Description

Technical Field

[0001] The utility model relates to the field of casting moulds, in particular to a high-temperature casting mould with a protection mechanism. Background Art

[0002] A casting mold is a tool that makes the blank become a casting with a specific shape and size under the action of external force. A casting mold generally consists of two parts: an upper mold (movable mold) and a lower mold (fixed mold). The two parts can be separated or combined. When separated, the workpiece can be taken out, and when combined, the blank can be injected into the mold cavity for forming.

[0003] During the mold forming process of the product, in order to avoid the upper and lower molds from shifting or separating, resulting in the workpiece having more burrs or even becoming waste after forming, the staff needs to fix the upper and lower molds with bolts and nuts. However, the installation of bolts and nuts requires manual operation, which is time-consuming and labor-intensive. If electric products such as cylinders, electric push rods, and hydraulic cylinders are used for pressing, the reciprocating operation also needs to be connected to electricity, which is not economical and environmentally friendly.

[0004] Therefore, it is necessary to invent a high temperature casting mold with a protective mechanism. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-temperature casting mold with a protection mechanism, including a mold mechanism, the mold mechanism including a base and a lower mold installed on the upper end of the base, an upper mold installed on the upper end of the lower mold, a fixing plate is provided on the outside of the lower mold and the upper mold, anti-slip strips are connected on both sides of the fixing plate, a molding cavity is provided in the middle of the lower mold, a through hole is provided on the surface of the molding cavity, and a ejector pin is movably penetrated inside the through hole.

[0007] Based on the above characteristics: when the lower mold and the upper mold need to be connected, the upper mold can be pressed down on the upper end of the lower mold, and then the fixed plate is slidably connected to the outside of the lower mold and the upper mold on both sides, and finally the anti-slip strip is used to limit the fixed plate to prevent it from moving left and right again. At this time, the lower mold and the upper mold will be tightly connected together, without the need for bolts to fix, and finally the metal casting liquid can be introduced into the molding cavity.

[0008] Preferably, guide grooves are symmetrically provided on both sides of the base, a positioning slot and a cooling port are provided on the upper surface of the base, and the positioning slots are symmetrically provided on both sides of the molding cavity.

[0009] Based on the above features: the guide groove can limit the lower end of the fixed plate, and the cooling pipe can be connected to the cooling port to facilitate the flow of coolant to perform heat exchange cooling on the formed workpiece.

[0010] Preferably, a runner is provided in the middle of the upper mold, positioning rods are symmetrically installed on both sides of the lower end of the upper mold, and positioning tooth plates are installed at the lower ends of the positioning rods.

[0011] Based on the above characteristics: the metal casting liquid enters the molding cavity through the runner for casting and molding. When the upper mold is pressed down to the upper end of the lower mold, the upper mold will use the positioning rod and the positioning tooth plate to insert into the positioning slot, so that the upper mold and the lower mold can be quickly positioned and aligned.

[0012] Preferably, L-shaped baffles are symmetrically installed on both sides of the fixed plate, convex plates are symmetrically installed on both sides of the lower end of the fixed plate, and a guide slider is fixedly installed on the lower end of the convex plate.

[0013] Based on the above characteristics: the fixed plate is slidably connected with the guide slide groove by the guide slider at the lower end of the convex plate. At this time, the fixed plate cannot move up and down, and can only move to the side away from the lower mold and the upper mold. Then the anti-slip strip is inserted into the inner side of the L-shaped baffle for limiting.

[0014] Preferably, limit plates are symmetrically installed on both sides of the anti-slip strip.

[0015] Based on the above features: the anti-slip strip uses the limiting plates on both sides to limit the L-shaped baffle, so that two adjacent fixed plates cannot move away from each other.

[0016] Preferably, a connecting tooth plate is installed at the lower end of the ejector pin, one side of the connecting tooth plate is meshedly connected with a driving gear A, the side of the driving gear A away from the connecting tooth plate is meshedly connected with a driving gear B, a rotating shaft is installed between the driving gear A and the driving gear B, and bearing seats are symmetrically installed on both sides of the rotating shaft.

[0017] Based on the above characteristics: when the upper mold is pressed down to insert the positioning rod and the positioning tooth plate into the positioning slot, the positioning tooth plate will engage with the driving gear B, so that the driving gear B and the driving gear A can drive the ejector pin to move downward through the connecting tooth plate; when the upper mold is pulled up to disengage the positioning rod and the positioning tooth plate from the positioning slot, the positioning tooth plate can also drive the driving gear B and the driving gear A to reverse. At this time, the driving gear A will drive the ejector pin to move upward to eject the workpiece in the molding cavity.

