The technical solution provided by the present application is based on the existing positive pressure template assembly and the counter-pressure template assembly, and the template system of the present application is formed by adding an anti-misalignment positioning mechanism, and then the positive pressure template assembly and the counter-pressure template assembly are fixedly mounted on the casting molding equipment in a mutually adaptive manner; in this way, in the process of boxless sand casting mold molding, the positive pressure template assembly and the counter-pressure template assembly that are sequentially positioned can be aligned and positioned by the anti-misalignment positioning mechanism that is mutually adaptive. The technical problem of misalignment of sand molds in vertical molding lines without boxes due to the lack of misaligned mold structures in the prior art is solved, and the probability of batch misalignment of products on one side due to misaligned boxes, or even the probability of castings being scrapped due to misalignment, is effectively reduced, which can significantly reduce the scrap rate of produced products. Furthermore, the template system provided by the present application only adds an anti-misalignment positioning mechanism to the existing positive pressure template assembly and the reverse pressure template assembly to achieve the problem of preventing template misalignment in the present application, which can effectively achieve the purpose of significantly reducing the production cost of the template system.
[0017] Accordingly, in order to minimize the manufacturing cost of the template system of the present application and facilitate subsequent use and repair and maintenance, the positive pressure template assembly of the present application includes a positive pressure template body 1, a positive pressure cavity molding component group 2 and a supporting and fixing structure, the positive pressure cavity molding component group 2 and the supporting and fixing structure are both arranged on the positive pressure template body 1, and the anti-error positioning mechanism is arranged on the positive pressure template body 1; the reverse pressure template assembly of the present application includes a reverse pressure template body 3, a reverse pressure cavity molding component group 4 and a supporting and fixing structure, the reverse pressure cavity molding component group 4 and the supporting and fixing structure are both arranged on the reverse pressure template body 3, and the anti-error positioning mechanism is arranged on the reverse pressure template body 3. Adapting to the structure of the above-mentioned positive-pressure template assembly and reverse-pressure template assembly, the anti-mistake positioning mechanism of the present application includes a positive-pressure alignment assembly and a reverse-pressure alignment assembly, which are arranged on the positive-pressure template body 1 and the reverse-pressure template body 3 in a manner that is mutually adaptive to each other.

[0018] Furthermore, in order to simplify the structures of the improved positive-pressure alignment and positioning components and the reverse-pressure alignment and positioning components of the present application to the greatest extent, and to facilitate manufacturing, assembly, and subsequent use and repair and maintenance, the positive-pressure alignment and positioning components of the present application include two sets of positive-pressure alignment and positioning component groups, one set of positive-pressure alignment and positioning component groups is respectively arranged at the front and rear ends of the positive-pressure template body 1 along the molding direction of the sand casting mold; the reverse-pressure alignment and positioning components include two sets of reverse-pressure alignment and positioning component groups, one set of reverse-pressure alignment and positioning component groups is respectively arranged at the front and rear ends of the reverse-pressure template body 3 along the molding direction of the sand casting mold; in the process of boxless sand casting mold molding, the positive-pressure template assembly and the reverse-pressure template assembly that are sequentially put into place are aligned and positioned by the two sets of positive-pressure alignment and positioning component groups and the two sets of reverse-pressure alignment and positioning component groups at the corresponding positions. More specifically, each set of positive-pressure alignment and positioning component group and each set of reverse-pressure alignment and positioning component group of the present application respectively include a misalignment module 5, at least one set of fixing bolts 6 and at least two positioning pins 7, and each misalignment module 5 is fixed at the corresponding position of the positive-pressure template body 1 and the reverse-pressure template body 3 by the corresponding fixing bolts 6 and positioning pins 7.
[0019] In summary, this application is compatible with the design and processing of old molds and newly developed molds by adding an anti-mistaken mold structure. The anti-mistaken mold structure can be added, the template processing amount is small, and the cost is low. In addition, the structure is a detachable structure, which is easy to operate and further guarantees the subsequent repair and maintenance of the mold. During the casting process, the sand mold can effectively identify whether there is a mismatched box, the direction of the mismatched box, and the size of the mismatched box; when the sand mold is mismatched, the sand mold for molding observation will not be damaged; at the same time, the scrap rate can be effectively reduced.
