Description

Technical Field

[0001] The utility model belongs to the technical field of mold fixing, in particular to a mold fixing device for a drawer gear precision part. Background Art

[0002] According to the authorized patent with application number CN216230901U, a fixing mechanism for molds is disclosed. The utility model uses a sponge pad, a scale, an anti-skid cover, an anti-vibration pad, and a scale to cooperate with each other for connection and use, so that the sponge pad can protect the mold surface to avoid scratches and damage on the mold surface. Then, the scale can accurately measure the length of the mold, thereby improving the overall accuracy of the device. The anti-vibration pad solves the overall friction of the device, and the anti-skid cover effectively protects the user to prevent long-term work from causing certain injuries to the hands. The problem that the device does not have a certain protective effect and poor accuracy is solved. However, the following problems still exist, such as:

[0003] When the fixing mechanism of the mold is working, it is necessary to wait until the hydraulic rod is fully retracted. Because the pressed object is in contact with the mold for a long time, it is too difficult to demold the pressed object from the mold during the demolding process, and there may be a situation where the pressed object cannot be removed. This device pulls the connecting rod upward at the same time when the hydraulic rod rises, and pulls the connecting rod and the push plate to the left, so that the demolding ring moves upward and then lifts the pressed object for rapid demolding. For this purpose, we provide a mold fixing device for precision parts of drawer gears. Utility Model Content

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a mold fixing device for a precision gear part of a drawer, comprising a demoulding mechanism and a top plate, wherein a fixing mechanism is arranged at the bottom of the top plate, a movable groove is arranged inside the top plate, a slide groove is arranged inside the movable groove, a slide rod is slidably connected to the inner wall of the slide groove, a clamping block is fixedly connected to the top of the slide rod, a clamping plate is rotatably connected inside the clamping block, a spring 2 is fixedly connected to the outer side of the clamping plate, and a connecting rod is rotatably connected inside the slide rod;

The elastic force generated by the extrusion of the spring 3 pushes the mold inward, so that it is always in an extruded state and remains motionless, thereby preventing the mold from shifting during pressing.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model sets a demoulding ring, and the clamping block drives the sliding rod and the connecting rod to move upward. When the connecting rod moves upward, the connecting rod will be pulled to the left, and the push plate will move to the left through the movement of the connecting rod to the left. At the same time, when the push plate moves to the left, the movable block will be pushed up, and the push rod will be driven upward by the movable block, and then the demoulding ring will be driven upward by the movement of the push rod, and then the pressed object will be pushed up for rapid demoulding, so as to prevent the pressed object from sticking to the mold due to untimely demoulding, making it too difficult to remove, and it may be necessary to destroy the mold before it can be removed.

[0014] 2. The utility model provides a push plate 1. When the bevel gear 1 rotates, it drives the bevel gears 2 on the front and back sides to rotate. At the same time, the rotation of the bevel gear 2 drives the threaded rod to rotate, so that the push plate 1 moves inward. The push plate 1 moves inward to make the extrusion block contact with the outer side of the mold and squeeze the spring 3. The elastic force generated by the extrusion of the spring 3 pushes the mold inward, so that it is always in an extruded state and remains motionless, thereby preventing the mold from shifting during pressing.
