Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold that simultaneously molds a water storage box and a water storage cover. Background Technology
[0002] An injection mold is a tool used to mold thermoplastic or thermosetting plastics into plastic products of a specific shape through injection molding. It usually consists of multiple parts. Through precise design and manufacturing, it can achieve molding control of the plastic melt and produce plastic products that meet the design requirements.
[0003] Reference Figure 1 This is a structural diagram of a water storage box and a water storage cover. The water storage box and the water storage cover are two products that can be threaded together. The water storage box and the water storage cover are made of the same material and have roughly similar shapes. Both the water storage box and the water storage cover have side plates for installation on their circumferential side walls.
[0004] However, in the existing technology, the water storage box and the water storage cover are injection molded using two separate molds, which results in high mold processing and manufacturing costs for the water storage box and the water storage cover. Utility Model Content
[0005] In order to reduce the mold manufacturing cost of water storage box and water storage cover, this application provides an injection mold for simultaneously molding water storage box and water storage cover.
[0006] The injection mold for simultaneously molding a water storage box and a water storage cap provided in this application adopts the following technical solution:
[0007] An injection mold for simultaneously molding a water storage box and a water storage cap includes a cavity plate with end molding surfaces of the water storage box and the water storage cap, a core plate with inner wall molding surfaces of the water storage box and the water storage cap, a plurality of sliding seats with outer wall molding surfaces of the water storage box and the water storage cap, and a driving assembly. The plurality of sliding seats are slidably connected to the core plate, and the driving assembly is used to drive the sliding of the plurality of sliding seats. The cavity plate is provided with an enclosing groove. When the mold is in the closed state, the plurality of sliding seats slide to abut against the adjacent sliding seats, and the enclosing groove encloses the plurality of sliding seats.
[0008] By adopting the above technical solution, during the mold closing process, the core plate and the cavity plate move to abut against each other, and the drive assembly drives several sliding seats to move to abut against each other and only cooperate with the containment groove on the cavity plate, so that the molding surfaces on the core plate, the cavity plate and several sliding blocks respectively form molding cavities for the water storage box and the water storage cover to be formed, so that the water storage box and the water storage cover can be injection molded simultaneously through one mold, reducing the mold manufacturing cost of the water storage box and the water storage cover.
[0009] Preferably, the sliding seats are arranged in a tapering shape from one end near the core plate to the end away from the core plate.
[0010] By adopting the above technical solution, it is possible for several sliding blocks to cooperate with the containment groove at the same time, and the movement of the sliding blocks can be guided during the mold closing process.
[0011] Preferably, the driving assembly includes a plurality of inclined guide rods, which are respectively fixedly connected to the cavity plate, and one end of each of the inclined guide rods passes through and is slidably connected to a plurality of sliding seats along a sliding direction inclined to the sliding seat.
[0012] By adopting the above technical solution, when the mold is opened, the cavity plate moves. Due to the inclination angle of the inclined guide rod, it slides relative to the sliding seat, so that the sliding seat moves on the core plate under the action of the inclined guide rod. When the mold is closed, the inclined guide rod pushes the sliding seat to reset, so that it returns to the molding position. Moreover, the drive is convenient and the manufacturing is convenient, which reduces the mold manufacturing cost of water storage box and water storage cover.
[0013] Preferably, each of the plurality of inclined guide rods has an abutment portion at one end near the core plate. The axial direction of the abutment portion is perpendicular to the sliding direction of the sliding seat. The sliding seat has an abutment hole that can cooperate with the abutment portion. The inclined guide rod passes through and is slidably connected in the abutment hole. When the mold is in the mold closed state, the abutment hole cooperates with the abutment portion.
[0014] By adopting the above technical solution, the movement of the sliding seat on the core plate is limited during the injection molding process through the cooperation between the abutment part and the abutment hole. This reduces the possibility of displacement of the sliding seat caused by the huge internal pressure during the injection molding process. It is also easy to manufacture and reduces the mold manufacturing cost of water storage box and water storage cover.
