Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-4, the present embodiment provides an injection molding apparatus for producing an instrument housing with a protective structure, which includes a base 1, a baffle 11 is disposed at the top of the base 1 around the outside of a groove, the baffle 11 is movably connected inside the base 1, the baffle 11 is disposed at the base 1 around the outside of the groove, a rod 23 is driven to move up and down by the movement of a cylinder 12, and a rod 13 is driven to move up and down by the movement of the cylinder 12, the operation and management of the cylinder 12 are known to those skilled in the art, and the cylinder 12 is a cylindrical metal component for guiding a piston to perform linear reciprocating motion inside the cylinder, and it is more convenient for the piston rod of the cylinder 12 to drive the rod 13 to move up and down, so that an injection molding plate 2 extends into the groove of the base 1 for injection molding, the baffle 11 is disposed at the outside of the groove at the base 1, and the baffle 11 extends up and down inside the base 1 to shield the groove, and there is no protective structure around, which may be scalded by splashed liquid during the injection molding process.

The utility model discloses when specifically using: at first through at base 1 around the outside baffle 11 that sets up of recess, stretch out and draw back from top to bottom in base 1 is inside through baffle 11, shelter from the recess, make roof 13 up-and-down motion drive stock 23 up-and-down motion simultaneously through cylinder 12 motion, make injection molding plate 2 stretch into and mould plastics in base 1's the recess, prevent when the mould is made, when needing operating personnel manual operation, because there is not protection architecture on every side, probably scald by the liquid of spill at the in-process of moulding plastics.

Consider that instrument case may block on injection molding board 2 in drawing of patterns process, and if operating personnel's manual drawing of patterns probably leads to the scald, influence drawing of patterns efficiency, consequently, at 23 inside springs 21 that are provided with of stock bottom recess, injection molding board 2 is connected to the spring 21 other end, through stock 23 up-and-down motion, drives the spring 21 motion, makes spring 21 promote injection molding board 2 and makes instrument case drop, avoids needing operating personnel's manual drawing of patterns to lead to the scald.

In order to facilitate the up-and-down movement of the long rod 23, a handle 24 is connected to the top of the long rod 23, and the long rod 23 is driven to move up and down by grasping the handle 24, so that the instrument shell is demoulded.

Considering that the instrument shell is closely connected with the injection molding plate 2 due to overhigh temperature, the instrument shell is damaged or is inconvenient to fall off during demolding, therefore, two L-shaped rods 27 are movably connected in the sliding grooves in the outer walls of the two sides of the long rod 23, the two L-shaped rods 27 are connected with the inner wall close to the bottom, the two L-shaped rods 27 slide on the outer wall of the long rod 23 to be aligned to the position of the injection molding plate 2, the injection molding plate 2 is cooled through the fans 28, the work management of the fans 28 is as known by the technical field, the fans are devices for generating air flow through electric drive, the fans arranged in the fans rotate after being electrified, mechanical energy is converted into wind energy, natural wind is formed to achieve a cooling effect, and demolding caused by overhigh temperature after the injection molding is inconvenient.

For the convenience of moving the injection molding plate 2 left and right, therefore, the upper plate 22 is placed at the upper end of the injection molding plate 2, the middle of the upper plate 22 is communicated with the long rod 23, four sliding rods 25 are respectively connected to four corners of the upper plate 22, the tops of the four sliding rods 25 are connected with four idler wheels 26, the four idler wheels 26 are movably connected in two sliding grooves in the bottom of the top plate 13, and the four idler wheels 26 slide in two sliding grooves in the bottom of the top plate 13 to drive the injection molding plate 2 to move left and right.

In order to avoid instrument case to drop near base 1's recess once more when droing, consequently, be connected with rectangular 14 near rear side department on base 1 top, rectangular 14 middle part swing joint has apron 15, and apron 15 rotates on rectangular 14 through the pivot, makes apron 15 can cover base 1's recess, drops into the recess when preventing the drawing of patterns and carries out the secondary and mould plastics.

The utility model discloses instrument shell production is with moulding plastics device when specifically using with protective structure, at first rotate on rectangular 14 through the pivot on the apron 15, open the inside recess of base 1, upwards stretch through baffle 11, prevent that the liquid that splashes when moulding plastics later scalds operating personnel, slide in two spouts of roof pole 13 bottom through four gyro wheels 26, it controls to drive about injection moulding board 2, make injection moulding board 2 remove to the base 1 recess directly over, make roof 13 up-and-down motion drive stock 23 up-and-down motion simultaneously through the motion of cylinder 12, make injection moulding board 2 stretch into and mould plastics in base 1's the recess, it accomplishes the back to mould plastics, stretch into stock 23 through handle 24, cool off the instrument shell through fan 28, make things convenient for the drawing of patterns, baffle 11 shrink downwards, apron 15 rotates once more on rectangular 14 through the pivot and covers the recess on base 1, drive the drawing of patterns board 2 through spring 21 up-and down motion, make things convenient for instrument shell.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
