Technical Field

[0001] The utility model belongs to the technical field of forming molds, and in particular relates to a conical mold positioning device. Background Art

[0002] In the composite material molding process, when multiple core molds are combined, pins are generally used to fasten the connection. However, when the pins encounter a large shear force, they will bend and deform, and the pin holes will deform, resulting in deviations after the core blocks are combined. Deviations in the overall profile will occur, which does not meet the profile requirements. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0022] like Figure 1 to Figure 7 As shown, a conical mold locator includes: a locator male head 11 installed on the side mold; a locator female head 12 installed on the core mold 20; wherein, when the side mold is molded with the core mold 20, the side mold is connected with the corresponding locator female head 12 on the core mold 20 through the locator male head 11, and after a number of side molds are molded with the core mold, a molding surface matching the surface of the product to be molded is obtained.

[0023] The technical solution of the utility model is further explained below by taking the application of the conical mold positioner in the assembly of the air intake mold.

[0024] like Figure 1 As shown, the air inlet mold includes a conical mold locator 10, a core mold 20, a left side mold 30 and a right side mold 40. Only the conical mold locator 10 can be used to accurately connect the core mold and the side mold without using pins, thereby reducing the workload of traditional mold closing and demolding using pins and bolts.

[0025] like Figure 2As shown in the partial enlarged view, it can be seen that the conical mold clamping locator 10 is a combination, consisting of a locator male head 11 and a locator female head 12. The locator male head 11 is embedded in the first mounting groove of the right side mold 40 for installation and fixation, and the locator female head 12 is embedded in the second mounting groove of the core mold 20 for installation and fixation. Through the bite assembly mode of the locator male head 11 and the locator female head 12, the purpose of accurately and firmly combining the core mold 20 and the right side mold 40 is achieved, and the fixing mode of the other side molds and the core mold 20 is the same.

[0026] like Figure 3 As shown, the right side mold 40 moves relative to the core mold 20, and the right side mold 40 moves relative to the rear. At this time, the male locator 11 and the female locator 12 are disengaged, and the right side mold 40 can be separated from the core mold 20. No screws need to be removed during the mold separation process.

[0027] like Figure 4 As shown, there are front slide grooves 21 and rear slide grooves 23 on the rear side of the locator female head 12, which are used for the guided sliding of the locator male head 11. Each slide groove has a trapezoidal opening 22 on the rear side, which facilitates the locator male head 11 to slide into the guide slide groove. Among them, the depth of the rear slide groove 23 is greater than the front slide groove 21. The reason is that if the depths of the two slide grooves are the same, the installation heights of the front and rear locator female heads 12 are the same. When the locator male head 11 of the front conical mold locator 10 slides backward, it will interfere with the locator female head 12 on the rear side. Therefore, the installation height of the locator female head 12 on the same sliding axis needs to be deepened successively, and the depth of the slide groove also needs to be deepened successively. It is necessary to ensure that the top of the rear locator female head 12 after installation is lower than the protruding part of the front locator male head 11.

[0028] like Figure 5~Figure 7 As shown, the male locator 11 is hook-shaped, comprising: a first base; a conical plug disposed on the first base, the conical plug having a hook-shaped conical surface 111. The female locator 12 comprises: a second base; a conical socket disposed on the second base and matching with the conical plug, the conical socket having a conical surface 121 matching with the hook-shaped conical surface 111.

[0029] The hook-shaped conical surface 111 cooperates with the conical surface 121 of the positioner female head 12 to lock the core molds of the air inlet mold to each other. The first base has a first mating surface 112, and the second base has a second mating surface 122. When the positioner male head 11 and the positioner female head 12 are plugged into each other, there is a set spacing between the first mating surface 112 and the second mating surface 122, which is used to reserve a clamping margin to avoid the mold being unclamped due to processing errors, thereby causing the composite material parts after molding to have a step problem due to the unclamped gap at the position where the molds contact each other.

[0030] The first base has a first mounting surface 113 for connecting to the side mold, the first mounting surface 113 cooperates with the first mounting groove set on the side mold and is fixed with a countersunk screw; the second base has a second mounting surface 123 for connecting to the core mold 20, the second mounting surface cooperates with the second mounting groove set on the core mold 20 and is fixed with a countersunk screw to avoid interference of the screws with the relative sliding of the locator.

[0031] The conical plug has a first limiting side surface 114, and the second base has a second limiting side surface 124 that matches the first limiting side surface 114. A portion of the first limiting side surface 114 of the conical plug is inserted into the conical groove of the positioner female head 12 and contacts the two second limiting side surfaces 124, playing the role of limiting on both sides. Another portion of the two first limiting side surfaces 114 of the conical plug contacts the two side surfaces of the front slide groove 21 and the rear slide groove 23 of the core mold 20, and similarly plays the role of limiting on both sides.

[0032] The connection between the core molds of the utility model is made by means of a positioning plug and a positioning socket, so that the upper, lower, left and right core blocks are more closely attached to the middle core mold, so that the core mold is not easy to deform, and the inner wall of the air inlet product is not easy to have a step difference. The removal of the pins between the core molds is reduced during demolding and mold closing, reducing labor costs. The application of the positioning plug and the positioning socket reduces the mold closing gap caused by the bending of the mold, reduces the positioning deviation of the pin to the core mold connection, and ensures the smoothness of the inner surface of the air inlet.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