[0015] Preferably, the core plate is provided with multiple mating grooves that can respectively cooperate with multiple inclined guide rods. When the mold is in the mold closed state, the multiple inclined guide rods respectively cooperate with the multiple mating grooves.
[0016] By adopting the above technical solution, when the mold is in the closed state, the relative position between the core plate and the cavity plate is limited by the cooperation between the inclined guide rod and the mating groove.
[0017] Preferably, some of the sliding seats are provided with protrusions, and the remaining sliding seats are provided with grooves that can cooperate with the protrusions. When the sliding seats slide to abut against each other, the protrusions on the sliding seats cooperate with the grooves on the adjacent sliding seats.
[0018] By adopting the above technical solution, the position between the sliding seats is limited when the mold is in the closed state through the cooperation between the protrusion and the groove. It is easy to manufacture and reduces the mold manufacturing cost of water storage box and water storage cover.
[0019] Preferably, the core plate has a sliding groove, a limiting block is slidably connected in the sliding groove, a spring is installed in the sliding groove, one end of the spring abuts against the limiting block, and the other end abuts against the bottom wall of the sliding groove. The sliding seat has a first limiting groove and a second limiting groove that can cooperate with the limiting block. When the mold is in the mold-opening state, the limiting block cooperates with the first limiting groove. When the mold is in the mold-closed state, the limiting block cooperates with the second limiting groove.
[0020] By adopting the above technical solution, the position of the sliding seat in the mold-closed state and the mold-open state is limited by the cooperation between the limiting block and the first limiting groove or the second limiting groove, so as to reduce the possibility of the sliding seat sliding.
[0021] The main technical effects of this utility model are reflected in the following aspects:
[0022] 1. By setting up a driving component and several sliding seats, during the mold closing process, the core plate and the cavity plate move to abut against each other, and the several sliding seats of the driving component move to abut against each other and only cooperate with the containment groove on the cavity plate, so that the molding surfaces on the core plate, the cavity plate and several sliding blocks respectively form molding cavities for the water storage box and the water storage cap to be formed, so that the water storage box and the water storage cap can be injection molded simultaneously through one mold, reducing the mold manufacturing cost of the water storage box and the water storage cap;
[0023] 2. This utility model, by setting multiple inclined guide rods, allows the cavity plate to move during mold opening. Due to the inclination angle of the inclined guide rods, relative sliding occurs between them and the sliding seat, causing the sliding seat to move on the core plate under the action of the inclined guide rods. During mold closing, the inclined guide rods push the sliding seat to reset, returning it to the molding position. Moreover, the drive is convenient, reducing the mold manufacturing cost of water storage boxes and water storage caps.
[0024] 3. By setting an abutment part and cooperating with the abutment hole, this utility model limits the movement of the sliding seat on the core plate during the injection molding process, reducing the possibility of displacement of the sliding seat due to the huge internal pressure generated during the injection molding process. It is also easy to manufacture and reduces the mold manufacturing cost of water storage box and water storage cover. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail to make the technical solution of this application easier to understand and master.
[0035] This application discloses an injection mold for simultaneously molding a water storage box and a water storage cover.
[0036] Reference Figure 1 and Figure 6 This embodiment of an injection mold for simultaneously molding a water storage box and a water storage cap includes a cavity plate 2 with end molding surfaces of the water storage box 5 and the water storage cap 6, a core plate 1 with inner wall molding surfaces of the water storage box 5 and the water storage cap 6, two sliding seats 3 with outer wall molding surfaces of the water storage box 5 and the water storage cap 6, and a drive assembly 4. The two sliding seats 3 are slidably connected to the core plate 1, and the sliding directions of the two sliding seats 3 are opposite to each other. The two sliding seats 3 are gradually tapered from one end near the core plate 1 to the end away from the core plate 1. The drive assembly 4 is used to drive the sliding of the two sliding seats 3. The cavity plate 2 is provided with an enclosing groove 21. When the mold is in the closed state, the two sliding seats 3 slide towards the opposite side until they abut against each other, and the enclosing groove 21 encloses the two sliding seats 3.
