Description

Technical Field

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

[0002] The principle of casting molds is to inject molten metal into the mold cavity, and then cool and solidify it to form the desired part. After the liquid cools and solidifies, the mold is opened and the desired part is removed, which is called demolding. After demolding, deburring and polishing are usually required.

[0003] The casting mold mainly consists of a matching upper mold and a lower mold, both of which have cavities. Generally, the upper mold can move up and down. During pouring, the upper mold and the lower mold fit together. After the casting is formed and cooled inside the cavity, the upper mold moves upward and separates from the lower mold. However, at this time, the formed casting is still completely inside the cavity of the lower mold. Currently, the demolding pillar is usually lifted manually, but this is quite difficult when demolding heavy castings. Therefore, we propose a casting mold that facilitates demolding. Utility Model Content

[0004] The purpose of this invention is to provide a casting mold that is easy to demold, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a casting mold that facilitates demolding, comprising a lower template and a mounting plate, wherein a vertical rod is connected between the lower template and the mounting plate;

[0006] A cylinder is provided on the mounting plate, and an upper template is connected to the piston rod of the cylinder. The upper template is connected to an upper mold by screws. The upper mold is provided with a flow channel and an upper cavity, and a connecting pipe communicating with the flow channel is provided on the upper template.

[0014] As a preferred embodiment of the casting mold that facilitates demolding according to this utility model, a controller is provided on the base.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The motor drives the lead screw to rotate, which causes the bottom rod to move the top rod upward, thus lifting the demolding column, making it easier to demold heavy castings;

[0017] 2. Adjust the height of the clamping rod by using an electric push rod, and then use an electric telescopic rod to drive the clamping rod to clamp the part of the casting that is higher than the lower mold. When the bottom rod moves upward, the demolding column pushes the bottom of the casting upward, and the clamping rod can clamp the top of the casting and move upward along with the bottom rod and the fixing rod. This improves the stability during demolding and avoids the problem of heavy castings easily tipping over when moved out of the lower mold with only the demolding column for support.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As mentioned in the background section, existing technologies typically involve manually lifting the demolding pillars, which can be laborious when demolding heavy castings. This invention proposes a casting mold that facilitates demolding. Example

[0024] Reference Figures 1 to 3 A casting mold that facilitates demolding includes a lower template 1 and a mounting plate 3, with a vertical rod 2 connecting the lower template 1 and the mounting plate 3.

[0025] A cylinder 4 is provided on the mounting plate 3. An upper template 5 is connected to the piston rod of the cylinder 4. An upper mold 7 is connected to the upper template 5 by screws. The upper mold 7 is provided with a flow channel and an upper cavity 8. A connecting pipe 6 connected to the flow channel is provided on the upper template 5. An external pipe is connected to the connecting pipe 6 for liquid to enter.

[0026] The lower template 1 is connected to the lower mold 9 by screws, and the lower mold 9 is provided with a lower cavity 10;

[0027] Both sides of the bottom of the lower mold 9 have vertically penetrating demolding pillars 11 that communicate with the lower cavity 10;

[0028] The bottom of the demolding column 11 is fitted with a lifting assembly.

[0029] The lifting assembly includes a base 16 connected to the lower template 1. A motor 15 is mounted on the base 16, and a lead screw 14 is mounted on the output shaft of the motor 15. The motor 15 is powered by existing technology. A bottom rod 13 is screwed onto the lead screw 14. Top rods 12 are mounted on both sides of the top of the bottom rod 13, and the top rods 12 penetrate the lower template 1 and contact the demolding column 11. The motor 15 drives the lead screw 14 to rotate, which causes the bottom rod 13 to drive the top rods 12 to push the demolding column 11 upward, thereby pushing the casting upward.

[0030] An installation groove 23 is provided in the lower mold 9. A slip ring 24 is slidably connected in the installation groove 23. The slip ring 24 is set on the demolding column 11. A spring 25 connected to the installation groove 23 is provided on the slip ring 24. The spring 25 is used to push the slip ring 24 to move upward, so that the demolding column 11 can automatically return to its downward position after use.

[0031] Both ends of the top of the base rod 13 are provided with fixing rods 20, and the top of the fixing rod 20 is provided with an electric push rod 19. The top of the output end of the electric push rod 19 is connected to an electric telescopic rod 17, and clamping rods 18 are provided on the output ends of the electric telescopic rods 17 on opposite sides.

[0032] The height of the electric telescopic rod 17 and the clamping rod 18 is adjusted by the electric push rod 19. Then, the electric telescopic rod 17 drives the clamping rod 18 to clamp the part of the casting that is higher than the lower mold 9. Then, the bottom rod 13 moves upward, the demolding column 11 pushes the bottom of the casting upward, and the clamping rod 18 clamps the top of the casting and moves upward along with the bottom rod 13 and the fixing rod 20. This improves the stability during demolding and avoids the problem that heavy castings are easy to tip over when they are moved out of the lower mold 9 with only the demolding column 11 for support.

[0033] Through grooves 21 are provided on both sides of the lower template 1, and the fixing rod 20 is located in the through grooves 21, which does not affect the lifting and lowering of the fixing rod 20. Example

[0034] Reference Figure 1 A controller 22 is provided on the base 16 to control the electrical components mentioned in the text.

[0035] The rest of the structure is the same as in Example 1.
