[0002] Die casting is a casting method in which molten metal quickly fills the cavity under certain conditions at high speed and high pressure, and then solidifies rapidly. The die casting mold is an important process equipment in die casting production. It plays an extremely important role in whether the production can proceed smoothly and the quality of the castings. The die casting mold also plays a decisive role in the production efficiency of die casting production. It fully controls and regulates the role of thermal balance in the die casting process.

[0003] At present, when the slider type die-casting mold is used in the market, the upper and lower molds need to be pressed tightly when the cylinder body is die-cast. The existing pressing method is to avoid deviation of the upper and lower molds. After the mold is pressed, pressure needs to be applied continuously to ensure the internal die-casting quality of the mold. Not only does the pressing take a long time, but the work efficiency is also low. In the process of pressing the upper and lower molds, the contact force between the upper and lower molds is large. This will cause damage to the mold for a long time, affecting the production quality of the die-casting parts, thereby causing a high cost of using the mold. Therefore, a slider type die-casting mold is proposed to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A slider type die-casting mold in this embodiment includes a base 1, and an adjustment limit mechanism is provided on the base 1.

[0022] See also Figure 1 , Figure 2 and Figure 3 The adjustment and limiting mechanism includes two fixing rods 2 fixedly mounted on the top of the base 1, a lower mold 3 is fixedly mounted on the top of the base 1, and a positioning block 4 is fixedly mounted on the top of the lower mold 3. The setting of the positioning block 4 plays a key role in the subsequent mold docking.

[0023] Among them, the outer sides of the two fixed rods 2 are both sleeved with connecting plates 5, and sliding holes are opened inside the connecting plates 5. The connecting plates 5 are slidably connected to the fixed rods 2 through the sliding holes, which is convenient for the connecting plates 5 to adjust the height position on the fixed rods 2 through the sliding holes. The two connecting plates 5 are fixedly connected to the upper mold 6 on the opposite side, and a positioning hole is opened at the bottom of the upper mold 6, and the position of the positioning hole corresponds to the position of the positioning block 4, which is convenient for the upper mold 6 and the lower mold 3 to achieve precise docking with the positioning hole through the positioning block 4 when the mold is closed, thereby ensuring the die-casting quality of the internal die-cast object.

[0024] Among them, a handle 7 is fixedly installed on the top of the upper mold 6, and a pressure relief hole 8 is provided on the top of the upper mold 6. The air generated by the mold during the die-casting process is discharged through the pressure relief hole 8, thereby reducing the occurrence of dangerous parts.

[0025] Among them, a limiting block 9 is fixedly installed on the side of the connecting plate 5 away from the upper mold 6. It should be supplemented that the bottom part of the limiting block 9 is provided with an inclined surface to facilitate the subsequent mold closing operation. Mounting plates 10 are fixedly installed on both sides of the base 1, and an adjusting seat 11 is fixedly installed on the top of the mounting plate 10. A movable block 12 is slidably connected inside the adjusting seat 11. A limiting groove is provided on the inner wall of the adjusting seat 11. The movable block 12 is slidably connected to the inner wall of the adjusting seat 11 through the limiting groove, which facilitates the limiting of the movable block 12 through the limiting groove, so that the movable block 12 can move stably inside the adjusting seat 11.

[0026] Among them, a spring 13 is fixedly installed on the side of the movable block 12 away from the limit block 9, and an abutment plate 14 extending to the outside of the adjustment seat 11 is fixedly installed on the side of the movable block 12 away from the spring 13. It should be supplemented that the top of the abutment plate 14 is provided with an inclined surface adapted to the bottom inclined surface of the limit block 9, and a connecting groove is provided on the side of the adjustment seat 11 close to the limit block 9. The abutment plate 14 extends to the outside of the adjustment seat 11 through the connecting groove, which facilitates the contact and mutual restraint between the abutment plate 14 and the limit block 9, thereby improving the stability of the upper mold 6 and the lower mold 3 when in contact.

[0027] Among them, the front of the movable block 12 is fixedly installed with a connecting block 15 extending to the front of the adjusting seat 11, and the front of the connecting block 15 is fixedly installed with a toggle block 16. The front of the adjusting seat 11 is provided with a first through groove, and the connecting block 15 extends to the front of the adjusting seat 11 through the first through groove and is fixedly connected with the toggle block 16, so that the staff can drive the movable block 12 to move inside the adjusting seat 11 through the first through groove when toggling the toggle block 16.

[0028] It should be noted that the slider-type die-casting mold, through the setting of the adjustment limit mechanism, with the mutual cooperation between the various structures on the base 1, can improve the docking accuracy between the upper mold 6 and the lower mold 3 when the upper mold 6 and the lower mold 3 are combined for die casting, and achieve fixation between the molds through the mutual contact between the abutment plate 14 and the limit block 9, thereby reducing the gap between the molds, improving product quality, and helping to reduce the wear caused by the contact between the upper mold 6 and the lower mold 3, thereby increasing its service life.

[0029] The working principle of the above embodiment is:

[0030] When using the slider-type die-casting mold, the connecting plate 5 is first sleeved on the outer side of the fixing rod 2, and then the upper mold 6 and the lower mold 3 are closed. At the same time, the positioning block 4 is used to achieve precise docking. During the descent of the connecting plate 5, the limit block 9 contacts the top of the abutment plate 14. During the continuous falling process, the movable block 12 is driven to compress the spring 13 by squeezing the abutment plate 14, so that the abutment plate 14 retracts and the limit block 9 moves to the bottom of the abutment plate 14. The abutment plate 14 limits the limit block 9 under the elastic force of the spring 13. The upper mold 6 and the lower mold 3 can be locked without additional operation, thereby reducing the mutual wear between the molds. After the die-casting is completed, the staff can drive the abutment plate 14 to move by turning the toggle block 16, and then the staff takes out the upper mold 6 through the handle 7 to perform the demoulding operation.