[0020] The technical solution of the present application is further described below through specific embodiments:
[0021] The technical problem to be solved by the present application is: when the equipment cannot sensitively identify the wrong box, the mold is optimized at a low cost, which minimizes the unilateral misalignment of the product batch caused by the failure to identify the wrong box.
[0022] The technical solution adopted to solve the above technical problems is: add a misalignment module to the positive pressure plate and the back pressure plate of the casting mold. When the positive pressure plate and the back pressure plate are molding, the misalignment module will be squeezed with the positive and back pressure plates and the molding sand, and will form an observation structure on the sand mold. The operator can directly judge whether the sand mold has a misalignment box by identifying the observation structure.
[0023] The anti-mis-mold structure has no influence on the production modeling, and the production modeling is formed on the molding sand at the same time.
[0024] The positive pressure plate anti-mismatching structure is composed of mismatching modules and positive pressure plate components, which are fixed by pins and bolts.
[0025] The anti-mismatching structure of the back-pressure plate is a mismatching module and a back-pressure plate assembly, which are fixed by pins and bolts.
[0026] The staggered module is a trapezoidal structure with a certain height, width and slope.
[0027] The staggered modules are fixed on both sides of the positive and negative pressure plates and are flush with the end surfaces.
[0028] The anti-mold error structure enables the molding observation structure on the sand mold during molding to directly identify the box error.
[0029] Embodiment 1
[0030] like Figure 1 to Figure 3 The structure provided by the present application is shown, which is compatible with the design and processing of old molds and newly developed molds, and can add a mold error prevention structure, with less template processing and low cost. In addition, the structure is detachable and easy to operate, further ensuring the subsequent repair and maintenance of the mold.
[0031] The positive pressure plate, the misaligned module, the bolts, and the positioning pins of the present application constitute the positive pressure plate anti-misaligned mold structure; the reverse pressure plate, the misaligned module, the bolts, and the positioning pins of the present application constitute the reverse pressure plate anti-misaligned mold structure. Figure 4 The structure shown is used for molding observation during casting molding, which can effectively identify whether there is a mismatch, the direction of the mismatch, and the size of the mismatch. When the sand mold is mismatched, the sand mold for molding observation will not be destroyed; at the same time, the scrap rate can be effectively reduced.
[0032] It should be noted that the height, width and slope of the staggered module structure referred to in this application need to be set according to the actual template. The position of the staggered module fixed on the positive and negative pressure plates needs to be set according to the safe distance of the mold core. The above are all effective in dealing with the interference and size problems in the process of adding staggered modules to mold design.
[0033] In order to solve the problem of mismatch of sand molds in vertical molding line without box casting, reduce product mismatch and reduce scrap rate, under the premise of ensuring low cost and not affecting the sand mold, this application designs a new anti-mismatch structure. During the molding production process, the operator can directly judge whether the sand mold has mismatch, the direction of mismatch and the size of mismatch by identifying and observing the structure. The improvement effect is obvious, and the scrap rate caused by product mismatch is reduced, which can effectively improve the production efficiency. In particular, the structure is low-cost and easy to process and install.
[0034] The specific manufacturing process is that the casting mold is processed with the staggered module as required, the positive and negative pressure plates are processed with pin holes and bolt holes, and the staggered module is fixed to the positive and negative pressure plates. During the molding production process, the operator can directly determine whether the sand mold has staggered boxes by identifying and observing the structure.
[0035] Technical features of the technical solution of this application:
[0036] The mold processing cost is low, both new and old molds are applicable, and the precision is high;
[0037] The sand mold can effectively identify whether there is a misalignment, the direction of the misalignment and the size of the misalignment; when the sand mold is misaligned, the sand mold for molding observation will not be destroyed;
[0038] Meet the requirements of boxless casting for vertical molding lines.
