment the runner on that side core of flow path groove 1 and injecting products of vertical distribution communicates on the choke valve.
The utility model is installed on the dynamic mould core of mould, and three ripple pearl locating slots 3 of bottom cooperate with the location ripple pearl that is assemblied in equally on the dynamic mould core, and location ripple pearl plays positioning action when choke valve is rotated.