[0037] Reference Figure 1 and Figure 6During mold closing, the core plate 1 and cavity plate 2 move to abut against each other, and the drive assembly 4 drives the two sliding seats 3 to move to abut against each other and only cooperate with the receiving groove 21 on the cavity plate 2. This allows the molding surfaces on the core plate 1, cavity plate 2, and several sliding blocks to form molding cavities for the water storage box 5 and water storage cover 6, respectively. This enables the water storage box 5 and water storage cover 6 to be injection molded simultaneously using a single mold, reducing the mold manufacturing cost of the water storage box 5 and water storage cover 6. While facilitating the simultaneous cooperation of several sliding blocks with the receiving groove 21, the sliding blocks also serve as guides during mold closing.
[0038] Reference Figure 6 and Figure 7 The drive assembly 4 includes multiple inclined guide rods 41, which are fixedly connected to the cavity plate 2. One end of each inclined guide rod 41 passes through and slidably connects to two sliding seats 3 along a sliding direction inclined to the sliding seat 3. When the mold opens, the cavity plate 2 moves. Due to the inclination angle of the inclined guide rods 41, relative sliding occurs between them and the sliding seats 3, causing the sliding seats 3 to move on the core plate 1 under the action of the inclined guide rods 41. When the mold closes, the inclined guide rods 41 push the sliding seats 3 to reset, returning them to the molding position. The drive is convenient and easy to manufacture, reducing the mold manufacturing cost of the water storage box 5 and the water storage cover 6.
[0039] Reference Figure 2 , Figure 3 and Figure 6 Multiple inclined guide rods 41 are fixedly connected to abutment portions 42 at their ends near the core plate 1. The axis of the abutment portion 42 is perpendicular to the sliding direction of the sliding seat 3. The sliding seat 3 has abutment holes 35 that can cooperate with the abutment portions 42. The inclined guide rods 41 pass through and slide within the abutment holes 35. When the mold is in the closed state, the abutment holes 35 cooperate with the abutment portions 42. Through the cooperation between the abutment portions 42 and the abutment holes 35, the movement of the sliding seat 3 on the core plate 1 is limited during the injection molding process, reducing the possibility of displacement of the sliding seat 3 due to the huge internal pressure generated during the injection molding process. It is also easy to manufacture and reduces the mold manufacturing cost of the water storage box 5 and the water storage cover 6.
[0040] Reference Figure 1 and Figure 6 The core plate 1 is provided with multiple mating grooves 11 that can respectively cooperate with multiple inclined guide rods 41. When the mold is in the closed state, the multiple inclined guide rods 41 cooperate with the multiple mating grooves 11 respectively. When the mold is in the closed state, the relative position between the core plate 1 and the cavity plate 2 is limited by the cooperation between the inclined guide rods 41 and the mating grooves 11.
[0041] Reference Figure 2 and Figure 3One of the sliding seats 3 is fixedly connected to a protrusion 31, and the other sliding seat 3 has a groove 32 that can cooperate with the protrusion 31. When the two sliding seats 3 slide to abut against each other, the protrusion 31 on the two sliding seats 3 cooperates with the groove 32 on the adjacent sliding seat 3. Through the cooperation between the protrusion 31 and the groove 32, the position between the sliding seats 3 is limited when the mold is in the mold-closed state. It is easy to manufacture and reduces the mold manufacturing cost of the water storage box 5 and the water storage cover 6.
[0042] Reference Figure 4 and Figure 5 The core plate 1 has a sliding groove 12, within which a limiting block 13 is slidably connected. A spring 14 is installed in the sliding groove 12, with one end of the spring 14 abutting against the limiting block 13 and the other end abutting against the bottom wall of the sliding groove 12. The sliding seat 3 has a first limiting groove 33 and a second limiting groove 34 that can cooperate with the limiting block 13. When the mold is in the open state, the limiting block 13 cooperates with the first limiting groove 33; when the mold is in the closed state, the limiting block 13 cooperates with the second limiting groove 34. Through the cooperation between the limiting block 13 and the first limiting groove 33 or the second limiting groove 34, the position of the sliding seat 3 is limited in the closed and open states, thereby reducing the possibility of the sliding seat 3 sliding.
[0043] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
