Description

Technical Field

[0001] This utility model relates to the field of flange mold technology, specifically a machine tool transmission shaft flange mold. Background Technology

[0002] Machine tool drive shaft flange molds are molds used to manufacture flanges, a type of connecting component. Flanges, as a type of round metal part, are usually used to connect two parts or to external equipment. In machine tools, they play the roles of connection, sealing, and enhancing stability.

[0003] Existing flange molds, such as the flange mold disclosed in publication number CN218983079U, involve pouring the casting liquid directly into the flange mold cavity through a pouring pipe during flange casting. However, the splashing of the casting liquid during direct pouring can easily generate air bubbles. Furthermore, the air is evacuated by connecting an air extraction rod to the upper end of the heat dissipation pipe. The negative pressure generated when evacuating the flange mold cavity through the heat dissipation pipe will affect the stability of the casting liquid, resulting in poor air bubble elimination. Therefore, we propose a machine tool transmission shaft flange mold. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A machine tool transmission shaft flange mold includes: a mold body and a casting assembly; the mold body includes an upper module and a lower module at the upper and lower ends, a base plate fixedly installed at the bottom of the lower module, a top material component installed at the upper end of the base plate, a mold core fixedly installed at the bottom of the upper module, and a mold cavity opened at the top of the lower module; the casting assembly includes an installation cavity opened at the center of the upper module, a casting cylinder movably installed at the center of the installation cavity, a first casting tube and a second casting tube fixedly connected to the bottom sides of the casting cylinder respectively, vent holes correspondingly opened on both sides of the upper module and the mold core, a connecting rod fixedly installed on one side of the bottom of the casting cylinder, a screw sleeve fixedly installed at the outer end of the connecting rod, and a screw component movably installed inside the screw sleeve.

[0007] Preferably, a servo motor is also fixedly installed on one side of the top of the upper module, and the lower part of the servo motor is fixedly connected to the top of the lead screw.

[0008] Preferably, a lower positioning sleeve and an upper positioning sleeve are fixedly installed on the lower and upper parts of the lead screw, respectively, and the outer sides of the lower positioning sleeve and the upper positioning sleeve are fixed to the inner wall of the mounting cavity.

[0009] Preferably, a restraining rod is fixedly installed on one side of the lower part of the casting cylinder, and a restraining groove is also provided on one side of the installation cavity.

[0010] Preferably, the outer side of the restraint rod is movable within the restraint groove.

[0011] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0012] 1. In this utility model, when casting the flange mold cavity between the upper and lower modules, a fixed amount of casting liquid is slowly injected into the casting cylinder in the upper module. After the casting cylinder is stable, the casting cylinder is lifted by the servo motor-driven screw component. This allows the first and second casting tubes at the bottom of the casting cylinder, located at the bottom of the flange mold cavity, to slowly inject the internal casting liquid into the flange mold cavity. The injection is carried out layer by layer during the lifting process, thereby ensuring the stable injection of casting liquid during flange casting and avoiding the problem of air bubbles in the flange caused by splashing during direct casting.

[0013] 2. In this utility model, the lower positioning sleeve and the upper positioning sleeve at the upper and lower ends of the lead screw can position the micro-position of the first and second casting tubes at the bottom of the casting cylinder, and can also position the lifting height of the first and second casting tubes so that they can be positioned and lifted into the mold core after casting.

[0019] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0020] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a machine tool transmission shaft flange mold.

[0021] Example 1:

[0022] Combination Figure 1-2 As shown, the present invention provides a machine tool transmission shaft flange mold, comprising: a mold body 100 and a casting assembly 200; the mold body 100 includes an upper module 101 and a lower module 102 at the upper and lower ends, a base plate 103 fixedly installed at the bottom of the lower module 102, a top material component 104 installed at the upper end of the base plate 103, a mold core 105 fixedly installed at the bottom of the upper module 101, and a mold cavity 106 opened at the top of the lower module 102; the casting assembly 200 includes an installation cavity 201 opened at the center of the upper module 101, a casting cylinder 202 movably installed at the center of the installation cavity 201, a first casting tube 203 and a second casting tube 204 fixedly connected to the bottom sides of the casting cylinder 202 respectively, and venting openings corresponding to both sides of the upper module 101 and the mold core 105. The connection rod 206 is fixedly installed on one side of the bottom of the casting cylinder 202. The lead screw sleeve 207 is fixedly installed on the outer end of the connecting rod 206. The lead screw component 208 is movably installed inside the lead screw sleeve 207. A servo motor 209 is also fixedly installed on one side of the top of the upper module 101. The lower part of the servo motor 209 is fixedly connected to the top of the lead screw component 208. The lower part and the upper part of the lead screw component 208 are respectively fixedly installed with a lower positioning sleeve 210 and an upper positioning sleeve 211. The outer sides of the lower positioning sleeve 210 and the upper positioning sleeve 211 are fixed to the inner wall of the installation cavity 201. A restraining rod 212 is also fixedly installed on one side of the lower part of the casting cylinder 202. A restraining groove 213 is also opened on one side of the installation cavity 201. The outer side of the restraining rod 212 is movably matched in the restraining groove 213.

[0023] Specifically, the machine tool drive shaft flange mold is a mold used to manufacture flanges, a type of connecting component. During casting, the flange mold cavity 106 between the upper module 101 and the lower module 102 in the mold body 100 only requires a measured amount of casting liquid to be slowly injected into the casting cylinder 202 in the upper module 101. After stabilizing within the casting cylinder 202, the casting cylinder 202 is then lifted by the servo motor 209 driving the lead screw 208. This allows the first and second casting tubes 203 and 204, located at the bottom of the casting cylinder 202 and at the bottom of the flange mold cavity 106, to smoothly inject the casting liquid into the flange mold cavity 106 during the slow lifting process. This layered injection during lifting ensures a stable injection of the casting liquid during flange casting, avoiding the problem of air bubbles in the flange caused by splashing during direct casting. The bottoms of the thin tube 203 and the second casting thin tube 204 are kept at a slight distance from the bottom of the mold cavity 106, which helps to avoid air bubbles when the quantitative casting liquid is injected into the casting cylinder 202. The vent holes 205 on both sides of the upper module 101 are mainly used for venting during casting in the mold cavity 106. At the same time, the lower positioning sleeve 210 and the upper positioning sleeve 211 at the upper and lower ends of the screw component 208 can position the slight distance between the first casting thin tube 203 and the second casting thin tube 204 at the bottom of the casting cylinder 202, and can also position the lifting height of the first casting thin tube 203 and the second casting thin tube 204 so that they can be positioned and lifted into the mold core 105 after casting. The binding rod 212 fixedly connected to the lower part of the casting cylinder 202, and the binding groove 213 binding the outer side of the binding rod 212 are mainly used to ensure the stability of the casting cylinder 202 during the overall lifting.

[0024] Working principle and usage process of this utility model:

[0025] When casting the flange cavity 106 between the upper module 101 and the lower module 102 within the mold body 100, a measured amount of casting liquid is first gently injected into the casting cylinder 202. As the casting liquid is injected into the casting cylinder 202, it flows downstream into the first casting tube 203 and the second casting tube 204 on both sides of the bottom of the casting cylinder 202. Air is released during casting through the micro-space reserved at the bottom of the first casting tube 203 and the second casting tube 204 to prevent air bubbles from forming in the casting liquid injected into the casting cylinder 202. After the casting liquid in the casting cylinder 202 stabilizes, the servo motor 208 on the top of the upper module 101 can be started. After 209 is started, the screw 209 in the installation cavity 201 will rotate, so that the casting cylinder 202 in the installation cavity 201 will be slowly lifted by the rotating screw 208. During the lifting of the casting cylinder 202, the first casting tube 203 and the second casting tube 204 on both sides of its bottom will be lifted synchronously and smoothly on both sides of the bottom of the mold cavity 106. During the lifting, the casting liquid inside them will be smoothly injected into both sides of the bottom of the mold cavity 106. Then, following the lifting of the casting cylinder 202, the casting liquid will be injected layer by layer through the bottom of the mold cavity 106, so as to carry out layer-by-layer and smooth casting in the flange mold cavity 106 to prevent the formation of air bubbles during casting.
