Description

Technical Field

[0001] The utility model relates to the technical field of slide inner elastic block moulds, in particular to a simple slide inner elastic block mould. Background Art

[0002] The slide mechanism of the mold generally refers to the slide mechanism of the mold, that is, any mechanism that can obtain lateral core pulling or lateral parting and reset action to pull out the product undercut, depression and other positions. The slide on the mold is a moving part that can drive it to move sideways (generally 90 degrees perpendicular to the mold opening direction) when the front and rear molds are opened horizontally. The purpose is to make it detach from the product buckle position so that the ejector (or gas) can smoothly eject the product.

[0003] The existing simple slide inner spring block mold, when installing the spring block mold, must first install the spring into the slide seat, then install the slide spring block and the slide insert, and finally screw in to fix it. However, after first installing the slide spring block inside the slide seat, the slide insert is fixed on the slide seat. Because the slide insert semi-surrounds the slide spring block and fixes it, once the slide insert lacks a positioning structure during installation, it will often conflict with the slide spring block, so it is easy to cause wear between the slide spring block and the slide insert, which ultimately affects the service life of the simple slide inner spring block mold.

The specific structural principle is omitted here. A slide insert installation positioning structure 10 is fixedly installed at the front end of the slide seat 3. The slide insert installation positioning structure 10 comprises a positioning rod 101, a sleeve 102 and a slot 104. The positioning rod 101 is fixedly installed on the front end outer wall of the slide seat 3. The outer side of the positioning rod 101 is slidably connected with the sleeve 102. The sleeve 102 can slide left and right on the positioning rod 101. A slide groove 103 is fixedly installed at the front end of the sleeve 102. A sliding plate 105 is slidably connected to the inner side of the slide groove 103. The slot 104 is fixedly opened on the positioning rod 101. The top end, the lower end of the sliding plate 105 is movably connected to the inner side of the card slot 104. When it is necessary to position the installation slide insert 2, the sliding plate 105 is first slid upward along the sliding slot 103, and the inner side of the leaked sleeve 102 is sleeved inside the positioning rod 101. At this time, the sleeve 102 will limit the horizontal height of the slide insert 2, and then the slide insert 2 is pushed into the slide seat 3 until the bottom end of the sliding plate 105 slides along the positioning rod 101 and encounters the card slot 104. At this time, the sliding plate 105 will slide down into the position of the card slot 104 inside the card slot 104 to clamp the sleeve 102, and the slide insert 2 can be fixed at the designated position at the front end of the slide seat 3. The lower end of the sleeve 102 is fixedly connected to the top of the slide insert 2, and the upper side of the slide insert 2 and the positioning rod 101 are arranged parallel to each other;

[0022] The sleeve 102 can slide left and right on the positioning rod 101. When it is necessary to position the installation of the slide insert 2, first slide the sliding plate 105 upward along the sliding groove 103, and then put the inner side of the leaked sleeve 102 into the positioning rod 101. At this time, the sleeve 102 will limit the horizontal height of the slide insert 2, and then push the slide insert 2 into the slide seat 3 until the bottom end of the sliding plate 105 slides along the positioning rod 101 and encounters the slot 104. At this time, the sliding plate 105 will slide down into the slot 104 and clamp the sleeve 102, so that the slide insert 2 can be fixed at the specified position at the front end of the slide seat 3. The structure that can position the installation of the slide insert 2 reduces the conflict and wear between the slide insert 2 and the slide spring block 7, thereby improving the service life of the simple slide inner spring block mold.
