Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-4 This embodiment provides a technical solution: a mold for producing valve housings, including a fixed mold 6, a movable mold 4 at the upper end of the fixed mold 6, uniformly distributed positioning grooves on the upper surface of the fixed mold 6, positioning pins 5 slidably connected in each positioning groove, and four positioning pins 5 fixedly connected to the lower surface of one movable mold 4, a top cover 1 fixedly connected to the upper surface of the movable mold 4, uniformly distributed air vents 2 on the upper surface of the top cover 1, a gate 3 on the upper surface of the top cover 1, the gate 3 communicating with the runner of the movable mold 4, a forming groove 13 on the upper surface of the fixed mold 6, and a forming groove 13 on the lower surface of the movable mold 4, uniformly distributed core-pulling blocks 8 slidably connected in the forming groove 13 on the upper surface of the fixed mold 6, and uniformly distributed clearance grooves on the upper surface of the fixed mold 6, with one end of the core-pulling block 8 away from the middle of the forming groove 13 connected to the clearance groove away from the forming groove 13. Spring 10 is fixedly connected to one end of each part. Slots are opened inside the core-pulling block 8. Fixed blocks 9 are evenly distributed and fixedly connected to the lower surface of the moving mold 4. The fixed blocks 9 are installed in conjunction with the vertically adjacent slots and clearance slots. The positioning pin 5 is inserted into the vertically adjacent positioning slots so that the moving mold 4 and the fixed mold 6 are completely fitted. At this time, the fixed blocks 9 move downward and insert into the vertically adjacent slots and clearance slots, so that the core-pulling block 8 moves towards the center of the forming groove 13. Spring 10 is in the extended state. At this time, the aluminum liquid is injected into the forming groove 13 through the gate 3. Wait for the aluminum liquid to cool and form. After the forming is completed, pull the moving mold 4 upward. The fixed blocks 9 move upward and leave the clearance slots and slots. At this time, the spring 10 contracts and pulls the core-pulling block 8 away from the center of the forming groove 13, completing the reset of the core-pulling block 8. It also includes an ejector pin fixing mechanism 11.

[0023] Ejector pin fixing mechanism 11 includes spring 111, ejector pin seat 112, limiting block 113, ejector pin 114, and pressing block 115. Ejector pin seat 112 is slidably connected to the inside of fixed mold 6. Limiting block 113 is slidably connected in a slot opened inside ejector pin seat 112. Springs 111 are evenly distributed and fixedly connected between the front surface of limiting block 113 and the front surface of the slot. Pressing block 115 is fixedly connected to the rear surface of limiting block 113. Evenly distributed sliding grooves are opened on the upper surface of ejector pin seat 112. Ejector pins 114 are slidably connected in each sliding groove. Limiting grooves are opened at the lower end of the outer surface of ejector pin 114. Base 7 is fixedly connected to the lower surface of fixed mold 6. Sliding column 12 is slidably connected inside base 7. The upper surface of sliding column 12 is fixedly connected to the lower surface of ejector pin seat 112. Pushing sliding column 12 upward causes sliding column 12 to move towards the lower surface of ejector pin seat 112. The upper moving belt ejector seat 112 moves upward, causing ejector pin 114 to move upward. Ejector pin 114 moves upward through the ejector pin groove inside the fixed mold 6 to eject the valve shell formed in the forming groove 13, completing the production of the valve shell. When it is necessary to clean ejector pin 114, open the base 7 and take out ejector seat 112. At this time, press the pressing block 115 forward. The pressing block 115 moves forward, pushing the limiting block 113 forward. Spring 111 retracts. At this time, the limiting block 113 leaves the limiting groove at the lower end of ejector pin 114. Take out ejector pin 114 for cleaning or replacement. Then insert ejector pin 114 into the sliding groove on the upper surface of ejector seat 112. At this time, release the pressing block 115. Spring 111 extends and pushes the pressing block 115 backward, so that the pressing block 115 enters the limiting groove at the lower end of ejector pin 114, completing the installation of ejector pin.

[0024] The working principle of the valve shell production mold provided by this utility model is as follows: During valve shell production, the positioning pin 5 is inserted into the vertically adjacent positioning groove to make the moving mold 4 and the fixed mold 6 completely fit together. At this time, the fixing block 9 moves downward and inserts into the vertically adjacent slot and clearance slot. The slot is an inclined structure, which makes the core-pulling block 8 move towards the center of the forming groove 13. The spring 10 is in a stretched state. At this time, the aluminum liquid is injected into the forming groove 13 through the gate 3. After the aluminum liquid cools and forms, the moving mold 4 is pulled upward, and the fixing block 9 moves upward away from the clearance slot and slot. At this time, the spring 10 contracts and pulls the core-pulling block 8 away from the center of the forming groove 13, completing the core-pulling block 8 reset. At this time, the sliding pin 12 is pushed upward, and the sliding pin 12 moves upward, which moves the ejector pin seat 112 upward. The ejector pin 114 moves upward, and through the ejector pin groove inside the fixed mold 6, it ejects the valve shell formed in the forming groove 13, completing the production of the valve shell. When the ejector pin 114 needs to be cleaned, the base 7 is opened and the ejector pin seat 112 is taken out. At this time, the pressing block 115 is pressed forward, and the pressing block 115 moves forward, pushing the limiting block 113 forward. The second spring 111 contracts, and the limiting block 113 leaves the limiting groove at the lower end of the ejector pin 114. The ejector pin 114 is then taken out for cleaning or replacement. Then, the ejector pin 114 is inserted into the sliding groove on the upper surface of the ejector pin seat 112. At this time, the pressing block 115 is released, the second spring 111 extends, and pushes the pressing block 115 backward, so that the pressing block 115 enters the limiting groove at the lower end of the ejector pin 114, completing the installation of the ejector pin.

[0025] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
