Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a mold structure for quick assembly and disassembly of inserts. Background Technology

[0002] In the mold manufacturing process, in order to control the quality of the product and related product information, it is necessary to engrave information on the mold cavity or core. The traditional method is to embed an engraving insert in the mold, which requires professional personnel to disassemble the mold for replacement, resulting in a long replacement cycle and seriously affecting normal production. Summary of the Invention

[0003] To address the aforementioned technical problem of long mold disassembly cycles, this utility model provides a mold structure for quick assembly and disassembly of inserts.

[0004] The technical solution of this utility model is as follows:

[0005] A mold structure for quick-assembly and disassembly of inserts includes an upper mold frame and an upper fixing plate. The inner wall of the upper mold frame is recessed, and an upper mold core is provided in the recessed area. The upper fixing plate is provided on the surface of the upper mold frame. The upper mold frame is penetrated in the middle, and a magnetic seat is provided in the penetration. The magnetic seat is fixedly installed at the bottom of the upper fixing plate. A ball screw is provided at the bottom of the magnetic seat. An engraved insert is provided on the inner wall of the upper mold core. The outer wall of the engraved insert is sloping, and the surface of the engraved insert has an mounting plane. A magnetic seat wrench is provided on the outer wall of the magnetic seat. The upper part of the magnetic seat wrench has a switch mark ON position and a switch mark OFF position. The magnetic force of the magnetic seat is controlled by turning the magnetic seat wrench to the ON position or the OFF position of the switch mark.

[0006] There are two ball screws, arranged vertically, and each ball screw has a built-in spring.

[0007] The top edge of the engraved inlay is recessed.

[0008] The upper mold core is located at the bottom center of the upper mold frame.

[0009] The upper mold core has a mounting groove in the middle, and a baffle is provided at the top of the mounting groove. The diameter of the baffle is smaller than the upper and lower diameters.

[0010] The technical solution of this utility model has a novel structure and a clever and simple design. The lettering insert can be quickly assembled and disassembled by a magnetic base and ball screws fixed in the upper mold frame. When the magnetic base wrench is turned to the ON position, the magnetic base generates magnetic force to firmly fix the lettering insert in contact, thus fixing the lettering insert; when the magnetic base wrench is turned to the OFF position, the magnetic force of the magnetic base disappears, and the lettering insert is pushed out by the force of the ball screw, thus disassembling the lettering insert.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0015] like Figure 1 , 2 The mold structure for quick assembly and disassembly of inserts shown in Figures 3 and 4 includes an upper mold frame 2 and an upper fixing plate 1. The inner wall of the upper mold frame 2 is recessed, and an upper mold core 4 is provided in the recessed area. The upper fixing plate 1 is provided on the surface of the upper mold frame 2. The upper mold frame 2 is penetrated in the middle, and a magnetic seat 3 is provided at the penetration point. The magnetic seat 3 is fixedly installed at the bottom of the upper fixing plate 1. A ball screw 5 is provided at the bottom of the magnetic seat 3. The inner wall of the upper mold core 4 is provided with an engraved insert 6. The outer wall of the engraved insert 6 is sloping, and the surface of the engraved insert 6 is provided with a mounting plane 8. The outer wall of the magnetic seat 3 is provided with a magnetic seat wrench 7. The upper part of the magnetic seat wrench 7 is provided with a switch mark ON position and a switch mark OFF position. The magnetic force of the magnetic seat 3 is controlled by turning the magnetic seat wrench 7 to the switch mark ON position or the switch mark OFF position.

[0016] There are two ball screws 5, which are set vertically and have built-in springs.

[0017] The top edge of the engraved inlay 6 is recessed.

[0018] The upper mold core 4 is located at the bottom center of the upper mold frame 2.

[0019] The upper mold core 4 has a mounting groove in the middle, and a baffle is provided at the top of the mounting groove. The diameter of the baffle is smaller than the upper and lower diameters.

[0020] In use, the working principle is as follows: In the adsorption state, when the magnet rotates to a specific position so that the N and S poles face the two magnetic conductors respectively, the magnetic field lines start from the N pole, pass through the magnetic conductor, then through the steel object in contact with the magnetic base, reach the other magnetic conductor, and finally return to the S pole, forming a closed magnetic field. At this time, the soft magnetic material base is magnetized, generating a strong magnetic force that allows it to firmly adhere to the surface of the steel object. In the separation state, when the magnet rotates 90 degrees so that the two poles are horizontal, i.e., the exact center of the N and S poles faces the soft magnetic material base, the magnetic field at the very center of the long bar magnet is negligible, and the soft magnetic material base is not magnetized. At this time, there is almost no magnetic force on the base, and it can be easily separated from the steel object. The magnetic base is a common component when the surface is removed. This switch-type mechanism works by changing the magnetic field. The mounting surface is a steel object. The lettering insert is quickly assembled and disassembled by the magnetic base and ball screws fixed in the upper mold frame. When the magnetic base wrench is turned to the ON position, the magnetic base generates magnetic force to firmly fix the lettering insert in contact, thus fixing the lettering insert. When the magnetic base wrench is turned to the OFF position, the magnetic force of the magnetic base disappears, and the lettering insert is pushed out by the outward force of the ball screw, thus removing the lettering insert. The ball screw has a built-in spring. When the lettering insert is installed, because the magnetic force of the magnetic base is greater than the outward force of the spring, the ball of the ball screw moves inward into the mounting surface. When the lettering insert is removed, the spring rebounds, causing the lettering insert to fall out of the mounting groove of the upper mold core.
