Description

Technical Field

[0001] The utility model relates to the technical field of mold production, in particular to a sliding sleeve mold which facilitates demoulding of molding materials. Background Art

[0002] With the continuous development of industrial production, molds play a vital role in the manufacturing process of various products. Among the many mold types, sliding sleeve molds are widely used in various fields due to their unique structure and functions. Currently, traditional molds often have many problems in the demolding process after molding the material. For one thing, many molds are complex to operate, requiring a lot of time and manpower.

[0003] The reference patent is titled "A demoulding mechanism for carat tube production" (publication number CN220409373U). The molded carat tube is quickly positioned by a demoulding frame, and the position of the demoulding frame is limited by a positioning plate to facilitate demoulding. The demoulding frame is squeezed by a spring pressure rod so that the demoulding frame cooperates with the fastening bolts to maintain a stable position, preventing the demoulding frame structure from being unstable during the demoulding process, thereby affecting the product quality of the molded carat tube.

[0004] Based on the above patent, the existing demoulding structure for sliding sleeve molds mostly adopts extrusion demoulding. However, when dealing with molding materials of different shapes and materials, the adaptability is poor. For some materials with special shapes, demoulding is more difficult, and it may even require the use of additional tools or equipment to complete the demoulding operation, which undoubtedly increases the production cost and operation difficulty. For this reason, the utility model provides a sliding sleeve mold that facilitates the demoulding of molding materials. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a sliding sleeve mold that facilitates the demolding of molded materials, solving the problem of poor adaptability when dealing with molding materials of different shapes and materials. For some materials with special shapes, demolding is more difficult and may even require the use of additional tools or equipment to complete the demolding operation, which increases production costs and operational difficulty.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a sliding sleeve mold for convenient demoulding of molding materials, comprising a lower mold body and an upper mold body capable of clamping up and down, and auxiliary demoulding mechanisms are provided on both sides of the lower mold body and the upper mold body, and the auxiliary demoulding mechanisms include:

[0007] An inflation assembly is provided on both sides of the lower mold body, comprising two groups of airtight cylinders fixedly mounted on the outer walls of both sides of the lower mold body, and pressure rods are slidably mounted inside the two groups of airtight cylinders, the pressure rods and the airtight cylinders cooperate to form a closed cavity inside the cylinder body, a spring is sleeved on the outside of the pressure rod, and a pad is fixed at the bottom end of the pressure rod, and the pad and the airtight cylinder are respectively connected to the end portions of the spring, and a ventilation pipe is interconnected at the top end of the airtight cylinder, and the other end of the ventilation pipe leads to the mold cavity of the lower mold body;

[0008] The stretching assembly is provided on both sides of the upper mold body and is used to pull the pad and the pressure rod upward;

[0009] The guide components are arranged on both sides of the lower mold body and are used to guide the stretching component.

[0010] Preferably, the stretching assembly includes two sets of rails fixedly mounted on the outer walls of both sides of the upper mold body, and sliders are slidably mounted on the two sets of rails, and blocks are integrally formed at the ends thereof to prevent the sliders from falling off.

[0011] Preferably, a vertical rod is fixed to the lower end of the slider, and a horizontal frame is fixed to the lower end of the vertical rod, and an oblique block is integrally formed at one end of the horizontal frame.

[0012] Preferably, the cross frame is fixed with a mounting block at one end away from the oblique block, and a stretching bar is rotatably mounted on one side of the mounting block through a movable shaft, and a limiting piece is fixed to one end of the mounting block close to the stretching bar.

[0013] Preferably, the guide assembly includes connecting rods fixed to both ends of the lower mold body, and the upper end of the connecting rod is integrally formed with a guide groove rod for the inclined block to slide along the inclined line.

[0014] Preferably, a guide rod is fixed to the lower end of the upper mold body, and the guide rod can be inserted into a guide groove provided on the upper surface of the lower mold body.

[0015] Beneficial effects

[0016] The utility model provides a sliding sleeve mold that facilitates the demoulding of molded materials. Compared with the existing technology, it has the following advantages:

[0017] (1) The sliding sleeve mold that facilitates the demolding of the molding material is designed with an auxiliary demolding mechanism. When demolding is required, the upper mold body moves upward, and the stretching assembly also rises. The inclined block moves in the opposite direction under the guidance of the guide groove rod, driving the horizontal frame, vertical rod and slider to move back horizontally. At the same time, the mounting block on the horizontal frame drives the stretching bar to rise, and the stretching bar pulls the pad and pressure rod in the inflation assembly to rise. The pressure rod slides in the airtight cylinder and compresses the spring. At this time, the volume of the closed cavity inside the airtight cylinder is reduced, and the gas enters the mold cavity of the lower mold body through the vent pipe. The gas is squeezed into the gap between the molding material and the inner cavity of the mold, exerting a certain pressure on the molding material, and assisting the molding material in demolding.

[0018] (2) The sliding sleeve mold facilitates the demolding of the molded material. The stretching components on both sides of the upper mold body descend as the upper mold body descends. The rail rod in the stretching component drives the slider to descend, and the vertical rod, horizontal frame and various components on the horizontal frame at the lower end of the slider also descend accordingly. The inclined block at one end of the horizontal frame is close to the guide components on both sides of the lower mold body. The guide groove rod at the upper end of the connecting rod in the guide assembly interacts with the inclined block. As the upper mold body continues to descend, the inclined block slides along the oblique line of the guide groove rod, thereby driving the horizontal frame, vertical rod and slider to move horizontally, so that the separation of the upper and lower mold bodies is not affected while assisting demolding.
