Description

Slider for injection mold Technical Field The utility model belongs to the technical field of molds, and particularly relates to a sliding block for an injection mold. Background The injection mould is a mould used in injection moulding technology, which is a mould used for plastic injection moulding and a tool for producing plastic products. The injection mold melts the plastic material by heating, then injects the plastic material into the cavity of the mold, and cools and forms the plastic material to finally obtain the required plastic product. The injection mold is generally composed of a movable mold and a fixed mold, a mold cavity is formed after the mold is closed, plastic materials are injected into the mold cavity under the pressure action of an injection molding machine, and a finished product can be taken out after cooling and solidification. At present, when a plastic product similar to that shown in fig. 1 is produced, the side wall of the plastic product is shaped, so that the sliding of a mold along the mold opening direction after injection molding is limited, and the demolding is difficult. The existing solution mainly adopts a mode of matching the slide block with forced demolding or two-step core-pulling demolding, but the forced demolding possibly damages a product, and the two-step core-pulling demolding can cause the mold structure to be more complex, so that the precision and the processing requirement of the mold are higher, and therefore, the method has higher practical value in realizing the molding demolding of the side wall of the product through a simplified structure. Disclosure of utility model In order to solve the problems in the prior art, the utility model aims to provide a sliding block for an injection mold, so as to realize demolding of the side wall modeling of a product in the process of opening (separating) a movable mold and a fixed mold of the injection mold. In order to achieve the technical purposes and effects, the utility model is realized by the following technical scheme: The sliding block for the injection mold comprises a movable sliding block and a fixed sliding block, wherein the contact surface of the movable sliding block and the fixed sliding block are obliquely arranged, a first spring hole for installing a first spring is formed in the opposite surface of the inclined surface of the movable sliding block, an inclined pin and a top plate mechanism capable of sliding in the movable sliding block are arranged in the movable sliding block, the inclined pin is connected in the top plate mechanism, and a control groove capable of limiting the top plate mechanism is formed in the inclined surface of the fixed sliding block. Further, the contact surface of the movable sliding block and the fixed sliding block is inclined by an angle of degrees to an angle of degrees. Furthermore, the fixed sliding block is provided with an inclined guide post, and the movable sliding block is provided with an inclined hole for the inclined guide post to penetrate. Further, a through hole is formed in the rear end of the taper pin. Further, the top plate mechanism comprises an inclined pin plate and a fixed plate fixedly connected with the inclined pin plate, wherein the inclined pin plate is provided with a connecting hole for connecting the inclined pin and a second spring hole for installing a second spring. Further, the lower extreme of fixed plate has seted up the spacing groove, move be provided with on the slider with the stopper of spacing groove adaptation, through the stopper with the cooperation of spacing groove realizes with roof mechanism restriction is in move in the slider. Furthermore, the inclined pin plate is also provided with a guide shaft, and the guide shaft is slidably arranged in the movable sliding block in a penetrating way. Further, a wear-resisting piece is arranged on the lower end face of the movable sliding block. The utility model has the beneficial effects that through arranging the taper pin and the top plate mechanism in the sliding block, the demolding of the side wall modeling of the product is realized in the mold opening process of the mold, the product quality is ensured, the mold structure is simplified, and the requirements on precision and processing are reduced, so that the cost is reduced.
