Detailed Description

The following description is presented to disclose the utility model so as to enable any person skilled in the art to practice the utility model. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

Referring to fig. 1 to 6, an injection mold for processing an air conditioner case includes: movable mould, cover half 1, gating system, guide system, ejection system, exhaust system and cooling heating system, the movable mould comprises movable mould board 2 and movable mould chamber 3, still includes:

the eccentric sprue bush 4 is arranged at the top of the movable die and used for enabling the molten plastic material to enter a flow channel in the die;

the sleeve 5 is coaxially arranged with the eccentric sprue bush 4 and is sleeved on the periphery of the eccentric sprue bush 4;

a rotation system for rotating the sleeve 5 about its central axis;

and the guide system is used for providing guidance for the rotation process of the sleeve 5 so as to improve the rotation precision of the sleeve 5.

When the air conditioner shell is subjected to injection molding production, molten plastic liquid enters from the eccentric sprue bush 4 at the top of the movable mold, flows into the runner of the movable mold cavity 3 through the sleeve 5, flows into the fixed mold 1 and the movable mold cavity 3, and then rotates the sleeve 5 through the rotating system, so that a sprue in a molten state is cut off, and finally the molded air conditioner shell is short in sprue and easy to process, or the sprue is too short, so that the attractiveness and practicability are not influenced, and the treatment is not needed.

Further, a first pouring hole 6 is formed in the bottom of the eccentric sprue bush 4, and a central axis of the first pouring hole 6 is parallel to and does not coincide with a central axis of the eccentric sprue bush 4. The first pouring hole 6 at the bottom of the eccentric sprue bush 4 is eccentrically arranged, and the plastic liquid in a molten state flows into the sleeve 5 from the first pouring hole 6.

Further, a second pouring hole 7 is arranged at the bottom of the sleeve 5 and at a position corresponding to the first pouring hole 6, and the diameters of the first pouring hole 6 and the second pouring hole 7 are the same. In the process of moulding plastics, first sprue gate 6 and the coincidence of second sprue gate 7, molten plastics liquid can enter into the runner in the die cavity of cover half 1 through first sprue gate 6 and second sprue gate 7 smoothly, the liquid in movable mould and the die cavity of cover half 1 is full of the back, rotating system begins work, rotating system makes sleeve 5 take place the rotation to make second sprue gate 7 and first sprue gate 6 deviate completely, do not intersect, at this moment, the runner in movable mould cavity 3 is cut off by sleeve 5 with the runner in the eccentric runner cover 4.

Further, the rotation system includes:

the motor 8 is in a vertical state, an output shaft of the motor is vertically downward, and the motor 8 is fixedly arranged at the top of the movable die through the mounting block 9;

a first gear 10 fixedly arranged on an output shaft of the motor 8;

and a second gear 11 formed on the top of the sleeve 5, wherein the second gear 11 can be meshed with the first gear 10.

When the rotating system begins to work, the output shaft of the motor 8 drives the first gear 10 to rotate, and the first gear 10 and the second gear 11 can be meshed with each other, so that the second gear 11 is driven to rotate, namely the sleeve 5 rotates, and when the sleeve 5 rotates, the second pouring hole 7 and the first pouring hole 6 deviate, so that the pouring gate is cut off.

Further, a first accommodating groove 12 for accommodating the first gear 10 and a second accommodating groove 13 for accommodating the second gear 11 are formed in the bottom surface of the movable die plate 2.

First gear 10 and second gear 11 can design into the type with the number of teeth and different numbers of teeth according to actual demand, can design into the same with the number of teeth of first gear 10 and second gear 11, this moment, the rotational speed of first gear 10 is the same with the rotational speed of second gear 11, the number of teeth that is big when first gear 10 is greater than the number of teeth of second gear 11, then the rotational speed of second gear 11 is greater than the rotational speed of first gear 10, realize acceleration function promptly, the number of teeth that is less than second gear 11 when first gear 10, then the rotational speed of second gear 11 is less than the rotational speed of first gear 10, realize deceleration function promptly, first holding tank 12 and second holding tank 13 process according to the overall dimension of first gear 10 and second gear 11, ensure at the rotatory in-process of first gear 10 and second gear 11, do not produce the interference.

Further, the guidance system includes:

the number of the guide convex circles 14 is a plurality, the guide convex circles are in a vertical state, and the guide convex circles are circumferentially distributed on the top of the second gear 11;

the guide groove 15 is formed in the bottom of the movable template 2, and the guide convex circles 14 are inserted into the guide groove 15.

Because the first gear 10 is fixedly connected to the output shaft of the motor 8, and the motor 8 is fixed to the top of the movable mold through the mounting block 9, the rotation of the first gear 10 is very stable, but when the second gear 11 is driven by the first gear 10 to rotate, the second gear 11 is formed at the top of the sleeve 5, the sleeve 5 is sleeved on the periphery of the eccentric sprue bush 4, but a certain gap exists between the sleeve 5 and the eccentric sprue bush 4, so that the rotation of the second gear 11 is unstable, even the second gear is out of gear with the first gear 10, so that the guide convex circles 14 are arranged at the top of the second gear 11, when the second gear 11 rotates, the guide convex circles 14 make circular motion in the guide grooves 15, and each guide convex circle 14 and each guide groove 15 are processed according to the sliding fit precision.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the utility model, but that various changes and modifications may be made without departing from the spirit and scope of the utility model, which fall within the scope of the utility model as claimed.
