Description

Technical Field

[0001] This utility model relates to the technical field of molds, and more specifically, to a casting mold that is easy to demold. Background Technology

[0002] In industrial production, metal casting is a very common method for manufacturing workpieces, especially for the mass production of small parts, where it offers significant advantages. Typically, multiple interconnected mold slots are set between two mold plates, and a unified pouring gate is used to cast multiple mold slots in a single process. This method greatly improves production efficiency and reduces production costs.

[0003] However, this process also has certain drawbacks. When the molten metal cools and solidifies, the formed workpieces, being interconnected, are prone to sticking together in the mold cavity. At this point, manual demolding is often required, commonly using methods such as tapping the mold or using vibration equipment to force the workpieces to detach. However, these methods are quite time-consuming and labor-intensive, not only extending the production cycle and increasing labor costs, but also potentially damaging the workpieces due to improper operation, affecting product quality. For example, in some small hardware processing plants, workers spend a significant amount of time each day on demolding, making it difficult to improve production efficiency, and frequent tapping causes surface defects on some workpieces, resulting in a high scrap rate. Therefore, developing a mold that facilitates demolding is urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide a casting mold that facilitates demolding, which can automatically assist in demolding after the mold is separated, thereby improving demolding efficiency.

[0005] This utility model is achieved through the following technical solution: The casting mold of this utility model, which facilitates demolding, includes a horizontally arranged lower template, multiple concave molds opened on the upper side of the lower template, an upper template located above the lower template, multiple convex molds located on the lower side of the upper template, a runner located in the middle of the upper side of the lower template, a demolding module located at the bottom of the runner, a guide channel for connecting the runner and the concave molds, a first sprue located on the lower template, and a second sprue located on the lower side of the upper template; the concave molds and the convex molds correspond one-to-one, the first sprue and the second sprue are adapted to each other, both the first sprue and the second sprue are connected to the runner, and the demolding module is detachably connected to the upper template.

[0006] Furthermore, the plurality of said concave dies are circumferentially distributed in the lower template, and the plurality of said convex dies are circumferentially distributed in the upper template.

[0007] Furthermore, the side wall of the diversion channel is provided with a slot, and a connecting block is provided in the slot. The connecting block is fixedly connected to the detachable module, and the connecting block is detachably connected to the upper template.

[0008] Furthermore, the upper template has an insertion hole, and the connecting block can be detachably inserted into the insertion hole.

[0009] Furthermore, a pair of fixing blocks are provided on the upper side of the upper template. The fixing blocks have a first fixing hole. The connecting block extends upward after passing through the insertion hole. A second fixing hole is provided on the side wall of the connecting block. The pair of fixing blocks are respectively provided on opposite sides of the insertion hole. A pin is inserted into the second fixing hole. The two ends of the pin are respectively inserted into the pair of first fixing holes.

[0010] Furthermore, the lower template is provided with a plurality of vertically arranged limiting rods on its upper side, and the upper template is provided with a plurality of limiting holes; one of the limiting rods is inserted into one of the limiting holes.

[0011] Furthermore, the upper template is provided with multiple hanging rings on its upper side.

[0012] The technical solution of this utility model has at least the following advantages and beneficial effects: The casting mold of this utility model, which facilitates demolding, connects the demolding module to the upper template during use. The upper template is then pressed onto the lower template, ensuring a one-to-one correspondence between the punch and die. The demolding module is engaged at the bottom of the runner. Molten metal is then injected into the runner through the first and second runners, and then flows into each die through the guide channel, solidifying to form the workpiece. During demolding, a lifting device lifts the upper template. Because the upper template is connected to the demolding module, and the demolding module is at the bottom of the runner, the upper template will lift the demolding module. Since the workpieces in the dies are connected as a single unit through the guide channel and the metal blocks in the runner, the demolding module will lift the metal blocks in the runner, thus pulling the workpieces from each die. This eliminates the need for manual hammering during demolding, effectively improving demolding efficiency, reducing worker labor intensity, and avoiding complicated operating procedures. It also does not adversely affect the casting quality of the workpiece itself. Attached Figure Description

Detailed Implementation

[0022] Example

[0023] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 8As shown, the casting mold for easy demolding in this embodiment includes a horizontally arranged lower template 10, multiple concave molds 11 opened on the upper side of the lower template 10, an upper template 20 located above the lower template 10, multiple convex molds 21 located on the lower side of the upper template 20, a runner 12 located in the middle of the upper side of the lower template 10, a demolding module 30 located at the bottom of the runner 12, a guide channel 13 for connecting the runner 12 and the concave molds 11, a first sprue 14 located on the lower template 10, and a second sprue 22 located on the lower side of the upper template 20; the concave molds 11 and convex molds 21 correspond one-to-one, the first sprue 14 and the second sprue 22 are adapted to each other, the first sprue 14 and the second sprue 22 are both connected to the runner 12, and the demolding module 30 is detachably connected to the upper template 20. Specifically, during use, the ejector module 30 is connected to the upper template 20, and then the upper template 20 is pressed onto the lower template 10, so that the punch 21 and the die 11 correspond one-to-one. The ejector module 30 is then inserted into the bottom of the runner 12. The molten metal is then injected into the runner 12 through the first runner 14 and the second runner 22, and then enters each die 11 through the guide channel 13. After solidification, the workpiece 40 is formed. During demolding, a lifting device is used to lift the upper template 20. Since the upper template 20 is connected to the demolding module 30, and the demolding module 30 is located at the bottom of the flow divider 12, the upper template 20 will drive the demolding module 30 to rise. Since the workpiece 40 in the die 11 is connected as a whole structure through the guide channel 13 and the metal block in the flow divider 12, the demolding module 30 will drive the metal block in the flow divider 12 to rise, thereby pulling the workpiece 40 in each die 11 out of the die 11. There is no need for manual knocking demolding, which can effectively improve demolding efficiency, reduce the labor intensity of workers, and eliminate the need for complicated operation steps. It will not have an adverse effect on the casting quality of the workpiece 40 itself.

