Description

Mold clamp for injection molding machine
Technical Field
The invention relates to the technical field of molds, in particular to a mold clamp for an injection molding machine.
Background
An injection molding machine is also known as an injection molding machine or an injection machine. It is a main forming equipment for making various shaped plastic products from thermoplastic plastics or thermosetting plastics by using plastic forming mould. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. The mould of injection molding machine need be fixed it with anchor clamps, and current mould for injection molding machine anchor clamps structure is comparatively single, generally fixes the mould through the hydraulic pump, and this kind of fixed mode is comparatively inconvenient when the operation, and the hydraulic pump uses the back for a long time and often takes place phenomenons such as oil leak starvation, has brought the inconvenience for relevant work.
In addition, although the clamping arm is convenient to move by using the motor, the clamping force is difficult to control after the clamping, a complex control system and a feedback system are needed to control the rotation and the stop of the motor, the cost is relatively high, and the structure is complex.
The traditional mode that the clamping arm is pushed to clamp by using threaded connection is relatively simple, but the distance for moving the clamping arm by rotating the thread for one circle is small, and the other clamping arm needs to be matched and moved to clamp a die quickly, so that the operation is relatively troublesome.
Therefore, a mold clamp for an injection molding machine, which has a simple structure, is convenient to use and has low cost, is needed.

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1 and 2, the mold clamp for the injection molding machine comprises a base 1, a clamping table 2 is fixed on the upper side of the base 1, a guide plate 3 and a fixing plate 5 are fixed on the upper side of the clamping table 2, a rack 4 is embedded into the guide plate 3, the left end of the rack 4 is a smooth outer wall, and the guide plate 3 is movably connected with the left end of the rack 4. The right end of the rack 4 is connected with a movable clamping arm 9, a slide rail 11 is fixed on the clamping table 2, and a slide block 12 is connected between the slide rail 11 and the movable clamping arm 9. The upper side of the rack 4 is provided with a first gear 6 and a second gear 7, the second gear 7 is meshed with the rack 4, the lower side of the rack 4 is provided with a third gear 8, and the third gear 8 is meshed with the rack 4. The first gear 6, the second gear 7 and the third gear 8 are all fixed on the fixed plate 5. Hand cranks 22 are fixed on the side surfaces of the first gear 6 and the second gear 7, so that the gears can be rotated manually. The right side of the movable clamping arm 9 is provided with a fixed clamping arm 10, and the fixed clamping arm 10 is fixed on the upper side of the clamping table 2. The first gear 6 is meshed with the second gear 7, and the number of teeth of the first gear 6 is smaller than that of the second gear 7. When the first gear 6 or the second gear 7 is rotated, the three gears rotate simultaneously, and the rack 4 drives the movable clamping arm 9 to move. Can hold hand crank 22 on the second gear 7 when removing movable arm lock 9, rotate second gear 7, can be fast be close to the mould with movable arm lock 9, because the number of teeth of first gear 6 is less than the number of teeth of second gear 7, can trade when movable arm lock 9 and mould butt with first gear 6 as the action wheel, hold hand crank 22 on the first gear 6 and rotate, lever principle, first gear 6 can be more laborsaving when rotating, and can provide great thrust, push the mould to the right side and fixed arm lock 10 butt, but the rotation opposite direction of first gear 6 and second gear 7.
As shown in fig. 2, 3, 4 and 5, the fixing plate 5 is further fixed with a fixing block 15, and a circular hole 21 is formed inside the fixing block 15. The inside embedding of round hole 21 has the activity to tie 16, and the right-hand member of activity tie 16 is fixed with screens pinion rack 13, and screens pinion rack 13 can mesh with third gear 8, is connected with spring 14 between screens pinion rack 13 and the fixed block 15, specifically, is two springs 14, and two springs 14 are located the both sides of activity tie 16 respectively. The elastic force of the spring 14 pushes the blocking toothed plate 13 to the right side, so as to be meshed with the third gear 8, and at the moment, the third gear 8 and the rack 4 are locked, so that the clamping arm is suitable for being in a clamping state. As shown in fig. 5, a collar may be fixed to the right side of the fixing block 15, so that the radial force of the movable bolt 16 is balanced better, and the toothed plate 13 is prevented from shaking when being stressed in the vertical direction.
