Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A positioning structure for a mold comprises a movable mold 8 and a fixed mold 9, wherein a positioning groove 81 is formed in the movable mold 8, a positioning lug 91 is arranged at a corresponding position of the fixed mold 9, a positioning piece 1 and a locking mechanism 2 are further included, and the positioning piece 1 is arranged on the side wall of the positioning groove 81 and the side wall of the positioning lug 91 by using the locking mechanism 2. Can avoid like this that the contact surface takes place wearing and tearing between positioning groove 81 and the location lug 91, through the installation of spacer 1, only need replace spacer 1 can, reduced mould cost of maintenance. Generally, the positioning plate 1 is directly fixed on the side walls of the positioning groove 81 and the positioning projection 91 by screws.

In the above embodiment, there is a certain defect in the screw fixation, for example, the screw needs to rotate for several weeks when being locked to the positioning plate 1; especially, when the positioning plate 1 is installed in the positioning groove 81, the screwdriver cannot be even horizontally placed, and thus it is very inconvenient to rotate the screw. Therefore, in an embodiment, as shown in fig. 1 to 10, the locking mechanism 2 includes a locking block 21, a spring 22, a locking rod 23 and a fixing mechanism 24, two ends of the locking rod 23 are respectively provided with a first locking portion 231 and a second locking portion 232, the spring 22 is sleeved on the locking rod 23, the locking block 21 is concavely provided with an accommodating cavity 211 for accommodating the spring 22, the bottom of the accommodating cavity 211 is provided with a first through hole 212, the corresponding positions of the movable mold 8 and the fixed mold 9 are provided with a second through hole 3, the fixing mechanism 24 is fixedly arranged in the second through hole 3, one end of the locking rod 23 provided with the first locking portion 231 penetrates through the first through hole 212 and is inserted into the second through hole 3 to be connected with the fixing mechanism 24 through the first locking portion 231, and the second locking portion 232 is elastically connected with the bottom of the accommodating cavity 211 through the spring. That is, both ends of the spring 22 are connected to the second locking part 232 and the bottom of the accommodation chamber 211, respectively.

As shown in fig. 1-10, among other things, securing mechanism 24 includes a body 241 and a locking slot 242 disposed at an end of body 241. The first locking portion 231 is a lock piece extending laterally, and the first locking portion 231 is rotated into the locking groove 242 by the rotation of the locking lever 23. Specifically, when the positioning protrusion 91 is mounted, the second through hole 3 is horizontally formed in the positioning protrusion 91, the locking grooves 242 are formed at both ends of the body 241, the side wall of the locking rod 24 is provided with a locking hole, a through hole corresponding to the locking hole is formed in the corresponding position of the positioning protrusion 91, the locking pin is inserted into the locking hole through the through hole, the fixing mechanism 24 is connected with the positioning protrusion 91 through the locking pin, and the mode fixing mechanism 24 rotates. In addition, for the installation of the fixing mechanism 24 of the positioning groove 81, the method is the same as the installation of the positioning projection 91, except that the locking groove 242 is only required to be provided at one end of the body 241. Preferably, the locking groove 242 has a thickness greater than that of the first locking part 231; to facilitate entry of the first locking portion 231 into the locking groove 242.

In one embodiment, as shown in fig. 1 to 10, in order to prevent the locking rod 23 from rotating during use, a limiting groove 213 is disposed at the opening of the accommodating cavity 211, and a limiting block 233 is disposed at a side edge of the second locking portion 232; that is, a rotation space 214 allowing the stopper 233 to rotate is formed between the stopper groove 231 and the accommodation chamber 211. When the first locking portion 231 is locked with the fixing mechanism 24, the limiting block is disposed in the limiting groove. During the use, promote locking lever 23 along its axial displacement for spring 22 compresses, stopper 233 gets into rotatory space 214 in, rotatory locking lever 23 for first locking portion 231 is connected with fixed establishment 24, and simultaneously, stopper 233 gets into spacing groove 213, utilizes the elasticity of spring 22, makes spacer 1 closely laminate with positioning groove 81 and locating lug 91.

As shown in fig. 8, to facilitate the mounting of the locking lever 23 to the securing mechanism 24, the surface of the second locking portion 232 is provided with a hexagonal socket. The rotation of the locking lever 23 can be achieved by a socket head wrench.

In one embodiment, as shown in FIGS. 1-12, the spacer 1 is recessed with a groove 11 that mates with a locking block 21. Preferably, when the locking block 21 is disposed in the groove 11, the surface of the locking block 21 is lower than the surface of the groove 11. Thereby not affecting the normal use of the locating plate 1.

In one embodiment, as shown in fig. 1-12, at least one positioning salient point 12 is convexly arranged on the positioning plate 1, and positioning concave points matched with the positioning salient points 11 are arranged on corresponding positions on the movable die 8 and the fixed die 9. Generally, four positioning convex points 12 are arranged in a rectangular arrangement, and correspondingly, four positioning concave points are also arranged; when the positioning sheet 1 is installed, the positioning convex points 12 are installed in the positioning concave points to realize the positioning of the positioning sheet 1; then the locating plate is fixed through the locking mechanism 2.

In one embodiment, as shown in fig. 1-12, the edge of the positioning block 1 is chamfered. So that the positioning bump 91 can enter the positioning groove 81 conveniently, and the positioning of the mold can be realized.

When the utility model is used, as shown in fig. 1-12, taking the installation of the positioning plate 1 on the positioning bump 91 as an example, firstly, the positioning salient point 12 of the positioning plate 1 is inserted into the positioning concave point, so as to determine the installation position of the positioning plate 1, and then the locking mechanism 2 is installed; firstly, the locking block 21 is installed in the groove 11, the locking rod 23 is pushed to move axially, the spring 22 is compressed, the locking rod 23 is rotated, the first locking part 231 enters the locking groove 242, meanwhile, the limiting block 233 enters the limiting groove 213, the limiting rod 23 can only move axially and cannot rotate, and therefore the first locking part 231 and the fixing mechanism 24 are always in a locking state when in use; when the positioning piece is disassembled, only the locking rod 23 needs to be pushed to move axially, when the limiting block 233 enters the rotating space 214, the locking rod 23 is rotated to enable the first locking part 231 to leave the locking groove 242, and then the locking mechanism 2 is taken out.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
