[0020] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0021] Please refer to Figure 1 , the existing scale support 1 schematic diagram, scale support 1 including support and scale part, in die casting die generally design two groups of side pull slide block forming blank, and through machining to complete the final processing of product. Based on the scale preformed hole 11 in the movable die side, the fixed die side forming problem, the present application provides a kind of technical scheme, which will not be stuck, leading to need to dismantle mode time-consuming and laborious or be affected by the deformation of holding force by pulling.
[0022] Specifically, as Figures 2-4 shown, the present application provides a kind of scale support forming die 100, including fixed die assembly 2, movable die assembly 3, fixed die assembly 2 at least including fixed die plate 21, fixed die core 22, movable die assembly 3 at least including movable die plate 31, movable die core 32, movable die plate base 33, movable die plate 31 and movable die plate base 33 between setting ejector pin push plate 34, push plate fixing plate 35, movable die assembly 3 is equipped with auxiliary extension structure for pin 36 for forming scale end preformed hole 11, auxiliary extension structure for pin 36 includes fixed block 361 in movable die plate base 33, with fixed block 361, through the auxiliary extension rod 362 of the movable die plate 31, movable die core 32 of the pin 363 of the movable die plate 31 of the movable die plate 31 and movable die plate base 33, movable die plate 31 is connected, and the pin 363 of the movable die core 32 is connected.
[0023] Specifically, the present application provides a scale bracket forming die 100, which is an improvement on the preformed hole 11 of the scale bracket 1 based on the existing die capable of forming the scale bracket 1. It can be understood that the forming of other parts of the scale bracket 1 except the preformed hole 11 can still be achieved by the original fixed die assembly 2 and movable die assembly 3. That is, it can also be understood that the fixed die plate 21, fixed die core 22, movable die plate 31, movable die core 32, and side extraction slide block mechanism in the original die are all prior art, and the present application only improves the structure of the preformed hole 11 of the scale bracket. Obviously, the fixed die plate 21 and fixed die core 22 in the fixed die assembly 2, the movable die plate 31, movable die core 32, movable die plate base 33, ejector pin push plate 34, and push plate fixing plate 35 in the movable die assembly 3 are all prior art, and therefore will not be described in detail.
[0024] Specifically, based on the prior art described above, the present application designs an auxiliary extension structure 36 for forming a pin in the movable die assembly 3. It can be understood that, compared with the pin forming structure designed in the movable die assembly 3 in the past, the present application eliminates the technical solution of directly designing a longer pin to form the preformed hole 11, thereby avoiding the problem of the pin being stuck and needing to be replaced by disassembling the die, which is time-consuming and laborious. The auxiliary extension structure 36 for forming a pin provided by the present application includes a fixed block 361 provided on the movable die plate base 33, an auxiliary extension rod 362 connected to the fixed block 361 and penetrating the ejector pin push plate 34, push plate fixing plate 35, and movable die plate 31, and a pin 363 connected to the auxiliary extension rod 362 and penetrating the movable die core 32. As can be seen, the present application realizes the forming of the preformed hole 11 by connecting the auxiliary extension rod 362 and the pin 363. It can be understood that the two-section design reduces the probability of the pin being stuck and replaced by disassembling the die. At the same time, compared with the pin 363 being provided on the fixed die side in the past, the pin being provided on the movable die side can reduce the influence of the holding force and avoid the problem of the preformed hole 11 being deformed by tension.
[0025] Specifically, the fixed block 361 is embedded in the movable die plate base 33, and through holes for the auxiliary extension rod 362 to pass through are formed in the ejector pin push plate 34, push plate fixing plate 35, and movable die plate 31. Through holes for the pin 363 to pass through are formed in the movable die core 32.
[0026] Further, the auxiliary extension structure 36 for forming a pin further includes a pin sleeve 364 penetrating the movable die core 32 and corresponding to the auxiliary extension rod 362 for sleeving the pin 363.
[0027] Specifically, the mold pin sleeve 364 is arranged outside the mold pin 363, which can further avoid the problem of the mold pin 363 being stuck. By arranging the sleeve, when the mold pin 363 is stuck, the mold pin sleeve 364 shares part of the force, thereby reducing the probability of being stuck.
[0028] Further, the mold pin 363 is provided with a hanging table 3631 at one end connected to the auxiliary extension rod 362, and the auxiliary extension rod 362 is provided with a clamping groove 3622 for clamping the hanging table 3631 on the outer wall of the end connected to the mold pin 363.
[0029] Specifically, the auxiliary extension rod 362 and the mold pin 363 can also be connected by other means, such as buckle type, hinge type connection, and in this application, the connection is achieved by arranging the clamping groove 3622 of the auxiliary extension rod 362 to clamp the hanging table 3631 of the mold pin 363. It can be understood that the clamping groove 3622 of the auxiliary extension rod 362 is arranged in the hole of the movable mold plate 31, and when the mold pin 363 is connected to the auxiliary extension rod 362 and installed in the movable mold plate 31, the mold pin 363 is limited by the hole of the movable mold plate 31 and the clamping groove 3622 of the auxiliary extension rod 362, and can only move along the axis direction of the auxiliary extension rod 362 under the pulling force or pushing force of the auxiliary extension rod 362 when needed. It can also be understood that when the auxiliary extension rod 36 provided in the application needs to be replaced, the mold does not need to be disassembled, and only the fixing seat needs to be disassembled, and the auxiliary extension rod 362 and the mold pin 363 connected to the auxiliary extension rod 362 can be pulled out to complete the replacement.
[0030] Further, the auxiliary extension rod 362 and the fixed block 361 are connected by bolts.
[0031] Specifically, when the mold pin 363 needs to be replaced, only the bolts need to be loosened, the fixed block 361 is disassembled, and then the auxiliary extension rod 362 and the mold pin 363 connected to the auxiliary extension rod 362 are pulled out to complete the replacement of the mold pin 363, without disassembling the inner membrane.
[0032] It should be pointed out that the fixed block 361 is embedded in the movable mold plate base 33 and connected by bolts. It can be understood that the fixed block 361 is provided with bolt holes connected to the auxiliary extension rod 362, and bolt holes connected to the movable mold plate base 33. In an actual application scenario provided in the application, the bolt holes of the fixed block 361 connected to the auxiliary extension rod 362 are located in the middle of the fixed block 361, and the bolt holes connected to the movable mold plate base 33 are located on both sides of the bolt holes connected to the auxiliary extension rod 362.
[0033] Specifically, in an actual application scenario provided by the present application, the pin sleeve 364 is sleeved in the through hole of the movable mold core 32, the pin 363 is connected to the clamping groove 3622 of the auxiliary extension rod 362 through the hanging table 3631, and then the connected pin 363 and auxiliary extension rod 362 are inserted into the through holes of the movable mold plate base 33, the push plate fixing plate 35 and the movable mold plate 31. At this time, the pin 363 is inserted and extends out of the pin sleeve 364, and finally the auxiliary extension rod 362 is connected with the fixing block 361 through bolts, the fixing block 361 is embedded in the movable mold base bottom plate and fixed to the movable mold plate base 33 through the bolt holes on both sides. When the mold is opened, the prefabricated hole 11 of the scale end part on the scale support 1 formed by the pin is separated through the auxiliary structure, so that the scale support 1 is effectively separated from the fixed mold. When the pin 363 needs to be replaced, the fixing block 361 is disassembled, the auxiliary extension rod 362 is pulled out, and when the auxiliary extension rod 362 is pulled out, the pin 363 clamped by the hanging table 3631 is also pulled out from the auxiliary pin sleeve 364, and the replacement of the pin 363 is completed.
