Description

Technical Field

[0001] The utility model relates to the field of production molds, in particular to a quick-detachable three-time ejection mold structure. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. The mold has a specific contour or inner cavity shape. The use of a contour shape with a cutting edge can make the blank separate (punch) according to the shape of the contour line. The use of the inner cavity shape can make the blank obtain the corresponding three-dimensional shape. The mold generally consists of two parts: a movable mold and a fixed mold (or a punch and a die), which can be separated or combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming; at the same time, the mold can be divided into different types according to the different objects to be processed and produced.

[0003] Terminal mold is a mold tool used to make wire connection terminals. It is usually made of high-hardness alloy steel or carbon steel. The surface is passivated and can resist high temperature, wear and corrosion. The terminal mold can be used to make the connection terminals into different shapes and sizes to meet different circuit connection needs.

[0004] In traditional technology, terminal molds are usually produced with an integral mold base and mold core, but terminal molds are more unstable than pure plastic molds, and the probability of repair is higher. It is time-consuming and labor-intensive to repair the entire mold base, and it takes up more space to store; a special area is required to place the mold. Using a dedicated mold base for each case means that it costs more and the cost recovery period is longer. Utility Model Content

[0005] The utility model aims to solve the above defects and provide a quick-detachable three-time ejection mold structure.

[0006] The purpose of the utility model is achieved in the following manner: a quick-detachable three-time ejection mold structure comprises a male mold plate, a small mold frame pad, a first small mold frame ejector plate, a second small mold frame ejector plate, a small mold frame ejector pad, a small mold frame spring plate, a large mold frame ejector plate and a large mold frame ejector pad are sequentially arranged below the male mold plate from top to bottom, a fixing plate is arranged on the outer side of the male mold plate, a mounting position matching the male mold plate is arranged in the middle of the fixing plate, a mold frame ejector rod is arranged in the middle of the large mold frame ejector pad, the mold frame ejector rod extends toward the bottom surface of the first small mold frame ejector plate, ejector blocks are arranged at both ends of the small mold frame spring plate, the ejector block is connected to the large mold frame ejector plate, a limiting column is arranged above the ejector block, a large mold frame pad is arranged on the top of the limiting column, ejector rods are arranged around the bottom surface of the large mold frame ejector pad, the ejector rods extend toward the top surface of the male mold plate, and a reset spring is arranged between the small mold frame pad and the first small mold frame ejector plate.

[0007] In the above description, a further solution is provided in which a guide column is provided in the middle of the return spring, the guide column is arranged on the bottom surface of the ejector plate of the second small mold frame, and one end of the guide column away from the ejector plate of the second small mold frame extends toward the top surface of the male mold plate.

[0008] In the above description, a further solution is provided in which a support column is provided on the bottom surface of the ejector plate of the small mold frame, and one end of the support column away from the ejector plate of the small mold frame extends toward the bottom surface of the small mold frame plate and the support column conflicts with the bottom surface of the small mold frame plate.

[0009] In the above description, a further solution is provided, in which a movable position matching the ejector plate of the first small mold frame is provided in the middle of the large mold frame pad, and an avoidance through hole matching the ejector rod is provided near the ejector rod of the large mold frame template, and a limit column is fixed on the bottom surface of the large mold frame pad.

[0010] In the above description, a further solution is provided, wherein the ejector block is L-shaped, both ends of the small mold frame spring plate are provided with buckling positions matching the ejector block, and the ejector block is connected to the ejector plate of the large mold frame by bolts.

[0011] In the above description, a further solution is provided in which a supporting top block is provided on the top surface of the small mold frame spring plate. The supporting top block is in a circular structure and is distributed around the top surface of the small mold frame spring plate and is connected to the small mold frame spring plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are: by adopting a detachable male template and a fixed plate, when facing different cases, the staff can achieve the effect of replacement and exchange by replacing different male templates. At the same time, after the terminal is formed, the staff can use the mold frame ejector to eject the mold three times, one time for the material head to be detached, two times for the product to be detached, and three times for the material strip to be pulled, thereby improving work efficiency.

[0013] The solution of using a small mold frame is convenient for disassembly, assembly and maintenance, saving the time of putting the mold base on and off the machine. At the same time, a single mold base can be adapted to multiple small mold frames to save mold opening costs and shorten the initial mold opening and sample delivery cycle.

[0014] At the same time, compared with the two-time ejection solution, the three-time ejection solution has an additional step to eject the material head first, which reduces the pressure on the gate parts and increases the service life. Cutting off the gate first also reduces the resistance of product ejection, which can obtain products with better appearance; it also has certain optimization for product deformation, and the reduction of resistance invisibly increases the service life of the ejector pin and saves costs.

[0032] Second ejection: The ejector rod 9 of the small mold frame is pushed to touch the ejector plate 7 of the large mold frame by the ejector rod of the machine platform. The ejector plate 7 of the large mold frame pushes the ejector plate 6 of the large mold frame to move upward, and at the same time, the ejector rod 13 and the ejector plate of the small mold frame are driven to push upward, and the reset spring 14 is compressed to eject the product and the material strip synchronously;
