[0002] The mold is a tool used to make molded products. Different shapes of molds can be used to make products of different shapes. Traditional molds use ejectors to eject products after molding. The design of ejectors requires the addition of ejector plates, which will increase the overall volume of the mold. Figure 1 The meat tenderizer hammer handle shown in the figure has a deep inner cavity. After molding, the handle will be tightly held on the mold core. The handle wall is thin and it is impossible to use an ejector pin to directly push the product. Therefore, how to demold the meat tenderizer hammer handle is an urgent problem to be solved.

[0032] Example

[0033] like Figure 1 The meat tenderizer hammer handle 60 is shown having a deep inner cavity.

[0034] Reference Figure 2-5 As shown, the utility model discloses a mold with detachable inserts and straight top demoulding, comprising an upper fixed plate 10, a nozzle plate 20, a fixed mold plate 30, a movable mold plate 40, and a lower fixed plate 50 from top to bottom. The fixed mold plate 30 is provided with a groove, and two side sliders 401 are arranged on the movable mold plate 40. The side sliders 401 have molding grooves 4011 on their end surfaces facing each other, and the two molding grooves 4011 are closed to form a molding cavity. Specifically, a guide rib 301 is arranged on the inner side wall of the groove, and the side slider 401 has a guide groove 4012. When the mold is closed, the fixed mold plate 30 covers the two side sliders 401 downward, and slides along the guide groove 4012 through the guide rib 301, so as to drive the two molding grooves 4011 to close and form a cavity. When the mold is opened, the fixed mold plate 30 moves upward to drive the two side sliders 401 to separate. Furthermore, a plurality of pull hooks are further provided on the movable template 40, and an inverted L-shaped groove is further provided at the bottom of the side slider 401. When the mold is opened, the pull hook will first hook the groove, and the side slider 401 can only move horizontally to prevent the side slider 401 from moving upward and breaking the handle 60. The side slider 401 can move vertically only after the pull hook is separated from the groove.

[0035] Reference Figure 6-9As shown, a base 402 is embedded on the movable template 40, and a top block insert 4021 is detachably installed on the base 402. The top block insert 4021 is locked on the base 402 by bolts, which is convenient for installation and removal. The movable template 40 is provided with a mold core 403 below the base 402. The mold core 403 can slide through the base 402 and the top block insert 4021 to be placed in the mold cavity. A push rod 4022 is provided on the bottom plate of the base 402. The push rod 4022 can slide through the movable template 40 and the lower fixed plate 50 to extend to the outside. When opening the mold, the fixed template 30 and the movable template 40 are separated, and the push rod 4022 pushes the base 402 to drive the top block insert 4021 to move upward along the mold core 403, pushing the product out of the mold core 403, that is, the demoulding of the handle 60 is achieved.

[0036] Reference Figure 6-9 As shown, a pull rod 4023 is provided at the bottom of the base 402, and a return spring is sleeved on the pull rod 4023. A stepped hole for accommodating the pull rod 4023 is provided at the bottom of the movable plate 40. Specifically, when the top rod 4022 pushes the base 402 to move upward, the pull rod 4023 also moves upward with the base 402 and compresses the spring. When the top block insert 4021 pushes the handle 60 to be demolded, the base 402 falls back onto the movable plate 40 under the action of the spring, and at the same time, the base 402 is restricted to prevent the base 402 from completely falling out of the mold core 403.

[0037] Reference Figure 6-9 As shown, a guide rod 4024 is further installed on the bottom plate of the base 402. The guide rod 4024 can slide through the movable template 40. The guide rod 4024 plays a guiding role, so that the up and down movement of the base 402 is stable and smooth.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
