Abstract
The utility model discloses an outlet of thermal flow path moulds with adjustable cylinders, which comprises a cylinder body, a valve and a valve needle. A first threaded connector is connected with the valve by bolt joint to determine the fluctuating location of the valve needle. The upper end of the valve needle is connected with the first threaded connector. According to the technical solution of the present utility model, the downward extended length of the valve needle is changeable and is kept from being too long or too short due to large deviation of the total thickness of templates, thereby avoiding the damage of mould cores caused by valve needles or the failure of adhesive sealing.
Description
Technical field
The utility model relates to hot runner mould discharging mouth technical field, especially relates to a kind of hot runner mould discharging mouth with adjustable cylinder.
Background technology
In the prior art, hot runner mould discharging mouth is provided with cylinder and needle, is provided with piston in the cylinder, and the bottom of piston is fixed in the upper end of needle, drives needle during piston up-down and moves up and down.But, the bigger problem of template total thickness deviation can appear in the dress mould, the hot mouth of needle valve for hot flow path, the length that the appearance of this kind situation is stretched out needle downwards is long or too short, the length that needle stretches out downwards is long can damage die, and the length that needle stretches out downwards is too short then can't sealing.Therefore be necessary to be improved.
The utility model content
Deficiency at the prior art existence, the purpose of this utility model provides a kind of hot runner mould discharging mouth with adjustable cylinder, it can change the length that needle stretches out downwards, thoroughly solves the long or too short problem of length that the excessive needle that causes of template total thickness deviation stretches out downwards.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of hot runner mould discharging mouth with adjustable cylinder comprises the cylinder main body, piston and the needle that are arranged in the template, and piston is bolted with first threaded connector of the upper-lower position that is used to change needle, and the upper end of needle is connected in first threaded connector.
The screwed hole that connects piston is offered at described piston middle part, and first threaded connector is bolted in the screwed hole.
Described screwed hole is provided with seal, and seal is arranged at the upper end of first threaded connector.
The middle part of described screwed hole is provided with level and smooth internal face, and seal is a cylindrical shape, and the outer circumference surface of seal is provided with ring-shaped groove, is provided with sealing ring in the ring-shaped groove, the level and smooth internal face at the outer circumference surface of sealing ring closed Sealing and screwed hole middle part.
Described screwed hole is bolted with second threaded connector, and second threaded connector is arranged at the upper end of seal.
After adopting said structure, the utility model is compared the advantage that is had with prior art: the utility model can change the length that needle stretches out downwards, thoroughly solve the long or too short problem of length that the excessive needle that causes of template total thickness deviation stretches out downwards, avoid needle to damage die or can not sealing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, cylinder main body 2, piston 3, needle 4, first threaded connector 5, screwed hole 6, seal 7, sealing ring 8, second threaded connector.
The specific embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, see shown in Figure 1: a kind of hot runner mould discharging mouth with adjustable cylinder, comprise the cylinder main body 1, piston 2 and the needle 3 that are arranged in the template, piston 2 is arranged in the inner chamber of cylinder main body 1, piston 2 is bolted with first threaded connector 4 of the upper-lower position that is used to change needle 3, and the upper end of needle 3 is connected in first threaded connector 4.
The utility model can change the length that needle 3 stretches out downwards, thoroughly solves the long or too short problem of length that the excessive needle that causes 3 of template total thickness deviation stretches out downwards, avoids needle 3 to damage dies or can not sealing.
Piston 2 middle parts are offered screwed hole 5, the first threaded connectors 4 that connect piston 2 and are bolted in the screwed hole 5.Screwed hole 5 is provided with seal 6, and seal 6 is arranged at the upper end of first threaded connector 4.
Rotate first threaded connector 4, adjust the upper-lower position of first threaded connector 4 in screwed hole 5, thereby change the upper-lower position of needle 3, finally reach the purpose of the upper-lower position of regulating needle 3, adjusting to needle 3 is simple to operation, and can solve the long or too short problem of needle 3.
The middle part of screwed hole 5 is provided with level and smooth internal face, seal 6 is a cylindrical shape, the outer circumference surface of seal 6 is provided with ring-shaped groove, be provided with sealing ring 7 in the ring-shaped groove, the level and smooth internal face at the outer circumference surface of sealing ring 7 closed Sealings 6 and screwed hole 5 middle parts, seal 6 and sealing ring 7 from the middle part of piston 2 with screwed hole 5 sealings of piston 2.
Screwed hole 5 is bolted with the upper end that second threaded connector, 8, the second threaded connectors 8 are arranged at seal 6.Rotate second threaded connector 8, adjust the upper-lower position of second threaded connector 8 in screwed hole 5, also can regulate the upper-lower position of needle 3.And, second threaded connector 8 and first threaded connector 4 all screw tight in screwed hole 5, second threaded connector 8 and first screw thread are connected be securely fixed in the screwed hole 5, in use second threaded connector 8 and first screw thread connect and phenomenon loosening or displacement can not occur.
Cylinder main body 1, piston 2 and needle 3 are widely-used at present, and other structure and principle are same as the prior art, repeat no more here.
