In order to achieve the above object, the technical solution adopted in the present invention is: a mold, comprising: a movable mold and a fixed mold, characterized in that: the movable mold includes a movable mold base, a mold set on the movable mold base The movable template, the push plate that can be arranged up and down on the movable mold base and located under the movable template, the push plate passes through the two sides of the movable mold base along the horizontal direction, and the The mold cores are fixed vertically on the push plate, and the mold cores can pass through the mold core holes on the movable template and move up and down with the push plate, and the mold core holes pass through the first mold core hole. A semicircular groove, side core blocks are arranged on both sides of the first semicircular groove, and a movable mold runner groove is arranged on one side of the first semicircular groove, and the movable mold runner groove It is connected with the gate groove of the movable mold through the inclined guide groove, and the first square groove connected with the first semicircular groove and the first square groove in the first square groove are also provided on the movable template. round hole, the fixed mold includes a fixed template, a cushion block arranged on the reverse side of the fixed template, a mold core groove corresponding to the mold core, and a second semicircular groove corresponding to the described first semicircular groove. Semicircular grooves, second square grooves corresponding to the first square grooves, cylindrical cores corresponding to the circular holes, fixed mold runner grooves corresponding to the movable mold runner grooves , the gate groove of the fixed mold corresponding to the gate groove of the movable mold.

Preferably, positioning pins are provided on the fixed template, and positioning pin holes matching the positioning pins are provided on the movable template.

Preferably, the runner groove of the fixed mold and the runner groove of the movable mold form a runner, the gate of the fixed mold and the gate of the movable mold form a gate, and the runner and the gate of the movable mold form a gate. The gates of the gates are connected with the inclined guide grooves.

Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art: the present invention adopts an inclined guide groove at the gate, so that the gate can be designed at any position, making mold design more convenient; The mold cavity boss in the prior art is made into a movable mold core. When taking the mold, the mold core is first extracted, and the mold can be taken out conveniently.
