Description

Can regulate cast gate and mill into mechanism

Technical field

The utility model belongs to the Casting Equipment field, especially a kind ofly regulates cast gate and mills into mechanism.

Background technology

In foundry production, after making sand mold, need on sand mold, make a cast gate, so that molten iron can inject in the die cavity of sand mold by cast gate.Usually need use gate stick when making cast gate, promptly installing hole is made in the several fixed positions on the main frame of foundry production line, and gate stick is installed in one of them installing hole, when filling moulding cast gate is once made.This kind structure cast gate is made fast, but this structure also exists shortcoming: 1. because the installing hole on the main frame is fixing and limited, therefore gate stick can not arbitrarily be adjusted according to the position of die cavity, increased the limitation that machine uses, be not suitable for size, variform model are carried out the making of cast gate; 2. it is cumbersome to change gate stick, wastes time and energy, and has reduced production efficiency; 3. gate stick all carries out work above sandbox, when it leaves sandbox, stays loose sand easily in die cavity, causes cast(ing) surface or inside sand holes to occur, influences the quality of foundry goods, causes percent defective to rise.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, simple to operate, can adjust gate location at any time and can guarantee effectively that the cast gate regulated of casting quality mills into mechanism.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of cast gate of regulating mills into mechanism, constitute by motor, oil cylinder, frame, operation has sandbox on frame, it is characterized in that: all be fixed with a longitudinal rail in the same way in the central rack both sides, operation has a crossbeam track on this longitudinal rail, one travelling car is installed on this cross slide way, vertically be fixed with an oil cylinder on this travelling car, in this oil cylinder upper end one milling cutter is installed, this oil cylinder bottom installs one can drive the motor that milling cutter rotates, and in crossbeam track one side the vertical, horizontal moving handle is installed.

And the roller that described crossbeam track is installed by its two ends is slidingly mounted on the longitudinal rail.

And, also be fixed with a support on the described travelling car, on this support, a cleaning device that is made of cylinder and nozzle is installed with the milling cutter opposite position.

And described horizontal moving handle links together by a pull bar and travelling car.

Advantage of the present utility model and beneficial effect are:

1. the travelling car in this device can be done transverse movement on the crossbeam track, the crossbeam track can be done on longitudinal rail again and vertically move, by the vertical, horizontal motion of crossbeam track and travelling car, can be according to the gate location of foundry goods, the position of random adjustment milling cutter; And laterally be shaped on the moving handle and also be fixed with vertical rule on scale, the frame, can effectively guarantee the accuracy that milling cutter moves.

2. control gate location by the position of adjusting milling cutter, can save the trouble of changing gate stick in the conventional cast method, not only time saving and energy saving, and improved operating efficiency.

3. milling cutter is positioned at the bottom of sandbox, and this makes the mode of cast gate from the bottom up, can effectively avoid leaving over loose sand in the running channel, prevents that the sand holes phenomenon from appearring in foundry goods, has well guaranteed the quality of foundry goods, has reduced the percent defective of foundry goods.

4. of the present utility model simple in structure, reasonable in design, the adjustment of milling cutter position is flexible and precision is high, can make cast gate in any position of sandbox according to shape, the size of foundry goods, and the production efficiency height, and casting quality is good.

The specific embodiment

The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

The upper end that is fixed on two frames 9 on the basis is fixed with two delivery tracks, can move sandbox 3 by roller 8 on these two delivery tracks.Be fixed with at the middle part of these two frames two with frame longitudinal rail 10 in the same way, these two guide rails have a crossbeam 13 by roller 12 operations, this crossbeam is provided with crossbeam track 7, by roller 14 operations one travelling car 5 is arranged on this crossbeam track.Be fixed with an oil cylinder 15 on this travelling car, the upper end of this oil cylinder is equipped with a milling cutter 4; The bottom of this oil cylinder is connected with a motor 16, and this motor can drive milling cutter and rotate, and this milling cutter is realized rising and rotation by the driving of oil cylinder and motor.

Be equipped with in crossbeam one side and vertically move handle 17 and horizontal moving handle 11, vertically move handle and can control the vertically operation on longitudinal rail of travelling car, laterally moving handle links together by pull bar 6 and travelling car, can drive travelling car moves laterally on the crossbeam track, be shaped on scale on this horizontal moving handle, also be fixed with vertical rule (not shown) on the frame, this vertical, horizontal scale can accurately be controlled the displacement of travelling car, thereby accurately adjusts the position of milling cutter.Vertically moving handle and laterally moving handle is other also has two set levers (among the figure not label), these two set levers are installed on the crossbeam track.Set lever can avoid vertically moving handle or the horizontal moving handle phenomenon that causes the milling cutter position to change because of accident moves.

In order to guarantee the even running of travelling car on longitudinal rail, also be separately installed with the directive wheel 18 of longitudinal rail in the both sides of moving handle.

In order better the loose sand in die cavity and the running channel to be cleaned out, on travelling car, also be fixed with a support 1, on this support, a cleaning device is installed with the milling cutter opposite position, this cleaning device is made of cylinder and nozzle 2, gases at high pressure by cylinder can blow the loose sand that is retained in die cavity and the running channel off, to guarantee the quality of foundry goods.

In the utility model, motor can drive the milling cutter rotation, and the bottom of the sandbox that can move above it mills out cast gate.Compare with the method for making cast gate on sandbox top in the past, make cast gate in the sandbox bottom and can effectively prevent to leave in the running channel loose sand, reduce the probability that sand holes appear in foundry goods greatly.

Operation principle of the present utility model is:

According to the position of cast gate on sandbox, operation vertical, horizontal moving handle is adjusted milling cutter to the precalculated position, with set lever locking, makes the milling cutter fixed-site.When entering along delivery track, mills when watering mouth mechanism by sandbox, the rotation of driven by motor milling cutter, and oil cylinder promotes milling cutter and rises simultaneously, and the position that the milling cutter of rotation is stipulated below sandbox mills out cast gate, and oil cylinder descends then, and motor quits work, the cast gate completion of processing; Cylinder operation in the cleaning device blows the loose sand that is retained in die cavity and the running channel off simultaneously.