[0018] Preferably, the diameter of the ejector pin is the same as the inner diameter of the through hole, and the diameter of the connecting tooth plate is larger than the through hole.

[0019] Based on the above characteristics: the ejector pin can pass through the through hole for telescopic adjustment, while the connecting tooth plate cannot pass through the through hole, thereby preventing the ejector pin from being separated from the through hole.

[0020] The beneficial effects of the utility model are:

[0021] 1. Anti-slip protection can be performed after the lower mold and the upper mold are connected. When the lower mold and the upper mold need to be connected, the positioning rod and the positioning tooth plate at the lower end of the upper mold will be inserted into the positioning slot for quick positioning. Then the fixed plate is slidably connected with the guide slide groove by the guide slider. When the guide slider fits the inner wall of one side of the guide slide groove and cannot move the fixed plate, the anti-slip strip can be inserted into the inner side of the L-shaped baffle for limiting the position, so that the fixed plate cannot be displaced up, down, left, and right. This can not only prevent the fixed plate from detaching from the lower mold and the upper mold, but also prevent the lower mold and the upper mold from separating. When disassembly is required, just pull the anti-slip strip upwards first, then pull the fixed plate to both sides, and finally lift the upper mold upwards. It is simple and convenient.

[0022] 2. When the positioning rod and the positioning tooth plate are inserted into the positioning slot, the positioning tooth plate will mesh with the driving gear B, so that when the driving gear B rotates, it can drive the driving gear A to rotate synchronously. When the driving gear A82 rotates, it will drive the ejector pin to move downward through the connecting tooth plate. When the upper mold is pulled up to make the positioning rod and the positioning tooth plate disengage from the positioning slot, the positioning tooth plate can also drive the driving gear B and the driving gear A to reverse. At this time, the driving gear A will drive the ejector pin to move upward to eject the workpiece in the molding cavity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] See attached Figure 1-4 The utility model provides a high-temperature casting mold with a protection mechanism, including a mold mechanism, the mold mechanism includes a base 1 and a lower mold 2 installed on the upper end of the base 1, an upper mold 3 is installed on the upper end of the lower mold 2, a fixing plate 4 is provided on the outside of the lower mold 2 and the upper mold 3, anti-slip strips 5 are connected on both sides of the fixing plate 4, a molding cavity 6 is provided in the middle of the lower mold 2, a through hole 7 is provided on the surface of the molding cavity 6, and an ejector pin 8 is movably penetrated inside the through hole 7.

[0030] When the lower mold 2 and the upper mold 3 need to be connected, the upper mold 3 can be pressed down on the upper end of the lower mold 2. At this time, the ejector pin 8 will also move down synchronously and retract into the through hole 7 (the top surface of the ejector pin 8 is parallel to the top surface of the through hole 7). Then the fixed plate 4 is slidably connected to the outside of the lower mold 2 and the upper mold 3 on both sides. Finally, the anti-slip strip 5 is used to limit the fixing plate 4 to prevent it from moving left and right again. At this time, the lower mold 2 and the upper mold 3 will be tightly connected together without the need for bolts. Finally, the metal casting liquid is introduced into the molding cavity 6. When the metal casting liquid is cooled and formed, it is only necessary to pull the anti-slip strip 5 upwards first, then pull the fixing plate 4 to both sides, and finally lift the upper mold 3 upwards. At this time, the ejector pin 8 will also move upwards to eject the workpiece formed in the molding cavity 6.

[0031] Preferably, guide grooves 11 are symmetrically provided on both sides of the base 1 , a positioning slot 12 and a cooling port 13 are provided on the upper surface of the base 1 , and the positioning slot 12 is symmetrically provided on both sides of the molding cavity 6 .

[0032] The guide chute 11 can limit the lower end of the fixed plate 4, and a cooling pipe can be connected to the cooling port 13 to facilitate the flow of coolant to perform heat exchange cooling on the formed workpiece.

[0033] Preferably, a runner gate 31 is opened in the middle of the upper mold 3 , positioning rods 32 are symmetrically installed on both sides of the lower end of the upper mold 3 , and positioning tooth plates 33 are installed at the lower ends of the positioning rods 32 .

