Description

Technical Field

[0001] The utility model belongs to the technical field of die-casting machines, and particularly relates to a shot head guiding and supporting device. Background Art

[0002] The large-scale die-casting machines led by the integrated die-casting of new energy vehicles have a shot head, which is a main component. Due to its extremely large weight, the shot head sags during the injection process, resulting in premature wear of the contact surface between the shot head and the lower end of the injection chamber. Or during the mold opening and following-out process, the shot head leaves the inner cavity of the injection chamber and sinks due to the loss of guidance. When retracting, the step at the rear end of the shot head is extremely likely to catch and buckle the front end face of the injection chamber, resulting in abnormal damage to the injection assembly.

[0034] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0035] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] As Figures 1-3 shown, a shot head guiding and supporting device includes a shot head 105, a shot rod 101, and a plurality of guiding blocks 103. The guiding blocks 103 are made of metallic copper. A convex ring 102 is provided on the shot rod 101. A plurality of first movable grooves 1011 are provided on the convex ring 102. The number of the first movable grooves 1011 corresponds to the number of the guiding blocks 103. The guiding blocks 103 are arranged in the first movable grooves 1011 and can move along the inner wall of the first movable grooves 1011. A first inclined surface 1012 is provided at the bottom of the first movable groove 1011. A second inclined surface 1033 is provided on the bottom surface of the guiding block 103. The second inclined surface 1033 abuts against the first inclined surface 1012.

[0037] There are three first movable grooves 1011, and the three first movable grooves 1011 are distributed at an angle of 120°. There are also three guiding blocks 103, and the outer diameter arc surface of the guiding blocks 103 fits the inner diameter of the shot chamber.

[0038] The slopes of the first inclined surface 1012 and the second inclined surface 1033 are the same, and the inclination directions of the first inclined surface 1012 and the second inclined surface 1033 are opposite.

[0039] A fixing member is provided in the first movable groove 1011. The fixing member can move relative to the guiding block 103 so that the guiding block 103 has two states of movement and fixation.

[0040] Specifically, a through cavity 1031 is provided on the guiding block 103. The fixing member is a fixing bolt 104 inserted into the through cavity 1031. A threaded groove matching with the fixing bolt 104 is provided at the bottom of the first movable groove 1011.

[0041] The through cavity 1031 has a runway-shaped structure. A fixing groove 1032 matching with the fixing bolt 104 is provided at the top of the through cavity 1031. The runway-shaped through cavity 1031 structure enables the guiding block 103 to move along the fixing bolt 104, and the fixing bolt 104 is used to limit the guiding block 103.

[0042] When the position of the guiding block 103 needs to be adjusted, the fixing bolt 104 is rotated out, and the guiding block 103 is pushed to move in the first movable groove 1011, so that the protruding part of the guiding block 103 can be adjusted to provide good support for the shot head 105.

[0043] After adopting this method, the weight of the injection plunger 105 is supported by the guiding copper block. Since the texture of metallic copper is relatively soft, the damage to the inner wall of the injection chamber is extremely small, greatly improving the service life of the injection plunger and the injection chamber. At the same time, the guiding during the retraction of the injection plunger is also solved, effectively avoiding the risk of damage to the injection assembly. Due to the design of the bottom surface of the guiding copper block and the inclined surface of the guiding groove, the compensation for wear can be easily achieved by moving the axial position of the copper block.

[0044] Since it is necessary to turn out the fixing bolts every time the guiding block is adjusted, and at the same time, in order to enable the guiding block to move normally, the fixing bolts need to be turned out by a relatively long length, which is not convenient in the adjustment of the guiding block. Therefore, as a further preferred solution, as Figures 4-8 shown, a second moving groove is provided on the side wall of the first moving groove, and the fixing member is a fixing block 202 provided in the second moving groove.

[0045] A third moving groove is provided at the top of the second moving groove, and a pushing block 203 is provided in the third moving groove. One end of the pushing block 203 extends out of the third moving groove, and the other end is located in the second moving groove; a first groove is provided on the fixing block 202, and a guiding groove 2022 is provided in the first groove; both the pushing block 203 and the fixing block 202 are made of magnets.

[0046] A plurality of convex blocks 2021 are provided on the fixing block 202, and a second groove corresponding to the convex blocks 2021 is provided on the guiding block 204.

[0047] A sliding block 2041 is provided on the guiding block 204, and a sliding groove for the sliding block 2041 to move is provided on the side wall of the first moving groove. The sliding groove is inclined, and the slope of the sliding groove is the same as the slope of the first inclined surface. The cooperation between the sliding block 2041 and the sliding groove confines the guiding block 204 in the first moving groove, so that the guiding block 204 can only move in the first moving groove. The operator can directly and safely push the guiding block 204 without worrying about the guiding block 204 moving out of the first moving groove, making the adjustment of the guiding block 204 more convenient.

[0048] When adjusting the position of the guiding block 204, push the pushing block 203 to move. When the pushing block 203 moves to the first groove, the pushing block 203 attracts the fixing block 202 to move into the second moving groove, and the fixing block 202 is disengaged from the contact with the guiding block 204, and directly push the guiding block 204 to move in the first moving groove to adjust the position of the guiding block 204; when the guiding block 204 moves to the positioning position, push the pushing block 203 to move. The pushing block 203 moves to abut against the side wall of the guiding groove 2022 and pushes the fixing block 202 to move outward of the second moving groove. The fixing block 202 abuts against the side wall of the guiding block 204, and the guiding block 204 is fixed by the cooperation of the convex blocks 2021 and the second groove; through the setting of the pushing block 203, the fixing of the guiding block 204 can be quickly released and the fixing of the guiding block 204 can be completed, making the adjustment of the guiding block 204 more convenient.

[0049] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above utility model concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