[0024] In this embodiment, multiple concave dies 11 are circumferentially distributed in the lower mold plate 10, and multiple convex dies 21 are circumferentially distributed in the upper mold plate 20. Specifically, the concave dies 11 and convex dies 21 are evenly arranged on the lower mold plate 10 and the upper mold plate 20, and the length of each guide groove 13 is the same, so that the molten metal in the flow channel 12 is injected into the concave die 11 at the same time. However, space needs to be reserved in the lower mold plate 10 and the upper mold plate 20 for the first gating 14 and the second gating 22. When the upper mold plate 20 and the lower mold plate 10 are closed, the first gating 14 and the second gating 22 combine to form a gating with a circular cross-section.

[0025] In this embodiment, the side wall of the diversion channel 12 is provided with a slot 15, and a connecting block 31 is provided in the slot 15. The connecting block 31 is fixedly connected to the demolding module 30 and detachably connected to the upper template 20. Specifically, before the upper template 20 and the lower template 10 are closed, the connecting block 31 is fixed on the upper template 20. Then, the upper template 20 and the lower template 10 are heated as a whole. After heating, the mold is closed. After the mold is closed, molten metal is poured in. After solidification, the upper template 20 is lifted, and the workpiece 40 is taken out from the lower template 10 through the connecting block 31 and the demolding module 30. Then, the connecting block 31 is separated from the upper template 20, and the connecting block 31, the demolding module 30, and the workpiece 40 are separated from the upper template 20. At this time, a new demolding module 30 and a new connecting block 31 can be connected to the upper template 20. Subsequently, the demolding module 30 connected to the workpiece 40 can be separated and recycled.

[0026] In this embodiment, the upper template 20 has an insertion hole 25, and the connecting block 31 is detachably inserted into the insertion hole 25. A pair of fixing blocks 23 are provided on the upper side of the upper template 20. The fixing blocks 23 have a first fixing hole. The connecting block 31 passes through the insertion hole 25 and extends upward. A second fixing hole 32 is provided on the side wall of the connecting block 31. The pair of fixing blocks 23 are respectively provided on opposite sides of the insertion hole 25. A pin 24 is inserted into the second fixing hole 32. The two ends of the pin 24 are respectively inserted into the pair of first fixing holes. Specifically, when installing the connecting block 31 and the detaching module 30 onto the upper template 20, the connecting block 31 is passed through the insertion hole 25 from the lower side of the upper template 20, and then the pin rod 24 is simultaneously inserted into the first fixing hole and the second fixing hole 32 to fix the connecting block 31 and the detaching module 30 onto the upper template 20. After the upper template 20 and the lower template 10 are separated, the pin rod 24 can be knocked out of the first fixing hole and the second fixing hole 32 to separate the workpiece 40, the upper template 20 and the detaching module 30.

[0027] In this embodiment, the lower template 10 is provided with a plurality of vertically arranged limiting rods 16 on its upper side, and the upper template 20 is provided with a plurality of limiting holes 26; one limiting rod 16 is inserted into one limiting hole 26. Specifically, through the cooperation of the limiting rods 16 and the limiting holes 26, the upper template 20 and the lower template 10 can be precisely molded together.

[0028] In this embodiment, the upper template 20 is provided with multiple hanging rings 27 on its upper side. Specifically, the hanging rings 27 are mainly used to connect the upper template 20 to the lifting machine, so as to facilitate the lifting of the upper template 20. The upper template 20 can be lifted using a telescopic rod (such as a hydraulic cylinder) or an electric hoist. At this time, the lower template 10 can be fixed to the ground or the base.

[0029] In summary, the casting mold of this embodiment, which facilitates demolding, is used by connecting the demolding module 30 to the upper template 20, then pressing the upper template 20 onto the lower template 10, so that the punch 21 and the die 11 correspond one-to-one, and the demolding module 30 is inserted into the bottom of the runner 12. Then, the molten metal is injected into the runner 12 through the first runner 14 and the second runner 22, and then enters each die 11 through the guide channel 13. After solidification, the workpiece 40 is formed. During demolding, a lifting device is used to lift the upper template 20. Since the upper template 20 is connected to the demolding module 30, and the demolding module 30 is located at the bottom of the flow divider 12, the upper template 20 will drive the demolding module 30 to rise. Since the workpiece 40 in the die 11 is connected as a whole structure through the guide channel 13 and the metal block in the flow divider 12, the demolding module 30 will drive the metal block in the flow divider 12 to rise, thereby pulling the workpiece 40 in each die 11 out of the die 11. There is no need for manual knocking demolding, which can effectively improve demolding efficiency, reduce the labor intensity of workers, and eliminate the need for complicated operation steps. It will not have an adverse effect on the casting quality of the workpiece 40 itself.

Various modifications and variations can be made to this utility model by those skilled in the art.
