preferably, left groove and right groove are symmetrical arranged about the splicing seams of left module and right module.Molding is convenient.
preferably, snap close piece has two, and two snap close pieces respectively vertical with the cross section of right module splicing with left module, be arranged on mud core box both sides.
according to a concrete enforcement of the present utility model and preferred aspect, snap close piece horizontal cross-section is " [" shape, it is described that " vertical edge of [" shape is vertical with the cross section of right module splicing with left module, and described " the both ends widthwise edge of [" shape is buckled on the side of left module and right module.
according to another concrete enforcement of the present utility model and preferred aspect, on the cross section of left module and the splicing of right module, be provided with pin-and-hole respectively, mud core box also comprises that both ends are plugged in respectively the lock pin in pin-and-hole.
further, preferably embodiment is provided with pin-and-hole on the cross section of left module and the splicing of right module, on the cross section of right module and the splicing of left module, is fixed with the lock pin matching with pin-and-hole; On the cross section of right module and the splicing of left module, be provided with pin-and-hole, on the cross section of left module and the splicing of right module, be fixed with the lock pin matching with pin-and-hole.
due to the enforcement of above technical scheme, the utility model compared with prior art tool has the following advantages:
left module and right module that the utility model adopts left and right to arrange, in left and right module, be respectively equipped with left and right groove, the die cavity being spliced into by left and right groove is identical with the profile of pump cover oil groove, and under the effect of snap close piece, meets the condition of pump cover oil groove moulding, while getting core simultaneously, only need to remove snap close piece, slough left and right module, guarantee the integrity degree of mud core, reduce the corner of mud core and damage, improve and get core efficiency simultaneously.
Accompanying drawing explanation
below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in more detail.
fig. 1 is according to the main cross-sectional schematic of the utility model mud core box;
fig. 2 is the schematic top plan view of Fig. 1;
wherein: 1, left module; 10, left groove; 2, right module; 20, right groove; 3, snap close piece; 4, die cavity; 5, splicing seams; A, pin-and-hole; B, lock pin.
The specific embodiment
as depicted in figs. 1 and 2, the mud core box that is exclusively used in production pump cover oil groove of the present embodiment, this pump cover oil groove is cylindrical, its mud core box has about two the left modules 1 that arrange and right module 2 and for by a plurality of snap close pieces 3 of left module 1 locking relative to right module 2, left module 1 and right module 2 are respectively equipped with left groove 10 and right groove 20, left groove 10 is spliced into the die cavity 4 identical with pump cover oil groove profile with right groove 20, the degree of depth of left groove 10 and right groove 20 equates with the height of pump cover oil groove, and is 2/3rds of left module 1 or right module 2 thickness.
above-mentioned left groove 10 and right groove 20 are symmetrical arranged about the splicing seams 5 of left module 1 and right module 2, and left module 1 and right module 2 are also symmetrical arranged about splicing seams 5 simultaneously.Further, in this example, snap close piece 3 has two, and two snap close pieces 3 respectively vertical with the cross section of right module 2 splicings with left module 1, be arranged on mud core box both sides, these snap close piece 3 horizontal cross-sections are " [" shape, it is described that " vertical edge of [" shape and the cross section vertical (with splicing seams 5 vertical) of left module 1 with right module 2 splicings, described " the both ends widthwise edge of [" shape is buckled on the side of left module 1 and right module 2.
in addition, in order to make the more stable splicing of left and right module 1,2, on the cross section of left module 1 and 2 splicings of right module, be provided with pin-and-hole a respectively, mud core box also comprises that both ends are plugged in respectively the lock pin b in pin-and-hole a, the setting of pin-and-hole a and lock pin b simultaneously also has following two kinds, on the cross section of left module 1 and 2 splicings of right module, be provided with a pin-and-hole a, on the cross section of right module 2 and 1 splicing of left module, be fixed with the lock pin b matching with pin-and-hole a; Another kind is to be provided with pin-and-hole a on the cross section of right module 2 and 1 splicing of left module, on the cross section of left module 1 and 2 splicings of right module, be fixed with the lock pin b matching with pin-and-hole a, in this example, adopt that pin-and-hole a arranges in left module 1, lock pin b is fixedly installed in right module 2, adding " the snap close piece 3 of [" shape simultaneously, left module 1 and right module 2 are linked together, intensity is higher, and splicing seams 5 is less.