[0034] The metal casting liquid enters the molding cavity 6 through the runner 31 for casting. When the upper mold 3 is pressed down to the upper end of the lower mold 2, the upper mold 3 will use the positioning rod 32 and the positioning tooth plate 33 to insert into the positioning slot 12, so that the upper mold 3 and the lower mold 2 can be quickly positioned and aligned.

[0035] Preferably, L-shaped baffles 41 are symmetrically installed on both sides of the fixing plate 4 , convex plates 42 are symmetrically installed on both sides of the lower end of the fixing plate 4 , and a guide slider 43 is fixedly installed on the lower end of the convex plate 42 .

[0036] The fixed plate 4 is slidably connected to the guide slot 11 by the guide slider 43 at the lower end of the convex plate 42. At this time, the fixed plate 4 cannot move up and down, and can only move to the side away from the lower mold 2 and the upper mold 3. When the guide slider 43 fits with the inner wall of one side of the guide slot 11 and cannot move the fixed plate 4, the anti-slip strip 5 can be inserted into the inner side of the L-shaped baffle 41 for limiting the position, so that the fixed plate 4 cannot move to the side away from the lower mold 2 and the upper mold 3, thereby preventing the fixed plate 4 from detaching from the lower mold 2 and the upper mold 3.

[0037] Preferably, the anti-slip strip 5 is symmetrically provided with limit plates 51 on both sides.

[0038] The anti-slip strip 5 uses the limiting plates 51 on both sides to limit the L-shaped baffle plate 41, so that two adjacent fixing plates 4 cannot move away from each other.

[0039] Preferably, a connecting tooth plate 81 is installed at the lower end of the ejector pin 8, one side of the connecting tooth plate 81 is meshedly connected with a driving gear A82, and the side of the driving gear A82 away from the connecting tooth plate 81 is meshedly connected with a driving gear B83, a rotating shaft is installed between the driving gear A82 and the driving gear B83, and bearing seats 84 are symmetrically installed on both sides of the rotating shaft.

[0040] The driving gear A82 and the driving gear B83 are installed in the inner cavity of the base 1, and the two are located between the through hole 7 and the positioning slot 12. When the upper mold 3 is pressed down to insert the positioning rod 32 and the positioning tooth plate 33 into the positioning slot 12, the positioning tooth plate 33 will engage with the driving gear B83, so that when the driving gear B83 rotates, it can drive the driving gear A82 to rotate synchronously, and when the driving gear A82 rotates, it will drive the ejector pin 8 to move downward through the connecting tooth plate 81. When the upper mold 3 is pulled up to make the positioning rod 32 and the positioning tooth plate 33 disengage from the positioning slot 12, the positioning tooth plate 33 can also drive the driving gear B83 and the driving gear A82 to reverse. At this time, the driving gear A82 will drive the ejector pin 8 to move upward to eject the workpiece in the molding cavity 6.

[0041] Preferably, the diameter of the ejector pin 8 is the same as the inner diameter of the through hole 7 , and the diameter of the connecting tooth plate 81 is larger than the through hole 7 .

[0042] The ejector pin 8 can pass through the through hole 7 for telescopic adjustment, while the connecting tooth plate 81 cannot pass through the through hole 7 , thereby preventing the ejector pin 8 from being separated from the through hole 7 .

[0043] The use process of the utility model is as follows: when the lower mold 2 and the upper mold 3 need to be connected, the upper mold 3 can be pressed down on the upper end of the lower mold 2. At this time, the positioning rod 32 and the positioning tooth plate 33 at the lower end of the upper mold 3 will be inserted into the positioning slot 12. Then, the positioning tooth plate 33 that moves downward will mesh with the driving gear B83, so that when the driving gear B83 rotates, it can drive the driving gear A82 to rotate synchronously. When the driving gear A82 rotates, it will drive the ejector pin 8 to move downward through the connecting tooth plate 81. After the lower mold 2 and the upper mold 3 are attached together, the fixing plate 4 will use the guide slider 43 at the lower end of the convex plate 42 to slide with the guide slide groove 11. The upper mold 3 is then lifted up by pulling the anti-slip strip 5 upward, and the positioning rod 32 and the positioning tooth plate 33 are also moved up and out of the positioning slot 12. At this time, the driving gear B83 and the driving gear A82 are also reversed, so that the connecting tooth plate 81 can push the ejector pin 8 upward to eject the workpiece in the molding cavity 6.

[0044] The above is only a preferred embodiment of the utility model. Any person skilled in the art may modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
