DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 , the utility model provides two technical solutions:

[0021] Embodiment 1

[0022] A tooling fixture for producing mold parts to prevent misprocessing, comprising a base 1, a non-slip pad 101 is fixedly connected to the middle position of the bottom end of the base 1, a workbench 2 is rotatably connected to the middle position of the top end of the base 1, a positioning device 3 is arranged inside one side of the workbench 2, a first clamping mechanism 4 is arranged at the bottom end of the inside of the workbench 2, a second clamping mechanism 5 is arranged at the top end of the inside of the workbench 2, clamping blocks 6 are arranged on both sides of the top end of the second clamping mechanism 5, and a sensing mechanism 7 is arranged on one side of the inside of the clamping block 6. The first clamping mechanism 4 and the second clamping mechanism 5 have the same internal specifications, and are both provided with accessories such as a servo motor 501, a bidirectional threaded rod 502, a threaded block 503, and a clamping block 6. By starting the first clamping mechanism 4, the front and rear groups of clamping blocks 6 at the top end of the workbench 2 can be driven to move relative to each other.

[0023] The second clamping mechanism 5 includes a servo motor 501 installed on one side of the workbench 2, and a bidirectional threaded rod 502 is installed on the output shaft end of the servo motor 501. The two sides of the outside of the bidirectional threaded rod 502 are threadedly connected with a threaded block 503 whose top is fixedly connected to the clamping block 6. When the servo motor 501 is started, it can drive the bidirectional threaded rod 502 to rotate. At this time, the bidirectional threaded rod 502 can drive the clamping block 6 to move relative to the top of the workbench 2 through the threaded block 503.

[0024] The sensing mechanism 7 includes a pressure sensor 701 installed on one side of the clamping block 6. There are four groups of pressure sensors 701 installed inside the four groups of clamping blocks 6. Each sensor can detect the pressure change at a specific position or component. At the same time, each sensor transmits the detected pressure signal to the central control system through a signal line. After the central control system receives the signals from the four groups of sensors, it performs logical judgment. When the four groups of pressure sensors all receive the pressure signals and generate a start signal, the mold parts can be processed.

[0025] A rubber head 8 is slidably connected to the middle position of one side of the clamping block 6, a square block 801 is fixedly connected to one side of the rubber head 8, a push block 802 is fixedly connected to the middle position of one side of the square block 801, and a second spring 803 is fixedly connected to one side of the square block 801. The rubber head 8 is made of rubber material, which can reduce the friction generated by contact with mold parts. At the same time, the rubber head 8 can be subjected to force by squeezing the second spring 803 through the square block 801, and the square block 801 can push the push block 802 to move.

[0026] Embodiment 2

[0027] The main difference from the first embodiment is:

[0028] A tooling fixture for mold part production that prevents misprocessing, wherein the positioning device 3 includes positioning grooves 102 evenly arranged at equal distances on the top of the base 1, a pulling block 301 slidably connected to the outer side of the workbench 2, a movable block 302 is fixedly connected to one side of the pulling block 301, a first spring 303 is fixedly connected to the top of the movable block 302, and a positioning rod 304 that is engaged with the positioning groove 102 is fixedly connected to the middle position of the bottom of the movable block 302. When the pulling block 301 is pulled, the pulling block 301 can squeeze the first spring 303 through the movable block 302, and the movable block 302 can drive the positioning rod 304 below to lift. When the pulling block 301 is released, the positioning rod 304 can be reset by driving the movable block 302 due to the reaction force of the first spring 303 being squeezed. At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] When the embodiment of the present application is in use: the mold part to be processed is placed in the middle position of the top of the workbench 2. At this time, the first clamping mechanism 4 and the second clamping mechanism 5 inside the workbench 2 are started to drive the clamping block 6 to move on the top of the workbench 2. At this time, the clamping block 6 can clamp the mold part. At the same time, a rubber head 8 is installed on one side of the clamping block 6. When the rubber head 8 contacts the mold part, the second spring 803 can be squeezed through the square block 801. At this time, the square block 801 can push the push block 802 to move. When the four groups of push blocks 802 are in contact with the clamping block 802, the second spring 803 can be squeezed through the square block 801. At this time, the square block 801 can push the push block 802 to move. When the holding block 6 touches the internal pressure sensor 701, the central control system can control the processing assembly to process the mold parts on the top of the workbench 2 after receiving the signals from the four groups of sensors. At the same time, the pulling block 301 on the workbench 2 is pulled, and the pulling block 301 can drive the positioning rod 304 to be pulled out of the positioning groove 102 on the base 1 through the movable block 302. At this time, the mold parts can be driven to rotate through the workbench 2, and the positioning rod 304 can be inserted into the positioning grooves 102 at different positions on the base 1, so that the position of the mold parts after rotation can be fixed.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
